高中英语情态动词,虚拟语气题（2题）
1.He seldom listens to others.He _____ answer for what he has done.
A shall B will C can D would
2.If only I _____ how to operate a computer as you do!
A had known B would know C should know D knew
请给出相应语法知识的解释,
答
1A shall与he，she，they，you，it等连用时表示必须，必定,整句话的意思是，他很少听被人的话。他绝不会对他说的话负责。这里第三人称的he 与shall连用表达说话人对他的一种情感评论，故用shall.
2D 与现在事实 as you do相反所以要用一般过去式表虚拟语气。全局意思是 要是我有你那么懂得怎么操作电脑那该多好啊。
答
1.A
他很少听别人的话.他应该对他所做的负责.
-answer for对...负责,承受...的后果；
-shall与he,she,they,you,it等连用时表示必须,必定的意思,
例：You shall not get away with this.你绝不可以把这东西带走.
2.D
如果我像你一样懂怎么操作电脑该有多好.
-if only要是...多好,要用虚拟语气；
-此句没有“过去的过去”的意思,用一般过去时就可以了.
