解析
试题分析:operate on对……做手术; operate for运营。句意:在医院里,马大夫过去常常给两到三个人做手术。used to do表示过去常常做某事,to是不定式符号,后面接原形动词,结合语境可知选A。 点评:解答此类题型的要点是了解各个短语的基本含义及用法的不同,同时注意其表示多个含义的现象,然后结合语境选择合适答案。注意当短语由动词+介词构成时,此类短语相当于及物动词,其后必须带宾语,但宾语无论是名词还是代词,都要放在介词之后。如果短语由动词(vt.)+副词构成,此类短语可以带宾语,宾语若是名词,放在副词前后皆可;宾语若是人称代词,只能放在副词的前面。由动词(vi)+副词。构成的短语属于不及物动词,不可以带宾语。 |
