There are two kinds of physical activity which require special training. The first demands exact careful movements of the muscles. This kind of activity must be strictly controlled because even a slight movement in the wrong direction will lead a mistake. To type quickly, for example, a person needs training; the slightest movement of a finger in the wrong direction may cause a spelling mistake. A dancer who has to dance on the point of her shoes or turn around on one foot must be trained for a long period of time before she can sense her own center and balance herself. You may have seen a girl walking on a rope across an empty space, which, too, requires a lot of practice.
The second kind of physical activity needs greater strength or extra effort. Most of us get tired if we try to run half a mile without stopping, but a specially-trained person can do this without much effort. Three years ago, some scientists carried out experiments, which produced meaningful and unexpected results. They wanted to find out whether a certain amount of physical exercise would injure those suffering from heart problems. They selected some male patients and trained them in continuous bicycle riding. They were surprised to find that the harmful effect of given amount of physical effort was actually less on the hearts of these trained patients than on those of the patients who were not similarly trained. This is important because it shows that regular physical exercise enables us to make better use of the oxygen we breathe in and that this training, in fact, reduces the amount of work our hearts do. Many tasks which are hard for untrained people are not hard at all for trained people.
The first kind of physical activity must be strictly controlled because _________.
A．a mistake in the wrong direction is dangerous to the fingers
B．a wrong movement in a direction will cause no mistakes
C．a movement in the wrong direction will cause a mistake
D．a slight movement of a finger will lead to a mistake
What must a dancer do before she can balance herself?
A．She must dance on the point of her shoes.
B．She must receive long-time training.
C．She must turn around on one foot.
D．She must perform again and again.
The experiments done by some scientists showed that ________.
A．some male patients were asked to ride bicycles regularly in the experiments
B．the physical exercise had more harmful effect on the hearts of the untrained patients
C．the physical exercise was harmless to the male patients with heart trouble
D．the physical exercise could be helpful for the patients to take in more oxygen
What would be the best title for this text?
A．Training Our Bodies B．Physical Activities
C．Movement Training D．Extra Body Effort

Centuries ago, man discovered that removing moisture from food helps to store it, and that the easiest way to do this is to expose the food to sun and wind.
All foods including water — cabbage and other leaf vegetables contains as much as 93% water, potatoes and other root vegetables 80%, lean (瘦的) meat 75% and fish, anything from 80% to 60%, depending on how fatty it is. If this water is removed, the activity of the bacteria which cause food to go bad is controlled.
Nowadays most foods are dried mechanically. The conventional method of such dehydration (脱水) is to put food in chambers (室) through which hot air is blown at temperature of about ll0'C at entry to about 43'C at exit. This is the usual method for drying such things as vegetables, minced meat, and fish.
Liquids such as milk, coffee, tea, soups and eggs may be dried by pouring them over a heated steel cylinder (圆筒), then put them into a chamber through which a current of hot air passes. In the first process, the dried material comes off the roller (滚筒) as a thin film which is then broken up into small, though still relatively flakes (薄片). In the second process it falls to the bottom of the chamber as small powder. Where recognizable pieces of meat and vegetables are required, as in soup, the ingredients (成分) are dried separately and then mixed.
Dried foods take up less room and weigh less than the same food packed in cans or
frozen, and they do not need to be stored in special conditions. For these reasons they
are invaluable to the climbers, explorers and soldiers in battle, who have little storage
space. They are also popular with housewives because it takes so little time to cook
them.
It can be inferred from the passage that ________.
A. the rattier fish contain as much water as the lean one
B. the rattier the fish is, the more water it may contain
C. a fatty fish holds less water than a lean one
D. the water content of fish has nothing to do with the content of their fat
The underlined word "conventional" in Paragraph 3 can most probably be replaced by _________.
A. particular B. scientific C. usual D. special
Which of the following statements is NOT true about drying food?
A. The removal of water in food helps prevent it from going rotten.
B. The open-air method of drying food has been known for hundreds of years.
C. In the course of dehydration, the temperature of hot current coming from entry to exit is gradually going up.
D. The process of drying liquids is much more complex than that of drying solid food.
The last paragraph mainly talks about __________.
A. the reason why housewives like dried food
B. the general convenience of dried food
C. the methods of storing food
D. the advantages of dried, canned and frozen food

Holmes’ Knowledge
His ignorance was as remarkable as his knowledge. Of contemporary literature, philosophy and politics he appeared to know next to nothing. Upon my quoting Thomas Carlyle, he inquired in the naivest（天真的；幼稚的）way who he might be and what he had done. My surprise reached a climax, however, when I found incidentally that he was ignorant of the Copernican Theory and of the composition of the Solar system.
“You appear to be astonished, ” Holmes said, smiling at my expression. “Now that I do know it I shall do my best to forget it. You see, I consider that a man’s brain originally is like a little empty attic, and you have to stock it with such furniture as you choose: A fool takes in all the lumber of every sort that he comes across, so that the knowledge which might be useful to him gets crowded out, or at best jumbled up with a lot of other things, so that he has difficulty in laying his hand upon it. It is a mistake to think that the little room has elastic walls and can distend to any extent. Depend upon it, there comes a time when for every addition of knowledge you forget something that you know before. It is of the highest importance, therefore, not to have useless facts elbowing out the useful ones.”
“But the Solar System! ” I protested.
“What the deuce is it to me?” he interrupted impatiently.
One morning, I picked up a magazine from the table and attempted to while away the time with it, while my companion munched silently at his toast. One of the articles had a pencil mark at the heading, and I naturally began to run my eye through it.
Its somewhat ambitious title was “The Book of Life, ” and it attempted to show how much an observant man might learn by an accurate and systematic examination of all that came in his way. It struck me as being a remarkable mixture of shrewdness and of absurdity. The reasoning was close and intense, but the deduction appeared to me to be far-fetched and exaggerated. The writer claimed by a momentary expression, a twitch of a muscle or a glance of an eye, to fathom a man’s inmost thought. Deceit, according to him, was impossibility in the case of one trained to observation and analysis. His conclusions were as infallible as so many propositions of Euclid. So startling would his results appear to the uninitiated that until they learned the processes by which he had arrived at them they might well consider him as a necromancer.
“From a drop of water, ”said the writer, “a logician could infer the possibility of an Atlantic. So all life is a great chain, the nature of which is known whenever we are shown a single link of it. Like all other arts, the science of Deduction and Analysis is one which can be acquired by long and patient study, nor is life long enough to allow any mortal to attain the highest possible perfection in it. ”
This smartly written piece of theory I could not accept until a succession of evidences justified it.
What is the author’s attitude toward Holmes?
A Praising. B Critical. C Ironical. D Distaste.
What way did the author take to stick out Holmes’ uniqueness?
A By deduction. B By explanation. C By contrast. D By analysis.
What was the Holmes’ idea about knowledge-learning?
A Learning what every body learned. B Learning what was useful to you.
C Learning whatever you came across. D Learning what was different to you.
What did the article mentioned in the passage talk about?
A One may master the way of reasoning through observation.
B One may become rather critical through observation and analysis.
C One may become rather sharp through observation and analysis.
D One may become practical through observation and analysis.

When I was a child, I often dreamed of the time when I could leave home and escape to the city. We lived on a farm, in the winter especially, we wear quite out off from the outside world. As soon as I left school, I packed my bags and moved to the capital. However, I soon discovered that my life has its, too.
One big disadvantage is money. It costs so much to go out, not to mention basics like food and housing. Another disadvantage is pollution. I suffer from asthma (哮喘), and the air is so that I am afraid to go outside. Then there is the problem of traveling round. Although I have a car, I seldom use it because of the traffic jams. One choice is to go by bicycle, but that can be quite dangerous.
Of course there are advantages. First, there is so much to do in the city, whatever you tastes in culture or entertainment. Besides, there are wonderful jobs and greater chances of moving to a more important job or position. Finally, if you like shopping, the variety of goods is very surprising --- and, what is more, shops are often only a short walk away.
Is life better then, in the city? Perhaps it is , when you are in your teens or twenties. However, as you get older, and especially if you have small children, the peace of the countryside may seem preferable. I certainly hope to move back there soon.
What was the writer always thinking about when he was a child?
A. Staying on the farm. B. Moving to the countryside.
C. Leaving home for the city. D. Running away from the school.
Which of the following is true about the writer?
A. He is very old now. B. He is in good health.

C. an interest in the outside world D. persuade the reader to live in the city
How is the passage mainly developed?
A. By inferring. B. By comparing. C. By listing examples. D. By giving explanations.
