很多人都强调用连词、介词等词汇手段迅速提高语言水平。但这种方法需要一定的积累。而通过对低级句型的改造，可以迅速达到这一目的。
●强调句：可以轻松地将时间、地点、原因、方式等类型状语从句转变为强调时间的强调句。
It was not until I arrived home that I realized I had left the bag on the shop counter.
●倒装句：只要句中有介词短语或状语从句，便可将其提前，变成倒装句。
Only when I turned right at the crossing did that car crack towards me.
Only by this means can he escape from the big fire.
●with引导的伴随结构：可以将状语从句或并列句中的其中一个分句变成with结构。
With the sun lighting brightly and the birds singing clearly, I went to school in high spirits.
●巧妙地使用非谓语动词：可以将状语从句或并列的动词简化为非谓语动词。
Hearing that, the driver’s wife quickly added that her husband often talked nonsense after drinking.(低级形式：When he heard that, ……)
●恰到好处的被动句：适合应用于较简短的句子，这样显得语言简洁生动，宾语一般是nothing、anything、everything等不定代词。
I searched all my pockets, but nothing was found.
●感叹句：通常用于开头结尾活跃文章气氛，凡是“I feel ……”之类表达感情的句子皆可如此改造。
How terrible I felt today! I failed again in the math exam.
●高级定语从句：若定语从句中的动词带有介词，只需将介词移至先行词后。
We came to a place to which they had never paid a visit before.
●进行时态：有时会含有一定情绪，尤其要使用always这样的富含感情色彩的副词。
●婉转表达：需要使用幽默的技巧，主要用于漫画型作文题。
I could find nothing but bad luck when I returned the shop after learning that my handbag had been left on the counter.
●what引导的名词性从句：将动宾结构转化为此结构。
What he gave me, which I knew, were not only a Christmas present but also a heart full of love and a mind of my existence in it.
●“数词+名词”变为“as many as+数词+名词”
As many as ten years ago, my hometown used to be covered by forests.
●适当加一些不关痛痒的插入语：一些连词、副词可以放到句子中间充当语气较弱的插入语，如I guess、however、in a way、certainly、in my opinion、probably、briefly等，有时可以考虑几个插入语连用，就更像英美人士的文章了。
●独立主格：将主从句去掉连词，前句动词变为分词即可。
The weather being fine, a large number of people went to climb the Western Hills.
