本文介绍了美国著名的生物学家Edward Wilson 的著作The Future of Life中的一些有关如何开发、利用和保护自然资源的情况。
Edward Wilson is America’s, if not the world’s, leading naturalist. In The Future of Life, he takes us on a tour of the world’s natural resources(资源). How are they used? What has been lost? What remains and is it able to continue with the present speed of use? Wilson also points out the need to understand fully the biodiversity(生物多样性)of our earth.
Wilson begins with an open letter to the pioneer in environment (环境) protection, Henry David Thoreau. He compares today’s Walden Pond with that of Thoreau’s day. Wilson will use such comparisons for the rest of the book. The problem is clear: man has done great damage to his home over the years. Van the earth, with human help, be made to return to biodiversity levels that will be able to support us in the future?
Biodiversity, Wilson argues, is the key to settling many problems the earth faces today. Even our agricultural crops can gain advantages from it. A mere hundred species(物种) are the basis of our food supply, of which but twenty carry the load. Wilson suggests changing this situation by looking into ten thousand species that could be made use of, which will be a way to reduce the clearing of the natural homes of plants and animals to enlarge farming areas.
At the end of the book, Wilson discusses the importance of human values in considering the environment. If you are to continue to live on the earth, you may well read and act on the ideas in this book.
小题1: We learn from the text that Wilson cares most about ______
A.the environment for plants
B.the biodiversity of our earth
C.the wastes of natural resources
D.the importance of human values
小题2:How many species are most important to our present food supply?
A.Twenty.B.Eighty.C.One hundredD.Ten thousand.
小题3:Wilson suggests that one way to keep biodiversity is to _______.
A.learn how to farm scientifically
B.build homes for some dying species
C.make it clear what to eat
D.use more species for food
小题4: We can infer that the text is _______
A.a description of natural resources
B.a research report
C.a book review
D.an introduction to a scientist.

举一反三
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.
小题1:Rainforests can help to adjust the climate because they      
A.reflect more heat into the atmosphere
B.bring about high rainfall throughout the world
C.rarely cause the temperature to drop lower than l6℃
D.reduce the effect of heat from the sun on the earth
小题2:What does the word “this” underlined in the third paragraph refer to?
A.We will lose much more than we can gain.
B.Humans have begun destroying rainforests.
C.People have a strong desire for resources.
D.Much carbon dioxide comes from burning rainforests.
小题3:It can be inferred from the text that
A.we can get enough resources without rainforests
B.there is great medicine potential in rainforests
C.we will grow fewer kinds of crops in the gained land
D.the level of annual rainfall affects wind patterns
小题4:What might be the best title for the text?
A.How to Save Rainforests
B.How to Protect Nature
C.Rainforests and the Environment
D.Rainforests and Medical Development

下面是几则寓言小故事:
小题1:An ant went to the bank of a river to quench its thirst, and being carried away by the rush of the stream, was on the point of drowning. A dove sitting on a tree overhanging the water plucked a leaf and let it fall into the stream close to her. The ant climbed onto it and floated in safety to the bank. Shortly afterwards a birdcatcher came and stood under the tree, aiming at the dove. The ant, perceiving his design, stung him in the foot. In pain the birdcatcher shouted, and the noise made the dove take wing.
小题2:Two men were travelling together, when a bear suddenly met them on their path. One of them climbed up quickly into a tree and hid himself in the branches. The other, seeing that he must be attacked, fell flat on the ground, and when the bear came up and felt him with his snout, and smelt him all over, he held his breath, and pretended to be dead as much as he could. The bear soon left him, for he will not touch a dead body. When he disappeared, the other traveller descended from the tree, and asked his friend what it was the bear had whispered in his ear. “He gave me this advice,” his companion replied. “Never travel with a friend who deserts you at the approach of danger.”
小题3:A prince had some monkeys trained to dance. Being naturally good at learning, they showed themselves excellent pupils, and in their rich clothes and masks, they danced as well as any of the courtiers. Their performance was often repeated with great applause, till on one occasion a courtier, bent on mischief, took from his pocket a handful of nuts and threw them upon the stage. The monkeys at the sight of the nuts forgot their dancing and became (as indeed they were) monkeys instead of actors. Pulling off their masks and tearing their robes, they fought with one another for the nuts. The dancing spectacle thus came to an end in the laughter and ridicule of the audience.
小题4:A cock was once strutting up and down the farmyard among the hens when suddenly he noticed something shining in the straw. "Ho! ho!" said he, "that’s for me," and soon rooted it out from beneath the straw. It turned out to be a pearl that by some chance had been lost in the yard. “You may be a treasure,” signed the cock, “to man, but for me I would rather have a single barley-corn.”
小题5:An old man on the point of death summoned his sons around him to give them some parting advice. He ordered his servants to bring in a bunch of sticks, and said to his eldest son: "Break it." The son tried hard, but with all his efforts was unable to break the bundle. The other sons also tried, but none of them was successful. “Untie it,” said the father, “and each of you take a stick.” When they had done so, he called out to them: “Now, break,” and each stick was easily broken.

Ban the Band(乐队)?
Every year,our school has a dance for all the students.It’s a little funny seeing friends in clean shoes and trousers or colorful    36  ,instead of the usual school uniform.
Most of us think the dance is great   37 —even the teachers enjoy being there. 38 ,two weeks ago someone said that there would be no    39   band this year—only CDs.
“I don’t    40   it!”Amy cried out during the lunch break.
“Someone said the school couldn’t    41   a band,and they think it’s too noisy anyway,”added Daniel.
“Well,I don’t think it’s    42   enough without a band!”declared Angela,“and I’m going to see what can be done.”
Angela was as good as her    43  .In the afternoon she went to see the school headmaster who agreed to give the   44  some more thought.And he suggested that one   45  for having a band was to increase the price of each ticket from $5 to $10.Angela had to   46   out whether the students would like to do that.
“I need all of you to help me,”she  47  to our group before school the next day.“Mr.Berry gave me a list of all the names,and suggested we ask each one their   48   about the band and the extra cost.”
   49   the day we asked around as Angela suggested,and wrote down people’s feelings about the band and the cost.We were amazed how much    50   there was for the band and everyone agreed to pay the extra $5.
“I’m surprised,”smiled Mr. Berry,when we gave him the    51  .“I really thought that only a few people     52   their band and that the cost would be too high.OK,Angela,your next    53   is to find a good band and line them up for the dance.”
Angela was all smiles and    54   the news to Amy and Daniel.“You’re    55  ,”smiled Daniel to Angela as he thought how close they came to having a less than perfect dance.

Today about 70 countries use Daylight Saving Time (DST). Daylight Saving was first introduced during World War I in Australia. During the world wars, DST was used for the late summers beginning January 1917 and 1942, and the full summers beginning September 1942 and 1943.  
In 1967, Tasmania experienced a drought(干旱). The State Government introduced one hour of daylight saving that summer as a way of saving power and water. Tasmanians liked the idea of daylight saving and the Tasmanian Government has declared daylight saving each summer since 1968. Persuaded by the Tasmanian Government, all states except two passed a law in 1971, for a test use of daylight saving. In 1972, New South Wales, South Australia and Victoria joined Tasmania for regular daylight saving, but Queensland did not do so until 1989.
Tasmania, Queensland and South Australia have had irregular plans, often changing their dates due to politics or festivals(节日). For example, in 1992, Tasmania extended(延长)daylight saving by an extra month while South Australia began extending daylight saving by two weeks for the Adelaide Festival. Special daylight saving plans were made during the Sydney 2000 Olympic Games.
The differences in daylight saving in Australia continue to cause serious problems in transport and many other social activities. It also reduces the number of hours in the working day that are common to all centers in the country. In particular, time differences along the east coast cause major differences, especially for the broadcasters of national radio and television.
小题1:Daylight Saving Time was introduced in Tasmania _______________.
A.to stop the drought in 1967B.to support government officials
C.to pass a special law in the stateD.to save water and electricity
小题2: According to the text, which state was the last to use DST?
A.Victoria.B.Queensland.
C.South Australia.D.New South Wales.
小题3: What can we learn about DST in some Australian states?
A.It doesn’t have fixed dates.B.It is not used in festivals.
C.Its plan was changed in 2000.D.It lasts for two weeks.
小题4: What do we know about the use of DST from the last paragraph?
A.There exist some undesirable effects.B.It helps little to save energy.
C.It brings about longer working days.D.Radio and TV programs become different.

Most rain forests lie close to the equator(赤道),where the climate is often mild and there are long hours of sunshine.The warmth of the land heats the air above,causing it to rise and tiny drops of water to fall as rain.The rainfall can reach at least 98 inches a year.This wet,warm world with plenty of sunlight is perfect for plants to grow,so the trees grow fast with green leaves all the year round.The trees themselves also have an effect on the climate.They gather water from the soil and pass it out into the air through their leaves.The wet air then forms clouds,which hang over the treetops like smoke.These clouds protect the forest from the daytime heat and night-time cold of nearby deserts,keeping temperatures fit for plant growth.
Rain forests slightly farther away from the equator remain just as warm,but they have a dry season of three months or more when little rain falls.Tree leaves fall during this dry season and new leaves grow when the wet season or monsoon(雨季) begins.Thus these areas are known as the “monsoon forest”.
Another type of rain forest grows on tropical mountains.It is often called the “cloud forest” because clouds often hang over the trees like fog.
The rain forest is the ideal place for the growth of many different trees.Most of them depend on animals to eat their fruits and spread their seeds.When the fruits are eaten,the seeds inside them go undamaged through animals’ stomachs and are passed out in their droppings.The seeds lying on the forest floor then grow into new trees.
小题1:The climate of the rain forests near the equator is _______.
A.mild,wet and windyB.hot,rainy and foggy
C.hot,wet and cloudyD.warm,wet and sunny
小题2:We can learn from the passage that _______.
A.tree leaves are green all the time in the monsoon forest
B.there is a dry season in the cloud forest on tropical mountains
C.clouds help the plants in the rain forest near the deserts to grow
D.the formation of climate in the rain forest has little to do with the trees
小题3:According to the passage,_______ play the most important role in the spreading of seeds.
A.animalsB.droppingsC.fruitsD.winds
小题4:This passage is most likely to be found in _______.
A.a travel guideB.a story book
C.a technical reportD.a geography book
