Go ahead，talk to your dog.
As many a dog owner will prove, our furry friends are listening. Now, for the doubters, there is scientific proof that they understand much of what they hear. A border collie called Rico can fetch at least 200 objects by name， researchers in Germany say. The dog also appears to learn words for new objects as easily as a 3-year-old child would. Its word-learning skill is as good as that of a parrot or chimpanzee.
In one experiment, the researchers took all 200 items that Rico is supposed to know and divided them randomly 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 bring the object back.
In four trials, Rico got 37 out of 40 commands right. Because the dog couldn't 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 never seen before and put it in a room with seven toys whose names he already knew. The dog's 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 remembered half of the new names, which further impressed the researchers.
Rico is probably smarter than the average dog, the scientists say. For one thing, he's a border collie, a breed known for its mental abilities. In addition, the 9-year-old dog has been trained to retrieve toys by their names since he was 9 months old.
It's hard to know if all dogs understand at least some of the words we say. Even if they do, they can't talk back. Still, it wouldn't hurt to sweet-talk your pup every now and then. You might just get a big, wet kiss in return!

B．Only a few dogs can talk back to its owner

51．Rico can do all the following except _____
A．understanding the meanings of certain words.

With only about 1, 000 pandas left in the world, China is desperately trying to clone(克隆) the animal and save the endangered species(物种). That’s a move similar to what a Texas A & M University researchers have been undertaking for the past five years in a project called “Noah’s Ark”.
Noah’s 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 & M’s College of Veterinary 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 reptiles will become extinct in over 100 years. The panda, native only to China, is in danger of becoming extinct in the 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 the embryo into a host animal.
The entire procedure could take from three to five years to complete.
“The 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 it’s difficult, 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 first-ever attempt at cloning a dog.
“They are trying to do something that’s never been done, and this is very similar to our work in Noah’s Ark. We’re both trying to save animals that face extinction. I certainly appreciate their effort and there’s a lot we can learn from what they are attempting to do. It’s a research that is very much needed.”
69. According to Professor Kraemer, the major problem in cloning pandas would be the lack of _______.
A. available panda eggs                     B. host animals
C. qualified researchers                     D. enough money
70. The best title for the passage may be _______.
A. China’s Success in Pandas Cloning   
B. The First Cloned Panda in the World
C. Exploring the Possibility to Clone Pandas
D. China —the Native Place of Pandas Forever
71. From the passage we know that _______.
A. Kraemer and his team have succeeded in cloning a dog
B. scientists try to implant a panda’s egg into a rabbit
C. Kraemer will work with Chinese scientists in clone researches
D. about two thousand of species will probably die out in a century

Two thieves came to a house to steal something. They dug a hole in the wall of the house.
There lived many mice in the house. The woman in the moonlight saw a mouse crawl(爬行) into the house. “Look! In comes one,” she said to the man in the house. He was so frightened that he hurriedly crawled out of the house and said to the one waiting outside, “She found me when I was just in.” But the thief outside didn’t believe him, so he said; “Let us two try to crawl into the house together.” At that time two mice happened to crawl into the house, too. The woman saw the mice and shouted, “In come two, catch them!” The two thieves were terribly frightened. The man in the house said, “You saw them come in but where are they? I will catch them tonight.” The two thieves started running away at once.

The man and the woman were ploughing in their fields. The rein(缰绳)broke and the woman came home for a rope. She saw two men selling sweet potatoes and wanted to buy some. She picked out two which looked like mice. At the time the man couldn’t wait for her any longer in the fields and he ran back from the fields to hurry her up.
