英语语法~要理由!

a.pretty easier b.rather more difficult
2、The advertisement has been heard__three times a day.
a.to be broadcast b.broadcast
3、The patient was advised by the doctor to eat__.

第一题选a,rather 后只能加动词原形,而pretty可形容比较级
第二题选b,broadcast在这里做副词,意味经广播
第三题选b,因为a的意思是你要吃之前吃过的所有东西的一半,而b则是你平常吃的饭量的一半,food意味饭量
