AMy grandparents were married for over half a century, and played their own special game the time they had met each other. The goal of their game was to write the word “shmily” in a surprise place for the other to find. They took turns leaving “shmily” around the ho use, and as soon as one of them discovered it, it was their turn to hide it once more. They dragged “shmily” with their fingers through the sugar and flour containers to await whoever was preparing the next meal. “Shmily” was written in the steam left on t he mirror after a hot shower, where it would reappear bath after bath. There was no end to the places where “shmily” would pop up. Little notes with “shmily” were found on car seats, or taped to steering wheels. The notes were put inside shoes and left und er pillows. “Shmily” was written in the dust upon the mantel(壁炉架)and traced in the ashes of the fireplace. This mysterious word was as much a part of my grandparents’ house as the furniture.It took me a long time before I was able to fully appreciate my grandparents’ game. Skepticism has kept me from believing in true love—one that is pure and enduring (持久的). However, I never doubted my grandparents’ relationship. It was based on passionate affection which not everyone is lucky enough to experience.But there was a dark cloud in my grandparents’ life: my grandmoth er had breast cancer. The disease had first appeared ten years earlier. As always, Grandpa was with her every step of the way. He comforted her in their yellow room, painted that way so that she could always be surrounded by sunshine, even when she was too sick to go outside. But my grandmother grew steadily weaker until, finally, she could not leave the house any more. Then one day, what we all dreaded finally happened. Grandma was gone.“Shmily.” It was written in yellow on the pink ribbons of my grandmother’s funeral bouquet (花束). As the crowd thinned and the last mourners turned to leave, Grandpa stepped up to my grandmother’s coffin and, taking a shaky breath, he began to sing to her. Through his tears and grief, the song came: S-h-m-i-l-y: See How Much I Love You.21. The first paragraph is mainly about ________.A.what the word “shmily” meansB.how the author’s grandparents played their special gameC.how the author appreciated her grandparents’ gameD.how the author’s grandparents cared for each other22. The underlined phrase “pop up” in Paragraph 1 means ________.A. appearB. changeC. surviveD. work23. According to the passage, the author _________.A. thought the game was meaninglessB. believes everyone can experience true loveC. doubted the existence of true love at firstD. sometimes left “shmily” around the house24. Grandpa tried to make Grandma comfortable by _______.A. singing songs to her every dayB. painting the room yellowC. encouraging her to go outsideD. helping her take a hot shower every da yBA very close friend phoned me this weekend and asked a specific question about earning a few extra dollars each month online. For the benefit of keeping her name and details secret, I will call her Annie in this article. You see Annie suffers from a severe form of inaction syndrome; she is full of great ideas that never materialize into cash and she is having a problem finding the link that will achieve this.Somebody once said that knowledge is power, yet we constantly find from readers of our website that they have knowledge to burn and still do not have power. Just look at the academics in universities all around the world; they have so much knowledge that they should control the wealth of the world. In truth they work for peanuts and very few of them ever achieve the power of independence. So knowledge certainly isn’t power. Therefore, we should change that “wise” statement to: “Power is the ability to use knowledge to your own benefit.”That paragraph was inserted because Annie is a typical academic—strong on talks and plans but a little weaker on actions. In the period of a twenty-minute conversation, she expounded(阐述)a whole list of plans and ideas to make the extra few hundred dollars each month she was seeking. Any one of her many ideas was a potential money maker, but she had taken action on none of them. At one time she said, “I’m lost as to what to do next.”That was my cue(提示)to get involved. “Take action,” I advised.All that is wrong is that Annie was inactive without knowing it. In five minutes we drew up a plan of action and agreed to talk again in a month to review progress. When we finished the conversation, she sounded much happier and more motivated than when we started. Annie just needs a little push into beneficial action.25. What’s the problem with Annie?A. She has too many great ideas.B. She never puts her ideas into practice.C. She suffers from a strange illness.D. She knows little about making money online.26. What is the most important according to the author?A. The ability to use o ne’s knowledge.B. The ability to acquire knowledge.C. A great deal of knowledge.D. A good understanding of oneself.27. What can we infer from the last paragraph?A. Annie will succeed in later life.B. Annie is going towards success.C. Annie doesn’t realize her problems.D. Annie talks too much in daily life.CIncreasingly, Americans are becoming their own doctors, by going online to diagnose their symptoms, order home health tests or medical devices, or even self-treat their illnesses with drugs from Internet pharmacies(药店).Some avoid doctors because of the high cost of medicalcare, especially if they lack health insurance. Or they may stay because they find it embarrassing to discuss their weight, alcohol consumption or couch potato habits. Patients may a1so fear what they might learn about their health, or they distrust physicians because of negative experiences in the past. But playing doctors can also be a deadly game.Every day, more than six million Americans turn to the Internet for medical answers—most of them aren't nearly skeptical enough of what they find. A 2002 survey by the Pew Internet & American Life Project found that 72 percent of those surveyed believe all or most of what they read on health websites. They shouldn't. Look up “headache”, and the chances of finding reliable and complete information, free from a motivation for commercial gain, are only one in ten, reports an April 2005 Brown Medical School study. Of the l69 websites the researchers rated, only l6 scored as “high quality”. Recent studies found faulty facts about all sorts of other disorders, causing one research team to warn that a large amount of incomplete, inaccurate and even dangerous information exists on the Internet.The problem is that most people don't know the safe way to surf the Web. “They use a search engine 1ike Google, get l8 trillion choices and start clicking. But that's risky, because almost anybody can put up a site that looks authoritative, so it's hard to know whether what you're reading is reasonable or not,” says Dr. Sarah Bass from the National Cancer Institute.28. According to the text, an increasing number of Americans .A. are suffering from mental disordersB. turn to Internet pharmacies for helpC. like to play deadly games with doctorsD. are skeptical about surfing medical websites29. Some Americans stay away from doctors because they .A. find medical devices easy to operateB. prefer to be diagnosed online by doctorsC. are afraid to face the truth of their healthD. are afraid to misuse their health insurance30. According to the study of Brown Medical School .A. more than 6 million Americans distrust doctorsB. only 1/l0 of medical websites aim to make a profitC. about l/10 of the websites surveyed are of high qualityD. 72% of health websites offer incomplete and faulty facts31. Which of the following is the author's main argument?A. It's cheap to se1f-treat your own illness.B. It's embarrassing to discuss your bad habits.C. It's reasonable to put up a medical website.D. It's dangerous to be your own doctor.DI’d always dreamed of exploring Africa, ever since I read my first Tarzan comic as a child. Finally, in 2004, to celebrate my 60th birthday, I went to Tanzania to experience a safari and climb Mount Kilimanjaro, the highest mountain in Africa. Seated next to me on the flight was Tanzania’s minister of water and wildlife development. We talked for thousands of miles, and he arranged me to visit a school. When I toured the school, I was shocked. The leaky roofs turned the dirt floors into mud during the rainy season, and the walls couldn’t keep out the heat, cold or bugs. Theschool was in need of all material goods, but the kids possessed great human spirit.It broke my heart that these children had to struggle to survive, so I asked the headmaster what it would cost to feed them. As little as 20 cents per child per day, he told me. Immediately I got home, I founded Kids of Kil imanjaro. Since then we’ve grown to provide hot lunches for nearly 13,000 schoolchildren every day. The free lunch program has eased a major problem the youngsters face.I know a good education could really make a difference in these children’s lives. My p arents always stressed the importance of education. I paid my own way through college in Tokyo by teaching English to students and businesspeople. After attending university I moved to San Francisco, when I was 25 years old. In 1978 I realized my American dream when I founded my own company. My success all started with a good education.It’s amazing that something as simple as a nutritious lunch can change and enrich so many lives. Giving young people a better, healthier life can inspire them to go all the way through college and lead a movement that transforms their country.32. Why did the author go to Tanzania to celebrate his 60th birthday?A.He was curious about what Africa was like.B.He was concerned about the Africans’ miserable life.C.He wanted to get an idea of the area’s wildlife.D.He hoped to lead a movement that would transform his country.33. What is the main purpose of Kids of Kilimanjaro?A.To make sure the African kids are mentally healthy.B.To spread knowledge among the African kids.C.To build new schools for the African kids.D.To protect the African kids from hunger.34. What is the correct sequence of the following events?a.“I” founded “my” first company.b.“I” founded Kids of Kilimanjaro.c.“I” read “my” first Tarzan comic.d.“I” moved to San Francisco.A.a, c, d, bB. a, d, c, bC. c, a, d, bD. c, d, a, b35. The author believes education is important because __________.A.his parents always stressed the importance of educationB. a good education contributes to his successC.he paid his own way through college by teaching EnglishD.he’s trying to realize his American dream第二节(共5小题;每小题2分,满分10分)根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。

I haven‟t seen many of my classmates after we parte d when the college entrance examination was over. So we decided to have a get-together party this summer vacation.As you can imagine, I could hardly wait to have the day for our reunion. After several month‟s waiting, 25 of my former higher school classmates and 3 of our teachers were crowded in a small restaurant near our high school. We were more than happy to meet with each other again. Our former Chinese teacher was so excited that he even choked (窒息) to say some words. With gratitude, we thanked our teachers for their hard work; with great joy, we exchanged the happy things happening in each of our present colleges; We talked before someone shouted. “Oh, it is 11:30 now.” But no one would be the first to say goodbye to others .I shall always bear this unforgettable get-together in my mind. With time passing, I believe I will meet many new friends, but I think the friendship among high school classmates will be the purest and will be the most valuable thing to cherish.16.What is the writer probably?A. He is a middle school student.B. He is a university student.C. He is a teacher .D. He is a reporter.17. How many people came to the get-together?A. 25.B. 3.C.28.D. 2218. Which of the following is true?A. The author d idn‟t wait to have the day for their reunion.B. The author‟s Chinese teacher was not good at talking.C. The author preferred the life in the university to that of his high school .D. The author thought the friendship in high school was well worth treasuring.BIt is obvious that television brings us not only advantages but also disadvantages .At first, television is both a convenient channel of amusement, and a relatively cheap one. If we have a TV set in the family, we are not necessary to go to the cinema or theater to enjoy programme with expensive tickets. All that they have to do is press a button with a finger, and they can watch all the programmes they like, such as TV talk shows , movies, opera and so on. But some people think of it as a da nger. When we watch TV, we don‟t need to do anything . We do not even have to leave our sofa because we have a remote control in our hand. We don‟t need to make any judgment or statement about it. We are totally passive and don‟t use our head to think hard about some matters.As we all know, television keeps us informed about world events—including all the events in society, science and politics .We can get a good idea of the most remote countries and the strangest customs in their country. Of course the radio performs this service this service too, but the effect of the programme is not better than on the television. Everything we enjoy on the television is much more vivid and realistic. However, in turn there is a great danger. Usually we cannot resist the television screen, because it has a great harm for us. We have been so accustomed to enjoying the screen, so dependent on its pictures. But when our TV sets are out of order, we are surprised to find that we have much more time to do things. And at this time we actually begin to have a talk to each other again. It is really worth thinking.Of course the arguments about the advantages and disadvantages of television are on the go.We can not simply say television itself is good or bad. The truth is that how we use it determines its true value to our society.19. What is the main idea of the passage?A. How to make use of the television.B. The advantages and disadvantages of television.C. The benefit of the television.D.The history of the television.20. Television , as a channel of amusement , is______.A. not very convenientB. very expensiveC. quite dangerousD. relatively cheap21. Why are some people against TV?A. Because TV programs are not interesting.B. Because TV viewers are completely passive.C. Because TV prices are very high.D. Because TV has both advantages and disadvantages.22.According to the passage , whether TV is good or not depends on ______ .A. its qualityB. people‟s attitude towards itC. how we use itD. when we use itCA new report says more and more international students are attending colleges and universities in the United States. It also notes a large increase in the number of international students form China. These findings are from the latest edition(版) of the Open Doors Report.The report tells the record number of international students in the United States during the 2011-2012 school year. It says more than 764,400 such students were attending American colleges and universities during that period. That means an increase of almost 6% compared to one year earlier. By comparison (比较),the number of Americans who are studying overseas increased by 1%.The report says 194,000 students at American colleges and universities are from China. That is an increase of more than 23% over the year before. Peggy Blumenthal is an assistant to the president of the Institute of International Education. She says many Chinese families are able to pay for the highest-quality education for their children. The children mainly choose to study in America.“ We know many of them have enough income to be able to afford to send them anywhere in the world that they want to go. And for the most part, looking around the world, Chinese students still prefer to come to th e United States as their destination of choice.” She says.Chinese students are not the only ones who want to attend American colleges and universities . After China, India sends the second largest number of students to the United States for higher education. India has about 100,000 students in American schools. South Korea is third with about 70,000 students.Why do so many foreign students study in the United States ? Peggy Blumenthal provides one reason. “ The advantage America has is that we have a huge system and a very diverse system. So there are over four thousand universities and colleges in the United States, and what it tells us is that there is still a lot of room to contain international students.”23.What is the main idea of the passage?A. More and more international students choose to receive higher education in the USA.B. America can give foreign students the best education.C. The number of international students in America from China is increasing .D. Why more and more international students in America from China is increasing.24. The number of Chinese students at American colleges and universities has increased by ______ compared to the year before.A.6%B.23%C.1%D.20%25.How many students are studying in America for the top three countries , China , India and South Korea?A. 764,000B. 194,000C. 364,000D. 266,00026. Why do so many students choose to study in America according to Peggy Blumenthal?A. Because their education fees are low.B. Because their education quality is high.C. Because their education system is diverse and they can hold more students.D. Because America is the most developed country in the world.DUntil she was six, Oprah Winfrey lived on a farm with her grandmother. She rem embers, “One day, my grandmother was boiling clothes because at that time we didn‟t have a washing machine. I was four years old, and I remember thinking, …My life won‟t be like this. It will be better.‟ ” It is better— much better. Winfrey is a billionaire, and “the Oprah Winfrey Show”, which is watched by over 20 million people every day, has won many awards.As a little girl, Winfrey was always different. She learned to read when she was three. She read the Bible in church and was famous for being the little girl who talked a lot. Since then, talking has been the most important part of her life.She got her first big chance while at Tennessee State University. At age 17, she was offered a job at a radio station. Next, she hosted a talk show, “ People Are Talking” , which soon became very popular. People felt comfortable telling her about their lives, and people liked her warm interviewing style. After a year, the show was renamed “ The Oprah Winfrey Show” , and she was a star.Winfrey‟s real dream, though , was to be an actor.Finally, she achieved this when she starred in “ The Color Purpose” in 1985. Her performance won her an Oscar nomination(提名). She now has her own production company. Harpo Productions (“Harpo” is “Oprah” spelled backward).Winfrey says her greatest lesso n in her life is “ not living my life to please other people, but doing what my heart says”.27.When did Oprah Winfrey make up her mind that her life would be better?A. At the age of 3.B. At the age of 4.C. At the age of 6.D. At the age of 17.28.Why was Oprah Winfrey famous as a little girl?A. Because she could read the Bible and talk about it a lot.B. Because she had her own dreams.C. Because she was able to read the Bible in church.D. Because she lived with her grandmother on a farm.29. What was Winfrey‟s real dream according to the passage?A. To be a film star.B. To be a hostess for a talk show.C. To be a worker at a radio station.D. To be a producer of her own company.30. Why was Winfrey‟s talk show very popular?A. Because she was a beauty.B. Because she was a billionaire.C. Because her family was very rich.D. Because her hosting was warm.EOn my first day of high school, I asked an eleventh-grader where my class was. And he told me it was “on the fourth fl oor, next to the pool.” I found out five minutes later that we didn‟t even have a fourth floor and there was no pool either! Besides that, I didn‟t have any trouble with the older kid.I think the biggest difference between middle and high school is the homework load and size of the school. I went from maybe fifteen minutes of homework a night to several hours, so I had to learn how to make full use of time! Our class size is around 550, but joining in clubs, sports, music and other activities at school makes it easier to get to know people in every grade.The best advice I can give about the years you spend in high school is to learn things for yourself, not just to get a good grade. There have been so many tests that I‟ve prepared for the night before, got ten an A, but not remember anything later. I‟ve changed that this year, and I enjoy school so much more. Don‟t take easy classes just to have a simple year. If you have a choice between chemistry and sports, the first will prove to be a lot more useful!While drinking and smoking might be present in some middle schools, they are also around in high school. I have a lot of friends who promised they would never drink or smoke, but are now partying every weekend. If you have “fun” and spend your nights wasted instead of studying, you will regret it when you are applying for college. The “friends” who say you are a loser for not partying are really not your friends at all. It‟s hard to see your closest friends grow apart and go in different directions, but don‟t follow their footsteps. Follow your own path in life and make your own decisions.31. What happened to the writer on his first day of high school?A. He had a fight with an eleventh-grader.B. He was fooled by a schoolboy.C. He was five minutes late for class.D. He fell into a pool on the fourth floor.32.According to paragraph 2, the writer thinks that in high school _____.A. It needs hard work to finish homeworkB. There are very few activities.C. It‟s hard to meet new people there.D. T here is always much free time33. The writer advises high school students to_____.A. give up sportsB. choose useful classesC. try their best to get good gradesD. get ready for test the night before34. The passage is probably written for ______.A. high school studentsB. high school teachersC. college studentsD. sports players35. The last paragraph mainly tells us ______.A. about the trouble caused by drinking and smokingB. about the importance of making friendsC. not to go to any party in high schoolD. not to lose ourselves in high schoolFMore than 30,000 people went to the White House on Monday for the 136th Easter Egg Roll. President Barack Obama and First Lady Michelle Obama held the event by inviting thousands of kids to color and look for eggs. The theme of the day was "Hop Into Healthy, Swing Into Shape." It was part of the First Lady s"Let' s Move!"program to reduce obesity rates among American kids. Mrs. Obama spoke to young reporters about her goal to get children to eat right and keep moving."We are working to make sure that kids born today grow up healthy, learn how to have balanced meals, and get more physical activity into their lives," she said.Mrs. Obama said she wants children across the nation to understand that "exercise isn't just hard work, it' s play. If you' re running around with your dog, you' re getting exercise. If you walk up the stairs, that' s exercise, But if you' re sitting in front of the TV or on a computer game, you' re not exercising."The First Lady said that for kids who have balanced meals most of the time, having a special snack, like chocolate, will not hurt. "And if you are active, you can splurge a little more," she said. Mrs. Obama's favorite "splurge food" is French fries. But she balances her splurging by exercising almost every day. She loves to play tennis and she practices yoga."A lot of kids look up to athletes, and I think it's important for athletes to share their good habits," Mrs. Obama said. "Kids aren' t just going to wake up and be LeBron James. He's practicing and eating right and working out and training. Our athletes can be really good messengers to kids who look up to them—they can say to kids, 'If you really want to be like me, then you really do need to eat your vegetables.'"36. The purpose of the "Let's Move!" program is to .A. help kids keep healthyB. train more young reportersC. encourage kids to eat more eggsD. invite kids to visit the White House37. In Mrs. Obama's opinion, exercise .A. can be fun to doB. means hard workC. should be done outdoorsD. requires special equipment38. "Splurge food" is allowed to be eaten when .A. you don' t hurt yourselfB. you have a special snackC. you never eat French friesD. you eat right and stay active39. What can we learn from the last paragraph?A. All kids want to be LeBron James.B. It is very easy to form good habits.C. Athletes can set a good example for kids.D. Kids like the messages the athletes give them.40. In which part of a newspaper will the text most probably appear?A. Business.B. Health.C. Culture.D. Education.GMary Allen was my best friend- like the sister I ever had. We did everything together : piano lessons, movies, swimming, and horseback riding.When I was 13, my family moved away. Mary and I kept in touch through letters and we saw each other on special occasions----like my wedding and Mary‟s. Soon we were busy with children and moving to new homes, and we wrote less often. One day a card that I sent came back stamped “Address Unkown”.Over the years, I thought of Mary often. I wanted to share stories of my children and then grandchildren. And I needed to share my sorrow when my brother and then mother died. There was an empty place in my heart that only a friend like Mary could fill.One day I was reading the newspaper when I noticed a photo of a young woman who looked a lot like Mary and whose last name was Wagman- Mary‟s married name. “There must be thousands of Wagman. ” I thought, but I wrote to her anyway.She called as soon as she got my letter. “Mrs Tobin!” she said excitedly. “Mary Allen Wagman” is my mother. Minutes later I heard a voice that recognized instantly, even after 40 years. We laughed and cried and caught up on each other‟s lives.Now the empty place in my heart is filled. And there‟s one thing that Mary and I know for sure: We don‟t lose each other again.41. I want to find Mary ______________ .A. to share my storiesB. to share my sorrowC. to fill the empty in my heartD. all of the above42. The writer‟s married name is __________ .A. TobinB. WagmanC.

As is illustrated in the pictures above, some passengers eat food with strong smell, such as steamed bun with meat stuffing, making others feel disgusted. Some speak loudly on the mobile phone as if there were nobody but himself on the bus.Both of the above behaviors are socially unacceptable. They reveal an undesirable situation that some passengers lack the awareness of good public manners. Without realizing that they are sharing the communal public space, they show no respect for other bus riders. The only thing they care about is their own interest and comfort. It is strongly recommended that the government should launch a massive moral campaign to fight against this trend.As middle school students, we should attach importance to good manners in public. We should not jump the queue when waiting for the bus. Also, we should avoid annoying behaviors on the bus, such as spitting, littering, swearing, grabbing seats and so on. Only when we behave decently can we become civilized passengers.第二套答案一.单项填空1-5 CBADD 6-10 ACBAD二.完形填空11-15 ACABC 16-20 DBBDA 21-25 CADDB 26-30 DCBAD 三.阅读理解31-33 ACD四.任务型阅读1. Comparison2.

A survey has been conducted about whether it is necessary to use communal chopsticks at home.As the charts illustrate, 29% of the people surveyed use serving chopsticks when dining at home while 71% do not. Reasons vary. 52% of them think it unnecessary while 4% think it troublesome. The rest worry the practice may hurt their parents’ feelings.In my view, it is necessary to use serving chopsticks even when we dine at home. There is no denying that the suggestion of using serving chopsticks may ruin harmonious family atmosphere, especially in Chinese culture. However, as a saying goes, disease enters by the mouth. Priority should always be given to health and hygiene.If I were the daughter, I would express my gratitude for the delicious food they prepare and suggest we use a pair of serving chopsticks to prevent disease from spreading. I would also offer to do the washing if they think it would bring much trouble to use more chopsticks.第三套答案一.单项填空1-5 ADDCC 6-10 ABACB二.完形填空11-15 CBADB 16-20 ADABA 21-25 CDCDD 26-30 CACBD三.阅读理解31-33 BBD 34-39 CDBABB四.任务型阅读1. vary/differ2. necessarily3. preference4. factors5. adapt/adjust6.

They suffer a lot physically and emotionally. (31 words)The left-behind children are faced with many problems. To begin with, without parents’ protection, they are likely to become the targets of bullying and abuse. Second, not only do they have to take on the burden of farming, they also struggle to keep up with their studies. Some are slowly becoming "lagging-behind" children and some even end up abandoning school. Moreover, many children feel stressed and lonely for lack of parental care and love.In the rush for economic opportunity and growth, these left-behind children have become victims and this social problem needs a solution. The government should establish a protection network involving schools, families and communities. Moreover, migrant workers should take their responsibility as parents by accompanying their children to ensure their sound development.

Besides, the environment is relatively familiar to them and thus easy to adapt to. However, the university or major may not be their favourite and they will miss the opportunity to live independently. On the contrary, if they study in a university in another city, they may have the chance to choose their favorite major, experience a different culture and meet new people. The challenge, though, may be that they have to learn how to take care of themselves and try to fit in a new community.As for me, the most important thing to consider is whether the university can offer me the major that appeals to me. I don’t care whether it is far away from my family, since I am confident enough that I will soon learn how to get accustomed to a new life.第六套答案一.单项填空1-5 BDBAC 6-10 CDBDA二.完形填空11-15 ABBDC 16-20 ACDAB 21-25 CABAB 26-30 DCCBA三.阅读理解31-34 BADC 35-38 ACBB四.书面表达Possible version 1:支持A recent survey indicates that Chinese read on WeChat for over 40 minutes daily mostly focusing on news and friends’ updates. Experts express their approval and worries as well.Generally, I am in favor of reading on WeChat. To begin with, in an age of information explosion, limited libraries in our communities fail to satisfy citizens’ need for updates, so reading on WeChat makes up for the lack of public libraries to a certain extent. With so much updated information on WeChat, we can stay well-informed. Second, with the convenience the Internet and the smartphone bring to us, we are able to know instantly what is happening around the world. Moreover, due to its flexibility, we can take up where we have stopped reading whenever we have spare time. Therefore, it is possible for us to finish reading some novel or classic literature bit by bit.In short, it is safe to conclude that reading on WeChat is and will be an important source of information and knowledge.Possible version 2: 反对A recent survey indicates that Chinese read on WeChat for over 40 minutes daily mostly focusing on news and friends’ updates. Experts express their approval and worries as well.I tend to take the “Against” side for the following reasons. Firstly, there is a tendency that people depend on WeChat and spend too much time on it. It is harmful to everyone, especially students, who are more likely to become addicted. Secondly, WeChat is full of forwarded information, the accuracy of which is doubtful. Spreading this kind of information irresponsibly may mislead others or even cause chaos. In addition, since the main purpose of WeChat is entertainment and web browsing, readers will get distracted easily. Therefore, it is not beneficial in shaping good reading habits, especially for young readers.In short, though the benefits of WeChat are beyond doubt, people should consider its negative effects as well.。
