..50分
1._______,he sat up late preparing the opening speech for Auto Shanghai 2007.
A.as he was tired B.tired though was he C.tired as he was D.it is because he was tired
2.his interest is flying.when studying at Yale University,he _____ set up the Yale Fying club
A.has helped B.had helped C.helped D.was helping
请说明原因,

1.c
as的前置强调: 虽然他很累了
2.a
主句是一般现在时,所以下面的那句应该时与现在时态 有一定关系的时态:他已经在耶鲁飞行俱乐部你出了一份力

C - a

1. C Tired as he was = Even though he was tired.
2. C 一般过去时...

1 选 c
tired as he was 意思是 尽管他很累
2 选 a
前半句is 是现在式 后半句只是表示已完成的事情.
如果前半句换成 was 那后半句就要选 B had helped 是为了前后一致.

1.虽然他很疲劳了,但仍熬夜赶写2007年上海汽车展开幕式上的演话稿.
答案:C.tired as he was
2.他的兴趣是飞行.他在耶鲁大学读书期间,他帮助建立了耶鲁飞行俱乐部.
答案:C.helped
这里时态要保持一致,因为是在耶鲁读大学期间,过去时态,所以后面的help也要用过去时态,尽管前面说的是他的爱好为一般现在时态
