语法单选题系列43(提高篇） 1．The human body consists of organs, each ____a definite job to do. A. have B. to have C. has D. having 【答案】D 【解析】考查独立主格结构。独立主格结构是由名词+其它成分构成，不是句子，但是作用相当于句子。本题两部分之间没有连词，说明后半部分不是句子，而是短语。排除AC。Each与have构成主动关系，故使用现在分词的形式。each having a definite job to do=and each has a definite job to do.故D 正确。 2． Do you think this shirt is too tight ____ the shoulders? A. at B. on C. to D. across 【答案】D 【解析】考查介词辨析。At在…方面；on在…上；to…对…;across横过…；在…对面；句意：你认为这件衬衫在过肩膀的地方太紧了是吧？根据句意说明D正确。 3．As is known to all, Montreal is the second largest French-speaking city in the world, ______． A．Paris is the largest B．Paris the largest C．Paris to be the largest D．Paris be the largest 【解析】：考查独立主格结构。两部分之间没有连接词，说明后面不能是句子，只能是短语，作用相当于句子。Paris the largest= and Paris is the largest.故B正确。 |
