If we were asked exactly what we were doing a year ago，we should probably have to say that we could not remember. But if we had kept a book and had written in it an account of what we did each day, we should be able to give an answer to the question.
It is the same in history. Many things have been forgotten because we do not have any written account of them. Sometimes men did keep a record of the most important happenings in their country，but often it was destroyed by fire or in a war. Sometimes there was never any written record at all because the people of that time and place did not know how to write. For example, we know a good deal about the people who lived in China 4, 000 years ago, because they could write and leave written records for those who lived after them. But we know almost nothing about the people who lived even 200 years ago in central Africa because they had not learned to write.
Sometimes, of course, even if the people cannot write, they may know something of the past. They have heard about it from older people and often songs and dances and stories have been made about the most important happenings, and these have been sung and acted and told for many generations, for most people are proud to tell what their fathers did in the past. This we may call ？remembered history ” . Some of it has now been written down. It is not so exact or so valuable to us as written history is, because words are much more easily changed when used again and again in speech than when copied in writing. But if there are no written records, such spoken stories are often very helpful.
Which of the following is NOT suggested in the passage？
A.Written history is more reliable.
B.Written records play an important role in learning about history.
C.A written account of our daily activities helps to answer many questions.
D.Where there are no written records, there is no history.

B.people there ignored the importance of keeping a record
C.people there did not know how to write
D.the written records were perhaps destroyed by a fire
“ Remembered history” refers to ______.A.history based on a person’s imagination
B.stories of important happenings passed down from mouth to mouth
C.songs and dances about the most important events.
D.both B and C
“ Remembered history” is regarded as valuable only when ______.A.it is written down
B.No written account is available
C.it proves to be timely
D.People are interested in it
It is suggested that we could have learned more about our past if ancient people had ______.A.kept a written record of every past event
B.burnt their written records in wars
C.told exact stories of the most important happenings

Cars are lots of fun, but they could also be dangerous. We have to be careful when we drive them or ride in them.
It's always a good idea to put on your seat belt when you're in a car. Why？ Think about this example: You put an egg on a skateboard(滑板) and give it a push. If the skateboard hits a stone, it will stop, but the egg won't. It will fly through the air, hit the ground and break.
Now, think what would happen if you tied the egg to the skateboard. When the skateboard hits a stone, the egg won't go flying. It will stay safely on the skateboard.
Volvo, a famous Swedish carmaker, was the first to use seat belts in 1949. Air bags are also very important for car safety, because sometimes a seat belt isn't enough. If the car is going really fast and runs into something, seat belts could even hurt the people who wear them.
Most newer cars have air bags in front of and next to the seats. When a car hits something, its air bags will come out quickly--in less than one second--to keep the people inside safe.
