【题目】下列事实能证明自然界海陆变迁的是

A.太行山发现海洋生物化石B.香港填海造陆

C.潮涨潮落引起海岛面积变化D.春夏秋冬四季变化

【答案】A

【解析】

在地球表面某位置发生的由海变为陆或由陆变为海的变化叫做海陆变迁,海陆变迁即洋陆转化。按运动方向可分为水平运动和垂直运动。水平运动指组成地壳的岩层,沿平行于地球表面方向的运动。也称为造山运动或褶皱运动。该种运动常常可以形成巨大的褶皱山系,垂直运动,又称为升降运动、造陆运动,它使岩层表现为隆起和相邻区的下降,可形成高原、断块山及拗陷、盆地和平原,还可引起海侵和海退,使海陆变迁。

太行山发现海洋生物化石,说明太行山在很久以前是海洋,能够证明自然界海陆变迁,故A正确;香港的填海造陆是人类活动造成的海陆变迁,故B错误;潮涨潮落引起海岛面积的变化是潮汐现象,不能证明海陆变迁,故C错误;春夏秋冬的四季变化是地球的公转运动造成的,故D错误。故选:A

【题目】I was in line waiting to pay. In line there were two people before me. A little boy was buying some rather strange clothes. He chatted with anyone who was interested in the clothes and soon we learnt that he was going to a kindergarten(幼儿园) party. He had done a great job of putting together interesting costumes.

I noticed that the little boy was paying mostly with change(零钱). It seemed that he had robbed his pig bank(猪形储蓄罐) to do this shopping. However, the cashier told him he was short after counting all the money. The boy thought for a moment and said, “Please keep the shirt and I will come back with more money. “

It was clear that he had already used all the money he had and he was $ 8.00 short. The lady in front of me said, “Well, I could pay half of that. “I told the boy that I could pay the other half. We dug into our handbags. However, both of us only had ten-dollar bills(纸币) and we needed the cashier to get the change for us. Other shoppers began digging into their pockets to find some change. It was amazing and touching as all these strangers seemed to react(反应) with the same mind. All wanted to be of help. Within minutes the cashier said, “I have too much money.” The cashier didn’t need our ten-dollar bills. Then the lady in front of me, who had been the first to offer help, said, “Wait! I didn’t even get a chance to give anything!”

I smiled at her and said, “You did your share, because it was your idea and you started all this. “ The little boy smiled and thanked us. We wished him the best and he left. I was left with a good feeling. I had seen the love and goodness of others all around me. The woman in front of me smiled and said, “It sure feels good to give, doesn’t it?” I smiled back and said, “Yes !”
