Question

Have you ever heard of "a ball of energy"? People often use it to describe very active children. But today we tell about an invention called the soccket, that is a real soccer ball of energy. Julia Silverman explains that in fact the soccket is a portable generator (便携式发电机).

Julin Silverman and Jessica Matthews developed the soccket as part of a group project for an engineering class at Harvard University.

There are mechanisms (装置) in a soccket. When you kick, hit or throw it, energy is then kept in it by these mechanisms instead of disappearing into the environment.

Then the user can put something directly into the ball, like a lamp, or a mobile phone charger (充电器)  so that they can get energy from it.

For every fifteen minutes of the game play, the soccket can provide enough electricity(电) for an LED lamp for three hours, and the ball can store(储藏) up to 24 hours' electricity.

The International Energy Association reported last year that nearly one and a half billion people in the world had no electricity to use, and most of them live in Africa, India and other countries in Asia.

Julia Silverman and Jessica Matthews both had experiences in developing countries before they began the project. They knew that power shortages are a serious problem in really areas.

There's an energy crisis in the world. One out of every five people in the world don't have any electricity. And besides that, there are a lot of health problems because what people use instead of the electricity are harmful choices like kerosene(煤油) lamps, which produce a lot of smoke.

Julia Silverman says the soccket ball is one small solution to a big problem.

Jessica Matthews and Julia Silverman hope their soccket ball will shine more light on the problem of power shortages. It offers people a chance to put their energy into the world's most popular sport and get some energy in return.

1.From the passage, we know the soccket is ____________.

A.an active child

C.a lamp

D.a mobile phone

2.The underlined word "crisis" in the passage means ____________.

A.a time of safety

B.a time of difficulty

C.a time of success

D.a time of pride

3.We can infer(推断) from the passage that ____________.

A.Julia Silverman has never been to developing countries before

B.Active children like to play soccket

C.kicking a soccket can let the energy disappear into the environment

D.people are expected to get some energy by playing soccket

4.The best title for the passage should be "____________".

A.The only way to produce electricity

B.The best way to solve energy crisis

C.A soccer ball that gives energy

D.An invention changing the world

Answer

1.B

2.B

3.D

4.C

【解析】

短文介绍了由 Julin Silverman and Jessica Matthews 发明的便携式发电机，以及其工作原理。

1.细节理解题，根据 But today we tell about an invention called the socket.可知，soccket就是一项发明，故选B。

2.词义猜测题，根据 One out of every five people in the world don't have any electricity. And besides that, there are a lot of health problems because what people use instead of the electricity are harmful choices like kerosene(煤油) lamps, which produce a lot of smoke. 可知，五分之一的人认为有些地方缺电，另外一些人认为使用其他能量是有害的，说明世界存在着能量困难，故选B。

3.推理判断题，根据 It offers people a chance to put their energy into the world's most popular sport and get some energy in return. 可知，人们希望在踢这种球的时候获得更多的能量，故选D。

4.最佳标题，根据文章内容可知，短文介绍了一种可以通过踢球提供能量的足球，因此A soccer ball that gives energy符合短文的意思，故选C。
