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.

s a mystery. All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those rounds, and which could be written down. Those sounds, whether spoken or written in letters we call words.

The power of words, then, lies in their combinations--the things they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and sad events of our past; and the more we read and learn, the more the number of words that mean something to us increases.

Great writers are those who not only have great thoughts, but also express these thoughts in words which appeal powerfully to our minds and feelings. This charming and telling use of words is what we call literary (文字的) style. Above alt, the real poet is a master of words. He can convey his meaning in words which sing like music, and which by their position and association can move men to tears. We should therefore learn to choose our words carefully and use them accurately, or they will make our speech silly and rude.

The origin of language ______.

A．is reflected in. sounds and letters

B．is handed down from generation to generation

C．dates back to the prehistoric period

D．is a problem not yet solved

Passage 2 Questions 6 to 10 are based on the following passage:

How men first learned to invent words is unknown; in other words, the origin of language is a mystery. All we really know is that men, unlike animals, somehow invented certain sounds to express thoughts and feelings, actions and things, so that they could communicate with each other; and that later they agreed upon certain signs, called letters, which could be combined to represent those sounds, and which could be written down. Those sounds, whether spoken, or written in letters we call words.

The power of words, then, lies in their combinations — the things they bring up before our minds. Words become filled with meaning for us by experience; and the longer we live, the more certain words recall to us the glad and sad events of our past; and the more we read and learn, the more the number of words that mean something to us increases.

Great writers are those who not only have great thoughts but also express these thoughts in words which appeal powerfully to our minds and feelings. This charming and telling use of words is what we call literary (文字的) style. Above all, the real poet is a master of words. He can convey his meaning in words which sing like music, and which by their position and association can move men to tears. We should therefore learn to choose our words carefully and use them accurately, or they will make our speech silly and rude.

species of plant and several hundreds thousands types of living things. But only a tiny percentage of these were ever domesticated. Modern shops have hastened a trend towards specialization which began in the earliest days of agriculture. The food of the rich countries has become cheaper relative to wages. It is speedily distributed in supermarkets. But the choice annually becomes less and less great. Even individual foods themselves become more standardized. We live in the world of carrot specially blunted in order to avoid making a hole in the bag, and the tomato grown to meet a demand for a standard weight of weighting tomatoes to a kilo. Siri von Reis asks: "Only the three major cereals (谷物类食物) and perhaps ten other widely cultivated species stand between famine and survival for the world's human population and a handful of drug plants has served Western civilization for several thousand years. A rather obvious question arises: Are we missing something？" After all, there are 800 000 species of plant on earth.
