Joker found one of the biggest diamonds in the world right in his own back yard.
题型：不详难度：来源：
Joker found one of the biggest diamonds in the world right in his own back yard. He sold the stone to a diamond dealer for over three hundred thousand dollars. In New York, the diamond was resold---this time for almost eight hundred thousand dollars. The true value of a diamond is never known until it has been cut. Once cut successfully, its value can increase a thousand times. It"s easy to understand why the owner of Joker"s diamond went to the best diamond cutter he knew, Kaplan. The cutter studied the diamond for twelve whole months.
When he felt he was ready to start work, he discovered a flaw (瑕疵) . He had to begin his calculations all over again, or he might have made the stone useless. Six months passed, and Kaplan finally said to the owner, “I am ready to start my work. There will be one excellent diamond that will be comparable one excellent diamond of first-class quality (质量) " Kaplan waited a few more days until he felt he was in the best physical and mental (精神的) condition(条件) possible. He picked up his tools (工具) and held his breath as he made the diamond exactly as he promised.

Welcome to your future life!
You get up in the morning and look into the mirror. Your face is firm and young-looking. In 2035, medical technology is better than ever. Many people your age could live to be 150, so at 40, you’re not old at all. And your parents just had an anti-aging(抗衰老的) treatment. Now, all three of you look the same age !
You say to your shirt, “Turn red.” It changes from blue to red. In 2035, “smart clothes” contain particles(粒子) much smaller than the cells in your body. The particles can be programmed to change your clothes’ color or pattern.
You walk into the kitchen. You pick up the milk, but a voice says, “You shouldn’t drink that!” Your fridge has read the chip (芯片) that contains information about the milk , and it knows the milk is old . In 2035, every article of food in the grocery store has such a chip.
It’s time to go to work. In 2035, cars drive themselves. Just tell your “smart car” where to go. On the way, you can call a friend using your jacket sleeve(袖子). Such “smart technology” is all around you.
So will all these things come true? “For new technology to succeed,” says scientist Andrew Zolli , “it has to be so much better that it replaces what we have already.” The Internet is one example --what will be the next?
小题1:We can learn from the text that in the future__________.| A．people will never get old | | B．everyone will look the same | | C．red will be the most popular color | | D．clothes will be able to change their pattern |
小题2:What can be inferred from Paragraph 4?| A．Milk will be harmful to health. | | B．More drinks will be available for sale. | | C．Food in the grocery store will carry electronic information. | | D．Milk in the grocery store will stay fresh much longer. |
小题3:What is the text mainly about?| A．Food and clothing in 2035. | | B．Future technology in everyday life. | | C．Medical treatments of the future. | | D．The reason for the success of new technology. |

I spent two months with an American family last year when I studied in America．It is said that “The best house is in the U.S.A．， the best wife is in Japan and the best food is in China．”So I took 36 and pleasure to 37 “the best food” for my American family．Each day，regardless of my poor skill of cooking，I performed my play in 38 way：changing the dishes’colour，the meat’s type or the soup’s style．Thus，my American friends could discover the 39 of eating Chinese food． Because of my“ 40 ” job，I was often rewarded by their 41 of appreciation , such as “very tasty”，“excellent”etc．But the joke was here： yesterday， I cooked Sichuan－style 42 for dinner．I was 43 at my achievement．When all the family members arrived at the table，they first looked 44 at the fish，then looked at me． “Why do all the fish have their 45 ？” they asked，“It’s horrible！” Horrible or beautiful？ I don’t know． But I 46 know that fish heads are delicious. The 47 is the best part of fish； in 48 only the respectable guest can have the special 49 of enjoying it． Another 50 thing is：the American friends often said to me“ 51 ”as they 52 fruits or other things． According to Chinese tradition，I would simply smile in answer to their kindness 53 actually helping myself to any of the food. 54 ，I said “help yourself” to them whenever I brought home fruits．Dear me，no matter how much or how often I brought home food， as long as it was nice to their taste，they 55 hesitated to use their hands to “help themselves” until all was finished．

Psychologists(心理学家) have known that what"s going on inside our head affects our senses. For example, poorer children think coins are larger than they are, and hungry people think pictures of food are brighter. Professor Remi Radel wanted to investigate(look into) how this happens -- whether it"s right away, as the brain receives signals from the eyes, or a little later, as the brain"s higher-level thinking processes get involved.
Radel chose 42 students and each student was told to arrive at the lab at noon after three or four hours of not eating on the day of the test. Then they were told there was a delay. Some were told to come back in 10 minutes; others were given an hour to get lunch. So half the students were hungry when they did the experiment and the other half had just eaten.
For the experiment, the participant looked at a computer screen. One by one, 80 words flashed on the screen. A quarter of the words were food-related. After each word, the person was asked how bright the word was and asked to choose which of two words they"d seen -- a food-related word like gateau (cake) or a neutral (中性的) word like bateau (boat).
Hungry people saw the food-related words as brighter and were better at identifying food-related words. Because the word appeared too quickly for them to be reliably seen, this means that the difference is in perception (直觉), Radel says—it"s not because of some kind of processing happening in the brain after you"ve already figured out what you"re looking at.
"This is something great to me, that humans can really realize what they need or what they hope for, to know that our brain can really arrange for our motives and needs," Radel says. "There is something inside us that selects information in the world to make life easier.”
小题1:The purpose of Radel"s research is to let us know ____.| A．how our thinking has effect on our senses happens | | B．what it is the good time for students to have lunch | | C．whether poorer children think coins are larger than they are | | D．whether hungry people think pictures of food are brighter |
小题2:In the experiment 20 words that flashed on the screen had something to do with “____”.| A．boat | B．food | C．mind | D．weather |
小题3:Which of the following is true about the experiment?| A．The students should stare at the words in the book. | | B．Each word appeared slowly in order that the participant could read it exactly. | | C．After each word flashed on the screen, the person was asked to finish two tasks. | | D．On the day of the test, all the students were very hungry because of the delay of their lunch. |
小题4:What does the new study find?| A．Actually our brain can arrange for our motives and needs. | | B．In the experiment the brain was totally controlled by the senses. | | C．People who had just eaten saw all the words more clearly than hungry people. | | D．The participants saw the words look different long after the brain dealt with the information. |

Everybody hates rats. But in the earthquake capitals of the world—Japan, Los Angeles, Turkey—rats will soon be man’s new best friends.
What happens after an earthquake? We sent in rescue dogs. Why? Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can’t get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.
How does it work? First, the rat is trained to smell people. When this happens, the rat’s brain gives a signal (信号). This is sent to a small radio on its back, and then the rescuers follow the radio signals. When the rat’s brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.
Although there are already robots which can do this job, rats are better. Christian Linster at Cornell University,New York, says, “‘Robots ’noses don’t work well when there are other smells around. Rats are good at that.” Rats can also see in the dark. They are cheaper and quicker to train than dogs, and unlike robots, they don’t need electricity(电)!
The “rat project” is not finished, but Julie Ryan of International Rescue Corps in Scotland says, “It would be fantastic. A rat could get into spaces we couldn’t get to and a rat would get out of it if it wasn’t safe.” Perhaps for the first time in history, people will be happy to see a rat in a building (but only after an earthquake, of course).
小题1:In the world earthquake capitals, rats will become man’s best friends because they can .| A．take the place of man’s rescue jobs | | B．find the position of people alive who are trapped in buildings | | C．serve as food for people alive who are trapped in buildings. | | D．get into small spaces |
小题2:In doing rescue jobs, .| A．rats smell better than dogs | | B．dogs don’t need to be trained to smell people | | C．robots’ sense of smell can be affected by other smells around | | D．rats can see in the dark and smaller than robots |
小题3:Rats have all the following advantages EXCEPT that .| A．they are more fantastic than other animals | | B．they are less expensive to train than dogs | | C．they don’t need electricity | | D．they are small and can get into small places |
小题4:After reading the passage we can know .| A．at present rats have taken the place of dogs in searching for people | | B．the “rat project” has been completed | | C．people are now happy to see a rat in a building | | D．now people still use dogs and robots in performing rescues |

Honey from the African forest is not only a kind of natural sugar, it is also delicious. Most people and many animals like eating it. However, the only way for them to get that honey is to find a wild bees" nest and take the honey from it. Often, these nests are high up in trees, and it is difficult to find them. In parts of Africa, though, people and animals looking for honey have a strange and unexpected helper - a little bird called a honey guide.
The honey guide does not actually like honey, but it does like the wax in the beehives (蜂房). The little bird cannot reach this wax, which is deep inside the bees" nest. So, when it finds a suitable nest, it looks for someone to help it. The honey guide gives a loud cry that attracts the attention of both passing animals and people. Once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest. When they finally arrive at the nest, the follower reaches in to get at the delicious honey as the bird patiently waits and watches. Some of the honey and the wax always falls to the ground, and this is when the honey guide takes its share.
Scientists do not know why the honey guide likes eating the wax, but it is very determined(坚定的) in its efforts to get it. The birds seem to be able to smell wax from a long distance away. They will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.
小题1:Why is it difficult to find a wild bees" nest?| A．It"s small in size. | B．It"s hidden in trees. | | C．It"s covered with wax. | D．It"s hard to recognize. |
小题2:What do the words "the follower" in Paragraph 2 refer to?| A．A bee. | B．A bird. | C．A honey seeker. | D．A beekeeper. |
小题3:The honey guide is special in the way .| A．it gets its food | B．it goes to church | | C．it sings in the forest | D．it reaches into bees" nests |
小题4:What can be the best title for the text?| A．Wild Bees | B．Wax and Honey | | C．Beekeeping in Africa | D．Honey-Lover"s Helper |
