科學(xué)家通過實(shí)驗(yàn)測試黑猩猩所能馴化的程度。
1. B。句中的 though 是副詞，意為“可是”，根據(jù)下文描述的實(shí)驗(yàn)情況可知“這只黑猩猩不是一只 ordinary(普通的)黑猩猩”。
2. D。do a research on 意為“對…進(jìn)行研究”。
3. D。四個(gè)選項(xiàng)中只有 become 是連系動(dòng)詞，其后接形容詞 civilized 作表語。
4. C。下文說到：當(dāng)黑猩猩想要被抱起時(shí)，她將手指向上指；當(dāng)她想要刷牙時(shí)，則用手指刮牙齒。這說明她與人們交換的是“信息”，即 message。
5. A。根據(jù)下文：當(dāng)黑猩猩想要被抱起時(shí)，她將手指向上指；當(dāng)她想要刷牙時(shí)，她則用手指刮牙齒。這說明黑猩猩用的是“手勢語”，即 sign language。
6. D。pick up 有很多意思，如表示：拿起，撿起；收拾，整理；學(xué)會(huì)；(用車)來接，去�。桓倪M(jìn)，改善；重新開始，繼續(xù)；感染(疾病、壞習(xí)慣)等。它在本句中的意思是“抱起”。

The discovery of a dwarfed (矮個(gè)的)”human being” who lived in Flores .Indonesia, up to 18,000 years ago is changing the way we think about the human family .This “Flores Human”was three foot tall and her brain was smaller than that of the average chimp (黑猩猩),yet she and her relatives apparently lived fully human lives.They seem to have made tools ,worked together to find food and cook it,and perhaps even buried their dead with ceremony.
It was a major surprise to find tools associated with the new human family member .The tools are like those formerly seen only with European fossils (化石)from our own species;Homo sapiens (智人)；and the oldest of them were made 94,000 years ago .Homo sapiens is thought to have arrived in the island about 40,000 years ago ,much too late to be responsible for the tools .If this tiny human made the tools ,them the inside structure (結(jié)構(gòu))of its brain must have been more like our own than a chimp’s ,despite being just a third the size of ours.
This “new human” was suspected to be a dwarfed branch of Homo erectus (直立人).When creatures are separated in regions with rare resources but few enemies,being big is a disadvantage, and evolution tends to shrink them, a process known as island dwarfing.Could natural selection make a human smaller while keeping — even improving — mental ability ?Quite possibly, believes Christopher Wills of the University of California.
Has the “Flores Human” even shown the ability of language? “I find it difficult to imagine that people could make tools，use fire ,and kill large animals without fairly advanced communication.”  Wills says .Did “Flores Human” possess the basic components of human culture — such as the burying of the dead with ceremony ?  Emiliano Bruner of the Italian Institute points out that Indonesia’s hot, wet environment is bad for fossilization.It is reasonable to assume , he says ,that the 18,000-year-old bones of the most complete Flores woman were well-preserved because she was buried with special care.
67.According to the passage , “Flores Human”______.
A.lived a partly human life                        B.was a branch of Homo sapiens
C.used tools before Homo sapiens arrived    D.had a brain as a common chimp’s                    
68.The underlined part “this tiny human”in Paragraph 2 refers to _______.
A.a chimp     .   B.Flores Human C.Homo sapiens   D.Homo erectus                  
69.This passage mainly talks about______.
A.the tools made by “Flores Human”    B.the language used by “Flores Human”
C.the evolution of “Flores Human”             D. the major surprising findings about “Flores Human”      
70.According to the passage ,it is believed that “Flores Human”_______.
A.was dwarfed by its enemies                          B.could use language
C.left a lot of fossils in hot and wet enviroment D.reached Flores 40,000 years ago

While parents, particularly mothers, have always been attached to their infants (嬰兒), societal conditions frequently made this attachment difficult to maintain (保持). First of all, the high infant death rate in the premodern times meant that such attachments often ended in hopelessness. Perhaps to prevent the sadness that infant death caused, a number of societal practices developed which worked against early attachment of mother and child.
One of these premodern attachment-discouraging practices was to leave infants unnamed until they had survived into the second year. Another practice that discouraged maternal (母親的) attachment was tightly wrapping (包裹) infants. Wrapping effectively prevented the close physical interactions like stroking (撫摸) and kissing that are so much a part of modern mothers' and fathers' affection for their infants.
A third practice which had the same distancing effect was wet-nursing. Breast-feeding (母乳哺育) was not popular among the well-to-do in the early modern times; infants were often fed by wet nurses hired for the purpose. In some places, such as nineteenth-century France, city infants were sent to wet nurses in the country. Often a wet nurse would feed her own child first, leaving little milk for the city infant—who, in many cases, died. In Rouen, the death rate for children sent to a wet nurse was 35 percent.
68. Babies were unnamed until they were two so that _______.
A. an old social custom could be kept up        B. maternal attachment could be maintained
C. they could have better chances to survive   D. their parents would not be too sad if they died
69. Why were babies wrapped?
A. To protect them from the cold.          B. To distance their mothers from them.
C. To make them feel more comfortable. D. To make it easy for their mothers to hold them.
70. Wet nurses were women who________.
A. babysat city infants                           B. fed babies of other families
C. sent their babies to the country           D. failed to look after their babies
71. Which is the best title for the passage?
A. Societal Conditions in Premodern Times
B. Practices of Reducing Maternal Attachment
C. Poor Health Service and High Infant Death Rate
D. Differences between Modem and Premodern Parents

The Migration of Birds
Here is a scientific experiment on the homing of birds, the fact of which are quite certain. A few years ago seven swallows were caught near their nests at Bremen in Germany. They were marked with a red dye on some of their white feathers, so that they could easily been seen. Then they were taken by plane to Croydon, near London. This is a distance of 400 miles.
Then the seven swallows were set free at Croydon. Five of them flew back to their nests at Bremen. How did the birds find their way on that long journey, which they had never made before? That is the great puzzle. It is no good saying that the swallows have a sense of direction. These are just words and explain nothing. We want to know exactly what senses the animals use to find their way, how they know in which direction to go until they can see familiar landmarks. Unfortunately practically no scientific experiments have yet been made on this question.
Perhaps migrating birds are the greatest mystery of all. Swallows leave England in August and September, and they fly to Africa, where they stay during our winter. The swallows return to England in the late summer for the south. A lot has been found about the journeys of migrating birds by marking the birds with aluminum rings put on one leg. An address and a number is put on the ring.
Swallows from England go as far as South Africa and as many as fourteen birds, marked with rings in England, have been caught again in South Africa. From England to South Africa is a journey of 6,000 miles. And the birds not only return from Africa to England next spring, but often they come back to the nests in the very same house where they nested the year before.
17．The seven swallows were marked on some of their feathers because       .
A．they would be taken away by plane
B．they would be free in London
C．Croydon was 400 miles away
D．they could easily be seen for the red colour
18．Which of the following is true?       .
A．Seientists have found why the animals can see their nests.
B．No one knows why the swallows can fly back to their familiar landmarks.
C．It’s very simple that the birds use sense of direction.
D．Many experiments have been made on how birds can fly their way home
19．Swallows like to spend ”our winter” in        .
A．England      B．London        C．Africa       D．Germany
20．When do the birds return from South Africa to England every year?
A．summer        B．spring        C．winter         D．Both A and B

Few people would question the value of taking part in sports for young people．With proper training，supervision，protective equipment and techniques，and an proper emphasis on winning，sports can develop a healthy body and spirit and a life-long interest in being active and fit .Without such measures，childhood sports can lead to injuries and even paralysis or death．
Even in the best conditions，no activity can be risk—free．But most serious hazards are preventable．Cyclists and football players can reduce their risks by wearing helmets；hockey players by wearing masks；basketball and tennis players by wearing eye guards；baseball players by wearing batting helmets．
Besides，risks to individual players can often be found，and thus prevented，through a properly performed medical exam before a child plays．For accidents that may not be preventable，having an emergency plan and first-aid equipment，and someone trained to use the equipment，can be lifesaving．
Still，each year，according to the American College of Sports Medicine，more than 775,000 children under 14 are treated in emergency rooms for sports injuries，nearly half of them preventable．An estimated 300,000 athletes experience exercise—related head illnesses each year，and almost all of them should have been avoided．
Further，from half to three—fourths of sports-related concussions（腦震蕩） are never even diagnosed；the injured are often sent back in to play too soon and put at risk of another more serious brain—damaging concussion．To help reduce these risks, the National Center for Sports Safety, with the National Athletic Trainers’ Association, offers a three-hour online safety course for coaches for $28 at www.SportsSafety.org.
1．Which of the following is true according to the passage?
A．All the accidents can be prevented．
B．All the accidents cannot be prevented．
C．Lives can be saved so long as there is proper equipment．
D．Lives cannot be saved even if there is proper equipment．
2．What does the underlined word “hazards”(in paragraph 2)mean?
A．mistakes          B．diseases           C．dangers            D．situations
3．It is implied in the passage that        ．
A．prevention of injuries is not paid enough attention to
B．children under 14 are more easily hurt in sports
C．most head illnesses are related with exercise
D．none of the head illnesses should have happened
4．What can coaches mainly learn from the online safety course?
A．How to cure brain-damaging concussion．
B．How to diagnose brain-damaging concussion．
C．How to predict the possibility of brain damage．
D．How to deal with the injured properly．

本文介紹了美國著名的生物學(xué)家Edward Wilson 的著作The Future of Life中的一些有關(guān)如何開發(fā)、利用和保護(hù)自然資源的情況。
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(資源). 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(生物多樣性)of our earth.
Wilson begins with an open letter to the pioneer in environment (環(huán)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(物種) 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.
小題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
小題2:How many species are most important to our present food supply?
A．Twenty.B．Eighty.C．One hundredD．Ten thousand.
小題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
小題4: We can infer that the text is _______
A．a(chǎn) description of natural resources
B．a(chǎn) research report
C．a(chǎn) book review
D．a(chǎn)n introduction to a scientist.

C
A gadget which makes water out of air could become the greatest househo1d invention since the microwave.
Using the same technology as a dehumidifier（除濕器），the Water Mill is able to create a ready supply of drinking water because it can always get it from an unlimited source—the air．
The company behind the machine says not only does it offer an alternative to bottled water in
developed countries, but it is a solution for the millions who face a daily water shortage．
The machine works by drawing in wet air through a filter（過濾器）and over a cooling instrument which changes it into water droplets．It can produce up to 1 2 liters a day．The Water Mill will also produce more water when storms pass over, as the amount of water which is contained in the air increases. In keeping with its eco-development, the machine uses the same amount of electricity as three lights.
Inventor Jonathan Ritchey said: “The demand for water is off the chart. So people are looking for freedom from water distribution systems that are shaky and unreliable.”
The machine, which is about 3 feet wide, is likely to cost ￡800 when it goes on sale here in the spring. Its maker, Canadian Firm Element Four, roughly calculates that a litre of water cost around 20p to produce.
Environmentalists state that half the world’s population will face water shortage because of climate change by 2080. One in five is said to lack access to safe drinking.
The Water Mill is not effective in areas where the amount of water contained in the air is below about 30 percent, but in Britain that won’t be much of a problem.
63．What does the underlined word “it” refer do?
A．Drinking water.       B．Invention. C．Microwave.      D．Water Mill.
64．What do we learn about the machine?
A．It works in the same way as microwaves.
B．It is very expensive for families to afford.
C．It absorbs steam and turns it into water.
D．It helps to make the water clean to drink.
65．What does the passage lead us to believe?
A．The cost of water will go up.  B．Bottled water will disappear sooner.
C．The machine is energy saving. D．The machine will be popular worldwide.
66．What’s the best title for the passage?
A．A New Way to Solve Water Problem.    B．A Machine to Make Water out of Air.
C．A Dehumidifier to Produce Water.     D．An Absolutely New Invention
