1. It is recommended that ____________________ (工程不動工)until all preparations have been made.
    2. ______________________ (而不是讓蔬菜爛掉)，he sold them at half price.
    3. ______________________ （這個陌生人占這位年輕姑娘的便宜）and cheated her out of five dollars.
    4. ______________________ (事實既然如此)，there are no grounds to justify your complaints.
    5. We ______________________ (已投入所有的時間和精力)in this plan, and we don’t want it to fail.
    答案：
    1. It is recommended that the project not be started (工程不動工)until all preparations have been made.
    (本題考查虛擬語氣，根據(jù)主句中的recommended 可知從句部分應(yīng)用虛擬語氣，即所填內(nèi)容應(yīng)用虛擬語氣?！肮こ獭辈皇恰皠庸ぁ钡倪壿嬛髡Z，故應(yīng)用被動語態(tài))
    2. Rather than allow the vegetable to go bad (而不是讓蔬菜爛掉)，he sold them at half price.
    (本題考查rather than 的用法，rather than 意思為“而不是”是連接詞，連接平行結(jié)構(gòu)，，還考查“allow…to do sth”)
    3. The stranger took advantage of the young girl （這個陌生人占這位年輕姑娘的便宜）and cheated her out of five dollars.
    (本題考查固定短語和時態(tài)，take advantage of意思為“占便宜，欺騙” )
    4. Such being the case (事實既然如此)，there are no grounds to justify your complaints.
    (從句部分是一個獨立主格結(jié)構(gòu)，前后主語不一致，考試大在句中做條件狀語)
    5. We have invested all our time and effort (已投入所有的時間和精力)in this plan, and we don’t want it to fail.
    (本題考查動詞“invest”的用法，invest意思是“投入時間，金錢精力”，后接介詞in)
