1.C
【句意】他上周提出的将高速公路延伸到市中心的提议在委员会审议中被否决了。
【解析】词组辨析。cut through“刺穿;抄近路走过”;bring(其过去分词为brought)about“导致，引发;使掉头”;throw(其过去分词为thrown)out“扔掉;伸出;否决”;make(其过去分词为made)up“组成;补足;化妆;编造”。填入的动词词组的过去分词形式构成被动语态，其动作承受者是proposal“提议”，由句中关键词“proposal提议”与“in committee在委员会审议中”可知“否决”符合语境，因此答案选C。
2.A
【句意】在我们第一年的教师培训期间，我们经常拜访当地学校去观察授课。
【解析】名词词义辨析。observation“观察;监视”;investigation“调查”;inspection“视察，检查”;examination“考试;检查;查问”。由关键信息“first teacher training year第一年的教师培训”知“观察授课”更符合语境，由此知A项正确。
