Choose the best answer.（根据短文内容，选择最恰当的答案）（1）For a while, my neighborhood was taken over by an army of joggers. They were there all the time: early morning, noon, and evening. There were little old ladies in gray sweats, young couples in Adidas shoes, middle-aged men with red faces. “Come on!” My friend Alex encouraged me to join him as he jogged by my house every evening. “You’ll feel great.”Well, I had nothing against feeling great and if Alex could jog every day, anyone could. So I took up jogging seriously and gave it a good two months of my life, and not a day more. Based on my experience, jogging is the most overvalued form of exercise around, and judging from the number of the people who left our neighborhood jogging army. I’m not alone in my opinion.First of all, jogging is very hard on the body. Your legs and feet a real pounding (重击) running down a road for two or three miles. I developed foot, leg, and back problems. Then I read about a nationally famous jogger who died of a heart attack while jogging, and I had something else to worry about. Jogging doesn’t kill hundreds of people, but if you have any physical weaknesses, jogging will surely bring them out, as they did with me.Secondly, I got no enjoyment out of jogging. Putting one foot in front of the other for forty-five minutes isn’t my idea of fun. Jogging is also a lonely pastime. Some joggers say, “I love being out there with just my thoughts.” Well, my thoughts began to bore me, and most of them were on how much my legs hurt.And how could I enjoy something that brought me pain? And that wasn’t just the first week: it was practically every day for two months. I never got past the pain level, and pain isn’t fun. What a cruel way to do it! So many other exercises, including walking, lead to almost the same results painlessly, so why jog?I don’t jog any more, and I don’t think I ever will. I’m walking two miles three times a week ata fast pace, and that feels good. I bicycle to work when the weather is good. I’m getting exercise,and I’m enjoying it at the same time. I could never say the same for jogging, and I’ve found a lot of better ways to stay in shape.68. From the first paragraph, we learn that in the writer’s neighborhood _____.A. jogging became very popularB. people jogged only during the daytimeC. Alex organized an army of joggersD. jogging provided a chance to get together69. The underlined word “them”(Paragraph 3) most probably refers to ____.A. heart attacksB. Back problemsC. famous joggersD. physical weaknesses70. What was the writer’s attitude towards jogging in the beginning?A. He felt it was worth a try.B. He was very fond of it.C. He was strongly against it.D. He thought it must be painful.71. Why did the writer give up jogging two months later?A. He disliked doing exercise outside.B. He found it neither healthy nor interesting.C. He was afraid of having a heart attack.D. He was worried about being left alone.72. From the writer’s experience, we can conclude that _____.A. jogging makes people feel greater than any other sportB. he is the only person who hates joggingC. nothing other than jogging can help people keep fitD. not everyone enjoys jogging（2）When the great library of Alexandria burned, the story goes, one book was saved. But it was not a valuable book; and a poor man bought it for very little money.The book wasn't very interesting, but between its pages there was something very interesting indeed. It was a thin strip of animal skin on which was written the secret of the "Touchstone（试金石）"! The touchstone was a small pebble that could turn any common metal into pure gold.The writing explained that it was lying among thousands and thousands of other pebbles that looked exactly like it. But the secret was this: The real stone would feel warm, while ordinary pebbles are cold.So the man sold his few belongings, bought some simple supplies, camped on the seashore, and began testing pebbles. He knew that if he picked up ordinary pebbles and threw them down again because they were cold, he might pick up the same pebble hundreds of times. So, when he felt one that was cold, he threw it into the sea. He spent a whole day doing this but none of them was the touchstone. Yet he went on and on this way. Pick up a pebble. Cold - throw it into the sea. Pick up another. Throw it into the sea. Pick up another. Throw it into the sea.
