There are robots all around us. Some do very 1 jobs like flying airplanes and driving subway trains.
And some do simple jobs.
When an automatic washing machine 2 , water goes in. The machine waits until the water is hot 3
washing the clothes. It does this by "feedback" (反馈). Information about what"s 4 is "fed back" into
the robot to tell it 5 next.
Our eyes, ears and other senses (感官) are 6 feedback. They tell us 7 round us. So robots are
like people in 8 ways. They work and they have feedback.
But 9 robots look like people. Many are 10 ways. Robots control (控制) the temperature of our
houses, our cookers, our hot water systems. We can 11 the controls to the temperature we want. The
robot does 12 . Its feedback usually come 13 thermostat (自动调温器).
Our kind of thermostat is a strip of metal (金属条), which bends (弯曲) when it gets hot. At the right
temperature, it bends just enough 14 a switch. This turns off the heat. As the air around it gets 15 ,
the metal gets straight, and this turns the heat on again. |

Well, when a rabbit sees something dangerous, it runs away. Its tail moves up and down as it runs.
When other rabbits see this tail moving up and down, they ran, too. They know there is danger. The
rabbit has told them something without making a sound. It has given them a signal.
Many other animals use this kind of language. When a bee finds some food, it goes back to his home.
It can"t tell the other bees where the food is by speaking to them, but it does dance in the air. This tells
the bees where the food is.
But animals say things by making sounds. A dog barks, for examples, when a stranger comes near.
A cat purrs (发出呼噜呼噜的声音) when pleased. Some birds make several different sounds, each with
its own meaning.
But human beings have something that no animals have-a large number of words about things, actions,
feelings or ideas. We are able to give each other information to tell or inform other people what is in our
mind or how we feel. By writing words down we can remind ourselves of the things that have happened,
or send messages to people far away. No animals can do this. No animals has the wonderful power of
language.
No one knows how man learned to make words. Somehow he learned to make them. As centuries
went by, he made more and more new words. This is what we mean by language.
People in different countries made different kinds of words. Today there are about fifteen hundred
different languages in the world. A very large English dictionary, for examples, contains four or five
hundred thousand words. But we don"t know all these. The words we know are called vocabulary. We
should try to make our vocabulary larger. Read as many books as possible. When we met a new word,
look it up in the dictionary. A dictionary is the most useful book. | | 1. What"s the meaning of the underlined word? | | [ ] | A. 标语

earthquakes in world history took place in Japan in 1923. The shock and fires caused by it destroyed
much of Tokyo and Yokohama and left more than 7000 dead. Other countries do not have many. For
examples, there are few earthquakes in Britain, France, Germany.
There is often a great noise during an earthquake, but it is not always. The earth rocks. Houses fall
down. Railway lines are broken. Sometimes many people are killed in an earthquake. People think earthquakes
often happen near volcanoes (火山), but this is not always true. The centers of some are under the sea.
The bottom of the sea suddenly moves. The powerful forces inside the earth break the rocks. The coast
is rocking and great waves are caused there. These waves travel long distances and rush over the land
when they reach it. They are strong enough to break down houses and other buildings; sometimes they
break more buildings than earthquake itself.
What kind of building stands up best in an earthquake? A building with concrete (水泥) walls is perhaps
the best. A steel frame (框架) will make it even stronger. The frame holds the different parts together and
the walls do not easily fall. There is less chance of fire because concrete and steel (钢材) does not burn.
This kind of building is the safest. Today modern concrete and steel apartment buildings are commonly
seen in cities of Japan.
1. Why do we say that an earthquake is terrible?
_____________________________________________________________________.
2. What kind of building is the safest for us to live in against earthquakes?
_____________________________________________________________________.
3. Which country has the largest number of earthquakes, Britain, Japan, or France?
_____________________________________________________________________.
4. 判断正误：正确的在括号里写T，错误写F。
( ) The text mainly tells us how to protect ourselves when the earthquake happens.
5. Put the underlined sentences into Chinese.

and other kinds of health problems during this month. In the Northeast and the Middle West, it is very hot at
some times and every cold at other times. People in these states have more heart trouble after the weather
changes in February or March.
The weather can also influence intelligence. For example, in a 1983 report by scientists, IQ (智商) of a
group students were very high when a very strong wind came, but after the strong wind, their IQ was 10%
below. The wind can help people have more intelligence. Very hot weather, on the other hand (另一方面),
can make it lower. Students in many schools of the United States often get worse on exams in the hot
months of the year (July and August).
Weather also has a strong influence on people"s feelings. Winter may be a bad time for thin people.
They usually feel cold during these months. They might feel unhappy during cold weather. But fat people
may have a hard time in hot summer. At about 18C, people become stronger.
Low air pressure (气压) may make people forgetful. People leave more bags on buses and in shops
on low-pressure days. There are a "good weather" for word and health. People feel best at a temperature
of about 18 centigrade (摄氏度).
