01 词类 动词、名词和形容词不太容易区分,如不能一眼看出,可用如下方法:先用“一(量词)” (如:一个、一张等)和这个词连起来说,如说得通,一般认为是名词;说不通再用“很”去判断,就是把“很”和为个词连起来说,说得通一般就是形容词;都说不通就是动词。 (目前我们学过的,以后可能不同)(另外一些很明显的,如人称代词、数词、情态动词等一下就可以知道) 动词 这里所说的动词是指各种动词总称,其中包括行为动词(就是我们平时总说的那种动词)、be动词、情态动词。 (1) 行为动词就是我们平时说的动词,表示某一动作或行为。 如:sweep、live等。行为动词我们已学过它们的四种形式:原形、+s/es、+ed、+ing, (2) be动词a、Am--was Is --was Are--were口诀:我用am,你用are, is用在他她它,所有复数全用are。 b、肯定和否定句 I am (not) from London.  He is(not) a teacher.  She is(not) in the dining room.  My hair is(not) long. Her eyes are(not) small. c、一般疑问句  Am I a Chinese? Yes, you are. No, you aren’t.  Are they American? Yes, they are. No, they aren’t.  Is the cat fat? Yes, it is. No, it isn’t. 我们现在学过的be动词大致分两类:is、am、are为一类,一般用于一般现在时、现在进行时和一般将来时中,was和were为另一类,一般用于一般过去时。 名词 表示某一事物,有具体的和抽象的之分。 判断的关键词往往是be动词,be动词如果是am、is或was,名词就用原形;be动词如果是are或were,名词就加s或es。 这里强调两点 不可数名词都默认为单数,所以总是用is或者was; 最好不要根据some、any、a lot of等词去作判断,以免受误导。 如何加后缀 a. 一般情况下,直接加-s,如:book-books, bag-bags, cat-cats, bed-beds b. 以s. x. sh. ch结尾,加-es,如:bus-buses, box-boxes, brush- brushes, watch-watches c. 以“辅音字母+y”结尾,变y为i,再加-es,如:family-families, strawberry-strawberries d. 以“f或fe”结尾,变f或fe为v,再加-es,如:knife-knives e.不规则名词复数 man-men, woman-women, policeman-policemen, policewoman-policewomen, mouse-mice child-children foot-feet ,.tooth-teeth fish-fish, people-people, Chinese-Chinese, Japanese-Japanese 形容词(包括副词) 形容词表示某一事物或的特征,副词表示某一动作的特征。 形容词和副词只有两种形式:原形和+er。 未作比较的情况下就用原形,比较时就+
