直径为8厘米的圆的面积与两个直径为4厘米的圆的面积之和相等．______．
直径为8厘米的圆的面积：3.14×（8÷2）2=50.24（平方厘米），
两个直径为4厘米的圆的面积之和：3.14×（4÷2）2×2=25.12（平方厘米），
50.24平方厘米＞25.12平方厘米，
所以“直径为8厘米的圆的面积与两个直径为4厘米的圆的面积之和相等”是错误的．
故答案为：×．

| A man was driving at 70 miles in a 40-mile zone, when a 1 came behind him. Right away the man started thinking of 2 to give. As the policeman came to him, he said, "Hi, officer, I guess you 3 me a little bit over the speed limit. I was in a rush to get 4 , to be with my wife and kids. You know my younger son wasn't feeling too 5 when I left home this morning. I'm afraid he's ill." The policeman said, "Well, I guess so," and started 6 something in his notebook. As minutes went by, he could see from the side view mirror, the police-man was 7 writing. When the man was wondering why he hadn't asked for his driving 8 so far, the policeman came to his window, 9 him a piece of paper, and returned to his car without saying a single word. The man wondered: how much was this 10 going to be? However, the man was 11 it was not a ticket at all and he began to 12 : "I had a daughter who was 13 by a speeding car at the age of six by a speeding driver. He got a fine, a few months in 14 , and then was free, free to hug his two daughters. I only had one, and now I have to 15 until I get to heaven before I can hug her again. I have tried to 16 that man a thousand times, and I thought I had. Maybe I really did forgive (原谅) him. So pray (祈祷) for me, and be 17 when you drive again. My son is all I have been left with." The man was completely 18 and could not move for the next few minutes. When finally he did, he drove 19 , even a few miles 20 the speed limit, praying for forgiveness. | ||||
