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 l6℃. 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 l％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.

Bicycles are very popular in China. In our country you can see bicycles almost everywhere. When you walk on the road, you will find a lot of people riding bicycles to schools, shops and anywhere else. Therefore, China is known as “the kingdom of bicycles”. In China, many families have one or two bicycles.
Compared with cars, bicycles have many advantages. First, they are much cheaper than cars. Most Chinese can’t afford cars, but they can afford bicycles. Second, bicycles are small enough to park anywhere, while cars need a larger piece of land to park. What’s more, with lower speed, bicycles are safer than cars.
However, bicycles also bring some problems. Some riders don’t obey the traffic rules and some riders don’t think about others safety. So they ride too fast. During the rush hour, too many bicycles may cause traffic accidents. We still have a long way to solve the problem. Where can you see bicycles in China?
| A．In the big city | B．In the town |
| C．Almost everywhere | D．In the countryside |
“The kingdom of bicycles” here is saying.

Which of the following is NOT an advantage of bicycles
| A．Bicycles are much cheaper than cars. | B．Bicycles are more beautiful than cars |
| C．Bicycles are easy to park | D．Bicycles are safer than cars. |

| A．We should drive cars instead of riding bicycles |

When you see homework covering the kitchen table and toys are piling up around the sofa, you probably wish there was a bit more space. You are not alone. Nearly a third of parents say they feel squeezed into their homes but cannot afford to move to a bigger property, a report reveals today.
Twenty-nine perc
ent say “their property is too small to fit the size of their family—rising to 40 percent for those 34 and under”. One in four children is ‘forced to share’ a bedroom, according to the Finda-Property. Com website. Property analyst Samantha Baden said: “Afford-ability remains a key issue for families, with the average cost of a three-bedroom home around ￡193,000.”Very few can afford to buy or to rent a property of the size they want and in the area they desire to live in, according to Miss Baden.
A recent report, from investment firm LV, also found that many ‘space-starved parents’are pushed into a two-bedroom home which was perfect when they were a young couple, but has no space for three or so children. Grown-up children who cannot afford to leave homo are also adding to the problem facing families in Britain’s ‘big squeeze’.
For a home to be the correct size, which means it is not overcrowded, parents must have their own bedroom. Children under ten can share, as well as same-sex children between ten and 20.Anyone over 21 also needs their own room.
The report comes as official figures, published yesterday by the Land Registry, revealing house prices are falling sharply in every region except London. The worst – hit area is the North East where average house prices have fallen to below ￡100, 000 for the first time in seven years. However, they remain unaffordable for millions.According to Paragraph 1, the report reveals .
| A．children like to do homework in the kitchen |
| B．some families can’t afford a bigger property |
| C．only a few families have housing problem |
| D．people are satisfied with their living condition |
What Miss Baden said in Paragraph 2 means .
| A．most families don’t have enough money yet |
| B．no family could afford a three - bedroom home |
| C．it is common to live in a three - bedroom home |
| D．the price of a bigger property is still acceptable |
The report from the investment firm LV shows .
| A．young couples should live in a two - bedroom home |
| B．families with three or so children couldn’t afford a home |
| C．parents should buy houses for their grown - up children |
| D．some grown - up children couldn’t afford a separate home |
What can we learn from the last paragraph?
| A．House prices are falling down everywhere. |
| B．People are able to buy a home of correct size. |
| C．The house prices in London has not fallen down. |
| D．The North East is now an area suitable to live in. |
Now let’s look ourselves as a species in relation to ecosystem balance.Modern scientists believe that humankind, like other animals, evolved(进化) through millions of years of changes and adaptations to the environment and that our most direct evolutionary ancestor was probably an earlier species of the primate(monkey, ape) group. Despite this similarity with other creatures, however, the evolution of humankind differs from that of other species in one important and unique way.
In other species, evolution has led to specialization, both in the species abilities and in its place within the environmental structure. For example, the giraffe is much adapted to feeding on treetops, but it is also specialized and thus limited to feeding on trees and shrubs. Only with great difficulty can it bend down to graze on the ground. Similarly, the anteater is extremely well adapted to eating ants but is unable to catch or eat other animals. The same is true for countless other species.
For humankind it is opposite. Our evolution had led to a very generalized ability. Our highly developed intelligence and ability to make and handle tools mean that we can do almost anything. Humans evolved in such a way that we are able to move into every environment on Earth and even into space. No natural competitor offers great resistance, and other natural enemies such as disease have been controlled.
Said another way, we see in humankind a great imbalance between biological potential and environmental resistance. The result is the rapidly increasing world population, frequently referred to as the population explosion. Further, to support our growing population, natural ecosystems are being increasingly displaced by human habitations, agriculture, and other human supporting activities.From the passage we can infer that in the course of evolution _______.
| A．humankind is very important to earlier species, such as the primate group |
| B．human beings are limited by the environment while animals are not |
| C．human beings become more and more different from each other |
| D．humankind has experienced a generalization rather than specialization in ability |
According to the passage, primate includes such animals as _______.
| A．monkeys and anteaters | B．tigers and apes |
| C．apes and monkeys | D．monkeys and giraffes |
According to the passage, evolution has made it possible for humans to _______.
| A．increase the population |
| B．resist natural offers |
| C．go to the moon |
| D．cure all diseases |
According to the author, imbalance between biological potential and environ mental resistance has resulted in _______.
| A．the population explosion |
| B．the destruction of human habitations |
| C．the growth of natural ecosystem |
| D．the specialization of humans |
