【 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

　　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……

　　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

　　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 )
