Did you ever wonder how some of your favorite foods, products or toys came about? Believe it or not, they may have been an accident, or a failure of some other intention. Below, we found three mistakes we’re thankful for turned out to be what they are.
1. Most historians hold that the Chinese invented fireworks in the 9th century when they
discovered how to make gunpowder. Story has it that a Chinese cook accidentally mixed together what were then considered common kitchen items and noticed they burnt. When put tightly in a bamboo tube and lit, it blew up.
2. In May of 1886, a law led John Pemberton, a pharmacist（藥劑師）, to rewrite the formula(配方) for "Pemberton’s French Wine Coca,” his popular headache treatment. Containing sugar instead of wine as a sweetener, the outcome became something for Coke, which was later mixed with carbonated water. His bookkeeper suggested the name Coca-Cola because he thought the two C’s would look good together, which is how what we call Coca-Cola, a world –wide drink came into being.
3. During World War II, scientists at the University of Birmingham invented the magnetron—an important heat-producing part of the microwave oven(微波爐). While working for Raytheon Corporation after the war, the American engineer Percy Spencer was testing the magnetron when a chocolate bar in his pocket melted. He went on to test other foods including popcorn kernels, and found it to be a much more efficient way to cook. In 1947 Raytheon came out with the first restaurant microwave oven, which was six feet tall and weighed 750 lbs.   
小題1:The right time order of the three inventions, according to the passage, should be_________.
A．fireworks, the microwave and Coca-Cola
B．fireworks ,Coca-Cola and the microwave
C．Coca-Cola , fireworks and the microwave
D．the microwave, Coca-Cola and fireworks

小題3:What can we learn from the above invention stories? 
A．Experiments make great inventors of our time.
B．Nothing is impossible if one tries each day.
C．Inventors come out of hard work at any time.
D．A small incident may lead to a great invention.

Malnutrition (營(yíng)養(yǎng)失調(diào))remains a serious problem for India. But a new study shows that India’s leading causes of death now also include diseases related to obesity （肥胖）such as heart disease.
India’s National Family Health Survey shows that more than twenty percent of Indians living in cities are overweight or obese. And in the northwestern state of Punjab, that is true for almost forty percent of women.
Aradhna Tripathi is a business professional in New Delhi. She said, “ Eating is the most important thing in any Indian household and how you show your love and gratitude(感激) for a person is through the kind of food you serve him. And the kind of lifestyle we are leading is one of the reasons why we have the number of obese people increasing every day.
But Aradhna Tripathi says she has decided to lose weight. Her mother and grandmother are also diabetic(患糖尿病的). In fact, the International Diabetes Federation says India is now the diabetes capital of the world. Researchers say Indians store more body fat per kilogram than Europeans. That means obese Indians are even more at the risk of diabetes than other people.
Doctor Anoop Misra at Fortis Hospital in New Delhi says the risk of diabetes is crossing social and economic lines. Five years ago, he says, obesity and diabetes were limited to India’s richest people, but now things have changed.
But Doctor Misra is hopeful that the spread (蔓延，傳播)of obesity can be slowed. And he says it must start in schools by giving all Indian children the same instruction on physical activity and diet.
The World Health Organization says China is also moving up in obesity rates. The estimate (估計(jì)) has reached about five percent countryside and as high as twenty percent in some cities.
小題1:What is this passage mainly about?
A．Obesity has become a big killer in India.
B．Heart disease is troubling people in India.
C．People in India live a very unhealthy life.
D．Malnutrition remains a serious problem in India.
小題2:According to Aradhna Tripathi , one of the causes of the obesity problems is_________.
A．.the development of economy
B．the change of Indians’ lifestyle
C．Indians’ attitude （態(tài)度）towards eating
D．Indians’ attitude towards obesity.
小題3: What can we infer from the underlined sentence in Paragraph 5?
A．Most wealthy people in India are overweight.
B．Five years ago, few people in India were overweight
C．Few poor people are diabetic for economic reasons.
D．Now even the poor in India suffer from obesity.

This has turned out a whole generation of grown-ups  40  seldom cook a meal for themselves. If there  41  fewer of these restaurants, then probably children would buy less take-away food.
There is another argument that  42  parents for allowing their children to become overweight. I _43  this, because good eating habits begin early in life, long before children start to visit fast food shops. If children are given fried chicken and chocolate  44  healthy food, or are always allowed to choose  45  they eat, they will go for sweet and salty foods every time, and this  46  throughout their lives.
There is a third reason for this situation. Children these days  47  very little exercise. They do not walk to school.

TEENAGERS lead an exciting life in high school, making friends and dreaming about the future. However, as all young people know, teenagers have plenty of worries too.
Do you know what British teenagers worry about most? A survey by the UK's Department of Health shows that the top worries are losing weight (減肥) and fitting in (適應(yīng)). Over 100,000 teenagers took part in the research.
Losing weight is a big concern among teenagers. This may be an effect of famous people with perfect bodies around them.
Adolescence is a physically and emotionally difficult time. Teenagers want to feel good about their bodies.
It's also important for them to be accepted. Many teenagers were picked on (作弄) in high school. “Who should I eat lunch with?” “Who should I hang out with?” “Will I be accepted?” These questions are troubling many UK teenagers, according to the survey.
It's interesting to see that family background has an effect on teenagers' worries. Teenagers from low-income families worried more about losing weight and bullying (欺凌弱小). Teenagers from higher income families were more likely to worry about fitting in and peer pressure (同輩壓力).
49  According to the survey, British teenagers are most worried about ______.
A. fitting in and making money                      B. finding jobs and making friends
C. losing weight and being accepted                   D. making money and losing weight.
50.   Many teenagers are concerned about losing weight because ______.
A. they see thin famous people                              B. they care a lot about health
C. they don't have much money                                       D. they face problems in life
51.   The word “adolescence” in the fourth paragraph means ______.
A.幼兒期                          B.青春期                           C.青年期             D.老年期

A small piece of fish each day may keep the heart doctor away．That's the finding of a scientific study of Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed at least an ounce（盎司）of salt water fish per day than those who never ate fish.
The Dutch research is one of three human studies that hold the belief that eating fish can provide health benefits, particularly to the heart. Heart disease is the number-one killer in the United States, with more than 550,000 deaths occurring from heart attacks each year．But researchers previously have noticed that the incidence （發(fā)生率） of heart disease is lower in cultures that consume more fish than Americans do．There are fewer heart disease deaths, for example, among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese, whose daily fish consumption averages more than 3 ounces.

20090519

 
       For 20 years, the Dutch study followed 852 middle-aged men, 20 percent of whom ate no fish.

       At the start of the study, the average fish consumption was about two-thirds of an ounce each day with more men eating thin fish than fatty fish.
During the next two decades, 78 of the men died from heart disease．The fewest deaths were among the group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos．This relationship was true regardless of other factors such as age, high blood pressure, or blood cholesterol （膽固醇） levels.
64．Which of the following is NOT true according to the passage?
A．The Dutch research has proved that eating fish can help to prevent heart disease.
B．Heart doctors won't call at your house so long as you keep eating fish each day.
C．Among all the diseases heart disease is the most dangerous in America.
D．There is a low incidence of heart disease in Japan and Greenland.
65．The underlined phrase "this relationship" refers to the connection between ______and the incidence of heart disease.
A．regular fish-eating              B．the amount of fish eaten
C．the kind of fish eaten             D．people of different regions
66．The passage is mainly about ______.
A．the high incidence of heart disease
B．the great changes in people's diet
C．the fish consumption in some countries
D．the effect of fish eating on people 's health
67．How many lives could probably be saved each year in the United States by eating fish according to the Dutch study?
A．152,000．    B．110,000．          C．275,000．          D．550,000.

B
Over 2,000 years, the examination of the pulse has been a mysterious skill in Traditional Chinese Medicine. Although many westerners may have known something about methods like inspecting, listening and enquiring, pulse reading as a tool to determine physical condition is not common knowledge. It is therefore worth our effort to take a closer look at it.
There are three positions on each wrist which are used for analysis: the front, middle and back part, and analyzed at three different levels: superficial, middle and deep.
On the left wrist, the front position focuses on the condition of the heart and small intestine (小腸), the middle position concentrates on the functions of the liver and gall bladder, and the back position is connected with the kidney. The lungs and large intestine are the centre of attention in the front position on the right wrist, with the middle position focusing on the spleen and stomach and the back taking note of the “Gate of Vitality Fire’. This is the heat provider for all bodily functions.
In regards to the various levels, the superficial level reflects the state of energy, the middle level shows the state of blood flow, and the deep level is an indication of the state of the Yin organs. Suppose that the pulse in the left middle position was soft and smooth, neither superficial nor deep, it would suggest that the liver and gall bladder are in a good state of health.
Checking the pulse is actually far more complex. Doctors need to be able to recognize 26 different pulse categories. For example, a scattered pulse which is irregular and hardly noticeable, is a sign that a patient is critically ill and nearing death. Other categories include the rapid pulse, probably a sign of a fever; or the tense pulse, which may suggest that the patient is suffering from pain. Many pulses only have subtle differences; thus, pulse examination is often seen as being more than just a skill but an actual art form.
This kind of medical diagnosis can be affected by many factors, so before any examination, it is important that patients are in a relaxed physical and mental state so they can get the most accurate reading. The morning is often the best time to take such a reading, as a busy day in the office or vigorous exercise before seeing the doctor can influence the quality of the pulse. The right amount of pressure must be applied by the doctor for the right duration of time. Patients’ characteristics are also of importance. Children, for instance, have quick pulses and athletes have slower than usual ones. Even seasonal influences need to be taken into account.
59. Which of the following is the most suitable title for this passage?
A. Chinese Pulse Checking      B. Difficulties in Pulse Checking
C. What Makes a Good Doctor   D. Brief Introduction to Traditional Chinese Medicine
60. Which factor is NOT mentioned as possibly influencing the accuracy of a pulse reading?
A. Amount of force used.                         B. Time of day.     
C. Climate.                                          D. Body height.
61. From the passage we can infer that the writer believes __________.
A. Chinese medicine is too difficult to learn
B. pulse reading requires a long-time study and practice
C. doctors need to be familiar with Chinese history
D. pulse examination is unimportant and no longer necessary

First it was jogging. Then aerobics（有氧運(yùn)動(dòng)）. Not too long ago, Americans discovered race walking.
Now Americans are into a new fitness craze. They’re taking up bicycling. Over hills and down mountainsides and across quiet country roads, Americans are busily rolling along.
The number of adults who ride for fitness is around 17 million, an increase of 70 percent over four years ago. Twice as many women as men are coming to the sport. Americans are falling in love with biking because it has speed, the benefits of jogging and beautiful scenery.
Bicycling is a very appropriate sport, which is important to people who injured their knees while jogging or whose joints are aching from aerobics. And biking is a real awakening for people who have been into race walking in the past. Race walking is as dull as watching paint dry.
The most popular kind of bicycle for people who are new to the sport is the mountain bike, which has a fixed frame with wide tires and upright handles. Mountain bikes also have many gears（齒輪） to make it easier to climb hills. About 5 million Americans ride mountain bikes, compared with 200,000 who rode them only five years ago.
Costs range from about ＄130 for a bottom-of-the-line bicycle to more than ＄2,700 for an expensive bicycle.
Mountain biking has attracted some people who race down the sides of mountains like a bat out of hell. But most riders ride slowly and they rarely venture far from home.
The biking craze has brought an unexpected profit（盈利） to clothing and bicycle accessory（附屬品）makers. Last year, bikers paid ＄630 million for biking clothes and accessories.
Bicycling seems likely to continue its fantastic growth.
