「As」 一字拼寫簡單,用法可不少!「Work as a waitress」 是什麼意思?「As…as」 的句式用來做什麼?如何用 「as」 表示兩件事情同時發生?看影片,跟主持人 Sam 鞏固複習 「as」 的四個常見用法。


‘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?
