    Scientists are trying to find new clean energies, so that they do not pollute the environment. Solar power(太阳能)is one of them.

Solar power is a kind of electricity.It takes energy from the sun by using solar panels(太阳能金属板).People usually put the solar panels on the roofs of the houses and buildings.It is the family solar power system. Some countries are even beginning to build solar power factories by setting thousands of solar panels in some place, because there is enough sunshine. Solar power panels have many advantages. The power is easy to get and will never be used up. Whenever it is sunny, there is power. The power is clean and renewable. It helps to reduce waste and pollution.It is also great for the environment. In some places,because they are too far away to send electricity or not easy to build electric power factories, solar power is especially necessary.

More and more countries,such as China, the USA,Japan and India, encourage scientists to develop technology to put solar power into use. However, the power is not as widely used as expected(预期的).

One of the difficulties is that a solar power system needs sunshine. Some countries having lots of rain, like the UK, are not suitable to develop such power systems. Secondly,a solar power factory requires a very large place to set enough solar panels to collect sunlight and change it into electricity. Maybe an area in the desert would be one of the perfect places for such a factory to build. What’s more, solar panels are expensive at present though the energy itself doesn’t cost anything.

Today scientists are working hard to develop cheaper solar power systems. Maybe one day solar power will be one of the most important clean energies in our life.

根据短文内容,选择正确答案。

1.Solar power is a kind of energy taken from        .

A.the air B.the sun C.the water D.the ground

2.Where is this passage probably from?

B.The advantages of solar power

C.The places to build the solar power plants

D.The difficulties of putting solar power into use widely

4.Which of the following sentences is NOT right?

A.Solar power is a kind of electricity

B.The solar power is suitable for every country

C.Solar panels are expensive at present

D.Scientists are working hard to develop the solar power systems

5.What can we learn from the passage?

C.Solar power is a kind of clean and useful energy

D.Solar power is much better than the other energies

 

1.B 2.B 3.D 4.B 5.C 【解析】 短文主要介绍太阳能的基本生产原理、利用现状及当前存在的困难等内容。 1.句意:太阳能是一种取自太阳的能源。 细节理解题。A.空气,B.太阳,C.水,D.大地。短文第二段第一、二句说:“Solar power is a kind of electricity. It takes energy from the sun by using solar panels.”(太阳能是一种电力。它利用太阳能电池板从太阳中获取能源。)故选B。 2.句意:这篇短文可能摘自哪里? 主旨大意题。A.海报,B.杂志,C.信件,D.食谱。这是一篇记叙文而不是应用文(信件)。文中主要介绍太阳能的基本生产原理、利用现状及当前存在的困难等内容。所以,以上内容可能摘自杂志文章,不可能出现在海报、食谱中。故选B。 3.句意:短文第四段主要讲什么? 主旨大意题。A. 利用太阳能的方法。B.太阳能的优点。C. 建造太阳能工厂的地方。D.广泛利用太阳能的困难。短文第四段以“One of the difficulties is that...Secondly...What’s more...”(其中一个困难就是……第二……另外……)等语句,有条理地、详细地介绍了广泛利用太阳能的困难。故选D。 4.句意:以下哪句是不正确的? 细节理解题。A.太阳能是一种电力。B.太阳能适用于每一个国家。C.太阳能金属板目前很昂贵。D.科学家正在努力研发太阳能系统。短文第二段第一句说:“Solar power is a kind of electricity.”(太阳能是一种电力。)所以A项正确。短文第四段第二句说:“Some countries having lots of rain, like the UK, are not suitable to develop such power systems. ”(像英国这样,有很多雨水的一些国家,不适合发展这样的电力系统。)所以B项错误。短文第四段最后一句说:“solar panels are expensive at present...”(太阳能金属板目前很贵……)所以C项正确。短文第五段第一句说:“Today scientists are working hard to develop cheaper solar power systems.”(科学家现在正在努力研发更实惠的太阳能系统。)所以D项正确。故选B。 5.句意:我们可以从短文了解什么? 细节理解题。A. 太阳能本身很昂贵。B. 太阳能会很快被用完。C.太阳能是一种洁净、有用的能源。 D.太阳能比其他能源好很多。短文第四段最后一句说:“solar panels are expensive at present though the energy itself doesn’t cost anything.”(太阳能金属板目前很昂贵,不过能源本身却不贵。)短文第二段第七句说:“The power is easy to get and will never be used up.”(太阳能)这种能源易取且永远用不完。短文第一段说:“Scientists are trying to find new clean energies...Solar power(太阳能)is one of them.”(科学家在努力找新的洁净能源……太阳能就是其中之一。)综上所述,A、B两项描述与原文不符,而短文通篇只介绍太阳能未谈到其他能源,所以排除D项。故选C。
