2023年初中英语,牛津译林9年级上册第五单元语法(原因状语从句讲解+练习)下面是我为大家整理的初中英语,牛津译林9年级上册第五单元语法(原因状语从句讲解+练习),供大家参考。

because9AUnit5语法专项：-----because,since,as引导的原因状语从句

原因状语从句通常由

because,since,as引导。

Hedidn’tcometoschoolhewasill.

itisraining,weshallnot(不得；不应该)gothezoo.youcan’tanswerthequestion,I’llasksomeoneelse.1.

because表示直接原因，语气最强。Because引导的原因状语从句多放在主句之后。(1)回答由

why提出的问题，只能用because而不能用

since，as。

------Whyaren’tgoingthere?------------BecauseIdon’twantto.(2)

because不能与并列连词

so同时在句中使用。[任务型阅读-两者互换]Shewaslateforschoolbecauseshemissedthebus.=Shemissedthebus,shewaslateforschool.(3)

because和

becauseof也有明显的区别。because后面要跟从句，而becauseof后面要跟

Heislateforschool

itrainsheavily.

Heislateforschooltheheavyrain.2.

As和

since，因为语气较弱，一般用来表示明显的原因，常翻译成既然。由

as和

since

引导的原因状语从居多放在句首。

Ashehasnocar,hecan’tgetthereeasily.itisSundaytomorrow,wecanstayuplatetonight.

导的分句并不说明前句行为发生的直接原因，只是对前面的内容加以说明、解释或推断。

Theremustbenooneinthehouseforthedoorisclosed.（推断）

巩固练习：

一、填入恰当的原因连词

1.

Ididn’tgotoschoolyesterdayIwasill.2.

everybodyishere,let’sbeginourmeeting.3.

youareinpoorhealth,youshouldnotstayuplate.4.

Iaskedhertostaytotea,Ihadsomethingtotellher.5.

allthepassengersarehere,whydon’twestartatonce?6.

Billwon’tmakeanyprogresshedoesn’tstudyharderthanbefore.AsSinceSince名词短语。

注意：

since

conj./prep

意为

自从...起，引导的时间状语时，主句现完。

as的其他意思：

conj.当..时，随着；因为；正如prep.作为拓展：for作为并列连词，也有因为之意，它用于引导原因状语从句时不位于句首，引
