听力原文： How do the birds manage to find their way？ There seems to be no single answer: they use many methods. Some we are beginning to understand; and there may be some that depend on abilities we have not yet suspected. Many birds certainly follow major geographical features. Migrants follow recognized land, fly over familiar sea and arrive at their summer homes.
But all birds cannot use such straightforward methods. An Arctic sea bird, for example, has to fly at least 3,000 kilometers across the Antarctic Ocean with no land to guide it. We know that some birds flying at night, navigate by the star for on cloudy nights they tend to get lost.
Day-flying birds may use the sun. If they are to do so, they must have a precise sense of time. Still others appear to be able to use the earth' s magnetic field as a guide. So it seems that many migrating birds must carry in their brains a clock, a compass and the memory of a map.

Many Older Doctors Plan to Phase out Their Practice
The results of a new survey indicate that 48 percent of physicians between 50 and 65 years of age are planning to reduce or end their clinical practice in the next 1 to 3 years. The findings also suggest that many older physicians believe that their younger counterparts do not have the work ethic they do.
The survey, which was conducted by Merritt Hawkins & Associates, a Texas-based physician search and consulting firm, suggests that many older physicians are simply unhappy with the changes that have taken place in medicine over the years.
"When Baby Boom doctors entered medicine they had control over how they practiced and the fee they charged But the rules changed on them in mid-stream and now many are looking for a ticket out," Mark Smith, executive vice president of Merritt Hawkins & Associates, said in a statement.
"Our study is the only one I am aware of that examines the career plans of physicians in the 50-to-65 age group." This age group represents more than one-third of all physicians in the U. S. If they stop working in the coming years, it will have a "significant impact" on the overall supply of physicians, Smith told Reuters Health.
The results of the survey, which included 1,170 respondents (调查对象), show that 24 percent of older physicians are planning to leave clinical practice all together in the next 1 to 3 years. Specifically, 14 percent said they were planning on retiring, 7 percent said they were looking for a medical job in a non-patient care setting, and 3 percent said they were seeking a job in a non-medical field.
For those physicians not leaving clinical practice, many said they would make changes to reduce the number of patients they treat. For instance, 12 percent said they would begin working part-time, 8 percent said they planned to stop taking new patients or markedly reduce their patient load, and 4 percent expressed a desire to work on a temporary basis.
When asked about the work ethic of physicians entering practice today, 68 percent of the respondents said that these younger doctors are not as dedicated or as hard working as physicians who entered practice 20 to 30 years ago.
Fifty-seven percent of older physicians said they would not recommend medicine as a career to their own children. Similarly, 44 percent said they would not select medicine as a career if they were starting out today.
"The most ominous (不祥的) finding is that about one half of physicians surveyed plan to either abandon patient care in the next 1 to 3 years, or significantly reduce the number of patients they see," Smith said "The U. S. already is facing a widespread shortage of physicians. Should older, 'workhorse' physicians choose to opt out of patient care, access to medical services will be further restricted."
Which is NOT true of physicians in the 50-to-65 age group in the U. S.？
A．They are mostly baby boomers.
B．They have nothing to complain about.
C．Many of them plan to gradually stop their practice.
D．They account for over one-third of all physicians in the country.
"To reduce pain, take two tablets with water, followed by one tablet every eight hours, as required For nighttime and early morning relief(缓解疼痛) take two tablets at bedtime. Do not take more than six tablets in twenty-four hours. For children six to twelve years old, give half the amount. For children under six years old, ask your doctor's advice.
Reduce the amount if you suffer from restlessness or sleeplessness after taking the medicine."
How many tablets at most can a person over 12 have in 24 hours？
A．Three.
B．Four.
C．Six.
D．Eight.
This is migration. There are many things which help animals to migrate. Birds and other animals have a body clock which tells them about changes in temperature and periods of light. Birds and some insects use their eyes to measure and compare the position of the sun from different place.
Many people now believe magnetism is very important. The earth itself is a magnet and every kind of life is affected in some way by its magnetic, fields.
But there are still many questions without answers, for example, the migration of eels. European eels travel down their rivers and into the Atlantic Ocean. They then swim 5600 kilometers to the Sargasso Sea, where they lay their eggs. The eels then die. The baby eels are carried by the Gulf Stream to Europe, a journey which takes two and a half years. They swim back up the rivers. There they live for about ten years before the return journey to the Atlantic. How do they do this？ We know what happens to the eels but not how or why.
"Migration" in this passage means
A．the seasonal moving of creatures.
B．settling down in a new place.
C．the activity controlled by magnetism.
D．knowing where one is going and making no mistakes.

Step Back in Time
Do you know that we live a lot longer now than the people who were born before us？ One hundred years ago the average woman lived to be 45. But now， she can live until at least 80.
One of the main reasons for people living longer is that we know how to look after ourselves better. We know which foods are good for us and what we have to eat to make sure our bodies get all the healthy things they need.We know why we sometimes get ill and what to do to get better again. And we know how important it is to do lots of exercise to keep our hearts beating healthily.
But in order that we don"t slip back into bad habits， let"s have a look at what life was like 100 years ago.
Families had between 15 and 20 children， although many babies didn"t live long.Children suffered from lots of diseases， especially tickets （佝偻病 ） and scurvy （坏血病） ， which are both caused by bad diets. This is because many families were very poor and not able to feed their children well.
Really poor families who lived in crowded cities like London and Manchester often slept standing up，bending over a piece of string， because there was no room for them to lie down.
People didn"t have fridges until the 1920s. They kept fresh food cold by storing it on windowsills （窗台板 ） ， blocks of ice， or even burying it in the garden.
Some children had to start work at the age of seven or eight to earn money for their parents. If you had lived 100 years ago， you might well be selling matchsticks （火柴杆） （a job done by many children ） or working with your dad by now.

B.Wrong
C.Not mentioned
