Unit2+Topic1++Section+A讲义 仁爱版七年级英语上册.docx
Section A重点讲解【1】I have a small nose. 我有一个小鼻子。 have 是实义动词，不同的语境可以根据汉语习惯翻译成不同的意思，这里可以译成“有”。一个意思完整，能够独立作谓语的动词叫做“实义动词”。实义动词与助动词是相对应的，助动词只起到帮助的作用，不能单独作谓语。【2】But he has a big nose. 但是他有一个大鼻子。a. but 表示转折,在此处用来对比“small”与“big”。b.“has”是 have 的第三人称单数形式。 当主语是第三人称单数时, have 要换成 has。【3】英语中的人称有三种，第一人称，第二人称和第三人称。每种人称都分为单数和复数两种形式，第一人称单数为I(我)，复数为 we(我们)；第二人称单数为you(你)，复数为 your(你们)；除此之外其他的全部为第三人称，一个即为第三人称单数，一个以上为复数。有些同学认为第三人称单数就是“他她它”，其实不然，除了第一二人称以外的单数都是第三人称单数，比如:Tom, Maria, my mother, your teacher, a desk,our school 等等都属于第三人称单数。【4】Do you have big eyes? 你长着大眼睛吗? 当 have 在肯定句中是实义动词时，要改为否定句和疑问句就需要添加助动词了，如果原句动词是原形，那么我们就选用 do 来作助动词,例如:I have big eyes. 我长着大眼睛，这里 have 是原形，那么变否定句、疑问句时就要添加助动词 do。 I dont have big eyes. Do you have big eyes? 如果原句动词是单三,那我们就要选用do 的单三形式 does 了。He has big eyes. 他长着大眼睛。现在动词用了 has，那就要选择 do的单三形式“does”来变否定句或疑问句 He doesn't have big eyes.另外注意在否定句、疑问句中 does一出现，句中的实义动词要回复原形, Does he have big eyes?【5】We have small eyes. 我们长着小眼睛。使用名词时要注意可数名词的单复数，如果是单数要在前面加上冠词a或者 an,例如:I have a big nose. 如果是复数一定要在词尾加 s 或es,例如:It has big ears.【6】She has long hair. 她长着长头发。hair在这里是不可数名词，不可数名词前不用冠词 a或 an，但有时候表示具体几根头发，hair 又可以作可数名词。I have a gray hair. 我长了一根白头发。【7】He has a wide mouth. 他长着一张大嘴巴。 表示嘴巴大用“wide”而不用“big”。a big mouth 来形容说话冒失、不能严守秘密、多嘴多舌的人，所以要慎重使用。基础巩固.根据句意及首字母提示拼写单词，完成句子。1.
