宾语从句

that引导的宾语从句

当谓语动词表示肯定的概念，如“希望、相信、知道、说”时，其后面的句子一般用that引导。that没有任何词汇含义，只有语法功能，目的是使读者清楚后面的句子是宾语从句。多数情况下that可以省略。

Ihope(that)itwillsnowthiswinter.

Bettythinks(that)treescanimprovetheairquality.

Iknow(that)heisfriendly.

that不可省略的情况。

句中有两个或两个以上由that引导的宾语从句，只有第一个that可以省略

当it用作形式宾语代替that引导的宾语从句时

当宾语从句是双宾语中的直接宾语时

Kevinsaid(that)thebookwasveryinterestingandthatallthechildrenlikedtoreadit.

Hethinksitimportantthatwetrytodosomehouseworkafterschool.

Jacktoldmethathewouldputsomesignsontheenvelope.

if/whether引导的宾语从句

(1)由whether/if引导的宾语从句，实际上是由一般疑问句演变而来的。常用来表达不确定的概念，可以翻译为“是否”宾语从句用陈述句语序（主语+谓语+其他成分）。

Idon’tknow.../IsthegirlinredJenny

→Idon’tknowwhether/ifthegirlinredisJenny.

我不知道穿红衣服那个女孩是否是Jenny。

(2)if或whether引导宾语从句时，作“是否”讲，一般情况下，两者常可换用。

只用whether

在动词不定式之前只能用whether

在whether…ornot的固定搭配中

在介词后只能用whether

宾语从句放在句首表示强调时

Ican’tdecidewhethertoleave.

Iwanttoknowwhetherit’sgoodnewsornot.

IworryaboutwhetherIhurtherfeelings.

Whetheritistrueornot,Ican’ttell.

宾语从句的时态取决于主句的时态

主句使用现在时，从句可根据语境确定需要的时态；主句使用一般过去时，从句除表示“真理”可使用现在时态外，其余相应地使用过去的某种时态。

Ithink(that)youareright.

HethoughttheTVplaywasveryinteresting.

Myteachertoldmethattheearthgoesaroundthesun.

e.g.Whataninterestingstoryitis!

(2)What+形容词+可数名词复数或不可数名词(+主语+谓语)!

e.g.Whatexcitingnews!

多么有趣的一个故事啊！

多么令人兴奋的消息！

感叹句是用来表示人的喜怒哀乐等情感，通常用what或how来引导。

how引导的感叹句的结构为：

How+adj./adv.(+主语+谓语)！

e.g.Howhardtheyarestudying!

How+adj.+a/an+可数名词单数(+主语+谓语)！

e.g.Howinterestingastoryitis!

How+主语+谓语

e.g.Howtimeflies!

他们学习多么努力！

这是一个多么有趣的故事啊！

光阴似箭！

表感叹时，how与形容词、副词连用；what与名词连用。
