题目内容
19.The policeman kept his eyes________on the screen of the computer to identify the criminal's footprints.( )A. | fixing | B. | fixed | C. | to fix | D. | being fixed |
分析 警察把眼睛盯着电脑屏幕,辨认罪犯的脚印.
解答 答案是B.本题考查过去分词;题干中需要的是宾语his eyes的补足语,fix 为及物动词,与his eyes之间是动宾关系,故用过去分词,答案选B.现在分词的被动语态表示被动的进行中的动作,不符合语境,故排除D.
点评 首先判断选项中的动词在句中是以谓语还是非谓语形式出现,然后根据选项在句中的功能结合非谓语的基本用法做出合理的判断.
