As 四个常见用法

“As” 一词拼写简单，用法可不少！“Work as a waitress” 是什么意思？“As…as” 的句式用来做什么？如何用 “as” 表示两件事情同时发生？看视频，跟主持人 Sam 巩固复习 “as” 的四个常见用法。

'As' is tiny, but mighty. You can use it in lots of different ways. So, let's have a look at four of them together.

You can use 'as' – number 1 – to compare two people or things.Tokyo is as big as Los Angeles (more or less)

Number 2 – to describe somebody's job:I used to work as a waitress. (And no, I wasn't very good)

Or to describe something's function:Did you know that you can use olive oil as shampoo? Me neither!

Number 3 – to say that something happened at the same time as something else.You rang me just as I was texting you.

Number 4 – to give a reason like 'because'.As the sun is shining today, I think I might go for some fresh air after this.

And as you have hopefully been learning something new, why don't you practice one of these in the comments now?

1. 用 “as” 来比较两个人或事物。搭配 “as…as” 可以表示 “一样，不分伯仲”My house is very small – hers is twice as big.He is as tall as his brother.

2. 用 “as” 来描述人的职业或事物的功能。He works as a nurse.You can use coconut oil as cooking oil.

3. 用 “as” 描述两件事同时发生。I was just thinking about you as you rang.The doorbell rang as I was cooking.

4. 用 “as” 引出原因，类似于 “because”。I didn't go to the party as I was tired.I forgot to send the email as I was stressed.
