The notice in the paper said that you could buy tickets at the theater box office any day between 10:30 a.m and 3:00 p.m. The only time I could go to the theater was during my 45-minute lunch break. Unluckily , the theater is on the other side of the town, and the bus service is not very good. But if you are lucky, you can make the round trip in 45 minutes.Last Monday, I stood at the bus stop for fifteen minutes waiting for the bus. By the time I sawone come around the corner, there was not enough time left to make the trip. So I gave up and went back to the office. The same thing happened on Tuesday, and again Wednesday. On Thursday , my luck changed .I got on a bus right away. When I got there, however, I found a long line of people at the box office. I had to catch the next bus and went back across the town .By Friday I decided to make the trip by taxi, it was expensive, but I felt the concert would be worth hearing. The trip by taxi only took 10 minutes, but it felt like an hour to me. When I got to the theater, I was relieved to see that nobody was waiting in line. The reason , I quickly found, was that they had already sold out all the tickets.31.The writer learned ___that there would be a concert last Friday.A. from his friendsB. from one of his workmatesC. over the radioD. from the newspaper32.The writer tried to go to the theater every day but successfully got there only_____A. twiceB. three timesC. four timesD.five times33.If lucky, the writer could spend about ____on the trip to the theater from his office by bus.A. forty-five minutesB. twenty minutesC. ten minutesD.fifteen minutes34.Maybe the word”____”can be used instead of the word “relieved”A. nervousB. gratefulC. pleasedD. sorry35.The writer mainly tells us he ______.A. enjoyed himself in the theaterB. was angry at buying the ticketC. had some trouble with the bus serviceD. was sad at missing the concert(B)Switzerland is famous for its watches. but this country didn’t invent the watch. It was the British who did .Here is a story of how the watch was brought to Switzerland.Many years ago, an Englishman travelled to Italy. This English man travelled in a carriage. On his way, he stopped in a small town called Geneva in Switzerland.There was a carriage clock in it. This was the earliest kind of watch .A blacksmith’s assistant happened to see the clock. He wanted to know what it was and asked the Englishman about it.”It is a carriage clock,” said the man.”This machine can tell the time but it isn’t working now.”The blacksmith’s assistant wanted to try to repair it, so the traveler handed him the clock .The assistant was a very clever man, so it was easy for him to repair it.He even remembered how it was made. As soon as the traveler had gone on his way, he made a watch of exactly the same type.So the watch-making was started in Switzerland. Today, Swiss watches are sold in countries all over the world.36.What is Switzerland famous for?_______A. TVsB. PensC. WatchesD.

Sea lions don’t need to drink water----they get all the water they need from the food they eat. They eat fish and some small animals in the sea. Sea lions must breathe air and they can’t stay under water forever! Sea lions are divers. When they dive, a sea lion can stay under water for about 40 minutes at a time .Sea lions are great swimmers,too. Its speed can reach 40 kilometers an hour .This helps them escape from their enemies: killer whales and sharks .But they can’t escape from human beings! Each year a lot of sea lions die painfully .Thousands of sea lions were killed for their skin and oil. That’s too bad. We must protect them from disappearing in the world or our grandchildren may have no chance to see them any more.41.Where do sea lions live?A. On landB. In the riverC. In the lakeD.

For example, there are few earthquakes in Britain.There is often a great noise during an earthquake .The ground shakes and houses fall down. Railway lines are broken. Trains run off the railroad .Sometimes thousands of people are killed in different ways. In 1783,about 60,000 people were killed in South Italy and another big earthquake in 1883 killed 35,000 people in Indonesia.Fires often follow earthquakes. The Tokyo earthquake of 1923 took place just before the middle of the day. People were cooking meals on their fires at that time. When the ground shook, the fires shook, too. Burning things were thrown on to different parts of the wooden houses. Soon fires were burning in the city.Another big earthquake happened in India in 1896.The ground suddenly moved 0.45m toone side. Then is moved back again. It moved like this 200 times a minute. Nearly all the buildings and trees fell down a few minutes later.46._____has few earthquakes.A. IndiaB. ItalyC. JapanD.

To begin with, I like the idea of dreaming, of going to bed and lying still and then, by some queer magic , wandering into another kind of existence. As a child , I could never understand why grown-ups took dreaming so calmly when they could make such a fuss(大惊小怪) about any holiday. This still puzzles me. I am puzzled by people who say they never dream and appear to have no interest in the subject. It is much more astonishing than it would be if they said they never went out for a walk. Most people do not seem to accept dreaming as part of their lives. They appear to see it as an irritating (令人困扰的) little habit, like sneezing or yawning (打嗝).I can never understand this .My dream life does not seem as important as my waking life because there is far less of it, but to me it is important.51.What is the author’s attitude toward dreaming ?A.
