About ten men in every hundred suffer from color blindness in some way. Women are luckier; only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman!
There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shadows of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green - a strange world indeed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called “cones”. These help us to see in a bright light and to tell difference between colors. There are also millions of “rods”, but these are used for seeing when it is near dark. They show us shape but no color.
Some insects have favorite colors. Mosquitoes prefer blue to yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.
【小題1】The passage is mainly about _____________.

A.color and its surprising effects.

【小題2】According to the passage, with the help of the “cones”, we can_______________.

【小題3】Why do some people say it is safer to be driven by women?
A.Women are more careful.
B.There are fewer color-blind women
C.Women are fonder of driving than men.
D.Women are weaker but quicker in thinking.

A.Not all of them have the same problem in recognizing color.
B.None of them can see deep red.
C.None of them can tell the difference between blue and green.
D.All of them see everything in shades of green.

科目:高中英語 來源:2016屆四川成都南片區六校聯考高一上學期期中考試英語試卷(解析版) 題型:閱讀理解

This year some twenty-three hundred teenagers (young people aged from 13 to 19) from all over the world will spend about ten months in US homes. They will attend US schools, meet US teenagers, and form impressions of the real America. At the same time, about thirteen hundred American teenagers will go to other countries to learn new languages and gain a new understanding of the rest of the world.

         Here is a two-way student exchange in action. Fred, nineteen, spent last year in Germany with George’s family. In turn, George’s son Mike spent a year in Fred’s home in America.

Fred, a lively young man, knew little German when he arrived, but after two months’ study, the language began to come to him. Schools were completely different from what he had expected—much harder. Students rose respectfully when the teacher entered the room. They took fourteen subjects instead of the six that are usual in the United States. There were almost no outside activities.

Family life, too, was different. The father’s word was law, and all activities were around the family rather than the individual(個人). Fred found the food too simple at first. Also, he missed having a car.

    “Back home, you pick up some friends in a car and go out and have a good time. In Germany, you walk, but you soon learn to like it.”

    At the same time, In America, Mike, a friendly German boy, was also forming his idea.“I suppose I should criticize(批評) American schools,” he says. “It is far too easy by our level. But I have to say that I like it very much. In Germany we do nothing but study. Here we take part in many outside activities. I think that maybe your schools are better in training for citizens(公民). There ought to be some middle ground between the two.

1.The world exchange programme is mainly to ________.

A.help teenagers in other countries know the real America

B.send students in America to travel in Germany

C.have teenagers learn new languages

D.let students learn something about other countries

2.Fred and Mike agreed that ________.

A.American food tastes better than German food.

B.Americans and Germans were both friendly

C.German schools were harder than American schools

D.There were more cars on the streets in America

3.What is special in American schools is that ________.

A.there is some middle ground between the two teaching buildings

B.students go outside to enjoy themselves in a car

C.students usually take fourteen subjects in all

D.there are a lot of after-school activities

4.After experiencing the American school life, Mike thought _________.

A.German schools trained students to be better citizens

B.A better education should include something good from both America and Germany

C.American schools were not as good as German schools

D.The easy life in the American schools was more helpful to students

科目:高中英語 來源:2010年江西省高三10月月考英語卷 題型:閱讀理解

Scientists in Canada say big fish have almost disappeared from the world since the start of industrial(產業的) fishing in the 1950s. The scientists found the numbers of some kinds of large fish have dropped by ninety percent in the past fifty years.

The study took ten years. The researchers gathered records from fishing businesses and governments around the world. The magazine Nature published the findings.

The scientists say the common method called long line fishing ravages the populations of large fish. This method involves many fishing lines connected to one boat. These wires can be nearly one hundred kilometers long. They hold thousands of sharp metal hooks to catch fish.

Long line fishing is especially common in the Japanese fishing industry. Records showed that Japanese boats used to catch about ten fish for every one hundred hooks. But long line fishing boats now might only catch one fish per hundred hooks.

The scientists say industrial fishing can destroy groups of fish much faster than in the past. The study suggests that whole populations can disappear almost completely from new fishing areas within ten to fifteen years.

Ransom Myers and Boris Worm of Dalhousie University in Nova Scotia led the study with the University of Kiel in Germany. Worm says the destruction could lead to a complete reorganization of ocean life systems. Meyers says the decreased numbers of large fish are not the only worry. He says even populations that are able to reproduce do not get the chance to live long enough to grow as big as their ancestors. He says not only are there fewer big fish, but also they are smaller than those of the past.

  It’s the end of this program ,Thank you for your listening.

1.What’s the best title for the passage?

       A. Big fish are disappearing            B. Long—line fishing in Japan

A. Fish can disappear almost completely from new fishing areas.

B. Now long—line fishing boats might catch one fish per hundred hooks.

C. Fish now don’t have the chance to grow big enough.

D. Scientists spent ten years studying the populations of large fish.

3.What can we learn from the passage?

A. The number of big fish started to drop greatly about fifty years ago.

B. The study was started by Boris Worm of Dalhousie alone.

C. There will be no big fish left in fifty years .

D. Japaneses people have stopped catching big fish.
