题目内容
2.The project they had devoted up to two years towas chosen(choose) as the best one at the conference.分析 他们已经投入了长达两年之久的项目,在这次大会上被选为最好的一个.
解答 答案:was chosen.首先要知道"they had devoted up to two years to"这部分是一个定语从句,主语是The project,也就是说空格处需要用choose的某种形式来做句子的谓语.根据"had devoted"可知是在这次大会之前的动作,所以主句要用一般过去时,另外对于The project来说,是被选出来的,主语project是动词choose的动作承受者,所以要用一般过去时的被动语态,其形式为was/were+及物动词的过去分词.主语为单数project,故填was chosen.
点评 首先要能熟练分析句子成分,然后找出句子的主语以及谓语动词,再根据句子提供的信息,确定要使用的时态和语态,最后确定正确答案.
