学了这么多年英语不知道“when”和“while”到底啥时候用？看了你就明白了！

TWO SIMULTANEOUS CONTINUOUS ACTIONS = WHILE

两个同时进行的连续动作= WHILE

Let me explain, we use while and when when two things are happening at the same time. Now, when we have two continuous actions happening at the same time, then we usually use while.

我来解释一下，我们通常在同一时间发生两件事时用while和when。当我们在同一时间发生两件持续的动作时，那么我们就会用while。

Right now, I’m recording a video while my husband is working. We have two continuous action, I’m recording and my husband is working. So I’m recording a video while my husband is working.

现在，我正在录制视频，而我的丈夫正在工作。我们都有两个持续进行的动作，我的是正在录制，而我丈夫是正在工作。所以我录视频while我丈夫工作。

Or here’s an example in the past, last night, I was watching TV while my father was sleeping. Again, we have two continuous actions. I was watching TV and my father was sleeping. I was watching TV while my father was sleeping. With two continuous actions, we usually use while.

再举一个过去时的例子，昨天晚上，我正在看电视，我的爸爸正在睡觉。好的，我们这里就又有两个同时持续发生的动作，那就是我正在看电视，我爸爸正在睡觉。所以是我看电视while我爸爸睡觉。有两个正在持续的动作，我们就用while。

TWO SINGLE ACTIONS AT THE SAME TIME / ONE IMMEDIATELY AFTER ANOTHER = WHEN

在同一时间发生两个动作/一个接一个=WHEN

Now, when we have two single actions that happen at the same time or>You can see that we have two verbs there in the simple past, not continuous.

当我们有两个在同一时间发生的两件事或者我们看到过去有两个并不是持续发生的动词出现。

The phone rang and I picked up. I picked up the phone when it rang. We have two single actions that happened very close together, almost at the same time and so we use when.

手机响了，我去接。当手机响时我去接电话。我们有两个独立的动作几乎一起发生在非常相近的时间，我们就用when。

Another good example would be when I get home, I take off my shoes. That’s also two single actions. I get home and I take off my shoes. When I get home, I take off my shoes. Or you could say it the other way, I take off my shoes when I get home.

另外一个非常好的例子就是，当我到家时，我脱鞋。这同样压实两个独立的动作，我到家和我脱鞋。当我到家，我就脱鞋。或者你可以换个说法，我脱鞋在我到家的时候。

Both while and when are used when two things happen at the same time, but we tend to use while with two continuous actions and when with two single actions.

While和when都用在同一时间发生两件事时，但是我们更倾向于在两件同时持续发生的动作时用while，而when则用在分别发生在同一时间的两个动作。
