To make each day count! 一．现在进行时特殊疑问句式及回答 句型：特殊疑问词＋be (am, is, are)＋主语＋V-ing +其他，如： 1. What are you doing ? 2. What is he (she) doing? He (She) is riding a bike. 3. Who is singing a song ? 4. Who is swimming in the lake ? 5. What are they doing? 回答这类特殊疑问句时，根据不同的疑问词来决定回答方式。 回答What 提问时，答语是 现在进行时的肯定形式。 回答Who 提问时，只需答出 主语是谁 + 相应的be动词即可 1 .I am doing my homework. 2. He (She) is riding a bike. 3. Lucy is . 4. Jim is. 5. They are cleaning the classroom. 趁热打铁：翻译填词 1. 露西和丽丽在做什么？ 她们在跳舞。 _______ ________ Lucy and Lily ________?

To make each day count! 二．易错点 A、把动词变成现在分词形式易出错 例：1、They are swiming.(swim) 2 、Jenny is eatting breakfast. ( eat ) B、丢掉be动词, 错用be动词 或忘记把动词变成现在分词 例：1、 Look,two children flying.(fly) a kite in the park. 2 、He isn’t read ( not read) a book in bed now. 3. Tom and Jerry is listening to music now. C、对动词或动词词组提问时丢掉doing或 疑问句中 主语和be 动词位置反了。 例：1 、The students are singing in the room.(对划线部分提问) What are the students in the room? 2. The students are singing in the room . Where the students are singing? 注意：现在进行时态中对动作提问可记住此句式“What +be +主语+doing+其它?” 或简写为“What......doing......”?句式。 D、现在进行时态的选择疑问句中易忽视or后用现在分词形式 例：孩子们在跑还是在跳？ Are the children running or jump? 注意: or连接的是两个并列成分，动词形式须一致。 趁热打铁： 改错。 1. Lucy, Kate and Betty is listening to music now. 2. John is ride a horse. 3. Three people are swiming in the sea. 4. Three boys and a girl is playing football. 5. Are Mary and Rose riding horses or ride a jet-ski? 6. ( 对划线部分提问) A. Carl is fishing over there. What is Carl over there? B. Carl is fishing over there. What is fishing over there? C.

To make each day count! 三.动名词 1、动名词是一种非谓语动词形式，其结构为“动词原形+ ing”。形式上与现在分词一样，但与现在分词有很大区别。动名词既具有动词特点，又具有名词特点。在句中可作主语、宾语、表语和定语等。 Collecting stamps is one of his hobbies. 作主语 He likes watching football matches. 作宾语 My favourite sport is fishing. 作表语 He’s in the reading room. 作定语 2、一些需要掌握的动名词（用在like后的词） collecting stamps, riding a bike, diving, playing the violin, making kites 3、动名词的构成动词加ing的变化规则 与动词现在分词一致。 找出下列句子中哪些是动词的现在分词，哪些是动名词。 Tom likes reading books. He is always reading in the reading room. Jim likes playing football. He is playing on the playground now. My favourite sport is fishing ,I’m going to go fishing this afternoon. Will you go with me? 四．动词的过去式． 一般过去时表示过去某个时间发生的动作或存在的状态，常和表示过去的时间状语连用。一般过去时也表示过去经常或反复发生的动作。 动词过去式变化规则： 1．一般在动词末尾加-ed，如：play-played, cook-cooked 2．结尾是e加d，如：taste-tasted 3．末尾只有一个元音字母和一个辅音字母的重读闭音节，应双写末尾的辅音字母，再加-ed，如：stop-stopped 4．以“辅音字母+y”结尾的，变y为i， 再加-ed，如：study-studied 5．小学常用不规则动词过去式： am,is-was, are-were, do-did, see-saw, say-said, give-gave, get-got, go-went, come-came, have-had, eat-ate, take-took, run-ran, sing-sang, put-put, make-made, read-read, write-wrote, draw-drew, drink-drank, fly-flew, ride-rode, speak-spoke, sweep-swept, swim-swam, sit-sat Where there is a will,there is a way. 4
