Question

Bicycles are a great way to get around. They’re fun to ride, especially down hills. And, as you speed along the road, you might also think of ways in which you could improve your bike— make it safer, more efficient, or more comfortable. In fact, the two-wheeled machines make for some cool science projects.

This year's Intel International Science and Engineering Fair (ISEF), held last May in Cleveland, featured（had）three bicycle projects from three countries. Like many of the other experiments presented at ISEF, the bike projects showed that some of the most interesting scientific research often begins by taking a closer look at things you care about.

Renato Angulo Chu had even grander ambitions. The 12th-grader from Lima, Peru, wanted to address some of his country's economic troubles.

"I see a problem in my country," Renato said. "If you go to the forests in Peru, in some places you cannot find electricity. If you go with my bicycle, you can turn on the lights."

Renato, 16, spent 3 years designing his special Multibike. The device looks like a fixed exercise bike. It has wires fixed along the frame and a blender strapped (fastened) to the back. Turning the pedals operates the blender. The same principle can be used to sharpen knives or sweep city streets.

The Multibike can work either as a fixed bike or as a bicycle able to travel city streets and country roads. It's made from inexpensive materials, and the user gets exercise while pedaling to operate a machine.

"You pedal the bike, and you can mix any drink you want," Renato said. More importantly, he added, the same concept could be used to bring light to houses in remote regions of the rainforest.

1.What can we learn from the first paragraph?

A．Bikes should be made more comfortable to ride.

B．You can improve your bicycle for science research.

C．Many inventions are connected with the bicycle.

D．Bicycles are the best way to go about

2.Which of the following is true according to the passage?

A．ISEF is an exhibiton displaying bicycle experiments designed by students.

B．Looking closely at things you are concerned about can lead to scientific research.

C．Renato’s improvement of the bicycle has solved the country’s great problem.

D．Renato’s special bicycle will soon be put into use in remote areas.’

3.The underlined word “address” in the third paragraph probably has the same meaning as _______.

A．make address written

B．give up

C．work at

D．speak at

4.Renato’s special Multibike has all the following  EXCEPT  ________.

A．making knives sharp	B．mixing any kind of drinks
C．producing electricity	D．operating a machine with its own electricity

5.It can be inferred that Renato’s special bicycle is mainly designed for ________.

A．distant areas in the rainforest without electricity.

B．the use of his own family to make life easier.

C．the competition of ISEF to win money to support remote rainforests

D．enough exercise by pedaling it

5.A

【解析】位置介紹了一位16歲得少年自己發(fā)明的一種新型自行車。

1.B 推理題。根據(jù)第一段后三行you might also think of ways in which you could improve your bike— make it safer, more efficient, or more comfortable. In fact, the two-wheeled machines make for some cool science projects.說明我們可以用各種科學(xué)的方法提高我們的自行車的用途。

2.B 推理題。根據(jù)第二段最后三行the bike projects showed that some of the most interesting scientific research often begins by taking a closer look at things you care about.用自行車的例子 說明更近的觀察我們關(guān)心的事物會(huì)帶來科學(xué)研究。

3.C 猜測詞義題。The 12th-grader from Lima, Peru, wanted to address some of his country's economic troubles.根據(jù)橫線后面提到的秘魯?shù)慕?jīng)濟(jì)困難，那么他想為秘魯?shù)慕?jīng)濟(jì)困難做出自己的貢獻(xiàn)，為之努力。故C正確。

4.D 細(xì)節(jié)題。根據(jù)第五段最后一句The same principle can be used to sharpen knives or sweep city streets說明A是用途。最后一段第一行"You pedal the bike, and you can mix any drink you want說明B是用途。最后一句話the same concept could be used to bring light to houses in remote regions of the rainforest. 說明可以發(fā)電來照明，故C是用途。D沒有提及。。D正確。

5.A 推斷題。根據(jù)第四段第1，2行If you go to the forests in Peru, in some places you cannot find electricity和最后一句he added, the same concept could be used to bring light to houses in remote regions of the rainforest. 都說明這種自行車可以用于沒有電的偏遠(yuǎn)的熱帶雨林地區(qū)。故A正確。
