Inland waters may be grouped into two general classes: standing waters and flowing waters. As is often the case, the boundary between these two classes is not sharp and clear. A pond is an example of standing water. But most ponds are fed by springs or brooks and most have an outlet. Thus some current of changing water flows through them. On the other hand, a river is an example of flowing water. In some places, however, a river may have such a slow current that it is very difficult to detect.
Standing inland waters differ in size, in age, and in many abiotic environmental characteristics. They range in size from roadside puddles to the Caspian Sea. Puddles may last for only a few days or weeks; ponds, for a few hundred to a thousand years. In general, lakes are older, though the waters of some tropical “lakes” disappear completely during each dry season. Standing waters vary from very shallow to very deep, from clear to muddy, from fresh to salty.
In flowing waters we roughly distinguish between brooks, creeks, and rivers. The size and age of flowing waters are unimportant. Speed of flow, clearness, oxygen content, and other chemical characteristics are used by scientists in studying flowing-water ecosystems.
1.According to the passage, which of the following characteristics of flowing waters is unimportant?
A. Clarity. B. Size. C. Speed of flow. D. Oxygen content.
2.The word “abiotic” in paragraph 2 can best be replaced by ______.
A. nonliving B. living C. coastal D. inland
3.Which of the following statements is true?
A. Usually the water in a river flows into a pond.
B. Scientists only study flowing-water ecosystems.
C. Usually ponds last much longer than puddles.
D. The Caspian Sea is considered as an example of flowing water.
4.From this passage we may know that the distinction between standing waters and flowing waters ______.
A. depends on how people name the waters
B. is clear
C. depends on the seasons
D. is hard to make
5.This passage mainly tells us that ______.

B. lakes and rivers are flowing waters
C. age and size of flowing waters are important

All Eskimos live most of their lives close to sea or fresh water. They may follow game inland for several hundred miles, but they always return to the shores of rivers, lakes, or seas. Eskimo land has a bare look. Large rocks, pebbles, and sand cover much of the surface. Plants called lichen (地衣) grow on the rocks, and where there is enough soil, grass, flowers, and even small bushes manage to live. No trees can grow on Eskimo land, so geographers sometimes call it the Arctic plains. There are some animals in Eskimo land, such as rabbits, which eat the plants. Other animals, like the white fox and the gray wolf, eat the rabbits. The Eskimo is a meat-eater, too, and may even eat a wolf when food is scarce.
The Eskimo year has two main parts: a long, cold winter and a short, cool summer. Spring and fall are almost too short to be noticed. Summer is the best time, as food is usually plentiful. But it is also the time when Eskimos are very busy. Winter is never far away, and the men must bring home extra meat for the women to prepare and store, for seldom can enough animals be killed in winter to feed a family.
The Far North is sometimes called the land of the midnight sun. This is true in the middle of summer, for between April 21st and August 21st the sun never sets in Northern Greenland. But in midwinter the Far North is a land with no sunshine at all. Around Oct. 21st the Eskimos of Northern Greenland see the sun set directly south of them, and they don’t see it again until February 22nd. All places on earth get about the same amount of daylight during a year. As a result, if summer is lighter, winter has to be darker.
Winter nights in the Far North are seldom pitch-black. As in the rest of the world, the stars and moon provide a little light. The northern lights also help the Eskimo to see. And with the ground covered with snow, even a little light is reflected back to the Eskimo’s eyes.
1.Which of the following statements is NOT true?
A.Eskimos do not usually eat wolves. |
B.Eskimos like to chase one another. |
C.Eskimos depend heavily on water. |
D.Eskimos are meat-eaters. |
2.What’s the meaning of the underlined words “pitch-black” in Paragraph 4?
A.Dark with a little light. |
B.A little dark. |
C.Not dark at all. |
D.Extremely dark. |
3.From the passage, we can infer all of the following EXCEPT that_______.
A.Eskimos are more likely to eat wolves in summer |
B.Eskimo women are responsible for housework |
C.meat is the main source of food for the Eskimo |
D.hunting is an important part of Eskimo life |

In general, people talk about two groups of colors: warm colors and cool colors. Researchers in psychology think that there are also two groups of people: people who prefer warm colors and people who prefer cool colors.
The warm colors are red, orange and yellow. Where there are warm colors and a lot of light, people usually want to be active. People think that red, for example, is exciting. Sociable people, those who like to be with others, like red. The cool colors are green, blue and violet. These colors, unlike warm colors, are relaxing. Where there are cool colors, people are usually quiet. People who like to spend time alone often prefer blue.
Red may be exciting, but one researcher says that time seems to pass more slowly in a room with warm colors than in a room with cool colors. He suggests that a warm color, such as red or orange is a good color for a living room or restaurant. People who are relaxing or eating do not want time to pass quickly. Cool colors are better for offices or factories if the people who are working there want time to pass quickly. Researchers do not know why people think some colors are warm and other colors are cool.
However, almost everyone agrees that red, orange, and yellow are warm and that green, blue, and violet are cool. Perhaps warm colors remind people of warm days and the cool colors remind them of cool days. Because in the north the sun is higher during summer, the hot summer sunlight appears yellow.
1.Which of the following colors belong to cool colors?
A. Blue, violet B. Yellow, green
C. Black, blue. D. Brown, white
2.Which of the following statements is not true?
A. Sociable people like warm colors.
B. Warm colors can make people excited.
C. People who like to be with others don’t like red.
D. Where there are warm colors, people want to be active.
3.Which is the right color for different rooms?
A. Red or orange for offices.
B. Orange for dining rooms.
C. Blue for bedrooms.
D. Red for studies
4. Which of the following is the best title for the passage?
A. Two groups of colours B. Cool colours
C. Warm colours D. Colours and people

There seems to be a general assumption that brilliant people cannot stand routine ; that they need a varied , exciting life in order to do their best . It is also assumed that dull people are particularly suited for dull work . We are told that the reason the present-day young complain so loudly about the dullness of jobs is that they are better educated and brighter than the young of the past .
Actually , there is no evidence that people who achieve a lot desire , let alone live , colorful lives . The opposite is nearer the truth . Einstein worked out his theory of relativity while serving as a clerk in a Swiss patent office . Immanuel Kant’s(康德)daily life was a dull routine . The housewives of Konigsberg set their clocks when they saw him pass , on his way to the university . He took the same walk each morning , rain or shine . The greatest distance Kant ever traveled was sixty miles from Konigsberg .
It may be true that work on the assembly line(流水线)dulls the abilities and empties the mind , and the cure is only fewer hours of work at higher pay . But during fifty years as a workingman , I have found dull routine coexisting with an active mind . While doing dull , repetitive work by the water , I could talk with my partners and compose sentences in my mind , all at the same time . Chances are that had my work been too interesting I could not have done any thinking and composing at work or even on my own time after returning from work .
People who find dull jobs unbearable are often dull people who do not know what to do with themselves at leisure . Children and mature people will get used to dull routine , while the adolescent , who has lost the child’s ability for concentration and is without the inner resources of the mature , needs excitement and novelty to get rid of boredom .
1. It can be inferred from Paragraph 2 that __________ .
A. great minds hate to live colorful lives
B. Einstein worked out his theory in a university
C. Kant only took the same walk on rainy and sunny days
D. Kant might pass Konigsberg every day at the same time
2.How does the author feel about his repetitive work by the water ?
A. It made his mind empty .
B. It was well-paid but too demanding .
C. It worked well with his active mind .
D. It was too interesting to think of anything else .
3.The reasons why youngsters dislike dull work include the following EXCEPT that they __________ .
A. are not mature enough
B. think themselves smart
C. often complain about others
D. don’t know how to spend spare time
4.What is the purpose of the passage ?
