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. No,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 and 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、must、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，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, po
