London—coffee protects mice from radiation and could get the same way in humans, according to Indian scientists. Scientist at India’s Bhabha Atomic Research Center discovered that mice injected with caffeine (咖啡因)remained alive after high doses(剂量)of normally lethal radiation. Although the study was limited to animals, Kachadillilli George, head of the research team, believes the findings could have implications (something suggested ) for humans . “It does suggest that coffee might have some beneficial effects in protecting against radiation,” he told New Scientist magazine late last month. George and his team injected 471 mice with caffeine and left them uncovered to 7.5 grays of gamma radiation(伽玛射线),enough to kill most mice. But 25 days later 70 percent of the mice that had received 80 milligrams(毫克)of caffeine per kilogram of body weight were still alive. On the contrary all 196 mice that had been left uncovered to the same radiation but had not been given any caffeine died. 1.George and his team drew the conclusion from . A．the magazine B．their invention C．the experiment D．their experience 2.From the news, we know can be protected from radiation. A．both mice and humans B．only mice C．only humans D．neither humans nor mice 3.From paragraph 5, we know 30 percent of the mice died 25 days later. The reason was probably that . A．these mice had been given only 80 milligrams of caffeine B．these mice hadn’t been injected with caffeine C．these mice were very big and strong D．these mice hadn’t been given enough caffeine 4.Which is the best title of the article? A．Human and Mice B．New Radiation Defense—Coffee C．Deadly Radiation—Gamma Radiation D．Mice Died of Caffeine 5.In paragraph 2,the underlined word “ lethal ”means . A．causing death B．lively C．exciting D．rich
Most lives saved from sinking ferryCao Min couldn’t believe she was experiencing exactly what she had seen years ago in the film “Titanic”. Cao and her two children from Anhui Province were traveling on board the “Liaoludu 7”on February 22.They were among the first people on the ship who were rescued by lifeboats. Cao’s one-year-old son was the youngest passenger on board. The “Liaoludu 7”was traveling in the Bohai Straits(渤海海峡)from Lushun in Liaoning Province to the port city of Longkou in Shandong Province. It suddenly lost its power at 2:30 pm and tilted(倾斜)on its side. With 81 people on board, the ferry(渡船)began to sink. “I was so scared that my legs couldn’t move forward. They kept shaking even when I was asked to jump onto a “ lifeboat.” Cao recalled. Upon receiving the urgent appeal, China Marine Search and Rescue Center(中国海上搜救中心)immediately informed the State Council(国务院).The center sent eight lifeboats to the sinking ship and asked for help form the Ministry of Agriculture, the Navy and nearby fishing boats. After more than four hours of fighting against strong winds and freezing ocean water, the passengers were recovered. All but four survived. These four died after spending too long in the freezing waters, according to a spokesperson for the Beijing-based center. (From 21st Century, Mar.3, 2003) 1.How many people survived the disaster? A．4 B．81 C．85 D．77 2.Who do you think were the first people rescued? A．Women and children B．Women C．Children D．Men 3.Which of the following is Not true? A．The accident happened from Longkou in Shandong Province to Lushun in Liaoning Province. B．The fighting of the people on board against the strong winds and freezing ocean water lasted several hours. C．Cao and her children fortunately were saved. D．But for the State Council, the passengers and the crew would have lost their lives.
For years and years people have been saying that the railways are dead. “ We can do without railways.” People say…as if motorcars and planes have made the railways unnecessary. We all keep hearing that trains are slow, that they lose money, and that they’re dying .But this is far from the truth: in these days of expensive oil, the railways have become highly competitive with motorcars and planes. If you want to carry people or goods from place to place, they are cheaper than planes. And they have much in common with planes. A plane goes in a straight line and so does a railway. What is more, it takes you from the heart of a city into the heart of another. It doesn’t leave you up as a plane does, miles and miles from the city center. It doesn’t hold you up as a car does, in endless traffic jams, and a single train carry goods which a plane or a motorcar could never do. Far from being dead, the railways are very much alive. Modern railway lines give you a smooth, untroubled journey. Where else can you eat well, sleep in comfort, feel safe and enjoy the scene while you are traveling at speed at the same time? And we are only at the beginning, for we have just entered the age of super-fast trains, trains traveling at 150 miles an hour and more. Soon we will be wondering why we spent so much on motorcars we can’t use because we have not enough money to buy the oil and planes we can’t fly for the same reason.. 1.Some people think the railways are unnecessary for many reasons except that . A．planes and motorcars have taken the place of trains B．oil is expensive today C．trains are slow D．railways lose money 2.According to the writer, which of the following is Not true? A．It is cheaper to travel by train than by plane. B．The railway station is usually at the center of the city. C．When you get off the plane you will find yourself right in the city center. D．No motorcar or plane can carry as many goods as a train does. 3.The writer thinks that the railways, far from being dead, are very much alive because . A．we can have a smooth and untroubled journey B．we’ll not have enough money to fly in planes C．we can now travel in super-fast train D．all of the above 4.The best title for this passage may be” ” A．Not the End but the Beginning B．Which is the Best: Train, Motorcar or Plane C．Trains are More Competitive than Motorcars or Planes D．Oh, Super-fast Trains
I believe honesty is one of the greatest gifts. I know they call it a lot of fancy names these days, like 36_ and straightforward .And it’s still what 37 a man a good citizen .This is my secret ,and I try to live by . I’ve been in the taxi business for thirty-five year, 38 there is a lot about it that is not so good. Taxi drivers have to be rough and tumble (乱作一团) fellows to be able to take it in New York. You’ve got to be 39 to fight the New York traffic eight hours a day . Because taxi drivers are tough, people get the 40 impression that they are bad .Taxi drivers are just like other people. Most of them will act as 41 fellows. You read in the papers almost every week 42 a taxi driver turns in money or jewels or like that people leave in their 43 . If they weren’t hones, you wouldn’t be reading those stories in the papers. One time .I found an emerald (翡翠的) ring in my car. I remembered helping a lady with a lot of suitcases that day , so I went back to where I had 44 . It took me almost two days to wait for her in order to return her 45 to her. I didn’t get much as “thank you”. 46 I felt good because I had done what was right. I think I felt better than she 47 . I was born and raised in Ireland until I was nineteen years old. I came to this country in 1913 where I 48 several jobs to earn a few dollars before joining the army in Word War I. After being discharged (退伍), I bought my own car and have owned one ever since. It hasn’t been too easy 49 , but my wife takes care of our money and we have a good bit 50 for a rainy day (一时之需). In all my years of driving a taxi, I have never had 51 with the public, not even with drunks. Even if they get a little headstrong (顽固的) once in a while, I just agree with them and then they behave themselves. People ask me about tips. As far as I know, 52 everyone will give you something , because most Americans are 53 generous . I always try to be nice to everyone, whether they 54 or not. I believe in God and try to be a good member of my parish (教区 ). I try to act toward others like I think god wants me to act.

Bushwick is a tough place to grow up. This part of Brooklyn, in New York City, has a lot of crime. More than half of its 100,000 residents rely on aid from the government. Only 50% of students at Bushwick High School graduate in four years. Some people might say, “We should help these poor kids who have so many challenges.” But Malaak Compton-Rock looks at the teens in Bushwick and says, “ Go to help kids who have even bigger challenges than you do.” She believes that once young people see the power they have to make things better, they can handle their own problems more easily. So her service group, the Angel Rock Project, took 30 Bushwick kids to Soweto, in South Africa, to help poor families there. Soweto is a township outside the city of Johannesburg. The effort, called Journey for Change, aims to show that any kid can change the world. “Kids in Bushwick face pressure to drop out of school or become involved in gangs and drugs.” Says Compton-Rock. “We want them to live a life of purpose and service.” In Soweto, many parents have died of AIDS, a deadly disease. When that happens, a grandparent or a child must lead the family. The Bushwick volunteers helped such families. They tended vegetable gardens, cared for babies and bought groceries. “The saddest thing was when we visited an orphanage (孤儿院) and I helped a little boy who had been abandoned because he had HIV, the virus that causes AIDS,” says Queen Clyde, 12. “It‘s been good to be on this trip. But what’s also important is what we do when it’s finished. That’s what counts.” “ I never appreciated what I had until I saw some people who had nothing,” says Sadara Lewis, 12 “It’s really changed my attitude. I want to make a difference.” The trip was two weeks long. But the kids, aged 12 to 15, will spend all year speaking about their experience, fund-raising and more. 1.What’s the main idea of the first paragraph? A．Bushwick is the poorest place in New York City. B．Bushwick still needs more care from the government. C．It is children who suffer most in New York City. D．Children in Bushwick are living in a bad situation. 2.In Compton-Rock’s opinion, the Bushwick kids __________. A．have few challenges B．should be kept out of schools C．can learn to deal with their own problems by helping others D．are living much better than people in Africa 3.Compared to Bushwick kids, some children in Soweto __________. A．may have bigger challenges B．receive no care from the government C．are much more independent D．are able to lead the family 4.According to the passage, “Journey for Change” can be best seen as the saying “________”. A．God helps those who help themselves B．saying and doing are two things C．one stone kills two birds D．a friend in need is a friend indeed 5.From the passage we know that __________. A．there are few students in Bushwick High School B．the trip to Soweto will have a long influence in spite of its short time. C．most children are suffering from AIDS in Soweto D．kids with HIV will be abandoned in Soweto
It was Thanksgiving morning and in the crowded kitchen of my small home I was busy preparing the traditional Thanksgiving turkey when the doorbell rang. I opened the front door and saw two small children in rags huddling together. “Any old papers, lady?” asked one of them. I was busy. I wanted to say “no” until I looked down at their feet. They were wearing thin little sandals, wet with heavy snow. “Come in and I’ll make you a cup of hot cocoa.” They walked over and sat down at the table. Their wet sandals left marks upon the floor. I served them cocoa and bread with jam to fight against the cold outside. Then I went back to the kitchen and started again on my household budget. The silence in the front room struck me. I looked in. The girl held the empty cup in her hands, looking at it. The boy asked in a flat voice, “Lady, are you rich?” I looked at my shabby slipcovers. The girl put her cup back in its saucer carefully and said, “Your cups match your saucers.” Her voice was hungry with a need that no amount of food could supply. They left after that, holding their bundles of papers against the wind. They hadn’t said “Thank you.” They didn’t need to. They had reminded me that I had so much for which to be grateful. Plain blue china cups and saucers were only worth five pence. But they matched. I tasted the potatoes and stirred the meat soup. Potatoes and brown meat soup, a roof over our heads, my man with a good steady job—these matched, too. I moved the chairs back from the fire and cleaned the living room. The muddy prints of small sandals were still wet upon my floor. Let them be for a while, I thought, just in case I should begin to forget how rich I am. 1.Two children came to the writer’s front door because _________________. A．it was Thanksgiving Day B．they were beggars C．they wanted old papers D．they wanted a cup of cocoa 2.Why did the writer let the children in? A．She showed great pity on them B．She had old papers to sell C．She wanted to invite them to her Thanksgiving feast D．She wanted them to see how rich she was 3.The girl thought the writer was rich perhaps because ________________. A．she saw that the lady’s room was comfortable B．she saw the cups matched the saucers C．the writer’s slipcovers were very new D．the writer was preparing a big meal while she was too hungry. 4.From the passage, we can infer that whether you are rich depends on ________. A．how much money you have had B．how you feel about your life C．how you have helped others D．what job your husband is doing 5.The writer left the muddy prints of small sandals on the floor for a while to ____________. A．show her husband that someone had come B．remind her that she had helped two children C．remind her that she was very rich in the neighborhood D．remind her how life should be
When an ant dies, other ants move the dead insect out. Sometimes, the dead ant get moved away very soon—within an hour of dying. This behavior is interesting to scientists, who wonder how ants know for sure—and so soon—that another ant is dead. One scientist recently came up with a way to explain this ant behavior. Dong-Hwan Choe is a biologist. Choe found that Argentine ants have a chemical on the outside of their bodies that signals to other ants, “I’m dead—take me away.” But there’s a twist to Choe’s discovery. Choe says that the living ants—not just the dead ones—have this death chemical. In other words, while an ant crawls around, perhaps in a picnic or home, it’s telling other ants that it’s dead. What keeps ants from dragging away the living ants？Choe found that Argentine ants have two additional chemicals on their bodies, and these tell nearby ants something like, “Wait—I’m not dead yet.” So Choe’s research turned up two sets of chemical signals in ants: one says, “I’m dead,” and the other set says, “I’m not dead yet.” Other scientists have tried to figure out how ants know when another ant is dead. If an ant is knocked unconscious, for example, other ants leave it alone until it wakes up. That means ants know that unmoving ants can still be alive. Choe suspects that when an Argentine ant dies, the chemical that says “Wait-I’m not dead yet” quickly goes away. Once that chemical is gone, only the one that says “I’m dead” is left. “It’s because the dead ant no longer smells like a living ant that it gets carried to the graveyard, not because its body releases(释放) new unique chemicals after death,” said Choe. When other ants detect the “dead” chemical without the “not dead yet” chemical, they drag away the body. Understanding this behavior may help scientists figure out how to stop Argentine ants from invading new places and causing problems. Choe would like to find a way to use the newly discovered chemicals to spread ant killer to Argentine ant nests. The ants’ removal behavior is important to the overall health of the nest. “Being able to quickly remove dead individuals and other possible sources of disease is extremely important to all animals living in societies, including us,” says Choe. “Think about all the effort and money that we invest daily in waste management.” 1.The underlined word “twist” in Paragraph 3 means . A．an unexpected change B．a clear mistake C．an important key D．a shocking conclusion 2.Ants judge whether another one is dead or not depending on . A．the sense of taste B．the sense of smell C．the sense of touch D．the sense of sight 3.The result of the research can be used to . A．kill troublesome pests B．solve the problem of endangered species C．prevent further expansion of the ants’ territory D．keep the balance of nature 4.Why is it important to remove dead individuals? A．Because it is easier to manage the living. B．Because it can save money to deal with the waste. C．Because it can provide more space for the living. D．Because it can keep the living from suffering disease. 5.What might be the best title of the text? A．Dead or living? It is easy to judge B．Pulling away the dead ants is a difficult task C．Ant nests have great undertaking capacity D．Leaving it alone or taking it away? Ants feel puzzled
The accident at Lake Sherwood was in our backyard. An SUV(运动型多用途车)had gone off the road，down a hill, and collided with a tree. When we heard the wreck, I remembered to say “call 911”. My family was the first on the scene. Nick, my son, was on the cell phone with 911. He saw a friend who was a victim in the crash who was a 15 years old girl who was badly disfigured and had died instantly. It was a terrible scene. There had been six people in the truck, all between 15 and 17 years old. My husband and I checked all the victims, and I picked one who was conscious and stayed with him. I talked with him and had him lay on the ground. When I asked him if he was hurt, he said he was sore all over. When help arrived, they asked me to stay and continue working with them. I did as Debbie Romine, .my instructor, said in class, and did what they wanted. They even said thank you before they left. The sheriff deputies came by Saturday night to get our statements and play the 911 tape back, so Nick could identify all the voices in the background. They said over and over that the way he handled the call was the best they had heard in a long time. He was calm and worked with them even when he saw his friend who had died. The Sheriff’s Department is sending some people over to help us work through our emotions. The first aid and CPR course I took in January really helped me. I just didn’t expect to put it to good use so soon. Pennyd. Miller Kansas State Dept of Education,Topeka 1.According to the passage, in case of an emergence, people should dial_______________.
