However, many people cannot get rid of（摆脱）mobile phones because phones have become part of daily life.As being addicted（上瘾的）to the smartphone has become a serious problem, it causes many problems in life. Most phone users look down at their phones for a long time. When hunching（弓背）or bending their neck, they put serious pressure（压力）on the neck and backbone. And this will cause a sore (酸痛的) back or a neck ache. According to studies, as high as 45% of the young people from age 16 to 24 these days have back pain because of the heavy usage of smartphones. Also, trying to focus on and look at the screen of the phone for a long time will discomfort eyes and may cause loss of vision（视力）. Besides, if someone brings the phone to sleep with, he or she will unconsciously（无意地）spend more time on the phone than sleep. It’s true that phones make life easier, but that doesn’t mean they can take control of life.To get rid of phones, you can create a phone-free time. For example, turn off your phone or stop it from the Internet after 8:00 P. M. At that time, you can spend time on anything but phone so that you won’t check on your phone. Just like smoking, phone addiction is a habit. You must replace(代替) the habit with another if you want to change it. So find a few things to do whenever you are not using your phone, such as reading a book or exercising.Of course, it’s not easy to get rid of a habit and the beginning is the most challenging. That’s why having a strong idea really makes a big difference. Remember, do not let your phone become your ________ and you become its servant（仆人）.( )1.Which one can show the number of the young people aged 16-24 who have a sore back?（阴影部分stand for the number）A.

How does the writer explain the ways to get rid of phone addiction?A.By telling a story.B. By listing some numbers.C. By comparing two facts.D. By giving an example.( )5. What’s the purpose of the passage?A. The writer wants to tell students not to use cell phones.B. The writer wants phone-users not to be addicted to phones.C. The writer wants to tell us the importance of smart phones.D. The writer wants to tell us the bad influences caused by game addiction.三、任务型阅读When my friend first suggested we should join the new Tai Chi Club at school, I hesitated (犹豫). I alwaysThe first few tai chi classes were fun and easy, and I found the moves really interesting. But after that, I found myself bored from doing the same moves over and over again. Luckily, my coach taught me how to relax myself and focus (关注) on peace of mind while doing it. With these in mind, I found my balance slowly improved and I was able to do more difficult moves. My love for tai chi returned stronger than ever.In time, I began to look into the Chinese culture behind tai chi. I discovered that playing tai chi is to keep the balance of yin and yang in the body through opposite movements: forwards and backwards, up and down, left and right, breathing in and breathing out. Finally, tai chi brings about body balance and mind peace.After taking tai chi classes, however, I had to say that I had been wrong about tai chi. It was amazing! A year of practising tai chi has made a big difference to my everyday life. I sleep better at night, and I am more lively during the day. I’m sure I will go on to practise tai chi.四．语篇填空Caroline Shawk Brooks and her husband,Samuel,had a farm in Arkansas.

Is advertisement really necessary? Billions of dollars are spent on it every year, so it must be important. After all, it’s a busy world. You have to advertise to get people’s attention to sell products!Not every company thinks that way, however. The NO-AD company doesn’t advertise intraditional ways. It sells its products by word of mouth. In this way, they can save money and keep costs down, which makes their products cheaper for customers.“Word-of-mouth advertising” happens when one person tells another about a good experience with a product or service. That next person then tells another friend, family member, or colleague (同事). And so a chain of information is created.Usually, advertisers talk about how good their product is. Although they say things like “Studies show that our product is the best,” or “Everyone loves this product,” it can sound unconvincing. It’s much more believable to hear about a product fro m a family member or friend who has used it and liked it. Our loved ones’ opinions are very important to us, so we often listen to their advice about a product.Word-of-mouth advertising has other advantages, too. It’s cost-effective (after all, it’s free) and a company doesn’t have to create a complex business plan to do it. Here is some advice for small businesses about word-of-mouth advertising.● Be prepared to talk about your company at any time. You never know who you will meet. Always carry business cards.● Only say good things about your company. Don’t say bad things about your competition.● Help other companies by recommending people to them. The more you help others, the more good luck will come back to you and that’s good business.21.Why do some companies spend lots of money on advertisements?A.To make their products very useful.B.To make the environment beautiful.C.To tell people the names of their companies.D.To attract people to their products.22.Which of the following may be a word-of-mouth advertising?A.Telling people how good the product is on TV.B.Recommending the product you like to your friends.C.Telling people the product is the best in the newspaper.D.Showing people how popular the product is on the Internet.23.What does the underlined word “unconvincing” in Paragraph 4 probably mean?A.Uncomfortable.B.Unimportant.C.Unbelievable.D.Unusual.24.What might NO-AD companies do according to the passage?A.Create complex business plans.B.Say bad things about other companies.C.Provide cheaper products for customers.D.Help other companies by wishing them good luck.25.The writer writes the passage to ________.A.find out the value of making advertisementsB.introduce people a new way of advertisingC.tell people to care more about advertisementsD.show how to sell products by advertising on TV第II卷（非选择题）三、单词拼写26.There’s little ___________ (对话) in Tom and Jerry, but it is many children’s favourite.27.Each group should __________ (提交) a report to the teacher after the survey.28.The teacher often ___________ (鼓励) us to learn English well.29.That meeting was a__________（浪费） of time because nothing was done or decided．30.Which __________（亚洲的）country are you going to for your business trip?31.I don’t think the game show is wrong ________(报道)live on TV.32.—What did your father say about your travel plan?—Nothing, He just listened in ___________(沉默).33.The news programme gave an __________(最新的)report of the accident.四、用所给单词的正确形式填空34.There are so many large parks and open spaces in_______(center) London.35.The folk________(music) say that they hope to travel around to give performances.36.He is the ________(wealth) person I have ever met, but he never shows off.37.Could you mind a list of these __________(direct)films?
