听力原文：My wife and I accidentally go to a nice restaurant to eat. My wife's mother lives

听力原文： My wife and I accidentally go to a nice restaurant to eat. My wife's mother lives with us and she stays with the children. This makes it very easy for us to go out for the evening.

Last week we went to the restaurant in a new hotel. We had a wonderful meal. First, we had soup. Then Helen, my wife, had beef with carrots, and I had beef with potatoes. For dessert, I had some ice cream and Helen had fresh fruit. We had several cups of coffee after we finished eating. The food was delicious, the quantity was large, and it wasn't too expensive.

Our children don't like to eat in restaurants because they have to sit and be quiet for a long time. They would rather go to their grandmother's farm. Their grandmother -- my mother prepares everything they like. She usually has fried chicken, corn, and hot biscuits with honey. She always serves plenty of chocolate ice cream and cake for dessert.

I'm always surprised that my father doesn't weigh a lot more when I see how much he eats. But he works very hard on the farm from about 5 o'clock in the morning until it gets dark in the evening.

When my parents visit us in the city, we usually take them to a restaurant; I know they enjoy it, but my father always eats something else after he gets home. The quantity may be large in the restaurant, but it is still not large enough for a hungry farmer.

Who stays with the children when the speaker goes out？

A．His mother.

B．His wife's mother.

C．The servant.

听力原文：Email captures the essence of life at the close of the 20th century with an autho

rity that few other products of digital technology can claim. Email, ultimately, is a fragile thing, easy to forge, easy to corrupt, easy to destroy. A few weeks ago, a co-worker of mine accidentally and irretrievably wiped out 1,500 of his own saved messages. For a person who conducts most of his life online, such a digital tragedy is akin to erasing part of his own memory. Suddenly, nothing is left. He has lost himself as well as his links with others.

Which of the following is true, according to the passage？

A．Email shows more authority than other products of digital technology.

B．Email is as fragile a thing as it is convenient to its users.

C．Email can keep as many as 1,500 saved messages.

D．Email may help strengthen your own memory.

听力原文： The first man who cooked his food, instead of eating it raw, lived so long ago t

hat we have no idea who he was or where he lived. We do know, however, that for thousands of years, food was eaten cold and raw. Perhaps the first cooked food was heated accidentally by a forest fire or by the molten lava from an erupting volcano. No doubt, when people first tasted cooked food, they found it tasted better. However, even after this discovery, cooked food must have remained a rarity until man learned how to make and control fire.

Early people who lived in hot regions could depend on the heat of the sun to cook food. For example, in the desert areas of the southwestern United States, the Indians cooked their food by placing it on a flat stone in the hot sun. They cooked pieces of meat and thin cakes of corn meal in this fashion.

We can assume that the earlier kitchen utensil was a stick to which a piece of meat could be attached and held over a fire. Later this stick was replaced by an iron rod which could be turned frequently to cook the meat on all sides. Cooking food in water was impossible before man learned to make water containers that could not be destroyed by fire.

All of man' s history has been shaped by his search for food. Man' s first occupation was of that of a hunter, and his first stone weapons were made for hunting. Then man learned to grow plants for food.

They began to settle in communities next to their fields. More people lived in the places where food was more available. Progress has been greater in these parts of the world where there is more food to eat.

In which way may the first cooked food be made？

A．It was accidentally baked on volcanoes.

B．It was cooked by forest fire by chance.

C．It was boiled in the natural hot-water spring.

D．It was cooked by the heat of the sun.

阅读文章，回答下列各题： When people print a stamp, any error made on a stamp raises its val

ue to stamp collectors. A mistake on one inexpensive postage stamp has made the stamp worth a million and a half times its original value. More than one hundred years ago in the British colony of Mauritius, a small island in the Indian Ocean, the mistake was made. In 1847 an order for stamps .was sent to a London printer -- Mauritius was to become the fourth country in the world to issue stamps. Before the order was filled and delivered, a bail was planned at Mauritius' s Government House, and stamps were needed to send out the invitations. A locai printer was instructed to copy the design for the stamps. He accidentally inscribed the words "Post Office" instead of "Post Paid" on the severai hundred stamps that he printed. Today there are only twenty-six of these misprinted stamps left-fourteen One Penny Orange - Reds and twelve Two Penny Blues. Because of the Two Penny Blues' rareness and age, collectors have paid as much as $16,800 for it. Over a century ago, Mauritius__________

A. was an independent country

B. was a smail island in the Pacific Ocean
