（1）加可数名词单数，注意要先加形容词再加不定冠词。如

2、若涉及数量或程度，可用“as much+不可数名词+as”和“as many+可数名词复数+as”。如：He doesn’t pay as much tax as we do / as us. 他没我们交的税款多。There are not as many restaurants as there were. 现在餐馆没有过去多了。
3、其间接形容词时，有时该形容词还可修饰另一名词，但这个名词应带有不定冠词(注意词序。如：I have as good a voice as you. 我的声音和你一样好。

1、as well as后面不能跟完整的句子。as well as 可连接并列的单词或短语。例如： It is unpleasant in summer as well as in winter. 夏天不好过，冬天也不好过。
2、as well as 连接两个谓语动词时，它们的时态应保持一致。例如： He publishes as well as prints his own books. 他的书是他自己印刷出版的。
3、as well as 与动词连用时，其后可用V-ing形式，尤其as well as 位于句首时，此时相当于in addition to。例如： As well as breaking his leg, he hurt his arm. 他不但摔断了腿，而且还伤了胳膊。
4、如果as well as 前面是动词不定式，那么其后的动词也是不定式，但to要省略。例如： You cannot expect her to do the housework as well as look after the children. 你不可能叫她既照顾孩子又做家务。
5、由as well as 连接的复合主语并不影响谓语动词的数。例如：Helen as well as I is eager to see the performance. 海伦和我一样急于要看演出。
6、as well as 连接的人称代词既可以是主格也可以是宾格，但句意不同。例如： They have invited you as well as me. 他们邀请了我，也邀请了你。（you和me都作invited的宾语）。
7、as well as 用于肯定结构和否定结构中，其意义不同。as well as 和not搭配使用，as well as 位于not前时，两者均否定；位于not后时，否定前者，肯定后者。例如：（1）George, as well as his brother, has gone abroad. 乔治和他兄弟一样都出国了。 （2）George hasn”t gone abroad as well as his brother. 乔治并没有和他兄弟一样出国去。（他兄弟一人出国） （3）George, as well as his brother, hasn”t gone abroad. 乔治和他兄弟都没有出国。
8、as well as 在意义上通常强调前者，而not only …but also在意义上则强调后者。
