Someone wants to use the phone . . 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：Its 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 didnt attend the meeting . I didnt know it . That is because I didnt attend the meeting . They are just what Im 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详细内容。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 . 留意同位语从句同定语从句的区分： 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 假如在从句中充当宾语，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 的干脆宾语，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 dont know when hell be back . I will never forget the day when I joined the army . ( 定语从句 ) very 误用例析 1 . 误 Im very afraid hes out . 正 Im very much afraid hes 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 Im very tired that I cant walk a bit farther . 正 Im so tired that I cant walk a bit farther . 析 very 不能替代 sothat 和 tooto 中的 so 和 too 修饰其形容词和副词。sothat 与 tooto 属于固定句型结构。 4 . 误 It was very impossible for her to catch the 9 oclock train . 正 It was quite impossible for her to catch the 9 oclock train . 析 very 不能修饰 impossible , mistaken , different , right 和 wrong 等不行分等级的形容词。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“特别或 + 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 . Will you wind the wool into a ball? 3 . strong 用作形容词，其名词形式为 strength , 动词形式为 strengthen。例如： Which do you think is stronger , a lion or a tiger? He has a very strong will . They took strong measures at last . The light is too strong for this room . This coffee is too strong for me . He got his strength back slowly after his illness . She doesnt have enough strength to walk upstairs . We want to strengthen our ties with them . 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： Dont interrupt ( me ) while I am working . Im sorry to interrupt you , but theres someone to see you . A flash interrupted the program . 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： The project failed due to lack of money . Lack of heat made us cold . She lacked the experience to get the job . They are so rich that they lack for nothing . 6 . need 既可用作实义动词，也可用作情态动词，意为“须要”。 用作实义词时，其后通常跟名词，带 to 的不定式或动词 - ing 形式作宾语。例如： I need your help . Here are some exercises that need to be done after class . Your telephone needs repairing ( = to be repaired ) . 用作情态动词，通常用在否定句或疑问句中。例如： “Need you go now?”“You , I must . ” You neednt come to the meeting this afternoon if you have something important to do . 7 . announce 用作动词，意为“发表，宣布，告知”，其名词形式为 announcement。 The government announced its new economic policies .
