同上

I have to(look after) my grandma at home.用括号中单词的正确形式填空The doctor arrived (in time ) and saved him.同上
have to 的意思是不得不 其后接动词原形 这是固定用法
所以:I have to look after my grandma at home.
in time 意思是及时
The doctor arrived in time and saved him.
意思是:医生及时赶到,救了他

I have to look after my grandma at home.
to后面跟动词原形,所以填原形就行了
The doctor arrived and saved him in time.
应该是这样吧,这题我也不确定

look after考查(have to do sth)
in time(及时之意)

have to + 动词原形
look after

i have to look after my grandma at home.
have to do sth 不得不做什么事,必须得做什么。
the doctor arrived in time and saved him.

look after
in time
