the sun was a god (神). They thought the god drove across the sky each day on a golden horse. Now we
know the earth goes round the sun. It takes the earth a year to go all way round the sun. Today men even
know how far it is for the earth to go round the sun. They tell us that the earth travels over a thousand miles
a minute on its journey round the sun.
The sun is really a star. It is much bigger than the earth and it is very hot. Some people have been to the
moon but we know that no one can ever go to the sun. It is far too hot for people to live anywhere near it.
The sun is three hundred thousand times heavier than the earth and more than million times larger.
B. a god on a golden horse
C. a god with golden dress
D. a god and a golden horse
B. 100,000
C. 6,000,000
D. 60,000
B. the time the earth travels one thousand miles.
C. one circle the earth goes round the sun.
D. the journey of the earth.

These large orange and black insects (昆虫) brighten parks and gardens as they fly lightly among the flowers.
What makes monarchs particularly interesting is that they migrate (迁飞)-all the way to California or Mexico
and back. They are thought to be the only insect that does this.
Every year in the late summer monarchs begin their journey to the south. Those heading for Mexico go first
for the Louisiana-Mississippi area, then fly across the Gulf of Mexico into Texas. Once in Mexico, they settle
themselves in one of about fifteen places in a mountain forest filled with fir trees. Each place provides a winter
home for millions of monarchs. The butterflies are so many that they often cover entire trees. When spring
comes, they begin their long journey north.
The question is often asked whether every butterfly makes the round-trip journey every year. And the answer
is no. The average monarch lives about nine months. So one flying north might lay eggs in Louisiana and then
die. The eggs of that generation may be found in Kentucky; the eggs of the next generation may end up in
Wisconsin or Michigan. The last generation of the season, about the fourth, will make their way back to Mexico
and restart the journey.
Scientists learn about monarchs" migration by catching and making marks on the insects. By recatching a
monarch with such a mark and noticing where it came from, the next scientist can get to know things like the
butterfly"s age and its routing (路线).
B. an area in Mississippi
C. a forest in Mexico
D. a plain in Texas
B. by examining the marks made on them
C. by comparing their different ages
D. by counting the dead ones in the forests
B. Scientists" interest in monarchs.
C. Winter home of monarchs.
D. Migration of monarchs.
by day and pale by night. The crab"s changing colour follows a regular twenty-four hour plan that exactly
matches the daily rhythm of the sun.
Does the crab actually keep time, or does its skin simply answer to the sun"s rays, changing colour
according to the amount of light which strikes it? To find out, biologists kept crabs in a dark room for two
months. Even without daylight, the crab"s skin colour continued to change exactly on time.
This characteristic probably developed gradually in answer to the daily rising and setting of the sun, to help
protect the crab from sunlight and enemies. After millions of years it has become completely controlled inside
the living body of the crab.
The biologists noticed that once each day the colour of the fiddler crab is especially dark, and that each day
this happens fifty minutes later than on the day before. From this they discovered that each crab follows not
only the rhythm of the sun but also that of the tides (潮水). The crab"s period of greatest darkening is exactly
the time of low tide on the beach where it was caught!
B. protects the crab from the sunlight and enemies
C. keeps the crab warm
D. is of no real use
B. changed colour more quickly
C. changed colour more slowly
D. changed colour on the same timetable
B. over millions of years
C. by the work of biologists
D. both A and B
B. Discoveries in Biology
C. A scientific Study
D. A Living Clock
research shows that chemicals added to our local water supply to kill harmful bacteria can have unwanted
side effects. These chemicals can cause potential harm through drinking and in seemingly harmless activities
as cleaning one"s house. They are released (set free) from water by daily actions like water running out of tap,
spraying from garden pipes, or splashing in dishwashers and washing machines. As the water is moving, these
chemicals are released into the air and then breathed in. Once inside our bodies, they start to affect our health.
Does this mean we should stop bathing? No, say the scientists, but we should put all pollution into
perspective. Activities at home such as the burning of coal, cooking oil, or even candles release carbon
monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or
living near heavy traffic. New rugs, bedding, and even clothing give off that "new smell," which is a sure sign
of chemicals. In the office, newly applied paint, newly purchased telephones and other telecommunications
equipment, and computers release polluting chemicals, too. As offices and homes often have inadequate
ventilation (通风), these chemicals can build up to become health problems. Their poisonous effects are only
now being slowly recognized.
These facts suggest that, at a minimum, proper airing of newly purchased goods with an obvious chemical
smell is a wise warning. Home and office windows should be opened during good weather. Evenone"s car
needs to be ventilated as well while in the garage.
We need further research to understand better other potential health dangers, too. For example, the effects
of overcrowding of schools (carbon dioxide build-up), the factory work environment (an endless list of
potentially dangerous substances), and even home heating and cooling (the air conditioner may be our enemies,
not our friends) have only recently started to come to light. Until we understand the effects of our new
technological environment better, we can only hope that "there is no place like home."
B. The water in everyday use is unsafe.
C. Chemicals are added to the drinking water.
D. Chemicals are released in the running water.
B. homes and offices should be aired often
C. any pollution should be taken into consideration
D. we should prevent any pollution from doing harm to us
B. To show us that no place is like home.
C. To make us aware of the pollution around us.
D. To argue that neither homes nor offices are safe.
anger, or joy, typically make Americans feel uncomfortable and embarrassed. The shedder of tears (落泪者)
is likely to apologize, even when a great tragedy was the cause. The observer of tears is likely to do everything
possible to put an end to the emotional tears. But judging from recent studies of crying behavior, both those
responses to tears are often inappropriate and may even be counterproductive (适得其反).
Humans are the only animals clearly known to shed emotional tears. Since evolution has given rise to few
purposeless physiological responses, it is logical to assume that crying has one or more functions that enhance
(increase) survival.
Although some observers have suggested that crying is a way to ask for assistance from others (as a crying
baby might from its mother), the shedding of tears is hardly necessary to get help. Loud cries would have been
quite enough, more likely than tears to gain attention. So, it appears, there must be something special about tears
themselves.
Indeed, the new studies suggest that emotional tears may play a direct role in reducing stress. University of
Minnesota researchers who are studying the chemical composition of tears have recently separated two
important chemicals from emotional tears. Both chemicals are found only in tears that are shed in response to
emotion. Tears shed because of exposure to cut onion would contain no such substance.
Other researchers are mvestigating the usefulness of tears as a means of making a careful examination of
human ills and monitoring drugs. At Tulane University"s Tear Analysis Laboratory, Dr. Peter Kastl and his
colleagues report that they can use tears to detect drug abuse, to study the causes of "dry eye" syndrome (综合
症) and the effects of eye surgery, and perhaps even to measure exposure to environmental pollutants.
B. The embarrassment and unpleasant feeling of the observers.
C. The tear shedder"s apology and the observer"s effort to stop the crying.
D. Linking illness with crying and finding the chemical composition of tears.
B. we can reduce our stress by shedding tears
C. shedders of tears can"t get help by crying loudly
D. unlike animals, humans can shed tears for survival
B. Functions of shedding tears.
C. Unwelcome shedders of tears.
D. Research on the effects of tears.
