other tools out of wood. Human beings needed to use tools because they did not have sharp teeth like other meat eating animals, such as lions and tigers. Tools helped people to get food more easily.
Working with tools also helped to develop human intelligence. The human brain grew bigger, and human beings began to invent more and more tools and machines.The stone chip was one of the first tools that people used, and perhaps it is the most
important. Some scientists say that it was the key to success of mankind. Since 1960 a new kind of tool has appeared. This is the silicon chip—a little chip of silicon crystal. It is smaller than a fingernail, but it can store more than a million“bits” of information. It is an electronic brain. Every year these chips get cleverer, but their size gets smaller, and their cost gets less.
They are used in watches, calculators and intelligent machines that we can use in many ways. In the future we will not need to work with tools in the old way. Machines will do everything for us. They will even talk and play games with us. People will have plenty of spare time. But what will they do with it? Human beings used stone chips for more than two million years, but human life changed very little in that time. We have used silicon chips for only a few years, but life is changing faster every day. What will life be like twenty years from now? What will the world be like two million years from now?
1. The stone chip is thought to be the most important tool because it ______. A. was one of the first toolsB. developed human capabilities
C. led to the invention of machinesD. was crucial to the development of mankind 2. At the end of the passage the author seems to suggest that life in future is______. A. disastrous B. unpredictableC. exciting D. colorful 1. D) 2. B)

California is a land of variety and contrast. Almost every type of physical land feature, sort of arctic ice fields and tropical jungles can be found within its borders. Sharply contrasting types of land often lie very close to one another. People living in Bakersfield, for instance, can visit the Pacific Ocean and the coastal plain, the fertile San Joaquin Valley, the arid Mojave Desert, and the high Sierra Nevada, all within a radius of about 100 miles.
In other areas it is possible to go snow skiing in the morning and surfing in the evening of the same day, without having to travel long distance.

Contrast abounds in California. The highest point in the United States (outside Alaska) is in California, and so is the lowest point (including Alaska).Mount Whitney, 14,494 feet above sea level, is separated from Death Valley, 282 feet below sea level, by a distance of only 100 miles. The two areas have a difference in altitude of almost three miles. California has deep, clear mountain lakes like Lake Tahoe, the deepest in the country, but it also has shallow, salty desert lakes. It has Lake Tulainyo, 12,020 feet above sea level, and the lowest lake in the country, the Salton Sea, 236 feet below sea level. Some of its lakes, like Owens Lake in Death Valley, are not lakes at all: they are dried-up lake beds. In addition to mountains, lakes, valleys, deserts, and plateaus, California has its Pacific coastline, stretching longer than the coastlines of Oregon and Washington combined.
1. Which of the following is the lowest point in the United States? A. Lake Tulainyo.B. Mojave desert.C. Death Valley.D. The Salton Sea.
2. Where is the highest point in the United States located?
A. Lake Tahoe.B. Sierra Nevada.C. Mount Whitney.D. Alaska. 3. How far away is Death Valley from Mount Whitney?
A. About 3 miles.B. Only 100 miles.C. 282 feet.D. 14,494 feet.
4. Which of the following is NOT mentioned in the passage as being within a radius of about 100 miles of Bakersfield?A. The Pacific Ocean.B. San Joaquin Valley.C. Mojave Desert.D. Oregon and Washington.
5. Which statement best demonstrates that California is a land of variety and contrast?
A. The highest lake in California is Lake Tulainyo.
B. It is possible to go surfing and snow skiing in some parts of California without having to travel long distance.
C. Sierra Nevada, San Joaquin Valley, Mojave Desert and the Pacific Ocean all lie within a radius of about 100 miles.
D. Owens Lake, in Death Valley, is not really a lake at all. 1. C) 2. D) 3. B) 4. D) 5. C)

Most earthquakes occur within the upper 15 miles of the earth's surface. But earthquakes can and do occur at all depths to about 460 miles. Their number decreases as the depth increases. At about 460 miles one earthquake occurs only every few years. Near the surface earthquakes may run as high as 100 in a month, but the yearly average does not vary much. In comparison with the total number of earthquakes each year, the number of disastrous earthquakes is very small.
The extent of the disaster in an earthquake depends on many factors. If you carefully build a toy house with an erect set, it will still stand no matter how much you shake the table. But if you build a toy house with a pack of cards, a slight shake of the table will make it fall. An earthquake in Agadir, Morocco, was not strong enough to be recorded on distant instruments, but it completely destroyed the city. Many stronger earthquakes have done comparatively little damage. If a building is well constructed and built on solid ground, it will resist an earthquake. Most deaths in earthquakes have been due to faulty building construction or poor building sites. A third and very serious factor is panic. When people rush out into narrow streets, more deaths will result.
The United Nations has played an important part in reducing the damage done by earthquakes. It has sent a team of experts to all countries known to be affected by earthquakes. Working with local geologists and engineers, the experts have studied the nature of the ground and the type of most practical building code for the local area. If followed, these suggestions will make disastrous earthquakes almost a thing of the past.
There is one type of earthquake disaster that little can be done about. This is the disaster caused by seismic sea waves, or tsunamis. (These are often called tidal waves, but the name is incorrect. They have nothing to do with tides.) In certain areas, earthquakes take place beneath the sea. These submarine earthquakes sometimes give rise to seismic sea waves. The waves are not noticeable out at sea because of their long wave length. But when they roll into harbors, they pile up into walls of water 6 to 60 feet high. The Japanese call them \meaning \waves\because they reach a sizable height only in harbors.
Tsunamis travel fairly slowly, at speeds up to 500 miles an hour. An adequate warning system is in use to warn all shores likely to be reached by the waves. But this only enables people to leave the threatened shores for higher ground. There is no way to stop the oncoming wave. 1. Which of the following CANNOT be concluded from the passage? A. The number of earthquakes is closely related to depth. B. Roughly the same number of earthquakes occur each year.

I live in the land of Disney, Hollywood and year-round sun. You may think people in such a glamorous, fun-filled place are happier than others. If so, you have some mistaken ideas about the nature of happiness. Many intelligent people still equate happiness with fun. The truth is that fun and happiness have little or nothing in common. Fun is what we experience during an act. Happiness is what we experience after an act. It is a deeper, more abiding emotion.
Going to an amusement park or ball game, watching a movie or television, are fun activities that help us relax, temporarily forget our problems and maybe even laugh. But they do not bring happiness, because their positive effects end when the fun ends.
I have often thought that if Hollywood stars have a role to play, it is to teach us that happiness has nothing to do with fun. These rich, beautiful individuals have constant access to glamorous parties, fancy cars, expensive homes, everything that spells “happiness”. But in
