英语语法改错（ ）41.What do you usually do to congratulate your birt

41.D congratulate → celebrate
congratulate的宾语必须是sb,结构：congratulate sb on doing sth；
celebrate的宾语才是sth.
42.C third → three 或 D weeks → week
表示“每隔...”的结构为：every + 基数词 + 名词（复数）= every + 序数词 + 名词单数
43.B are → is
此句的主语根据句意为单数,所以谓语动词用三单is
44.B how → what
结构what to do next中,do缺少宾语,所以用代词what,而不能用副词how
45.done → to do 或 undone
根据句意,so many things be done这个动作尚未发生（即这么多事情还没有做）,所以用不定式或undone.
46.attend → attend to
被修饰词something和做后置定语的to attend之间无法连接,必须加上to,即attend to something important“处理一些重要的事情”
47.D should be → was
suggest此处意思是“表明/暗示”,其宾语从句用陈述语气并非虚拟语气,所以从句谓语用was
48.D have → had
see it发生在didn't go to the film之前,为“过去的过去”,所以原因状语从句采用过去完成时
49.A major → majored
根据后面从句的时态,主句也必须采用一般过去时
50.another → other
此处another本身就表示单数“另外一个”,不能和any直接连用.
any other student意思是“其他的任何一个学生”.
