【 指点迷津 】

　　单元重点词汇点拨

　　1 . pair 一对；一双

　　I need a pair of shoes .

　　The children came in pairs .

　　〖 点拨 〗pair可作量词连接可数名词和不可数名词，如：a pair of glasses 一幅眼睛。two pairs of paper两张纸。 a pair of new shoes 一双新鞋。in pairs 成双，成对。

　　2 . size 尺寸；大小

　　What size shoes do you wear ?

　　This book ( house ) is the same size as that .

　　〖 点拨 〗medium - sized 中号 ( 型 ) 的，large - sized 大号 ( 型 ) 的。the same size as …同…一样大。

　　3 . bit 一点儿；小片

　　Have you a little bit of bread ?

　　〖 点拨 〗 a bit 用于形容词前，指“有点，相当”，a bit of 用于名词前，表示一点点

。not a bit 一点也不，而 not a little 相当于 very。

　　4 . suit 一套 ( 衣服 ) ；西服

　　Father bought him a suit of new clothes .

　　His new suit doesn/t fit well .

　　〖 点拨 〗 suit 还可作动词用表示： ( 衣服、颜色等 ) 合身、适合，如：The new dress suits you very well .

　　5 . name 1 ) 命名；名叫；说出……名字

　　I know a girl named Joan .

　　Can you name all the flowers in the garden ?

　　2 ) 名字，姓名，名称

　　Her name is Mary .

　　〖 点拨 〗name sb . sth 给某人起名叫……。Someone named … 名叫……的一个人。

　　6 . for 因为 ( 连词 )

　　I asked her to stay to tea , for I had something to tell her .

　　We must start early for we have a long way to go .

　　〖 点拨 〗for 常引导补充说明的理由原因。不能回答 why 提出的问题。

　　7 . dollar 美元

　　Dollar is a unit of money used in the U . S . A , Canada , and some other countries .

　　〖 点拨 〗dollar 前有数词修饰时，dollar 须加 -s。

　　8 . perhaps 可能；也许

　　Perhaps he will be there , but perhaps he won/t .

　　Perhaps she wasn/t angry with you .

　　〖 点拨 〗perhaps 也许，是“也许如此，也许不如此”的意思。语气很委婉、相当于 maybe。

　　9 . retell 重述；重讲

　　The children are asked to retell the story .

　　〖 点拨 〗retell 是由动词 tell 加前缀 re - 构成，前缀 re - 表示“又、再、重”。如：rewrite 重写。
　　
　　10 . dinner 正餐；宴会
　
　　It/s time for dinner .

　　I/m busy cooking dinner .

　　Shall we give a dinner for her birthday ?

　　〖 点拨 〗表示“吃饭”的动词，英国人一般用 have , 美国人用 eat , dinner 前加冠词表示一顿一顿的饭食，不用冠词时，通常表示吃饭这件事。
　
　　11 . pardon 原谅；宽恕；对不起

　　Pardon me for being late .
　
　　Please pardon me for waking you .

　　I beg your pardon . I don/t know this was your seat .

　　〖 点拨 〗I beg your pardon . = Beg your pardon . = Pardon . 读升调时，意思是“请再说一遍”。读降调时，意思是“请原谅，对不起”。 pardon sb . for ……原谅某人……
　　
　　12 . dirty 脏的

　　My dress is getting dirty .

　　Wash your dirty face ( hands ) .

　　13 . brush 1 ) 刷；擦 ( 动词 ) 2 ) 刷子 ( 名词 )

　　Brush your teeth every morning .

　　〖 点拨 〗a tooth brush 牙刷 / a clothes brush 衣刷 a writing brush 毛笔
　　
　　14 . simple 简单的；简易的；简朴的

　　The book is written in simple English .

　　The old man lived a simple life .

　　〖 点拨 〗live a simple life 过朴素的生活

　　16 . finger 手指

　　We use our fingers to feel and pick up things .

　　〖 点拨 〗大姆指：thumb , the forefinger 食指 , the middle finger 中指, the ring finger 无名指, the little finger 小指 。

　　单元词组思维运用

　　1 . wear out 穿坏；穿旧；用尽， ( 使 ) 精疲力尽

　　2 . a pair of 一对；一双；一副

　　7 . never mind 不要紧；没关系

　　―― Never mind , It isn/t heavy . I can do it myself .
　
　　―― I forgot to bring your book .

　　―― Never mind about that , I/ll get it back tomorrow .

　　8 . in surprise 惊奇地
　　
　　He looked at me in surprise with his mouth open .

　　说明：to one/s surprise使某人感到惊奇的是……如：

　　To my surprise , the little girl can carry such a heavy box . 使我惊奇的是，那个小女孩竟能搬动那么重的箱子。

　　9 . much too 实在太；过于

　　You are much too kind to me .

　　辨析：much too 与 too much 不同。too much 是“太多…”的意思，用在不可数

　　名词前面，可作主语，作表语，作宾语。much修饰形容词和副词。如：

　　It/s much too cold . 天气实在太冷。( much 是程度副词，修饰 too，加强语气 )

　　We/ve had too much rain lately . 最近我们这里的雨下得太多了。 ( much 是修饰 rain 的形容词，又被 too 修饰 )

　　10 . think about 思考；思虑；回想

　　What are you thinking about ?
　　
　　They are thinking about leaving tomorrow .

　　11 . sell out 售完

二、学海导航

【 学法指要 】

　　单元难点疑点思路明晰

　　1 . Can/t they be mended ? 难道它们 ( 鞋子 ) 不能修吗 ?

　　以否定形式提问的疑问句叫否定疑问句。这种疑问句包括一般疑问句和特殊疑问句的结构。句中的 not 可以和有关的 be、have 以及助动词、情态动词结合，构成 - n/t 形式放在主语之前。

　　一般否定疑问句往往表示怀疑、惊讶、责备等意义，实质上它具有强烈的“肯定”意味。如上述的例句，问话者的心中是相信它肯定能修。又如：

　　Can/t you ( really ) ride a bicycle ?

　　Haven/t you forgotten something ? 难道你们没忘记什么吗 ?

　　2 . They were so pleased to see each other that they forgot everything else . 他们彼此见面，格外高兴，把所有的事都忘了。

　　①so…that 意思是“如此……以致。”so 修饰它后面的形容
