请认真详细回答为什么,不要敷衍了事,否则不但不追加分,不会的人请不要乱回答!

1.A,这是个强调句,it is ...that句型,强调的是状语in 1969.看一个句子是不是强调句可以把it is that这三个词去掉,看剩下的部分是不是完整句子,如果是,那这句话就是强调句.
2.C 这句话还是强调句,第二个空seperate from是固定词组,从.分离
3.A there be 句型
4.B such是形容词,后面跟名词such a fool,而so是副词,修饰形容词、副词,这句话如果非要用so,就得变成so foolish.As he looks意为像他看上去那样,这里不能用被动语态,这就相当于he looks foolish一样,不是被动.
5.B 像这样this is the first开头的句子,要接完成时
6.of much help是一个形容词词组,意思是：这里的引导词which代的是逗号前的整句话.
7.这里并不能因为有look forward to而选C,这是一个定语从句,其中we looked forward to修饰的是主语the great day.把这句话简化一下,就变成The great day came at last.
