Scientists show a number of reasons for this return to the nest.The marriage age is rising, a condition that makes home and its pleasantness particularly attractive to young people.A high divorce (离婚) rate and a low remarriage rate make some differences.For some, the expense of an away - from - home college education has become so great that many students now attend local schools.Even after graduation, young people find their wings tied by terrible housing costs.
Living at home, says Knighton, a school teacher, continues to give security (安全保卫) and moral(道义的) support.Her mother agreed.“Its strange for the kids to pay all that money for rent.It makes sense for kids to stay at home.” But sharing the family home requires changes for all.There are the hassles over bathrooms, telephones and privacy.Some families, however, manage the careful balancing act.But for others, it proves too difficult.Michelle Del Turco, 24, has been home three times and left three times.“What I considered a social drink, my dad considered an alcohol (酒精) problem,” she explains.“He never liked anyone I dated, so I either had to hide away or meet them at friends" houses.”
Just how long should adult children live with their parents before moving on? Most scientists feel lengthy homecomings are a mistake.Children, can end up with a sense of defeat and failure.And aging parents, who should be enjoying some freedom, find themselves stuck with too many things.Many agree that brief visits, however, can work well.

Some construction materials, including fiberboard, insulation foams and certain glues for man-made wood floor boards, for example, give out organic products such as formaldehyde (甲醛). Heat and humidity increase the release of formaldehyde and the gas seriously harms the eyes. Paint, lacquer, etc. can also release dangerous gas into indoor air.
Construction materials can cause serious damage, especially when they contain asbestos(石棉). Asbestos is naturally present in rock formations worldwide. It belongs to a family of mineral substances made up of solid, non-combustible(非易燃品) fiber. These properties make asbestos a highly sought-after construction material. As early as 1931, however, public health officers in the United Kingdom revealed the connection between breathing in asbestos dust and such diseases as lung cancer.
The land on which a building is sited may also contribute to pollution. Some kinds of granite or similar rocks contain traces of radium. As it breaks down, this naturally radioactive element produces some kind of radioactive gas that goes through tiny cracks in walls, floors and building materials, and makes its way into the building and the rooms. The better the homes are insulated, the more is the dangerous gas in indoor air. The main effect of this dangerous gas on health is to increase the risk of lung cancer.
小题1:What is the main idea of the passage?
A.Some building materials pollute indoor air. |
B.Some factors cause indoor air pollution. |
C.Asbestos can cause lung cancer. |
D.The land on which houses are built contributes to indoor pollution. |

D.They spend most of their time indoors. |
A.It is a kind of insulation foam. |
B.Asbestos will not give out dangerous gas. |
C.This material is not easy to catch fire. |
D.It is rarely present in rock formations. |
A.To determine whether the land is firm enough for a building to be sited on. |
B.To make sure that the land contains no radioactive material. |
C.To make certain that the land releases no formaldehyde or other gases. |
D.To check whether it contains any combustible materials. |

Right now, the American space suit weighs about 275 pounds and is big and massive. But the suit is also easy to work in for long periods of time. The Russian space suit is less complicated, but is used only a few times and then gets thrown away.
“Finding the right balance is always going to be a challenge,” said a long-time astronaut Jeff Williams. Williams has worn both types of suits. Space suits protect astronauts from both extreme heat and freezing temperatures. They carry life-packs with oxygen for the astronauts. They also shield astronauts from radiation, or particles that send out harmful rays.
Scientists are using computers to design the new suits. This allows them to change the design again and again, and to even test the design out before actually making anything. “There’s a lot more capable tools and technology to get the job done——a lot more knowledge, as well,” said Joe Kosmo. Kosmo helped design, develop, and test suits during the Mercury, Gemini, Apollo, Skylab, and shuttle periods.
These new space suits will be much lighter and use a new kind of complex material. They also will have a smaller life support backpack, thanks to tiny electronics. NASA hopes to have the first prototypes(原型) in development by 2010 and certify(证明) the suit by 2012. This will be in time for the launch of the Orion spaceship in 2014.
小题1: What characteristic does the new space suit have?
A.The new space suit will need much maintenance. |
B.The new space suit will be heavier than before. |
C.The new space suit will have less mobility than before. |
D.The new suit will use new technology to help astronauts be safe in outer space. |
A.The Russian space suit is big and massive. |
B.The Russian space suit is much complicated. |
C.The Russian space suit is merely used a few times. |
D.The Russian space suit is easy to work in for long periods of time. |
A.harm | B.protect | C.help | D.warn |
A.Because designing the new space suit is not a complex task. |
B.Because computers are being used to help scientists design the new space suits. |
C.Because it needs little knowledge to design the new space suits. |
D.Because the scientists only change the old space suits a little and make them into the new ones. |
A.Two years. | B.Three years. | C.Four years. | D.Six years. |
Unplugged is being run by Dr Roman Gerodimos,a lecturer in Communication and Journalism at Bournemouth University.During the experiment,Dr Gerodimos said there were already signs of how much the exercise affected volunteers.He said:“They’re reporting withdrawal symptoms,overeating,feeling nervous,isolated and disconnected.”
During their 24-hour test,three of the experiment’s participants were followed around by a BBC reporter plus cameraman.They were asked to write down 100 lines about their day offline,but of course,they all waited until the next day when they had access to their laptops.
Elliot Day wrote:“Today,my whole morning routine was thrown up into the air.Despite being aware of the social importance of the media,I was surprised by how empty my life felt without the radio or newspapers.”
From Caroline Scott,we read:“I didn’t expect it,but being deprived of the media for 24 hours resulted in my day-to-day activities becoming so much harder to carry out than usual…I didn’t break out in a cold sweat like our lecturer expected us all to,but It’s not something l would like to do again!”
And Charlotte Gay wrote:“I have to say the most difficult item for me to be without has been my mobile;not only is it a social device,it’s my main access point of communication.”
Earlier in the year,a UK government study found that in the UK we spend about half our waking hours using the media,often plugged into several things at once.So,with technology continuing to develop at an alarming rate,how much time will you set aside for sleep in the future?

People in different countries and different places of the world eat different kinds of things. Foods are cooked and eaten in many different kinds of ways. People in different countries eat at different times of the day. In some places people eat once or twice a day; in other countries people eat three or four times a day. Scientists say that none of the differences is really important. It doesn’t matter whether foods are eaten raw or cooked, canned or frozen. It doesn’t matter if a person eats dinner at 4 o’clock in the afternoon or at eleven o’clock at night. The important thing is what you eat every day.
There are two problems, then, in feeding the large number of people on earth. The first thin g is to find some ways to feed the world’s population so that no one is hungry. The second is to make sure that people everywhere have the right kind of food to make them grow to be strong and healthy.
小题1: According to the scientists, which of the following groups of food is the healthiest for your lunch?
