Byrd, successfully flew over the South Pole for the first time. Though, at first, Byrd and his men were able to take a great many photographs of the mountains that lay below, they soon ran into serious trouble. At one point, it seemed certain that their plane would crash. It could only get over the mountains if it rose to 10,000 feet. Byrd at once ordered his men to throw out two heavy food sacks. The plane was then able to rise and it cleared the mountains by 400 feet. Byrd now knew that he would be able to reach the South Pole which was 300 miles away, for there were no more mountains in sight. The aircraft was able to fly over the endless white plains without difficulty. slowly. It obviously could not tell the difference between Indian music and jazz!t have too many hats,39。A woman in blue jeans stood at the window of an expensive shop. Though she hesitated for a moment, she finally went in and asked to see a dress that was in the window. The assistant who served her did not like the way she was dressed. Glancing at her scornfully, he told her that the dress was sold. The woman walked out of the shop angrily and decided to punish the assistant next day. She returned to the shop the following morning dressed in a fur coat, with a handbag in one hand and a long umbrella in the other. After seeking out the rude assistant she asked for the same dress. Not realizing who she was, the assistant was eager to serve her this time with great difficulty, he climbed into the shop window to get the dress. As soon as she saw it, the woman said s many ties.39。Once a year a race is held for old cars. A lot of cars entered for this race last year and there was a great deal of excitement just before it began. One of the most handsome cars was a RollsRoyce Silver Ghost. The most unusual car was a Benz which had only three wheels. Built in 1885, it was the oldest car taking part. After a great many loud explosions, the race began. Many of the cars broke down on the course and some drivers spent more time under their cars than in them ! A few cars, however, pleted the race. The winning car reached a speed of forty miles an hourmuch faster than any of its rivals. It sped downhill at the end of the race and its driver had a lot of trouble trying to stop it. The race gave everyone a great deal of pleasure. It was very different from modern car races but no less exciting. may reveal something of value fairly soon. I find it beautiful,39。 my wife answered.39。 I remarked suddenly. I regretted saying it almost at once.39。 I said to my wife. 39。 she answered,39。 Will you be staying in England?39。 I asked. 39。 39。39。 s operation had been successful and the doctor told him that it had been. He then asked when Mr Gilbert would be allowed to go home and the doctor told him that he would have to stay in hospital for another two weeks. Then Dr Millington asked the caller if he was a relative of the patient.39。Lesson39 Am I all right? 我是否痊愈?Lesson38 Everything except the weather 惟獨(dú)沒有考慮到天氣Olympic City39。Lesson37 The Olympic Games 奧林匹克運(yùn)動(dòng)會(huì)s school friends will be waiting for her on the English coast.
