In Singapore，most of us love window-shopping while some others enjoy having a picnic at East Coast Park or Changi Beach on sunny days．Singaporeans are never bothered by the occasional thunderstorm．However，we know that if it rains for long continuous periods，there will be more serious effects．Just recently the main shopping street of Orchard Road was flooded and some part of Bukit Timah was impassable(不能通行的)to traffic．People reacted by writing in to the newspaper to complain about this! We forget that other countries suffer much worse effects.

Elsewhere，heavy tropical(热带的)storms often result in floods that ruin crops especially in Thailand and Malaysia．This in turn usually means that the price of rice and vegetables here in Singapore will rise because we import these products from them．If there is a typhoon or tsunami，thousands of lives are lost too．This happened in Indonesia and Phuket in Thailand in 2004 and It serves to remind us of how Mother Nature can cause great damage．

Weather patterns in general have changed dramatically in recent years．Scientists believe that global warming and the resulting melting of the polar ice-cap has caused the level of the ocean to rise．This in turn causes flooding of low-lying areas in countries where the land is rather flat and some parts of which is below water level．It is believed that human activities have caused Mother Nature to show her extreme anger，so it is now important that we really work together to cut down on harmful activities，for example，illegal logging(伐木)or irresponsible forest-burning to clear land for farming．

Water runs downhill from mountaintops to streams to rivers to oceans. But downhill isn’t the only way that water moves .A new study measures how water travels from country to country for human consumption. This flow isn’t the type we usually think about .These scientists looked at the water used to grow and make the products which get shipped from nation to nation as imports or exports. They call this a flow of“virtual water（虚拟水）”.

We typically think about water as the liquid that flows from a tap. However,92％of the water used by people goes into growing crops，according to water researcher Arjen Hoekstra. He recently studied the hidden travels of virtual water used in products made from things like crops and meats .These products are shipped around the world.

For example．consider a sugary soft drink. Hoekstra estimated that to produce one half-liter of the drink requires between 170 and 310litersofthewater—about 95％—is used to grow and process the ingredients(原料).Another 4％goes into the packaging and labeling. In Hoekstra’s calculation, when one country produces a half-liter of soda and sells it abroad，it exports as much virtual water as would fill a large refrigerator．

According to Hoekstra’s new report，dry countries like Israel and Kuwait，both in the Middle East, get the majority of their virtual water from other countries，through imported products. More surprisingly, some wetter countries，like the Netherlands and the United Kingdom, also get the majority of their virtual water from other places. That means that most of the water used to grow or produce the products and food consumed in those countries came from other countries.

In the United States most of the virtual water used comes from American sources .In China even less of the water associated with its products

A recent study suggests that teens’ relationship with parents, friends and teachers may have a lot to do with why they don’t get a good night’s sleep.

David Maume, a sociologist and sleep researcher, analyzed federal health data, which interviewed 974 teenagers when they were 12, and then again at 15. He found that family dynamics (动态) have much to do with how well kids sleep. Teens, who had warm relations with their parents and felt like they could talk to them or their parents were supportive of them, tended to sleep better. However, families that were going through a divorce or a remarriage tended to affect teens’ sleep.

And problems at school also affected teens’ sleep. Feeling safe at school and having good relations with teachers tended to promote better sleep. As did good relationships with friends. Kids who took part in sports or other positive social activities or shared similar academic goals with their friends were also more likely to get a good night’s sleep.

These add up to what makes lots of sense: a general feeling of well-being helps teens sleep. If we’re happy and contented, we’re much more likely to sleep better than if we’re sad and anxious.

Now, of course, teens can hardly resist being drawn to their computers and social networking. Maume also found that when parents were strict not only about bedtime, but also about limiting technology, kids slept better. It’s a finding that seems obvious, but parents really do matter when it comes to health habits of their teenagers.

Clearly, teenagers aren’t getting 9 to 10 hours a night, which puts them at risk for all the consequences of lack of sleep, including poor academic performance, colds and stress.

1.What is the passage mainly about?

A. Teens’ sleep is linked to their relationship with people around them.

B. Lack of adequate sleep puts teens at risk of many bad consequences.

C. Modern technology has something to do with teens’ sleep problems.

D. It is necessary for teens to join in sports and positive social activities.

2.According to Maume’s analysis, who will probably have a poor night’s sleep?

A. Teens who feel like talking with their parents.

B. Teens who have friends sharing their dreams.

C. Teens who feel contented about themselves.

D. Teens who lack a sense of security at school.

3.Para 5 functions as .

A. a comparison B. an introductionC. a conclusionD. an addition

4.Parents are supposed to when their kids are growing up.

A. continue their broken marriageB. allow children to decide when to sleep

Unemployment in Europe has recently hit record highs. Although Denmark has been protected from economic problems thanks to its low public debt, qualified (有资格的) professionals are still finding it tough to get a job. Danish marketing firm Reputation Copenhagen has come up with a way of helping academics get noticed -- putting them on display (展示) in storefront windows.

Many highly-trained professionals, ranging from former CEOs to lawyers and tax experts, are currently finding it increasingly difficult to find proper employment on the Danish job market. Some of them have been trying for years, leaving their resumes (简历) with dozens of companies, without ever hearing back from them, and are now at a point where they are willing to try anything, even putting themselves in display windows like goods, hoping to get noticed.

Alexander Peitersen, managing director of Reputation Copenhagen, came up with the idea of using his company's office as a storefront for the campaign (活动), as there are many businesses nearby that might be interested in the talents on display. So he set up a small desk, put up the “an available academic is sitting here” sign and asked the unemployed to just sit in the windows like goods. It seems like a pretty desperate measure, but at least it works. According to the agency's website, three of the jobseekers in their window display got a job in a day or two.

Peitersen says he came up with the idea after realizing human resource managers get hundreds of job applications every day, which look more or less the same, and that creative thinking is required in order to increase the chances of finding employment. Apart from companies interested in qualified job-seekers, the campaign has also attracted the attention of both local and international media.

1.Which of the following words can be used to describe Peitersen?

A. Independent. B. Creative. C. Sensitive. D. Cautious.

2.Some job-seekers are willing to put themselves in the windows to display in that ______.

A. they think it is fashionable

B. their parents ask them to

C. it’s increasingly difficult to get hired

D. they find it’s interesting

3.It can be Inferred that ______.

A. no companies show interest in the qualified job-seekers in the windows

B. both local and international media don't agree with the campaign

C. human resource managers have to reply to hundreds of applicants

D. to some degree the window displays help people find jobs

4.What is the text mainly about?

A. Job-seekers are displayed in the windows hoping to get hired.

B. The rate of unemployment in Europe has recently become hitter.

C. It is hard for qualified professionals to get a job.

D. Denmark has avoided economic problems due to its low public debt.

—He’s always associating himself with those dishonest boys!
