#口語粉碎機(jī)#L1 Day 9【打卡序列10】
今天認(rèn)真完成了晨讀和作業(yè)9:
---whether和if的區(qū)別：
一晚碾、引導(dǎo)賓語從句
這時(shí)兩者的含義區(qū)別很小,一般可通用.
但是,當(dāng)whether與or not連成一個(gè)詞組時(shí),whether不可換用if.
若whether和or not不連在一起,在口語中可以用if取代whether,當(dāng)然也可以用whether.
I don't care if/whether your car breaks down or not.我不在乎您的車是否是會(huì)出故障.
此外,還有三種情況值得注意：
(1)在介詞后面只能用whether,不能用if.
I am not interested in whether you'll come or not.
(2)在動(dòng)詞不定式之前,只能用whether,不能用if.
He doesn't know whether to stay or not.
(3)在及物動(dòng)詞discuss后的賓語從句中,只能用whether,不能用if.
We discussed whether we should make a change in our plan.
二聋溜、引導(dǎo)主語從句
只能用whether,不能用if.
It is unknown whether he will come.
Whether the news is true remains a question.
三杉畜、引導(dǎo)表語從句
只能用whether,不能用if
The question is whether they can take our advice.
四采盒、引導(dǎo)同位語從句常用whether
The question whether he'll come is unknown.
五澄干、if可以用來引導(dǎo)一個(gè)否定的賓語從句,whether則不能用來引導(dǎo)否定的賓語從句,因?yàn)樗硎菊磧煞矫娴倪x意義比較強(qiáng).
Tell me if it is not going to rain,please.
六熊尉、if除引導(dǎo)賓語從句外,還可以引導(dǎo)條件狀語從句,作“是否”解.在容易引起混淆產(chǎn)生歧義的情況下,就不可用if,而須用whether.
Please let me know if you intend to come.這個(gè)句子有兩種解釋：A：“請讓我們知道你是否想來.” B：“如果你打算來,請讓我們知道.”在書面語中,如果我們想表達(dá)的第一種含義,就得用whether來改寫第一句.
Please let me know whether you intend to come.
通俗來講,whether在大多數(shù)情況下都可以用,而if則不然,有wether和if時(shí)一般選wether不會(huì)有錯(cuò),但是如果所需的意思是"如果",自然只能選if了.

5.We can depend on his arriving here on time.
