还原法

　　即把疑问句、强调句、倒装句等还原成基本结构。这是避免写错句子的一种有效的办法。如：

　　◎　这是开往格拉斯哥的火车吗?

　　Is this the train for Glasgow?

　　还原为陈述句：This is the train for Glasgow.

　　◎　他是因为爱我的钱才同我结了婚。

　　It was because he loved my money that he married me.

　　还原为非强调句：Because he loved my money, he married me.

　　◎　光速很快，我们几乎没法想像它的速度。

　　So fast does light travel that we can hardly imagine its speed.

　　还原为正常语序：Light travels so fast that we can hardly imagine its speed.
