这个句型可以说是所有表示“一个”的句型中最常见最简单的.只是……”。它可以用来描述当前的情况或动作，也可以用在过去的时间背景中。比如：

[注意]

尽快，尽快。比如：

Second, there is hardly . when .

这个句型的基本用法是：主语几乎没做什么.受试者是什么时候.使用时请注意：

1.这个句型描述的动作一般发生在过去。

2.主句的谓语动词用过去完成时，when从句的谓语动词用一般过去时。

Almost nothing can be replaced by almost nothing or very little.

比如：

Before she could sit down to rest, the phone rang again. She just wanted to sit down and have a rest when the phone rang again. )

需要注意的是，有时否定副词hardly、congress或rare可以放在句首，但这样会造成倒装句。例如，上面的句子可以改为：

Hardly had she had time to sit and have a rest when the phone rang again.

Three, soon .

这个句型几乎和hardly的用法一模一样.当.的时候.它的基本用法是：主语刚做完.比实验对象做的更多.使用时请注意：

1.这个句型描述的动作一般发生在过去。

2.主句的谓语动词用过去完成时，when从句的谓语动词用一般过去时。

比如：

She had just had time to sit down and have a rest when the phone rang again. She just wanted to sit down and have a rest when the phone rang again. )

需要注意的是，有时否定副词短语not happen可以放在句首，但会引起倒装。例如，上面的句子可以改为：

Fourth, the present clause

使用这种句型时，需要注意的是moment和从句之间不能插入其他成分。比如：

I want to see her as soon as she arrives. I want to see her as soon as she arrives. )

[注意]

类似的用法，除了moment，还有minute/second/instant从句。比如：

I want to visit him as soon as he arrives. I was about to call him when he came. )

V. Direct/Immediate Clause

这种句式比较少见。directly和immediately都用作连词。比如：
