【语法提要】

1.try out意为“试验;尝试”，是“动词+副词”结构的短语，常与动词不定式、介词for连用，用来引出参加的内容。

例句：The boy is trying out a new way.这个男孩正尝试一种新的方法。

2.be busy with sth.表示“忙于某事”，with后要接名词性的词或短语,相当于be busy doing sth. (不可用be busy to do sth.)

例句：He is busy doing his homework.= He is busy with his homework.

他正忙着做家庭作业。

3.be worried about…表示“担心，为……感到忧虑”，后接名词、代词、动名词作宾语。

例句：She is worried about your health.她为你的健康担心。

worried的动词形式是worry，意为“（使）担心，烦恼”。短语be worried about相当于worry about。

例句：I am worried about my father’s health.=I worry about my father’ health.我为我父亲的健康担忧。

【问题探究】

根据汉语意思完成句子。

1.我想下个周末去试坐一下这艘船。I wanted to try the boat out next weekend.

2.他忙于工作。He is busy with his homework.
