Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.
"I think we are knocking at the door of immortality(永生)," said Michael Zey, a Montclair State University business professor and author of two books on the future. "I think by 2075 we will see it and that’s a conservative estimate".
At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology（纳米技术）make it likely that humans will live in the future beyond what has been possible in the past. "There is a great push so that people can live from 120 to 180 years," he said. "Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years."
However, many scientists who specialize in ageing are doubtful about it and say the human body is just not designed to last about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.
Scientists also differ on what kind of life the super aged might live. "It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?" said Leonard Pooh, director of the University of Georgia Gerontology(老龄学) Center. "At present people who could get to that point are not in good health at all."By saying "we are knocking at the door of immortality", Michael Zey means ________.
| A．they believe that there is no limit of living |
| B．they are sure to find the truth about long living |
| C．they have got some ideas about living forever |
| D．they are able to make people live past the present life span |
Donald Louria's attitude towards long living is that ________.
| A．people can live from 120 to 180 years |
| B．it is still doubtful how long humans can live |
| C．the human body is designed to last about 120 years |
| D．it is possible for humans to live longer in the future |
The underlined "it"（paragraph 4）refers to ________.
| A．a great push |
| B．the idea of living beyond the present life span |
| C．the idea of living from 200 to 300 years |
| D．the conservative estimate |

NewYork Tuesday April 12—Dustin Hoffman fan Pamela Crack got the shock of her life when the movie star telephoned her as she was doing her housework.. Crack, 58, said she was “flabbergasted” when she picked up the phone and heard the star at the other end.
“It’s not every day you get a Hollywood superstar phoning you when you’re doing the housework,” Crack told The Sun, “It was a moment I’ll never forget.”
Hoffman was in the back of a London taxi driven by Crack’s husband, Dave, when he made the call after being told Pamela was a fan. Dave Crack later became the star of Hoffman’s speech at the Bafta award ceremony Sunday, where the 62-year-old American actor presented the Best Film award.
“He said to give him a mention,” Hoffman told the audience to a burst of laughter. “Cheers Dave.” Taxi driver Crack said the Hollywood star was a joy to drive from the moment he got into the taxi eating a cheese and tomato sandwich.

Some people can stay up all night and still get work done the next day. I’m not one of them. After a night without enough sleep, I feel bad-tempered. I have trouble remembering things. And all I want to do is go to bed.
How do you feel after you’ve stayed up late to finish schoolwork or the day after an overnight party? Scientists now say that your answers to these questions may depend on your genes.
New research suggests that a gene called “period 3” influences how well you function without sleep. The “period 3” gene comes in two forms: short and long. Everyone has two copies of the gene. So, you may have two longs, two shorts, or one of each. Your particular combination depends on what your parents passed on to you.
Scientists from the University of Surrey in England studied 24 people who had either two short or two long copies of “period 3”. Study participants (参与者) had to stay awake for 40 hours straight. Then, they took tests that measured how quickly they pushed a button when numbers flashed (闪过) on a screen and how well they could remember lists of numbers.
Results showed that the people with the short form of “period 3” performed much better on these tests than the people with the long form did. In both groups, people performed worst in the early morning.
After the first round of experiments, participants were finally allowed to sleep. People in the group that performed well on the tests (those with the short form of “period 3”) took about 18 minutes to nod off.
While people with the long “period 3” gene fell asleep in just 8 minutes. They also spent more time on deep sleep. That suggests that people with the long form of the gene need more and deeper sleep to keep their brains working in top form.
I think I must have the long form of “period 3”. What about you?The purpose of this passage might be ___________
| A． to tell us the importance of plenty of sleep. |
| B． to tell the result of a research on sleepy gene. |
| C． to inform the harm of lacking sleep. |
| D． to announce the sleeping rules of humans. |
What kind of people need less sleep according to the research?
| A． Those with two short copies of the gene. |
| B．Those with two long copies of the gene. |
| C．Those with one short and one long copy of the gene. |
| D．Those with three short copies of the gene. |
If one lacks enough sleep, one should avoid doing impo
rtant or dangerous things ___________.
| A．at noon | B．at night |
| C．in the afternoon | D．at dawn |
Why did the writer think he or she had the long form of “period 3”?
| A． Because the writer could remain energetic without enough sleep. |
| B．Because the writer could do things correctly at dawn. |
| C．Because the writer needed more sleep to keep energetic. |
| D．Because the writer recovered quickly after sleep. |
So you have been called for an interview－well done. Your effort has paid off. Now go to get the job. You will feel better at the interview if you show an understanding of the nature of the organization.
Ask someone who already does it or check it out with one of the advisers.
Ask a member of family or a friend to act as the employer and to give you a practice interview. Afterwards discuss how it went.
Think about how the employer would prefer to see your look. Remember most of the employers are over 30. It is not wise to buy new clothes
that will be worn for the first time at the interview. It’s best to wear a familiar dress.
Carelessness in any of these could cost you the job. Arrive at least 15 minutes ahead of time. This will give you a chance to have a look around，read the notice board and get the feel of the place. Being late at interviews produces a bad impression. The first impression the interviewer gets of you is formed as you walk through the door，so take a couple of deep breaths.
Be ready to shake hands if the interviewer offers.
Don’t take a seat until asked. Then sit comfortably.
Remember the interviewer’s name and use it from time to time.
Be ready for the question “Is there anything you want to ask？” Before the interview you should get ready for two or three such questions. Look on these not just as a chance to get information but as a means to leave a better impression. Asking can show knowledge and avoid asking about holidays， pension (养老金) and so on. You can check on these later when the hopedfor job is offered.
And if you fail，look upon the interview as an experience in itself. Learn from it.
We wish you good luck and good job hunting. To make a good impression on the interviewer, it is important for you __________.
| A．to walk through the door quickly |
| B．to be a little late for the interview |

Goats are amazing animals. They can survive just about anywhere. Altogether there are nine species of goats in the world.
Goats have more uses than you could ever imagine. Goat’s meat can be eaten and goat’s milk is becoming popular as a healthy choice to drink milk. Goat’s milk is easier to take in than cow’s milk and it is called universal milk as it can be used to bottle-feed most animals. In nutrition, it is also good. Goat’s skins are still used today to make gloves and other items of clothing. The initial reasons for domesticating (驯化) goats were to get goat’s hair, meat and milk. Goat’s skins were used up until the Middle Ages for making bottles to hold water and wine for people who were traveling or camping.
Just like sheep, goats are considered to be the first domesticated animal. The domestication process began over 10,000 years ago in a North Iranian town. A lot of people keep goats as pets nowadays.
Goats are easily trained and you can teach them to pull carts and walk on ropes. Goats are also known for escaping their pens(圈). If you have unsecured fencing, your goats will be interested in it and test it out and soon you will know where the openings are. Goats are also widely known for their ability to climb trees, although the tree generally has to be at a slight angle(角度).
If goats are raised correctly and trained from an early age, they never develop any bad habits. Goats will attack each other. However, if they’re corrected from an early age they never attack humans or other animals.The passage is written mainly .
