prevent sb doing sth 还是prevent sb from doing sth?Ellen would prefer going to the theater more frequently,but her schedule prevents her attending at more than one play a month.错误处是attending 英语

【答案】 prevent sb (from) doing sth 其中from可要可不要的,但在相同意思的同类短语keep sb from doing sth 中,from 就不可以省这句改错改的是attending,是因为attend 本身就是一个及物动词,后面不需要再跟介词at,所以应该改为其他意为“参加”的及物动词
