Surrounding the earth was an unbroken canopy of clouds miles thick and made up mostly of water vapor. Rain falling toward the still-hot earth was heated to steam and rose to the clouds again. After many millions of years, as the earth continued to cool, its surface temperature fell below the boiling point of water. Rainwater could now remain on the earth, covering its whole surface except for the higher places on earth that had been formed from the lighter rock materials.
In 1970, scientists had pieced together evidence that the lighter rock materials had formed one huge continent by a vast ocean. Then, about 200 million years ago, the great continent began to break up, the pieces moving slowly apart.
The onrushing waters of the single huge ocean now entered and filled the spaces between the separating continents--and became the several oceans and seas we know today.
This passage mainly talks about ______.
A.the origin of the earth
B.the origin of the ocean
C.the history of the earth
D.the forming of the earth's crust
The Chinese have used a method called acupuncture(针炙) to perform. operations for about 4,000 years without putting the patient to sleep. This involves placing flexible needles into certain parts of the body. The needles are available in a number of stores in China and anyone may buy them.
To learn how to use the needles takes about one month of training. But to be skillful requires greater time. (79) The person who performs the acupuncture knows how to put in the needles so the needles themselves are not painful. This person also knows where to place the needles so the patient feels no pain in the area where the operation is to be performed. A particular operation might require 25 or more needles placed in various parts of the body. But now this operation requires only 3 or 4 needles.
Today, the Chinese doctors are trying to learn more about acupuncture. (80) They are trying to develop a convincing theory to explain how the needles work in preventing pain, or why a needle in the wrist, for example, Would prevent the pain in the area of the mouth.
A patient who needs an operation is given a choice between having acupuncture or having one of the chemicals used for putting him to sleep. It has been estimated that over half of the patients choose acupuncture because there is no sickness after the operation but the chemical may make the patient sick for a few hours or a day.
Acupuncture is ______.
A.a medical operation
B.a medical needle
C.a medical technique
D.a medical machine
In the early fifties, only eight or nine out of a hundred young men changed their jobs within the first three years with the company. In the past few years, almost thirty-five percent of the college-graduated work force changed jobs within the same period. These people want to intensify their management training. Since most jobs take only a year to a year and a half to master, in order to continue learning, they have to make a job change. Even company presidents tend to be seen as mobile specialists, staying with one company an average of only five years.
Company presidents in the United States today tend to be young men who begin their careers with educational backgrounds in engineering science, or business management. They have worked for a few years as technical specialists and quickly moved into higher management positions. Most of them were making $ 30 000 per year by the time they reached thirty. On an average, these men have only twenty years working experience at management level when they become company presidents. On the way to the top, they have an average of eleven promotions and seven city transfers.
Friendships remain casual and are usually derived from business contracts. Families of these career men have little time to put down roots in and become part of a community.
In the past, a few men attained high positions through family and social connections; today, high positions go to men who are mobile, and have good educational, backgrounds.
According to the passage, an increasing number of future company presidents might be ______.
A.people who have spent a number of years with one company
B.young people who do not want to move often, but are steady and dependable
C.people who have spent a long time concerned with community affairs
D.young people who have good education and are willing to move around
The differences between American English and British English are not very great. Written English is more or less the same in both Britain and America, though there are some spelling differences. For example, centre, licence, colour and travelled are spelt as center, license, color and traveled in American English. In America "cock, rubber, iii, holiday, lorry, post... "are called "rooster, eraser, sick, vacation, truck, mail..." But people from the two countries can still understand each other easily.
There are only a very small number of differences in grammar between American English and British English. The most important differences are in spoken English. For example, Americans pronounce "tomato" differently from English people.
You may wonder "Which is correct?" The answer is that it does not matter. You should speak either American English or British English. But do not try to speak both at the same time.
When was English only spoken in England?
A.About the 6th century.
B.Before the 17th century.
C.Before the 14th century.
D.Before the 15th century.
How can a single stamp be worth $ 16 800?
Any mistake made in the printing of a stamp raises its value to stamp collectors. A mistake on one inexpensive postage stamp has made the stamp worth a million and a half times its original value. The mistake was made more than a hundred years ago in the British colony (殖民地) of Mauritius, a small island in the Indian Ocean. In 1847 an order for stamps was sent to a London printer—Mauritius was to become the fourth country in the world to issue stamps. Before the order was filled and delivered, a ball was planned at Mauritius ' Government House, and stamps were needed to send out the invitations. A local printer was instructed to copy the design for the stamps. He accidentally marked the words " Post Office" instead of " Post Paid" on the several hundred stamps that he printed.
Today there are only twenty-six of these misprinted stamps left—fourteen One-Penny Orange-Reds and twelve Two-Penny Blues. Because of the Two-Penny Blue's rareness and age, collectors have paid as much as $ 16800 for it.
Mauritius is the name of______.
A.an island kingdom
B.a British colony
C.a province of India
D.a London printer
The course is divided up into two parts: class time for learning laws and regulations and driving time to practice driving. Each student is required to drive a total of six hours. The students are divided up into groups of four. The students and the instructor go out driving for two hour blocks of time. Thus, each student gets half an hour driving time per outing. Drivers Ed cars are unlike other cars in which they have two sets of brakes, one on the driver's side and one on the other side where the instructor sits. Thus, if the student driver should run into difficulties the instructor can take over.
After a student has passed the driver's education course and reached the appropriate age to drive (this age differs in every state but in most cases the person must be 16 years old), he must take his driver's test. The person must pass all three tests in order to be given a driver's license. If the person does well in his or her driver's education class, he or she will pass the test with flying colors and get a driver's license.
In America, the driver's course mentioned above______.
A.is considered as part of the advanced education
B.is given to anyone wanting to get a driver's license
C.is carried on after students graduate from high school
D.is offered to all the students of Grade 2 in high school
One day a lazy sailor on his ship pretended to be ill. He lay on his bunk(铺) and groaned as if he were very sick. The captain came to see him and was very pleased to have a patient to look after. He told the man to rest for a few days and made the other sailors do his work. Three days later another sailor pretended that he had something wrong with his chest. Once more the captain looked in his medical books and told the "sick" man to have a rest.
The other sailors were very angry because they had more work to do. The patients had the best food and laughed at their friends when the captain was not looking. At last the mate (船长副手) decided to cure the "sick" men. He mixed up some soap, soot(烟灰) , glue(胶水) and other unpleasant things. Then he obtained permission from the captain to give his medicine to the "sick" men. When they tasted the medicine, they really did feel ill. It was so horrible that one of the patients jumped out of his bunk, ran up on deck and climbed the highest place on the ship. He did not want any more medicine.
The mate told both of the men that they must take the medicine every half an hour, night and day. This soon cured them. They both said they felt better and wanted to start work again. The captain realized that the men tried to deceive him so he made them work very hard for the rest of the voyage.
The first sailor pretended to be ill because he wanted to______.
A.test the captain's knowledge of medicine
B.be free from work
C.have the best food on the ship
