He is still green at this job. 他对这件工作还很生疏。

　②be careful with小心

5．It was a bit green. 它有点生。

　①a bit和a little在肯定句中修饰动词、形容词、副词及其比较级，可以换用。表示"一点儿"。如：

　　The speaker spoke up a bit/ a little so as to make himself heard more clearly.

　②a bit和a little在否定句中，意思正好相反。

　　not a bit=not at all

　　not a little=very much

　　试比较：I'm not a bit tired. 我一点也不累。

　　　　　　I'm not a little tired. 我非常累。

　③a little可直接作名词的定语，而a bit则要在后面加of构成短语才能作定语，二者都只能修饰不可数名词。如： There's only a little/ a bit of food left for lunch. 午餐只剩一点儿食品了。

　注意：a bit of的复数是bits of，而a little不能变复数。

6．And I advise you not to eat fruit that isn't ripe in the future.

　1）advise意为"建议，忠告，劝告"，常用于下面五种结构：

　①advise+n./ pron.

　②advise sb.（not）to do sth.

　③advise doing sth.

　④advise sb. against（doing）sth.

　⑤advise sb. +that sb.（should）do sth. （从句中用should do的虚拟语气）

　　The doctor advises a change of air. The doctor advised me to take more exercise.

　　We advised waiting till the proper time. His parents advised him against (doing) wrong.

　　I advised him that he (should) attend the meeting.

　advice是advise的名词形式，它是一个不可数名词。常用于：give（some）

　　advice on sth./ how to do...；ask for advice; follow/ take sb's advice等。

　2）in the future作"将来"（in time yet to come）解。

试比较in future作"今后"（from now on）解。例如：

You'd better not go out alone in future. No one knows what will happen in the future.
