1. depend作为不及物动词，常与介词on 或upon连用，后接名词或代词。如： The people's lives depend on their crops. You should not listen to rumor （谣言）。 You can depend on me.
2. depend 作“依靠”解，其后接“名词（代词）+ for sth.”。如： All living things depend on the sun for their growth.
3. depend作“相信”解，后接动名词或动名词复合结构。如： Susan can depend on their arriving here safely.
4. depend作“指望”解，后接“sb. + 不定式”。如： You can't depend on your enemy to help you.
5. depend 作“看„„（情况）”解，后接从句。如： It just depends on how my wife deals with the problem.
6. depend 作“信赖；相信”解，后接不定式的被动结构作定语。如： Jane is a person to be depended upon.
7. depend 在口语中意为“看情况”，可以有That depends, It depends, It all depends等几种说
法。如：
—Are you going? —It all depends.
8. depend on (upon) it 意为“请相信；没问题”，用于句首或句末。如： Do depend on it, and we shall succeed in time.
