backs

at the back of, in the back of

这两个短语的意思相近,都是“在…后面”的意思。它们的区别在于:

1.at the back of指在某地方之外的后面部分; in the back of的意思是指在某地方之内的后面部分。

2.at the back of也可引申为“支持”“在…印象中”,而in the back of没有此义。

turn one's back on, turn one's back to

两者不同义,前者含有轻蔑的感情色彩,而后者没有这种色彩。例如:

In the old society, the rich always turned their back on the poor.在旧社会,富人总是瞧不起穷人。

But Jack has turned his back to the trouble over it.可杰克并不把这件麻烦事放在心里。

下面两句意思不同:

Stand back, please.

请往后站。

Stand behind, please.

请在后面站着。
