Space is a dangerous place, not only because of meteors (流星) but also because of rays from the sun and other stars. The atmosphere again acts as our protective blanket on earth. Light gets through, and this is necessary for plants to make the food that we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage.
Radiation is the greatest known danger to explorers in space, The unit of radiation is called “rem” Scientists have reason to think that a man can put up with far more radiation than 0.1rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage. A person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered until the birth of deformed children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and , during the outward and return journeys, the Apollo crew accumulated(积累) a large amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage done by radiation, but no really effective ones have been found so far.

Our planet is home to about seven billion people. Since the 1990s, population experts have predicted the number would grow to nine billion before it begins to slow down and possibly decrease.
But a new report predicts the world’s population is likely to increase to almost 11 billion by 2100. Based on the most modern statistical tools, the new report makes use of government records and considers expert predictions, including death rates, birthrates and international migration, or people moving across borders. The report says during the rest of this century, Africa's population will grow from about 3.5 billion to 5.1 billion over the next 85 years
John is director of the United Nations Population Division. He says that in the past, researchers thought population growth in Africa would be similar to that of other areas. They expected slower growth rates as birth control use became more widespread. But he says those ideas were wrong.
“The level of contraception use has continued to increase but slowly — more slowly than expected, and birthrate therefore has been falling less rapidly than expected, and the population therefore continues to grow somewhat more rapidly than we expected.The new findings are based on a joint research project of the United Nations and the University of Washington.
The researchers believe the population of Asia will reach five billion by 2050. That is up from the current 4.4 billion. And then begin to decline. The researchers also believe that North America, Europe, Latin America and the Caribbean area will have a total population of below one billion.
John says the pressure of feeding the rising population is likely to be less than that might be expected.
“The relatively good news is that the world has been winning the race between population growth and food production. If you look back historically over the last 50 years, certainly for the world as a whole and for many, most individual countries and regions, the increase in food production has outpaced the increase of population.‖”Which area will experience the largest increase in population at the end of the century?
| A．Asia. | B．Africa. | C．Europe. | D．North America. |
“Contraception use‖ in the fourth paragraph refers to ________.
| A．a method of expert predictions |
| B．a way of avoiding growth in population |
| C．a joint research into the rising population |
| D．a potential technology for food production |
Why is the pressure of feeding the rising population less than expected according to John?
| A．Expert predictions are not exactly like what the facts happen. |
| B．Birthrates have always been falling less rapidly than we expected. |
| C．The population grows less rapidly than population experts expected. |
| D．The increase in food production has outpaced the increase of population. |
What can be inferred from the passage?
| A．The world’s population will increase constantly. |
| B．The population of Asia will rise by 5 billion by 2050. |
| C．John is optimistic about feeding the rising population. |
| D．Population growth in Africa was much slower than expected. |
If you never read the classic F. Scott Fitzgerald’s novel The Great Gatsby, now is your chance to catch up — by watching the latest film adaptation. Because if there’s one sentence to sum up the film, it would be, as Fox News says in its review, “It’s just like the book”
Director Baz Luhrmann’s main challenge was “either to find a visual equivalent(相等物) for Fitzgerald’s elegant essay--the open secret of the book’s staying power-- or to bend the material to his own exotic(异国的) strengths,a Time magazine review says. He tries it both ways, with varying degrees of success.
Considered to be Fitzgerald's representative work, The Great Gatsby explores themes of idealism, resistance to change, social change, and excess, creating a portrait of the Jazz Age or the Roaring Twenties that has been described as a cautionary tale regarding the American Dream.
Nick, the narrator, moves to New York for the summer to visit his cousin Daisy. His next-door neighbor is Jay Gatsby (Leonardo DiCaprio), who rarely contacts with others and is rumored to be a hero of the Great War. Gatsby claims to have attended Oxford University, but the evidence is suspect. As Nick learns more about Gatsby, every detail about him seems questionable, except his love for the Daisy. Though Daisy is married, Gatsby still adores her as his ―golden girl.They first met when she was a young lady from a wealthy family and he was a working-class military officer. Daisy promised to wait for his return from the war. However, she married Tom, a classmate of Nick’s. Having obtained a great fortune, Gatsby sets out to win her back again.
”All of Fitzgerald’s original creation finds its way into this film, even going as far to include quite a bit of the original dialogue,US film critic Justin Taroli writes in his review. “The cast is beautiful as is the script, and the scenes are a visual feast.Taroli adds.
DiCaprio does a good and professional job as the socialite by re-creating Fitzgerald’s description of Gatsby’s charm. “He can look at someone for an instant and understand how, perfectly, he or she wants to be seen,David Denby, a film critic for The New Yorker, says in his review.
The use of music is almost reason enough to see the film. “Luhrmann is at his best mixing visual and musical styles together to create something wholly original, the Fox News review said.
For example, in one of the most outstanding scenes in the film, the first party scene, Nick walks quickly from one party guest to another party guest trying to explain all the gossip about Gatsby until he is finally introduced to the man himself, while the most stirring version of Rhapsody in Blue (composed by American musician George Gershwin in 1924) is played in the background.What did Baz Luhrmann do to make the film a success?
| A．He adapted the story in the novel as he wished. |
| B．He made the film more powerful than the book. |
| C．He mixed his style with the elegance of the essay. |
| D．He showed the elegance of the pictures in the film. |
What is Taroli’s attitude towards the film?
| A．Favorable. | B．Sceptical. |
| C．Amazed. | D．Unconcerned. |
What are the characteristics of Gatsby?
| A．Faithful and warm-hearted. |
| B．Charming and professional. |
| C．Selfish and stubborn. |
| D．Mysterious and devoted. |
Why does the author give the example of the first party scene in the last paragraph?
| A．Unfold the fact that Nick wants to know more about Gatsby. |
| B．Show the version of Rhapsody in Blue matches the film well. |
| C．Prove that the director is good at combining visual and music. |
| D．Convince us that the first scene is perfectly shot by the director. |
Brooke Martin’s golden retriever(金毛猎犬) Kayla hated being left alone or separated. She would howl, pace, and chew on things. Brooke learned that other people had the same problem with their pets. She wondered: ―What if you could talk to your dog if you were gone?
Working with her father in their garage, the 16-year-old came up with several ideas. Finally, she invented a device that allowed pet owners to video chat with their pets! She calls the device iCPooch. ―The dog doesn’t have to answer the call,explains Brooke. ―It comes up immediately on the screen on their end. It’s a two-way audio and video—you can see and hear each other.With a click of a button you can even send the dog a treat!
Her invention has earned her a spot competing against nine other finalists in a young scientist competition for middle-school students. These finalists, selected based on their short video presentations, are working with mentors over the summer before heading to the final competition in St. Paul, Minn.
After Martin’s video put her among the 10 finalists in the Discovery Education 3M Young Scientist Challenge, she was paired with Delony Langer-Anderson, a product development scientist in 3M’s consumer health care division. ―I just lead her down the product development path,Langer-Anderson told Live Science. This path includes guidance on how to test the potential product, which combines a video chat device that answers immediately on the dog’s end with a dog treat device the owner can remotely activate.
One thing I have thought about a lot is, what happens if while the device is on the floor, what if your dog knocks it over, or scratches the screen? Martin said. She and Langer-Anderson discussed this, and Martin is now testing materials at a local dog shelter by taping them to the dog house floors to see how well they withstand sharp teeth and claws.
The finalists create models they can test, with the guidance from a mentor. Their projects include a fuel cell that transforms cut grass into electricity and an app that rewards drivers for not texting or calling. Langer-Anderson tries to help the students work through the scientific method, testing their hypothesis, in a determined way, ―so the kids don’t get buried in data.she said.Which of the following would be the best title of the text?
| A．“iCPooch” wins in a young scientist competition. |
| B．A 16-year-old girl invents a device for dog hunger. |
| C．A man-made device lets people chat with their pets. |
| D．A kid-invented device calm dogs’ separation anxiety. |
“iCPooch”calms pet dogs by ________.
| A．allowing video chat |
| B．making dogs sleep |
| C．answering the call |
| D．giving them food |
What is the probable meaning of the underlined word“mentor”
| A．competitor | B．assistant | C．instructor | D．companion |
What do the inventions of the finalists have in common?
| A．They are all new inventions dealing with pets. |
| B．They are possible solutions to everyday problems. |
| C．They cope with the problems related to computers. |
| D．They are all accomplished through individual work. |

There was a little boy visiting his grandparents on their farm. He was given a slingshot（弹弓）to play with out in the woods. He practiced in the woods, but he could never hit the target. Getting a little discouraged, he headed back for dinner. As he was walking back he saw Grandma's pet duck.
Just out of impulse(冲动),he let the slingshot fly, hit the duck in the head and killed it. He was shocked! In a panic, he hid the dead duck in the wood, only to see his sister watching! Sally had seen it all, but she said nothing.
After lunch the next day Grandma said, "Sally, let's wash the dishes". But Sally said, "Grandma, Johnny told me he wanted to help in the kitchen. "Then she whispered to him, "Remember the duck?" So Johnny did the dishes. Every time Grandma asked Sally to do some housework, she will repeat the same story. After several days of Johnny doing both his work and Sally's, he finally couldn't stand it any longer. He came to Grandma and confessed that he had killed the duck.
Grandma gave him a hug and said, "Sweetheart, I know. You see, I was standing at the window and I saw the whole thing, but because I love you, I forgave you. I was just wondering how long you would let Sally make a slave of you. "
