Teacher: What about this dictionary? Anna: It's Helen's.老师：这本词典(是谁的)呢? 安娜：是海伦的。1) What about...? 用于非正式场合中对所谈话题进行反问，或向对方征求意见，表示"...怎么样呢?" / "...又如何呢?" 也可以说 “How about...?” 例：I like English. How about you?我喜欢英语。你呢?I`m busy this afternoon. What about this evening?今天下午我比较忙。今晚怎样?2)此处的Helen's表示"海伦的"。(`s)是"名词所有格"，用于人名或者代人的名词的后边，表示"...的"；需要注意的是当名词末尾是s时，只需要加(`)。例：my brother's name我兄弟的名字Jack's father and John's uncle 杰克的爸爸和约翰的舅舅3. Teacher: Thank you for your help, Ana. Anna: You`re welcome.老师：多谢你的帮助，安娜。 安娜：不客气。Thank you for...和Thanks for...都是表达感谢的方式，在for的后边加上感谢的原因；需要注意当thank后用人称代词宾格形式，thank后有s时不能再加人。例：Thanks for your books.(= Thank you for your books.)多谢你的(那儿本)书。4. How do you spell it? 它(指某单词)如何拼写呢?/(你如何拼写它?)英语中常用代词代替已知的名词，而不重复该词。本句中代词表示需要拼写的单词。用于询问或要求对方拼写单词的表达方式还有：Can you spell it, please?请你把它拼写出来好吗?(你能拼写它吗?)Spell it, please.请把它拼写出来。Do you know how to spell it?你知道它如何拼写吗?5. Lost and Found 失物招领处在西方国家，学生一旦不小心在学校里丢失了东西，就会写一个Lost便条，上面写出所丢物品以及联系方式。同样，当人们拾到了物品，会以相同的方式在纸上写一个Found便条。也有些学校会专门设立一个失物招领处，例如：Lost and Found (box, office, room, desk...)，便于大家找回丢失的物品。6. Ask the teacher for it.去老师那里拿。/到老师那儿去领。“Ask...for...”表示"向某人索取某物；向某人要某物"。例：You can ask him for the dictionary.你可以找他要那本词典。Don't ask me for it. Go and ask your father (for it).不要向我要(它)，去向你爸爸要吧。7. E-mail me at mary@qq.com. (请)给我发电子邮件到 mary@qq.com。Call me at 685-6034.(请)拨打电话 685-6034 找我。1)at放在电子邮箱的地址或电话号码等前面，表示"按照...；根据..."。例：Please meet me at No.202, Xingging Road.请在兴庆路202号与我见面。2) mary@qq.com是一个电子邮箱地址，其中符号@是at的缩写，读作at, com前的实心点读作dot8. I must find it. 我必须找到它。/我一定要找着它。该句中must的含义是"必须"、"一定"，属于情态动词。例：I must go now. 现在我必须走了。9. a set of keys 一串钥匙；一套钥匙a set of表示"一套..."、"一副..."等。例：a set of books 一套书籍；一套图书a set of music CDs 一套音乐光碟语法精讲代词之物主代词物主代词是表示所有关系的代词，分为形容词性物主代词和名词性物主代词两种。形容词性物主代词相当于形容词, 可以理解成“谁的”，但一般不会单独运用，可以通过平时表达“谁的东西”中分析出，当物体或事件前要加形容词形物主代词，简化理解为---“物前用谁的”。例: my name 我的名字your birthday 你的生日their parents 他们的父母 名词性物主代词相当于名词，可以理解成“谁的东西”，表示属于谁的物体，可以通过平时表达“谁的东西”中分析出，这个表达中即有人的表达，也有物的表达，因此当想要两者都要的时候，就要用名词性物主代词。简化理解为 “填物给人用谁的东西”。例: This book is mine. 这本书是我的(书)Those are not her pencils. Hers are here. 那些不是她的铅笔，她的(铅笔)在这里。Our teacher is from China, theirs are from Canada. 我们的老师来自中国，他们的(老师)来自加拿大。指示代词 表示"这个”、"那个”、"这些”、"那些”等指示概念的代词叫指示代词。1)this这个(单数)/these这些(复数)，这两个词用于指时间或空间上较近的事物例：Is this your pencil?These are his brothers.These yellow socks are good.2)that那个(单数)/those(复数)，这两个词用于指时间或空间上较远的事物例：That dictionary is Helen's.How much is that white bag?Are those your parents? 基础主谓一致英语中因为主语人称或者数的不同，后面谓语(do)或者(be)的形式会产生不同，这也是英语形在前意在后的一种典型表现。规则如下：(一般现在时条件下) 系词be的变化规则单数人称：第一人称I---am第二人称you---are第三人称he/she/it---is可数名词单数---------------------------------is复数人称(谁们)和复数名词---------------are不可数名词------------------------------------is总结：谓语除单数和不可数加s/es外，其余都用复数。系词： 我用am你用are，is跟着各种ta 东西单或不可用is，复数全都要用are句型---主系表英语中有一种句型称作主系表句型。其中主语大部分情况下是由名词或者代词及其相应词组充当，表示句子主要角色。表语大部分情况下由名词、代词、数词或者形容词及其相应词组充当，起到表达表示主语的状态或性质的作用。系词一般是由be以及变形am/is/are充当，会随人称和数产生相应的变化，系词起到连接作用，把主语和表语连接起来。例：My name is Gina.His phone number is 123456789.This is my sister.These are his pencils.主系表的各种变化01) 陈述句中肯定变否定----方法，系词后+not肯定： This is my pencil. 主语 系词 表语否定： This is not my pencil.主语 系词 表语02) 肯定句变一般疑问句及其回答----主系换位/系词提前，大写变号。------(我变你，我的变你的)肯定： This is my pencil . 主语 系词 表语一般疑问：Is this your pencil ？ 系词 主语 表语回答： Yes, this/it is. / No, this/it is not(=isn't).
