答案

小题1:D

小题2:C

小题3:B

小题4:C

小题1:本题考查地球公转的概况。地球公转的方向为自西向东,从北极上空看为逆时针;公转周期为恒星年,为365日6时9分;公转到近日点1月初附近时地球公转速度最快。所以本题选择D选项。

小题2:春分日(3月21日前后)、秋分日(9月23日前后)太阳直射赤道,夏至日(6月22日前后)太阳直射北回归线,冬至日(12月22日前后)太阳直射南回归线。元旦直射点位于南半球,并向北移动。所以本题选择C选项。

小题3:从天文现象上看,地球上的季节变化是昼夜长短和太阳高度的季节变化。所以本题选择B选项。

小题4:在纬度相同的地方,白昼时间相同,则日出时间相同。所以本题选择C选项。

     One man was reading a newspaper on the deck of a ship.Suddenly it blew strongly, the man's hat

was blown into the sea. He touched his head with his hand and went on reading his newspaper.

     There was a person beside him who was surprised and told him: "Sir. Your hat was blown into the

sea. "  "I see. Thanks. " He said and then read the newspaper again.    "But your hat is  worth a lot of

money. "  "Yes,  I am thinking of how to save money and buy another one.  I lost my hat,  I felt very

sorry. But can it come back?"

     It is true that the lost thing  sometimes  will never return.  It is better to think of ways to solve the

problem than trying to find it.

Then they would feel very sorry and bitter.  Why? It is because they can't adjust(调整) our attitude

(态度) to such things. And only think about the things which will never return. But I think we should

think about how to get the new one instead of regretting(遗憾) only.

判断正误,对的用(A),错误的用(B)。
