Question

9．The little girldidn't stop crying until her mother came back．（直到她媽媽回來才停止哭）．（until）

Answer 1

分析 didn't stop crying until her mother came back．

解答 答案：didn't stop crying until her mother came back．這里是說過去的事情應(yīng)用一般過去時，要表達(dá)直到…才用not…until，停止做某事用stop doing sth，stop是實(shí)意動詞，故借助于did構(gòu)成否定句，哭cry，故didn't stop crying，從句中主語是her mother，回來come back，過去式came back，故答案是didn't stop crying until her mother came back．

點(diǎn)評 本題是not…until的應(yīng)用，這里是主句從句都用過去時，但如果主句用將來時則從句用一般現(xiàn)在時，如：I won't go to bed until my mother comes back
