Hello, everyone,

Now I’ll tell you something about our research project The World Food Crisis on behalf of our group. As you know,…

A: Excuse me. Do you (76) r            me? I just had lunch here a half hour ago.

B: Of course I do.

A: I think I (77) I         my wallet here. Did you see it anywhere?…It’s not there. And not on the floor. Has anyone (78) s           at this table since we were away?

B: No. It’s been (79) e             the whole time.

A: Hmm. I don’t know how it could have (80) h             .

B: I remember, sir, that your friend took the bill. You didn’t (81) p          for the lunch yourself, did you?

A: No. My friend did.

B: Then are you sure you took your wallet out of your pocket (82) w         you were here?

A: No, I’m not sure. But I usually take out my wallet when I sit down. It’s not (83) c      to sit on it. So I usually put it next to me on the table.

B: Maybe you lost it before you came here. Or maybe you (84) I         it at home.

A: I don’t think it’s at home. I think I had it when I was here. But what should I do? Should I call the (85) p           ?

B: You can if you want. But they usually don’t do anything about lost wallets.

High school dropouts earn an average of $ 9,000 less per year than graduates. Now a new study dispels a common belief why they quit. It’s much more basic than flunking out（不及格）.

   Society tends to think of high school dropouts as kids who just can’t cut it. They are lazy，and perhaps not too bright．So researchers were surprised when they asked more than 450 kids who quit school about why they left.

   “The vast majority actually had passing grades and they were confident that they could have graduated from high school.” John Bridgeland, the executive researcher said. About 1 million teens leave school each year. Only about half of African-American and Hispanic（美籍西班牙的）student will receive a diploma（證書），and actually all dropouts come to regret their decision. So，if failing grades don’t explain why these kids quit, what does? Again，John Bridgeland："The most dependable finding was that they were bored.” “They found classes uninteresting; they weren’t inspired or motivated. They didn’t see any direct connection between what they were learning in the classroom to their own lives, or to their career aspirations.”

   The study found that most teens who do drop out wait until they turn sixteen, which happens to be the age at which most states allow students to quit. In the US，only one state，New Mexico，has a law requiring teenagers to stay in high school until they graduate. Only four states: California, Tennessee, Texas and Utah, plus the District of Columbia, require school attendance until age 18, no exceptions, another researcher，says raising the compulsory（義務(wù)的）attendance age may be one way to keep more kids in school．

   “As these dropouts look back，they realize they’ve made a mistake. And anything that sort of gives these people an extra push to stick it out and it through to the end, is probably helpful measure.”

   New Hampshire may be the next state to raise its school attendance age to 18. But critics say that forcing the students unwilling to continue their studies to stay in school misses the point－the need for reform. It's been called for to reinvent high school education to make it more challenging and relevant, and to ensure that kids who do stick it out receive a diploma that actually means something.

With only about 1, 000 pandas left in the world, China is desperately trying to clone the animal and save the endangered species.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 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.”

67. The aim of “Noah’s Ark” project is to _______.

A. make efforts to clone the endangered pandas

B. save endangered animals from dying out

C. collect DNA of endangered animals to study

D. transfer the nuclear of one animal to another

68. 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

69.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

70.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
