eyes.=Her eyes are big.2.Who s that boy?这是由 Who 引导的特殊疑问句，询问某人的身份。如：Who s that girl over there?Who s 是Who is 的 缩 写 形 式。名 词 和 代 词 和am,is,are,have,has 的连词都可以使用缩写形式。助动词和情态动词的否定形式也可以缩写。如：Who is=_ Who are=_ _=What s _=Whatre That is=_ can not=_ do not=_ _=doesn t Tom is=_ they are=_ 3.Where is he from?此句是 where 引导的特殊疑问句，旨在询问别人的家乡在哪里或对方的出生地。be from 相当于 come from，因此上句可改为_ 4.That s right.That s right 是对某一观点、判断或回答作评判的用语，或对对方的说法表示赞同，表示“是的，对了，你说的对”。有时也可以用Youre right 或 Right,OK 来代替。如：Are you in Class One?That s right.是的/没错。5.I m thirteen years old.=_。6.Please give this letter to Maria.She is in Class Four,Grade Seven.（1）give 动词，“给”。give sth.to sb.“把某物给某人”相当于 _。(2)Class Four,Grade Seven 英语中一般先说_的地方，后说_的地方。7.Sorry,I don t know her.I m sorry 是英语中最常用的交际礼貌用语之一，意为“对不起”，口语中也可直接用Sorry。8.What does she look like?这是用来询问人的外貌的,可根据人的外貌特征直接进行回答。如：What does he look like?他有一张圆脸和一双大眼睛。_ look like“看起来像”，look 为连系动词,意为“看起来”,“看上去”,like 为介词,意为“像”如:我看起来像我妈妈。_ 辨析：look like/be like（1）look like“看起来像”“看上去像”指“外观像”。（2）be like“像一样”，指“品质、性格。”如：_他长什么样子？_?他是一个什么样的人？(三)重点语法have/has 的用法:动词 have 作为 有使用时，表示 某人(物)有用于第一、二人称单数 I、you 和复数主语，其单数第三人称形式为has，用于第三人称单数he、she、it 和单数主语。肯定句：主语have/has宾语。例如：1.我有一本英语书。_2.莉莉有条狗。._ 3.他们有很多的朋友。_ 否定句:在 have、has后直接加 not。主语 have not/has not+宾语。例如：1.我没有一辆红色的车。_ 2.她没有一只新铅笔。_ 3.莉莉和露西没有一个大家庭。_ 在美语中，要借助于助动词变为问句和否定句，但has 要变为 have。在作回答时也要用do或 does的形式。否定句中，用主语 dont/doesnt+have+宾语。例如：1.我没有一本英语书。_ 2.他没有一辆新的自行车。_ 一般疑问句中，用Do/Does+主语 have+宾语。例如：1.你有一本英语书吗？_2.她有朋友吗？_ 特殊疑问句中，用特殊疑问词do/does+主语+have+其它。例如：1.他们有什么？_2.露西有多少好朋友？_ s的所有格形式：_王海的妈妈 _Jim 的妹妹物主代词的使用：形容词性物主代词和名词性物主代词形容词性物主代词+名词=名词性物主代词人称代词和物主代词的使用：Whose toy is this?It is my toy.=_ It s your toy._It s his toy._ It s her toy._ _ toy.It s its._ toy.It s ours._toy.It s theirs.Topic 2（一）知识点讲解1.We both have black hair and black eyes.both pron.（与复数名词连用）意为“两个，两个都”。both 放在 be 动词，助动词或情态动词后面，实义动词的前面。如_我们都来自重庆。_ 他俩都在伦敦市工作。2.But you look the same.We dont have the same looks,but we are good friends!以上两句中出现了look the same 与 the same looks 两个短语。look the same 中的 look 是动词，意思是“看起来.”，而 the same looks 中的 look 为名词，常用复数，意思是外表，外貌，样子”。因此 look the same 意为“看起来很像”，而 the same looks 意为“相似的外貌”【链接】look at 看.；look like 看起来像。如：_.请看黑板。_.他看起来像他的爸爸。look the same 的反义词组是：_ 3.What color is it?What color 是用来询问颜色时常用的特殊疑问句，该句型的结构是“What color+一般疑问句+其他？”回答语为“Its 或 Theyre+颜色”。What 是疑问代词，可放在名词前修饰说明名词。句中的主语是it，动词用单数is。主语是复数，则动词用are。如：_?他们的皮肤什么颜色？_你的头发是什么颜色？_你喜欢什么颜色？注意：不论句子的主语是单数还是复数，color 只能用单数形式。4.The girl in yellow is Maria.in 在这里是个介词，表示“穿着”、“戴着”的意思，指“穿”的状态，可用于穿鞋、戴帽、穿衣服等。如：_那个穿白色衬衣的男孩是我的哥哥。【辨析】put on,wear 与 in（1）put on 表示“穿上”、“戴上”的意思，其反义词是take off,用法广泛，指“穿”的动作，可用于穿鞋、戴帽、穿衣服等。如：_ 我穿上外套然后去上学。（2）wear“穿着”，表示穿的状态，可以用进行时，宾语除衣服、鞋帽外，还可以是首饰、眼镜、发型等。如：_ 她今天穿着一条新裙子。（3）in“穿着、戴着、留着”，强调状态，宾语既可以是衣服、帽子，还可以是颜色，表示穿什么颜色的衣服。如：_.格林先生穿着一件蓝色的外套。文档编码:CD6R4L10F9L2 HG9G5H2N8B8
