Eyesight plays avery important role in our daily life. Every waking moment, the eyes are working to see the world around us. Over forty percent of Americans worry about losing eyesight, but it's easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight:
Schedule yearly exams.Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check. The good news is that millions of children now can have yearly eye exams and following treatment, including eyeglasses.
Protect against UV rays(紫外线).Longterm stay in the sun creates risk to your eyes. No matter what the season is, it's extremely important to wear sunglasses.
Give your eyes a break. Twothirds of Americans spend up to seven hours a day using computers or other digital products. Experts recommend that people practice the 20/20/20 rule: every 20 minutes, take a 20second break and look at something 20 feet away.
As part of a healthy diet, eat more fruits and vegetables each day. Vitamins(维生素) C and E help protect eyesight and promote eye health.
Practice safe wear and care of contact lenses(隐形眼镜).Many Americans use contact lenses to improve their eyesight. While some follow the medical guidance for wearing contact lenses, many are breaking the rules and putting their eyesight at risk. Otherwise, you may have problems such as red eyes, pain in the eyes, or a more serious condition.
A.Eat your greens.
B.Eye care should begin early in life.
C.They can properly protect your eyes.
D.Stay in good shape by taking more Vitamins.
E.Parents usually don't care about their own eyesight.
F.Always follow the doctor's advice for appropriate wear.
G.This frequent eye activity increases the risk for eye tiredness.

【题目】Bigger isn’t always better. People who are skeptical about this argument just need to look at personal computers. It is the continual shrinkage of components that have brought about the explosion of computing power and enabled these computers to be accessible to people across the world.

Inspired by this, researchers have been working on areas where making things small may mean big results. And this year, the Nobel Prize has challenged the convention of celebrating big by presenting the biggest prizes to discoveries on the smallest scales.

The committee presented the Nobel Prize for medicine to Yoshinori Ohsumi of the Tokyo Institute of Technology, for his research on “autophagy”, which is a “self-eating” process seen in cells.

What’s more, in recognition of their working on the unique nature of matter in extreme states and taking their research all the way down to an atomic scale, the Nobel Prize for physics was awarded to three British-born scientists who presently work in the US.

Another exceptional new field is that of nanotechnology(纳米技术). The Nobel Prize for chemistry was awarded to a scientist who managed to build the world’s tiniest machines out of molecules(分子), including a nano-sized car, which are so small that they are not seen by the human eye.

Small as the subjects are, the benefits of the scientists’ research are set to be huge. More importantly, their inventions may even eventually be turned into products that benefit mankind.

Ohsumi’s research on “autophagy” shines a light on common diseases such as Parkinson’s and diabetes. As for the molecular motors, they’re preparing to bring huge potential to the fields of medicine and energy. “The ground-breaking discoveries in physics have lighted a firestorm of research, and it’s only a matter of time before their research leads to advances as unimaginable to us now as computer chips were a hundred years ago,” Laura H. Greene, president-elect of the American Physical Society told The New York Times.

1The underlined word “shrinkage” in Paragraph 1 probably means .

A. reducing the size B. cutting down the cost

C. improving the quality D. strengthening the function

2What can be inferred from the passage?

A. Nano-sized cars are now popular all over the world.

B. Ohsumi's research has helped cure some common diseases.

C. Three scientists have made a great breakthrough in atomic energy.

D. The Nobel Prize used to have a preference for findings on big scales.

3What is Laura H. Greene’s attitude to the new discoveries in physics?

A. Positive B. Doubtful

C. Reserved D. Concerned.

4What is the message the passage conveys?

A. Great minds think alike.

B. Small things make a big difference.

C. Many small streams make a great river.

D. A journey of a thousand miles begins with a single step.

【题目】阅读理解
Grownups are often surprised by how well they remember something they learned as children but have never practiced ever since. A man who has not had a chance to go swimming for years can still swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still ride away. He can play catch and hit a ball as well as his son. A mother who has not thought about the words for years can teach her daughter the poem that begins “Twinkle, twinkle, little star” or remember the story of Cinderella or Goldilocks and the Three Bears.
One explanation is the law of overlearning, which can be stated as follows: Once we have learned something, additional learning trials(尝试)increase the length of time we will remember it.
In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing baseball long after we have learned them. We continue to listen to and remind ourselves of words such as “Twinkle, twinkle, little star” and childhood tales such as Cinderella and Goldilocks. We not only learn but overlearn.
The multiplication tables(乘法口诀表)are an exception to the general rule that we forget rather quickly the things that we learn in school, because they are another of the things we overlearn in childhood.
The law of overlearning explains why cramming(突击学习)for an examination, though it may result in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little overlearning, on the other hand, is really necessary for one's future development.
(1)What is the main idea of Paragraph 1?
A.People remember well what they learned in childhood.
B.Children have a better memory than grownups.
C.Poem reading is a good way to learn words.
D.Stories for children arc easy to remember.
(2)The author explains the law of overlearning by______.
A.presenting research findings
B.selling down general rules
C.making a comparison
D.using examples
(3)What does the word “they” in Paragraph 4 refer to?
A.Commonly accepted rules.
B.The multiplication tables.
C.Things easily forgotten.
D.School subjects.
(4)What is the author's opinion on cramming?
A.It leads to failure in college exams.
B.It's helpful only in a limited way.
C.It's possible to result in poor memory.
D.It increases students' learning interest.

One of the most important things in the world is friendship. In order to have friends, you have to be a friend. But how can you be a good friend at school?
Listen — Listen when they are talking. Don't say anything unless they ask you a question. Sometimes it's not necessary for you to have anything to say; they just need someone to talk to about their feelings.
Help them — If your friend is ever in need of something, be there to help them. You should try to put them first, but make sure you don't do everything they want you to do. Try to take an extra (额外的) pencil or pen with you to classes in case (以防) they forget one. Have a little extra money in your pocket in case they forget something they need.
Be there for them — Try to make something for your friend to help make them feel better in hard times. Making cards and encouraging them are among the nicest things you can do for a friend. Marilyn Monroe, a famous U.S. actor, once said, “I often make mistakes. Sometimes I am out of control. But if you can't stay with me at my worst, you are sure not to deserve (值得) to be with me at my best.” Always remember this! If you don't want to stay with your friends when they're in hard times, then you don't deserve to be with them when they're having a good time!
______ — Try to make plans with your friends. Go shopping, go for ice cream, have a party, go to a movie and so on. Take time to know each other even better by doing something you both enjoy. By planning things together, you both can have a good time. And you'll remember these things when you're all old!
(1)While your friend is talking to you about his or her feelings, you should _____.
A.give him or her some advice
B.just listen unless asked
C.calm him or her down
D.share your feelings as well
(2)When we provide help for our friends, we should _____.
A.try to do everything for them
B.put them before ourselves
C.change their bad habits first
D.ignore their faults
(3)What can we learn from Marilyn Monroe's words?
A.Life without a friend is death.
B.A friend is easier lost than found.
C.A friend in need is a friend indeed.
D.A man is known by his friends.
