[1] Imagine a magical forest where the trees touch the sky. Due to enough rainfall, the trees grow huge and spread wide. Their tallest branches are so thick-leafed that they create a thick curtain. Even the wind does not find enough space to blow as it pleases. The climate is good for life forms of all kinds- from trees to animals, birds and insects.

[2] These forests are called tropical rainforests. Most of them are located near the equator, in Asia, Africa and South America. The rainforest of the Amazon basin in South America is one of the lushest(茂盛的) rainforests in the world. You will find more varieties of trees or animal life here than anywhere else in the world.

[3] The tropical rainforests are called the green lungs of the planet. They absorb carbon dioxide from around them to process their food and release oxygen into the air. They also contain the largest number of trees with medicinal value.

[4] But now human beings are out to ________. Many companies all over the world, especially in the West, have been attacking these rainforests for a variety of reasons – some want to make profit by cutting down trees and selling timber(木材); others are trying to be the only ones to make profit out of medicinal plants.

[5] To the outside world, the rainforest has always seemed a very dangerous place. Generations of films and literature have shown the people who live in the rainforests as dangerous and violent people who have a strange way of life.

[6] But actually, these people have a better understanding of their relationship with their environment than modern man has. Greed for profit by destroying the planet’s resources is a unique quality of societies that have become modern and use technology. One should then ask, who is more violent?

Have you ever noticed the colour of the water in a river or stream after a heavy rainfall? What do you think caused this change in colour? It is soil that has been washed into the river from the riverbank or from t}le nearby fields．

Components of Soft

Soil is made up of a number of layers（层），each having its own distinctive colour and texture．The upper layer is known as the litter．It acts like a blanket．limiting temperature changes and reducing water loss．The topsoil layer is made up of small particles of rock mixed with rotten plant and animal matter called humus（腐殖质），which is black and gives the topsoil its dark colour．This layer is usually rich in nutrients，oxygen，and water．Below the topsoil is the subsoil，a layer that contains more stones mixed with only small amounts of organic matter．This layer is lighter in colour because of the lack of humus．Beneath the soil lies a layer of bedrock．

Soil forms from the bottom up．Over time bedrock is attacked by rain, wind，frost, and snow．It is gradually broken down into smaller particles in a process called weathering．Plants begin to grow，and rotten materials enrich the topsoil．Most of the soil in Eastern Canada．for example．Was formed from weathered rock that was exposed when the ice disappeared l2．000 years ag0．

Water Beneath the Soil

Surface water collects and flows above the ground in lakes．ponds．and rivers．Once in the soil or rock，it is called groundwater．Gravity pulls groundwater through the soil in a process called percolation（渗透）．Eventually the water reaches a layer called the water table．Under this is bedrock through which water cannot percolate．

As water percolates downward，it dissolves organic matter and minerals from the soil and carries them to deeper layers．This causes a serious problem because plants require these nutrients for growth.

Soil pH

Soil can be acidic．neutral．or basic．The pH of the soil is determined by the nature of the rock

from which it was formed．and by the nature of t}le plants that grow and rot in it．

The acidity of rain and snow can lower the pH of the groundwater that enters the soil．By burning fossil fuels such as coal，oil and gasoline，humans have been contributing to higher levels of acidity in many soils．When fossil fuels are burned．gases are released into the air and then fall back to earth as acid rain．Acid soil increases出e problem of carrying nutrients to lower soil levels．As nutrients are removed，soil is less fertile．Plants grow more slowly in acidic soil，and also become easily attacked by diseases．

1.The layer of soil that provides necessary nutrients for plant growth is called．

A．1itter    B．topsoil    C．humus D．subsoil

2.According to the text．which of the following is NOT true?

A．Soil forms from weathered rock on the earth surface．

B．The deeper layer of soil is darker in colour than t}le surface soil．

C．Air pollution is partially responsible for acid soil．

D．Groundwater tends to carry away nutrients for plant growth．

3.We can infer from the passage that the water table lies________．

A．between the topsoil layer and the subsoil layer

B．in the subsoil layer above bedrock

C．between the subsoil layer and bedrock

D．in the bedrock layer beneath the subsoil

4.The underlined word “dissolve” is used to express the idea that organic matter and minerals from soil are ________．

A．rushed away into the river

B．cleaned and purified by water

C．destroyed and carried away by water

D．mixed with water and become part of it

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
