4、h , a little, a lot 在句中修饰动词，作状语。例如：I like swimming very much/a lot. 我非常喜欢游泳。Thanks a lot/very much. 非常感谢。very much 一般只修饰如 like, love和 want这样表示情感的动词，不修饰其他动词。例如： We want to see her very much. 我们非常想见到她。a little和a lot在句中还可作宾语，而very much那么不能。例如：I drink a lot, but she drinks a little. 我喝得挺多，而她只喝了一点儿。She r
5、eads a lot, so she knows much. 她读书很多，所以她懂得也很多。a little还可修饰不可数名词，表示“一点儿。例如：Id like a little milk. 我想喝点牛奶。2notat all表示完全否认，意为“根本不或“一点都不，是为了加重语气，一般放在句尾。例如：She cant cook at all. 她一点儿也不会做饭。I cant see it at all. 我一点也看不见那东西。not at all作为一个固定词组可用来表示“不用谢或“没关系。例如：Thank you very much. 非常感谢。Not at all. 不用谢。2. 主语
6、为第三人称单数时一般现在时的结构肯定式：主语+谓语动词的第三人称单数+其他。例如：He likes bananas a lot. 他非常喜欢吃香蕉。It looks like a cat. 它看上去像只猫。否认式：主语+助动词doesnt+动词原形。例如：She doesnt like milk. 她不喜欢喝牛奶。He doesnt like eggs at all. 他一点儿也不喜欢鸡蛋。疑问式：助动词Does+主语+动词原形。肯定答复：Yes，主语+does. 否认答复：No，主语+doesnt.例如： Does Kate like meat? 凯特喜欢吃肉吗？Yes, she does.
7、 是的，她喜欢。No, she doesnt. 不，她不喜欢。3. 动词第三人称单数词尾变化形式及读音动词第三人称单数词尾变化一般有三种形式：1大多数在词尾加-s，-s在清辅音后读清辅音s，在浊辅音及元音后读浊辅音z。例如：helphelps helps makemakes meiksrideridesraidz knowknowsnuz2以字母s，x，ch，sh或o结尾的动词加-es读iz。例如：guessguessesgesiz fixfixesfiksizteachteachesti:iz washwashesgogoes3以辅音字母+y结尾的动词，先变y为i，再加es，读z。例如：fl
8、yfliesflaiz carrycarrieskriz动词如play，say等不属于这一范畴，因字母y前不是辅音字母，而是元音字母，这样的动词构成第三人称单数时直接加-s。4. Many people in the restaurant know him very well. 饭馆里的许多人都非常熟悉他。短语know sb. well意为“熟悉某人。例如：Mr Smith is my friend.I know him very well.史密斯先生是我的朋友，我非常了解他。5. Do you like swimming? 你喜欢游泳吗？1短语 like doing sth. 意为“喜欢做某
9、事，doing在这里是动名词，做动词 like的宾语。动名词是由“动词原形+-ing构成。其构成规那么与动词的现在分词构成规那么相同。例如：He likes watching TV. 他喜欢看电视。Do you like flying kites? 你喜欢放风筝吗？2动词like后面还可接动词不定式，在意义上动名词和不定式没有什么区别，例如：Why do you like to eat here? 你为什么喜欢在这儿吃饭？Jim likes to read books. 吉姆喜欢读书。3动词like后面还可接动词不定式做宾语补足语，即短语like sb. to do sth.，动词不定式是宾语
10、sb.的补足语。like在这里意思上接近于“希望。例如：Our English teacher likes us to read English in the morning.6. make和 do1这两个词都可解释为“做，但意义不同。make指做东西或创造东西，即做出来或造出来一个原来没有或不存在的东西。例如：Can you make a kite for me? 你能给我做一个风筝吗？2do指做一件具体的事情。例如：Lets do something. Lets not play all day. 我们还是做些什么事吧，不要整天玩。7. He wants to ride the machi

Why does he have to wash the dishes? 为什么他不得不洗碗？短语 have to do sth. 意为“必须做某事或“不得不做某事。例如：Do you have to go now? 你现在必须走吗？You d
12、ont have to go. You can stay here. 你不必走，你可以留在这里。9. and, or和 butand, or和but都是连词，在句中连接两个或两个以上并列成分，如连接两个词，连接两个短语，或连接两个分句。所连接的两个成分必须一致。1and意为“和，表示前后两成分之间的并列关系。例如：My uncle likes meat and rice very much. 我叔叔非常喜欢吃肉和米饭。2or意为“或者“或否那么，表示前后两成分之间的并列或选择关系。例如：Do you like milk or bread? 你喜欢牛奶还是面包？Lets help him, or
13、 he cant do it well. 我们来帮他吧，否那么他做不好这件事。否认句中否认两个或两个以上并列成分时，用or连接而不用and，用or时，后面不能再用not。例如：3but意为“但是，表示前后两成分之间的转折关系。例如：I go to see him, but he isnt in. 我去看他，但他不在家。10. 不完全爆破当爆破音p b t d k g的任何两个相邻时，那么前面的爆破音只须摆好舌位，并在口腔中形成阻碍，不发出音来，而发后面的一个爆破音，这就叫不完全爆破。它通常用“ 来表示。例如：I dont think so!a good teacher.a big ball.
