【题目】—Is it true that Aaron refused an offer from Cambridge University yesterday?

Yeah, but I have no idea _________ he did it; that’s one of his favourite universities.

A. when B. why C. that D. how

【答案】B

【解析】考查同位语从句连词辨析。句意:——Aaron拒绝了耶鲁大学的录取,这是真的吗?——是的,我不知道他为什么要这样做。耶鲁大学是他最喜欢的大学之一。本句运用了同位语从句,对名词 idea 的内容进行的说明。短语 have no idea 后面可以跟不同连词引起的同位语从句。本句根据句意可知使用why表示原因。故选B。

【题目】阅读理解(每小题2.5分,共10分)

读下短文,从每题所给的A、B、C和D四个选项中,选出最佳选项。

My daughter Kelly is a cautious person. She needs to warm up to situations, is hesitant to try new things. When with close friends, she becomes a leader who laughs loudly and chants, Girls rule, boys drool. But when that comfort zone is not around her, she is shy and nervous.

This has been challenging for me at times. Shy is not a word that I think has ever been used to describe me. But this has been a year of firsts for my girl that has filled her with a new sense of confidence. This year she moved to lap lane in swimming where she was preparing for a swim team. This year she learned to ride a bike without training wheels. And this year she completed her first kids’ triathlon (三项全能) .

On Saturday, with a thunderstorm coming soon and my son’s birthday party later in the day, we all went out in the dark of the morning for Kelly to participate in her first triathlon. We practiced transitions from swim to bike to run with her, we got all the equipment she’d need, and we kept talking about the race. But as we waited the two hours for the older kids to finish before her turn, she held my leg a little harder and told me she loved me a few too many times. She was nervous but trying to keep it together.

And then it was her turn. From the second she jumped into the water, my heart soared. My daughter transformed into the most confident human being I had ever seen. She dominated(主宰) that swim, crushed that bike ride and ran to the finish with the biggest smile on her face.

I can honestly say that I never felt so proud of someone in my entire life. It wasn’t because she did a sport or anything like that. It was because she was afraid of something and conquered(克服) that fear with confidence and a fire I hadn’t seen before.

All day I would find myself just looking over at her and smiling. She might be wearing the finalist medal but I felt like I won that day. I won the chance to see my girl shine.

Shine on, sweet baby.
