After a busy day of work and play, the body needs to rest. Sleep is necessary for good health. During this time, the body recovers from the activities of the previous day. The rest that you get while sleeping enables your body to prepare itself for the next day.
There are four levels of sleep, each being a little deeper than the one before. As you sleep, your muscles relax little by little. Your heart beats more slowly, and your brain slows down. After you reach the fourth level, your body shifts back and forth from one level of sleep to the other.
Although your mind slows down, from time to time you will dream. Scientists who study sleep state that when dreaming occurs, your eyeballs begin to move more quickly (although your eyelids are closed). This stage of sleep is called REM, which stands for rapid eye movement
If you have trouble falling asleep, some people recommend breathing very slowly and very deeply. Other people believe that drinking warm milk will help make you drowsy. There is also an old suggestion that counting sheep will put you to sleep!

In ancient times the most important examinations were spoken, not written. In the schools of ancient Greece and Rome, testing usually consisted of saying poetry aloud or giving speeches.
In the European universities of the Middle Ages, students who were working for advanced degrees had to discuss questions in their field of study with people who had made a special study of the subject. This custom exists today as part of the process of testing candidates for the doctor's degree.
Generally, however, modern examinations are written. The written examination, where all students are tested on the same question, was probably not known until the nineteenth century. Perhaps it came into existence with the great increase in population and the development of modern industry. A room full of candidates for a state examination, timed exactly by electric clocks and carefully watched over by managers, resembles a group of workers at an automobile factory. Generally, during examinations teachers and students are expected to act like machines.
One type of test is sometimes called an "objective" test. It is intended to deal with facts, not personal opinions. To make up an objective test the teacher writes a series of questions, each of which has only one correct answer. Along with each question the teacher writes the correct answer and also three statements that look like correct answers to students who have not learned the material properly.
1. In the Middle Ages students ______.
A. took objective tests
B. specialized in one subject
C. were timed by electric clocks

A. personal
B. spoken
C. objective
D. written
参考答案：C
4. Modern industry must have developed ______.
A. before the Middle Ages
B. around the 19th century
C. in Greece or Rome
D. machines to take tests

Is teaching important? Well, of course it is. There was a time when the necessary knowledge could be taught to the young by family members. But as societies became more complex and division of labor more common, it was impossible for family members to teach the information and skills young people needed to become useful members of the society. As the need for specialists appeared, the job of teaching came into being in our country, and teaching as a job has been of increasing importance over the past hundred years. Today, we have strict rules for teachers. We hope all children can attend schools. Many things tell us that teaching is indeed an "important" job.
In recent years, there has been an increasing need for teachers to be "responsible". This means that the public expects teachers to succeed in teaching important information to the young. Teachers' salaries today, while not much, certainly are much higher than they were in years past. These increases have come about because people have realized that without enough salaries, people who have abilities will not become teachers. Today almost no one says that "anybody will do" for a teacher. The public expects "quality people" to teach the young, and progress is being made to give salaries that will make people who have abilities become teachers.

Israeli researchers said they had identified a naturally produced compound that may explain why only some smokers get lung cancer.
Researchers found that smokers with low levels of the enzyme were five to 10 times more likely to develop lung cancer than smokers with the highest levels.
The enzyme fixes damage done to DNA by smoking and other environmental stresses and is one of a large group of repair compounds in the body.
Writing in the Journal of the National Cancer Institute, Zvi Livneh and his colleagues said 40 per cent of the 68 lung cancer patients they tested had low levels of enzyme activity, in contrast to 4 per cent of a healthy group of 68 people.
Non-smokers with the lowest levels of enzyme also had a higher risk of lung cancer, although their overall risk of cancer was much lower than that of the smokers.
Lung cancer is by far the biggest cancer killer in the world, killing a million people every year worldwide.
Smoking is also a major cause of heart disease and stroke. The researchers said the findings needed to be confirmed in larger studies but they may lead to the development of a blood test that smokers could take to determine their personal risk. 209
