Dear Shelly,

I am writing to apologize for not watering your lilies while you were away, that caused their death. Now let me explain what happened to me or my family.I was so busy preparing for coming exam that I had no time for other things. Also, my mother had her ankle injuring while she was walking. I had to take good care of her, who stay home alone. That was because I failed to water your favourite plant. I would like to buy some new one as a compensation for its loss. Please forgive for me.

I sincere hope you can accept my apology.

事。

19．B 天气好的时候，很难找到理由表达对这个城市沮丧或不满意之情。故选B项。

20．C 根据空后的or dissatisfied可知，此处需要一个与dissatisfied有同样感情色彩的词。depressed“沮丧的”，符合语境。故选C项。

21．A Tulic并不是来旅行的，因此C、D项不正确；而下文也没有说明她当时特别着急，因此B项也不正确。故选A项。

22．D 根据本段第一句“Yet her time in New York had coincided with endless ugliness.”及本段最后一句“…‘Enough of this craziness.’”可知，她在纽约的日子不太好，因此她想看到一些好的东西。故选D项。

23．A 根据上文的towards the subway station及下文的waiting for the train可知，她在地铁站。故选A项。 24．B 此处表示“一个人斜靠着柱子”。lean against sth为固定搭配，意为“斜靠在”。故选B项。 25．C 由空后的“…the next train was two stations away.”可知，此处指的是火车还有两站就进站了，这个通知打破了平静。故选C项。

26．D 根据全文内容可知，此处表示“就在这时，Tulic看到靠着柱子的那个人掉到了铁轨上”。glimpse“瞥见”，符合语境。故选D项。

27．B 根据语境可知，另外一个也在站台上等车的人看到这个场景后跳到了铁轨上，且根据下文可知他是第一个去救人的。故选B项。

28．A 解析见上一题。上文中的collapsing forward onto the tracks也是提示。故选A项。 29．C 此处的the man是指掉下去的那个人，他在铁轨上一动不动。故选C项。

30．D Tulic当时感到很意外，不知道这些人的机智和快速反应能力是从哪里来的。故选D项。 31．A 根据空后的“…know that the train was coming.”可知，他们非常紧张。故选A项。

42．whether 考查连词。whether…or not是否……。根据语境“他通过仔细轻拍胸部来判断是否有疾病”可知填whether。

43．in 考查介词。be interested in对……感兴趣。

44．extremely 考查副词。修饰形容词fat需用副词extremely。

45．was walking 考查动词时态。“when＋进行时”表示“某人正在做某事的时候，突然……”，又因为本文叙述的是过去的事情，故填was walking。

46．taking 考查非谓语动词。该句省略了主语，take与he之间是主动关系，故用现在分词taking作状语。 47．their 考查物主代词。修饰名词breathing需用形容词性物主代词their。
