depend是不及物动词,不能直接接宾语
depend on加上on就可以接宾语了can i say depend on to do sth?你可以说Do sth depending on sth来表达例如I achieve this success depending on your kindly support.you are the only person i can........ the job a.depend on to do b.depend on to doing c.dependto do d.depend doing 为什么选a?you are the only person i can (depend on to do) the job.在这里depend on的宾语是person。其实意思就说I can only depend on you to do the job反观其他选项都不能表达这样的意思哦you are the only person (whom I can depend on) to do the job是一个定语从句，中间省略了whom而已。希望回答能对你有所帮助
