题目内容

If you want to keep fit, please refer to the following.

Move More

Make it a daily thing to find ways to move your body. 1. Climb stairs instead of taking the elevator. Walk your dog. Play with your kids. It doesn’t have to be an hour in the gym or a 45-minute dance class. But that’s great when you’re up to it. At the same time, move more.

Quit Smoking

Ever since 1960 when it was announced that smoking was harmful to health, Americans have been reducing their use of tobacco products. Just recently, we’ve seen more and more teens smoking. Could it be the Hollywood influence? 2. Take care! Warn your children against smoking.

While recent studies show a glass of wine or one drink a day can help protect against heart disease, more than that can cause other health problems such as liver and kidney(肝肾)disease and cancer.

Reduce Stress

Easier said than done, stress comes in many ways. 4. Spend 30 minutes a day doing something you like such as walking on the beach or in a park, reading a good book, visiting a friend, listening to relaxing music, and watching a funny movie.

Protect Yourself from Pollution

If you can’t live in a smog-free environment, at least avoid smoke-filled rooms. 5.Exercise indoors in air conditioning when air quality is good.

A. Avoid Excessive（过度的） Drinking

B. Keep a Positive Mental Outlook

C. Think carefully about what you will do.

D. Exercise outside when the smog rating is low.

E. It seems that the stars in every movie smoke cigarettes.

F. There are many things you can do to move your arms and legs.

G. Some techniques given by experts are to think positive thoughts.

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.

1.Which 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.

2.Jae 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

3.Liquid 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

More than 10 years ago,it was difficult to buy a tasty pineapple.The fruits that made it to the UK were green on the outside and,more often than not,hard with an unpleasant taste within.Then in 1966,the Del Monte Gold pineapple produced in Hawaii first hit our shelves.

The new type of pineapple looked more yellowy-gold than green.It was slightly softer on the outside and had a lot of juice inside.But the most important thing about this new type of pineapple was that it was twice as sweet as the hit-and-miss pineapples we had known.In no time,the Del Monte Gold took the market by storm,rapidly becoming the world's best-selling pineapple variety,and delivering natural levels of sweetness in the mouth,up until then only found in tinned pineapple.

In nutrition it was all good news too.This nice tasting pineapple contained four times more vitamin C than the old green variety.Nutritionists said that it was not only full of vitamins,but also good against some diseases.People were understandably eager to be able to buy this wonderful fruit.The new type of pineapple was selling fast9 and the Del Monte Gold pineapple rapidly became a fixture in the shopping basket of the healthy eater.

Seeing the growing market for its winning pineapple,Del Monte tried to keep market to itself.But other fruit companies developed similar pineapples.Del Monte turned to law for help,but failed.Those companies argued successfully that Del Monte's attempts to keep the golden pineapple for itself were just a way to knock them out the market.

Even before my father left us, my mother had to go back to work to support our family. Once I came out of the kitchen, complaining, “Mum, I can’t peel(削皮) potatoes. I have only one hand.”

Mum never looked up from sewing. “You get yourself into that kitchen and peel those potatoes,” she told me. “And don’t ever use that as an excuse for anything again!”

In the second grade, our teacher lined up my class on the playground and had each of us race across the monkey bars, swinging from one high steel rod(杆) to the next. When it was my turn, I shook my head. Some kids behind me laughed, and I went home crying.

That night I told Mum about it. She hugged me, and I saw her “we’ll see about that” look. The next afternoon, she took me back to school. At the deserted playground, mum looked carefully at the bars.

“Now, pull up with your right arm,” she advised. She stood by as I struggled to lift myself with my right hand until I could hook the bar with my other elbow. Day after day we practiced, and she praised me for every rung(横杠) I reached.

I’ll never forget the next time, crossing the rungs; I looked down at the kids who were standing with their mouths open.

One night, after a dance at my new junior high, I lay in bed sobbing. I could hear Mum came into my room. “Mum,” I said, weeping, “none of the boys would dance with me.”

For a long time, I didn’t hear anything. Then she said, “Oh, honey, someday you’ll be beating those boys off with a bat.” Her voice was faint and cracking. I peeked(偷看) out from my covers to see tears running down her cheeks. Then I knew how much she suffered on my behalf. She had never let me see her tears.

C. Strict.

D. Cold.
