It seems parents have long been right. Going to bed early is key to getting enough sleep and helping adolescents feel on top of the world, a new study reported.
A   1  of sleep among youngsters may    2  depression and suicidal (自杀的)thoughts, according to the study by the Columbia University Medical Center.
"Our results are   3  with the theory that inadequate sleep is a risk factor for depression, working with other   4  and protective factors through multiple possible causal pathways to the development of this   5  disorder," said lead author James Gangwisch.
"  6  quality sleep could therefore be a preventative measure against   7  and a treatment for depression," he added in the study   8  in the Friday issue of Sleep magazine.
The study followed the nightly habits of some 15,659 college and high-school students, and   9  those who consistently went to bed   10  midnight had a 24 percent higher risk of depression than those who turned in before 10:00 pm.
Night owls(夜猫子)also ran a 20 percent   11  risk of battling suicidal thoughts, the study added.
The American Academy of Sleep Medicine   12  that adolescents should sleep at least nine hours or more a night. Those who were tucked in before 10:00 pm reported they slept    13  about eight hours and 10 minutes.
But that amount of sleep  14  significantly for those in bed after midnight.
And adolescents who slept five hours or less a night were 71 percent more   15  to suffer depression and 48 percent more     16  becoming suicidal, the study said.
"It is a common perception and societal   17  that adolescents do not need as much sleep as pre-adolescents, yet studies suggest that adolescents may  18  require more sleep," said Gangwisch.
"Studies have found that adolescents do not go to bed   19  enough to make up for earlier school start times, and transitions to earlier school start times have been shown to be   20  with significant sleep deprivation(剥夺). "

本文说明的是一项最新研究报告称,早睡不仅是得到充足睡眠的关键,而且有助于改善青少年的情绪。完成本完形填空时,我们应把生活中的实际和作者的思路逻辑联系起来。
1. D 检测名词的含义辨析及在语意上的合理搭配。语意是:这项由哥伦比亚大学医学中心开展的研究表明,青少年缺乏睡眠可能会引发抑郁以及自杀的念头。经过分析我们不难看出此处应该填上表示缺乏之意的名词,也即是D项:lack,而其余的ABC三项依次分别所表达的意思:晚上,中度,限制,这些意思在这儿都不符合此处的上下文之间语言逻辑。故D项为准确答案。
2. A考查动词短语的含义准确记忆和理解辨析。由上一题的分析我们能够判断出此处应该填上表示引发之意的动词词组,而A项就表示这样的意思,BD项依次分别所表示:在于,出现,带来,这些意思都和这儿的语言逻辑和作者的要表达的意义不契合。故我们选择A项为最佳答案
3. D考查形容词的含义辨析及在语言逻辑方面的准确应用。由分析,得出语境是:研究报告的主要撰写人詹姆斯?冈维西说:“有理论认为睡眠不足是导致抑郁的风险因素之一,它与其他风险和保护因素相互作用,通过多种可能的因果途径,造成这种情绪失调。我们的研究结果与这一理论是一致的。我们不难看出此处应该填上表示一致的含义的形容词,就是D项:consistent。AB两项项依次分别所表达的意思:相反的,混合的,明显不是这样的意思,而C项的意思最容易让人上当,因为它的意思是相关,不过也与上面的分析不太吻合。故我们选择D项为最佳答案。
4. A 检测名词的含义辨析及在语言逻辑方面的准确应用。由上一题的分析我们不难看出此处应该填上表示风险之意的名词,也即是A项:而BCD项依次分别所表达的意思:机会,潜能,原因等等都不切合此处的上下文之间语言逻辑。故A项为准确答案。
5. A 考查名词的含义记忆与理解辨析。由第三题的分析我们能够确定此处应该表示情绪意思的名词,也就是A项。BCD项依次分别所表达的意思是:身体,情感,意志,这些意思在这儿都不符合此处的上下文之间语言逻辑。故我们选择A项为最佳答案
6. C 检测形容词的含义的准确记忆与理解。联系上下文的语境我们容易推理出这一句的语境是:“所以,充足、高质量的睡眠可以成为防治抑郁症的一项措施。”研究报告在上周五的《睡眠》杂志上发表。结合语境我们发现此处需要填上表示充足意义的形容词,这四个词中只有C项有这样的之意,而BCD项依次分别所表达的意思是:少的或小的,缺少,过量,这些意思在这儿都不符合此处的上下文之间要求的语言逻辑。故我们选择C项为最佳答案。
7. B 检测名词的含义辨析及联系上下文语言逻辑能力。由上一题的分析我们不难看出此处应该填上表示抑郁症之意的名词,也即是B项:depression。而不是ACD三项依次分别所表达的意思:遭遇,紊乱,悲伤。故B项为准确答案。
8. B 考查动词过去分词的含义辨析及生活常识。我们都有这样的常识,研究结果一般刊登在报刊杂志或者网络。此处应该填上表示刊登之意的动词的过去分词,这是因为其逻辑主语是study,它们之间是被动关系,故B项为准确答案。而ACD项依次分别所表达的意思:报道,反映,指出等等,在语言逻辑方面的都不准确。
9. A 考查动词的含义辨析及在语言逻辑方面的准确应用。经过联系上文分析,语意是:该研究对15659名大学生和中学生的夜间作息习惯进行了追踪调查,发现那些经常在午夜后就寝的学生患抑郁症的风险比那些在晚上10点前就上床睡觉的学生高24%。我们不难看出此处应该填上表示发现之意的动词,这四个词中只有A项有这样发现之意,也就是find的过去式。而BCD项依次分别所表达的意思:调查,评价,支持等等都在语言逻辑方面不能与之准确吻合。故我们选择A项作为最佳答案。
10. D 考查介词词的含义辨析及在语言逻辑方面的准确理解和应用。由上一题的分析我们不难断定此处应该填上表示在…..之后意思的介词,也即是D项,ABC项依次分别所表达的在……之前,从……,经由……,等等意思,都不符合此处上下文之间的语言逻辑,故D项为准确答案。
11. B 考查形容词的比较级的含义辨析及在上下文之间的语言逻辑方面的准确应用。经过联系上文分析,语意是:研究称,晚睡者产生自杀念头的风险也要高20%,这四个词中只有B项有较高之意。而ACD项依次分别所表达的意思是:较低的,较多的,较少的,这些意思在这儿都不符合此处的上下文之间语言逻辑,故B项为准确答案。
12. B 考查动词的含义辨析及在语言逻辑方面的准确应用。由语境:美国睡眠药物学会建议,青少年每晚睡眠时间至少要达到9个小时,我们分析中不难看出此处应该填上表示建议之意的动词,也即是B项。而ABD项依次分别所表达的意思是:呼吁,叫或打电话,计划,这些词语所表示的意思都和这儿的语言逻辑不契合,故B项为准确答案。
13. A 经过分析,语意是:晚上10点前就寝的人称他们平均每天的睡眠时间约为8小时10分钟。这四个词中只有A项有平均之意。而BCD项依次分别所表达的意思是:有秩序,提前,在数量上,联系上下文的语境我们容易这不恰当,故我们选择A项为最佳答案。
14. D考查动词的含义辨析及在语言逻辑方面的准确应用。语意是:但那些在午夜后睡觉的人的睡眠时间明显少很多。这里的少就是降低的意思,也就是D项。而ABC这三项依次分别所表达的意思是:增加,消失,加强,这些词语所表示的意思都和这儿的语言逻辑不契合,故我们选择D项为最佳答案。
15. A检测副词的含义的准确记忆与理解。研究报告说,每晚睡眠时间为五小时或更少的青少年患抑郁症的几率高71%,出现自杀倾向的几率高48%。这里的几率就是我们所说的可能性,而这四个都表示可能的这样的意思。但是它们的用法是不同的,只有likely的主语可以是人或者事,其余BCD三项的主语往往都是形式主语it,故我们选择A项为最佳答案。
16. B 检测介词短语的含义的准确记忆和理解辨析及在语言逻辑方面的准确应用。由上一题的分析我们不难看出此处应该填上表示有……风险的意思,这四个词中只有B项有这样的意思。ACD项依次分别所表达的意思是:看见……,在……前面,因为……,这些意思在这儿都不符合此处的上下文之间语言逻辑,故B项为准确答案。
17. B 检测名词的含义辨析及在语言逻辑方面的准确应用。经过分析,语意是:冈维西说:“目前存在这样一种普遍看法和社会预期,认为青少年不像儿童那样需要那么多睡眠,然而研究表明,事实上青少年可能需要更多睡眠。”联系上下文的语境我们容易推理出此处应该填上表示预期之意的名词,这四个词中只有  B项有这样的意思。而其余ACD三项项依次分别所表达的意思是:愿望,建议,尝试,这些意思在这儿都不符合此处的上下文之间语言逻辑,故B项为准确答案。
18. D 检测副词的含义的准确记忆与理解。由上一题的分析我们不难看出此处应该填上表示事实上之意的副词,也即是D项,而ABC项依次分别所表达的意思是:准确地,立即地,直接地,这些词语所表示的意思都和这儿的语言逻辑不契合,故我们选择D项为最佳答案。
19. A检测副词的含义的准确记忆与理解。经过分析,语意是:“研究发现,青少年上学的时间提早了,但却没有提早就寝来对此加以补偿,而且上学时间提早与严重的睡眠剥夺有关。”联系上下文的语境我们容易推理出此处应该填上表示早早地之意的副词,也即是A项,而其余BCD项依次分别所表达的意思是:最近,时间上快,动作快,这些意思在这儿都不符合此处的上下文之间语言逻辑,故A项为准确答案。
20. B 考查动词过去分词的含义辨析及在语言逻辑方面的准确应用。由上一题的分析我们不难看出此处应该填上表示联系之意的动词过去分词,也即是B项,而ABD项依次分别所表达的意思是:分离,均分,依赖,这些词语所表示的意思都和这儿的语言逻辑不吻合,故我们选择A项为最佳答案。

“I Love You”Virus
On May 21,1999,some American scientists were working at the computers to look for information they needed.Suddenly they saw a lot of very bright red spots crossing the computers’screens.At the same time the computers were working much slower.To find out what was happening they stopped their work to check some parts of the computers.To their horror,they found out that most of their stored information was got rid of by computer virus! Obviously all these computers had been infected by computer virus.
It is said that the computer virus was made by two or three Philippine young men fond of playing tricks.They all had excellent education.They created the virus just to show their intelligence.The kind of computer virus is named“I Love You”Virus.This virus can hide in computers for long.When the time comes it will attack the computers by lowering the important functions,damaging their normal programs or even getting rid of a great deal of information which operators of the computers often use or store;even worse,it still can reproduce itself in great quantities within a short time.
We come to know that “I Love You”Virus often attacks computers on Mondays and that it is spreading to many computers in the world.Among the countries that suffered computer viruses last year are Britain,Australia,Switzerland and the US.Those who made the computer viruses have been found out slowly and carefully.But till now,how to get rid of the terrible viruses remains a problem.

On June 5, 1981 the Centers for Disease Control in Atlanta, U.S. announced the presence of a rare, infectious disease in five American homosexuals(同性恋). Soon doctors were finding similar cases all over the country and the world. The AIDS epidemic(流行病)had officially begun. By 1983 it was clear that AIDS had spread around the world. More than twenty years later, AIDS has left twenty-six million dead and another forty million infected.  AIDS has become the worst medical disaster ever experienced by mankind.
Hundreds of young people between the ages of 20 and 45 died each week during the early years of the U.S. AIDS. More than 600,000 cases of AIDS have been reported since 1981 in the United States, and it is estimated that there may be as many as 900,000 Americans infected with HIV.
Though the rate of HIV infections continues to increase in the United States, the number of AIDS cases has fallen sharply since 1996, when antiretroviral drugs came onto the market. Unfortunately, the AIDS epidemic continues today in Africa and much of Asia, where antiretroviral treatment is not available and health care is far from enough. AIDS is the fourth leading cause of death worldwide, and the No. 1 cause of death due to infectious disease.
HIV, the virus that causes AIDS, was first separated in 1983 by a team at the Pasteur Institute in Paris. That discovery made it possible to develop a test for AIDS and trace back to victims who may have died before doctors were aware of the disease.
However, scientists still don't know exactly how and where AIDS started. Finding the source of AIDS could be important in developing a vaccine(疫苗) and be important in mapping the future course of the epidemic.
小题1:It can be inferred from the passage that       
A.antiretroviral drugs will be obtained easily all over the world
B.the best way to stop AIDS is to develop a vaccine
B.scientists will soon find a way to cure AIDS
D.there will be fewer AIDS cases in the world in the future
小题2:Which areas are the most worrying places where AIDS spreads quickly? 
A.Africa.B.Asia.C.The United States.D.France.
小题3:The number of AIDS cases has greatly decreased in the United States due to the fact
A.a team at the Pasteur Institute in Paris succeeded in separating HIV
B.some effective medicine has been invented
B.scientists understand AIDS better and better.
D.The rate of HIV infections continue to rise in the United States
小题4:What's the importance of the discovery of the source of AIDS?
A.It can be used to develop a test for AIDS.
B.It can stop HIV forming AIDS.
B.It can reduce the rate of death caused by AIDS.
D.It can help develop a drug to prevent AIDS.
Like poorly managed stress, anger that isn’t handled in a healthy way can be not only uncomfortable, but even damaging to one’s health and personal life. Consider the following research on anger:
One study from the University of Washington School of Nursing studied   1  problems in husbands and wives. Researchers cited(引用) previous evidence that anger problems and depressive symptoms have been linked to all major   2  of death, but found that wives specifically found a greater association between anger and  3  of depression,   4  men tended to instead experience an   5  between anger and health problems.
According to a study from Ohio State University, those who had less control over their anger   6  to heal more slowly from wounds. Researchers gave blisters(起疱膏) to 98 participants and found that, after 8 days, those who had less control over their anger also tended to be   7  healers.    8  , those participants also tended to have more cortisol (a stress hormone) in their system during the blistering procedure,   9  that they may be more stressed by difficult situations as well.
  10  study from Harvard School of Public Health studied hostility(敌对行为) in men and found that those with  11  rates of hostility not only had poorer pulmonary functioning (breathing problems), but experienced higher rates of decline as they aged.
Research with children and   12  shows that anger   13  is important for the younger set as well. Findings showed that youth who cope inappropriately with their anger are at greater   14  for problem-ridden(受…支配的) interpersonal relationships. Their   15  is also at risk; those who cope poorly with anger tend to have more negative   16  when it comes to both mental and general health. This highlights the fact that anger management is an important skill to   17  early.
These are just a few of the many studies linking anger to   18  and emotional health problems, from the obvious to the   19  . Because poorly managed anger presents such a significant problem in so many areas of life, it’s important to take steps toward learning and using healthy anger management techniques in daily life,    20  stress management techniques.

There is an old saying in English: "Laughter is the best medicine". Until recently, few people took the saying very seriously. Now, however, doctors have begun to investigate laughter and the effects it has on the human body. They have found evidence that laughter really can improve people's health.
Tests were carried out to study the effects of laughter on the body. People watched funny films, while doctors checked their heart rate, blood pressure, breathing and muscles. It was found that laughter has similar effects to physical exercise. It increases blood pressure, the heart rate and the rate of breathing; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter exercises the body, it must be beneficial.
Other tests have shown that laughter appears to be capable of reducing the effect of pain on the body. In one experiment doctors produced pain in groups of students who listened to different radio programs. The group which tolerated the pain for the longest time was 'the group which listened to a funny program. The reason why laughter can reduce pain seems to be that it helps to produce endorphins (内啡肽) in the brain. These are natural chemicals which diminish both stress and pain.
There is also some evidence to suggest that laughter helps the body's immune(免疫的)system, that is, the system which fights infection. In an experiment, one group of students watched a funny video while another group served as the control group - in other words, a group with which to compare the first group. Doctors checked the blood of the students in both groups and found that the people in the group that watched the video had an increase in the activity of their white blood cells, that is, the cells which fight infection.
As a result of these discoveries, some doctors and psychiatrists (精神病学家) in the United States now hold laughter clinics, in which they try to improve their patients' condition by encouraging them to laugh. They have found that even if their patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to those caused by laughter.

The high noise of modern life may affect speech and language development in the very young, according to a study that found the auditory (听觉的) parts of the brains of young mice are slower to organize properly in the presence of continuous sounds.
Researchers at the University of California, San Francisco, reared a group of rats in an environment of continuous background noise and found that their brain circuits that receive and interpret (解释) sound did not develop at the same rate as animals that were raised in a quieter environment.?
Edward F. Chang and Michael Merzenich, co-authors of the study appearing in the journal Science, said that the continuous noise delayed the organization of auditory neurons (神经细胞) during a critical two-to-three-week period after the rat pups were born.?
For rats not exposed to the noise, the auditory cortex(皮层) neurons during this period gathered into a smaller area and began developing a selective response to sounds.?
But for the noise?exposed rats, this organization was slowed, causing a delay in the development of the ability to discriminate(辨别) specific sound tones. The researchers said it took three or four times longer for the rats raised in a noisy environment to reach the basic bench marks (基准) of auditory development seen in the rat pups not exposed to noises.?
Although the rat is not a perfect model for what happens in humans, the authors note, the study does suggest that high levels of noise might possibly affect some language learning in babies.?
“These findings suggest that environmental noise, which is commonly present in contemporary child-rearing environments, can potentially contribute to auditory and language-related development delays,”the authors wrote in Science.?
The authors noted that although the brain development was delayed in rats exposed to the noise, their brains did eventually mature (成熟的) normally.?
小题1:The scientists at California University studied rats_______.?
A.of different age groupsB.with different habits?
C.in different environmentsD.from different areas?
小题2:The rats exposed to noise, compared to those not exposed, _______.?
A.were more sensitiveB.were duller?

Seeing a volcano erupt (喷发) is a wonderful experience, and you can really feel the beat by climbing to the summit(山顶) of Pacaya for a close-up view. There are guided tours every day up this highly active volcano from Antigua. Giving travelers a chance to see Mother Nature at her most powerful.
Pacaya is an easy drive from Antigua, a beautiful city with many colorful houses along its old streets that are turned into art-works during its Holy Week festival. No matter when you come to Antigua, you won’t miss the Pacaya-tour companies.
But climbing Pacaya is no easy job: it is 2560 metres high, and reaching the summit takes two to three hours of seemingly one-step-forward and two-step-back movements. As you climb, you hear the dull sounds of eruptions high above. Steaming. Hot remains from recent eruptions begin to line the path as you near the active summit; the McKenney Cone(火山锥). Just as though you were going to walk over to the edge of the cone, the road turns to the left and up to the relative safety of the old, inactive summit.
Many tours are timed so that you arrive at the cone of the volcano is plenty of time for sunset and the full contrast between the erupting red lava(熔岩) and the darkening sky. On a good day the view from the summit is extremely exciting. The active mouth boils, sending red lava over its sides, and once in a while shoots hot streams up to 100 metres into the air. There is a strong bad smell in the air even if you take care to be upwind of the cone. As evening turns deeper into the night. the burning lava quietly falls down tae side of the volcano. For you, too, it is time to get down .
小题1: What is the main purpose of this passage?
A.To attract tourists to Pacaya. B.To describe the beauty of Pacaya.
C.To introduce guided tours to Pacaya.D.To explain the power of nature at Pacaya.
小题2:Antigua is a city      .

Scientists say they have discovered a promising treatment for sleeping sickness, a killer disease that infects(感染) about 60,000 people in Africa a year.
British and Canadian experts say drugs could attack the parasite(寄生虫) causing the illness needs to survive. They say the drug could be ready for human medical test in about 18 months.
The disease, spread by the bite of a fly, is caused by a parasite attacking the central nervous system. It has similar symptoms(症状) to malaria(疟疾), making it difficult to diagnose. Left untreated, it moves to the brain, resulting in mental confusion and final death
The "breakthrough" came at the University of Dundee in Scotland, where scientists were offered money to research diseases ignored by major drugs companies.
Professor Paul Wyatt, director of the programme, said: "This is one of the most significant findings made in recent years in terms of drug discovery and development for ignored diseases."
He said the research, published in the journal Nature, represented "significant progress" in the development of a full blown drug against the disease.
The World Health Organization said there are between 50,000 and 70,000 cases of the disease a year, with a further 60 million people at risk of infection.
The research in Dundee was backed by partners at the University of York in England and the Structural Genomics Consortium in Toronto, Canada. The two drugs currently available to treat sleeping sickness both have problems. One is with side effects that kill one in 20 patients and the other is costly, only partially effective and requires long-time hospital treatment, the scientists said.
