As if there weren’t enough of them in the world already, scientists have succeeded in cloning flies. The alike fruit flies are the first insects ever cloned, says the Canadian team that created them. The question everyone asks is why anyone would want to clone flies in the first place. She hopes that the insects , which are very easy to experiment with , will help to adjust the cloning process in other animals and even in humans, where the technique is being researched to aid production of therapeutic (治療的) stem cells.

In cloning, the DNA-containing nucleus of an adult cell is injected into an egg whose own nucleus(細胞核) has been removed. At the moment, the majority of cloned mice, sheep and other animals die before birth. It is thought this is because the adult DNA is not properly ‘reprogrammed’.

Using flies, researchers might discover genes that are important for this reprogramming, and that have matches in other animals. That is because it is relatively easy in flies to knock out the function of a single gene and then attempt cloning with these cells, which will test whether that gene is important. If such genes are confirmed, then in theory cloned mammalian embryos(晶胚) might be grown in selected solutions that change the activity of those genes to improve the technique’s success rate. Although some groups have attempted to clone insects before, Lloyd says this is the first time it has been successful. The team used a slight difference on the standard cloning process: they transferred nuclei taken from embryos rather than fully-grown adult cells. They sucked several nuclei (pl)out of developing fly embryos, and injected them into a fertilized(已受精的) fly egg. From over 800 early attempts, they cloned five adult insects, the group reports in the journal Genetics.

When I succeeded in becoming a part-time employee of Nokia China last summer, many friends asked me how I survived the interview.

I once asked myself the same questions. Many of my peers also __1._ for the job, including some very competitive and intelligent students from famous universities.

But why did the interviewer pick me instead of them?

Finally, _2.__ pushed me to ask the interviewers after we became colleagues. The answer was that I appeared confident but humble, responsible and communicative. They evaluated people not just on their academic certificates, but on the base of their __3.__ and abilities. I happened to be the right person.

To be frank, I once felt __4.__ of being a student from an unknown college, and I think this may apply to some of you. I thought my future was ruined. It was only at the time of my successful interview that I finally understood the famous saying --- “You decide where you go.”

A wide range of skills is important these days. I used to work for Master Kong. My job was to cook instant noodles for customers. I had regarded it as a piece of cake, but I failed constantly. I had to cook the noodles for the right amount of time to make them __5.__ good. Moreover, the noodles could only remain in a plastic cup of five minutes, or the taste would be ruined.

This experience taught me never to look down on anything, and always remain humble.

I also __6.__ as a volunteer for a beach volleyball event. My job was to help foreign visitors experience the beach. I thought it would be very easy because my oral English was __7.__ good. But when I went to talk with a group of foreign guests, I suddenly realized that I did not know a single beach volleyball term. I was embarrassed.

After this, I read brochures in both Chinese and English every day to learn the terms for facilities and related words. This allowed me to deliver accurate __8.__ to foreigners, and I was happy to work responsibly.

After these experience, I’m more confident and I strongly believe that my fate is in my  __9.__. It has certainly helped me make a giant step closer to my dream of graduating with prospects for the future. I hope my advice will benefit you as well.

 

Cheating can happen in a lot of different ways. When people cheat, it’s not fair to other people, like the kids who studied for the test or who were the true winners of a game.

Many people like the action of cheating. It makes difficult things seem easy, like getting all the right answers on the test. But it doesn’t solve the problem of not knowing the material and it won’t help on the next test --- unless the person cheats again.

Some people lose respect for cheaters and think less of them. The cheaters themselves may feel bad because they know they are not really earning that good grade. And, if they get caught cheating, they will be in trouble at school, and maybe at home, too.

Some kids cheat because they’re busy or lazy and they want to get good grades without spending the time studying. Other kids might feel like they can’t pass the test without cheating. Even when there seems to be a “good reason” for cheating, cheating isn’t a good idea.

If you were sick or upset about something the night before and couldn’t study, it would be better to talk with the teacher about this. And if you don’t have enough time to study for a test because of swim practice, you need to talk with your parents about how to balance swimming and school. A kid who thinks cheating is the only way to pass a test needs to talk with the teacher and his or her parents so they can find some solutions together. Talking about these problems and working them out will feel better than cheating.（291 words）

1.Some students like cheating mainly because_________.

A．cheaters are often thought highly of

B．people show no respect for those who cheat

C．parents whose kids cheat are often in trouble

Some young Cambodians are learning a new sport — skateboarding. The country’s first skateboard park is located on the grounds of a local charity group at the edge of Phnom Penh, the capital.

Sports like Khmer boxing and soccer are wildly popular in Cambodia. But Chea, who has been skating for 6 months, says skating has already become his favorite sport.

The skaters are learning tricks like launching off a jump or half-pipe and flying through the air on their narrow wooden boards.

A non-governmental organization called Skateistan Cambodia organizes weekly programs at the park. Skateistan started its work in Afghanistan years ago. Rory Burke is working with the group which expanded to Cambodia last year.

Rory Burke points out, “Yeah, it’s definitely not a typical Cambodian pastime (消遣). And I think the idea of ‘why skateboarding’ is that it’s not been done before here. We want to use skateboarding as something saying, ‘Hey, this is new, this is something different.And that kind of itself becomes a little bit of hook. People see it and they think and they say, ‘Wow, what is that?’ and they want to get involved. ”

Skateistan partners with local groups that work with young people. The park is on the grounds of the group known as PSE, where children attend school and learn a trade. There are almost one hundred twenty participants. They all come from troubled lives.

Seventeen-year-old Sang Rotha is a student at PSE. “Sometimes I don’t do well in subjects like math,” he says, “I feel bad when I find it hard to keep up with my lessons. So that is why I skateboard ---to improve my bad feelings. ’，

He says he began skateboarding more than a year ago. Before he started training, it seemed very easy. But it was very difficult to learn tricks, and he got hurt a lot from falling off.

Rory Burke says learning to deal with the difficulties is part of the lesson for these young skateboarders.
