President Obama’s meeting with the Dalai Lama has already made China extremely angry and stirred up Tibet advocates who thought it should have come sooner. China says Tibet is part of it, and that the meeting represents an unwanted intrusion(侵犯) into its own affairs. Many Americans still see the Dalai Lama as the representative of a people treated cruelly by Chinese rule. Many Tibetans are dissatisfied with Chinese rule, and this has led to widespread rioting(暴乱) over the past few years. Theywantself-determination; fair enough. But that seems to be the only story about Tibet that is ever told. The other story is — Looking at growth, standard of living, infrastructure(基础设施), and GDP, one thing is clear: China has treated Tibetans amiably.

Since 2001, Beijing has spent $45.4 billion on development in the Tibet Autonomous Region (TAR). The effect: double-digit GDP growth for the past nine years. About a third of the money went to infrastructure investment, including the train connecting Beijing to Lhasa. The train provides an opportunity for Tibetan goods to be sold outside of the region and for a massive increase in number of tourists, reaching more than 5.5 million in 2009 — up from close to 2 million in 2005, the year before the train. While Tibetan independence groups like Free Tibet raise concerns about the increase in tourism, Hillman，a Tibet expert, points out that “tourism is an important industry that can benefit local Tibetans.”

Infrastructure improvements have not only helped grow the economy but also have aided in modernizing remote parts of Tibet, an area with 3 million people about twice the size of France.

Though Tibet is seriously puzzled by the "special contradiction" of the Dalai Lama, the central government stressed the need for Tibet to develop using the "combination of economic growth, well-off life, a healthy eco-environment, and social stability and progress" and The government is offering Tibetans the same bargain it has offered the rest of the country: in exchange for a great rise in living standards, the government requires citizens to stop having the right to free worship and free speech. Even if Tibetan residents never signed the contract, they have benefited from its policy—a fact Obama might keep in mind when he meets the Dalai Lama.

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(晶体结构) 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.

Which of the following is true of Jae Kwon?

A. He teaches chemistry at MU.

B. He developed a chemical battery.

C. He is working on a nuclear energy source.

D. He made a breakthrough in computer engineering.

Jae Kwon gave examples in Paragraph 4_________.

A. to show chemical batteries are widely applied.

D. to introduce various energy sources.

Liquid semiconductor is used to _________.

A. get rid of the radioactive waste

B. test the power of nuclear batteries.

C. decrease the size of nuclear batteries

D. reduce the damage to lattice structure.

According to Jae Kwon, his nuclear battery _______.

A. uses a solid semiconductor

B. will soon replace the present ones.

C. could be extremely thin

D. has passed the final test.

The text is most probably a ________.

A. science news report  B. book review

31．Every solid object______reflect a sound，varying according to the size and nature of the object．

   Did you know that women’s brains are smaller than men’s? The average women’s brain weighs 10% less than men’s. Since research has shown that the bigger the brain, the cleverer the animal, men must be more intelligent(聪明的) than women. Right? Wrong. Men and women always score similarly on intelligence tests, despite the difference in brain size. Why? After years of study, researchers have concluded that it’s what’s inside that matters, not just the size of the brain. The brain consists of  “grey matter” and

It has been suggested that smaller brain appears to work faster, perhaps because the two sides of the brain are better connected in women. This means that little girls tend to learn to speak earlier, and that women can understand sorts of information from different sources at the same time. When it comes to talking to the boss on the phone, cooking dinner and keeping an eye on the baby all at the same time, it’s women who come out on top every time.

   There are other important differences between two sexes. As white matter is the key to spatial(空间的) tasks, men know better where things are in relation to other things. “A great footballer always knows where he is in relation to the other players, and he knows where to go,” says one researcher. That may explain one of life’s great mysteries: why men refuse to ask for directions … and women often need to!

   The differences begin when fetuses(胎儿) are about mine weeks old, which can be seen in the action of children ad young as one. A boy would try to climb a barrier (障碍物) before him or push it down while a girl would attract help from others. These brain differences also explain the fact that more men take up jobs that require good spatial skills, while more women speech skills. It may all go back to our ancestors(祖先) ,among whom women needed speech skills to take care of their babies and men needed spatial skills to hunt, according to one research.

   If all this disappoints you, it shouldn’t. “The brain changes throughout our lives according to what we do with it.” says a biologist.

Which of the following is true according to the first paragraph?

   A. Women’s brain is 10% less than men’s

   B. Grey matter plays the same role as white matter.

   C. Grey matter controls thinking in the brain.

   D. Both sexes have the same amount of white matter.

What can we infer from the second and third paragraphs?

   A. Women prefer doing many things at a time.

   B. Men do better dealing with one job at a time.   

   C. Women do not need to tell directions.

   D. Men have weaker spatial abilities.

Which of the following do you agree with according to the fourth paragraph?

   A. Young boys may be stronger than young girls.

   B. More women take up jobs requiring speech skills
