efforts

all the effort 与all the efforts 的区别主要是：all the effort 常用语口语中；而all the efforts则比较正式。例如：

1. But all the effort of nine days - or seven years - should not be lost.

但是即使是失败了,这九天又或者说是七天的努力也不能说是白费了。

2. Seeing his expression after the race made it worth all the effort.

在赛后看着他的表情使得所有的努力都变得值得。

3. The deep mud negatived all the efforts to advance.

这路太泥泞使所有前进的努力都白费劲。

4. So despite all the efforts, they still take no breakfast.

所以,尽管费尽周折, 他们仍然不吃早饭。
