許多動(dòng)詞與某一小品詞搭配具有類似的含義，所以掌握英語短語和慣用語有一個(gè)重要的方法，那就是通過介詞或副詞之類的小品詞理解和歸納它們。以介詞on為例，它有“依靠，支撐”的意思，許多動(dòng)詞與on搭配都可以表達(dá)“依靠、依賴、指望”的含義。例如，新課標(biāo)教材模塊二第五單元有這樣兩個(gè)句子：

As some of these actors could not sing well enough, they had to rely on other musicians to help them.

因?yàn)檫@些演員中有些人唱得不是很好，他們不得不依靠隊(duì)里的其他人幫助。

The musicians were to play jokes on each other as well as play music, most of which was based loosely on the Beatles.

音樂人演奏音樂的同時(shí)還彼此打趣逗樂，這些玩音樂大多都在模仿“甲殼蟲”樂隊(duì)。

其中，rely on表示“依賴，支撐”，base on表示“以……為基礎(chǔ)”。

用“動(dòng)詞+on”表示“依靠，支撐”的短語有：
