名词性从句连接词对比使用课件

名词性从句连接词的使用(一)that

和what的选用：that和what都可引导所有的名词从句。但是，what除起连接作用外，还在名词性从句中充当成分，可做从句的主语、宾语、或表语。而that在名词性从句中不充当任何成分，只起连接作用。that

主要根据名词性从句中的具体意义,正确的选择who、which、when、where、why、how等连接词，这些连接词既具有疑问含义，又起连接作用，同时在从句中充当各种成分。我们何时举行运动会还没有决定。___________________I

whether,what,when,where等来引导同位语从句.____________ _

_whether

he

在同位语从句中不做任何成分,只起连接作用,无具体含义,且不可省略.We

expressed

the

hope

that

they

hadexpressed.We

expressed

the

hope

that

theywouldcome

China

been

announcedthat

more

middle

school

graduates

beadmitted

university.The

information

that

he

revealed

themeeting

is

great

value.（七） 名词demand,

suggestion,proposal,

advice等词后的同位语从句的语气要用虚拟语气,结构为

should

+

do,should

可省略He

gave

me

a

suggestion

that

I

(

should)

be

calm

now.(八） 宾语从句的时态呼应1.如果主句时态是现在时或将来时,从句谓语可根据句意需要而选用任一种时态.a.他相信他的梦想总有一天会实现的.Hebelieves_________________________

.b.请告诉我你昨天这个时候在干什么.Please
