连词是连接字、短语、从句与句子的词,是虚词,因此它不能独立担任句子成分。连词主要分为两大类:并列连词和从属连词。并列连词用来连接并列关系的词、词组或分句。它包括:and,or,but,so,for,both…and,either…or,neither…nor,not only…but also。
从属连词用来引导从句,它包括: that, when, till, until, after, before, since,because,if,whether,though,although,so…that,so that,in order that,as soon as
并列连词用来连接具有并列关系的词,短语或句子。常见的并列连词有:
(1)表并列关系的and, both…and, not only…but also, neither…nor等。
(2)表选择关系的or, either…or等。
(3)表转折关系的but, while等。
(4)表因果关系的for, so等。
1.句型:(1)How+形容词/副词+陈述句(主语+谓语)

(2)How+陈述句(主语+谓语)
How he loves his son!
(3)How+形容词+a/an+单数可数名词+陈述句(主语+谓语)

上述两种感叹句可以互相转换。例如:
What a clever boy he is!→How clever the boy is!
What a cold day it is!→How cold it is!
①不定冠词—般放在所修饰的单数可数名词前。
eg, a bike, an egg
②当名词被such, what, many修饰时,不定冠词放在这些词之后。
eg.It took me half an hour to finish my homework.
He left in such a hurry that he forgot to close the door.
What a dangerous job it is!
Many a man has gone to the big cities for work.
③当名词前的形容词前有so, how, too等词时,不定冠词应放在形容词之后。
Eg. She was so nice a girl that she took the blind man to the station.
How nice a film this is!
