    一、教法建议
    【 抛砖引玉 】
    单元双基学习目标
    Ⅰ. 词汇学习
    get together, all the best , have a word with , in other words , excellent , chat , connect … with , hire , wind ( vt . ) , strengthen , frequently , recover , smart , distant , lately , interrupt , remind , lack , due , income , announce , bargain , sew , needle , thread , frequent , free of charge , dial , have … on conversation , handle ( n . ) , directory , telephone ,

    Ⅱ. 交际英语

    1. Hello . Can I speak to … , please? There is no … here .

    2. I\m sorry . I think I dialled the wrong number .

    3. Hello . Is that … ? I called to ask/tell you …

    4. Hold on . I\ll go and get …

    5. Please could I have a word with … ?

    6. I\ll have to ring off now . Someone wants to use the phone .

    Ⅲ. 语法学习

    进一步学习名词性从句的用法。

    作用相当于名词的从句叫名词性从句。名词性从句包括主语从句、表语从句、宾语从句

    和同位语从句。

    1 . 主语从句:复合句中充当主语的从句叫主语从句。如:

    That he is ready to help others is well - known .

    ( that 引导主语从句在从句中没有含义,也不充当成分,但不宜省略。 )

    Whether he will attend the meeting is not decided . ( 不用 if 引导主语从句。 )

    其他的连接词还有 who , what , which , when , where , how , why 等。如:

    Which team will win the match is still unknown .

    What we need is your help .

    How he became a famous musician is known to all .

    主语从句做主语,句子显得不太平衡,因此常将它移到名子后面,前面用引导词 it 来作形式主语。如:

    It\s a pity that she had made such a mistake .

    2 . 表语从句:用作表语的从句叫表语从句。如:

    That is why I didn\t attend the meeting .

    I didn\t know it . That is because I didn\t attend the meeting .

    They are just what I\m looking for .

    其他连词还有 that , whether , as if , who , which , when , where , how , why 等。

    3 . 同位语从句:用作同位语的从句,叫同位语从句。

    它一般跟在抽象名词 ( 如 idea , news , fact , possibility 等的后面,用以说明名词所表示的具体内容。引导同位语的词有连词 that , 连接副词 how , when , where 等。如:

    The idea that computers will recognize human voices surprises many people .

    The possibility that the majority of the labour force will work at home

    is often discussed .

    注意同位语从句同定语从句的区别:

    1 ) 同位语从句的连接词 that 在从句中不充当成份,没有实际含义,而定语从句的连接词 that 在从句中常做主语或宾语。如:

    The news that he told us just now is exciting . ( 定语从句 )

    The news that our team won the game is exciting . ( 同位语从句 )

    2 ) 同位语从句的连接词 that 在从句中不能省略,而定语从句的连接词 that 如果在从句中充当宾语,可以省略。如:

    The news that he told us just now is exciting .

    句中的 that 在从句中做 told 的直接宾语,所以可以省略。

    3 ) 同位语从句常用连接词 that , 连接副词 when , where 等常用于 have no ( some ) idea 后。如:I have no idea when he will be back . ( 同位语从句 ) = I don\t know when he\ll be back .

    I will never forget the day when I joined the army . ( 定语从句 )

    【 指点迷津 】

    very 误用例析

    1 . [ 误 ]I\m very afraid he\s out .

    [ 正 ]I\m very much afraid he\s out .

    [ 析 ]very 不能修饰 afraid , asleep , awake , alone , alive 等表语形容词,这类形容词要用其他副词修饰。如:be wide awake , be fast ( deep , sound ) asleep , be quite alone , be very much alive。

    2 . [ 误 ]The situation seems to be very improved .

    [ 正 ]The situation seems to be very much ( much ) improved .

    [ 析 ]在没有形容词化仍有动词性的现在分词和过去分词之前不能用 very , 应用 very much 或 much。very 只能修饰 amusing , disappointing , exciting , interesting , moving , pleasing , satisfying , devoted , interested , learned , pleased , surprised , tired , worried 等形容词化的分词。

    3 . [ 误 ]I\m very tired that I can\t walk a bit farther .

    [ 正 ]I\m so tired that I can\t walk a bit farther .

    [ 析 ]very 不能替代 so…that 和 too…to 中的 so 和 too 修饰其形容词和副词。so…that 与 too…to 属于固定句型结构。

    4 . [ 误 ]It was very impossible for her to catch the 9 o\clock train .

    [ 正 ]It was quite impossible for her to catch the 9 o\clock train .

    [ 析 ]very 不能修饰 impossible , mistaken , different , right 和 wrong 等不可分等级的形容词。修饰这些词时,常用 quite。

    5 . [ 误 ]The book is very worth reading .

    [ 正 ]The book is well worth reading .

    [ 析 ]worth 是表语形容词,表示“很值得……”时,常用 well 修饰而不用 very。

    6 . [ 误 ]He is very anxious to leave .

    [ 正 ]He is too anxious to leave .

    [ 析 ]句式“主语 + 系动词 + ( only , , but ) too + adj . + to do sth . ”,意为“非常或 + 分……去干某事”,此时不用 very 代替 too。能用于这一句式的形容词有 anxious , eager , ready , pleased , glad 等。

    二、学海导航

    【 学法指要 】

    单元重点词汇点拨

    1 . hire 常用作动词,意为“雇用 ( 某人 ) ( = employ ) ;租借 ( 东西 ) ( = rent ) ”。例如:

    2 . wind 用作动词时,为不规则动词,过去式和过去分词都是 wound , 可以表示“ ( 道路、河流等 ) 弯曲,蜿蜒; ( 把毛线等 ) 卷起,卷成球; ( 把某物 ) 卷在 ( 某物、人等 ) 上,缠绕;上紧 ( 发条 ) ”。例如:

    4 . interrupt 意为“阻碍 ( 某人 ) ,打断 ( 某人 ) 的话;使 ( 工作、谈话等 ) 中断, ( 使 ) 终止”。例如:

    5 . lack 既可用作名词,意为“欠缺,不足”;也可用作动词,意为“缺少……, ( 对 ) ……不充裕”。例如:
