◎ 他把蛋糕分成4块。
He divided the cake into four pieces.
二、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.
三、分解法
就是把一个句子分成两个或两个以上的句子。这样既能把意思表达得更明了，又能减少写错句子的几率。如：
◎ 我们要干就要干好。
If we do a thing, we should do it well.
◎ 从各地来的学生中有许多是北方人。
There are students here from all over the country. Many of them are from the North.
四、合并法
就是把两个或两个以上的简单句用一个复合句或较复杂的简单句表达出来。这种方法最能体现学生的英语表达能力，同时也最能提高文章的可读性。如：
◎ 我们迷路了，这使我们的野营旅行变成了一次冒险。
Our camping trip turned into an adventure when we got lost.
◎ 天气转晴了，这是我们没有想到的。
The weather turned out to be very good, which was more than we could expect.
◎ 狼是高度群体化的动物，它们的成功依赖于合作。
Wolves are highly social animals whose success depends upon
