单项选择题

All her life, my mother wanted busy children. It was very important that her house should remain at all times clean and tidy.
You could turn your back for a moment in my mother’s house, leave a half written letter on the dining table, a magazine open on the chair, and turn around to find that my mother had "put it back where it belonged," as she explained. My wife, on one of her first visits to my mother’s house, placed a packet of biscuits on an end table and went to the kitchen to fetch a drink. When she returned, she found the packet had been removed. Confused, she set down her drink and went back to the kitchen for more biscuits, only to return to find that her drink had disappeared. Up to then she had guessed that everyone in my family held onto their drinks so as not to make water rings on the end tables. Now she knows better.
These disappearances had a confusing effect on our family. We were all inclined to forgetfulness, and it was common for one of us, upon returning from the bathroom, to find the every sign of his work in progress had disappeared suddenly. "Do you remember what I was doing" was a question frequently asked, but rarely answered.
Now my sister has developed a secondhand love of clean windows, and my brother does the cleaning in his house, perhaps to avoid having to be the one to lift his feet. I try not to think about it too much, but I have at this later time started to dust the furniture once a week.

The underlined part in the fourth paragraph suggests that my sister ______.

A．is happy to clean windows
B．loves to clean used windows
C．is fond of cleaning used windows
D．likes to clean windows as my mother did

问答题

2004年3月，A市甲公司与B市乙公司在商品展销会上签订了一份成衣购销合同。合同约定：甲公司为乙公司提供一批优质成衣，总价款50万元，由甲公司代办托运，货到付款。并约定违约金为合同价款的10%。8月16日，甲公司将货物交乙公司指定的承运人A市铁路运输公司运输。8月18曰，火车行至B市边界，由于突发泥石流，这批货物全部被洪水冲走。9月1日，甲公司向乙公司催要货款。乙公司以未收到货物为由，拒绝付款，并要求甲公司支付违约金，并赔偿其因此受到的损失。甲公司提出其已将货物交给承运人，责任应该由承运人负担。A市铁路运输公司也多次向乙公司索要运费。为此，三方争执不下。乙公司于是向B市人民法院起诉。 问题：

假如该批货物并未损失，只是由于甲公司交货迟延，致使乙公司错过了销售旺季，不得不低价销售，损失5．5万元。那么在甲公司支付了5万元的违约金后，乙公司能否继续要求甲公司赔偿为什么
