高二英语单项填空中等难度题查看答案及解析

A  rainfores（雨林）is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below 16℃.Rainforests have a great effect on the world environment because they can take in（吸收） heat from the sun and adjust （调节）the climate. Without the forest cover, these areas would reflect more heat into the atmosphere，warming the rest of the world .Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters（灾害） all over the world.

In the past hundred years, humans have begun destroying rainforests in search of three major resources (资源): land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example，a lot of carbon dioxide(二氧化碳)in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit（受益）.

There are two main reasons for this. Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run （长远看）it actually reduces the world’ s wood supply.

Rainforests are often called the world’s drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in （在于）the world’s shrinking rainforests.

1..．Rainforests can help to adjust the climate because they________.

2..．What does the word “this” underlined in the third paragraph refer to?

3..What might be the best title for the text?

The idea of light pollution has developed with the increase of lights in cities. In many areas, this light makes it difficult or impossible to observe stars and planets in the night sky.

There are a number of reasons why light pollution is important. One has become clear at the Mount Wilson Observatory near Los Angeles, California. Today, light from Los Angeles makes the night sky above Mount Wilson very bright. It is no longer an important reasearch center because of light pollution.

Light pollution threatens to reduce the scientific value of research telescoples in other important observatories. They include Lick Observatory near San Jose, California and Yerkes Observatory near Chicago, Illionis.

Light pollution is the result of wasted energy. Bright light that shines into the sky is not being used to provide light where it is needed on Earth. Poorly designed lighting causes a great deal of light pollution. Lights that are brighter than necessary also cause light pollution.

Most people in America are surprised to find out that they are able to see our own galaxy(星系)，the Milky Way, with their own eyes. But about three­fourths of Americans cannot see the Miky Way because of man­made light.

Objects in the night sky are resources that provide everyone with wonder. But light pollution threatens to prevent those wonderful sights from being seen.

1.Light pollution usually occurs________.

A．in cities                               B．in the country

C．in wild areas                           D．in developing countries

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

A．Mount Wilson Observatory is the most important one in America.

B．Light pollution affects observatories only.

C．In the dark night people can observe the sky clearly.

D．Astronomers can observe the stars clearly by the lights of the cities.

3.The victims affected by the light pollution are________.

A．children          B．grown­ups         C．students          D．observatories
