英文原文：

Hello everyone! Tom here from BBC Learning English in London. I'm going to explain the expression 'used to'.

'Used to' describes repeated actions or habits in the past.

For example, 'I used to play football after school'.

And it can also describe states or things that happened over a long period of time.

For example, I used to live in Japan.

We can also use 'used to' in the negative form, we just add 'did not' or 'didn't'.

Using our first example, I could say 'I didn't use to play football'.

But be careful! With negative and question forms, we don't include 'd' at the end of 'used'.

中文翻譯：

大家好！我是來自倫敦BBC Learning English的Tom。我將解釋“used to”這個表達方式。

“Used to”用于描述過去的重復(fù)動作或習(xí)慣。

例如，“我曾經(jīng)放學(xué)后踢足球”。

它還可以描述長時間發(fā)生的狀態(tài)或事情。

例如，“我曾經(jīng)住在日本”。

我們也可以用否定形式的“used to”，只需加上“did not”或“didn't”。

使用我們的第一個例子，我可以說“我曾經(jīng)不踢足球”。

但要小心！在否定和疑問形式中，我們不在“used”結(jié)尾加上“d”。
