Parents vary greatly in their degree of strictness towards their children. Some may be especially strict in money matters. Others are severe (严格的) over time of coming home at night or punctuality for meals. In general, the controls represent the needs of the parents and the values of the community as much as the child"s own happiness.
As regards the development of moral standards in the growing child, consistency is very important in parental teaching. To forbid a thing one day and excuse it the next is no foundation for morality (道德). Also, parents should realize that "example is better than precept". If they are not sincere and do not practice what they preach (说教), their children may grow confused when they grow old enough to think for themselves, and realize they have been to some extent fooled.
A sudden awareness of a marked difference between their parents" principles and their morals can be a dangerous disappointment.
B. is universal among parents
C. sets up dangerous states of worry in the child
D. will make the child lose interest in learning new things
B. should expect a lot of the children
C. should achieve a balance between pushing them too hard and leaving them on their own
D. should create as many learning opportunities as possible
B. parental controls reflect only the values of the community
C. parental restrictions vary, and are not always for the benefit of the children alone
D. it"s parents" and society"s duty to control the children
B. punishment
C. behavior
D. instruction
B. be aware of the huge difference between adults and children
C. forbid their children to follow hook teachings
D. always ensure the security of their children

sun and other stars. The atmosphere again acts as our protective blanket on earth. Light gets through,
and this is essential (不可缺少的) for plants to make the food which we eat. Heat, too, makes our
environment endurable. Various kinds of rays come through the air from outer space, but enormous
quantities of radiation from the sun are screened off (用屏幕隔开). As soon as men leave the
atmosphere, they areexposed to this radiation but their spacesuit or the walls of their spacecraft, if they
are inside, do prevent a lot of radiation damage.
Radiation is the greatest known danger to explorers in space. The unit of radiation is called "rem".
Scientists have reason to think that a man can put up with far more than 0.1 rem without being damaged;
the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about
radiation damage - a person may feel perfectly well, but the cells of his or her sex organs may be
damaged, and this will not be discovered until the birth of deformed (畸形的) children or even
grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and, during the
outward and return journeys, the Apollo crew accumulated (积累) a large amount of rems. So far, no
dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We
simply don"t know yet how men are going to get on when they spent weeks and months outside the
protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage
done by radiation, but no really effective ones have been found so far.
B. it provides sufficient (充分的) light for plant growth
C. it supplies the heat necessary for human survival
D. it screens off the falling meteors
B. seems overestimated
C. is enormous
D. remains unknown
B. protection from space radiation is no easy job
C. astronauts will have deformed children or grandchildren
D. radiation is not a threat to well-protected space explorers
B. Research on Radiation
C. Effects of Space Radiation
D. Importance of Protection Against Radiation
men in which deaths from heart disease were more than 50 percent lower among those who consumed at
least an ounce of salt water fish per day compared to those who never ate fish.
The Dutch research is one of three human studies that give strong scientific support to the long held
belief that eating fish can provide health benefits, particularly to the heart.
Heart disease is the number-one killer in the United States, with more than 550,000 deaths occurring
from heart attacks each year. But researchers previously have noticed that the incidence (发生率) of
heart disease is lower in cultures that consume more fish than Americans do. There are fewer heart
disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a
day, and among the Japanese, whose daily fish consumption averages more than 3 ounces.
For 20 years, the Dutch study followed 852 middle-aged men, 20 percent of whom ate no fish.
At the start of the study, average fish consumption was about two-thirds of an ounce each day, with more men eating lean fish than fatty fish.
During the next two decades, 78 of the men died from heart disease. The fewest deaths were among
the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos. This
relationship was true regardless of other factors such as age, high blood pressure, or blood cholesterol
(胆固醇) levels.
B. the changes in people"s diet
C. the effect of fish eating on people"s health
D. the daily fish consumption of people in different cultures
B. in highly-developed countries
C. in countries of the yellow-skin race
D. in the countries with good production of fish
the incidence of heart disease.
B. regular fish-eating
C. the kind of fish eaten
D. people of different areas
old. Yet doctors in the United States say babies begin learning on their first day of life.
Scientists note that babies are strongly influenced by their environment. They say a baby will smile
if her mother does something the baby likes. A baby learns to get the best care possible by smiling to
please her mother or other caregiver. This is how babies learn to connect and communicate with other
human beings.
One study shows that babies can learn before they are born. The researchers placed a tape recorder
on the stomach of a pregnant woman. Then, they played a recording of a short story. On the day the
baby was born, the researchers attempted to find if he knew the sounds of the story repeated while in
his mother. They did this by placing a device in the mouth of the newborn baby.
The baby would hear the story if he moved his mouth one way. If the baby moved his mouth the
other way, he would hear a different story. The researchers say the baby clearly liked the story he heard
before he was born. They say the baby would move his mouth so he could hear the story again and again.
Another study shows how mothers can strongly influence social development and language skills in their
children.
Researchers studied the children from the age of one month to three years. The researchers attempted
to measure the sensitivity of the mothers. The women were considered sensitive if they supported their
children"s activities and did not interfere unnecessarily. They tested the children for thinking and language
development when they were three years old. Also, the researchers observed the women for signs of
depression.
The children of depressed women did not do as well in tests as the children of women who did not suffer
from depression. The children of depressed women did poorly in tests of language skills and understanding what they hear.
These children also were less cooperative and had more problems dealing with other people. The
researchers noted that the sensitivity of the mothers was important to the intelligence development of their
children. Children did better when their mothers were caring, even when they suffered from depression.

C. The children of depressed but caring mothers.
D. Children with high communication abilities.
B. Scientific findings about how the environment has an effect on babies" intelligence.

The breakthrough, which scientists say is the first new way to generate electricity in 160 years, could
lead to batteries that use water instead of poisonous substances.
The scientists made the discovery when they were investigating what happens when tap water is
forced through extremely narrow glass tubes. Water squeezed down the tubes, each of which was
narrower than a tenth the thickness of a human hair, generating a small electric current that ran the length
of the tube. To produce a larger electric current, the team tried forcing water through a glass water filte
r(滤水器) that contained thousands of narrow channels lined up side by side. "When we took a syringe (注射器) of water and squeezed it through the filter, we got enough power to light a light bulb," said
Larry Kostiuk of the University of Alberta in Canada. "The harder you push the syringe, the more electric
current you get."
The current is produced because of an effect in the glass tubes. When they are filled with water,
positively charged ions (阳离子) fixed in the tubes are washed away, leaving a slight negative charge on
the glass surface. When water is then forced along the tube, the surface repels negatively charged ions in
the water while positively charged ions are attracted down the tube. The result is a net flow of positively
charged ions that sets up an electric current.
According to Dr Kostiuk, no one has ever thought to use water to produce electricity in this way.
"The last time someone came up with a way of generating electricity was Michael Faraday in 1839," he
said. "So this is the first new way of generating electricity in 160 years, which is why we are so excited
about it."
Dr Kostiuk says water batteries might one day be used to power mobile phones and calculators, but
admitted that the engineering challenges might make other applications more realistic. "You"d need to be
sure it wouldn"t leak, and you"d need to make sure it wouldn"t freeze," he said.
More likely would be to install the electricity-generating devices where water is already being pumped, such as at city water filtration sites, he said. "It could compete with wind and solar power," he added.
B. A kind of new energy source found in tap water.
C. The breakthrough to generate electricity 160 yeas ago.
D. A kind of new battery invented without poisonous substances.
B. identifies
C. attracts
D. rebels
B. They could make an electric current to light a light bulb.
C. Their discovery could be used to invent water batteries.
D. Their discovery was made 160 years earlier than Faraday"s.
B. They have some possible disadvantages like water leaking.
C. They would be needed greatly at city water filtration sites.
D. They would be better than wind and solar power.
S.D., so commuting (经常往返) to class isn"t the problem. But he doesn"t like lectures much, isn"t a
morning person, and wants time during the day to restore motorcycles.
So Steele, a full-time senior business major, has been taking as many classes as he can from the
South Dakota State system"s online offerings. He gets better grades and learns more, he says, and
insists he isn"t missing out on the college experience.
"I still know a lot of people from my first two years living on campus, and I still meet a lot of people,"
he says. But now, he sets his own schedule.
At least 2.3 million people took some kind of online courses, according to a recent survey by The
Sloan Consortium, an online education group, and two-thirds of colleges offering "face-to-face" courses
also offer online ones. But what were once two different types of classes are looking more and more
alike and often falling into the same pool of students.
At some schools, online courses originally intended for non-traditional students living far from campus
have proved surprisingly popular with on-campus students. A recent study found 42 percent of the
students enrolled (登记) in its distance education courses were located on campus at the university that
was hosting the online courses.
Numbers vary depending on the policies of particular colleges, but other schools also have students
mixing and matching online and "face-to-face" credits. Motives range from lifestyle to adapting a job
schedule to getting into high-demand courses.
Washington State had about 325 on-campus undergraduates taking one or more distance courses last
year. As many as 9,000 students took both distance and in-person classes at Arizona State last year.
"Business is really about providing choices to their customers, and that"s really what we want to do,"
said Sheila Aaker, extended services coordinator (协调人) at Black Hills State.
Many schools, such as Washington State and Arizona State, let departments and academic units
decide who can take an online course. They say students with legitimate academic needs-a conflict with
another class, a course they need to graduate that is full-often get permission, though they still must take
some key classes in person.
B. To tell us about the development of campus courses.
C. To show the differences between campus courses and online courses.
D. To show more on-campus students are taking online courses.
B. knows none of his classmates
C. wants to have his own lifestyle
D. doesn"t get good marks
B. It is expected that distance education is popular with on-campus students.
C. About 325 on-campus undergraduates took online courses in Washington last year.
D. Different colleges have different policies about online courses.
B. colleges should provide more majors for students
C. where the similarity between business and colleges lies
D. why colleges offer online courses to on-campus students
