10、 , when)+形容詞如：Work hard when (you are) young ,or you'll regret.趁年輕要努力學習，要不然你會后悔的。連詞(whether, as if ,while )+介詞短語如：He looked everywhere as if (he was)in search of something .他到處看似乎在找什么東西。連詞(when , while , though )+ 現(xiàn)在分詞如：While (he was) holding talks with President Hu Jintao , US President George
