请教两个语法点

木川

OG102题
Except for a concert performance that the composer himself staged in 1911, Scott Joplin's ragtime opera Treemonisha was not produced until ............
正确答案就是A。而答案E将except for 换成了excepting, 请问两者的区别？

OG112题
Domestic automobile manufactures have invested millions of dollars into reaserch to develop cars more gasoline-effecient even than presently on the road.
答案是
Domestic automobile manufactures have invested millions of dollars in reaserch to develop cars even more gasoline-effecient than those at present on the road.
请问presently 和 at present 在这里用法的区别。

谢谢

excepting 的逻辑主语为Scott Joplin's ragtime opera Treemonisha ，在这里有点说不通，一般except 作为动词的用法有except for  和except that，作为介词用except.

第2题主要考察是比较对象一致，presently 和 at present 在意思上应无明显区别。

请各位NN指正。

我跟你的看法好像刚刚相反。
我觉得except 做介词的时候，应该是except for,而做动词的时候是except......查了字典，except可以做动词，也可做介词。

presently 和at present肯定有区别，不然ETS绝对不会改。

谢谢

１。except/except for 区别不用管词性，看后面排除的的东西是否是与主语一类，不一类都用except FOR
２。确实没有区别吧。

EXCEPT FOR 用于不同类事物比较；EXCEPT用于同类事物
注：白勇语法解说

“presently 和at present肯定有区别，不然ETS绝对不会改。”
似乎没碰到把他们作为烤电的语法题。
