【題目】秦嶺一淮河一線是 ( )

A. 熱帶季風(fēng)氣候與亞熱帶季風(fēng)氣候的分界線

B. 400mm年等降水量線大致經(jīng)過(guò)的地方

C. 1月0℃等溫線大致經(jīng)過(guò)的地方

D. 半濕潤(rùn)地區(qū)與半干旱地區(qū)的分界線

【答案】C

【解析】

地理區(qū)域體現(xiàn)了區(qū)域內(nèi)部的地理相似性,地理界線反映出區(qū)域之間的地理差異性。秦嶺與淮河是我國(guó)東部重要的地理界線。在它的南北兩側(cè),自然環(huán)境、地理景觀和居民的生產(chǎn)生活習(xí)慣有顯著的差異。

秦嶺、淮河一線是我國(guó)四大區(qū)域中,南方地區(qū)與北方地區(qū)的分界線;一月份0℃等溫線通過(guò)的地方;800mm等降水量線通過(guò)的地方;溫度帶中,暖溫帶與亞熱帶分界線;干濕地區(qū)中,濕潤(rùn)區(qū)與半濕潤(rùn)區(qū)分界線;溫帶季風(fēng)氣候與亞熱帶季風(fēng)氣候分界線;農(nóng)業(yè)與畜牧業(yè)的分界線;耕地中水田和旱地的分界線等。故選C。

【題目】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
