Question

一道英语语法题,37.John may phone tonight.I don't want to go out ___？

Answer 1

in case作短语连词,能引导状语从句.就其词义和语法职能来分,可引导两种从句.
其一：in case ／just in case引导目的状语从句作“以免,以备,以防”等解.如：
He takes a torch in case it gets dark before he returns．
他带了手电筒,以备天黑以后回家之用.
I've bought a chicken in case your mother stays to lunch．
我买来一只童子鸡,以备你妈妈留下吃午饭.
I decided to stay at home just in case my friends came round．
我决定留在家里,以防朋友们不期而至.
I'll make some sandwiches in case you feel hungry on the journey．
我会做些三明治,免得你在旅途中饿着.
Buy one of his paintings now,in case they get more expensive．
现在就买下他的一幅画,以防他的画涨价.
You must be quiet in case the fish are frightened．
选C的,7,as long as 引导时间状语从句，表示“只要, 如果”，
in order that 引导目的状语从句，一般用在虚拟语气，
in case 引导条件状语从句，表示“万一”，
so that 引导目的状语从句，表示“以便；为了”，
体会一下相比较还是D更符合要求,1,一道英语语法题,
