Coffee containsa kind of drug called caffeine (咖啡因).Caffeine can stimulate (刺激) the nerves of the body. Drinking coffee tends to make peoplea little bit more awake. One story of thediscovery of the coffee plant in East Africa records this effect of caffeine. The story says that coffee was first found by a goat farmer named Kaldi about the year 850.Kaldi was leading his animals through the mountains and the goats were stoppingrepeatedly to eat the plants near the path.Suddenly, some of the goats started jumping up and down in a very strange way.Kaldi figured out that the goats were acting this way because of the plants they were eating. Kaldi himself tried eating some of the green beans that the goats had been10eating. He, too, felt the same effect of the beans.Kaldi wanted to prove what had happened, so he picked some of the beans and took them back to his home village. The green bean got the name“Kaffa”and later“coffee” because the beans were discovered in a place called Kaffa in Africa.Then for years, people used to eat a few of the green Kaffa beans when they were in the mountains and needed extra energy. It was later found that the coffee beans could be picked and then dried until they turned brown, and then they could be stored. Then they could be used at any time.54.What is caffeine?A) A kind of bean. B) A kind of plant.C) A kind of coffee. D) A kind of drug.55.What is the purpose of drinking coffee?A) To become stranger.B) To become cleverer.C) To become more healthy.D) To become more awake.56.Coffee was first found by a _______.A) goat B) chemist C) doctor D) farmer57.How did the goats react after eating the plants?A) They became awake.

If so, then you have seen those beautiful bright points that light up the sky. Many, many stars can be seen at night. Long ago, people wondered about the stars. They watched them closely each night. After a long time they began to see that the points made pictures. One of these looked like a bear. Some looked like other animals. Still others looked like people. After seeing these pictures over and over again, people gave them names. One picture that was named long ago is called the Big Dipper. It is made up of seven stars. These stars make a picture of a cup on a long stick, or handle. This cup and handle is called a dipper. A dipper is used to hold water. People can drink right from it. Or they can put the water into a glass first. It is hard to see the Big Dipper in the winter when it is low in the sky. Then tall buildings or big hills can get in the way. They can hide it. But it can be seen better in summer. Face north and look high in the sky. There it is! Look to the right of the Big Dipper. You will see a special star. This is the North Star. It always shows where north is. So people long ago used it to find their places. You too can use it to find where you want to go.59.Why did people long ago call the seven stars the Big Dipper?A) Because people in the past gave all stars names.B) Because these stars form a picture of a cup with a handle.C) Because the Big Dipper is a good name.D) Because these seven stars form a cup.60.Which of the following is NOT true about the North Star?A) The Big Dipper is to the left of the North Star.B) The North Star is one star of the Big Dipper.C) The North Star always shows where north is.D) The North Star helps people to find their places. 61.Which of the following is NOT true aboutthe descriptions of the pictures made by thestars in the sky?A) Some pictures look like plants.B) All pictures look like people.C) All pictures look like instruments.D) Some pictures look like animals.62.When can the Big Dipper be seen better?A) In winter.

This was too much for any composer(作曲家) to bear. Beethoven became hopeless; he was sure that he was going to die. He went to the countryside where he wrote a long good-bye letter to his brothers, describing how sad and lonely his deafness made him. He longed to die, and said to death, “Come when you will; I shall meet you bravely.”In fact, Beethoven did something braver than dying. He gathered his courage and went on writing music, He wrote the music for which we remember him best after he became deaf. This music was very different from any that had been composed before. Instead of the past artistic music for the rich listeners, Beethoven wrote stormy, exciting music which reminds us of his troubled and courageous life. In time he went completely deaf, but he wrote more creatively than ever, for he could “hear” his music in his mind. .His Heroic Symphony(交响乐) and Fifth Symphony both showhis courage in struggling with his fate.In time he went completely deaf, but he wrote more creatively than ever, for he could “hear” his music in his mind. He was lonelyand often unhappy but in spite of this, heoften wrote joyful music, such as his last symphony, the Ninth. Because of his courageand strong will to success, his music has given joy and encouragement to millions of people.64.How did Beethoven’s deafness affect him?A) It helped him create good music.B) It drove him mad.C) It killed him.

You find a telephone number in the phone book, dial it and then forget it. This is your short-term memory. It lasts less than30 seconds. However you don’t look in the phone book for your best friend’s number. Y ou know it. This is a long-term memory. Your long-term memory has everything you remember. Why do you forget something?
