Prehistoric people are human beings who lived before writing was invented about 5,500 years ago. Writing 26 people to record information they wished to save,27 descriptions of events in their lives.28 this way, the invention of writing marked the beginning of history. The period before human beings learned to write is called prehistory.

Scientists first discovered evidence of prehistoric people in the mid-1800’s .Most of this evidence 29 ancient, sharp-edged stone tools and fossilized (已变成化石的)bones of prehistoric people.

30 scientists collected more fossils of prehistoric people, they began to form. a clearer 31 of what these early people looked like. For example, scientists learned that early human beings had smaller brains than most modern men and women have. This evidence indicated 32 humans had evolved-that is, modified their physical structure over time. Scientists developed a set of ideas about human origins 33 the theory of human evolution. This theory states that as the 34 of the prehistoric world changed, our prehistoric ancestors went 35 a series of changes that resulted in the first human beings. They, 36 , evolved into modern human beings.

Evidence of prehistoric people is 37 and difficult to find. Scientists must 38 their theory on this extremely limited evidence. As a result, scientists cannot 39 present a detailed picture of early human life. 40, new discoveries sometimes disprove theories that scientists already hold.

阅读材料，回答题。

In what now seems like the prehistoric times of computer history, the early postwar era(战后时期), there was a quite widespread concern that computers would take over the world from man one day. Already today, less than forty years later, as computers are relieving us of more and more of the routine tasks in business and in our personal lives, we are facing with a less dramatic but also less foreseen problem. People tend to be over trusting (过分信任) of computers and are reluctant to challenge their authority. Indeed, they behave as if they were hardly aware that wrong buttons maybe pushed, or that a computer may simply malfunction(失灵).

Obviously, there would be no point in investing(投入) in a computer if you had to check all its answers, but people should also rely on their own internal computers and check the machine when they have the feeling that something has gone wrong. Questioning and routine double checks must continue to be as much a part of good business as they were in pre computer days. Maybe each computer should come with the following warning: for all the help this computer may provide, it should not be seen as a substitute for fundamental thinking and reasoning skills.

What is the main purpose of this passage？查看材料

A.To look back to the early days of computers

B.To explain what technical problems may occur with computers

C.To discourage unnecessary investment in computers

D.To warn against the blindness to the probable shortcomings of computers

Text 3 When prehistoric man arrived in new parts of the world, something strange happened

Text 3

When prehistoric man arrived in new parts of the world, something strange happened to the large animals. They suddenly became extinct. Smaller species survived. The large, slow-growing animals were easy game, and were quickly hunted to extinction. Now something similar could be happening in the oceans.

That the seas are being overfished has been known for years. What researchers such as Ransom Myers and Boris Worm have shown is just how fast things are changing. They have looked at half a century of data from fisheries around the world. Their methods do not attempt to estimate the actual biomass (the amount of living biological matter) of fish species in particular parts of the ocean, but rather changes in that biomass over time. According to their latest paper published in Nature, the biomass of large predators (animals that kill and eat other animals) in a new fishery is reduced on average by 80% within 15 years of the start of exploitation. In some long-fished areas, it has halved again since then.

Dr. Worm acknowledges that the figures are conservative. One reason for this is that fishing technology has improved. Today’s vessels can find their prey using satellites and sonar, which were not available 50 years ago. That means a higher proportion of what is in the sea is being caught, so the real difference between present and past is likely to be worse than the one recorded by changes in catch sizes. In the early days, too, longlines would have been more saturated with fish. Some individuals would therefore not have been caught, since no baited hooks would have been available to trap them, leading to an underestimate of fish stocks in the past. Furthermore, in the early days of longline fishing, a lot of fish were lost to sharks after they had been hooked. That is no longer a problem, because there are fewer sharks around now.

Dr. Myers and Dr. Worm argue that their work gives a correct baseline, which future management efforts must take into account. They believe the data support an idea current among marine biologists, that of the “shifting baseline.” The notion is that people have failed to detect the massive changes which have happened in the ocean because they have been looking back only a relatively short time into the past. That matters because theory suggests that the maximum sustainable yield that can be cropped from a fishery comes when the biomass of a target species is about 50% of its original levels. Most fisheries are well below that, which is a bad way to do business.

31. The extinction of large prehistoric animals is noted to suggest that ________.

[A] large animal were vulnerable to the changing environment

[B] small species survived as large animals disappeared

[C] large sea animals may face the same threat today

[D] slow-growing fish outlive fast-growing ones

第7题

We all associate colors with feelings and attitudes. In politics, dark blue often means "t

radition", and red means "social change". But blue can also mean sadness (I'm feeling blue). White is often for purity, although in China white is worn for funerals, and red is used to express the joy of a wedding, in western Europe white is worn at weddings and black for funerals. Advertisers are aware of the importance of selecting colors according to the way people react to them. Soap powders come in white and light blue packets (clean and cold, like ice); cereals often come in brown packets (tike wheat fields), but cosmetics never come in brown jars (dirty).

Where do these ideas come from？ Max Luscher from the University of Geneva believes that in the beginning life was dictated by two factors beyond our control: night and day. Night brought passivity, and a general slowing down of metabolism; day brought with it the possibility of action, and increased in the metabolic rate, thus providing us with energy and initiative. Dark blue, therefore, is the color of quietness and passivity, bright yellow the color of hope and activity.

In prehistoric times, activity as a rule took one of two forms: either we were hunting and at- tacking, or we were being hunted and defending ourselves against attack. Attack is universally re- presented by the color red; serf-preservation by its complement green.

In Luseher's view, the association of colors with feeling and attitudes can be traced back to______.

A．the association of day and night with passivity and action in ancient time

B．the association of black with funerals in western Europe

C．the association of white with purity in some countries

D．the association of red with joy in China
