Question

10．當李娜獲得網球比賽冠軍時，我們都忍不住歡呼起來．
All of uscouldn't help cheering up when Li Na became the world champion in the tennis competition．

Answer 1

分析 couldn't help cheering up

解答 答案：couldn't help cheering up．根據中英文對照后得知這里缺少忍不住歡呼起來的表達，忍不住做某事，用can't help doing sth，歡呼用短語cheer up，故can't help cheering up，再者這里的從句部分became是過去時，故前面也應時態呼應，故用can't的過去式couldn't，故答案是couldn't help cheering up．

點評 本題需要對照中英文得出固定句型，最后要看看整個句子是否有語法錯誤
