Our bodies are wonderfully skillful at keeping balance．When the temperature jumps, we sweat to cool down．When our blood pressure falls, our hearts can do something．As it turns out, though, our natural state is always changing．Researchers are finding that everything from blood pressure to brain function changes regularly with the cycles of sun, moon and seasons．And their insights （洞察力） are getting new ways for keeping away such common killers as heart disease and cancer．Only one doctor in 20 has a good knowledge of the scientific use of time in medicine．But according to a new American Medical Association, three out of four are eager to change that．“The field is exploding,” says Michael Smolensky．“Doctors used to look at us like, What spaceship did you get off ? Now they're thirsty to know more．”
In medical school, most doctors learn that people with chronic conditions should take their medicine regularly．“It’s a terrible way to treat disease,” says Dr Richard Martin．For example, asthmatics （气喘患者） are most likely to suffer during the night．Yet most patients try to keep a constant level of medicine in their blood day and night, whether by breathing in on an inhaler （吸入器） four times a day or taking a pill each morning and evening．In recent studies, researchers have found that a large mid afternoon dose of a bronchodilator （支气管扩张剂） can be as safe as several small doses, and better for preventing nighttime attacks．
If the night belongs to asthma, the dawn belongs to high blood pressure and heart disease．Heart attacks are twice as common at 9 a．m．as at 11 p．m．Part of the reason is that our blood pressure falls at night, then rises as we start to work for the day．“Doctors know that,” says Dr．Henry Black of Chicago's Medical Center, “but until now, we haven't been able to do anything about it．” Most blood - pressure drugs provide 18 to 20 hours of relief （减缓）．But because they’re taken in the morning, they're least effective when most needed．“You take your pill at 7 and it's working by 9,” says Dr．William White of the University of Connecticut Health Center “But by that time you've gone through the worst four hours of the day with no protection．” Bedtime medicine would prevent high blood pressure, but it would also push blood pressure to dangerously low levels during the night．
Researchers are finding that _________ ．
A．heart disease and cancer are the most common killers of human beings
B．only blood pressure and brain function are decided by cycles of sun, moon and seasons
C．the functions of human bodies have much to do with nature
D．any change in human bodies goes with changes in the surroundings
According to the author, it is best for asthmatics to take their medicine _________ ．
A．at certain time
B．each morning and evening
C．when the disease occurs
D．at midafternoon
Which of the following statements is NOT true?
A．Doctors know more about illnesses than before．
B．Doctors in the U．S．used to be thirsty to know more about the new medical field．
C．The researchers' insights are providing new methods to prevent common killers．
D．The correct use of time in medicine attracts more attention in medical circle in the U．S．A．
The suggested title for this passage might be _________．
A．Medicine Is Everything B．Treatment Is Everything
C．Timing Is Everything D．Prevention Is Everything

Common sense would tell us that physically active children may be more likely to become active and healthy adults.
In the United States, elementary and middle schools are advised to give students two and a half hours of physical activity a week. That is what the Centers for Disease Control and Prevention and the American Heart Association recommend. They say high schools should provide about four hours of physical activity each week.
Yet many schools across the country have reduced their physical education programs. Just this week, a study reported that lifeexpectancy has fallen or is no longer increasing in some parts of the United States. The situation is worst among poor people in the southern states, and especially women. Public health researchers say it is largely the result of increases in fatness, smoking and high blood pressure. They also blame differences in health services around the country.
In 2006, a study found that only four percent of primary schools provided daily physical education all year for all grades. This was true of eight percent of middle schools and two percent of high schools. The study also found that twenty-two percent of all schools did not require students to take any P.E.
Charlene Burgeson , a health expert says one problem for P.E. teachers is that schools are under pressure to put more time into academic subjects. Also, parents may agree that children need exercise in school. Yet many parents today still have bad memories of being chosen last for teams because teachers favored the good athletes in class.
But experts say P.E. classes have changed. They say the goal has moved away from competition and toward personal performance, as a way to build a lifetime of activity. These days, teachers often lead activities like weight training and yoga.
Some parents like the idea of avoiding competitive sports in P.E. class. Yet others surely dislike that idea. In the end, schools may find themselves in a no-win situation.
【小题1】The underlined word “expectancy” in Paragraph 3 probably means “ ”
| A．quality | B．length | C．exception | D．depth |

Do you know what your child is going to do when the school bell rings at the end of the day? More than 14 million students leave school every afternoon and have nowhere to go, since they do not have access to(使用) affordable afterschool opportunities. According to the National Youth Violence Prevention Resource Center (NYVPRC), 90% of the Americans think all youths should have access to afterschool programs(课外活动项目), but twothirds of parents say they have trouble finding programs locally. The bad news is that the situation may be getting worse.
Afterschool hours are the peak time for juvenile crimes and risky behaviors, including alcohol(酒精) and drug(药物) use. NYVPRC states that children who do not spend any time in afterschool activities are 49 percent more likely to use drugs and 37 percent more likely to become a teen parent. Kids are also at the highest risk of becoming a victim of violence after school, particularly between the hours of 2 p.m. and 6 p.m. The highest amount of juvenile crime occurs between 3 p.m. and 4 p.m., when most children are dismissed from school(放学).
The NYVPRC defines afterschool programs as safe and structured activities that offer children opportunities to learn new skills. The skills students learn can range from technology and math to reading and art. Some programs also offer opportunities for internship (实习), community service, or mentoring. These programs have been shown to improve academic achievement, as well as relieve the stresses(减压) on working families. A report by the U.S. Department of Education and the U.S Department of Justice shows that students in afterschool programs have fewer behavioral problems and more selfconfidence, and can handle conflicts better than students who are not involved with these programs. In addition, according to the Harvard Family Research Project, afterschool programs help students from low income families overcome the inequities (不公平) they face in the school system.
1.Which of the following is TRUE according to the first paragraph?
A．Most parents don't believe in afterschool programs.
B．Students are not willing to attend afterschool programs.
C．It's difficult for parents to find afterschool programs for their kids.
D．Parents don't care about where their children go after school.
2.The underlined word “juvenile” in Paragraph 2 has a similar meaning to “________”.
A．student B．teenager C．adult D．campus
3.We learn from the second paragraph that________.
A．the teachers should watch over kids after school
B．children are dismissed from school too late
C．afterschool hours are a risky time for children
D．children should go home immediately school is over
4.The author of the passage probably________.
A．fully supports afterschool programs
B．doubts the effects of afterschool programs
C．believes structured activities are useless for children
D．thinks students today are too stressed
5.What is the theme of the passage?
A．Prevention of juvenile crimes.
B．Risks kids face after school.
C．A research report on the stresses of the students.
D．The benefits of afterschool programs.
