語法精講
1. 簡介
倒裝有兩種。將主語和謂語完全顛倒過來，叫做完全倒裝（complete inversion）。
【例】Then began a bitter war between the two countries. 于是兩國之間開始了惡戰(zhàn)。
只將助動詞（包括情態(tài)動詞）移至主語之前，叫做部分倒裝（partial inversion）。
At no time can the entrance be left unguarded. 入口需要隨時有人把守。
2. 四級必考句型
（1） Among the disadvantages that may bring to are that + S. + V.， making + n. + adj.
【分析】有時候，為了強調(diào)“介詞 + 賓語”結(jié)構(gòu)，我們把它置于句首，此時句子需要全部倒裝，在本句中我們把謂語動詞“are”放在了主語結(jié)構(gòu)“that…”的前面。
Among the disadvantages that cars may bring to our lives are that we could spend more time in traffic jams and we would likely spend more money on operation and maintenance fees， making our schedules tighter and our pockets lighter！
（2） With these steps， we can change our society into one out of which comes the possibility that
【分析】句中的定語從句“out of which comes the possibility…”是完全倒裝句。
With these steps， we can change our society into one out of which comes the possibility that natural resources will be fully cherished.
（3） There is a real possibility that ， should there be a 。
【分析】Should there be a…是省略if并部分倒裝的將來時虛擬條件句。還原后為：If there should be a…
There is a real possibility that we can solve this problem completely， should there be cooperation among all parties involved.
（4） never， hardly， seldom， rarely， not， until…，scarcely， in no case（不管怎樣也不），in no way（不管怎么也不），by no means（決不），on no account（不論什么原因也不），at no time（無論什么時候也不）等否定詞放在句首時，句子要倒裝。
By no means shall we cease to protect our environment.
（5） It was very late. Exhausted though she was， there was no hope of her being able to fall asleep.
【分析】從屬連詞as和though也可以用于讓步狀語從句中。這種從句必須以形容詞（或形容詞化的分詞）、名詞或動詞原形開頭，主句必須位于從句之后。
1） Small as a bicycle is， it can bring a lot of convenience to our lives.
2） Foolish though he looks， he always seems to make the wisest proposals. （他看起來樣子傻傻的，可似乎總是能提出最聰明的建議。）
3） Try as you may， you will never succeed. （你盡管可以試，但決不會成功）。
