All students of geography should to interpret a weather map accurately. Weather maps contain an enormous amount of information about weather conditions existing at the time of observation over a large geographical area. They reveal in a few minutes what otherwise would take hours to describe. The United States Weather Bureau issues information about approaching storms, floods, frosts, droughts and all climate conditions in general. Twice a month it issues a 30-day “outlook” which is a rough guide to weather conditions likely to occur over broad areas of the United States. These outlooks are based on an analysis of the upper air levels.
With the use of electronic instruments and satellites, enormous gains have taken place recently in identifying and tracking storms over regions which have but few meteorological stations(气象站).Experiments are also in progress for weather modification studies, although few successful results such as artificial rainmaking have been achieved so far.
小题1: Which is not mentioned in this passage in the following about one characteristic of weather?
| A．Fronts. | B．Temperature change. | C．Wind speed. | D．Frost. |
_______.
| A．it is modern and sophisticated |
| B．it used electronic instruments |
| C．it enables man to alter the weather |
| D．it gives the scientists information not obtained readily otherwise |
| A．explain | B．present | C．modify | D．illustrate |
答案
小题1:B
小题2:D
小题3:A
解析
小题1:从第一、二段可以发现fronts, wind speed, frost都被提到。
小题2:从最后一段可知。
小题3:从下一句话可知interpret是“解释”的意思。

Proper training allows the animals to receive the care they need. It was very difficult to get untrained animals, especially the larger ones, to stay still when they needed medical attention. Now they can be trained, on command, to remain still and even to allow blood samples to be taken and shots administered. All this is accomplished through positive reinforcement, without the use of any force. Affection training, as this process is called, has been used with great success on a wide variety of zoo animals. Animal behavior experts have taught zoo keepers to train bears, tigers, monkeys, and many other species to behave in a way that provides for better animal-keeper interaction. This training also keeps the animals from becoming bored and inactive.
Although some people proclaim(谴责) that this training is inhumance and cruel to animals, results have shown that captive(猎获的)animals who previously were not doing well flourish under the new training procedures.
小题1:The word “listless” means _______.
| A．countless | B．obedient |
| C．inactive | D．mysterious |
| A．It is safe to pet any animal. |
| B．Many animals respond favorably to rewards and affection. |
| C．Animals in the wild can be trained. |
| D．Animals should not be kept in zoos. |
| A．persuade people not to feed animals in the zoo |
| B．show how easy it is to train animals |
| C．explain method of training animals through rewards |
| D．criticize zoo keepers |
| A．Zoo keepers had problems in getting animals to leave their cages. |
| B．Training is cruel to animals. |
| C．Animals obey commands if they are trained to do so. |
| D．Many animals can be trained, on commands, to remain still. |
Tina and Mark noticed similar changes in their 14-year-old daughter. “She used to cuddle up(蜷伏) with me on the soft and talk,” said Mark.“Now we joke that she does this only when she wants something. Sometimes she wants to be treated like a young lady. The problem is figuring out which time is which.”
Before age 11, children like to tell their parents what"s on their minds.“In fact, parents are first on the list,” said Michael Riera, author of Uncommon Sense for Parents with Teenagers.“This completely changes during the teen years.” Riera explained.“They talk to their friends first, then maybe their teachers, and their parents last.”
Parents who know what"s going on in their teenagers" lives are in the best position to help them. To break down the wall of silence, parents should create chances to understand what their children want to say, and try to find ways to talk and write to them. And they must give their children a mental break, for children also need freedom, though young.Another thing parents should remember is that to be friend, not a manager, with their children is a better way to know them.
小题1:“The door to his room is always shut” suggests that the son_______.
| A．is always busy with his studies |
| B．doesn"t want to be disturbed |
| C．keeps himself away from his parents |
| D．begins to dislike his parents |
| A．their daughter isn"t as lovely as before |
| B．they can"t read their daughter"s mind exactly |
| C．they don"t know what to say to their daughter |
| D．their daughter talks with them only when she needs help |
| A．Teenagers talk a lot with their friends. |
| B．Teenagers do not want to understand their parents. |
| C．Teenagers do not talk much with their parents. |
| D．Teenagers talk little about their own lives. |
| A．Parents are unhappy with their growing children. |
| B．Parents have suitable ways to talk with their teenagers. |
| C．Parents should be patient with their silent teenagers. |
| D．Parents should try to understand their teenagers. |
Some will put their hands in ice water just before competing and nearly all will be wearing fabrics(织物) designed with hot weather in mind.
“Normally we warm up before exercise,”said Gordon Sleivert, director of sports science and medicine at the Canadian Sport Center in Victoria, British Columbia.“But in this case we"re taking the warm out of warm up. It"s like pre-cooling.”
Experts are predicting(预测) the average high this August in Athens will be 90 degrees Fahrenheit, with temperatures often reaching above 100(the average temperature in Sydney for the 2000 summer games was 64).
Although some events, such as the marathon, will start early(1 a.m.) to avoid hot weather, other competitors will be pushing their limits during high temperatures. Drinking lots of water will help athletes keep cool, but humidity(湿度) remains a problem. The body"s ability to cool down is weakened by damp air since sweat drips off the skin rather than evaporates(蒸发),resulting in dehydration(脱水) without the cooling.
“Getting hot is a real problem because when our brains heats up, the brain waves are more like when you"re really sleepy. Everything feels harder,” said Sleivert.
小题1: The passage mainly tells us that _______.
| A．why it is very hot in Athens |
| B．the hot weather is a big problem for Olympic athletes |
| C．how important science is to every athlete |
| D．the Olympics will be put off because of the hot weather |
| A．Olympic athletes will put off their competition time |
| B．some events in the Olympics will have to be put forward |
| C．competitors can"t reach their limits in the hot weather |
| D．competitors will have to try their best to compete under any condition |
| A．dehydration |
| B．being sleepy |
| C．that the blood in the body can become less and less |
| D．that the body"s ability to cool down is weakened |
It is now clear that this is not so. Babies will learn to behave in ways that produce results in the world with no reward except success in sight.
Papousek began his studies by using milk in the normal way to “reward” the babies and to teach them to carry out some simple movements, such as turning the head to one side or the other.Then he noticed that a baby who had had enough to drink would refuse the milk but would still go on making the learned response(回答) with clear signs of pleasure. So he began to study the children"s responses in situations where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement “turned on” some lights—and indeed that they were able to learn some more turns to bring about(产生) this result,for example,two left or two right,or even to make as many as three turns to one side.
Papousek"s light experiment was placed directly in front of the babies and he made the interesting observation that sometimes they would not turn back to watch the light closely although they would “smile and speak” when the light was on.Papousek concluded that it was not the sight of the lights which pleased them.It was the success they were achieving in solving the problem,in mastering the skill,and then there is a basic human nature to make sense of the world and bring it under control.
小题1:According to the writer,babies learn to do things which _______.
| A．will satisfy their surprise | B．will meet their physical needs |
| C．are directly connected to pleasure | D．will bring them a feeling of success |
| A．would make learned responses when it saw the milk |
| B．would continue the simple movements without being given milk |
| C．would turn its head to right or left when it had enough to drink |
| D．would carry out learned movements when it had enough to drink |
| A．be praised | B．please their parents |
| C．be rewarded with milk | D．have the lights turned on |
| A．they succeeded in “turning on” the lights |
| B．the sight of lights was interesting |
| C．they need not turn back to watch the lights |
| D．the lights were directly connected to some basic “drives” |
One application, called Lecture Translation, can easily translate a speech from one language into another. Current translation technologies typically limit speakers to certain topics or a limited vocabulary. Users also have to be trained how to use the programme.
Another prototype(雏形机) can send translations of a speech to different listeners depending on what language they speak.“It is like having a simultaneous translator right next to you but without disturbing the person next to you,” Waibel said.
Prefer to read? So-called Translation Glasses transcribe(转录) the translations on a tiny liquid-crystal(液晶) display(LCD) screen.
Then there"s the Muscle Translator. Electrodes capture the electrical signals from facial muscle movements made naturally when a person is mouthing words. The signals are then translated into speech. The electrodes could be replaced with wireless chips implanted in a person"s face, according to researchers.
During a demonstration held last Thursday in CMU"s Pittsburgh campus, a Chinese student named Stan Jou had 11 tiny electrodes attached to the muscles of his cheeks, neck and throat. Then he mouthed—without speaking aloud—a few words in Mandarin(普通话) to the audience. A few seconds later, the phrase was displayed on a computer screen and spoken out by the computer in English and Spanish: “Let me introduce our new prototype.”
This particular gadget(器械),when fully developed, might allow anyone to speak in any number of languages or, as Waibel put it, “to switch your mouth to a foreign language”. “The idea behind the university"s prototypes is to create ‘good enough’ bridges for cross-cultural exchanges that are becoming more common in the world,” Waibel said.
With spontaneous(自发的) translators, foreign drivers in Germany could listen to traffic warnings on the radio, tourists in China could read all the signs and talk with local people, and leaders of different countries could have secret talks without any interpreters there.
小题1:Which of the following statements is not TRUE?
| A．A lecture translation can translate what you said into other languages easily. |
| B．There is no Muscle Translator in the world now. |
| C．Muscle Translators can translate what you think into speech if you just move your mouth. |
| D．The spontaneous translators will help us a lot. |
| A．Lecture Translation. |
| B．Muscle Translator. |
| C．Multiple Translator. |
| D．Translation Prototype. |
| A．To make cultural exchanges between different countries easier. |
| B．To help students learn foreign languages more easily. |
| C．To make people live in foreign countries more comfortably. |
| D．To help people learn more foreign languages in the future. |
| A．A newspaper. | B．A magazine on science. |
| C．A fairy tale. | D．A scientific fantasy book. |
