Question

【題目】The boy found himself in a bad situation when________in the river.

A.swimmingB.swimsC.to swimD.swam

Answer 1

【答案】A

【解析】

句意：那男孩在河里游泳時(shí)發(fā)現(xiàn)自己處境很糟。

考查動(dòng)詞形式。when引導(dǎo)的時(shí)間狀語(yǔ)從句，若從句的主語(yǔ)與主句的主語(yǔ)相同時(shí)，從句的主語(yǔ)省略，并將謂語(yǔ)動(dòng)詞變成分詞。句中主語(yǔ)與游泳之間為主動(dòng)關(guān)系，用現(xiàn)在分詞。例如，When you do the work, you should be careful.=When doing the work, you should be careful.故選A。
