試題分析：
小題1:考查短語as soon as，一……就……。
小題2:考查短語固定搭配be good for，對……有好處。注意本句主語it是單數(shù)第三人稱，故系動詞用單數(shù)。
小題3:考查固定搭配help sb with sth幫助某人做某事。注意本句主語I是第一人稱單數(shù)，一般現(xiàn)在時態(tài)中謂語動詞用原形。
小題4:考查固定搭配not……until……，直到……才……。
小題5:考查take的用法。take 用于 it takes sb ... to do sth句型，僅指花費時間（three hours等），必須用it作形式主語，指代下文不定式內(nèi)容。注意本句描述的是過去發(fā)生的動作，故用一般過去時態(tài)。
