题目内容
【题目】Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources, as well as one of the oldest. Evidence shows that windmills began to be used in the ancient Iran back in the seventh century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.
For many centuries, people used windmills to grind(磨碎)wheat into flour or____water from deep underground. When electricity was discovered in the late 1800s, people living in remote areas began to use them to produce electricity. This allowed them to have electric lights and radios. However, by the 1940s when electricity was available to people in almost all areas of the United States, windmills were rarely used.
During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher costs. Today, there is a global movement to supply more and more of our electricity through the use of wind.
【1】From the text we know that windmills _______.
A. were invented by European armies
B. have a history of more than 2,800 years
C. have rarely been used since electricity was discovered
D. used to supply power to radio in remote area
【2】The underlined word in Paragraph 2 probably means________.
A. making something cleaner
B. making something flow freely
C. making something flow in a particular direction
D. making something into small parts
【3】One of the reasons wind was discovered in the 1970s is that_______.
A. it is one of the oldest power sources
B. wind power is cleaner
C. it was cheaper to create energy from wind
D. coal and gas failed to meet the needs
【4】What would the author probably discuss in the paragraph that follows?
A. The global trend towards producing power from wind.
B. The design of wind power plants.
C. The worldwide movement to save energy.
D. The advantages of wind power.
【答案】
【1】D
【2】C
【3】B
【4】A
【解析】试题分析:本文分析了人类使用风能的历史,从使用风车到风能慢慢被遗忘。到近期人民又重新使用风能,以及现在使用风能的新的趋势。
【1】D细节题。根据文章第二段2,3行When electricity was discovered in the late 1800s, people living in remote areas began to use them to produce electricity. This allowed them to have electric lights and radios.可知偏远地区的人使用风力发电来使用收音机。
【2】C根据For many centuries, people used windmills to grind(磨碎)wheat into flour orpump water from deep underground.可知许多世纪以来,人们用风车来磨(磨碎)小麦磨成面粉或从深深的地下泵水。故pump是指在某个特定的方向上使某事物流动,故选C。
【3】B推理题。根据文章最后一段During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher cost.可知煤炭和石油会带来污染,所以人民开始使用风力发电的原因是因为风力是清洁能源。
【4】A推理题。根据文章最后一段可知人民开始使用风力来发电。那么接下来就应该讨论就应该是全球的趋势。
【题目】根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。In recent years, research on the human brain has been attracting more and more scientists. 【1】 If we compare a human brain to a hard disc(硬盘), what the scientists are doing is to make better use of the hard disc.Experiments have started on animals. In 1999, a transplant(移植) experiment was done at the Defense and Military Physiology Research Institute in the U.S. and turned a bear into a dolphin(海豚). 【2】They were made of the memory area in the dolphin’s brain containing information about swimming. They obtained a series of useful information, which was saved into a button-sized chip(芯片). Later the information was transplanted into the action memory area in the bear’s brain. 【3】 It proved to be a highly successful experiment and a bear was turned into a dolphin.Not long ago, another memory transplant was performed at the Motor Nerve Research Institute of the University of California. The experiment had an entire transplant of the memory area. 【4】 The transplant was performed froma dog named “Genius” to a dog named “Idiot”. “Genius” could understand and follow up to 100 gestures and orders made by its master. It was a real genius in memorizing. However, “Idiot” had no contact with people at all since its birth. It became an animal with nothing in its brain, without any memory.【5】When the two dogs woke up, “Idiot” had grasped all the abilities “Genius” had; it was good at memorizing and sensible. It could follow every gesture and any command given by itsmaster. But “Genius” gave no response to its master, and in fact did not recognize him at all.
A. The experiment was a complete success. |
B. Then it was released(释放) by means of electric power. |
C. One of the latest research topics is how to change the human brain or combine it with the computer. |
D. Different images have different meanings in the memory area. |
E. It included actions, moods, logic, words, images, etc. |
F. Discoveries show that messages are carried by the central nervous system in the brain. |
G. Using the most advanced technology, detailed images were produced. |
