Scientists have uncovered the exact difference between man and mouse. Teams of scientists from around the world will publish today the draft(草图) genome(基因组) of the mouse, which enables them for the first time to compare another mammal’s entire DNA directly with that of a human.

The similarities are far greater than the difference－man and mouse share a comman ancestor that lived more than 70 million years ago－which has allowed scientists to find treatments for a good many human diseases.

British members of the project say the draft mouse genome, published in the journal Nature, has provided the “phrasebook” for scientists to translate the language of the human genome.

“The entire biomedical research community said for the first time fully using this resource to deal with human diseases. They will now have powerful tools that will serve them for many years to come,” said Dr. Jane Rogers, head of sequencing at the Welcome Trust Sanger Institute in Cambridge, which did 20 percent of the work.

Comparisons show almost every gene in the mouse has a corresponding(对应的) gene in humans－a 99 percent similarity that should help to find how each human gene works. Already the work has been able to show that man and mouse each have about 30,000 genes yet only 300 or so are unique to either species, increasing the value of the lab mouse as a “model” for human genetics.

This is an extraordinary milestone. For the first time we have an opportunity to see ourselves in an evolutionary(进化的) mirror. The mouse genome stands for a very important chapter in the lab notebook of evolution. By taking away genes to create sick mice, scientists have been able to reproduce a number disorders. Knowing the entire genomes of humans and mice will enable them to employ the technique more widely leading to a rapid development in the understanding of illnesses.

1．The importance of the discovery lies in the fact that __________.   

       A．man has finally found his true ancestor

       B．it will be easier for people to find the causes of human diseases and cure them

       C．it has enabled the scientists to compare human DNA with that of another mammal

       D．it makes it possible for man to understand the complicated language of his genome

2．The word “unique” in the fifth paragraph probably means ___________.

       A．having no like or equal                          B．the same

       C．corresponding                                     D．excellent

3．It can be inferred that _____________.

       A．almost every gene of a mouse works in the same way as that of a human being

       B．it has become easier for humans to find their real ancestor

       C．more mice will be used in scientific experiments

       D．scientists will use fewer mice in their experiments to protect them

4．Which of the following is the best title of the passage?

       A．Mouse “Book of Life” May Provide Cures for Human Diseases

       B．Mice and Men Are the Same

       C．Man and Mouse Share a Common Ancestor

       D．The Difference Between Man and Mouse

Many people think of guys as being carefree when it comes to their appearance. But in fact, a lot of guys spend plenty of time in front of the mirror. They care just as much as girls do about their body image.

    Body image is a person’s opinions and feelings about his or her own body and physical appearance.    You appreciate your body for its capabilities and accept its imperfections.

   Here are some ideas：

    Recognize your strengths. Different body types are good for different things. What does your body do well? Maybe your speed, strength, or coordination makes you better than others at a certain sport. That may be basketball, table tennis, mountain biking, dancing, or even running. Or perhaps you have non-sports skills, like drawing, painting, singing, playing a musical instrument, writing, or acting.     .

    Exercise regularly. Exercise can help you look good and feel good about yourself. Good physiques (体形) don’t just happen.    A healthy habit can be as simple as exercising 20 minutes to 1 hour three days a week. Working out can also lift your spirits.

    Respect your body! Practicing good habits—regular showering; taking care of your teeth, hair, and skin; wearing clean clothes, and so on—can help you build a positive body image.

         Your body is just one part of who you are. Your talent for comedy, a quick wit (智慧), and all the other things make you unique. So try not to let small imperfections take over. (256 words)

   A. Use this as an opportunity to discover what you’re good at.

   B. Be yourself.

   C. Having a positive body image means feeling satisfied with the way you look.

   D. Just explore talents that you feel good about.

   E. They take hard work, regular workouts, and a healthy diet.

 F. The good news is that self-image and body image can be changed.

   G. So, what can you do to develop a positive body image?

    There are going to be moments in life when you must make very important decisions. You will find many people   36   to offer you advice if you ask for it (and even if you don’t), but always remember that the life you   37   is yours and nobody else’s. It’s important to decide for yourself what’s important to you and what you want before you   38   others. Because while there will be times   39   outside advice proves wise, there will be at least as many times when it proves completely   40  . The only way to really evaluate other folks’ advice is to first learn everything that you can about whatever challenge you are   41  . Once you’ve done that, in most cases you should be able to make a wise decision   42   anyway.

You were   43   with the ability to decide what is and what isn’t in your best interest. Most of the time, you will make the right decision and   44   the appropriate actions, and in thinking for yourself, you will become far more successful than if you had gone

against your own   45  .

Early on in my investment career, I made the mistake of   46   a few important business decisions on colleagues’ opinions instead of conducting the   47   necessary to make a wise decision. It wasn’t due to   48   on my part; no one could ever accuse me of that. But, being   49   to Wall Street, I intended to assume that my more senior   50   knew more than I did, and so I   51   too much significance to their opinions.

You know what happened? Each of those investments ended in   52  . Eventually I stopped allowing myself to be influenced by   53   and began doing the work myself and making my own decisions. It took me until I was almost 30 years old to   54   this—it’s never too late for a person to change his approach both to   55   and to life.
