1、專題限時(shí)訓(xùn)練(二十六)科普知識(shí)型閱讀理解(二)(限時(shí)：25分鐘)(一)Studying volcanoes is a demanding profession. Hazel Rymer frequently has to struggle through rainforests, climb to the top of mountains, then climb 200 metres into the crater of active volcanoes. But the 38yearold volcanologist does her best to make it sound less a
2、larming than it is. “Driving to work is more risky，” she insists. “And the deepest I go into the crater of a volcano is about 300 metres，” she adds, trying to make it all sound as ordinary as taking the dog for a walk. Hazel has been studying volcanoes for a long time, so its not surprising that she
3、 is used to the danger. Her interest in volcanoes began at school. A teacher gave her a book about Pompeii. “I remember reading about the eruption of Vesuvius and the destruction of the city，” she explains. “The thought of all those people just frozen in time had quite an effect on me and I am still
4、 excited by their dangerous beauty today.” Nowadays, volcanoes are getting more and more unpredictable. There have been many changes in sea level caused by global warming and melting ice caps. These have resulted in some dormant volcanoes erupting, so studying them is more dangerous than ever before
5、. Hazel says that although she doesnt take any unnecessary risk, she has had some frightening moments. Her worst experience was on the slopes of Mount Etna in Sicily, when she was slowly surrounded by lava. “I had a choice of walking ten hours to get around the lava flow or just walking across it，”
6、she explains. She chose to pick a path across the cooler rocks in the lava stream. “I guess it was five metres. The flow was 1，000， so if you hesitated your boots would begin to melt. It was scary, but it really was a practical decisionthere wasnt time to do anything else.” And what about the future
7、? “I havent been to the volcanoes in Indonesia yet. And I would love to spend some time working in the Antarctic，” she says. “I would also like to know why quiet lava flows erupt from some volcanoes and why other volcanoes go bang.” In other words, Hazel Rymer wont be exchanging her volcanoes for th
8、e relative safety of Driving to work just yet. 1. Hazels claim that “Driving to work is more risky” than exploring volcanoes shows that _. A. people have exaggerated the dangers of volcanoes in the past B. Hazel does not really understand the dangerous situations she puts herself in C. there are man
9、y bad drivers in the place where Hazel lives D. Hazel is being modest and understating the dangers she faces 2. When did Hazel first become interested in volcanoes? A. When she was visiting Italy. B. When she was at school. C. When she was twenty. D. When she saw Vesuvius. 3. The underlined word “Th
10、ese” (Paragraph 3) refers to _. A. melting icecaps B. volcanic eruptions C. changes in sea level D. higher temperatures 4. When Hazel was on Mount Etna she had to _. A. take a dangerous route B. take an unnecessary risk C. leave her boots behind D. walk for ten hours around the mountain 5In the futu
11、re, Hazel wants to _. A. revisit volcanoes she knows B. go on holiday to the Antarctic C. find a less dangerous job D. discover new things about volcanoes(二)Europes deadly outbreak of a rare form of Ecoli(大腸桿菌) bacteria has brought new attention to food safety issues. Ecoli bacteria naturally live i
12、n the intestines(腸) of humans and many animals. Most kinds of Ecoli are harmless but some can make people sick.One of the problems when people get sick from food is that the simplest question is often difficult or even impossible to answer. Just what did the people eat that made them sick? Of course
13、, one way to avoid such problems is to keep dangerous organisms out of the food supply. This_is_easier_said_than_done,_but scientists keep looking for new ways.Scientists in the United States have developed an experimental system that uses a hightech optical(光學(xué)的)scanner. The inspection system is fix
14、ed in the packing houses where produce is sorted for market. The system is designed to identify the produce polluted by soil or animal waste. The new scanner can also show damage and imperfections that might make the produce unappealing to shoppers.Scientists designed the system at a Department of A
15、griculture research centre in Beltsville, Maryland. Moon Kim of the Agricultural Research Service led the team.MOON KIM: “We were requested, we were asked, to develop a method to test the polluted produce. So we started with the apple as the model sample.”The scanner uses a highspeed camera placed o
16、ver the conveyer belt that moves the produce along. As the apples move along the belt, the scanner captures images of each piece of fruit. A spectrograph device can use the light to check an apple to show evidence of damage. Moon Kim says the team hopes the system will be available before long.MOON
17、KIM: “We are targeting for development in commercial plants for the next several years.”The scanner can direct a sorting machine to separate the bad apples from the good ones. The system is currently able to show the surface of only half the apple as it speeds by. The inventors hope to improve the p
18、rocess so it can show the whole surface.1. The passage mainly talks about _A. the danger of Ecoli bacteria to healthB. the way to avoid getting sick from foodC. a system to test the polluted produceD. the new attention to food safety issues2According to the passage, we know the new scanner _A. has a
19、lready used in the supermarketB. is perfect to find out the polluted appleC. is still in test and need to improveD. can also damage the bacteria in the food3What can we learn from the passage?A. Most of the Ecoli is dangerous to the peoples health.B. The damage in the fruit might cause it difficult
20、to sell out.C. Now the system can take the pictures of each piece of fruit.D. The scanner is put on a moving belt while testing the produce.4. By saying “This is easier said than done” in Paragraph 2, the writer wants to _A. show the difficulty in finding the bad bacteria from the food supplyB. show
21、 the scientists hardship in finding a new way to heal the diseaseC. express his/her anger to the businessmen from selling the polluted foodD. express his/her worry about the dangerous issue in todays food safety5This passage can be classified as _A. an advertisement B. a book reviewC. a feature stor
22、y D. a news report(三)Clothes can make phone calls, play music, dial your pals number, keep you warm during cold weather and operate your computer? This is not a fantasy. A British company, called Electrotextiles, has created a wide range of clothes that have minds of their own! Scientists, working f
23、or the company, have invented a kind of fabric that can be blended(混合) with flexible electronic materials to create intelligent clothing. The result are electronic garments.If you think the wearer has to be wired to different devices, think again. These designer clothes are wirefree, soft to touch a
24、nd washable! Like any electronic device, these hightech clothes have to be powered. Currently, a tiny ninevolt battery serves the purpose. But the researchers hope that in the near future the clothes will generate electricity by using body heat. “These clothes are 100 percent shock proof，” they say.
25、The Electrotextiles team has also created the worlds first cloth keyboard. This keyboard can be sewn into your trousers or skirt. To use this device, you will have to sit down and tap on your lap! These “l(fā)aptap” gadgets(小器具) are all set to take over laptop computers!Another useful garment is the shi

Other popular electronic wear include the denim(牛仔布) jacket with flexible earphones sewn into the hood(風(fēng)帽) and the electronic ski jacket with a builtin heater. The ski jacket is also programmed to s
27、end signals to a satellite. This technology is known as global positioning system and can be used to track lost skiers and wandering kids.Having completed the cloth keyboard, scientists have already started to work on a new projecta necktie that can be used as a computer mouse. What is the next? Do
