高三英语单项填空简单题查看答案及解析

Trees should only be pruned (修剪) when there is a good and clear reason for doing so and , he number of such reasons is small . Pruning involves the cutting away of overgrown and unwanted branches , and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the tree to grow in its own way .

First , pruning may be done to make sure that trees have  desired shape or size . The object may be to get a tree of the right height , and at the same time to help the growth of small side branches , which will thicken its appearance or give it a special shape . Secondly , pruning may be done to make the tree healthier . You may cut out diseased or dead wood , or branches that are rubbing against each other and thus cause wounds . The health of a tree may be encouraged by removing branches that are blocking up the center and so preventing the free movement of air .

One result of pruning is that an open wound is left on the tree and this provides an easy entry for disease , but it is a wound that will heal (愈合) . Often there is a race between the healing and the disease as to whether the tree will live or die , so that there is a period when the tree is at risk . It should be the aim of every gardener to reduce that risk of death as far as possible . It is important to make the area , which has been pruned , smooth and clan , for healing will be slowed down by roughness . You should allow the cut surface to dry for a few hours and then paint it with one of the materials available from garden shops produced especially for this purpose . Pruning is usually done in winter , for then you can see the shape of the tree clearly without interference (妨碍) from the leaves and also it is very unlikely that the cuts you make will bleed . If this does happen , it is , of course , impossible to paint them properly .

71．Why should running be done ?

A．To make the tree grow taller .               B．To improve the shape of the tree .

C．to get rid of the small ranches .             D．To make the small branches thicker .

72．Trees become unhealthy if the gardener ________ .

A．To help a wound to dry .

B．To cover a rough surface .

C．damages some of the small side branches

D．Allows too many branches to grow in the middle

73．Why is a special material painted on the tree ?

A．To help a wound to dry .                      B．to cover a rough surface .

C．To make a wound smooth .                   D．To prevent disease entering a wound .

74．A good gardener prunes a tree ________ .

A．several times throughout the year         B．as quickly as possible

C．occasionally when necessary                 D．regularly every winter

75．What was the author’s purpose when writing this passage ?

A．To discuss different methods of pruning .

B．To introduce some common knowledge of pruning .

C．To explain how trees develop disease .

D．To give practical instruction for pruning a tree .

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(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.

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 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 the world's shrinking rainforests.

1.Rainforests can help to adjust the climate because they ______.

A．reflect more heat into the atmosphere

B．reduce the effect of heat from the sun on the earth

C．bring about high rainfall throughout the world

D．rarely cause the temperature to drop lower than 16℃

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

A．Humans have begun destroying rainforests.

B．People have a strong desire for resources.

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

D．Much carbon dioxide comes from burning rainforests.

3.It can be inferred from the text that ______.

A．we can get enough resources without rainforests

B．we will grow fewer kinds of crops in the gained land

C．the level of annual rainfall affects wind patterns

D．there is great medicine potential in rainforests

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

A．Rainforests and the Environment

B．How to Save Rainforests

C．How to Protect Nature

D．Rainforests and Medical Development
