问题 单项选择题

各品种的葡萄中都存在着一种化学物质,这种物质能有效地减少人血液中的胆固醇。这种物质也存在于各类红酒和葡萄汁中-,但白酒中不存在。红酒和葡萄汁都是用完整的葡萄作原料制作的;白酒除了用粮食作原料外,也用水果作原料,但和红酒不同,白酒在以水果作原料时,必须除去其表皮。
以上信息最能支持以下哪项结论

A.用作制酒的葡萄的表皮都是红色的。

B.经常喝白酒会增加血液中的胆固醇。

C.食用葡萄本身比饮用由葡萄制作的红酒或葡萄汁更有利于减少血液中的胆固醇。

D.能有效地减少血液中胆固醇的化学物质,只存在于葡萄的表皮之中,而不存在于葡萄的其他部分中。

答案

参考答案:D

解析:题干断定:
第一,能有效地减少人血液中的胆固醇的化学物质,普遍存在于葡萄中。
第二,能有效地减少人血液中的胆固醇的化学物质,只存在于红酒中,不存在于白酒中。
第三,红酒是用完整的葡萄作原料的,白酒用葡萄作原料时,必须去掉其表皮。
根据以上断定,不难回答下述问题:为什么白酒和红酒都取葡萄作原料,而那种化学物质又普遍存在于葡萄中,但只有红酒含有那种物质,而白酒却不含有呢一个合理的结。
论是:这种物质只存在于葡萄的表皮中。这正是D项所断定的。
其余各项均不能从题干中推出。

I grew up with a fat dad—450 pounds at his heaviest.Every week he would try a new diet,and my family ended up eating whatever strange food he was trying at that moment.

After my third­grade year,my dad landed a life­changing job in Manhattan.My mom,my little sister and I had to move away from our hometown,Chicago,and leave my grandmother and her beautiful food behind.

Leaving my grandmother was far more frightening than the move to New York City.There would be no more special weekends at my grandmother’s house,the only place I can remember feeling happy,safe and nourished (有营养的).It was what I desired.In this new city,I felt extremely alone and lost,and I missed my grandmother terribly.

My grandmother knew just how I felt—And she knew the cure.Every week,she would send me a card with a $20 bill,a recipe and a list of what to buy at the market.It kept us bonded,and her recipes filled my body and soul.

Over the years,I have grown to better understand my father’s struggles with weight and the toll (代价) it took on him and those who love him.I have come to realize he was driven not by vanity (自负) or selfishness as much as by a deep pain.And in spite of growing up in such an unhealthy eating environment (or perhaps because of it),as an adult I found a passion and a career as a nutrition consultant.

Today,my father weighs 220 pounds and is a vegan (素食者).How he got there is a story I hope to share in the coming weeks.More importantly,food is no longer a barrier that keeps us apart,but a bridge that keep us connected.There is nothing my dad enjoys more than talking with me about dietary theories and his weight­loss victories.And now I am the one regularly sending recipe cards to my father’s house,just as my grandmother did for me.
