第一课时Section A (1a1c)Unit 2This is my sister.This is my sister.这是我的姐姐。This is.是我们把一个人介绍给另一个人时的常用句型。当被介绍人处于近距离时，单数用this is，复数用these are；处于远距离时，单数用that is，复数用those are。如：This is my friend.这是我的朋友。Are these your brothers？这些是你的兄弟吗？That is my sister.那是我的姐姐。Those are my parents.那是我的父母。Those are my parents.那是我的父母。parents意为“父母亲”，等于father and mother。【拓展】parent父亲或母亲，等于father or (或者) mother。【注意】在英语中，名词分为可数名词和不可数名词。可数名词有单数和复数之分，表示单一数量的人或物用单数形式，表示两个或两个以上的人或物要用复数形式。不可数名词没有单数和复数之分。如：water (水)rice (米饭) hair (头发)Whos she？她是谁？who意为“谁”，是疑问代词的主格形式，常在句中作主语。其宾格形式是whom。【注意】其回答形式应为She is. 一、根据句意及汉语提示完成下列单词。1This is her _(家庭)2_ (这些) are not his friends.3His _ (父母) are Mr. Green and Mrs. Green.4My _(爷爷) is in Beijing.5Her three _(哥哥) are in the No. 1 Middle School.familyTheseparentsgrandfatherbrothers二、单项选择。( )6._ is an English map.AThatsBThatCThese( )7.My father and mother _ in China.(易错题)Ais Bam Care( )8.These are Lucy and Lily.They are my _.Asister Bfriends CbrothersBCB( )9.Your _ are your grandfather and grandmother.Agrandparents Bparents Cparent( )10._ is she?She is my sister.(易错题)AWhat BWho CHow( )11.This is _ brother._ name is Liu Tao.Amy；He Bher；Hes Cmy；HisABC( )_ ( )_ ( )_ ( )_ BisCmyBareDparents四、按要求完成下列句子。16This is a ruler.(改为复数句)_ are _17He is my_good_friend(对画线部分提问)_ _ he?18那是我的外祖父母。(翻译句子)_ are my _19这是他的两个弟弟。(翻译句子)(易错题)_ are his two _TheserulersWho isThosegrandparentsThesebrothers
