Question

They go to work by bus .改成一般疑问句

Answer 1

Do they go to work by bus?
因为一般疑问句是指用yes（是）或no（否）来回答的句子。其结构是：系动词be/助动词/情态动词+主语+其他成分。所以是Do they go to work by bus?而不是How do they go to work? 因为后者为特殊疑问句。回答为：They go to work by bus.而不是以yes来回答的了。
不知道我这样解释清楚么？

Answer 2

Do they go to work by bus ?.
谓语动词是行为动词或者实意动词时，要在主语前加do或does,原来的动词恢复原形
