 Our school has now started an activity called “Building Civilized Classes and a Harmonious Campus”. The topic is “Getting Rid of Bad Habits and Greet Civilization”.

Dear Mr. Johnson,

I’ve learned from a newspaper that some clerks are wanting in your company. I am eager to being one of them. So I am writing the letter. My name is zhang Hua. I

was born in the Hebei Province  and I am in good health. I’ve just graduated in the Computer Department of Wuhan University. I did very good in all subjects and I am special good at computer studies and English. I can read science books in English and doing some writing in English as well. Beside, I know a little French. And in my spare time ,I enjoy playing basketball. As is said that your company is very famous and I’ll very glad if you let me work for it. My telephone number is 027-89276628. I am looking forward to hearing from you soon.

Weight loss is a hard topic. Lots of people aren’t satisfied with their present weight, but most people aren’t sure how to change it. You may want to look like the models or actors in magazines or on TV, but those goals might not be healthy or realistic(现实的) for you .___71__

So what should you do about your weight control?

72  The best way to find out if you are at a healthy weight or if you need to lose or gain weight is to talk to a doctor or dietitian（营养学家).___73____If it turns out that you can benefit from weight loss then you can follow a few of the simple suggestions listed below to get started.

__74___People who lose weight quickly by crash dieting or other extreme measures usually gain back all of the pounds they lost, because they haven’t permanently(永久地) changed their habits. Therefore, the best weight management

ways are those that you can maintain for a lifetime.

Small changes are a lot easier to stick with(坚持做) than large ones. Try reducing the size of what you eat.__75___ Once you have that down, start gradually introducing healthier foods and exercise into your life

It’s a good idea to maintain a healthy weight because it’s just that: healthy.

A.      Try giving up regular soda for a week

B.      Try to pay attention as you eat and stop when you’re full.

C.      Weight management is about long-term success.

D.     Besides, no magical diet will make you look like someone else.

E.      Being healthy is really about being at a weight that is right for you.

F.      Changing from whole to nonfat or low-fat milk is also a good idea.

G.     They will compare your weight with healthy standards and help you set goals.

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 (治疗的) stem cells.

In cloning, the DNA-containing nucleus of an adult cell is injected into an egg whose own nucleus(细胞核) 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.

     C. they can gain some experience before cloning other animals

     D. it is safe to cline flies

69. The failure of most cloned animals is due to _______.

   A. the difference of other animals’ genes

   B. the improper technique of clone

   C. the complex of other animals

   D. the improper rearrange of the adult gene

70. It can be inferred from the last paragraph that ______.

     A. the clone of insects before used grown-up cells

  B. the clone of insects were never experimented before  

C. this time scientists cloned flies successfully and easily

      D. based on this success, other animals will be cloned in large quantities.
