GENEVA(Reuters) -Pregnant women and other people at high risk should be vaccinated(注射疫苗) against the H1N1 swine flu virus as the cold weather begins to bite in the northern hemisphere(半球), the World Health Organization(WHO) said on Tuesday.
It voiced concern that some vulnerable(弱势的) people don’t have access to the pandemic(传染病) vaccine, which the WHO stressed had not caused any unusual side effects in hundreds of thousands of people to have received it worldwide so far.
“Certainly th e fact that the vaccine isn’t being used by those who would have access to it and who would be in priority risk groups is of concern, yes,” WHO spokesman Gregory Hartl told a news briefing.
At least 5, 712 people have died from the swine flu virus, according to the United Nations agency. Health workers, pregnant women and people with conditions such as asthma are deemed at greatest risk and should be top priority for getting the shot.
“We have seen many, many examples of people in high risk groups such as pregnant women who have very severe disease or outcomes. These outcomes could be in all likelihood avoided if one were to get vaccinated,” Hartl said.
Unlike seasonal flu, which is most dangerous to the elderly, H1N1 is hitting younger adults and children especially hard.
The WHO recommends a single vaccine dose for protecting adults against H1N1. It has also urged governments to consider giving a single dose to as many children under age 10 as possible, but says more research is needed into child dosages.
In the United States, studies show that children under the age of 9 will need two doses of the vaccine to be fully protected, officials there said on Monday.
Parts of North America and Europe have already crossed the epidemic (流行病) threshold( 开始了), ahead of the normal influenza season which peaks in January-February for the northern hemisphere, WHO says.

A. Whether the vaccine has side effect or not.
B. How many people are infected by the H1N1 swine flu virus.

53. In paragraph 4, “getting the shot” means ____________.
A. being shot B. being vaccinated C. being cured D. getting killed
54. What can we learn from this passage?

A black hole is a place in space where gravity pulls so much that even light cannot get out. The gravity is so strong because matter has been squeezed into a tiny space. This can happen when a star is dying.
Because no light can get out, people can’t see black holes. Space telescopes with special tools can help find black holes. The special tools can see how stars that are very close to black holes act differently from other ones.
Black holes can be big or small. Scientists think the smallest black holes are as small as just one atom. These black holes are very tiny but have the mass of a large mountain. Mass is the amount of matter, or “staff”, in an object.
Another kind of black hole is called “stellar”(星球黑洞). Its mass can be up to 20 times more than the mass of the sun. There may be many stellar mass black holes in Earth’s galaxy. Earth’s galaxy is called the Milky Way.
The largest black holes are called “supermassive”(超大质量黑洞). These black holes have masses that are more than one million suns together. Scientists have found proof that every large galaxy contains a supermassive black hole at its center. The supermassive black hole at the center of the Milky Way galaxy has a mass equal to about four million suns and would fit inside a very large ball that could hold a few million Earths.
Scientists think the smallest black holes formed when the universe began. Stellar black holes are made when the center of a very big star falls in upon itself, or falls apart. When this happens, it exploded part of the star into space. Scientists think supermassive black holes were made at the same time as the galaxy they are in.
A black hole can not be seen because strong gravity pulls all of the light into the middle of the black hole. But scientists can see how the strong gravity affects the stars and gas around the black hole. Scientists can study stars to find out if they are flying around, or orbiting a black hole.
When a black hole and a star are close together, high-energy light is made. This kind of light cannot be seen with human eyes. Scientists use satellites and telescopes in space to see the high-energy light. The gravity of a black hole may become so strong that light cannot get out when ____________.
| A．the star is going to die |
| B．special tools are used on it |
| C．other stars come close to it |
| D．it is seen from the space telescopes |
According to the passage, which of the following is NOT true?
| A．A black hole can be very tiny but extremely heavy. |
| B．The gravity of a black hole holds all light in its center. |
| C．Scientists observe high-energy light through their own eyes. |
| D．Some small black holes came into being as early as the universe. |
Which can be inferred from the passage?
| A．Every galaxy must have a black hole. |
| B．A galaxy is the center of the universe. |
| C．A galaxy consists of a large group of stars and planets. |
| D．Earth’s galaxy is called the Milky Way. |
What does the last sentence in Paragraph 5 suggest?
| A．Neither the sun nor the earth is as heavy as a black hole. |
| B．There is only one supermassive black hole at the center of the Milky Way. |
| C．The supermassive black hole had existed before the Milky Way was formed. |
| D．There is a reason why the large black holes are called “supermassive”. |
The last two paragraph mainly focus on the question of _________.
| A．what a black hole is |
| B．how black holes form |
| C．how big black holes are |
| D．how scientists know about black holes |
A primary school in UK has banned Valentine’s Day cards because of concerns that young pupils spend too much time talking about boyfriends and girlfriends.
Ashcombe Primary School in WestonSuperMare，Somerset，has told parents that cards declaring love can be“confusing” for children under the age of 11，who are still emotionally and socially developing. In this month’s newsletter(通讯)，Peter Turner，the head teacher，warned that any cards found in school would be confiscated(没收)．He wrote：“We do not wish to see any Valentine’s Day cards in school this year. Some children and parents encourage a lot of talk about boyfriends and girlfriends. We believe that such ideas should wait until children are mature enough emotionally and socially to understand the commitment involved in having or being a boyfriend or girlfriend.”Mr.Turner said any families wanting to support the Valentine’s Day idea should send cards in the post or deliver them to home addresses by hand.
His views were endorsed by Ruth Rice,46，who has twins Harriet and Olivia at the school. She said，“Children at that age shouldn’t really be thinking about Valentine’s Day，they should be concentrating on their schoolwork.”They are at an age when they are impressionable(易受影响的)and most parents including myself are with Mr.Turner. “She added that the cards cause” too much competition. If someone gets a card and another doesn’t，then someone will be disappointed.
However，Rajeev Takyar,40，who has two children Jai,11，and Aryan，five，at the school，said he was “outraged”．He said，“There are schools that have banned conkers(栗子游戏)and snowballs，and now Valentine’s Cards.”I think banning the cards stops children from having social skills. How are they going to learn about relationships otherwise？It’s ridiculous. Alec Suttenwood，father of three children，said of the ban：“It’s totally ridiculous. Young children just send the cards to each other as friends and to their parents. It’s just a bit of harmless fun. There is no difference between this and Mother’s or Father’s Day.”Which of the following is the best title?
| A．Ban on Valentine’s Day cards at school is well received. |
| B．Ban on Valentine’s Day cards at school causes argument. |
| C．British children spend too much time talking about love. |
| D．A British high school bans Valentine’s Day cards. |
The underlined word “endorsed” means________.
| A．criticized | B．quoted |
| C．disapproved | D．approved |
What do you know about Harriet and Olivia?
| A．They will send Valentine’s Day cards this year. |
| B．They are strongly against the school’s decision. |
| C．They are of the same age. |
| D．They are the children of Rajeev Takyar. |
According to Rajeev Takyar，________.
| A．sending Valentine’s Day cards helps develop children’s social skills |
| B．banning Valentine’s Day cards will benefit children |
| C．the cards cause too much competition among children |
| D．children are too young to talk about love |

It would be pleasant to believe that all young girls in the past got married for romantic reasons; but the fact is that many of them regarded marriage as their only chance to gain independence from their parents, to have a provider, or to be assured of a good place in society. A couple of generations ago, an old maid of twenty-five did not have much to look forward to, she was more or less fated to remain with her parents or to live in some relative’s home where she would help with the chores and the children. Not so any more. In the first place, women remain young much longer than they used to, and an unmarried woman of twenty-eight or thirty does not feel that her life is over. Besides, since she is probably working and supporting herself, she is free to marry only when and if she chooses. As a result, today’s women tend(倾向) to marry later in life. They have fewer children-or none at all—if they prefer to devote themselves to their profession. The result is a decline in the birthrate.
The new role that women have developed for themselves has changed family life. Children are raised differently; they spend more time with adults who are not their parents: baby sitters, day-care center personnel, relatives, or neighbors. Whether they gain or lose in the process is a hotly debated question. Some child experts believe that young children must spend all their time with their mother if they are to grow sound in body and mind. Others think that children get more from a mother who spends with them “quality time” (a time of fun and relaxation set aside for them) rather than hours of forced and unhappy baby sitting. And many child psychologists point out that children kept in day-care centers every day are brighter than those raised at home. No matter what it is, one thing about child-raising to be certain of is that the longer the child is with the mother, the better.It can be concluded from the passage that______.
| A．women today have developed a new role in family life |
| B．the birthrate is declining as a result of women’s pursuit (追求) of careers |
| C．women have always been dependent on their parents even after marriage |
| D．children must spend all their time with their mother if they are to grow sound |
The change in women’s attitude towards marriage results in all of the following EXCEPT _________.
| A．more and more women quit (leave) jobs to take care of their children at home |
| B．women today tend to marry later than they did |
| C．women have less time to raise children |
| D．more and more families remain childless |
People have different opinions over the question as to______.
| A．how children should be raised |
| B．where children should be raised |
| C．whether children should stay with their parents |
| D．how long children should stay with their parents |
The author suggests that______.
| A．working women should not have children |
| B．children should be kept in day-care centers all the time |
| C．young children should stay with their mother as long as possible |
| D．women should leave their work to look after their children at home |
The famous director of a big and expensive movie planned to film a beautiful sunset over the ocean, so that the audiences could see his hero and heroine in front of it at the end of the film as they said goodbye to each other for ever. He sent his camera crew (摄制组) out one evening to film the sunset for him.
The next morning he said to the men, “Have you provided me with the sunset?”
“No, sir.” The men answered.
The director was angry. “Why not?” he asked.
“Well, sir,” one of the men answered, “we are on the east coast here, and the sun sets in the west. We can get a sunrise over the sea, if necessary, but not a sunset.”
“But I want a sunset!” the director shouted.” Go to the airport, take the next flight to the west coast, and get one.”
But then a young secretary had an idea,” Why don’t you photograph a sunrise,” she suggested, “and then play it backwards? Then it would look like a sunset.” “That’s a good idea!” the director said. Then he turned to the camera crew and said,” Tomorrow morning I want you to get me a beautiful sunrise over the sea.”
The camera crew went out early the next morning and filmed a bright sunrise over the beach in the middle of the beautiful bay(海湾).Then at nine o’clock they took it to the director. “Here it is, sir.” They said and gave it to him. He was very pleased.
They all went to the studio. “All right,” the director explained, “now our hero and heroine are going to say goodbye. Run the film backwards so that we can see the ‘sunset’ behind them.”
The “sunset” began, but after a quarter of a minute, the director suddenly put his face in his hands and shouted to the camera crew to stop.
The birds in the film were flying backwards, and the waves on the sea were going away from the beach.One evening, the director sent his camera crew out______.
