形容词可数名词（单数名词，复数名词）序数词副词不定式
形容词：简称adj.或a，形容词用来修饰名词或代词，表示人或事物的性质、状态，和特征的程度好坏与否，形容词在句中作定语，表语，宾语补足语。她是一个好学生，她学习努力。She is a good student, and she works hard.这辆自行车很贵。This bike is expensive.对不起,我现在很忙。I am sorry, I'm busy now.你为这次会议做好准备了吗? Have you got everything ready for the meeting?形容词的语法功能：一、作定语He is the greatest writer alive.他是依然健在的伟大的作家。Somewone else has done it.别人已经做了这事。二、作补语形容词做主语补足语和宾语补足语时,可以表示其现状、状态，也可以表示某一动作的结果，并常用在表示“认为，看待”的动词如believe，prove，consider等候。例如：The news made her sad.这消息使他感到非常悲伤。Don't marry young.不要早婚。三、作状语形容词或形容词短语可作状语，形容词作状语时，可以看作是“being+形容词”结构的省略，可表示时间、原因、条件、方式、强调或伴随状况等意义。例如：Enthusiastic，they are co-operative.热心的时候他们是很合作的。Rich or poor, young or old, we all have problems.不管是穷人还是富人，不管是年轻人还是老人，我们都有问题。四、做表语The ship was adrift on unknown seas．那艘船在陌生的海域漂流。五、做主语Old and young joined the discussion.Rich or poor meant the same to him.作感叹语Very good!Say it again.Stupid!He must be crasy.形容词的几个特殊用法：most 同形容词连用而不用 the, 表示 " 极,很,非常, 十分"。 It's most dangerous to be here. 在这儿太危险。 I cannot do it, it's most difficult. 我干不了这件事，太难了。 "The+形容词比较级..., the+形容词比较级..." 表示 " 越... 就越..."。 The more you study, the more you know. 你学的越多, 就知道的越多。 The more I have, the more I want. 我越有就越想要有。 The more, the better. 越多越好。 " 形容词比较级 + and + 形容词比较级 ", 表示 " 越来越...

Y say what you like. 副词有加a或ly的 区别在于通常加a 的副词描述一种状态，而加ly 的副词则倾向于感觉。 动词不定式：指由to加上动词原形（而且只能是动词原形）所构成的一种非限定性动词，但在有些情况下to可以省略。动词不定式在语法功能上可作主语、宾语、宾语补足语、表语、定语和状语。动词不定式可以作以上各种成分，但它毕竟是动词，所以有动词的属性。动词不定式及其短语还可以有自己的宾语、状语，虽然动词不定式在语法上没有表面上的直接主语，但它表达的意义是动作，这一动作一定由使动者发出。这一使动者我们称之为逻辑主语，其形式如下：
(not) to do
(not)&to be done
(not) to have done
(not) to have been done
(not) to be doing
完成进行式
(not) to have been doing
&不定式的用法:1、不定式作主语 例如：To remember this is very important. 注意：为了避免头重脚轻，在许多情况下，通常都将作主语的不定式置于句子后部，而在句首主语位置使用形式主语it。 例如：It is very important to remember this. 2、不定式作表语例如：He seems to be ill. 注意：不定式作表语主要有三种情况，一是用于seem, appear, prove等系动词之后的不 定式（尤其是to be），二是像My job is to sweep the floor. 这样的主语与表语“等价”的情形，三是表示想法、约定、义务、命令、可能性、命运等，如：&You are to come when I call. 3、不定式作宾语 例如：I can not afford to buy a car. 注意：①不定式不仅用作动词的宾语，还可用作个别介词（but, except）的宾语。 例如：I had no choice but to wait. ②当作宾语的不定式后跟有宾语补足语时，通常要用形式宾语it代替不定式，并将真正的宾语不定式置于宾语补足语之后 例如：I find it difficult to learn Japanese well. 4、不定式作宾语补足语 例如：Who taught you to drive? 5、不定式作定语 例如：I have a question to ask you. 注意：有的名词（如way, chance, right等）后用作不定式可换成of doing sth. 如：It is the best way to do (of doing) it. 但是以下名词后接不定式作定语时通常不能换成of doing sth. attempt& courage& decision& effort& fortune& failure& invitation& wish 6、不定式作状语 例如：I went to France to learn French.
