关于我国河流的叙述,错误的是(  )

A.我国大多数河流自西向东流入太平洋

B.东部地区的河流冬季普遍有结冰现象

C.西北广大地区大多数的河流为内流河

D.外流区的河流,长江汛期是最长的

答案

受地形地势的影响,我国大多数河流自西向东流入太平洋.我国外流河的水文特征深受季风气候的影响.随着雨带由南向北推移,河流水量骤增,水位上涨,形成汛期.随着冬季风的加强,雨带南撤,河流的水量减少,水位逐渐下降,河流进入枯水期.以秦岭-淮河为界,以南地区的河流流经湿润地区,水量丰富,汛期长,含沙量少,冬季河流不结冰.以北地区的河流流经半湿润或半干旱地区,水量不大,汛期较短,且冬季河流有结冰现象.辽河、海河、黄河等河流的上、中游地区水土流失严重,河水的含沙量很大.与外流河相比,我国内流河的水文特征明显不同.这些河流多分布在西北内陆.这里降水稀少,气候干旱,河水主要来自高山冰雪融水.夏季,随着冰雪融化,内流河水量增多;夏季过后,河流水量逐渐减少,甚至断流.所以,内流河大部分属于季节性河流.

故选:B.

I was in a rush as always, but this time it was for an important date I just couldn’t be late for! I found myself at a checkout counter behind an elderly woman seemingly in no hurry as she paid for her groceries. A PhD student with not a lot of money, I had hurried into the store to pick up some flowers. I was in a huge rush, thinking of my upcoming evening. I did not want to be late for this date.

We were in Boston, a place not always known for small conversation between strangers. The woman stopped unloading her basket and looked up at me. She smiled. It was a nice smile –warm and reassuring—and I returned her gift by smiling back.

“Must be a special lady, whoever it is that will be getting those beautiful flowers,” she said.

“Yes, she’s special,” I said, and then to my embarrassment, the words kept coming out.

“It’s only our second date, but somehow I am just having the feeling she’s ‘the one’. Jokingly, I added, “The only problem is that I can’t figure out why she’d want to date a guy like me.”

“Well, I think she’s very lucky to have a boyfriend who brings her such lovely flowers and who is obviously in love with her,” the woman said.” “My husband used to bring me flowers every week –even when times were tough and we didn’t have much money. Those were incredible days; he was very romantic and – of course – I miss him since he’s passed away.”

I paid for my flowers as she was gathering up her groceries. There was no doubt in my mind as I walked up to her. I touched her on the shoulder and said, “You were right, you know. These flowers are indeed for a very special lady.” I handed her the flowers and thanked her for such a nice conversation.

It took her a moment to realize that I was giving her the flowers I had just purchased. “You have a wonderful evening,” I said. I left her with a big smile and my heart warmed as I saw her smelling the beautiful flowers.

I remember being slightly late for my date that night and telling my girlfriend the above story. A couple of years later, when I finally worked up the courage to ask her to marry me, she told me that this story had helped to seal it for her –that was the night that I won her heart.
