attempt的用法:

1.attempt后可加不定式，如attempt to do，也可加介词和动名词勾结，如attempt at doing，不过习惯上，不定式的用法更为普遍；

2.作为名词时，attempt是指可数的尝试，要注意不能随便省略掉冠词an，如make an attempt。也可以说an attempt to do it和an attempt at doing it，或者是不用冠词，如make little attempt，without attempt；

3.使用attempt时，要注意双重否定的错误。

The work was attempted to be done quickly.

第一句的说法是错误的，第二句才是正确的，指“尝试将工作做得更快”。
