1.A是一个虚拟语气句子,it isrequired +that引导的虚拟句,(should)be,其中should可以省略.
2.A there/it seems seems to 可以看做固定的搭配,前者更倾向于翻译成为“似乎有”,后者翻译成为...似乎..
3.B 无论多么有说服力...
4.A 前否后肯.
5.D 两者之间用neither,前面已经有否定的意思了所以后面也跟着否定.
6.A句中出现除了“我”之外的人称时,不否定“我”.
7.D 可能这个句子你漏抄了什么,但是根据虚拟语句语法来讲,你的主句用了would have done,那么从句跟着往前推一个时态,只能用had done,因此选D.
8.A 这里come into being 是一个固定短语,..形成.
9.D 这里是一个非限制性定语从句,which指代前面的这个句子.
10.A 这里真正的主语是the number,为单数主语,因此相应的谓语也用单数.
写了这么多,也请你认真去体会每个句子,真正从中学到知识才好.不懂的可以继续问我.
