that,if/whether引导的宾语从句&感叹句
一、that,if/whether引导的宾语从句
1. 宾语从句的含义
在复合句中,如果由一个句子充当句子的宾语,这个句子叫作宾语从句。引
导词有that,whether,if,what,which,when,why,how等,本单元主要学习
that和if/whether引导的宾语从句。
2. 宾语从句的引导词
(1)that本身无具体含义,引导宾语从句时,表示确定性,在宾语从句中不
充当任何成分,只起连接从句的作用,可省略。例如:
I think (that) students should learn about traditional culture.我认为学生们应该
了解传统文化。
(2)if或whether意为“是否”,引导宾语从句时,表示疑问性,在宾
语从句中不充当任何成分,只起连接从句的作用,常放在动词 ask,see,
say,know,wonder或find out 等后面。一般情况下,两者常可换用,口语
中多用if。例如:
Nobody knows whether/if it’ll rain tomorrow.没有人知道明天是否下雨。
3. 宾语从句的时态
宾语从句的时态应和主句的时态保持一致。即当主句为一般现在时,从句可
根据自身的时间状语选择时态;当主句为一般过去时时,从句需将自身时态调整
为过去的某种时态。例如:
Tom asked if/whether I had read the book.汤姆问我是否看过这本书。
[交流分享]
从句描述客观真理时,则不受主句时态的影响,只能使用一般现在时。
二、感叹句
语法概述:带有浓厚的感情的句子叫感叹句。感叹句一般用降调。what和
how可用来引导感叹句。
