Remember type 1 conditionals use the present tense and will.

请记住一类条件句使用的是现在时和“will”。

First conditional: we use the first conditional when we talk about a possible situation in the future.

我们在谈论将来可能发生的情况时使用第一条件句。

Second conditional: we use the second conditional when we talk about imaginary situations or imaginary abilities and their results.

我们在谈论想象的情况或想象的能力及其结果时使用第二条件句。

Third conditional: we use the third conditional to talk about a situation in the past that didn't happen.

我们用第三条件句谈论过去没有发生的情况。

We've just said that the first conditional uses " if" in the conditional clause and " will" in the main clause.

我们刚刚已经说过，第一条件句在条件从句中使用 “will”。

So the second conditional uses a past simple verb in the if clause then 'would' followed by the infinitive verb in the main clause.

在第二条件句中，if 从句使用的是一般过去时动词，而主句是‘would’加动词不定式。

The second conditional uses the past simple after if then would and the infinitive, that's the most common, or would and the present continuous.

第二类条件句中，if 的后面是一般过去时，然后是 would 加上不定时，这是最常见的，或者 would 加上现在进行时。

So, that makes that third conditional and these are examples of a mixed conditional, using a past imaginary situation and how it affects the present. Mmm, yeah.

那么，这就是第三条件句，这些就是混合条件句的例子，使用一个过去想象的情况以及它如何影响现在。嗯，没错。

" If I had a lot of money, I would travel around the world." Once again, that's a conditional use of the word " if." There's also a common idiom related to whether, and that is " whether or not."

“如果我有很多钱， 我会环游世界。 ” 再一次，这是“如果”这个词的条件用法。 还有一个与是否相关的常见成语， 那就是“是否” 。
