My foot：你是学它的中文还是它的英语意思？

学英语的实质就是训练我们用英语遣词造句的能力。要训练出用英语遣词造句的能力，就必须训练把英语学成英语的能力。可是，学习或见到作为idiom使用的英语my foot时，你是只学习它的中文意思，还是学习它的英语意思从而给自己一个英语遣词造句的锻炼机会？

1) 我们先读下面出现的高中英语：

1. my foot：An exclamation of disdain or disagreement.

2. My foot! Informal English： I do not believe it ! Like hell!

3. my foot! used to express strong contradiction or disbelief

4. my ˈfoot! (informal, humorous) ：a strong way of saying that you disagree completely with what has just been said.

2) 接下来，我们可以把我们学过的（高中）英语用起来，做英语遣词造句能力训练了：

1. Okay.I got you. My foot is informal English.It is an English idiom.

2. Okay. I got you. When people say My foot, My foot means I don't believe it,or Like hell.

3. When you say My foot, you show a strong disbelief of something.

For example,you can say：

1. Mary can’t come because she’s tired.

’Tired ? my foot! Lazy more like!’

2. You’re the best in town, my foot!

3) 我们也可以反过来训练使用My foot：

Well,next time when yoy mean I don't believe it, don't say I don't believe it.You will say：My foot! (instead)

所有的英语学习都不是为了给你将来有机会用的，所有的英语学习只是为了现在给你一个机会把学过的英语I don't believe it.I disagree with it用起来，给你一个机会“用”英语I don't believe it.I disagree with it的，给你一个英语遣词造句的机会Okay.I got you.When you say My foot,you mean You don't believe it的。

如果你只“用”中文“鬼才相信”，你将失去这些锻炼的机会。
