Taking public transportation in the United States, you can often see people reading books on 1.way to school or work. But in China, I hardly see people reading 2.their free time.

Are people’s attitudes toward reading 3.(difference) here? Not really. Data (数据) released by Amazon China show that Chinese people still read a lot. They 4.(simple) prefer e-books over regular books. However, other data show that reading is still 5.(popular) in the US than in China. Is there a reason for this difference? I’m not sure. What I do know is that China has a rich history of literature (文学). From classic novels like Romance of the Three Kingdoms to the modern science-fiction epic The Three-Body Problem, Chinese authors 6.(create) many fantastic works so far.

Perhaps the difference starts from childhood. Reading textbooks and doing homework can make you feel quite tired. By the time you finish it, you might not feel like reading for 7.. Chinese students surely have to read more and do more homework 8.American students. So it’s no wonder that they might not want to read much in their spare time.

Learning voca bulary doesn’t have to be boring

Many students have problems with vocabulary when preparing for tests like the SATs. Last week, TEENS offered advice on how to memorize new words. If you’re now familiar with those methods, why not try moving on to the next stage by using the following tips to build up your English vocabulary. Repeated encounters (反复遇见)

The usual way of “memorizing” new material is through repeating it while it’s still in your mind. However, simply repeating a word seems to have little long-term effect.

But one kind of repetition is effective: repetition of encounters with a word. Words stand a good chance of being remembered if they’ve been met at least seven times in your reading, at intervals (相隔一段时间). So, read English magazines, newspapers, and websites regularly.

Spacing and review

It’s better to distribute (分配) memory work over a period of time rather than do it in a single session (一段时间). This is known as the “principle of distributed practice”, where new vocabulary introduced in one lesson is reviewed in the next, and then in later lessons.

Use it or lose it

Putting words to use in interesting ways helps add them to your long-term memory. In a study of vocabulary learning, students who made up their own sentences with new words and read them aloud remembered them better than those who learned the words separately and silently. Best of all, students were given the task of silently imagining a picture in their minds to go with a new word. So it might help if learners link words with a mental image.

Mix it up

Let’s face it — learning words can be really boring, but it doesn’t have to be. Thanks to the Internet, there are more interesting ways to get the job done. Try watching videos from English-speaking social media celebrities and copying the way they speak. You could even upload your own videos and try becoming a star yourself.

1.According to the passage, a good way of memorizing new words is ________.

A.simply repeating them

B.learning the words silently

C.reviewing them in one lesson

D.reading English magazines regularly

2.To make learning words more interesting, we can ________.

A.try to become a famous star

B.read new words on websites

C.make and upload our own English videos

D.draw a picture on the paper with a new word

3.What does the passage mainly talk about?

A.Where to use new words. B.How to memorize new words.

C.When to learn new words. D.What to write with new words.

14、I hurried into the store to get Christmas gifts. Suddenly, I saw a little boy holding a lovely doll. He kept touching her hair. I watched him turn to a woman and say, “Are you sure I don’t have enough money?” She said yes and told the boy not to go anywhere before she came back. Then she left.

The boy continued to hold the doll. I asked the boy who the doll was for. He said, “It’s the doll that my sister wanted so badly for Christmas. She just knew that Santa would bring it.” I told him that Santa was going to bring it. He said, “No, Santa can’t go where my sister is. I have to give the doll to my mom to take it to her.”

I asked him where his sister was. He looked at me sadly and said, “She’s gone t o heaven. My daddy said that Mom was going to be there with her.” My heart nearly stopped beating. Then the boy said, “I told my daddy to tell her not to go there until I got back.” He took out some pictures of him and said, “I want my mom to take these wi th her so she’ll never forget me. I love my mom so much that I wish she didn’t have to leave me, but Daddy said that she needed to be with my sister.”

The boy lowered his head. While he was not looking, I reached into my purse and asked him, “Shall we coun t that money again?” He grew excited and said, “Yes, I just know it has to be enough.” So I put my money with his and we began to count it. He said, “Thank you for giving me enough money.” He continued, “I just asked God to give me enough money to buy this doll, and he heard myprayer.”

Soon the woman came back and I left. I remembered a story I had read in the newspaper several days earlier about a drunk driver who hit a car. A little girl was killed and her mother was in serious condition. Two days later, I read the news that the mother had died.

15、If you want to do a school project on children's rights(权利), you can look on the Internet for some information. A United Nations website can show you plenty of useful information for the project.

The United Nations lists the rights of children. Most countries agree all of them, but some countries do not. The following are some of the most important rights of children:

Children have the right to be properly fed, clothed and sheltered (庇护)by their family. If their family can't do so, the government should take responsibility.

Children have the right to an education and medical care, which should be provided by the government. Children must not be cruelly punished (惩罚)by their parents or any others.

Children have the right to expect the government to protect them from all kinds of abuse (虐待)and neglect(忽略).

No child under fifteen should be made to fight in an army.

Children have the right to be protected from being made to work too hard to make money for other people. In some countries children do not have these rights. Many young children are made to work long hours in factories and on farms. In some countries there are so few schools that only rich children get an education. There are not enough doctors or nurses to help many children when they are sick.

The rights of children are, therefore, the rights people think children should have. They are not always the rights children really have.

1.agree with the United Nations' list of children's rights.

A.All countries B.A few countries C.No countries D.Most countries

2.Some children can't get an education because .

A.there aren't enough schools B.there are no schools

C.they come from rich families D.they want to work in factories

3.What's the main idea of this passage?

A.Children are made to work long hours on farms.

B.The United Nations website is useful for the school project.

C.Children have the right to be properly fed, clothed and sheltered.

D.The United Nations has listed the rights it thinks children should have

16、A French-language daily in Belgium has issued(出版) what is thought to be Europe’s first 3D newspaper. But you must read it with a pair of special glasses.

All the photos and ads in La Derniere Heure’s (DH) special edition(版) were given a three-dimensional effect(3D效果), but the text remained the same.

DH’s editor said there were no further 3D plans because of the costs.

Reviewers in France spoke highly o f the paper, but they said the overall result was “far from perfect”. Editor Hubert Leclercq said it took two months to get ready for the special edition, which had a higher than normal print run of 115,000 copies for the stores selling newspapers.

“We hear about 3D cinema, television and video games, so we took up the challenge,” Mr. Leclercq told the AFP news agency.

According to PC World’s French edition, readers could get the best results by holding the paper 50cm from the eyes in awell-litarea.

“It takes a few minutes to get used to pictures in 3D,” it said, noting the limited quality of the viewing lenses(镜片).

It’s said some of the images - especially the ads - had a good 3D effect, but that other pictures were not clear or difficult to look at.

1.Th e Europe’s first 3D newspaper was from.

A.Belgium B.France C.Germany

2.in La Derniere Heure’s (DH) special edition had a three-dimensional effect.

A.All the pictures and the text

B.All the ads and the text

C.All the pictures and ads

3.From the forth paragraph, we know that .

A.the 3D newspaper is very good

B.they should improve the 3D newspaper

C.they should stop issuing the 3D newspaper

4.The underlined word “well-lit” in Paragraph 7 means in Chinese.

A.照明条件好的

B.火燃烧得好的

C.光线良好的

5.Which of the following is right?

A.It took two months to get ready for the 3D newspaper.

B.It will take you a few minutes to read the pictures in 3

C.

D.All the images had a good 3D effect.

E

17、Have you seen Avatar?It’s a popular movie this year. It is three-dimensional(3D), so you may have to wear a special pair of glasses to see it. The 3D glasses make the images(图像) from the movie look like they are coming straight at you.

More and more 3D movies are coming to theaters. 3D TV sets have been produced in Japan now.

Three-dimensional technology can make TV and movies more exciting. But people with eye problems may get headaches if they spend too much time watching 3D movies.

When we look at an object(物体), each eye sees it at a different angle(角度). Our eyes send the two images to our brain(大脑), and the brain puts them together. That’s how we see depth(深度). So when we watch a 3D movie, one film projector(投影机) projects a left eye image and the other projects a right eye image. 3D glasses allow us to see a different image in each eye.

There are a lot of people walking around with very less serious eye problems. Under normal situations, the brain can adjust to their eyes so they can see things normally.

But when they are watching a 3D movie, the images projected to their eyes can’t be put together by their brain. So the brain needs to work harder at reading the images. That makes it easier for these people to get headaches.

Dr John Hagan, an eye doctor in Kansas City, said some people who do not see depth normally cannot see in 3D at all.

1.When people want to watch a three-dimensional movie, they need .

A.a ticket B.a pair of 3D glasses C.an earphone

2.Three-dimensional technology uses film projector(s) to project one movie at the same time. A.one B.two C.three

3.According to the passage, if we look at an object by only one eye, we can’t judge the excatly. A.image B.angle C.depth

4.Which statement is TRUE according to the passage?

A.In the near future, people can enjoy 3D movie by watching TV at home.

B.Whenever you wear a 3D glasses, you can see objects more clearly.

C.People who have something wrong with their brain can’t read the images of 3D movie.

5.The main idea of this passage is .

A.how to use 3D glasses to watch a 3D movie.

B.3D glasses make the movie seem alive

C.not everybody can enjoy 3D movies.

18、Every time I came home from work at midnight, I often saw a shadow (黑影) walking in our neighborhood. Was it “a night walking”? Someone walked alon e in the dark, and this always made me afraid a lot.

I think it was “a sleep walker”. So I never bothered it. But one night, when I walked past it quietly and quickly as usual, I heard a low voice.

“Do you often have to work at night?”

I was a little afraid. I looked around, but no one was nearby. I ran home as quickly as possible.

Later on, I heard it was a neighbor, an old man who has been living alone at home. He’s NOT a sleep walker. He enjoys having a walk at night. So I seldom see him in the neighborhood in the day.

It’s said that he was a soldier many years ago. He has two children, a son and a daughter. His son has a family in Shanghai. His daughter went abroad, in Sydney. He has been living alone since his wife died several years ago. Without any children living with him, he feels lonely and helpless.

I feel sorry for the old man. We might care less about our parent who lives alone. When we grow up, our parents get old. We should often go back home even though we’re busy with work.

1.When does the writer come home from work?

A.In the morning. B.At noon.

C.In the afternoon. D.At midnight.

2.How did the writer feel when he saw “the sleep walker”?

A.Afraid. B.Happy.

C.Bring. D.Excited.

3.What was the old neighbor when he was young?

A.An artist. B.A soldier.

C.An engineer. D.A biology.

4.The writer mainly wants to tell us __________.

A.We shouldn’t work at night for money.

B.Life is full of the unexpected.

C.We should often go back home to see our parents

D.It’s best to live with you r parents.

Ⅴ.书面表达
