【题目】下列关于海陆分布的说法正确的是( )

A. 七分海洋,三分陆地B. 北极地区以陆地为主

C. 南极地区以海洋为主D. 陆地主要集中在南半球

【答案】A

【解析】

根据我们生活的地球,从太空看是个蔚蓝色的美丽星球,它看上去更像“水球”.根据人们的计算,地球上陆地面积占29%,海洋面积71%;陆地集中于北半球、东半球;海洋集中于南半球、西半球。将地球分为水半球和陆半球,陆半球上依然是海洋多于陆地。所以,无论怎样划分半球,都是海洋多于陆地,进行分析解答。

根据人们的计算,地球上陆地面积占29%,海洋面积71%,概括地说,地球上七分是海洋,三分是陆地;陆地集中于北半球、东半球;海洋集中于南半球、西半球;北极地区为海洋,南极地区为陆地,A对,BCD错。故选:A。

【题目】I didn’t make much money when I took the job in London. I always had simple meals.

One night, I felt very tired, so I sat outside in a small park and began to eat a small piece of bread.

A tall man who was not dressed well walked to me. He thought I had money and asked, “Sir, could you please give me some money?”

I said, “I don’t have any.”

He said, “I know the persons like you wouldn’t give anybody anything.”

I became very angry because he didn’t believe me. I looked at him and gave my wallet to him, “Look in my wallet.”

He then said “sorry” to me and opened his wallet and said, “Here I will give you some.”

I looked at him in surprise and said, “No, thank you.” And then I walked away.

Money is important, but I’d rather(宁愿) make it by working hard than get by asking others for it.

根据短文内容,判断正误,正确的填“T”。错误的填“F”

1The writer(作者) had a small piece of bread for lunch in a restaurant.

2At first, the tall man asked the writer for some money.

3The writer was angry with the tall man because the tall man didn’t believe him.

4There was much money in the writer’s wallet.

5Finally, the writer got some money from the tall man.
