Our lives were supposed to be more flexible and family-friendly thanks to the technology at our fingertips. But in this age of BlackBerrys, recession (经济衰退) pressures, working at home after hours and on weekends, family time may not be working out the way we thought.
Busy parents who expected more time with the kids are finding that more work hours at home don't necessarily translate into quality time with them.
A new generation of parents needs to discover the meaning of "quality time," researchers say. “Personally, just given the life I lead, I think there is something to this idea of quality time— spending productive time with children instead of just being around,” says Peter Brandon, a professor at Carleton College. He says engaging or interacting with a child in activities such as reading or playing counts as quality time rather than "passive monitoring," such as washing the dishes while the child is watching TV.
“This time with children pays off,” Brandon says. He notes that good parent—child relationships result in children being happier and more successful, including at school.
As parents struggle to be more available to their kids, new research on work and family schedules to be presented Friday at the meeting in Dallas includes a study that shows parents' availability is on the decline because more parents are in the workforce. Although parents today may be spending more time on child care, they are less available overall.
Working parents who spend less time with their children should try to make sure the time they do spend is communicating with them instead of doing the dishes or spending more time on themselves, Brandon says “The trade-off is not necessarily taking away time from your kid,” he says "You’d better take away time from other things.”
1.The first paragraph mainly intends to tell us that .
A. technology lets parents work at home
B. parents are satisfied with their work
C. technology makes our lives much easier
D. the family time is not always satisfying
2.We can learn from the third paragraph that .
A. some families are not experiencing quality time
B. it's enough for parents to stay with their children
C. parents enjoy engaging in work-at-home activities
D. working hours at home can transform into quality time
3.According to Brandon, the quality time means_________.
A. just, being around with children
B. work time is separate from family time
C. spending instructive time with children
D. letting the children do whatever they want to do
4.The underlined sentence “This time with children pays off ”means .
A. the time with children is of little value
B. the time with children costs quite a lot
C. the time with children leads to good result
D. the time with children has a bad effect on them
5.According to the new research on work and family schedules to be presented at the meeting in Dallas, what leads to the declining of parents’ availability ?
A. Because parents don’t know the meaning of “quality time”.
B. Because parents are unwilling to care about their children.
C. Because parents are under the great recession pressures.
D. Because more parents today are busy at their work.
6.What will the author most probably talk about in next part of the passage?
A. How to spend more time at home
B. How to do the dishes in a proper way.
C. How to spend more time on working at home.
D. How to take away time in a much proper way.

Polluted airborne particles(大气悬浮颗粒) kill 7 million people a year, reports the World Health Organization.
That news may not come as a surprise to anyone who has seen images of chimneys in Beijing, Delhi or Mexico. But those factories－or even the jammed roadways of modern cities－are not the biggest killer. Each year, some 4.3 million people die earlier than they should because of polluted air inside their homes, says the WHO.
What's causing the air inside people's homes to be so poisonous that it kills around 11,000 people a day? Stoves. “Having an open fire in your kitchen is like burning 400 cigarettes an hour.” says Kirk Smith, a professor at the University of California at Berkeley, whose research suggests that household air pollution from cooking killed between 3.5 million and 4 million people in 2013.
Not all stoves cause this kind of harm. The ones Smith's talking about are those that the 3 billion people in the developing world use for heat and cooking, which burn solid fuels such as wood, coal, or crop waste instead of gas. The smoke from those fires produces harmful fine particles and carbon monoxide into homes. Poor ventilation then prevents that smoke from escaping, raising fine particle levels 100 times higher than the limits that the WHO considers acceptable.
Breathing this air day in day out eventually causes a lot of diseases: more than a third of the 4.3 million die of a stroke, while a quarter die of heart disease. And around one-third of annual lung disease deaths worldwide are due to waste from coal stoves.
Exposure tends to be extremely harmful for the people who spend the most time around the fire－usually women and young children. In fact, the WHO reports that household air pollution almost doubles the risk for childhood lung disease.
1.According to Kirk Smith's research,________.
A. factories are the biggest killer worldwide nowadays
B. burning 400 cigarettes an hour is extremely dangerous
C. household air pollution from cooking is surprisingly harmful
D. some 4.3 million people die earlier each year than they should
2.What should be the deadly killer in a household kitchen?
A. Solid fuels. B. Coal stoves.
C. Poor gas. D. Cooking smoke.
3. The underlined word “ventilation” in Paragraph 4 probably means ________.
A. airing B. cooking C. burning D. cooling
4.The author intends to tell people ________.
A. how to avoid polluted air in their homes
B. to stop cooking in the household kitchen
C. to guard against household pollution from cooking
D. how to prevent childhood lung diseases in household

“If we can set it up so you can’t unlock your phone unless you’ve got the right fingerprint(指纹),” Barack Obama asked last Tuesday, “why can’t we do the same thing for our guns?” For this reasonable-sounding question, the president was applauded throughout the media.
As it happens, though, there is a good answer to this question: there is no market for guns that work just some of the time. Guns are simple things designed to operate as easily and reliably as possible. The introduction of electronics eats away this simplicity, and to a degree that is absolutely unacceptable to the consumer. As President Obama well knows, the fingerprint software on his phone works rather erratically: Often it takes a user two or three tries to log in; occasionally, it falls asleep deeply and obeys the password. When this happens on an phone, the user is mildly inconvenienced. If this were to happen on a gun, the user would be dead. There is a reason that modern smartphones put the camera function outside of the authentication(认证) process.
How could we possibly think that guns are the same as other commercial products? It is true that, say, cars have become considerably safer over the last few decades; true, too, that “research” has contributed to this improvement. But it matters enormously that a car is not intended to hurt people, and that in a perfect world nobody would ever be injured by one. Can we say the same of guns? Of course not. Guns are killing machines, designed explicitly to do damage to living things. In fact, they have no other purpose. As such, the salient question before any free people is not “are guns dangerous?”, they are, but “who gets them, and why?”
This is not to say that nothing at all can be done to improve public safety. On an individual level, gun owners should do everything to ensure that their guns are kept away from children, and, where possible, they should train themselves in case they are ever called upon to shoot in anger. At the national level, the combination of better policing and economic growth can help to reduce crime—and, indeed, it has. In 1993, gun crime was more than twice as common as it is now, and there were many fewer guns in circulation. Ugly as it is in its own right, that we have reached the point at which two-thirds of all guns-related deaths are deliberately self-inflicted is a small victory.
How to address those deaths that remain? That is a tricky one. I do not know the answer, and nor, frankly, does anybody else. But selling fantasies to the ignorant is not going to cut it.
1.What does the writer mainly argue in this passage?
A. Gun crime has been greatly reduced.
B. The idea of smart guns is not realistic.
C. Gun control will not succeed in America.
D. Guns-related deaths deserve public attention.
2.The underlined word “erratically” in Paragraph 2 probably means ________.
A. with effectiveness
B. with passion and energy
C. in an unpredictable manner
D. in a reasonable and fair way
3.The writer supports his ideas in Paragraphs 2 and 3 mainly by ________.
A. analyzing statistics
B. presenting problems and solutions
C. quoting the authorities
D. making comparisons and contrasts
4.Which of the following might the writer NOT agree with?
A. Few know how to deal with guns-related deaths.
B. Efforts to improve public safety have partly paid off.
C. The nature of guns distinguishes them from other products.
D. Guns using fingerprint software can risk the lives of the users.

Who knows about sleep? Astronauts (宇航员). They have to. Their bodies are cut off from the outside world that reminds (提醒) us what time it is. But actually, it's even worse than that. An astronaut reported in his diary that he was likely to make mistakes on days following an unusually late bedtime.
So NASA started doing some serious research. They quickly realized that we're a slave to the outside world. Without light and darkness, we' re unable to regulate (管理) sleep times.
Because of modern technology, we're all living more like astronauts now. Light is no longer a function (功能) of the sun, but of always-on indoor lights, TV and computer screens. Temperature no longer follows a cycle of cooling at night and warming during the day. Is it any wonder that a third of Americans have sleep problems?
Maybe you think this doesn't affect you — or at least not much. You're wrong. Research done on non-astronauts has shown the same thing. After two weeks of six hours of sleep a night; you're drunk. By the end of two weeks, the six-hour sleepers behaved as badly as those who hadn't slept for 24 hours.
But what did they say when asked how they felt? "It's not affecting me." So if you are performing poorly because of sleep problems, you may have no idea. This is a real problem.
So what answers did NASA come up with?
Take an hour to calm down before bed. Yes, you're busy. But your time is not more valuable than an astronaut's.
Keep your bedroom dark, cool and free from noise. Even if you think "the light doesn't affect you" or "the noise isn't that bad", it can still affect sleep quality.
Another advice: forget the alarm clock (闹钟) in the morning; set an alarm to remind you to go to bed at night. When it goes off, finish up any work on the computer, and turn off any unnecessary lights. This prevents you from cheating yourself on sleep and allows you to wake up naturally.
1. What did NASA find about people’s sleep?
A. It takes a long time to develop regular sleep times.
B. It’s strongly influenced by the outside world.
C. It remains untouched by outside influences.
D. It’s hard to change one’s sleep habits.
2.The biggest problem of those who haven’t enough sleep lies in the fact that .
A. they can’t fall asleep without the lights on
B. they don’t know whether they sleep well
C. they refuse to regulate their sleep times
D. they get too drunk to sleep well
3. What does the underlined sentence in the text mean?
A. You should make full use of your time.
B. You can find the time to get ready to sleep.
C. You can sleep later to finish your work first.
D. You should learn from astronauts’ way of sleep.
4. What’s the advice on the alarm clock?
A. Use it to remind you to sleep.
B. Put it far away from your bed.
C. Get up immediately when it rings.
D. Pay no attention to it when it rings.
