【题目】 When John was growing up, other kids felt sorry for him. His parents always had him weeding the gardencarrying out the garbage and delivering newspapers. But when John reached adulthood, he was better off than his childhood playmates. He had more job satisfaction, a better marriage and was healthier. Most of all, he was happier.Far happier.

These are the findings of a 40year study that followed the lives of 456 teenage boys from Boston. The study showed that those who had worked as boys enjoyed happier and more productive lives than those who had not. “Boys who worked in the home or community gained competence (能力) and came to feel they were worthwhile members of society”said George Vaillant, the psychologist (心理学家) who made the discovery. “And because they felt good about themselves, others felt good about them.”

Vaillant's study followed these males in great detail. Interviews were repeated at ages 25, 31 and 47. Under Vaillant, the researchers compared the men's mentalhealth scores with their boyhood activity scores. Points were awarded for parttime jobs, housework, effort in schooland ability to deal with problems.

The link between what the men had done as boys and how they turned out as adults was surprisingly sharpThose who had done the most boyhood activities were twice as likely to have warm relations with a wide variety of peoplefive times as likely to be well paid and 16 times less likely to have been unemployed. The researchers also found that IQ and family social and economic class made no real difference in how the boys turned out.

Working—at any age—is important.Childhood activities help a child develop responsibility, independence, confidence and competence—the underpinnings (基础) of emotional health. They also help him understand that people must cooperate and work toward common goals. The most competent adults are those who know how to do this.Yet work isn't everything. As Tolstoy once said“One can live magnificently in this world if one knows how to work and how to love, to work for the person one loves and to love one's work.”

1What do we know about John?

A.He enjoyed his career and marriage.

B.He had few childhood playmates.

C.He received little love from his family.

D.He was envied by others in his childhood.

2Vaillant's words in Paragraph 2 serve as ________

A.a description of personal values and social values

B.an analysis of how work was related to competence

C.an example for parents' expectations of their children

D.an explanation why some boys grew into happy men

3Vaillant's team obtained their findings by ________

A.recording the boys' effort in school

B.evaluating the men's mental health

C.comparing different sets of scores

D.measuring the men's problem solving ability

4What does the underlined word “sharp” probably mean in Paragraph 4?

A.Quick to react.B.Having a thin edge.

C.Clear and definite.D.Sudden and rapid.

【题目】Zero gravity looks cool. But what about the thing no one likes to talk about? Yes, that is right: going to the bathroom. Zero gravity makes this everyday task quite a challenge. Astronauts have to be toilet-trained all over again.

The Apollo astronauts raised themselves off the seat of their chairs and stuck a clear plastic bag to their back sides with sticky strips. A second astronaut watched closely to be sure no waste matter escaped the seal. (You would not want that stuff floating around the cabin!) When the deed was done, the astronaut cleaned up with a piece of plastic attached to the inside of the bag, removed the bag, dropped a disinfectant(消毒剂) pill in with the waste matter, and put the whole thing, sealed, into a special container.

Donald W. Rethke, an engineer for Hamilton Standard Space Systems, developed a more private way to answer nature’s call: the space toilet. It is somewhat like the kind of toilet one would find on commercial airplanes--with unique adaptations for zero gravity, of course. For instance, it has thigh bars that keep the astronaut from floating off the seat.

The astronaut (male or female) defecates (排便) in a bag and urinates (排尿) in a hose. Solid and liquid wastes are kept separated because at least 85% of the urine is recycled and, yes, after careful filtration(过滤), used for drinking and other purposes. (Water is always in demand in space.) A vacuum sucks the waste materials into the toilet, where the waste is compacted into hamburger-like patties for easy storage. Although not exactly like an earthbound visit to the toilet, it is at the very least much more private than in the early days of space travel.

1According to the first paragraph, the lack of the gravity can turn something as simple as _______ into a major challenge.

A. eating B. answering nature’s call

C. sleeping D. going to the restroom

2How did astronauts use toilet systems in the Apollo days?

A. None of the waste was separated as it is now.

B. Solid waste was compressed and stored on board.

C. The toilet units used water to remove the waste through the system.

D. The astronauts each used their own private restroom.

3To ensure the user remains seated, the toilet comes equipped with _______

A. a plastic bag B. a sticky strip

C. a wide hose D. a thigh bar

4What can be inferred from the fact that most of the astronauts’ urine is recycled?

A. The recycled water tastes better. B. Water is limited on the space shuttle.

C. It is very convenient to get their urine recycled. D. Space science includes recycling urine.

【题目】 The bad health effects of sleep loss during the week can’t be repaid by longer weekend sleep, according to a new study.

Researchers have long known that sleep deprivation (剥夺) can cause weight gain and increase other health risks. But for those who force themselves out of bed every weekday after too few hours of shut eye, they hope turning off the alarm on Saturday and Sunday will repay the weekly sleep debt and remove any ill effects.

The research, published in Current Biology, crushes those hopes. Despite complete freedom to sleep during a weekend recovery period, people in a sleep lab who were limited to five hours of sleep on weekdays gained nearly three pounds over two weeks and experienced disorders that would increase their risk for diabetes over the long term. While weekend recovery sleep had some benefits after a single week of sleep loss, those gains were wiped out when people fell right back into their same sleep deprived schedule the next Monday.

'If there are benefits of catch-up sleep, they're gone when you go back to your daily schedule. It's very short lived', said Kenneth Wright, director of the sleep and chronobiology lab at the University of Colorado at Boulder. 'These health effects are long term. It's kind of like smoking once was-people would smoke and wouldn't see an immediate effect on their health, but people will say now that smoking is not a healthy lifestyle choice. I think sleep is in the early stage of where smoking used to be.'

Wright said that the study suggests people should put sleep in the first place cutting out the 'sleep stealers' such as watching television shows or spending time on their phones. Even when people don't have a choice about losing sleep because of child-care responsibilities or job schedules, they should think about getting sleep in the same way they would get a healthy diet or exercise.

1What does the underlined word 'rushes' mean?

A.Ruins.B.Guarantees.

C.Deepens.D.Arouses.

2What will Kenneth Wright agree with?

A.Smoking is more harmful than sleep loss.

B.Weekend recovery sleep has many benefits.

C.Smoking and sleep loss have the same bad effects.

D.It takes long for people to see the effects of sleep loss.

3What does Kenneth Wright advise people to do?

A.Take regular exercise every day.

B.Reduce the screen time before sleep.

C.Watch some TV shows before bedtime.

D.Sleep as long as possible during weekdays.

4What is the main purpose of this passage?

A.To share some unhappy experiences.B.To show some unknown facts.

C.To promote a healthy lifestyle.D.To introduce a new study.
