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）. "

The term “multitasking” originally referred to a computer’s ability to carry out several tasks at one time. For many people, multitasking has become a way of life and even a key to success. In fact, some excellent mental aerobic exercises (大脑训练) involve engaging the brain in two or more challenging activities at a time. Although checking e-mail while talking on a phone and reading the newspaper may be second nature for some people, many times multitasking can make us less productive, rather than more. And studies show that too much multitasking can lead to increased stress, anxiety and memory loss.

In order to multitask, the brain uses an area known as the prefrontal cortex (前额叶脑皮层). Brian scans of volunteers performing multiple tasks together show that as they shift from task to task, this front part of the brain actually takes a moment of rest between tasks. You may have experienced a prefrontal cortex “moment of rest” yourself if you’ve ever dialed (拨电话) a phone number and suddenly forgotten who you dialed when the line is answered. What probably occurred is that between the dialing and the answering, your mind shifted to anther thought or task, and then took that “moment” to come back. Research has also shown that for many volunteers, job efficiency (效率) declines while multitasking, as compared to when they perform only one task at a time.

Multitasking is easiest when at least one of the tasks is habitual, or requires little thought. Most people don’t find it difficult to eat and read the newspaper at the same time. However, when two or more attention-requiring tasks are attempted at one time, people sometimes make mistakes.

We often don’t remember things as well when we’re trying to manage several details at the same time. Without mental focus, we may not pay enough attention to new information coming in, so it never makes it into our memory stores. That is one of the main reasons we forget people’s names---even sometimes right after they have introduced themselves. Multitasking can also affect our relationships. If someone checks their e-mail while on the phone with a friend, they may come off as absent-minded or disinterested. It can also cause that person to miss or overlook key information being passed on to them.

In 1999, twelve percent of public elementary schools in the United States required students to wear uniforms. Just three years later, the amount was almost double that.

A study of six big-city Ohio public schools showed students who were required to wear uniforms had improved graduation, behavior and attendance rates. Academic performance was unchanged.

Some high schools in Texas have also joined in the movement. Yet studies find mixed results from requiring uniforms. And some schools have turned away from such policies.

Supporters believe dressing the same creates a better learning environment and safer schools. The school district in Long Beach, California, was the first in the country to require uniforms in all elementary and middle schools. The example helped build national interest in uniforms as a way to deal with school violence and improve learning.

Findings in Long Beach suggested that the policy resulted in fewer behavior problems and better attendance. But researcher Viktoria, who has looked at those findings, says they were based only on opinions about the effects of uniforms.

She says other steps taken at the same time to improve schools in Long Beach and statewide could have influenced the findings. The district (the area marked by government) increased punishments for misbehavior. And California passed a law to reduce class sizes.

In Florida, for example, researcher Sharon found that uniforms seemed to improve behavior and reduce violence. In Texas, Eloise found fewer discipline problems among students required to wear uniforms, but no effect on attendance.

Sociologist David has studied school uniform policies since1998．He collected the reports in the book. In his own study, he found that reading and mathematics performance dropped after a school in Pennsylvania(宾夕法尼亚州) required uniforms.

Political and community pressures may persuade schools to go to uniforms to improve learning. But David and others believe there is not enough evidence of a direct relationship. In fact, he says requiring uniforms may even increase discipline problems.

67．Which of the following researchers are NOT supporters of school uniform policies?

A．Viktoria and Sharon. B．Sharon and David.

C．Eloise and Sharon. D．Viktoria and David.

68．The underlined word“misbehavior”in the sixth paragraph probably means ________.

A．serious crime B．bad performance

C．absence for class D．action against wearing uniforms

69．What can we infer from the passage?

A．More work is needed to get better information about uniform’s effect.

B．The number of schools requiring uniforms in the U.S. will become less sharply.

C．Wearing uniforms has little to do with behavior and learning.

D．Politicians and communities won’t vote for uniform policies.

70．What’s the main idea of this passage?

A．More and more students are required to wear uniforms in the U.S.

B．Wearing uniforms contributes to good academic performance.

C．Researchers in the U.S. argue for school uniform policies.

D．Evidence for school uniform polices in the U.S. is seen as weak.

He requires that they ________ all night.
