One of the great advances in modern technology has been the invention of computers. They are already widely used in industry and in universities and the time may come when it will be possible for ordinary people to use them as well. Computers are capable of doing extremely complicated work in all branches of learning. They can solve the most complex mathematical problems or put thousands of unrelated facts in order. These machines can be put to varied uses. For instance, they can provide information on the best way to prevent traffic accidents, or they can count the number of times the word "and" has been used in the Bible. Because they work accurately and at high speed, they save research workers years of hard work. This whole process by which machines can be used to work for us has been called automation. In the future, automation may enable human beings to enjoy far more leisure than they do today. The coming of automation is bound to have important social consequences. Some time ago an expert on automation, Sir Leon Bagrit, pointed out that it was a mistake to believe that these machines could "think". There is no possibility that human beings will be "controlled by machines". Though computers are capable of learning from their mistakes and improving on their performance, they need detailed instructions from human beings in order to be able to operate. They can never, as it were, lead independent lives, or "rule the world" by making decisions of their own. Sir Leon said that in the future, computers would be developed which would be small enough to carry in the pocket. Ordinary people would then be able to use them to obtain valuable information. Computers could be plunged into a national network and be used like radios. For instance, people going on holiday could be informed about weather conditions; car drivers could be given alternative routes when there are traffic jams. It will also be possible to make tiny translating machines. This will enable people who do not share a common language to talk to each other without any difficulty or to read foreign publications, It is impossible to assess the importance of a machine of this sort, for many international misunderstandings are caused simply through our failure to understand each other. Computers will also be used in hospitals. By providing a machine with a patients symptoms, a doctor will be able to diagnose the nature of his illness. Similarly, machines could be used to keep a check on a patients health record and bring it up to date. Doctors will therefore have immediate access to a great many facts which will help them in their work. Book-keepers and accountants, too, could be relieved of dull clerical work, for the tedious task of compiling and checking lists of figures could be done entirely by machines. Computers are the most efficient servants man has ever had and there is no limit to the way they can be used to improve our lives. Questions:

According to the author, computers can be used in______.

A．mathematics

B．statistics

C．medical sciences

D．all of the above

One of the great mystery of modern biology is how 【M1】______

proteins—the strings of amino acids that are the substance

of all living things—fold into precise and complex shapes

when they created inside living cells. 【M2】______

Proteins snap into their predestined shape within

microseconds, but the multistep process by which they do

so is so complicated that this would take a powerful computer【M3】______

centuries to come up a model for how it is done. 【M4】______

Recently, however, some very smart chemists at

Stanford University and the University of Illinois borrowed

an idea from the SETI (Search for Extraterrestrial

Intelligence) project to find an alternate solution. 【M5】______

The SETl @ home project divvies out to 4 million PC

owners chunks of raw data from the giant Arecibo radio

telescope in Puerto Rico. Those PCs, in its idle moments, 【M6】______

filter this electronic noise for telltale signs of another civilization

in the cosmos, and then ship the results back to SETI. Folding

@ home, the brainchild of Stanford biophysics Professor

Vijay Pende, similar parcels out the protein folding 【M7】______

computations among 43,000 active PC-owning volunteers.

In Sunday's online version of the British journal Nature,

Pende reported success. The "distributed computing"

system has modeled how a man-made chain of 23 amino

acids called BBA5 snap into shape over the course of 6 【M8】______

microseconds matched the time it takes the protein to 【M9】______

form. and fold in the lab.

The PC network already is at work deciphering the

folding of real human proteins and may one day ravel 【M10】______

just what goes wrong in misshapen proteins believed

responsible for afflictions such as Creutzfeldt-Jakob and

Alzheimer's disease.
