besides,except和as well as的区别和dare的用法

解题思路： 本题是一个难点，也是常考点。记住它们的用法，常练习即可。加油。
解题过程：
except和besides都可解作“除……之外”但含义不同。
except表示“从所提到的人或事物中除去，即从整体中除去一部分”，表示递减的概念，含义是否定的。besides表示“除了……之外，还有……”，指“在整体中加入一部分”，表示递加的概念，含义是肯定的。
试比较：
①We all went except him.
除他之外，我们都去了。(他没有去)
②We all went besides him.
除他之外，我们大家也都去了。(他也去了)
(1)besides常与other／more／else等词连用except常与all／every／everyone／none／nobody／everything／nothing等总括词连用。
eg. He had other people to take care of besidesme.
All the students in Class One went to the cinema except Li Ping.
(2)若句中没有实义动词do的某种形式except后接动词不定式而besides后接动词的-ing形式。
eg.I had no choice except to obey／besides obeying his order.
(3)若句中有实义动词do的某种形式二者后面都可以接动词原形。
eg.She has nothing to do except／besides go with him.
(4)二者后面都可以接从句。
eg.①Besides that he explained the theoryhe gave us some examples.
②He is a good student except that he sometimes comes late to school.
(5)except后面可接for(构成短语except for)或其他介词短语，而besides不能。
as well as意思是也，表示两者都是，如He as well as his father likes playing basketball.
他和他的父亲都喜欢打篮球。
as well as besides, , excep用就远一致原则，也就是跟第一个主语一致。例如：I as well as my parents am fond of music.
Dare 的用法
dare 可做情态动词也可做实义动词 １．Dare作情态动词时，主要用于疑问句、否定句和条件从句中，一般不用在肯定句中。如： How dare you say I'm unfair. He daren't speak English before such a crowd, dare he?
２．dare也常用作实义动词，有时态、人称和数的变化，所不同的是，作实义动词时，在肯定句中，dare后面通常接带to的不定式，在否定和疑问句中，dare后面可接带to或不带to的不定式。如： I dare to swim across this river. He does not dare (to) answer. Don't you dare (to) touch it! I wondered he dare (to) say that. He needs to finish it this evening.
３．dare not to 中dare为情态动词．don't/doesn't/didn't dare to中dare是实意动词．don't用在第一人称第二人称现在式中．doesn't用在第三人称现在式．didn't用在过去式中．
1.应是except. except表示“从所提到的人或事物中除去，即从整体中除去一部分”，表示递减的概念，含义是否定的。except常与all／every／everyone／none／nobody／everything／nothing等总括词连用。
2.dare此时用作实义动词。所以用了过去式。
