英语判断词性的方法：
判断名词
名词一般充当主语、宾语或表语。常见结构为：
结构1：冠词+_______。

判断动词
动词可充当任何成分：动词一般作谓语，其分词结构和不定式结构可作主语、宾语、定语、状语或补语。常见结构为：

In the early 1990s, the word “Internet” was strange to most people. But today, Internet has become a useful tool for people all over the world. Maybe Internet has been the greatest invention in the field of communication in the history of mankind(人类).
Communicating with others on the Internet is much faster. We can chat with a person who is sitting in the other part of the world. We can e-mail our friends and they can read the e-mails within a minute.
Giving all kinds of information is probably the biggest advantage of the Internet. We can use search engines to find the information we need. Just type in a keyword or keywords and the search engine will give us a list of suitable websites to look at.
We can enjoy a lot on the Internet by downloading games, visiting chat rooms or surfing (浏览)websites. There are some games for free. We can meet new and interesting people in the chat now. We can also listen to music and see films.

2.由名词后的动词单数或复数(即主谓一致): The _____ (建议) are reasonable and some of us will accept them.

英语判断词性的方法：
先说名词
由动词派生的名词
1动作名词(传统语法归为抽象名词)-tion -ment -al -ure -ance -age
比如admiration competation preference assistance exposure refusal payment
2动作者名词(这个你应该比较清楚)-er -or -ar -ee
3动名词(这个很普遍,已经进入语法概念) -ing 由形容词派生的名词
1-ness, goodness illness happiness greatness
2-ity,purity ability possibility
3-th, depth width warmth
4-ence, silence patience excellence 5-dom, freedom boredom wisdom
由名词派生的名词(虽然词性没变,但也是派生的一部分,只是提下吧)
下面是动词
这个我记的不多,我一般是以动词作为单词的原貌去记,如果再分解前后缀,我就觉得陌生了.
前缀 mis-表示坏,错误,否定的前缀,在元音前; dis- 分开 分离 否定 in- 否定 与…相反;
re- 又 再 ……比如reread misuse dislike 后缀
1-ate -ute altenate communicate attribute
2-en darken thicken widen harden fasten lessen redden 都是变什么什么
3-ify -efy 意思是使之什么什么化 purify simplify beautify rarefy
4-ize -yze(英英用ise yse) modernize analyze
5-ish abolish banish vanish
6-er remember whisper glitter transfer
形容词这个比较多,也比较灵活
1-able -ible 加在及物动词后,一般是可什么什么的 比如 eatable可以吃的 audible可听见的
2-al 表示 属于…/有什么什么属性 natural cultural national global
3-ate 表示性质状态 fortunate coordinate
4-en 加在物质名词上. golden wooden earthen
5-ful 加在动词,名词上 意为 充满 beautiful hopeful useful joyful
6-ic -ical这两种后缀的区别似乎高中要考,你可以翻词典,记下 historic historical electric electrical economic economical philosophic philosophical
7-ish 用于国家 民族专有名词后,用在普通名词后有轻蔑意味 British English Spanish Irish childish foolish girlish selfish boyish
8-less 表示没有 homeless colorless hopeless careless
9-like childlike manlike motherlike womanlike ladylike
10-ly 有….性质(这个后缀很多是副词,是形容词是少数)friendly childly manly motherly
11-ous 表示充满 dangerous courageous famous continuous
12-some 表示引起 bothersome troublesome handsome middlesome
13-y 表示多 windy frosty rainy snowy sunny funny muddy icy
14-ive -ative 表示有…..倾向 active progressive imaginative comprehensive
15-etic表示性质 energetic synthetic poetic magnetic
16-ant -ent pleasant tolerant different
17-ary -ory 表示 ….的 contrary elementary preparatory
18-id 表示性质 acid liquid humid florid splendid horrid
19-ed 名词后,加在动词后是另一回事aged skilled talented cultured gifted 20-ing -ed 动词后 分词作形容词 interesting amazing amazed interested
英语中的词性判断：
一、词性的分类
词类又叫词性，英语单词根据其在句子中的功用，可以分成十个大类。
1.名词 noun n. student 学生
2.代词 pronoun pron. you 你
3.形容词 adjective adj. happy 高兴的
4.副词 adverb adv. quickly 迅速地
5.动词 verb v. cut 砍、割
6.数词 numeral num. three 三
7.冠词 article art. a 一个
8.介词 preposition prep. at 在…
9.连词 conjunction conj. and 和
10.感叹词 interjection interj. oh 哦
前六类叫实词，后四类叫虚词。
二、代词
代词pronoun简称pron是代替名词的一种词类。大多数代词具有名词和形容词的功能。英语中的代词，按其意义、特征及在句中的作用分为：人称代词、物主代词、指示代词、反身代词、相互代词、疑问代词、关系代词、连接代词和不定代词九种
人称代词的用法：
I saw her with them， at least， I thought it was her.
我看到她和他们在一起，至少我认为是她。(her做宾语，them做介词宾语，her作主补)
a. — Who broke the vase?–谁打碎了花瓶?
b. — Me.–我。(me作主语补语= It’s me.)
并列人称代词的排列顺序
1) 单数人称代词并列作主语时，其顺序为：
第二人称 -> 第三人称 -> 第一人称you -> he/she; it -> I
2) 复数人称代词作主语时，其顺序为：
第一人称 -> 第二人称 -> 第三人称we->you ->They
