为了帮助大家强化英语知识点的记忆,下面读文网小编为大家带来初中英语从句相关知识点讲解,供大家参考学习。
原因状语从句应注意的问题
1、because , since , as , for,辨析
1)because语势最强,用来说明人所不知的原因,回答why提出的问题。当原因是显而易见的或已为人们所知,就用as或 since。
I didn’t go, because I was afraid.
Since /As the weather is so bad, we have to delay our journey.
2)由because引导的从句如果放在句末,且前面有逗 号,则可以用for来代替。但如果不是说明直接原因,而是多种情况加以推断,就只能用for。例:
He is absent today, becaus e / for he is ill. He must be ill, for he is absent today.
3) as和for的区别:通常情况下,as引导的从句在主句前,for引导的从句在主句后。例: As the weather is cold, I stay at home.(同义句) I stay at home, for the weather is cold.
2、because习惯上不与so连用
汉语习惯上说“因为…所以…”,但英语习惯上却不能将 so与because 连用:
正:Because it was raining, we stayed at home. / It was raining, so we stayed at home.
误:Because it was raining, so we stayed at home. 因为下雨,所以我们呆在家里。
3、because 从句与 because of短语的转换
Because引导的原因状语从句有时可与because of 短语转换,because of后加的原因可以为好或坏 ,但最正规的还是because。
He can’t come because he is ill. / He can’t come because of his illness. 他因病不能来。
I said nothing about it because his wife was there. / I said nothing about it because of his wife’s being there. 因为他妻子在那儿,我对此事只字未提。

让步状语从句是状语从句中的一种,其本身也是状语从句。一般翻译为“尽管……”或“即使……”,就是我们日常生活中用的“退一步说…”。那么你知道让步状语从句的用法吗?下面跟着读文网小编学习一下吧。
表示“虽然…但是”,“纵使…”之意
as引导的让步状语从句必须以部分倒装的形式出现,被倒装的部分可以是表语、状语或动词原形,though也可用于这样的结构中,但although不可以这样用。例如:
Object as/though you may, I’ll go.(=Though/Although you may object, I’ll go.)纵使你反对,我也要去。
Hard as/ though he works,he makes little progress. (=Though he works hard,he makes little progress.)尽管他学习很努力,但几乎没取得什么进步。
Child as/though he was,he knew what was the right thing to do.(=Though he was a child,he knew what was the right thing to do.)虽然他是一个孩子,但他知道该做什么。
Fast as you read, you can’t finish the book so soon.纵然你读得快,你也不能这么快读完这本书。
Lover of towns as I am,I realize that I owe a debt to my early country life.尽管我爱城市,但我知道,以往的乡村生活使我受益匪浅。
Small as atome are, they are made up of still smaller units.尽管原子很小,但它们由更小的单位构成。
由这一个复合连词引导的让步状语从句旨在说明正反两方面的可能性都不会影响主句的意向或结果,所以它的语气是比较强烈的,从而也更加坚定了主句的内容。例如:
You'll have to attend the ceremony whether you're free or busy.不管你忙不忙,都要参加这个典礼。
Whether you believe it or not,it's true.无论你是否相信,这都是真的。
Whether or not they win this battle,they won't win the war.不管他们是否能赢得这次战役,他们绝不会赢得这场战争。

英语翻译的备考不能只停留在“看”的层面上,要扎扎实实的“做”翻译,提高动手、动笔的能力,那样才能切实的提高翻译水平,那么如何做呢? 在做的过程中应把握哪几步呢,这一定是众多考生迫切要知道的。建议大家,可以把考研阅读中的长难句拿出来翻译,提高一些动手能力。翻译题型自从作为考查考生综合运用语言能力的题型出现后,很多考生觉得难以动笔,认为这种题型的难度较大。而这种题型在近些年的考研英语试卷中出现以后,考察形式已经趋于稳定。考题要求考生在理解全句、全段或全文的基础上,把语法、词汇的意思和上下文结合起来理解。
在英语中,连接目的状语从句的连接词常常有:that(为了,以便),so that(为了,以便),lest(以防),in case(以防,以免),for fear that(以防)in order that(为了)等等。
(一)一般翻译在主句前面。
一般来说,这种表示“为了”的目的状语从句通常放在主句前面翻译。

为了不惊醒她,他轻轻推开房门,悄悄地溜了出去。
We should start early so that we might get there before noon。
为了正午以前赶到那里,我们很早就动身了。

He emphasized it again and again, lest she should forget。
他反复强调这一点,免得她忘了。

☆理解技巧:
分词(短语)用作让步状语通常可转换成由从属连词though, although, no matter…等引导的让步状语从句,如上面两句也可转换成:Although he lived miles away, he attended the course.
Thought he was defeated, he remained a popular boxer.

He came in, followed by his wife. 他走了进来,后面跟着他的妻子。(☆过去分词短语也可以作伴随状语)
☆理解技巧:
理解“伴随状语”的关键是要理解“伴随”二字。分词(短语)用作伴随状语时,它表示的动作伴随句子谓语动作同时发生,即句子谓语所表示的动作为主要动作,分词短语所表示的动作伴随性的次要动作。英语中“动词+ing”形式作伴随状语时,它表示的是一个次要的动作,来对谓语表示的动作加以说明或作为陪衬。一般将其置于句后,可用逗号与主句成分分开。例如: Don’t sit there doing nothing. Come and help me with this table.不要坐在那里什么也不做;过来帮我收拾餐桌
