Question

【题目】阅读下面四篇短文，从每题所给的A、B、C、D四个选项中选出最佳选项。
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。

Answer 1

【答案】
（1）B
（2）B
（3）C
（4）C
【解析】本文介绍一种新的发明——太能树，把多个太阳能面板安装在一个支架上，节省空间，却可以创造更多的电能，但是这项发明还没有正式的使用。
⑴推理判断。A.文化视野；B.自然与科学；C.故事书；D.旅行参考。根据第一段提到的scientists，solar energy，device等可知是一篇介绍科技的文章，故选B。
⑵推理判断。根据第二段he solar trees makes it possible to fit more solar panels in a space than traditional systems do可知太阳能树能够安装比传统的系统更多的太阳能面板。因此比传统的系统产生更多的能源，故选B。
⑶词义猜测。this是指示代词，指代前文提到的内容。前一句说太阳能面板的成本近年已经下降了，这已经增加了在印度使用更多太阳能树的可能性，所以this指太阳能免费成本的下降，故选C。
⑷推理判断。根据这位高级主管所说：获得土地需要时间，也会增加成本；这些新技术到底多么有用还不清楚，只有当我们大规模的种上这些树才能够得到答案。因此可以推断这项新技术还没有大规模的被使用来发电，故选C。
