名词性从句复习 名词性从句是历年高考的重点和难点也是热点。名词性从句相当于名词,可用作主语、表语、 宾语和同位语。因此,名词性从句分为主语从句、表语从句、宾语从句和同位语从句。引导名词性 从句的连接词有:连接代词:who,whose,whom,what,wh ich,有词义,在从句中担任成分,如主 语、表语、宾语、或定语等;连接副词:when,where.whv,how,有词义,在从 句中担任成分.作 状语;连接词:if(whether) ,asif 虽有词义,但在从句中不担任成分:连接词 that 无词义 一.课前导学 1.名词性从句定义:在主句中起 2. 名词性从句类型: 3.名词性从句的连接词: 1)从属连词: 2)连接代词: 中作主语宾语表语定语。 3)连接副词: 二.课中导教 (一)宾语从句 在复合句中作主句的宾语 . 引导词有连词 that (that 常可省略 ),whether,if; whose,what ,which;副词 when ,where, how, why 等.如: We believe (that) he is honest. I told him (that) I would come back soon. He said (that)he would go there the next day and that his family wouldn’t go there. 宾语从句的注意点: 1).宾语从句一律用陈述句的语序. 2).引导宾语从句的连词 that 也无实际意义,多数情况下可以省略. 3).whether 和 if 都可以引导宾语从句 但: (1).当 whether 后紧跟 or not 时,不用 if. 例: I don’t know whe ther I will stay or not. (2).介词后面的宾语从句不能用 if. 代词有 who, 和 等,在从句中作状语。 和 等,在从句中不充当任何成分。 和 等,在从句 作用的从句。 1 例: I worry about whether I hurt her feeling. 4).that 在宾语从句中 的省略与保留 (1).在主+谓+it(形式宾语)+宾补+that 从句(真正宾语) 的句型中不省略. 例: We must make it clear that we mean what we say. (2).由连词 and 连接的两个由 that 引导的宾语从句中,第二和以后 that 不省略. 例: He told me that he would come and that he would come on time. (二)主语从句 定义:用作主语的从句叫主语从句,它是名词性从句之一。引导主语从句的连接词有:连词 that, whether;连接代词 who, what 和 which;连接副词 when, where, how 和 why。 1)由 whether 及其他连词引导的主语从句放在句首,句后都可。 Whether it will please them is not easy to say. = It is not easy to say whether it will please them. 这是否能让他们高兴很难说 2) 由连词 that 引导的主语从句: That they are badly in need of help is quite clear. 他们急需帮助,这是十分明显的。 注意 A: 但不能省略。 注意 B: 但是这类句子在大多数情况下会放到整个句子的后部去,而用代词 it 作形式主语。 = It is quite clear that they are badly in need of help. 3)连接代词 who ,what ,which, whatever, whichever, whoever What seems easy to some people seems difficult to others. 对于有些人觉得容易的东西对另一些人来说就难了 Whatever was said here must be kept secret. 这里说的话都应当保密。 Whoever makes mistakes must correct them. 凡犯了错误的人都必须改正。 Whatever 和 no matter what 有区别吗? Her cellphone helps her do whatever she wants to do. 她的手机帮她做她想做的事情 4)连接副词 when,where, how, why 等引起的主语从句: 2 that 引导主语从句只起引导作用,本身无实际意义,在主语从句中不充当任何成分, Why he did it remains a mystery. 为什么他要这样做仍然是个谜 (三)表语从句 1.表语从句的引导词: 基本上与主语从句的引导词相同.连词除了 that, whether(不用 if)外,还可以用 because.在连 系动词 seem,look 之后还可用 as though (as if ). 例: (1).That is how mice ruin many stores of grain every year. (2).The question was when the b utcher was likely to come back from the town. (3).The fact remains that a change in land ownership is needed in India. (4).That is what he told us. (5).It seems as if it is going to rain. The problem
