15、named Rico recognizes the names of about 200 objects，say researchers in Germany.The dog also appears to learn words for new objects as easily as a 3yearold child would.His wordlearning skill is as good as that of a parrot or chimpanzee (黑猩猩) In one experiment，the researchers took all 200 items that
16、Rico was supposed to know and divided them randomly (随意地 ) into 20 sets of 10 objects each.The dog waited with one of his owners in one room，while an experimenter put a set of 10 objects into another room.Then，the owner told the dog to fetch one of the items.The dog had to go to the other room and b
17、ring the object back.In four trials，Rico got 37 out of 40 commands right.Because the dog couldnt see anyone to get visual clues about what to bring back，the scientists concluded that he must understand the meanings of certain words.In another experiment，the scientists took one toy that Rico had neve
18、r seen before and put it in a room with seven toys whose names he already knew.The dogs owner then told him to fetch the object，using a word Rico had never heard.In 7 out of 10 trials，Rico picked the right object， suggesting that he figured out the answer by process of elimination.A month later，he r
19、emembered half of the new names，which further impressed the researchers.Rico is probably smarter than the average dog，the scientists say.For one thing，hes a border collie，a breed known for its mental abilities.In addition，the 9yearold dog has been trained to bring toys back by their names since he w
20、as 9 months old.Its hard to know if all dogs understand at least some of the words we say.Even if they do，they cant talk back.Still，it wouldnt hurt to sweettalk your pup every now and then.You might just get a big，wet kiss in return!36What does this passage mainly talk about?AA dogs amazing memory.B

22、 a dog has a good memoryDmake sure a dog is as clever as a chimpanzee38The underlined word in the third paragraph can be replaced by _.Aexclusion BsimilarityCdeduction Dcomparison39From the last paragraph，we can infer that _.Adogs cant understand all the words we sayBdogs cant talk back to their own
23、ersCbe careful about your words to your dog，or youll be bitten by itDbe kind to your dog，and youll get a kind returnBWith only about 1,000 pandas left in the world，China is trying to clone (克隆) the animal and save the endangered species.Thats more similar to what a Texas A & M University researchers
24、 have been undertaking for the past five years in a project called “Noahs Ark”Noahs Ark is aimed at collecting eggs，embryos (胚胎) ，semen and DNA of endangered animals and storing them in liquid nitrogen.If certain species should become extinct，Dr Duane Kraemer，a professor in Texas A & MS College of V
25、eterinary Medicine，says there would be enough of the basic building blocks to reintroduce the species in the future.It is estimated that as many as 2,000 species of mammals，birds and reptiles will become extinct in over 100 years.The panda，native only to China，is in danger of becoming extinct in the
26、 next 25 years.This week，Chinese scientists said they grew an embryo by introducing cells from a dead female panda into the egg cells of a Japanese white rabbit.They are now trying to implant(植入) the embryo into a host animal.The entire procedure could take from three to five years to complete.“The
27、nuclear transfer (核子移植) of one species to another is not easy，and the lack of available (capable of being used) panda eggs could be a major problem， ” Kraemer believes.“They will probably have to do several hundred transfers to result in one pregnancy (having a baby)It takes a long time and its diff
28、icult，but this could be groundbreaking science if it works.They are certainly not putting any live pandas at risk，so it is worth the effort.” adds Kraemer，who is one of the leaders of the Project at Texas A & M，the firstever attempt at cloning a dog.“They are trying to do something thats never been
29、done， and this is very similar to our work in Noahs Ark.Were both trying to save animals that face extinction.I certainly appreciate their effort and theres a lot we can learn from what they are attempting to do.Its a research that is very much needed.”40According to Professor Kraemer，the major prob
30、lem in cloning pandas would be the lack of _.Aavailable panda eggsBhost animalsCqualified researchersDenough money41The BEST title for the passage may be _.AChinas Success in Pandas CloningBThe First Cloned Panda in the WorldCExploring the Possibility to Clone PandasDChinathe Native Place of Pandas
31、Forever42From the passage we know that _.AKraemer and his team have succeeded in cloning a dogBscientists try to implant a pandas egg into a rabbitCKraemer will work with Chinese scientists in clone researchesDabout two thousand of species will probably die out in a centuryCYouve heard of fast food,
32、 but what about slow food?Slow food is an international movement.It promotes home cooking，and the use of fresh, unprocessed produce. It was founded as reaction to the popularity of unhealthy fast food.It also encourages people to buy food from local businesses, rather than large supermarkets.The mov
33、ement began in 1986. At that time, McDonalds wanted to open a restaurant in the centre of Rome (Italy). Food writer Carlo Perini，along with others, was against this. So, the Slow Food Organization was born. Today, it has over 100,000 members in 132 countries. And its symbol is one of the worlds slow
34、est moving creatures, the snail. The organizations website explains， “The snail was chosen because it moves slowly, and calmly eats its way through life.”But Slow Food isnt just about the food we eat. Its also about how we eat it. Slow foodies say that in our fastfood world with very little time, we
35、ve forgotten that eating should be a social activity. They believe families should eat together and talk, rather than watch TV with their dinner while sitting in front of it. In fact, research has shown that if children grow up in a family that eats together at the table, they are more likely to do
36、well in school, and less likely to have behavioral problems or develop eating disorders.And theres more! Slow Food has sparked an entire Slow Food Movement. This encourages people to slow down the pace of their busy lives. And now, within the movement, theres Slow Money, Slow Travel, Slow Parenting,
37、 Slow Art and Slow Media, among many others. In 1999 the World Institute of Slowness was formed.One of the Institutes slogans is a quotation by the famous American actress Mae West. She said， “Everything worth doing in life is worth doing slowly.”Do you agree? No need to answer straight away. Have a
38、 long hard thought about it. Take your time. And get back to us when you can.43If you are a member of the Slow Food Organization, you may _.Areact to fast food slowlyBbuy food from large supermarketsClike the animal of snailsDlike to cook at home44Why did people start the Slow Food Movement?ABecause
39、 food writers are against fast food restaurant everywhere.BBecause they have plenty of time to enjoy their dinner.CBecause they think eating should be an enjoyable family occasion.DBecause they want to slow down the development of society.45What can we infer from the text?ASlow Food Movement has lit
40、tle effect on the whole society.BChildren growing in slow food families usually behave well.CMae West thought that everything should be done slowly.DSlow foodies dont like to watch TV and other entertainment.46What is the authors purpose in writing this article?ATo call on people to join Slow Food M
41、ovement.BTo tell people what Slow Food Movement is about.CTo tell people to think about their life and their food.DTo call on people to object to fast food.DIt was a village in India.The people were poor. However，they were not unhappy. After all, their forefathers had lived in the same way for centu
42、ries.Then one day, some visitors from the city arrived.They told the villagers there were some people elsewhere who liked to eat frogs legs. However, they did not have enough frogs of their own，and so they wanted to buy frogs from other places.This seemed like money for nothing. There were millions
43、of frogs in the fields around, and they were no use to the villagers. All they had to do was catch them. Agreement was reached，and the children were sent into the fields to catch frogs.Every week a truck arrived to collect the catch and hand over the money. For the first time, the people were able t
44、o dream of a better future. But the dream didnt last long.The change was hardly noticed at first，but it seemed as if the crops were not doing so well. More worrying was that the children fell ill more often，and，there seemed to be more insects around lately.The villagers decided that they couldnt jus
45、t wait to see the crops failing and the children getting weak. They would have to use the money earned to buy pesticides (杀虫剂) and medicines. Soon there was no money left.Then the people realized what was happening. It was the frog.They hadnt been useless. They had been doing an important jobeating
46、insects. Now with so many frogs killed, the insects were increasing more rapidly. They were damaging the crops and spreading diseases.Now，the people are still poor. But in the evenings they sit in the village square and listen to sounds of insects and frogs.These sounds of the night now have a much
47、deeper meaning.47From Paragraph 1 we learn that the villagers _.Aworked very hard for centuriesBdreamed of having a better lifeCwere poor but somewhat contentDlived a different life from their forefathers48Why did the villagers agree to sell frogs?AThe frogs were easy money.BThey needed money to buy
48、 medicine.CThey wanted to please the visitors.DThe frogs made too much noise.49What might be the cause of the childrens sickness?AThe crops didnt do well.BThere were too many insects.CThe visitors brought in diseases.DThe pesticides were overused.50What can we infer from the last sentence of the text?AHappiness comes from peaceful life in the country.BHealth is more important than
