25、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 就是我们平时上课时说的动词,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,具体判断方法如下: 有,就加ing 读句子读该单词认识该单词理解意思看有无be动词 (若是be going to 就用原形) 没有,再看情态动词 有,就用原形 有,就加ed 没有,再看有无表示过去的时间状语 是第三人称单数就加s或es 没有,再看主语 不是第三人称单数就用原形 (2)be动词 a、Am-was Is -was Are-were 口诀:
26、我用am, 你用are, is用在他她它,所有复数全用are。 5 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 arent. Are they American? Yes, they are. No, they arent. Is the cat fat? Yes, it is. N
27、o, it isnt. 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。 判断步骤: 第一、三人称单数,就用was 有,再看人称 第二人称单数和所有复数,就用were 看有无表示过去的时间状语 第一人称单数,就用am 没有,再看人称第三人称单数,就有is 第二人称单数和所有复数,就用are 用am, is, are 填空 1. I _ a boy. _ you a boy? No, I _ not. 2. The girl_ Jacks sister. 3. The dog _ tall a
28、nd fat. 4. The man with big eyes _ a teacher. 5. _ your brother in the classroom? 6. Where _ your mother? She _ at home. 7. How _ your father? 8. Mike and Liu Tao _ at school. 9. Whose dress _ this? 10. Whose socks _ they? (3)情态动词 情态动词也是一类特殊的动词,平时我们不把它说成是动词。情态动词可以和行为动词同时出现在同一个句子中。 我们现在学过的情态动词有:can、m
29、ust、should、would、may。接触最多的是can。 情态动词后动词总是用原形。(不受其他任何条件影响) 2、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
30、,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-f
31、ish, people-people, Chinese-Chinese, Japanese-Japanese 判断步骤: 如是am、is或was原形 读句子读该单词认识该单词理解意思看be动词 如是are或were加s或es 3、形容词(包括副词) 6 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+er。 两个重要特征:asas中间一定用原形,有than的时候一定+er。 4、人称代词和物主代词 主格 you I he she it we they 宾格 形容词性物主代词 名词性物主代词 第一人称 I me
32、we us my mine our ours 第二人称 you you you you your yours your yours 第三人称 he him they them his his their theirs she her her her sit it its its 人称代词:有主格和宾格之分。一般动词前用主格,动词后用宾格。 物主代词:有两类:形容词性物主代词(短的)和名词性物主代词(长的) 一般看后面有没有名词,如有,就用形容词性物主代词(短的);如无,就用名词性物主代词(长的)。 用所给词的适当形式填空 1. That is not _ kite. That kite is
33、very small, but _ is very big. ( I ) 2. The dress is _. Give it to _. ( she ) 3. Is this _ watch? (you) No, its not _ . ( I ) 4. _ is my brother. _ name is Jack. Look! Those stamps are _. ( he ) 5、数量词 我们学过两类:基数词和序数词。基数用于表示数量多少,而基数词用于表示次序,常在日期中出现。 6、冠词 有a、an、the。a和an有具体的意思,一(个),the没有具体意思,有时翻译为这、那。确定用a、an还是the时可根据汉语意思。a和an的区别:an用于元音音素(一般就是元音字母aeiou)前,a用于辅音音素前。 7
