much as非常像
much as a regiment of soldiers wouldif a tree stood in their road这句中的would if不是一个意群的,应该在would后有一个停顿,实际是在would后省略掉了do.整个句子是说：非常像一队战士遇到前方路上有一棵树的时候会做出的反应一样.什么情况下可以省略do,具体The curiosity of the wise,who wonder at all the great things and try to find out all they ___ about them.（此句中）A.know B.study C.must D.can当时此处选D，那么能否以这两题为例，详谈下什么情况下省略do。不然有些选起来意思不通你最熟悉的应该就是“We should do what we can (do) to help them". 应该说如果主句中有一个动词，从句中如果再次提到这个动词而且这时有助动词（would , can ,must, may, should等）时，就可省掉前面的那个动词The curiosity of the wise,who wonder at all the great things and try to find out all they can(do) about them.此句主句没do啊 much as a regiment of soldiers would(do) if a tree stood in their road此句主句也没do啊真正考的肯定是不易发现的啊主句是they divide right and left and reunite after passingeach column，这里的do就是代表divide right and left and reunite after passing，而且并不一定是Do，可以是任何动词。The curiosity of the wise,who wonder at all the great things and try to find out all they can(do) about them.这句的主句动词是find out且这时有助动词（would , can ,must, may, should等） 纠正你一个笔误，这些词是modal v.而非aux.v.也是助动词
