【題目】下列事實能證明自然界海陸變遷的是

A.太行山發(fā)現(xiàn)海洋生物化石B.香港填海造陸

C.潮漲潮落引起海島面積變化D.春夏秋冬四季變化

【答案】A

【解析】

在地球表面某位置發(fā)生的由海變?yōu)殛懟蛴申懽優(yōu)楹５淖兓凶龊ｊ懽冞w，海陸變遷即洋陸轉(zhuǎn)化。按運動方向可分為水平運動和垂直運動。水平運動指組成地殼的巖層，沿平行于地球表面方向的運動。也稱為造山運動或褶皺運動。該種運動常�？梢孕纬删薮蟮鸟薨櫳较�，垂直運動，又稱為升降運動、造陸運動，它使巖層表現(xiàn)為隆起和相鄰區(qū)的下降，可形成高原、斷塊山及拗陷、盆地和平原，還可引起海侵和海退，使海陸變遷。

太行山發(fā)現(xiàn)海洋生物化石，說明太行山在很久以前是海洋，能夠證明自然界海陸變遷，故A正確；香港的填海造陸是人類活動造成的海陸變遷，故B錯誤；潮漲潮落引起海島面積的變化是潮汐現(xiàn)象，不能證明海陸變遷，故C錯誤；春夏秋冬的四季變化是地球的公轉(zhuǎn)運動造成的，故D錯誤。故選：A。

【題目】閱讀下列材料，回答問題。

材料一 我國是世界上水土流失最嚴(yán)重的國家之一，水土流失面積超過180萬平方米，約占全國陸地面積的1/5。每年流失表土在50億噸以上，流失的土壤養(yǎng)分相當(dāng)于全國一年的化肥產(chǎn)量。

材料二 新中國成立以來，我國耕地逐年減少，耕地流失嚴(yán)重。據(jù)調(diào)查統(tǒng)計，1980～1999年的20年間，我國擠占挪用及損毀的耕地超過600萬公頃，平均每年流失耕地超過30萬公頃。耕地減少加劇了我國人口與耕地的供需矛盾。

材料三 我國土地荒漠化正以每年1000～2000平方千米的速度蔓延。因過度開墾，過度放牧引起的草原退化、土地沙化面積有160多萬平方千米。風(fēng)消蔓延導(dǎo)致許多地方的牧場、良田和村莊被毀、埋沒。

【題目】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(幼兒園) party. He had done a great job of putting together interesting costumes.

I noticed that the little boy was paying mostly with change(零錢). It seemed that he had robbed his pig bank(豬形儲蓄罐) 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(紙幣) 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(反應(yīng)) 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 !”

【1】What is this passage mainly about?

A. Love and goodness. B. Culture and tradition.

C. Friendship and honesty. D. Communication and understanding.

【2】Why did the writer and the woman both feel glad?

A. Because the boy had saved some money.

B. Because they both didn’t need to give anything.

C. Because the cashier didn’t look down on the boy.

D. Because all the shoppers around were willing to help the boy.

【3】What’s the correct order of the following events?

a. The cashier got enough money for the boy’s shirt.

b. The cashier counted the boy’s money.

c. The shoppers looked for some change in their pockets.

d. The boy went to the line to pay.
