传统的动物资源保护措施主要是划定保护区或建立保种基础。这些措施能很好地保护物种的多样性,但也存在一些缺点:保护区面积大,偷猎现象屡禁不止;建立良种基地保护地方品种投资大,时间长,容易出现近亲繁殖、物种衰退等现象。试管、克隆、冷冻保存等生物技术新成果的问世,为动物遗传资源的保护和利用开辟了新途径,建造“动物诺亚方舟”不再是天方夜谭。这段文字主要介绍了( )

A.保护动物物种多样性所取得的突破性进展

B.动物资源保护促成了生物技术新成果的诞生

C.生物技术的进步为动物资源保护开辟了新天地

D.传统资源保护措施所遇到的困难和取得的进步

答案

参考答案:C

解析:【解析】C。解答此题的关键是“试管、克隆、冷冻保存等生物技术新成果的问世,为动物遗传资源的保护和利用开辟了新途径”这句。A项不够具体,B项不能从文中推出,D项未突出生物新技术。

     My house is made of wood, glass and stone. It is also made of software (软件).

     If you come to visit, you'll probably be surprised when you come in. Someone will give you an

electronic PIN (个人身份证号码) to wear. This PIN tells the house who and where you are. The

house uses this information to give you what you need. When it's dark outside , the PIN turns on the

lights nearest you , and then turns them off as you walk away from them. Music moves with you too.

If the house knows your favorite music , it plays it. The music seems to be everywhere, but in fact other

people in the house hear different music or no music. If you get a telephone call , only the nearest

telephone rings.

    Of course, you are also able to tell the house if you want something. There is a home control

console (控制台), a small machine that turns things on and off around you.

    The PIN and the console are new ideas, but they are in fact like many things we have today. If you

want to go to a movie,you need a ticket. If I give you my car keys,you can use my car. The car works

for you because you have the keys. My house works for you because you wear the PIN or hold the

console.

    I believe that ten years later, most new homes will have the systems (系统) that I've put in  my house.

The systems will probably be even bigger and better than the ones I've put in today.

I like to try new ideas. I know that some of my ideas will work better than others. But I hope that one

day I will stop thinking of these systems as new, and ask myself instead,"How did I live without

them?"
