Although we already know a great deal about flu, and although the World Health Organizations is constantly collecting detailed information from its chain of flu reference laboratories throughout the world, it is extremely difficult for epidemiologists, who study infectious diseases, to predict when and where the next flu epidemic will occur, and how serious it will be.
There are three kinds of flu virus, known as A, B and C. flu C virus is relatively stable and causes mild infections that do not spread far through the population. The A and B types are unstable, and are responsible for the epidemics that cause frequent concern. Following any virus attack, the human body builds up antibodies (抗体) which can be changed into immunity to that type of virus but a virus with the ability to change its character is able to bypass this protection. Variability(可变性) is less developed in the flu B virus, which affects only human beings. As flu B virus may cause a widespread epidemic but will have little effect if introduced into the same community soon afterwards, since nearly everyone will have built up antibodies and will be immune. The flu A virus, which affects animals also, is extremely unstable and is responsible for some of the worst outbreaks of the disease, such as the world epidemic, of 1918&1919, when about half the world's population were infected and about twenty million people died, some from pneumonia caused by the virus itself and some from secondary complication caused by bacteria. Accurate prediction is difficult because of the complication of the factors. A particular virus may be related to one to which some of the population have partial involved immunity. The extent to which it will spread will depend on factors such as its own strength, or virulence (病毒性), the ease with which it can be transmitted and the strength of the opposition it encounters (遇到). Scientists, however, have a reliable general picture of the world situation.

Christopher Thomas, 27, was a writer by night and a teacher by day when he noticed he was always tired and was losing weight fast. Diagnosed with diabetes(糖尿病), Thomas would need to inject himself with insulin(胰岛素) three times a day for the rest of his life or risk nerve damage, blindness, and even death. And if that weren't bad enough, he had no health insurance.
After a month of feeling upset, Thomas decided he'd better find a way to fight back. He left Canton, Michigan for New York, got a job waiting tables, nicknamed himself the Diabetic Rockstar , and created diabeticrockstar.com, a free online community for diabetics and their loved ones—a place where over 1,100 people share personal stories, information, and resources.
Jason Swencki’s son, Kody, was diagnosed with type diabetes at six. Father and son visit the online children's forums(论坛) together most evenings. "Kody gets so excited, writing to kids from all over," says Swencki, one of the site's volunteers. "They know what he's going through, so he doesn't feel alone."
Kody is anything but alone: Diabetes is now the seventh leading cause of death in the United States, with 24 million diagnosed cases. And more people are being diagnosed at younger ages.
These days, Thomas's main focus is his charity(慈善机构), Fight It, which provides medicines and supplies to people—225 to date—who can't afford a diabetic's huge expenses. Fight-it.org has raised about $23,000—in products and in cash. In May, Thomas will hold the first annual Diabetic Rockstar Festival in the Caribbean.
Even with a staff of 22 volunteers, Thomas often devotes up to 50 hours a week to his cause, while still doing his full-time job waiting tables. "Of the diabetes charities out there, most are putting money into finding a cure," says Bentley Gubar, one of Rockstar's original members. "But Christopher is the only person I know saying people need help now."Which of the following is true of Christopher Thomas?
A. He needs to go to the doctor every day. |
B. He studies the leading cause of diabetes |
C. He has a positive attitude to this disease. |
D. He encourages diabetics by writing articles. |
Diabeitcrockstar.com was created for _________.
A.diabetics to communicate | B.volunteers to find jobs |
C.children to amuse themselves | D.rock stars to share resources. |
The last paragraph suggests that Thomas ______.
A.works full-time in a diabetes charity |
B.employs 22 people for his website |
C.helps diabetics in his own way |
D.ties to find a cure for diabetes |
It is hardly surprising that clothing manufacturers (生产商)follow certain uniform standards for various features(特征)of clothes. What seems strange, however, is that the standard adopted for women is the opposite of the one for men. Take a look at the way your clothes button. Men’s clothes tend to button from the right, and women’s from the left. Considering most of the world’s population-men and women-are right-handed, the men’s standard would appear to make more sense for women. So why do women’s clothes button from the left?
History really seems to matter here. Button first appeared only on the clothes of the rich in the 17th century, when rich women were dressed by servants. For the mostly right-handed servants, having women’s shirts button from the left would be easier. On the other hand, having men’s shirts button from the right made sense, too. Most men dressed themselves, and a sword drawn from the left with the right hand would be less likely to get caught in the shirt.
Today women are seldom dressed by servants, but buttoning from the left is still the standard for them. Is it interesting? Actually, a standard, once set, resists change. At a time when all women’s shirts buttoned from the left, it would have been risky for any single manufacture to offer women’s shirts that buttoned the right. After all, women had grown so used to shirts which buttoned from the left and would have to develop new habits and skills to switch. Besides from the right, since anyone who noticed that would believe they were wearing men’s shirts.What is surprising about the standard of the clothing industry?
A.It has been followed by the industry for over 400 years. |
B.It is different for men’s clothing and women’s. |
C.It woks better with men than with women. |
D.It fails to consider right-handed people. |
What do we know about the rich men in the 17th century?
A.They tended to wear clothes without buttons. |
B.They were interested in the historical matters. |
C.They were mostly dressed by servants. |
D.They drew their swords from the left. |
Women’s clothes still button from the left today because.
A.adopting men’s style is improper for women |
B.manufacturers should follow standards |
C.modern women dress themselves |
D.customs are hard to change |
The passage is mainly developed by .

Some years ago, I was hired by an American bank. I received a letter from the head of the Personnel Department that started, "Dear John, I am quite pleased that you have decided to join us." That "quite" saddened me. I thought he was saying "we're kind of pleased you decided to join us although I wish we had hired someone else." Then I discovered that in American English "quite" sometimes means "very", while in British English it means "fairly".
So the first lesson about working in other countries is to learn the language and by that I don't just mean the words people speak. It is body language, dress, manners, ideas and so on. The way people do things highlights many of the differences we see between cultures(文化).
Some of these differences may be only on the surface-dress, food and hours of work-while others may be deeper and take longer to deal with. Mostly, it is just a question of getting used to the differences and accepting them, like the climate(气候),while getting on with business.
Some of the differences may be an improvement. People are more polite; the service is better; you ask for something to be done and it happens without having to ask again. However, other differences can be troubling, like punctuality(准时).If you invite people to a party at 7 o'clock your guests will consider it polite to turn up exactly on time in Germany, five minutes early in the American Midwest, an hour early in Japan, 15 minutes afterwards in the UK, up to an hour afterwards in Italy and some time in the evening in Greece. I prefer not to use the word "late" because there is nothing wrong with the times people arrive. It is simply the accepted thing to do in their own country.The author was unhappy as mentioned in Paragraph 1 because he thought______.
A.the American bank didn't think much of him |
B.the American bank might hire another person |
C.it's difficult to get used to American culture |
D.it's easy to misunderstand Americans |
The word "highlights" in Paragraph 2 probably means_____.
A.encourages | B.helps to narrow |
C.increases | D.draws attention to |
According to the author, what should we do with most cultural differences?
A.Ask the native people for help. |
B.Understand and accept them. |
C.Do things in our own way. |
D.Do in-depth research. |
When invited to a party the people who are usually punctual are______.
A.Italians | B.Germans | C.Greeks | D.the British |
While small may be beautiful, tall is just plain uncomfortable it seems, particularly when it comes to staying in hotels and eating in restaurants.
The Tall Persons Club Great Britain (TPCGB), which was formed six months ago to campaign for the needs of the tall, has turned its attention to hotels and restaurants. Beds that are too small, shower heads that are too low, and restaurant tables with hardly any leg-room all make life difficult for those of above average height, it says.
But it is not just the extra-tall whose needs are not being met. The average height of the population has been increasing yet the standard size of beds, doorways, and chairs has remained unchanged.
“The bedding industry says a bed should be six inches larger than the person using it, so even a king-size bed at 6′6″ (6 feet and 6 inches) is falling short for 25% of men, while the standard 6′3″ bed caters for less than half of the male population.” Said TPCGB president Phil Heinricy, “seven-foot beds would work fine.”
Similarly, restaurant tables can cause no end of problems. Small tables, which mean the long-legged have to sit a foot or so away from them, are enough to make tall customers go elsewhere.
Some have already taken note, however. At Queens Moat Houses′ Caledoman Hotel in Edinburgh, 6′6″beds are now put in as standard after requests for longer beds from taller visitors, particularly Americans.What is the purpose of the TPCGB campaign?
A.To provide better services. |
B.To rebuild hotels and restaurants. |
C.To draw public attention to the needs of the tall. |
D.To attract more people to become its members. |
Which of the following might be a bed of proper length according to Phil Heinricy?
A.7′2″. | B.7′ | C.6′6″ | D.6′3″ |
What may happen to restaurants with small tables?
A.They may lose some customers. |
B.They may start businesses elsewhere. |
C.They have to find easy chairs to match the tables. |
D.They have to provide enough space for the long-legged. |
What change has already been made in a hotel in Edinburgh?
A.Tall people pay more for larger beds. |
B.6′6″beds have taken the place of 6′3″beds. |
C.Special rooms are kept for Americans. |
D.Guest rooms are standardized. |
One afternoon last week, I saw three tearful children from my son's school being comforted by teachers. That morning, my 11-year-old had stomach pains, retching(干呕)into a bowl. Talking to other mothers later, I heard about other children with stomachache or difficult sleeping the night before.
What caused so much pain? Sports day. Sports day might be necessary at a highly-competitive independent school, but not at a village primary school. For the children who can fly like the wind, sports day cause no problem. For those who are overweight or just not good at sport, it is nightmare(噩梦). Even for those who enjoy running but fall halfway down the track in front of the entire school and their parents, it can prove a disease.
Why do we put our children through this annual suffering? Some may say competition is character building; or it's taking part, not winning, that's important; or that's a tradition of school life. I just felt great pity for those children in tears or in pain.
Team games at the end of sports day produced some close races, wild enthusiasm, lots of shouting - and were fun to watch. More importantly, the children who were not so fast or quick at passing the ball were hidden a little from everyone's eyes. Some of them also had the thrill of being on the winning side.
I wish that sports day could be abandoned and replaced with some other less competitive event. Perhaps an afternoon of team games, with a few races for those who want them, would be less stressful for the children and a lot more fun to watch.
