With only about 1,000 pandas left in the world, China is desperately trying to clone the animal and save these in a dangerous situation. 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 these 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 and reptiles will probably 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, but the lack of available 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. The cooperation between us is very much needed."

A young woman carrying a three-year-old child got on a bus. The conductor hurried to give her a warm welcome and then kindly asked the other passengers to make more room for the woman and her child. On seeing this, people began to talk. “You know this conductor used to be very rude. Now suddenly he has changed his bad behavior,” said a middle-aged man.
“Yes, he should be praised and we must write a letter to the company,” said a second passenger. “That’s right,” another lady said, “I wish a newspaper reporter were here so that more people could learn from this conductor.”
Just then a gentleman who looked like a teacher turned to the conductor and said, “Excuse me, but can I know your name, please? Your excellent service must be praised...”

When a cat is frightened, its heart starts beating faster, its muscles get tense, and there are changes in the chemicals in its blood stream. If the danger continues, it will defend itself, or it will run away as fast as possible.
Something like this also happens to people. When we are excited, angry, scared or aroused by other emotions, our bodies go through many physical changes, all of which make us more alert and ready to react. We, too, get ready to defend ourselves or run.Human beings, however, have a problem that animals never face. If we give way to our feelings and let them take over, we can get into trouble. Have you ever said something in anger ― or hit somebody - and regretted it later? Have you ever shouted at a teacher, told somebody you were lonely, or said you were in love, and then wished later you had kept your mouth shut? It isn’t always wise to express your feelings freely.
Does this mean that it’s smarter always to hide our feelings? No! If you keep the feelings of anger, sadness, and bitterness hidden away or bottled up inside, your body stays tense. Physicalillnesses can develop, and you can feel disturbed badly inside.It can actual1y be bad for your health.
Feelings that you keep all bottled up inside don’t just go away. It’s as if you bought some bananas and stuck them in a cupboard. You might not be able to see them, butbefore long you’d smell them. And if you opened the cupboard, chances are that you’d see little fruit flies hovering all over them. They’d be rotten.
You can try to treat emotions as if they were bananas in the cupboard. You can hide them and you can pretend they don’t exist, but they’ll still be around. And at last you’ll have to deal with them, just like those bananas.
72. By taking a cat as an example, the author wants to show us that .

A. we are not as alert as animals
B. we sometimes can’t control our feelings
C. we always do something wrong to other people
D. we don’t pay attention to our physical changes
74. The author wants to tell us in the last two paragraphs that .
A. we won’t be able to completely get away from our feelings .
B. we should treat emotions like bananas in a cupboard
C. feelings will gradually disappear when we hold them in
D. it’s good for our health to keep pleasant feelings
75. What would be the best title for the passage?
A. Frightened Cats and Human Beings
B. Feelings and Bananas
C. Deal with Feelings Wisely
D. Express Feelings Freely
These days, if you still think the cell phone is just for talking, you’ll get laughed at. Yes, it’s true, voice-only handsets have become out of date. Today’s do-it-all mobiles have a lot in common with the computer. The only difference may be that they fit in your pocket and you pay by the minute to use them. Some of the things a cell phone can do for you will be available this year:
Surf at speed
Cell phones that let you use the Web have been around for years. So, what’s new? Well, faster third-generation (3G) networks that let you surf at anywhere. This then allows a carrier to send video, music, and games to your phone. Possible choices are from LG Electronics VX 8000 and Motorola V1150.
Listen as you go
The problem with most cell phone MP3 players is that they hold only a handful of songs. But, that’s about to change. Sony Ericsson’s new W800i can hold around 150 songs in its 500 MB memory. And Samsung’s SPH-V5400 even comes with a 1.5 GB hard drive. Mobile phones may eventually replace mini-MP3 players, especially for teens.
Say cheese
Camera cell phones are not new either. But, most of them have limitations: around 1-megapixel (百万像素). But new technology has made 2-megapixel units more common, and 3-megapixel units are showing up soon. Some 2-megapixel models, like Sony Ericsson’s K750i, offer limited zoom and focus controls. Others, like LG’s recent A7110, can even capture 30 minutes of full-motion video.
Portable TV
You say you like “watching TV”? That’s what Samsung MM-A700 wants to give you. The new model lets users watch popular TV programmes — for a fee. Other choices are Nokia’s 6620, Sanyo’s MM7400 and NEC’s N940. The NEC model lets you watch public TV — no fee.
The above are just a handful of what you’ll see in the coming months. Further down the road, your mobile phone may play a host of other roles, such as mobile credit card, position locator ... So what is there that a cell phone can’t do?
68. Which of the following models should you choose to listen to the music?
A. Samsung’s SPH-V5400 and Nokia’s 6620.
B. Sony Ericsson’s W800i and Samsung’s SPH-V5400.
C. Sony Ericsson’s W800i and NEC’s N940.
D. Sanyo’s MM7400 and NEC’s N940.
69. What’s the difference between NEC’s N940 and other models?
A. It allows you to surf the Internet at a high speed.
B. It can capture 30 minutes of full-motion video.
C. It can hold as many as 150 songs.
D. It lets you watch public TV for free.
70. Which of the following statements is TRUE according to the passage?
A. All the functions of the models mentioned in the passage are completely new.
B. Camera cellphones of 3-megapixel units will appear soon.

B. an advertisement trying to persuade you to buy new cellphones
C. a science fiction trying to attract readers’ attention
D. a survey to find the development of cellphones

It is sometimes said that the English are polite people. This can make life difficult for foreigners. Suppose a foreign boy asks an English girl to go out with him and she says, “If I finish my work, I’ll meet you in the cafe at 7 o’clock.” Is she saying “yes” or “no” to his invitation?
In grammatical terms, she is using the conditional structure (表示条件的句式). By using the conditional, speakers of English can avoid giving a “yes” or “no” answer to a question. It enables people to be diplomatic (婉转的). If the girl doesn’t want to go out with the boy, she won’t turn up at the cafe. She will let him understand she is still working. If she wants to go out with him, but doesn’t want to appear too easy to catch, she has achieved that with her reply. But in this case, as she uses the first conditional which shows probability, she is quite likely to turn up at the cafe. Being polite can make life very difficult!
The conditional is often used by people in the news -- politicians, for example -- who wish to avoid speaking out their ideas. This is very important if they are on their way to discuss an agreement. No one wants to give away his or her points before he or she starts. A government spokesman might say to a group of workers, “If we could pay you more, we would.” The use of the conditional here makes room for argument although the speaker is using the second conditional form, which shows improbability. So it is unlikely the workers will get their rise.
“If ” is a small word, which appears often in the English language. It can show politeness, reported speech and conditionals such as the First -- probability -- if I can come to your party, I will; the Second -- improbability -- if I saw you tomorrow, I’d give you the book; and the Third -- impossibility (meaning it is too late to change something that has happened ) -- if you have told me, I would have helped you.
60. The using of the conditional can make a speech _________.
A. clearer B. quicker C. more polite D.more exciting
61. Which of the following is true according to the passage?
A. Language used in the news should make room to argue.
B. Usually English girls are not easy to catch.
C. English people never speak out their ideas in public.
D. The word “ if ” can show different meanings.
62. In the passage, “If we could pay you more, we would.” probably means __________.
A. the workers will make more money
B. the spokesman doesn’t give any promise
C. the spokesman keeps his word
D. the workers’ problems aren’t difficult
63. This passage is mainly talking about _________.
A. the conditional in communication
B. how to invite a girl in Britain
C. British people and their life
D. some language points in daily English
