The smell of fresh air is becoming something of a distant memory, thanks to our increasing use of fragrance (香气). From air fresheners to scented (有香味的) candles, we live in a world of scent.

Recent figures show seven in ten people use air fresheners or scented candles to keep our homes smelling sweet. Yet recent records suggest that perfumed products could affect our health, causing problems including allergies (过敏), headaches and asthma (哮喘) .

One leading expert believes nearly a third of people suffer health effects from being exposed to scents. A major problem is so-called “contact” allergy—where perfumes and scented products cause eczema (湿疹) when they come into contact with the skin. About one in 20 is thought to be affected by fragrance allergy.

“Often it may not be immediately obvious that you have developed a fragrance allergy,” says Dr. Baron. “You don’t react immediately. Gradually, as you are exposed more and more, the body increases its reaction, until it becomes noticeable to you.”

People with pre-existing eczema are particularly vulnerable (易受影响). “The eczema worsens in areas in contact with perfumes,” says Dr. Baron. “But even those without allergies can be at risk of fragrance allergy.” You can become suddenly allergic to perfumes and personal care products that you have been using for years. “Even if you know which fragrance causes a problem, it can be difficult to avoid, as most personal care products –soap, shampoo, sun cream and washing powder—contain fragrances,” says Dr. Baron.

And strong scents can also cause headaches. Fragrances activate the nose’s nerve cells, stimulating the nerve system associated with head pain. To minimize risk, sufferers are advised to minimize the contact.

“Fragrance suggests cleanliness – yet people are smelling a potentially dangerous chemical mixture,” says Anne Steinemann, professor of the University of Washington. “We often use them to mask one problem – as with air fresheners – but create a greater one – adding poisonous chemicals to the air.”

1.What is the text mainly about?

A. The world trend of using fragrance.

2.Which of the following questions does the text NOT answer?

A. our bodies have an immediate reaction to fragrance.

B. seven in ten have suffered fragrance allergy.

C. fragrance can affect people who don’t have allergy.

D. people can avoid contacting with fragrance easily.

4.The following paragraph might discuss .

A. the asthma caused by strong scents.

B. people’s efforts to protect fresh air.

C. the methods of curing eczema.

D. the bad effects of air fresheners.

请阅读下面短文,并按照要求用英语写一篇150词左右的文章。

Cleanliness is important to academic success at one Chinese university where compulsory labor is part of a program designed to award class credits while teaching students with proper moral values.

During winter,the sky is still dark at 6:30 A. m.when the first year students in Trade and Management College in Zhengzhou begin sweeping the 165 acre campus and it can take up to an hour.

Mr.Sun,the university official,said labor is good for building character and promotes “the spirit of hard work.” Some students also claim that they are always proud of the clean campus.They never litter because they’ve been through the labor and understand that they should respect the fruits of labor of others.

Some students,however,are against it because they feel the demands of the cleaning program are a distraction.Some often show up late and hungry to their morning classes after rushing to sweep the campus and clean their rooms.

I am a writer. I spend a great deal of my time thinking about the power of language—the way it can evoke(唤起) an emotion, a visual image, a complex idea, or a simple truth. Language is the tool of my trade. And I use them all—all the Englishes I grew up with.

Born into a Chinese family that had recently arrived in California, I’ve been giving more thought to the kind of English my mother speaks. Like others, I have described it to people as “broken” English. But I feel embarrassed to say that. It has always bothered me that I can think of no way to describe it other than “broken”, as if it were damaged and needed to be fixed, as if it lacked a certain wholeness. I’ve heard other terms used, “limited English,” for example. But they seem just as bad, as if everything is limited, including people’s perceptions(认识)of the limited English speaker.

I know this for a fact, because when I was growing up, my mother’s “limited” English limited my perception of her. I was ashamed of her English. I believed that her English reflected the quality of what she had to say. That is, because she expressed them imperfectly her thoughts were imperfect. And I had plenty of evidence to support me: the fact that people in department stores, at banks, and at restaurants did not take her seriously, did not give her good service, pretended not to understand her, or even acted as if they did not hear her.

I started writing fiction in 1985. And for reasons I won’t get into today, I began to write stories using all the Englishes I grew up with: the English she used with me, which for lack of a better term might be described as “broken”, and what I imagine to be her translation of her Chinese, her internal(内在的) language, and for that I sought to preserve the essence, but neither an English nor a Chinese structure. I wanted to catch what language ability tests can never show: her intention, her feelings, the rhythms of her speech and the nature of her thoughts.

1.By saying “Language is the tool of my trade”, the author means that ______.

A. she uses English in foreign trade

B. she is fascinated by languages

C. she works as a translator

D. she is a writer by profession

2. Which of the following is TRUE according to Paragraph 3?

A. Americans do not understand broken English.

B. The author’s mother was not respected sometimes.

C. The author’ mother had positive influence on her.

D. Broken English always reflects imperfect thoughts.

3.The author gradually realizes her mother’s English is _____.

A. well structured B. in the old style

C. rich in meaning D. easy to translate

4.What is the passage mainly about?

A. The changes of the author’s attitude to her mother’s English.

B. The limitation of the author’s perception of her mother.

C. The author’s misunderstanding of “limited” English.

D. The author’s experiences of using broken English.

Dear Sally,

It feels such a long time since last time I see you. So far my summer in Xiamen has been great! I spent all my weekends at the beach. I am getting a nice tan(黝黑) and you can not longer say I am paler than you . I’ve been playing lots of beach volleyballs, and just this passed weekend I got the first place in a match! On weekends I work in a club which I teach kids to draw. Although the pay isn’t high, but I love the job very much, because I like drawing and I love kids a lot. I hope the summer’s been going good for you too. There is only one month left in the summer vacation and after that it’s time to school. Would you like to meet up some time before school starting? I want to share with you the photos I’ve taken. I’ll give you call when I return home. See you soon!

Love,

Mary

At the beginning of the World Series of 1947,I experienced a completely new emotion,when the National Anthem was played. This time,I thought,it is being played for me,as much as for anyone else.This is organized major league baseball,and I am standing here with all the others;and everything that takes place includes me.

About a year later,I went to Atlanta,Georgia,to play in an exhibition game.On the field,for the first time in Atlanta,there were Negroes and whites.Other Negroesbesides me.And I thought: What I have always believed has come to be.

And what is it that I have always believed? First,that imperfections are human.But that wherever human beings were given room to breathe and time to think,those imperfections would disappear,no matter how slowly.I do not believe that we have found or even approached perfection.That is not necessarily in the scheme of human events.Handicaps,stumbling blocks,prejudices — all of these are imperfect.Yet,they have to be dealt with because they are in the scheme of human events.

Whatever obstacles I found made me fight all the harder.But it would have been impossible for me to fight at all,except that I was sustained by the personal and deep-rooted belief that my fight had a chance.It had a chance because it took place in a free society.Not once was I forced to face and fight an immovable object.Not once was the situation so cast-iron rigid that I had no chance at all.Free minds and human hearts were at work all around me;and so there was the probability of improvement.I look at my children now,and know that I must still prepare them to meet obstacles and prejudices.

But I can tell them,too,that they will never face some of these prejudices because other people have gone before them.And to myself I can say that,because progress is unalterable,many of today's dogmas (教条)will have vanished by the time they grow into adults.I can say to my children: There is a chance for you.No guarantee,but a chance.And this chance has come to be,because there is nothing static with free people.There is no Middle Ages logic so strong that it can stop the human tide from flowing forward. I do not believe that every person,in every walk of life,can succeed in spite of any handicap.That would be perfection.But I do believe — and with every fiber in me — that what I was able to attain came to be because we put behind us (no matter how slowly) the dogmas of the past: to discover the truth of today;and perhaps find the greatness of tomorrow.

I believe in the human race.I believe in the warm heart.I believe in man's honesty.I believe in the goodness of a free society.And I believe that the society can remain good only as long as we are willing to fight for it — and to fight against whatever imperfections may exist.My fight was against the barriers that kept Negroes out of baseball.This was the area where I found imperfection,and where I was best able to fight.And I fought because I knew it was not doomed to be a losing fight.It couldn't be a losing fight-not when it took place in a free society.And in the largest sense,I believe that what I did was done for me — that it was my faith in God that sustained me in my fight.And that what was done for me must and will be done for others.

1.Why did the author say he had experienced a completely new emotion?

A. Because he won game.

B. Because he was an American.

D. Because the National Game was played for him.

2.From the passage,we know that the author is ___________.

A. an African

A. humans are imperfect if they all unite together to overcome the difficulties.

B. humans needn't approach perfect even if they can.
