【題目】秦嶺——淮河一線大致同下列哪些界線-致( )

A. 1月00C等溫線B. 400毫米等降水量線

C. 熱帶與亞熱帶分界線D. 半濕潤(rùn)地區(qū)與半干旱地區(qū)分界線

【答案】A

【解析】

根據(jù)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,進(jìn)行分析解答。

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℃等溫線通過的地方;800mm等降水量線通過的地方;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;亞熱帶常綠闊葉林與溫帶落葉闊葉林的分界線;耕地中水田和旱地的分界線等;結(jié)合題意。故選:A。

【題目】 When I was in high school, I worked parttime helping Dad sell fruits and vegetables at a market. One day, as I was preparing the fruits, a little boy came by with his mom and sister. He was about eight years old, and the girl, five or six. They were looking at the fruits in front of me. I heard the kids say to their mom(in French),“They're good!” I knew it was French, because I can speak and understand it.

Then I noticed how the mom was picking the fruits. At first I thought she was really looking at the fruits because she was facing them, but then I noticed how much she had to feel and smell each one as she picked them out. And she often asked her son if it looked okay, but looked way above where his face was. Putting what I saw together, I was sure she was blind.

Both of the kids continued to help their mom pick out the fruits. The son made sure the fruits were not obviously bad, and the daughter handed them to her mom. The woman then felt each one and smiled, and the daughter would put them into their basket. The kids were smiling while helping their mom pick the fruits out.

Their smile and gentle manner moved me in a way that never happened before. It was so beautiful to see such young kids so willingly help. Most kids that age would be picking out candies or toys in a store for themselves, instead of helping their mom pick out fruits, as the two kids did.

It was great to witness the moment, but not so great because I didn't tell the mom how beautiful her children were in their language. This is what I regret to this day.

1When the writer was preparing the fruits, a little boy came by with________.

A.his classmates and friendsB.his parents and sister

C.his mom and sisterD.his mom and brother

2The woman and her kids came to the market to buy________.

A.fruitsB.basketsC.candiesD.toys

3According to what he saw, the writer was sure the mother couldn't________.

A.speakB.seeC.smellD.hear

4The writer was moved because________.

A.the mother was brave to face her problemsB.the kids were polite and kind to each other

C.the mother was careful in picking out thingsD.the kids were so willing to help their mother
