【答案】Dear editor,

I’m writing to you about a common phenomenon to draw it to the public attention.

With smart phones widely used, there are more and more Phubbings. As is often the case, when people are having meals, waiting for buses or even walking along streets, they are always addicted to their phones, heads hanging down, completely ignoring others.

The reason for the increasing number of phubbings everywhere is that smart phones nowadays can be used for people to do nearly everything, such as playing mobile games, shopping online and keeping in touch with friends through QQ. However, too much exposure to phones is harmful for their health and safety. Moreover, people engaged in phones fail to communicate well with those around them.

Personally, people should wisely use their phones to help with their work and study. Meanwhile they’d better care more about their family and friends rather than phones.

Best wishes to you!

Yours truly,

Li Hua

【题目】Eyesight plays a very 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.1Experts 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). Long-term stay in the sun creates risk to your eyes. No matter what the season is, it’s extremely important to wear sunglasses. 2

﹡Give your eyes a break. Two-thirds of Americans spend up to seven hours a day using computers or other digital products.3Experts recommend that people practice the 20/20/20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away.

4As part of a healthy diet, eat more fruits and vegetables each day. Vitamins 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.5Otherwise, 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】Batteries can power anything from small sensors to large systems. While scientists are finding ways to make them smaller but even more powerful, problems can arise when these batteries are much larger and heavier than the devices themselves. University of Missouri(MU) researchers are developing a nuclear energy source that is smaller, lighter and more efficient.

“To provide enough power, we need certain methods with high energy density(密度)”, said Jae Kwon, assistant professor of electrical and computer engineering at MU. “The radioisotope(放射性同位素) battery can provide power density that is much higher than chemical batteries.”

Kwon and his research team have been working on building a small nuclear battery, presently the size and thickness of a penny, intended to power various micro / nanoelectromechanical systems (M/NEMS). Although nuclear batteries can cause concerns, Kwon said they are safe.

“People hear the word ‘nuclear’ and think of something very dangerous,” he said, “However, nuclear power sources have already been safely powering a variety of devices, such as pace-makers, space satellites and underwater systems.”

His new idea is not only in the battery’s size, but also in its semiconductor(半导体). Kwon’s battery uses a liquid semiconductor rather than a solid semiconductor.

“The key part of using a radioactive battery is that when you harvest the energy, part of the radiation energy can damage the lattice structure of the solid semiconductor,” Kwon said, “By using a liquid semiconductor, we believe we can minimize that problem.”

Together with J. David Robertson, chemistry professor and associate director of the MU Research Reactor, Kwon is working to build and test the battery. In the future, they hope to increase the battery’s power, shrink its size and try with various other materials. Kwon said that battery could be thinner than the thickness of human hair.

1Which of the following is true of Jae Kwon?

A. He teaches chemistry at MU.

B. He is working on a nuclear energy source.

C. He developed a chemical battery.

D. He made a breakthrough in computer engineering.

2Jae Kwon gave examples in Paragraph 4_________.

A. to introduce nuclear batteries can be safely used

B. to show chemical batteries are widely applied

C. to introduce various energy sources

D. to describe a nuclear-powered system

3Liquid semiconductor is used to _________.

A. get rid of the radioactive waste

B. test the power of nuclear batteries.

C. reduce the damage to lattice structure.

D. decrease the size of nuclear batteries

【题目】A Canine Reading Buddy

Dogs and people have developed a special bond over time. Recently, however, some dogs have taken a different role in people’s lives—therapy dogs.

1 Some therapy dogs visit patients in hospitals or nursing homes, while others visit children in schools and libraries. They are there to help children become better readers.

Reading programs that use therapy dogs have been in existence for more than ten years. All therapy dogs of this program are registered with an organization that tests the dogs to make sure they have the right personality for the job.

2 Both the dogs and the handlers are volunteers with the reading program.

At the start of a reading therapy session, a child and a dog are introduced. The pair is allowed to settle down in a quiet corner together. 3 An adult handler stays nearby but generally lets the dog perform its job without interfering(干涉). Sometimes, a handler may ask a question that encourages the child to work with the dog to help the child feel more comfortable.

Not every child will be able to be part of a reading therapy program that uses dogs. A few children might be allergic to dogs or afraid of them; some children might have cultural traditions that prevent them from touching a dog. 4

Reading therapy programs inspire learning and change. 5 They spend time with human friends. For dogs that love human companionshiop and a quiet place to rest, being part of a reading therapy program can be a great way to spend a few hours each day. The readers benefit too, gaining confidence and learning that reading aloud can be a relaxing experience.

A. How do the therapy dogs benefit from it?

B. But therapy animals also serve in many other areas.

C. As the child reads, the dog usually lies quietly and listens.

D. When reading to an animal, some children may become relaxed.

E. In these circumstances, other animals are available, such as cats and parrots.

F. A therapy dog is more of a companion and is trained to help people in different ways.

G. A dog’s handler also takes a class and must pass a test to work in the therapy program.
