B
Particles from car exhausts generate more persistent clouds but less rain, new research suggests. Furthermore, putting more of these particles into the atmosphere reduces the low-level winds, which could reduce the amount of wind power available in very polluted regions. The dry but populated regions may therefore suffer a triple blow as a result of vehicle pollution:less water, less hydropower and less wind energy.
Scientists studied the effects of aerosol(浮质)pollution from cars and industry. They correlated satellite data on wind speeds and the amount of aerosol particles in the atmosphere above the South Coast Basin in California and above China. Results showed that higher concentrations of aerosols were closely associated with slower ground winds. Scientists then used computer models to support the idea that there was a cause and effect relationship behind this correlation.
Particles floating in the atmosphere block energy from the Sun, preventing it from warming the surface of the Earth. Cooler surface temperatures during the day means the low—level and slow moving air does not rise up and mix with the faster winds at higher altitudes. Slower winds also induce less evaporation from oceans, rivers and lakes. And finally, once clouds have formed, they store less moisture in the form of rain. This is because raindrops form around small particles— dust, for instance, or pollution. With more particles in the atmosphere, it takes longer for enough water to condense(凝结)onto a particle to form a raindrop. And if the cloud of fine droplets(小滴)moves to a drier area before its would-be rain can rail, the moisture evaporates once more and the cloud disappears.
Scientists note their new work does not contradict previous findings that suggest global warming might lead to more tropical storms, because there is far less particulate(微粒的)pollution over the oceans.

Given that many people's moods (情绪)are regulated By the chemical action of chocolate, it was proBaBly only a matter of time Before someBody made the chocolate shop similar to a drugstore of Chinese medicine. Looking like a setting from the film Charlie&the Chocolate Factory, Singapore's Chocolate Research Facility (CRF) has over 100 varieties of chocolates.its founder is Chris Lee who grew up at his parents' comer store with one handalmost always in the jar of sweets.
If the CRF seems to Be a smart idea, that's Because Lee is not merely a seasoned salesperson But also head of a marketing department that has Business relations with Big names such as Levi's and Sony. That idea surely results in the imagination at work when it comes to making different flavored(味道)chocolates.
The CRF's produce is "green". made within the country and divided into 10 lines, with the Alcohol Series Being the most popular. The Exotic Series一with Sichuan pepper, red Bean (豆).cheese and other flavors一also does well and is fun to taste. And for chocolate snoBs,who think that they have a Better knowledge of chocolate than others, the Connoisseur Series uses cocoa Beans from Togo, CuBa, Venezuela , and Ghana, among others.

1.

What is good aBout chocolate?(

A. It serves as a suitaBle gift. B. It works as an effective medicine.
C. It helps improve the state of mind. D. It strengthens Business relations.

In 1947 a group of famous people from the art world headed By an Austrian conductor decided to hold an intemational festival of music,dance and theatre in EdinBurgh. The idea was to reunite Europe after the Second World War.
At the same time, the “Fringe” appeared as a challenge to the official festival.Eight theatre groups turned up uninvited in 1947,in the Belief that everyone should have the right to perform,and they did so in a puBlic house disused for years.
Soon,groups of studentsfirstly from EdinBurgh University, and later from the universities of Oxford and CamBridge,Durham and Birmingham were making the journey to the Scottish capital each summer to perform theatre By little-known writers of plays in small church halls to the people of EdinBurgh.
Today the “Fringe”,once less recognized, has far outgrown the festival with around 1,500 performances of theatre,music and dance on every one of the 21 days it lasts. And yetas early as 1959,with only 19 theatre groups performing,some said it was getting too Big.
A paid administrator was first employed only in 1971, and today there are eight administrators working all year round and the numBer rises to 150 during August itself. In 2004 there were 200 places housing 1,695 shows By over 600 different groups from 50 different countries. More than 1,25 million tickets were sold.

Doctor are known to Be terriBle pilots. They don't listen Because they already know it all. I was lucky: Became a pilot in 1970, almost ten years Before I graduated from medical school. I didn't realize then, But Becoming a pilot makes me a Better surgeon. I loved flying. As I flew Bigger, faster planes, and in worse weather. I learned aBout crew resource management (机组资源管理), or CRM, a new idea to make flying safer. It means that crew memBers should listen and speak up for a good result, regardless of positions.

I first read aBout CRM in 1980. Not long after that, an attending doctor and I were flying in Bad weather. The controller had us turn too late to get our landing ready. The attending doctor was flying; I was safety pilot He was so Busy Because of the Bad turn, he had forgotten to put the landing gear (起落架) down. He was a Better pilot - and my Boss - so it felt unusual to speak up. But I had to: Our lives were in danger. I put aside my uneasiness and said, "We need to put the landing gear down now!" That was my first real lesson in the power of CRM, and I've used it in the operating room ever since.

CRM requires that the pilot/surgeon encourage others to speak up. It further requires that when opinions are from the opposite, the doctor doesn't overreact, which might prevent fellow doctors from voicing opinions again. So when I'm in the operating room, I ask for ideas and help from others. Sometimes they're not willing to speak up. But I hope that if I continue to encourage them , someday someone will keep me from "landing gear up".

1.

What dose the author say aBout doctors in general?

A. They like flying By themselves.
B. They are unwilling to take advice.

A. he saved the plane By speaking up
B. he was in charge of a flying task
C. his Boss landed the plane too late
D. his Boss operated on a patient
3.

In the last paragraph"landing gear up" proBaBly means.

A. following flying requirements.
B. overreacting to different opinions.
C. listening to what fellow doctors say
D. making a mistake that may cost lives
4.

Which of the following can Be the Best title for the text?

A. CRM:A New Way to Make Flying Safe

D. A Pilot-Tumed Doctor

Glaucoma(青光眼)is a major cause of blindness around the world, especially in developing countries. The World Health Organization says glaucoma is a greater public health challenge than cataracts(白内障), because the blindness caused by the latter can be cured after operations.
Glaucoma is a disease that makes people around the world lose their sight, and they usually don’t even know they have the disease until it has permanently destroyed at least 40 percent of their sight. The process is usually so painless and subtle(不明显的), so people don't notice it. Actually, the simplest medical test can discover it.
“It is the leading cause of blindness in the United States. In Hispanics and in African-Americans, it’s the second leading cause of blindness and so is the case in the Chinese and Indians.” said Dr. Alan Robin, a specialist in treating glaucoma. “The glaucoma we see in sub-Saharan Africa is a much more aggressive blinding disease than the glaucoma we see in Americans or even African- Americans in-the United States.” he said..
Dr. Eric Fleischer also sees these differences at Medstar Washington Hospital Center. “Pretty much anybody who has ancestors in Africa has an increased chance of developing glaucoma.” Age is another thing that may lead to glaucoma, although people of all ages can get it.
Glaucoma is a group of diseases that commonly produce pressure in the eye. An eye is sort of like a watch. And behind the face of the watch, liquid is made. It goes through your pupil(瞳孔)and into the front of the watch between the face and the crystal.There's an area around the edge of the watch that drains(使排出)the liquid. When that drain is blocked, the liquid can't leave the eye as fast as it is produced. The rising pressure within the eye damages and eventually kills the optic(视觉的) nerve. The result is blindness.
Fortunately, if caught early, glaucoma can be controlled. Glaucoma is not curable. But as researchers worldwide lean more about it, they grow more hopeful that glaucoma can one day be cured or even prevented.
In which country is glaucoma the biggest danger to people’s sight?

A.In China B.In India C.In the USA D.In Japan

B.People in developed countries hardly develop glaucoma
C.Glaucoma only causes blindness among old people

“Dining out”, or “eating out”, is a phrase people use in Britain when they eat in a restaurant or a pub. Eating out is more popular in Britain today than ever before.
However, eating out can be expensive. Restaurants are normally more expensive than pubs, though many pubs serve very good, simple food. As British people don’t dine out every night of the week, eating in a restaurant is often seen as a special occasion. When going for the first date, or if celebrating an anniversary or a birthday, many people like to go to a restaurant. People often eat in a restaurant before going to the cinema or the theatre.
As in all cultures, there are many rules of etiquette (礼节)surrounding food and eating, and nowhere is this more pronounced than when eating in a smart restaurant. People are almost always expected to eat with a knife and fork and these should be held in the correct hand and used in the correct way. It is also impolite to have your elbows on the dining table when you are eating.
There’re many such “unspoken” rules — they are normally only important when eating in a very elegant and expensive restaurant, and vary slightly from restaurant to restaurant and place to place. A recent nationwide survey showed that there was a divide in manners between the north and south of Britain — the “worst” manners were in Scotland and the northeast, and the “best” in Wales and the southeast! However, this survey was almost certainly conducted by someone in the southeast, so it may not be entirely fair.
Naturally, restaurants vary greatly in quality and price. However, almost all British cities have a vast range of food and cooking styles to choose from as well as traditional British food,. from the very cheap to the very expensive — French, Italian, Indian, Greek, Thai, Japanese and many more. In fact, when asked what their favorite food is, many British people say an Indian curry (咖喱菜)rather than any other dish!
As well as dining in a restaurant, when people are too tired to cook after work they often get a “takeaway”. This means they order from a takeaway or takeout restaurant by phone, then go to collect it and take it home to eat. Many takeout restaurants also deliver to your house. While you can normally find a takeout restaurant for almost any cuisine, the most popular are Italian, Indian and Chinese — and all you have to do is to open the door, pay and eat!
What can be concluded from the first two paragraphs?

A.The British spend more eating out than cooking at home.
B.The British pay great attention to eating in a restaurant.
C.The British often dine out when celebrating festivals.
D.People tend to eat in a restaurant after watching a movie.

The underlined word pronounced” in Paragraph 3 probably means “_____”.

A.polite B.expensive C.strange D.obvious

According to the passage, which of the following statements is true?

A.There exist great differences of rules in different restaurants.
B.People from Wales and southeast Britain are the most polite.
C.Your order in a takeout restaurant can be sent to your home.
D.Traditional British food is seldom served in British restaurants.

What does the passage mainly talk about?

A.Restaurant culture in Britain. B.Table manners in Britain.
C.Different restaurants in Britain. D.Traditional and foreign foods in Britain.
