Hayley教口語，“不善表達(dá)”用英語怎么說？

to be shy and not often express wishes or opinions

害羞，不善表達(dá)。

Here 'backward' means shy or unwilling; 'come forward' means present oneself into view.

這里backward的意思是害羞或不愿意;come forward意思是表達(dá)自己。

I'm sure Matt will tell you what he thinks of the idea - he's not usually backward in coming forward.

我相信馬特會告訴你他對這個觀點的看法——他一向很直爽。

Although they are rich, they are rather backward in coming forward with the poor.

他們雖然有錢，但在幫助窮苦人方面卻不大踴躍。
