decide具有及物动词和不及物动词的用法，其后常接两种形式，具体如下：
1. 表示“决定做某事”，其后要接不定式，不能接动名词。如：

若要接动名词，应先接介词 on（但不如用不定式结构常见）。如：

另外，decide on之后还可接名词或代词，表示“对……作出决定”或“选定……”。如：

After seeing all the candidates we’ve decided on this one. 我们见了所有的候选人，决定选这位。
2. 表示“决定不做某事”，可用 decide not to do 或 decide against doing。如：
He decide not to change [against changing] his job. 他决定不换工作。
They have decided not to move [against moving] to London. 他们已决定不搬到伦敦去。
另外，decide against 之后也可接名词或代词。如：
After talking the matter over, they decided against the plan. 经过反复讨论，他们决定不采用该计划。
