B. 400mm年等降水量线大致经过的地方

C. 1月0℃等温线大致经过的地方

D. 半湿润地区与半干旱地区的分界线

【答案】C

【解析】

地理区域体现了区域内部的地理相似性,地理界线反映出区域之间的地理差异性。秦岭与淮河是我国东部重要的地理界线。在它的南北两侧,自然环境、地理景观和居民的生产生活习惯有显著的差异。

秦岭、淮河一线是我国四大区域中,南方地区与北方地区的分界线;一月份0℃等温线通过的地方;800mm等降水量线通过的地方;温度带中,暖温带与亚热带分界线;干湿地区中,湿润区与半湿润区分界线;温带季风气候与亚热带季风气候分界线;农业与畜牧业的分界线;耕地中水田和旱地的分界线等。故选C。

【题目】Dear Grandma,

How are you? Last Saturday I went to Long Bay with my parents. We got up at 6:00 a.m. We ate breakfast at 6:30 a.m. and after half an hour we left for Long Bay. My father is a good driver and he drove very fast. But I have to say, the trip was a bit long. When we got out of our car and got to Long Bay, it was already ten o’clock!

First we swam in the water for an hour. Then we played cricket (板球) for an hour. It was time to have lunch. We ate a big lunch in a restaurant. In the afternoon my mother and I enjoyed the sunshine on the beach. My father went fishing. He didn’t get any fish, but it was very relaxing. Soon it was time to go home. My parents and I left Long Bay. We had a great day last Saturday. My parents and I will go to see you this weekend. I miss you very much.

Yours,

Kate
