If you see a group of people dancing and singing on the street or in the railway station, you don't need to feel surprised. They are a flash mob(暴民). Who are they? Are they mobs? Don't be confused by their name. Actually, a flash mob is a group of people who gather suddenly in a public place, do something unusual for a brief period of time, and then quickly disappear.
They are usually organized with the help of the Internet or other digital communications networks. The messages may be sent to friends, who send to more people. At a predetermined time, they gather and perform some activities such as exchanging books, coming together to look at the sky, waving their hands and yelling something at the top of their voice for 30 seconds. Then, they quickly disappear before the police can arrive. Using mobile phones, the flash mob can change its place if the first one has been cancelled for any reason.
Bill Wasik, senior editor of Harper's Magazine, organized the first flash mob in Manhattan in May 2003 and the first successful flash mob gathered on June 3,2003. Wasik claimed that he created the flash mob as a social experiment designed to laugh at fashion seekers and stress the cultural atmosphere of wanting to be an insider or part of “the next big thing”．
Flash mob gatherings can sometimes shock people. Such an activity might seem amusing and magical, but it also might frighten people who are not aware of what is taking place. Undoubtedly, flash mob can serve as good political tools and have great potential, such as using to advertise a product.

A dog who chewed off his owner’s infected toe（脚趾）while he was passed-out drunk has been called a lifesaver. Jerry Douthett had been out drinking when his dog Kiko bit off a large part if his big toe. His wife, Rosee, rushed him to hospital where tests showed the 48-year-old musician had dangerous high blood-sugar levels. Doctors told him his toe would have had to be cut off anyway.
Mr Douthett said he had refused to get medical advice despite his toe being swollen for months. “I was hiding it from people, Rosee included,” he said. “It smelled , and I look back now and realize every time we’d visit someone with a dog, their dog would smell all over my foot.”
The night before Mr Douthett had agreed to see a doctor, he passed out at home after going out drinking. He said, “I woke up and the dog was lying along side by foot. I said, ‘Ah, there’s blood everywhere.’ I ran to the bathroom and started to scream.”
However, he believes Kiko could sense the disease coming from his big toe. “He’s a hero,” Mr Douthett said. “It wasn’t an aggressive attack. He just ate the infection. He saved my life. He ate it. I mean, he must have eaten it, because we couldn’t find it anywhere else in the house. I look down. There’s blood all over, and my toe is gone.”
Before the operation, Mr Douthett asked a nurse, “Is there any chance I can get whatever’s left of my toe, so I can give it to Kiko as a treat?” Kiko is still with the family but is under observation by authorities..Mr Douthett didn’t want to get medical treatment because ______ .
| A．he didn’t know about his disease at all |
| B．he was unwilling to let others know about his disease |
| C．doctors had no good ways to treat his bad toe |
| D．his wife advised him not to do that |
.From Paragraph 3 we can infer that ______ .
| A．Rosee managed to persuade her husband to go to hospital |
| B．Mr Douthett made his big toe worse by frequent drinking |
| C．Mr Douthett didn’t know his toe was chewed off at first |
| D．it is dangerous for people to let pet dogs sleep in the bedrooms |
.What did Mr Douthett think of his dog ?
| A．It was clever and brave. |
| B．It never attacked healthy people. |
| C．It was a cruel but helpful dog. |
| D．It was a dangerous dog in fact. |
Can peo
ple change their skin colour without suffering like pop king Michael Jackson? Perhaps yes. Scientists have found the gene that determines skin colour.
The gene comes in two versions, one of which is found in 99 per cent of Europeans. The other is found in 93 to 100 per cent of Africans, researchers at Pennsylvania State University report in the latest issue of Science.
Scientists have changed the colour of a dark-striped zebrafish to uniform gold by inserting a version of the pigment(色素) gene into a young fish. As with humans, zebrafish skin colour is determined by pigment cells, which contain melanosomes(黑色素). The number, size and darkness of melanosomes per pigment cell determines skin colour.
It appears that, like the golden zebrafish, light-skinned Europeans also have a mutation(变异) in the gene for melanosome production. Thi
s results in less pigmented skin.
However, Keith Cheng, leader of the research team, points out that the mutation is dif ferent in human and zebrafish genes.
Humans acquired dark skin in Africa about 1.5 million years ago to protect bodies from ultra-violet rays of the sun(太阳光紫外线), which can cause skin cancer.
But when modern humans leave Africa to live in northern latitudes, they need more sunlight on their skin to produce vit amin D. So the related gene changes, according to Cheng.
Asians have the same version of the gene as Africans, so they pr obably acquired their light skin through the action of some other gene that affects skin colour, said Cheng.
The new discovery could lead to medical treatments for skin cancer. It also could lead to research into ways to change skin colour without damaging it like chemical treat
ment did on Michael Jackson.. The passage mainly tells us that ________.
| A．people can not change their skin colour without any pain |
| B．the new discovery could lead to search into ways to change skin colour safely |
| C．pop king Michael Jackson often changed his skin colour as he liked |
| D．scientists have found out that people’s skin colour is determined by the gene |
. Scientists have done an experiment on a dark-striped zebra fish in order to ________.
| A．find the different genes of humans’ |
| B．prove the humans’ skin colour is determined by the pigment gene |
| C．find out the reason why the Africans’ skin colour is dark |
| D．find out the ways of changing peopl’s skin colour |
. The reason why Europeans are light-skinned is probably that ________.
| A．they are born light-skinned people |
| B．light-skinned Europeans have mutation in the gene for melanosome production |
| C．they have fewer activities outside |
| D．they pay much attention to protecting their skin |
For many people in the US，sports are not just for fun. They’re almost a “religion”．Thousands of sports fans buy expensive tickets to watch their favorite teams and athletes play in person .Other fans watch the games at home，sticking to their TV sets，never missing a game. Many a wife becomes a “sports widow” during her husband’s favorite season. Americans’ devotion to sports has created a new class：professional athletes. Sports stars often receive milliondollar salaries. Some even make big money by appearing in advertisements for soft drinks，shoes and almost everything.
Sports are an important part of American culture. Throughout their school life，Americans learn to play many sports. Many students try out
for the school teams. Athletic events at universities attract scores of fans and benefit the whole community. Many people also enjoy noncompetitive activities，like hiking，cycling，horseback riding，camping or hunting.
Many sports were imported from other countries. Europeans brought tennis，golf，bowling and boxing to America .Football and baseball came from other Old World games. Only basketball has a truly American origin. Americans export sports fever as well. Satellites broadcast games to sports fans around the globe. NBA is a good example. The names of American superstars like basketball great Michael Jordan have become household words all over the world.．Many a wife becomes a “sports widow” in the US probably because________.

Many years ago my
student asked me the question, "Mrs. Kindred, why do you teach?" Without taking time to reflect, I answered, "Because someday I might say something that might make a difference in someone's life." Even though I was sincere, that wasn't a very good answer and my student didn't let it slide.
"Let me get this straight," he said, "You went to college for four years so you could come here every day because you have the hope that someday you might say something that will influence someone?" He shook his head as if I were cra zy and walked away looking confused . I'm one of those people who look back and wish they had said something smart or witty, or swift.
Even though that particular student might no longer wonder why I teach, there are days when I wonder. On those days, I remind myself of the real reasons I teach: It's in my blood. My mother was my most influential teacher, and she was a 6th grade reading teacher until her death in 1990. She instilled(逐渐灌输) in me a love of reading and the knowledge that education opens doors.
Teaching is a way to make a difference. If you throw a stone in a pond the ripples go on and on until they reach the shore. You can't have ripples without a "stone." Good teachers throw stones that make a positive difference, and that's what I strive to do. I genuinely love teenagers. I want to share with others what I know and what I have learned through the years. Life is full of ups and downs, and if I can help students avoid some potholes on the road of life, I want to do so. If they'll allow me to celebrate their victories with them, I want to do too.
Teaching isn't for everyone, but I know I made the right career choice.. Why did the student continue to ask the question about the writer’s being a teacher?
| A．Because he thought her answer was unbelievable. |
| B．Because the writer was insincere. |
| C．Because the student was naughty. |
| D．Because the answer was difficult to understand. |
. What do you think of the writer?
| A．Stupid. | B．Honest. | C．Insincere. | D．Polite. |
. According to the text, which of the following is NOT true?
| A．The writer’s mother has the greatest influence on her. |
| B．The writer’s answer made the student confused. |
| C．In the writer’s opinion, some people in the world are unfit to teach. |
| D．The writer annoyed the student who asked the question. |
. We can infer from the text that _________.
| A．the writer was also a good teacher in school |
| B．the writer often plays with her students beside a pond |
| C．the writer devotes herself to teaching and her students. |
| D．the writer often accompanies the students on their way home |
. What’s the main idea of the text?
| A．A student’s silly question. | B．A good teacher who likes students. |
| C．A confused student. | D．The reason why I teach. |
