【解析】

試題解析：

句意：知識(shí)是學(xué)出來的而不是被教出來的。故從句要使用一般現(xiàn)在時(shí)，排除B和D。knowledge與learn構(gòu)成被動(dòng)關(guān)系，用is learned。故選C

【題目】閱讀下面四篇短文，從每題所給的A、B、C、D四個(gè)選項(xiàng)中選出最佳選項(xiàng)。
C

Indian scientists have designed a new device that they hope will solve one of the biggest problems with the use of solar energy. They call the device a solar tree. Solar trees have metal “branches” which are just from a tall pole at different levels. Each branch holds a solar panel*. These panels have large metal boards that collect energy from the sun and turn it into electricity.
Daljit Singh Bedi is the main scientist at the Council of Scientific and Industrial Research in India. Bedi says the shape of the solar trees makes it possible to fit more solar panels in a space than traditional systems do. This means less land would be needed to produce solar energy. “It takes about four square meters of space to produce energy which may need 400 square meters of space,” he says.
Scientists believe the energy a solar tree collects will be enough to power five homes. The solar tree will make it easier to provide solar energy for homes in cities. The trees will also take less space from farmers in rural areas. Bedi says solar trees will collect more energy than normal solar panels on the tops of buildings. “This design makes the solar panels exposed more towards the sun,” he says. “And that way people are able to use 10 to 15 percent more energy.”
India has promised to reduce its greenhouse gas production. The country's promise depends heavily on increasing solar energy. The cost of solar panels has gone down in recent years. This has increased the possibility of applying solar trees in India.
Amit Kumar is the senior director of the Energy and Resources Institute in New Delhi. He says gaining access to land takes time and increases costs. He adds that it is still not clear how useful these new developments in solar power technology are. “Only when we put those trees on a large scale will we be able to get that answer,” he says.
（1）We may probably read this passage in ___________.
A.Culture Views
B.Nature and Science
C.Story Books
D.Travelling Guide Book
（2）Compared the traditional system, the main advantages of the solar tree is _____________.
A.we can see many “branches” in new solar tree
B.it surely produces more energy than traditional system
C.it's reducing India's more greenhouse gas production now
D.fewer and fewer people will use it than traditional ones
（3）What does the underlined word "this" in the fourth paragraph refer to (指代)？
A.greenhouse gas production
B.the solar panels
C.the falling cost of solar panels
D.country's promise
（4）In the last paragraph, what do you think of what Amit Kumar said?
A.Solar trees have been used on a large scale to produce electricity。
B.They won't increase land to plant solar trees。
C.The new solar trees haven't been used on a large scale to produce electricity。
D.The new solar power technology won't be useful。

【題目】

WHAT time of day do you feel most clear-headed? Are you more of a morning person? Or does it take you a few hours to get your brain going? A lot of recent studies show that we should pay attention to our body clock. It can tell us at what time of day we are a【1】to perform best, says the report.

When it comes to the human brain (大腦), many people work best later in the morning. This is because the body’s temperature takes time to rise through the day. Taking a warm shower when you w【2】up can help speed this up.

But everyone’s body clock is different and some have special patterns (模式). Morning people will get up early and work better early in the day. E【3】people will get up later but their brain work better towards the end of the day.

Studies show that we are better at some activities at certain times of the day. Physical performance is at its best b【4】3 p.m. and 6 p.m, so it’s better to exercise later in the day.

F【5】, it is best to eat during our active periods. This allows our body to burn calories better and stop our blood sugar levels (血糖水平) from getting too high.
