下图为“1月某日欧洲西部部分地区海平面等压线分布图（单位：hap）”。读图完成下列各题。
图中气压差值最大可能达到（）
A、23hap
B、20hap
C、21hap
D、11hap
参考答案：A
解析：图中等压线的等值距为4hap，图示区域最高等压线闭合区域数值为1024hap，根据气压的变化趋势，闭合区域内气压应该在1024～1028hap之间。图示区域最低气压在1008～1004hap之间。图示范围气压差值介于16～24hap之间，所以图中气压差值最大可能达到23hap。故选A。

| One evening I was parked in front of the mall, wiping off my car. 1 my way from across the car park, was what people would consider a bum(流浪汉). From the looks of him, could see he had almost 2 . Sometimes you feel generous, but there are times that you just don't want to be 3 . "Hope he doesn't ask me for money," I thought. He didn't. He sat down nearby and 4 my car.

Something inside urged me, "Ask him 8 he needs any help." "Do you need any help?" I asked. "Don't we all?" he replied. It 9 me! These were three simple but most shocking words I had ever heard. I usually 10 wisdom from those of high learning and achievements. I expected nothing here but an 11 dirty hand. I need help. Maybe not for bus fare or a place to sleep, 12 I need help. However much you have, however much you have 13 , we all need help. No matter how 14 you have, no matter how loaded you are with problems, you can 15 help, even if it's just a pleasant remark. You never know when you may see someone that 16 to have it all, yet 17 , they need you to give them what they don't have. Maybe the man was just a 18 stranger going about the streets. Maybe he was 19 that. Maybe he was an angel 20 like a bum and was ordered, "Go to that man cleaning the car; that man needs help." Don't we all? | ||||
