几道高二英语语法题.要有详细的句型、知识点分析

1_____I had a few problems to deal with.
A Hardly have I arrived when
B Hardly did I arrive than
C Hardly had I arrived when
D Hardly had I arrived than
2 DO you have any idea _____computer plays such an important part in our daily life?
A when is it that
B how it is that
C that it is that
D what it is that
(第二句麻烦分析一下有几种复合句，怎么看的）

第一题考查部分主谓倒装,否定副词位于句首引起,答案是C. hardly...when,"一...就...."
Hardly had we begun our walk when it began to rain.我们刚一出门就下雨了.

第二题是同位语从句中考查强调句，答案是B.
抽象名词idea后接同位语从句，通过选项当中的“it is that”确定是强调句考点。
第二题是高考真题吧？

1.倒装句和时态考察。
2.同位语从句，表语从句。that it is that computer plays such an important part in our daily life。 that引导的同位语从句。that computer plays such an important part in our daily life。 that 引导的表语从句。

C hardly...when这是固定用法.意思是一...就.D 宾语从句.用陈述语序 其中还套了个强调句it is that

答案C,B但是，第二句应该写为：Do you have any idea how it is that computers play (a computer or the computer plays) such an important part in our daily life.
在国家图书馆用 “英语语法”作“主题词”查询，2004-2008年间包括《分析英语语法》在内共有650本、同期北大有118本、复旦71本、上海交大61本、清华42本，同期进入岭南大学的唯一一本中国人的“英语语法”是《分析英语语法》，在该馆用“English grammar”查询得知在此期间从世界各地购买了10本“English grammar”。2000年至今的十年间，我国出版了至少1000本“英语语法”类书籍，但唯一一本同时被香港浸会大学、岭南大学和香港中文大学购买的纸质图书只有《分析英语语法》。 国内著名语法学家近年出版的新作也没有同时让以上三家大学图书馆购买。国家教育部认定的国家级十五或十一五规划的英语语法教材没有一本是纸质资源进入香港中文大学或岭南大学。
