2014高考英语阅读理解精英定时训练题（13）及答案【甘肃省嘉峪关市一中2013模拟】 deven plants can run a fever, especially when theyre under attack by insects or disease. but unlike human, plants can have their temperature taken from 3,000 feet awaystraight up. a decade ago, adopting the infrared(红外线)scanning technology developed for military purposes and other satellites, physicist stephen paley came up with a quick way to take the temperature of crops to determine which ones are under stress. the goal was to let farmers precisely target pesticide(杀虫剂)spraying rather than rain poison on a whole field, which invariably includes plants that dont have pest problems.even better, paleys remote scanning services company could detect crop problems before they became visible to the eye. mounted on a plane flown at 3,000 feet at night, an infrared scanner measured the heat emitted by crops. the data were transformed into a colourcoded map showing where plants were running “fevers”. farmers could then spotspray, using 50 to 70 percent less pesticide than they otherwise would.the bad news is that paleys company closed down in 1984, after only three years. farmers resisted the new technology and longterm backers were hard to find. but with the renewed concern about pesticides on produce, and refinements in infrared scanning, paley hopes to get back into operation. agriculture experts have no doubt the technology works. “this technique can be used on 75 percent of agricultural land in the united states, ” says george oerther of texas a & m. ray jackson, who recently retired from the department of agriculture, thinks remote infrared crop scanning could be adopted by the end of the decade. but only if paley finds the financial backing which he failed to obtain 10 years ago.53plants will send out an increased amount of heat when they are_.afacing an infrared scannerbsprayed with pesticidescin poor physical conditiondexposed to excessive sun rays54in order to apply pesticide spraying precisely, we can use infrared scanning to_.aestimate the damage to the cropsbdraw a colourcoded mapcmeasure the size of the affected areadlocate the problem area55farmers can save a considerable amount of pesticide by_.aresorting to spotsprayingbtransforming poisoned raincconsulting infrared scanning expertsddetecting crop problems at an early stage56the application of infrared scanning technology to agriculture

the inside that counts, then a lot of thin people might be in trouble.some doctors now think that the internal fat surrounding important organs like the heart or liver could be as dangerous as the external fat which can be noticed more easily.“being thin doesnt surely mean you are not fat,” said dr jimmy bell at imperial college. since 1994, bell and his team have scanned nearly 800 people with mri machines to create “fat maps” showing where people store fat.according to the result, people who keep their weight through diet rather than exercise are likely to have major deposits of internal fat, even if they are slim.even people with normal body mass index scores can have surprising levels of fat deposits inside. of the women, as many as 45 percent of those with normal bmi scores (20 to 25) actually had too high levels of internal fat. among men, the percentage was nearly 60 percent.according to bell, people who are fat on the inside are actually on the edge of being fat. they eat too many fatty and sugary foods, but they are not eating enough to be fat. scientists believe we naturally store fat around the belly first, but at some point, the body may start storing it elsewhere.doctors are unsure about the exact dangers of internal fat, but some think it has something to do with heart disease and diabetes. they want to prove that internal fat damages the bodys communication systems.the good news is that internal fat can be easily burned off through exercise or even by improving your diet. “if you want to be healthy, there is no short cut. exercise has to be an important part of your lifestyle,” bell said.11. what is this piece of news mainly about?a. thin people may be fat inside. b. internal fat is of no importance.c. internal fat leads to many diseases. d. thin people also have troubles.12.doctors have found _.a. the exact dangers of internal fatb. internal fat is the cause of heart disease and diabetesc. being slim is not dangerous at alld. being slim doesnt mean you are not fat inside13.according to the passage, which of the following is wrong?a. exercise can help to reduce the internal fat.b. people can get rid of internal fat by improving diet.c. men are more likely to have too much internal fat.d. people with heart disease all have internal fat.14.from the last paragraph, we can find that _.a. whether internal fat can lead to disease has been provedb. exercise plays in important role in peoples life for keeping healthyc. thin people usually have internal fat even if they are slimd. it is easier to burn off internal fat than external fat15.the underlined part in the last paragraph means _.a. a long roadb. an easy way c. a clear differenced. a short distance参考答案 1115 addbb the rising costs of health care have become a problem for many countries in the world. to deal with this problem, it is recommended that a big part of the governments health budget be used for health education and disease prevention instead of treatment. actually, many kinds of diseases are preventable in many ways and preventing a disease is usually much cheaper than treating it. for example, people could avoid catching a cold if they dressed warmly when the weather starts getting cold. but many people get sick because they fail to do so, and have to spend money seeing a doctor.daily habits like eating more healthy food would have kept millions of families from becoming bankrupt if the patients had taken measures for early prevention. for instance, keeping a balanced diet, such as not consuming too much animal fat and insuring a steady intake of vegetables and fruits, seems to be quite important.one very effective and costless way of prevention is regular exercise, which is necessary for a healthy mind and body. regular exercise, such as running, walking, and playing sports is a good way to make people feel better or reduce stress.in addition, health education plays a key role in improving peoples health. by giving people more information about health, countries could help people understand the importance of disease prevention and ways to achieve it. for example, knowing ones family medical history is an effective way to help keep healthy. information about health problems among close relatives will make them aware of what they should do to prevent certain diseases through lifestyle changes, which will work before it is too late.however, stressing disease prevention does not mean medical treatment is unimportant. after all, prevention and treatment are just two different means toward the same effect. in conclusion, we could save money on health care and treat patients more successfully if our country spends more money on health prevention and education.6which of the following shows the structure of the passage?cp (central point)p (point)sp (sub-point次要点)c (conclusion)7which of the following can replace the underlined word “bankrupt?astronger than ever before bmore successful than

elephants can! they can use their sense of vision and smell to tell the difference between people who pose a threat and those who do notin kenya, researchers found that elephants react differently to clothing worn by men of the maasai and kamba ethnic groupsyoung maasai men spear animals and thus pose a threat to elephants; kamba men are mainly farmers and are not a danger to elephantsin an experiment conducted by animal scientists, elephants were first presented with clean clothing or clothing that had been worn for five days by either a maasai or a kamba manwhen the elephants detected the smell of clothing worn by a maasai man, they moved away from the smell faster and took longer to relax than when they detected the smells of either clothing worn by kamba men or clothing that had not been worn at allgarment color also plays a role, though in a different wayin the same study, when the elephants saw red clothing not worn before, they reacted angrily, as red is typically worn by maasai menrather than running away as they did with the smell, the elephants acted aggressively toward the red clothingthe researchers believe that the elephants emotional reactions are due to their different interpretations of the smells and the sightssmelling a potential danger means that a threat is nearby and the best thing to do is run away and hideseeing a potenti
