这两道题是专四考题,
第一题,为什么不是to do ,
独立主格结构是 with +o+oc 省略掉 with 出来的.看：
with so much homework to do,we have to stay up late.
省略掉with
so much homework to do,············
to do 表示要做,还没有发生.
doing表示正在做,和后面的句子同时发生.第一题明显是同时发生的.
第二题,
begin 一般,我说的是一般,作为不及物动词,要用及物动词,一般用start
独立主格结构中 having done 表示 已经完成,所以先于后面的发生.
with the lecture having begun,···········
肯定是先于后面的动作发生,故要用 having begun.
用having begun 把第一句和第二句的先后关系分得更清楚,
如果只是begun,语法对,但是先后关系不明确.
1 这里应该是体的概念，动词ing形式有进行体的含义，不定式有未完成体的含义。
