三、重點(diǎn)句型
1. Take clothing off the burned area unless it is stuck to the burn.
unless 作從屬連詞,引導(dǎo)條件狀語(yǔ)從句,作“除非…..否則”講,相當(dāng)于if…not .
注意①在unless引導(dǎo)的從句里,謂語(yǔ)用一般現(xiàn)在時(shí),不用一般將來(lái)時(shí)。
②在引導(dǎo)的從句里,當(dāng)主語(yǔ)與從句主語(yǔ)是同一人或物,且有系動(dòng)詞時(shí),從句主語(yǔ)與系動(dòng)詞可省略。
E.g. I will not attend the meeting unless (I am) invited.
I won’t call you, ________ something unexpected happens.
A. unless B. whether C. because D. while
Key: A
2. John was studying in his room when he heard screaming.
此句型中when作并列連詞相當(dāng)于and then意為”正當(dāng)……時(shí)突然”,常用于以下句型:
知識(shí)拓展
be doing …when… 正在做……突然
be about to do …when… 即將做……突然
be on the point to do…when…正要去做…..突然
has/have/had done…when… 剛剛……這時(shí) (突然)
3. There is no doubt that John's quick thinking and the first aid skills that he learned at school saved Ms Slade's life.
doubt 名詞,意思是“懷疑”、“疑惑”、“疑問(wèn)”。如:
I have no doubt at all who did it.
知識(shí)拓展:
There is no doubt that…/about sth. 毫無(wú)疑問(wèn)……(肯定句)主語(yǔ)+doubt whether/ is…(否定句)主語(yǔ)+not doubt that 從句
I don’t doubt that his words are true.
There is some doubt whether John will come.
4. It was John’s quick action and knowledge of the first aid that saved her life.
本句為強(qiáng)調(diào)句型結(jié)構(gòu),符合It is/was…that... 結(jié)構(gòu)。
強(qiáng)調(diào)句型It is/was…that/who 的用法歸納如下:
強(qiáng)調(diào)句型可以強(qiáng)調(diào)除謂語(yǔ)動(dòng)詞以外的任何句子成份。一般來(lái)說(shuō),如果被強(qiáng)調(diào)部分是人時(shí),用連詞that或who;如果被強(qiáng)調(diào)部分是物,只能用連詞that. 強(qiáng)調(diào)句型應(yīng)避免使用when, where, which 等連詞。
含一般疑問(wèn)句和特殊疑問(wèn)句的強(qiáng)調(diào)句句型:
① 含一般疑問(wèn)句的強(qiáng)調(diào)句型,其結(jié)構(gòu)為:Is it+被強(qiáng)調(diào)部分+that/who+句子的其余部分?
② 特殊疑問(wèn)句的強(qiáng)調(diào)句型結(jié)構(gòu)形式為:特殊疑問(wèn)詞+is/was it that/who+句子的其余部分?
