　　答案

　　21.【答案】A。解析：句意：——我听说你，上星期检查过胃了?——是的。但我希望我永远不会再遭遇到这种不愉快的经历。undergo经历;undertake承担，保证;undercharge充电不足;underline强调。故本题答案选A。

　　22.【答案】A。解析：句意：哎呦!我把自己烫伤了!我摸了一个热壶。touch触摸;keep保持;feel感觉;hold拿着。所给的语境是“烫伤”，因为触摸，才可能烫伤。故本题答案选A。

　　23.【答案】C。解析：句意：研究表明婴儿在出生前就能辨别声音，他能在一群女人中听出妈妈的声音。suspect怀疑;compromise妥协;discriminate辨别;inspect检阅。根据“They can recognize their mother’s voice among a group of women.”可知此处表示“辨别”，故本题答案选C。

　　24.【答案】B。解析：句意：玛丽最终接受布鲁斯作为她的终生伴侣。received收到;accept接受(含有主观成分);made使，不能与as连用;honored授予荣誉。选择终生伴侣而不是授予荣誉，故本题答案选B。

　　25.【答案】C。解析：句意：去参加晚会吧，把这些碗盘留给我洗。get使;remain剩下，依然;leave使留下，交给，遗留;send送，寄，派。get与remain意思不符，send与此句的语言环境不相协调。故本题答案选C。
