Researchers are placing robotic dogs (机器狗) in the homes of lonely old people to determine whether they can improve the quality of life for humans. Alan Beck, an expert in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study concerning the influence of robotic dogs on old people’s depression, physical activity, and life satisfaction. “No one will argue that an older person is better off being more active, challenged, or stimulated (刺激) ,” Edwards points out. “The problem is how we promote(使……成为现实)that, especially for those without friends or help. A robotic dog could be a solution.”
In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, researchers will collect baseline data for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the researchers will review the data to determine if it has inspired any changes in the life of its owner.
“I talk to him all the time, and he responds to my voice,” says a seventy-year-old lady.“When I’m watching TV, he’ll stay in my arms until he wants down. He has a mind of his own.”
The AIBOs respond to certain orders. The researchers say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.
“At the beginning, it was believed that no one would relate to the robotic dog, because it was metal and not furry,” Beck says. “But it’s amazing how quickly we have given up that belief.
“Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters’ blood pressure, oxygen levels, or heart rhythms. AIBOs may even one day have games that can help stimulate older people’s minds.”
48. The purpose of Beck and Edwards’ study is to ______
A. understand human-animal relationship       B. make lonely old people’s life better
C. find the causes of old people’s loneliness    D. promote the animal-assisted research
49. In the research, the old people are asked to ______
A. note the activities of AIBOs                      B. keep AIBOs at home for 12 weeks
C. record their feelings and activity               D. analyze the collected information
50. What is the advantage of AIBO over live dogs?
A. It is easier to keep at home.                      B. It can help the disabled people.
C. It responds to all the human orders.           D. It can watch TV with its owner.
51. The author seems to suggest that the future robotic dogs may ______
A. cure certain diseases                                B. keep old people active
C. change people’s beliefs                             D. look more like real dogs

Unlike modern animal scientists, dinosaur scientists cannot sit on a hillside and use telescopes to watch dinosaurs in order to know how they lived and whether they were good parents. Instead, they have to search hard for information from dinosaurs’fossils(恐龙化石) because dinosaurs died out millions of years ago.
It’s very difficult for the scientists to reach an agreement because different results can be got from the same fossils, Many fossils of the same kind of dinosaurs have been dug out from one place. They might have formed when an entire group of dinosaurs got stuck(陷入)all at once, or they might have been the result of dinosaurs getting stuck one after another over a course of a few centuries. Thus we can say that dinosaurs might have in the first case lived in big groups and in the second lived alone.
Though there are two different results, dinosaur scientists now generally agree that at least some kinds of dinosaurs lived in big groups. “That’s pretty much settled at this point.” Says Paul Sereno, A kind of dinosaurs called Sauropods left behind tracks in the western United States that appear to run north and south, suggesting that they even moved long distances together.
As to whether dinosaurs cared for their young, dinosaur scientists have turned to the closest living relatives of dinosaurs ― birds and crocodiles ― for possible models. Birds give a lot of care to their young, while crocodiles just help their young to the water. The discovered fossils of dinosaurs sitting on their eggs and staying with their young suggest the parents were taking care of their babies, but we still cannot say that all dinosaurs did the same.
There is still a long way to go before the above questions could be answered. Dinosaur scientists will have to find more proof to reach an agreement.
60.Dinosaur scientists can get information directly by           .
A.  studying dinosaur fossils                B. examining modern animals
C. watching dinosaurs                         D. using telescopes
61.What is pretty much settled according to Paul Sereno?
A. Half of the dinosaurs lived alone.    B. Most dinosaurs moved long distances.
C. Many dinosaurs settled in the north. D.Some dinosaurs lived in big groups.
62.Dinosaur scientists can probably know whether dinosaurs were good parents by              .
A. watching many kinds of animals      B. studying dinosaurs’living relatives
C. following the tracks left behind              D. working on dug-out dinosaur eggs
63.Which of the following the according to the paragraph?
A. Birds hardly ay attention to their young. B. Baby crocodiles can look after themselves well.
C. Some dinosaurs took care of their young.       D. Birds and crocodiles take good care of their young.

As skies are filled with millions of migrating(迁徙)birds, European scientists say the seasonal wonder appears to be strange: The fatter the bird, the better it flies.
The results of their study led to a theory opposite to a central one of aerodynamics(空气动力学), which says that the power needed to fly increases with weight.
For birds, obviously, the cost of flying with heavy fat is much smaller than we used to think. Researchers found that red knot wading birds double their normal body weight of 100 grams before making their twice-a-year nonstop flight between the British Isles and the Russian Arctic. Distance: 5, 000 kilometers.
Another study in the magazine Nature measured the advantage of flying in an aerodynamic group which allows birds to save energy by flying smoothly and quietly in the lead bird’s air stream.
Flying in groups, their heart rates were 14.5 percent lower than flying alone, according to Henri, a French scientist. The findings help explain how birds complete difficult migrations. Researchers had thought that thinner, stronger birds would have the best chance to survive.
The first study suggests that building up fat to be burnt as fuel during the migration is worth more than the energy it takes to carry the additional weight.
In the study, researchers said their team studied the birds flown at different body weights during 28 simulated(模拟的)flights. They forced a small amount of special water into the birds’ bodies so that they could measure the amount of energy burnt during the flight.
60.A red knot wading bird of 100 grams will probably weigh_____before making its nonstop migrating flight.
A.50 grams             B.100 grams           C.150 grams             D.200 grams
61.During their migrating flight, red knot wading birds can save energy by flying_______.
A.separately        B.alone            C.in groups               D.in pairs
62.A_______red not wading bird has a better chance to survive during its migrating flight.
A.stronger       B.weaker         C.thinner                  D.fatter
63.The best title for this passage may probably be________.
A.Birds Thin Down For Journey               B.Birds Fatten Up For Journey
C.How Birds Build Up Fat For Journey       D.How Birds Burn Energy For Journey

The coyote(丛林狼)that clever animal of wide-open spaces,has come to the nation’s captial.In fact ,coyotes have spread to every corner of the United States,changing their behaviors to fit new environments and causing researchers to deal with a troublesome new kind of creature:the city coyote.
The coyote originally lived in the middle of the continent.One of its most obvious characters is its smartness, which has made the animal a notorious（臭名昭著的）pest.Hunters trapped,shot and poisoned more than a million coyotes in the 1900s.It’s still one of America’s most hunted animals. Yet the coyote has survived.How has the coyote shown this extraordinary ability? “I guess if you wanted to use one word,it’d be ‘plasticity’. ”says Erie Gese,an expert at Utah State University. Coyotes can live alone, in pairs, or in large packs like wolves,hunt at night or during the day , occupy a small region or an area up to 40 square miles;and live on all sorts of food,from lizards（蜥蜴）and shoes, to ants and melons.
Unbelievably people helped coyotes increase when they killed most of the wolves in the United States. The spreading of coyotes into city areas,though.is recent.They travel at night,crossing sidewalks and bridges.running along roads and ducking into culverts （钻入涵洞）and underpassces .No one knows why coyotes are moving into cities, but experts explain that cleverer, more human-tolerant（不怕人的）coyotes are teaching urban survival skills to new generations.
Occasionally. coyotes might attack human beings. There have been about 160 attacks on people in recent years Therefore, people have been consistently told not to feed coyotes or leave pet food unsecured. That ,plus a large trapping program in the neighborhood, has cut down on the coyote population.
63.The underlined word “plasticity”in Paragraph 2 refers to____________.
A.the ability to fit the environment            B.notorious smartness
C.hunting ability                                     D.being human-tolerant
64.The aim of the passage is to_____________.
A.tell people how to fight against coyotes
B.tell us why the coyote is the most hunted animal
C.supply the reason why the coyote is a kind of motorious pest
D.explain how the coyote has spread to and survived in cities
65.According to the passage, coyotes__________.
A.originally lived in the west of the continent
B.sleep during the day but look for food at night
C.are teaching survival skills to their younger generations
D.suffered a population decrease because people killed wolves
66.According to the passage,to cut down on the coyote population, people are advised to_______.
A.leave pet food secured                          B.keep coyotes in small regions
C.force coyotes to live alone               D.avoid using trapping programs

The discovery of a dwarfed (矮个的)”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 (结构)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 enviromentD.reached Flores 40,000 years ago

An ichthyologist is a scientist who studies fish. Most people who do this job say they love their work because it is very rewarding and varied. They work not only inside a laboratory, but also out in the field. Fieldwork includes traveling to rivers, oceans and lakes in order to collect information and specimens（样本）, Reading, writing and speaking are also very important to the job. Fish scientists need to read the research of other scientists. They must he able to write up their own research clearly so that others can follow it. They also need to be able to give lectures about their findings, so that they can spread knowledge.
Ichthyologists who wish to specialize can choose any one of three areas of study. The first area is aquaculture (水产养殖). This involves the study and practice of fish farming and management. Because it is a rather new study, there are very few job opportunities available. However, as there is so much to discover, many see it as an exciting area for a new ichthyologist to enter. The second area is fisheries science, which means working with a team of scientists to find out more about different fish species. The third area is about the protection of natural fish populations. This is very important today, given that many fish species are in danger of dying out because of the actions of humans.
To become a successful fish scientist, you need to have a curious mind and be able to work on your own. You also need to be able to handle equipment and perform experiments; but most importantly, you must love fish. To become an ichthyologist, you will need to train at a university to pass a Bachelor of Science degree. For this, you will need to be good at mathematics, physical science and biology. Then, you will need to study for another year to complete an honours degree in ichthyology. This honours degree contains coursework about all aspects of fish. You also need to complete a research paper.
68. What makes the jobs of ichthyologists so varied?
A. They study fish habits and collect information.
B. They have to study science and mathematics.
C. They work in fields as well as in laboratories.
D. They read research papers written by others.
69. Which of the following statements is NOT true according to the passage?
A. An ichthyologist has an interesting and varied profession.
B. Aquaculture is the study of fish protection.
C. The life of an ichthyologist can involve lots of travel.
D. A fish scientist needs to be independent and curious about things.
70. Who is most likely to become an ichthyologist?
A. Tom, because he likes fishing and outdoor sports.
B. Jack, because he likes to travel and read adventure books.
C. Jenny, because she likes science, mathematics and reading about dinosaurs.
D. Jane, because she likes mathematics, science, biology and searching rock-pools.
71. The passage is probably written for         .
A. university students                        B. science researchers
C. fisheries experts                          D. fish farmers
