【题目】某国2014年初共有人口500万人,该年内出生并成活婴儿4.85万人,死亡人95.2万人。据此回答下列各题。

C. 环境恶化,住房紧张 D. 劳动力过剩

【答案】

1 B

2 B

【解析】

人口增长率是由人口出生率减去人口死亡率,人口的增长不仅取决于人口出生率,还取决于人口死亡率。

1由题目可知,该国的人口出生率是9.7‰,死亡率是10.4‰,所以人口自然增长率是由9.7‰-10.4‰=-0.7‰,故选B。

2由上题可知,该国人口出生率出现了负数,说明该国人口出现了负增长,这样会使该国面临人口老龄化的问题,故选B。

【题目】Betty and I are best friends. Our birthdays are on the same day, so every year we have a birthday party together. But this year, we had a costume party(化装晚会) instead.

While we were writing the invitations, my mum came in and asked, “Why not invite John?” John had been in our class for only a few months, but he was already getting better grades in math than anyone else in class. I wrinkled(皱起) my nose, “Mum, he wears the same pants to school every day. How could he even afford a costume?” Mum said nothing. The next day, mum gave me an envelope with a shopping certificate(凭证) in it.” I thought it would be nice for you to give this to John.” Mum said. But how? We didn't want to make John embarrassed. We discussed it for a long time. Finally, Betty and I had a good idea.

On the day of our party, kids arrived, dressed differently. John arrived, in an old sheet (床单), but still in the same brown pants as usual. We danced, ate snacks and played games in groups. Before eating the birthday cake, Betty said in a loud voice, “Now it is time for the great prize game. It is the following riddle(谜语) …” It was a math game. None of us was surprised when John came up with the right answer first and walked off with the envelope.

Everything went on well as we planned. John wore a new pair of pants and a new shirt the next week. He felt happy. So did we.
