想請教一下,,attemp to 與attempt at的差別,,

1、before so that，no comma is needed；

2、so that 从句表示结果，for example：

249. Although the manager agreed to a more flexible work schedule, he said that it must be posted on the bulletin board so that both management and labor will know what everyone is assigned to do.

3、D：that unlogically modify blunders.

但是，attempt to/at 的区别，我也不清楚，请大家继续讨论。

我也不太清楚attempt to 和attempt at的区别, 用attempt to多了, 总想排除掉attempts at.

不过我觉得B是对的有两点.

1) 如winnie讲的so that.

2) so that several attempts at revising corporate strategies have failed to correct (??)

我觉得这里省略了strategies.

请NN指点.

my understanding:

attemp to do 中的 attempt 是 vi. 动词短语

attemp at doing 的 attemp 是 n. 名词短语, 其后还要有动词的。

假如把B的attempts at 改成attempts to是否可以呢? 请NN指点.

Og 6. In virtually all types of tissue in every animal species, dioxin induces the production of enzymes that are the organism’s attempt to metabolize, or render harmless, the chemical irritant.

The noun attempt could follow organism’s; also, it would parallel the noun enzymes, and parallelism is needed here because the sentence uses the linking verb are to equate enzymes and attempt.

when attempt is a noun, attempt to/at应该都是ok的。
