英语句子Except for Jenny,everybody admires him for his great sen

1.except与except for有时可以通用,不过,一般情况下,except for可置于句首,而except则不能.如：
Everyone is here except Tom.(或：Except for Tom everyone is here.)除汤姆外,大家都到了.
2.except与except for在句中也可互换.
一般来说,否定句中用except,肯定句式可以用except for来替换.如：
This article has no blunders except a few mistakes.这篇文章除了一点小错外没有大错.
此句可改为：This article is instructive except for a few blunders.这篇文章除了有些错误外,是有教育意义的.
不过,在前后有相称的同类词语时,应用except,否则用except for.如：
We come to school every day except Sunday.除星期天外,我们天天上学.(句中every day与Sunday同类)
This dress is ready except for the buttons.衣服做好了,只是钮扣未缝上.(句中ready与buttons不同类)
