The flying fox is not a fox at all. It is an extra large bat that has got a fox’s head, and that feeds on fruit. Like all bats, flying foxes hang themselves by their toes (趾) when at rest, and travel in great crowds when out flying. A group will live in one place for years. Sometimes several hundreds of them occupy a single tree. As they return to the tree towards sunrise, they quarrel among themselves and fight for the best places until long after daylight.

Flying foxes have babies once a year, giving birth to only one at a time. At first the mother has to carry the baby on her chest wherever she goes. Later she leaves it hanging up, and brings back food for it to eat. Sometimes a baby bat falls to the ground. Then the older ones fly down and try to pick it up. If they fail to do so, it will die. Often hundreds of baby bats can be found lying on the ground at the foot of the tree.

   [1] Medical research is leading American education officials to consider having high school classes start later in the morning. The research says that teenagers are more awake later at night than adults are. When staying up late at night, the teenagers have problems learning early in the morning.

[2]Researchers in the state of Rhode Island measured the amount of the hormone(荷尔蒙) melatonin(降黑素) in people's mouths at different times of the day. Melatonin causes people to feel sleepy.

   [3]They found that melatonin levels rise later at night in teenagers than they do in children and adults. It remains at higher levels in teenagers later in the morning. They said this shows that teenagers have difficulty learning early in the morning. Yet most school systems in the United States begin high school classes at about seven o'clock.

   [4]A few school districts have made some changes. In 1996, school officials in Edina, Minnesota, changed the start of classes from seven thirty to eight thirty. Two years later, the nearby city of Minneapolis did the same. Teachers there reported that students were no longer sleepy in class and were happier. Staying in school later in the day did not seem to be a problem for students who had jobs after school either.

   [5]Health experts say that teenagers need between eight and nine hours of sleep a night. Students _________ are likely to be late for school, fail to do their homework, fall asleep in class and have trouble taking part in class discussions.

     [6]Some people, however, don't support a later start time because they say that it would limit the time for practicing sports after school. However, the Minnesota schools found that this did not hurt school sports competitions.

     [7]More American school districts are discussing the possibility of changing high school start times. Researchers and teenagers say that they cannot make the change quickly enough.

Contrary to many people believe, highly intelligent children are not necessarily certain to achieve academic success. In fact, so-called gifted students may fail to do well because they are unusually smart. Ensuring that a gifted child reaches his or her potential requires an understanding of what can go wrong and how to satisfy the unusual learning requirements of extremely bright young people.
One common problem gifted kids face is that they, and those around them, place too much importance on being smart. Such an emphasis can encourage a belief that bright people do not have to work hard to do well. Although smart kids may not need to work hard in the lower grades, when the work is easy, they may struggle and perform poorly when the work gets harder because they do not make the effort to learn. If the academic achievement of highly intelligent children remains below average for an extended period, many teachers will fail to recognize their potential. As a result, such students may not get the encouragement they need, further depressing their desire to learn. They may fall far behind in their schoolwork and even develop behavior problems.
IQ is just one element among many in the recipe for success—Children develop well or struggle in school for a host of reasons apart from IQ. These include motivation and persistence, social competence, and the support of family, educators and friends.
Because highly gifted children solve the most varied thought problems faster and more thoroughly than those with more average talents do, they need additional intellectual stimulation while they wait for the rest of the kids to learn the basics. Two central approaches are used to satisfy the educational needs of such children: acceleration and enrichment. Acceleration means studying material that is part of the standard subjects for older students. Enrichment involves learning information that falls outside the usual subjects.
A child might skip one or more grades as a way of accelerating in school. But being with older children for the entire school day—and perhaps for grade-based extracurricular activities such as sports—can make a child feel inferior in every filed outside of academics. One very bright fourth-grader who had skipped two grades remained far ahead of his classmates intellectually, but as his classmates reached adolescence, his social and other shortcomings became painfully apparent. While acceleration is not an option, or not a good one, enrichment can be. After all, school is not a race but an adventure in learning. As such, the goal is not finishing first but absorbing as much knowledge as possible in the time assigned. Thus, providing opportunities for a child to study topics outside the regular subjects can be at least as valuable as pushing him or her through the required material faster.
【小题1】What is the basic reason for the low academic achievement of highly intelligent children?

A．Skipping one of more grades and studying together with older children.

B．Learning the same material in the standard subjects for older students.

C．Learning information that is not included in the regular subjects.

D．Learning how to read with fluency even in their pre-school days.

A．He is in favor of enrichment rather than acceleration.

B．He is in favor of acceleration rather than enrichment.

C．He speaks highly of both enrichment and acceleration.

D．He thinks neither enrichment nor acceleration is a good choice.

Many Chinese have been greatly shocked by the traffic accident caused by the drunk driver Sun Weiming, who has killed five and injured some others in Chengdu, Sichuan. However, such a case is not rare.
Today, the traffic accidents may have been regarded as a social problem. The car has killed and disabled more people in its brief history than any bomb or weapon ever invented. Much of the blood on the street flows actually from rude behavior of drivers who refuse to respect the legal and moral(道德的) rights of others. In fact, the enemies of society on wheels are rather harmless but just ordinary people acting carelessly, you might say. But it is a principle both of law and common morality that carelessness is no excuse when one's actions could bring death or damage to others. A minority of the killers go even far beyond carelessness that can be imagined.
Researchers have estimated that as many as 80 percent of all automobile accidents can be attributed to(归属于) the psychological condition of the driver. Emotional upsets can change drivers' reactions incorrectly, slow their judgment, and make them blind to the dangers that might otherwise be obvious. The experts warn that it is important for every driver to make a conscious effort to keep his/her emotions under control.
Yet the irresponsibility that accounts for much of the problem isn't only put upon drivers. Street walkers regularly ignore or break traffic regulations. They are blamed in most vehicle walker accidents, and many cyclists even believe that they are not subject（受…支配） to the basic rules of the road.
Significant legal advances have been made towards safer driving in the past few years. Safety standards for vehicles have been raised both at the point of manufacture and through regular road inspections. In addition, speed limits have been lowered. Due to these measures, the accident rate has decreased. But the accident experts still worry because there has been little or no improvement in the way drivers behave. The only real and lasting solution, say the experts, is to make people believe that driving is a skilled task requiring constant care and concentration. Those who fail to do all these things present a threat to those with whom they share the road.

I don't think there is anything wrong with your blood. The key to your problem is that long nap（打盹,小睡）after dinner. If you didn't sleep for hours during the early part of the evening, you would be more ready to sleep at bedtime. If you didn't nap after dinner, you would not want to stay up so late, and you would not feel the need to take a sleeping pill. The pill is still working in your system when you get up in the morning. This helps account for the fact that you feel tired all day. You should get out of the habit of sleeping during the evening. Right after your evening meal, engage in some sort of physical activity - a sport such as bowling, perhaps. Or get together with friends for an evening of cards and conversation. Then go to bed at your usual time or a little earlier, and you should be able to get a good nights rest without taking a pill.
　　If you can get into the habit of spending your evenings this way, I am sure you will feel less tired during the day. At first it may be hard for you to go to sleep without taking a pill. If so, get up and watch television or do some jobs around your house until you feel sleepy. If you fall asleep and then wake up a few hours later, get up but do not take a sleeping pill. Read a while or listen to the radio, and make yourself a few hours'sleep that night, you will feel better in the morning than you usually feel after taking a pill. The next night you will be ready to sleep at an earlier hour.
　　The most important thing is to avoid taking that nap right after dinner and avoid taking pills.
