【題目】下列關于海陸分布的說法正確的是( )

A. 七分海洋,三分陸地B. 北極地區(qū)以陸地為主

C. 南極地區(qū)以海洋為主D. 陸地主要集中在南半球

【答案】A

【解析】

根據(jù)我們生活的地球,從太空看是個蔚藍色的美麗星球,它看上去更像“水球”.根據(jù)人們的計算,地球上陸地面積占29%,海洋面積71%;陸地集中于北半球、東半球;海洋集中于南半球、西半球。將地球分為水半球和陸半球,陸半球上依然是海洋多于陸地。所以,無論怎樣劃分半球,都是海洋多于陸地,進行分析解答。

根據(jù)人們的計算,地球上陸地面積占29%,海洋面積71%,概括地說,地球上七分是海洋,三分是陸地;陸地集中于北半球、東半球;海洋集中于南半球、西半球;北極地區(qū)為海洋,南極地區(qū)為陸地,A對,BCD錯。故選:A。

【題目】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(寧愿) make it by working hard than get by asking others for it.

根據(jù)短文內容,判斷正誤,正確的填“T”。錯誤的填“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.
