Most of us use alarm clocks to wake up at the right time for school or work. We look at our watches to know the right time for the bus or train. However, there is also a right time to eat, sleep, exercise, and take medicine, too. We can’t look at a clock for the right time for these activities. We must listen to the clock inside our bodies: the biological clock.

Barbara Wells exercised every morning. She woke up at 6:00 am. She ran about two miles before she went to work. But Barbara’s legs and back started to hurt. She did some exercises before she ran. But her legs and back still hurt. She ran slower, but the pain didn’t stop. Barbara talked to her doctor. The doctor said, “Don’t run in the morning. Try to exercise later in the day. That is the time when your body is at the right temperature for exercises after work.” Her legs and back don’t hurt anymore.

Today, doctors are learning more about chronobiology (时间生物学), the study of biology clocks. They are learning about the importance of time for our bodies. For example, it is best for people to go to sleep at the same time every night and to eat only when they’re hungry. Also, doctors discovered that some illness, such as heart attacks(心脏病), occur(发生)most often in the morning. This information tells them that the best time to take heart medication may be at night. When patients take heart medicine at night, they may prevent a heart attack in the morning.

Many doctors believe chronobiology can help us live healthier lives. It may be the right time to listen to these doctors!

35. Do we all have a biological clock inside our bodies?

36 How far did Barbara Wells run every morning?

37. How did Barbara’ legs and back get well?

38. What is the right time for a heart attack person to take heart medicine?

39. What can we learn from the passage?

How should one invest a sum of money in these clays of inflation (通货膨胀)? Left in a bank it will hardly keep its value, however high the interest rate. Only a brave man, or a very rich one, dares to buy and sell on the Stock Market. Today it seems that one of the best ways to protect your savings, and even increase your wealth is to buy beautiful objects from the past. Here I am going to offer some advice on collecting antique clocks, which I personally consider are among the most interesting of antiques.
I sometimes wonder what a being from another planet might report back about our way of life. "The planet Earth is ruled by a mysterious creature that sits or stands in a room and makes a strange ticking sound. It has a face with twelve black marks and two hands. Men can do nothing without its permission, and it fastens its young round people's wrists so that everywhere men go they are still under its control. This creature is the real master of Earth and men are its slaves（奴隶）."
Whether or not we are slaves of time today depends on our culture and personality, but it is believed that many years ago kings kept special slaves to tell the time. Certain men were very clever at measuring（量） the time of clay according to the beating of their own hearts. They were made to stand in a fixed place and every hour or so would shout tire time. So it seems that the first clocks were human beings.
However, men quickly found more convenient and reliable（可靠的） ways of telling the time. They learned to use the shadows cast by the sun. They marked the hours on candles, used sand in hour- glasses, and invented water-clocks. Indeed, any serious student of antique should spend as much time as possible visiting palaces, stately homes and museums to see some of the finest examples of clocks from the past.
Antique clocks could be very expensive, but one of the joys of collecting clocks is that it is still possible to find quite cheap ones for your own home. After all, if you are going to be ruled by time, why not invest in air antique clock and perhaps make a future profit（收益）?
【小题1】According to the passage, collecting antique clocks____.

When people visit Switzerland for the first time，they look with great interest，not only at the mountains but also at a type of clock—a Cuckoo-clock，on sale there．Cuckoo-clocks are very popular with tourists looking for a souvenir．A Cuckoo-clock has a small painted cuckoo that comes out near the top of the clock every half an hour and says，“Cuckoo”．Every hour it comes out and says “Cuckoo” the right number of times．It does not get a sore throat at midnight or mid-day! Children find these clocks wonderful．Adults gradually get annoyed because the cuckoo never misses an hour or a half hour，and this makes a short sleep in an armchair rather difficult．

In Europe，the cuckoo's call is a welcome sign that summer is on the way．This is the time when the mother cuckoo flies round，looking for a nest（巢）to lay one of her eggs．She chooses a nest belonging to another bird which already has eggs．When the nest is left unnoticed for a minute or two，the cuckoo rushes down，lays an egg and hurries off．In this way，she may lay her eggs in as many as four different nests．not one of which has been built by herself．

When a cuckoo egg hatches（孵化），the baby bird is bigger and stronger than the other nestlings．Step by step，it pushes other baby birds and any unhatched eggs out of the nest．In this way，it receives all the food from its foster-parents（养父母）and has a better chance of surviving．
