有如此一个句子：
The teacher said to meet at the school gate.老师说在学校门口集合。
请问句子中的said to meet at the school gate用得对不对？say to do sth如此的句式符合英语的表达习惯吗？假如可以如此用，那动词say后面接的不定式是什么成分？是宾语吗？谢谢！
▲say to do sth可理解为一种特殊的间接引语，即当直接引语为祈使句时，大家可以用ask/ tell sb to do sth，在非正式文体或非正式场所也可以简单地用say to do sth。如：
直接引语：“Stay in bed for a few days,” the doctor said to me.“卧床休息几天，”大夫说。
间接引语1、The doctor told me to stay in bed for a few days.大夫叫我卧床休息几天。（一般使用方法）
间接引语2、The doctorsaid to stayin bed for a few days.大夫说要卧床休息几天。（非正式文体）
▲类例句子：
The guidebooksays to turnleft.旅游指南上说向左转。
The recipesays to addthe flour last.菜谱上说最后加面粉。
The bosssaid to bepatient, and I’ll get a raise in due course.老板说要耐心，我会在适合的时候得到提高。
The lawyersays to doone thing, we do it; thenhesays to doit over again; he has strung out the situation for months.律师说如此做，大家就如此做，他说再重做一遍；他把整个过程拉长到几个月。
▲say后面的不定式也可以是相反的。如：
The instructionssay not to setit too high. In practice I always set it as high as possible.说明书上说不要设置得太高。但事实上，我一直设置得尽量地高。
