Arriving in Sydney on his own from India, my husband ,Rashid, zxxkstayed in a hotel for a short time while looking for a short time while looking for a house for me and our children.

During the first week of his stay, he went out one day to do some shopping. He came back in the late afternoon to discover that his suitcase was gone. He was extremely worried as the suitcase had all his important papers, including his passport.

He reported the case to the police and then sat there,lost and lonely in strange city, thinking of the terrible troubles of getting all the paperwork organized again from a distant country while trying to settle down in a new one.

Late in the evening, the phone rang. It was a stranger. He was trying to pronounce my husband’s name and was asking him a lot of questions. Then he said they had found a pile of papers in their trash can(垃圾桶)that had been left out on the footpath.

My husband rushed to their home to find a kind family holding all his papers and documents. Their young daughter had gone to the trash can and found a pile of unfamiliar papers. Her parents had carefully sorted them out, although they had found mainly foreign addresses on most of the documents. At last they had seen a half-written letter in the pile in which my husband had given his new telephone number to a friend.

That family not only restored the important documents to us that day but also restored our faith and trust in people.We still remember their kindness and often send a warm wish their way.

A.Go shopping

B.Find a house

Since the first Earth Day in 1970,American have gotten a lot “greenter” toward the environment . “We didn’t know at that time there even was an environment,let alone that there was a problem with it,”says Bruce Anderson,president of Earth Day USA.

But what began as nothing important in public affairs has grown into a social movement .Business people,political leaders,university professors,and especially millions of grass-roots Americans are taking part in the movement. “The understanding has increased many ,many times,”says Gaylord Nelson,the fromer

govermor from Wisconsin,who thought up the firstAccording to US government reports , emissions (排放)from cars and trucks have dropped from 10.3 million tons a year to 5.5 tons .The number of cities producing CO beyond the standard has been reduced from 40 to 9 .Although serious problems still remain and need to be dealt with , the world is a safer and healthier place .A kind of “Green thinking ” has become part of practices .

Great improvement has been achieved .In 1988 there were only 600 recycling programs ,; today in 1995 there are about 6,600 .Advanced lights ,motors , and building designs have helped save a lot of energy and therefore prevented pollution .

Twenty –five years ago , there were hardly any education programs for environment .Today , it’s hard to find a public school , university , or law school that does not have such a kind of program .” Until we do that , nothing else will change! ” say Bruce Anderson .

5 According to Anderson , before 1970, Americans had little idea about ___

A the social movement

B recycling techniques

C environmental problems

D the importance of \Earth Day

6 Where does the support for environmental protection mainly come from?

A The grass –roots level

B The business circle

C Government officials

D University professors

7 What have \Americans achieved in environmental protection ?

A They have cut car emissions to the lowest

B They have settled their environmental problems

C They have lowered their CO levels in forty cities.

D They have reduced pollution through effective measures .

8.What is especially important for environmental protection according to the last pargraph ?

A Education

B Planning

C Green living

D CO reduction

One of the latest trend(趋势) in American Childcare is Chinese au pairs. Au Pair in Stamford, for example, has got increasing numbers of request for Chinese au pairs zxxkfrom aero to around 4,000 since 2004. And that’s true all across the country.

“I thought it would be useful for him to learn Chinese at an early age” Joseph Stocke, the managing director of s company, says of his 2-year old son. “I would at least like to give him the chance to use the language in the future,” After only six months of being cared by 25-year-old woman from China, the boy can already understand basic Chinese daily expressions, his dad says.

Li Drake, a Chinese native raising two children in Minnesota with an American husband, had another reason for looking for an au pair from China. She didn’t want her children to miss out on their roots.” Because I am Chinese, my husband and I wanted the children to keep exposed to(接触) the language and culture.” she says.

“Staying with a native speaker is better for children than simply sitting in a classroom,” says Suzanne Flynn, a professor in language education of Children.”But parents must understand that just one year with au pair is unlikely to produce wonders. Complete mastery demands continued learning until the age of 10 or

12.”

The popularity if au pairs from china has been strengthened by the increasing numbers of American parents who want their children who want their children to learn Chinese. It is expected that American demand for au

pairs will continue to rise in the next few years.

9.What does that term” au pair” in the text mean?

A. A mother raising her children on her own

B. A child learning a foreign language at home

C. A professor in language education of children

D. A young foreign woman taking care of children.

10. Li Drake has her children study Chinese because she wants them ______.

A. to live in China some day

B. to speak the language at home

C. to catch up wit other children

D. to learn about the Chinese culturezxxk

11. What can we infer from the text?

A. Learning Chinese is becoming popular In America,

B. Educated woman do better in looking after children

C. Chinese au pairs need to improve their English Skills.

D. Children can learn a foreign language well in six months.

can work well with your appetite and schedule. The more you learn and the more you try, the more ability you have to take control of your food and your schedule.

Hopefully that gives you a good start. 20_______ And don’t let a busy schedule discourage you from making some great changes in the way you eat and live!

A. Try new things.

B. Ability is easily improved.

C. Make three or four instead.

D. Understand your food better.

E. Cooking is a burden for many people.

F. Let cooking and living simply be a joy rather than a burden.

G. A little time planning ahead can save a lot of work later on.
