二、阅读理解

阅读下列短文，从每小题所给的 A、B、C、D四个选项中选出一个最佳选项。

A rainforest 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 heat from the sun and adjust 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 all over the world.

In the past hundred years, humans have begun destroying rainforests in search of three major resources: land

for crops, wood for paper and other products, and land for raising farm animals. This action affects the environment

as a whole. For example, a lot of carbon dioxide in the air comes from burning the rainforests. We obviously have a

need for the resources we gain from cutting trees but we will suffer much more than we will benefit.

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 it actually reduces the world’s wood supply.

Rainforests are often called the world’s drugstore. 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 the world’s shrinking（减少

的）rainforests.

1．Why can rainforests help to adjust the climate?

A．Because they reflect more heat into the atmosphere.

B．Because they bring about high rainfall throughout the world.

C．Because they rarely cause the temperature to drop lower than 16℃.

D．Because they reduce the effect of heat from the sun on the earth.

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

A．We will lose much more than we can gain.

B．Humans have begun destroying rainforests.
