What will people die of 100 years from now? If you think that is a simple question, you have not been paying attention to the revolution that is taking place in bio-technology. With the help of new medicine, the human body will last a very long time. Death will come mainly from accidents, murder and war. Today’s leading killers, such as heart disease, cancer, and aging itself, will become distant memories.

In discussion of technological changes, the Internet gets most of the attention these days. But the change in medicine can be the real technological event of our times. How long can humans live? Human brains were known to decide the final death. Cells are the basic units of all living things, and until recently, scientists were sure that the life of cells could not go much beyond l20 years because the basic materials of cells, such as those of brain cells, would not last forever. But the upper limits will be broken by new medicine. Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs (The medicine, made up of the basic building materials of life, will build new brain cells, heart cells, and so on—in much the same way our bodies make new skin cells to take the place of old ones.

It is exciting to imaging that the advance in technology may be changing the most basic condition of human existence, but many technical problems still must be cleared up on the way to this wonderful future.

1. In the author’s opinion, today’s most important advance in technology lies in________.
A. medicine
B. the Internet
C. brain cells
D. human organ

2. Humans may live longer in the future because________.
A. heart disease will be far away from us
B. human brains can decide the final death
C. the basic materials of cells will last forever
D. human organs can be repaired by new medicine

3. We can learn from the passage that ______
A. human life will not last more than 120 years in the future
B. humans have to take medicine to build new skin cells now
C. much needs to be done before humans can have a longer life
D. we have already solved the technical problems in building new cells

参考译文：
100年后人类会因何而死呢？如果你认为这是一个简单的问题，说明你还没有注意到正在发生的生物技术革命。在新的药物的帮助下，人类身体将能活很长时间。事故，谋杀和战争将成为死亡的主要原因。当今的主要人类杀手，像是心脏病，癌症，以及人类自身的衰老，都会变成遥远的记忆。

谈到技术革新，网络现在受到最多的关注。但是医学的变革才是我们时代真正的技术变革。人类能活多久？众所周知，人类大脑决定了最终的死亡。细胞是所有生物的基本单位，直到最近，科学家们确定了由于构成细胞的基本材料，例如大脑细胞不能永远存活，细胞的生命不可能超过120年多少。但是新的药物打破了年龄的上限。在2050到2100之间的某个时间，医学将发展到这样的程度，即每10年左右，人类可以服药来修复自己的器官（这个药由基本的生命建造材料构成，将产生新的脑细胞，心脏细胞，等等——道理和我们身体新旧皮肤细胞更替差不多。

想象技术的发展可能会改变人类生存的大部分基本条件，这是多么激动人心，但是在这个精彩的未来实现的道路上依然有许多必须要解决的技术问题。

词汇及短语：
bio-technology: 生物技术
cell:细胞
clear up: 处理，完成
答案解析：
1.解析：A正确
作者认为当今最重要的技术发展是哪方面的？
But the change in medicine can be the real technological event of our times.这句中的but表示转折，前面一句说的是大众的观点，but后是作者的看法，强调了real，表示了对前一观点的否定，因此是医学方面的发展是最重要的

2.解析：D正确
人类未来也许可以活得更久是因为？
Sometime between 2050 and 2100, medicine will have advanced to the point at which every 10 years or so, people will be able to take medicine to repair their organs前面一句说到药物可以打破人类现在的年龄极限

3.解析：C正确
从文中我们可以了解到什么？
A.未来人类生命不能超过120岁。文中说的是现在而不是未来。
B.人类现在服药生出新的皮肤。这在文中没有提及，只说our bodies make new skin cells to take the place of old ones我们的身体生出新皮肤
D.我们已经解决了生成新细胞的技术问题。many technical problems still must be cleared up on the way to this wonderful future. 还有很多问题未解决。
C.在人类获得更长的生命以前还有许多要做的。
