Maybe 10 years old Elizabeth put it best when she said to her father," But Dad, you can't be healthy if you're dead."
Dad, in a hurry to get home before dark so he could go for a run, had forgotten to wear his safety belt—a mistake 75% of the US population make every day. The big question is why.
There have been many myths about safety belts since their first appearance in cars some forty years ago. The following are three of the most common.
Myth Number One: It's best to be "thrown clear "of a serious accident.
Truth: Sorry, but any accident serious enough to" throw you clear" is also going to be serious enough to give you a very bad landing, and chances are you'll have travelled through a windshield or door to do it. Studies show that chances of dying after a car accident are twenty-five times greater in cases where people are" thrown clear".
Myth Number Two: Safety belts" trap" people in cars that are burning or sinking in water.
Truth: Sorry again, but studies show that people knocked unconscious for not wearing safety belts have a greater chance of dying in these accidents. People wearing safety belts are usually protected to the point of having a clear head to free themselves from such dangerous situations, not to be trapped in them.
Myth Number Three: Safety belts aren't needed at a speed of less than 30 miles per hour (mph).
Truth: When two cars travelling at 30 mph hit each other, an unbelted driver would meet the windshield with a force headfirst into the ground from a height of 10 meters.
Why did Elizabeth say to her father, "But, Dad, you can't be healthy if you are dead"？
A．He was driving at great speed.
B．He was running across the street.
C．He didn't have his safety belt on.
D．He didn't take his medicine on time.

To us it seems so natural to put up an umbrella to keep the water off when it rains. But actually the umbrella was not invented as protection against rain. Its first use was as a shade against the sun.
Nobody knows who first invented it, but the umbrella was used in very ancient times. Probably the first to use it were the Chinese, way back in the eleventh century B.C.
We know that the umbrella was used in ancient Egypt and Babylon as a sunshade. And there was a strange thing connected with its use: it became a symbol of honor and authority. In the Far East in ancient times, the umbrella was allowed to be used only by royalty or by those in high office.
In Europe, the Greeks were the first to use the umbrella as a sunshade. And the umbrella was in common use in ancient Greece. But it is believed that the first persons in Europe to use the umbrella as protection against the rain were the ancient Romans.
During the Middle Ages, the use of the umbrella practically disappeared. Then it appeared again in Italy in the late sixteenth century. And again it was considered a symbol of power and authority. By 1680, The umbrella appeared in France, and later on in England.
By the eighteenth century, the umbrella was used against rain throughout most of Europe. Umbrellas have not changed much in style. during all this time, though they have become much lighter in weight. It wasn't until the twentieth century that women's umbrellas began to be made, in a whole variety of colors.
The first use of umbrella was as ______.
A．protection against rain
B．a shade against the sun
C．a symbol of power
D．a symbol of honor

When you send a letter or a postcard, you have to put stamps on the envelope or on the card. When did people first begin to use stamps？ Who was the first to think of this idea？
In the early nineteenth century, people did not use stamps. They had to pay postage (邮费) when they received letters. Sometimes they didn't want to receive a letter at all, but they had to pay money for it. They were unhappy about this. The postage was high at that time, because the post offices had to send many people to get the postage.
Rowland Hill was a school teacher in England. He was the first to think of using stamps in 1850s. He thought it would be much easier for people to use stamps. People could go to the post office to buy stamps and put them on envelopes before they sent the letters. The post office could just put seals (邮戳). on the stamps so that people could not use the stamps again. In this way, the post office did not need to send post men to get postage. It only needed fewer postmen to send letters.
People began to use stamps ______.
A．at the beginning of the nineteenth century
B．in the middle of the nineteenth century
C．more than two hundred years ago
D．when people first sent letters and postcards.
