not to 和 don't 的区别.We are often warned,by our teacher,______waster precious time because time will never return.为什么这里要用not to 而不用don't
谓语动词是实意动词时,用don't 对谓语进行否定;
而该句中并非是对谓语的否定,而是对不定式的否定.
分析:by our teacher 是插入语,没插入时是:we are often warned to waste precious time,
对不定式to waste 进行否定,直接在不定式前加not,就成了:
we are often warned not to waste precious time.
加入插入语就成了原句的情况:we are often warned,by our teacher,not to waste precious time.
前面是动词的时候用not to ,本句前面是warn后面就要跟not to
don't前面要么是主语,要么是祈使句,直接以don‘t开头
