One day while driving from my home to work, I noticed a car in front of me had a wobbly(不稳定的)wheel. It was clear that the wheel had been changed recently and had not been fixed correctly. On a slow road this would not show much of a problem but 1 knew a highway was coming soon. There the traffic would move much faster and the driver would be in danger 25 the wheel could come off at that speed.

I was driving a large jeep at the time and the car in front was a small one driven by a young lady on her own. So as I tried to flash (闪) my lights and wave her to pull over, I was worried that she wouldn't pull over on the road side when she found in her mirror a single man chasing(追)her down in a jeep and waving for her to pull over.

Thankfully she trusted more in the good nature of people and pulled over where I could explain the problem. She said the wheel was changed only the night before and that she would pull into the nearest garage (修车间) where the repairman had tools to fix the wheel correctly.

My belief is that the act of kindness was hers but not mine. How so? Well, it was she who chose to believe in the possibility that people are good over the belief that bad things would come from being waved over to the side of the road by strangers.

I am glad I was able to wave her down in time and so a serious accident might have been avoided. But I am even happier that she believed in a stranger

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 the 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 in the 11th century BC.

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. In the Far East in ancient times, the umbrella was allowed to be used only by royal people or by those in high class.

In Europe, the Greeks were the first to use the umbrella as a sunshade. And the umbrella was commonly used 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 as a symbol of power. By 1680, the umbrella appeared in France and later in England. By the eighteenth century, the umbrella was used against the rain in all parts 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 different kinds of colors.

1.The underlined word “it” in Paragraph 5 refers to ________.

A.Italy B.the 16th century C.the umbrella D.the use of the umbrella

2.The umbrella was first widely used against the rain ________ around Europe.

3.Which of the following statements is true about the umbrella?

A.Some researchers exactly know who the inventor of the umbrella was.

B.The umbrella was first invented to be used as protection against the sun instead of rain.

C.The umbrella changed much in style and became lighter in weight in the 18th century.

D.In Europe, the Greeks were the first to use the umbrella as a kind of modern fashion.

4.This passage mainly talks about ________.

Chinese people love the peach blossom. Many people write poems about it. People usually compare(比作) the peach blossoms to beautiful young women. A famous sentence goes as, “In this house on this day last year a pink face vied; In beauty with the pink peach blossom side by side.” The peach blossom is like the flush on a shy woman’s face.
