The first robot rover to land on the Moon in nearly 40 years, China's Jade Rabbit, has begun sending back photos, with shots of its lunar lander(登月飛行器). Jade Rabbit rolled down a ramp lowered by the lander and on to the volcanic plain known as Sinus Iridum at 04:35 Beijing time on Saturday (20:35 GMT).It moved to a spot a few metres away, its historic short journey recorded by the lander. On Sunday evening the two machines began photographing each other. A Chinese flag is clearly visible on the Jade Rabbit as it stands deployed on the Moon's surface.
Ma Xingrui, chief mander of China's lunar programme, declared the mission (任務(wù))a “plete success”. The first soft landing on the Moon since 1976 is the latest step in China's ambitious space programme, says BBC science reporter Paul Rincon.
The lander will operate there for a year, while the rover is expected to work for some three months. The Chang'e3 mission landed some 12 days after being launched atop a Chinesedeveloped Long March 3B rocket from Xichang in the country's south. The official Xinhua news service reported that the lander began its descent(下降)on Saturday just after 13:00 GMT, touching down in Sinus Iridum (the Bay of Rainbows) 11 minutes later. “I was lucky enough to see a prototype rover(原型月球車) in Shanghai a few years ago it's a wonderful technological achievement to have landed,” Prof Andrew Coates, from UCL's Mullard Space Science Laboratory, told BBC News.
Chang'e3 is the third unmanned rover mission to touch down on the lunar surface, and the first to go there in more than 40 years. The last was an 840kg (1,900lb) Soviet vehicle known as Lunokhod2, which was kept warm by polonium(釙)210. But the sixwheeled Chinese vehicle carries a more sophisticated payload(復(fù)雜的有效負(fù)荷), including groundpenetrating radar which will gather measurements of the lunar soil and crust.

It is difficult for doctors to help a person with a damaged brain. Without enough blood, the brain lives for only three to five minutes. More often the doctors can't fix the damage. Sometimes they are afraid to try something to help because it is dangerous to work on the brain. The doctors might make the person worse if he operates on the brain.
Dr. Robert White, a famous professor and doctor, thinks he knows a way to help. He thinks doctors should make the brain very cold. If it is very cold, the brain can live without blood for 30 minutes. This gives the doctor a longer time to do something for the brain.
Dr. White tried his idea on 13 monkeys. First he taught them to do different jobs, then he operated on them. He made the monkeys' blood go through a machine. The machine cooled the blood. Then the machine sent the blood back to the monkeys' brains. When the brain's temperature was 10°C, Dr. White stopped the blood to the brain. After 30 minutes he turned the blood back on. He warmed the blood again. After their operations the monkeys were like they had been before. They were healthy and busy. Each one could still do the jobs the doctor had taught them.
1.The biggest difficulty in operating on the damaged brain is that _______.
A. the time is too short for doctors
B. the patients are often too nervous
C. the damage is extremely hard to fix
D. the blood-cooling machine might break down
2.The brain operation was made possible mainly by _______.
A. taking the blood out of the brain
B. trying the operation on monkeys first
C. having the blood go through a machine
D. lowering the brain' s temperature
3.With Dr. White's new idea, the operation on the damaged brain _______.
A. can last as long as 30 minutes
B. can keep the brain' s blood warm
C. can keep the patient' s brain healthy
D. can help monkeys do different jobs
4.What is the right order of the steps in the operation?
a. send the cooled blood back to the brainb. stop the blood to the brain
c. have the blood cooled downd. operate on the brain
A. a,b,c,d B. c,a,b,d C. c, b, d, a D. b, c, d, a

I lost my sight when I was four years old by falling off a box car in a goods yard in Atlantic City and landing on my head. Now I can dimly remember the brightness of sunshine and what color red is. It would be wonderful to see again, but a calamity(大災(zāi)難) can do strange things to people. It occurred to me the other day that I might not have come to love life as I do if I hadn't been blind. I believe in life now. I am not so sure that I would have believed in it so deeply, otherwise. I don't mean that I would prefer to go without my eyes. I simply mean that the loss of them made me appreciate the more what I had left.
Life, I believe, asks a continuous series of adjustments to reality. In spite of the fact the adjustment is never easy, I had my parents and teachers to help. The hardest lesson I had to learn was to believe in myself. If I hadn't been able to do that, I would have collapsed and become a chair rocker on the front porch for the rest of my life. When I say belief in myself I am not talking about simply the kind of self confidence that helps me down an unfamiliar staircase alone. That is part of it. But I mean something bigger than that: an assurance that I am, despite imperfections, a real, positive person; that there is a special place where I can make myself fit.
It took me years to discover and strengthen this assurance. It had to start with the most elementary things. Once a man gave me an indoor baseball. I thought he was laughing at me and I was hurt. “I can't use this.” I said. “Take it with you,” he urged me, “and roll it around.” The words stuck in my head. “Roll it around!” By rolling the ball I could hear where it went. This gave me an idea how to achieve a goal I had thought impossible: playing baseball.
All my life I have set ahead of me a series of goals and then tried to reach them, one at a time. I had to learn my limitations. It was no good to try for something that I knew at the start was wildly out of reach because that only invited the bitterness of failure. I would fail sometimes anyway but on the average I made progress.
1.We can learn from the beginning of the passage that ________.
A.the author lost his sight because of a car crash
B.the author wouldn't love life if the calamity didn't happen
C.the calamity made the author appreciate what he had
D.the calamity strengthened the author's desire to see
2.What's the most difficult thing for the author?
A.How to adjust himself to reality
B.Building up assurance that he can find his place in life
C.Learning to manage his life alone
D.To find a special work that suits the author
3.For the author, the baseball and encouragement offered by the man ________.
A.hurt the author's feeling
B.made the author puzzled
C.directly led to the change of the author's career
D.inspired the author
4.According to the passage, the author ________.
A.set goals for himself but only invited failure most of the time
B.thought that nothing was impossible for him
C.was discouraged from trying something out of reach for fear of failure
D.suggested not trying something beyond one's ability at the beginning

Nuclear power's danger to health, safety, and even life itself can be summed up in one word: radiation.
Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.
At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no levels of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years.
This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated(輻射)and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its grandparents.
Radiation can hurt us. We must know the truth.
1.Which of the following statements is true?
A.Nuclear radiation is just like common radio waves.
B.Nuclear radiation can cause cancer to human beings.
C.Nuclear radiation can be detected by human senses.
D.Nuclear radiation can be safe to human beings if its level is low.
2.How can nuclear radiation kill an animal?
A.By damaging its heart.
B.By killing a few cells.
C.By hitting any place in its body.
D.By killing many cells in important organs.
3.If a human being is hit by nuclear radiation, he may __________.
A.die of cancer after many years
B.die immediately
C.have a child who may be born weak
D.a(chǎn)ll of the above

Pupils remember more and behave better when 3D images areused in lessons,research suggests.They are quicker to learn andabsorb new concepts,and display higher levels of concentration.
Professor Anne Bamford,of the University of the Arts,London,studied the effectiveness of 3D content in 15 schools across seven countries,including the UK.Pupils in 3D classes can remember more than those in the 2D classes after four weeks,improving test scores by an average of 1 7 percent compared with eight percent for 2D lessons.They gave more detailed answer to the tasks and were more likely to think in 3D, using hand gestures and mime(模仿動(dòng)作) to answer the test questions successfully.
The teachers commented that the pupils in the 3D groups had deeper understanding,increased attention span, more motivation and higher engagement in the lessons.
Children are used to 3D with the rise of computer games that use the technology90 percent of those in the study had seen a 3D film.Schools would need 3Denabled projectors(投影儀),laptops with good picture capabilities,3D software and glasses for children to introduce animations(動(dòng)作) into classrooms.
But Danny Nicholson,an educationist,said the technology would be impractical to use inschools and could be costly.He said,“While I think the idea of 3D technology is very interesting,I worry that 3D is a bit of an expensive gimmick(小玩意兒).There are a few cases where a true3D image might help,but most of the time,good 2D models that can be moved would be just aseffective.”
In the US,one school district in Colorado is already in the process of having 1,000 3Dprojectors fixed in classrooms.And the University of Caledonia, which carries out scientific research into the Lake Tabon Basin, has used 3D presentations with Grade Six pupils.Those who watched the 3D presentations were more engrossed and reported a general increase in their interest in science compared with students who watched the 2D version.
1.What is the main idea of the first three paragraphs?
A.There are slight differences between 3D and 2D images.
B.Pupils perform better when 3D images are used in classes.
C.Schools have difficulties in making full use of 3D technology.
D.3D technology is always more effective than 2D technology.
2.Danny Nicholson holds the view that 3D ________.
A.is of no help in classes
B.has a bright future in classes
C.is more practical than 2D models
D.may not be affordable for schools
3.What can we learn from the last paragraph?
A.3D technology will replace 2D models in the future.
B.Many pupils are now more Interested In science than before.
C.Teachers will use the 3D technology through specific training.
D.3D will soon be put into use in one school district in Colorado.
4.The underlined word “engrossed” in the last paragraph means ________.
A.a(chǎn)bsorbed B.a(chǎn)nnoyed

科目:高中英語 來源:2015屆黑龍江紅興隆管理局第一高級中學(xué)高二下期中英語試卷(解析版) 題型:閱讀理解
Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that these are things you can eat. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense.
Although there are many different types of food, some animals spend their lives eating only one type. The giant panda(大熊貓)eats only one particular type of bamboo(竹子). Other animals eat only one type of food even when given the choice. A kind of white butterfly(蝴蝶)will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet(多樣化飲食). The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season.
Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat foods with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the health. Choosing the right food, therefore, has become an area of study in modern life.
1.We can infer from the text that humans and animals _________.
A. depend on one sense in choosing food
B. are not satisfied with their food
C. choose food in similar ways
D. eat entirely different food
2.Which of the following eats only one type of food?
A. The white butterfly. B. The small bird.
C. The bear. D. The fox.
3.Certain animals change their choice of food when ___________.
A. the season changes
B. the food color changes
C. they move to different places
D. they are attracted by different smells
4.We can learn from the last paragraph that __________.
A. food is chosen for a good reason
B. French and British food is good
C. some people have few choices of food
D. some people care little about healthy diet
