That’s right, animals. Scientists have begun to understand what farmers have known for thousands of years. Animals often seem to know in advance that an earthquake is coming, and they show their fear by acting in strange ways. Before a Chinese quake in 1975, snakes awoke from their winter sleep early only to freeze to death in the cold air. Cows broke their halters (缰绳) and tried to escape. Chickens refused to enter their cage. All of this unusual behavior, as well as physical changes in the earth, warned Chinese scientists of the coming quake. They moved people away from the danger zone and saved thousands of lives.
One task for scientists today is to learn exactly which types of animal behavior predict quakes. It’s not an easy job. First of all not every animal reacts to the danger of an earthquake. Just before a California quake in 1977, for example, an Arabian horse became very nervous and tried to break out of his enclosure. The Australian horse next to him, however, remained perfectly calm. It’s also difficult at times to tell the difference between normal animal restlessness and “earthquake nerves”. A zoo keeper once called earthquake researchers to say that his cougar had been acting strangely. It turned out that the cat had an upset stomach.
A second task for scientists is to find out exactly what kind of warnings the animals receive. They know that animals sense far more of the world than humans do. Many animals can see, hear, and smell things that people do not even notice. Some can sense tiny changes in air pressure, gravity, or the magnetism of Earth. This extra sense probably helps animals predict quakes.
A good example of this occurred with a group of dogs. They were shut in an area that was being shaken by a series of tiny earthquakes. (Several small quakes often come before or after a large one.) Before each quake a low booming sound was heard. Each boom caused the dogs to bark wildly. Then the dogs began to bark during a silent period. A scientist who was recording quakes looked at his machine. It was acting as though there were a loud noise too. The scientist realized that the dogs had reacted to a booming noise. They also sensed the tiny quake that followed it. The machine recorded both, though humans felt and heard nothing.
In this case there was a machine to monitor what the dogs were sensing. Many times, however, our machines record nothing extraordinary, even though animals know a quake is coming. The animals might be sensing something we measure but do not recognize as a warning. Discovering what animals sense, and learning how they know it is a danger signal, is a job for future scientists.

Baseball is the most popular sport in the US. It is played throughout the spring and summer, and professional baseball teams play well into the fall.
Football is the most popular sport in the fall. The game originated as a college sport more than 75 years ago. It’s not the same as European football or soccer. In American football there are 11 players as well on each team, and they are dressed in padded uniforms and helmets because the game is rough and injuries are likely to occur. It is still played by almost every college and university in the country.
Basketball is the winner sport in American schools and colleges. Like football, basketball originated in the US, many Americans prefer it to football because it is played indoors throughout the winter and because it is a faster game. And the famous NBA games are considered the best of this game.
Other sports attracting a great many people include wrestling, boxing and horse racing. Although horse-racing fans call themselves sportsmen, the exactness of the term is questionable, as only the jockeys who ride the horses in the races can be considered athletes. The so-called sportsmen are the spectators, who do not come primarily to see the horses race, but to bet upon the outcome of each race. Gambling is the attraction of horse racing.

Around 2 pm every Thanksgiving Day, family members seat themselves around the kitchen table. Plates of turkey, vegetables, salad, rolls and pies cover it. At this point, we can hardly keep ourselves from drooling (流口水) all over our fancy clothes, but it’s not yet time to eat.
First, we must bow our heads, close our eyes and say a prayer of thanks aloud to God for giving us everything we have. Under normal circumstances, I would have no problem making a list of things I am thankful for. I grew up in a loving family. My parents, who aren’t wealthy, took out loans to help me pay for university.
But, the funny thing is, every time I sit down for Thanksgiving dinner and try to say a prayer of thanks, my mind usually goes blank. I think it has something to do with my growling (咕咕叫) stomach and all of that food sitting right there under my nose.
Eventually, though, we all finish our short prayers and dig in. To be sure, the day includes other highlights – visiting with family and watching football. But usually around 6 pm we are all ourselves stuffed like turkeys and thankful to have a nice warm bed to sleep in.
小题1:The purpose of the text is to ________.
A.tell what the family do for Thanksgiving Day |
B.tell how the family spends Thanksgiving Day |
C.introduce foods served on Thanksgiving Day |
D.introduce the American Thanksgiving Day |

C.having a big meal | D.watching football |
A.He is too thankful to say a word. |
B.His mind is on the food before him. |
C.He feels too excited to speak. |
D.He is shy to speak in public. |
A.chat with others | B.make a hole |
C.mix things up | D.start eating |
A.On Thanksgiving Day, men do nothing but eat. |
B.The author is a middle school student. |
C.The author’s family is not rich, but it’s a loving one. |
D.Thanksgiving Day falls on Thursday of December. |
White has a clean and pure image. That is why doctors, dentists, and nurses usually wear white uniforms. Babies are dressed in white at baptisms(洗礼)and brides wear white wedding gowns at weddings. White in these cases is the symbol of innocence or purity.
Sometimes white is used in expressions that are not good. “Whitewash” is one such expression. At first, “whitewash” meant to paint over something with white paint to make it look better. However, it means something different today: to hide or to cover up mistakes or failures.
A “white elephant” is another example of white used in a negative way. In ancient Thailand, a white elephant was regarded as a sacred animal, but it was very expensive to keep. The kings of those days presented a white elephant to the people they wanted to ruin. Once they received this holy, royal animal as a gift, they were not allowed to sell or kill it. Today, a “white elephant” means something that is big, useless, and unwanted. In America, when people want to get rid of their furniture or clothes, they often have a “white elephant sale”.

We know that you have a high opinion of the kind of learning taught in your colleges, and that the costs of living of our young men, while with you, would be very expensive to you. We are sure that you mean to do us good by your proposal(提议); and we thank you heartily. But you must know that different nations have different ways of looking at things, and you will therefore not be offended(冒犯) if our ideas of this kind of education happen not to be the same as yours. We have had some experience of it. Several of our young people were formerly brought up at the colleges of the northern provinces: they were taught all your sciences; but when they came back to us, they were bad manners, ignorant(无知的)of every means of living in the woods–they were totally good for nothing.
We are, however, not the less thankful by your kind offer, though we refuse to accept it; and, to show our grateful sense of it, if the gentlemen of Virginia will send us a dozen of their sons, we will take care of their education, teach them in all we know, and make men of them.
