Ⅱ. 交际英语

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：

They hired five more hands for the rice harvest .

They hired a concert hall with accommodations for 300 people .

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：

The river winds through the jungle .

The road winds up the mountain .

3 . strong 用作形容词，其名词形式为 strength , 动词形式为 strengthen。例如：
