as引导什么从句时可以省略主语
as引导什么从句时可以省略主语
as解释:conj. 因为;随着;虽然;依照;当…时;prep. 如同;当作;以…的身份
adv. 同样地;和…一样的
当它做连词时,可以引导时间状语从句、方式状语从句、让步状语从句、比较状语从句、原因状语从句。
I wish we could migrate from here every winter, as the birds do! (比较状语从句,主语不省略)
但愿我们能像鸟儿一样,每年冬季从这里定期迁徙!
They couldn't move on as their sledges broke down.(原因状语从句)
他们不能继续前进,因为他们的雪橇坏了
As time went on, many of these first settlers settled down and began to farm and domesticate animals. (时间状语从句,主语不能省略)
随着时间的推移,这些第一批移民的大多数定居下来,开始农耕和驯养动物。
当as引导方式状语从句时,而且主句主语和从句主语是同一人时(表示“正如,就像”),可以省略主语。如
Do as I say, not as told=Do as I say, not as you are told
照我说的去做,别照我做的去做。
Everything goes as expected=everything goes as it is expected
一切像期望的一样进展
当as 引导让步状语从句时,发生倒装,提前的是可数名词单数时,前面的冠词a/an需要省略。如:
Child as he is, he knows a lot of the history of China. (child前面省略了冠词a)
虽然他只是个孩子,他懂得许多中国历史方面的知识。
as都能引导什么从句
-
定语从句。而且只有as引导的定语从句可以 放在句首。
2.时间状语从句。‘当···时候’
3.方式状语从句。‘按照,如同’
4.原因状语从句。‘由于,鉴于’
5.让步状语从句。‘虽然,尽管’,而且引导让步状语从句是句子要倒装。
倒装句中as和although当尽管讲时的用法
as引导的让步状语从句倒装有四种类型(强调让步内容,as可以用though代替)。现在我来给你讲
第一种:adj+as+主语+be
第二种:名词(特别注意是不带冠词的)+as+主语+be
第三种:adv+as+主语+动词
第四种:动词原形+as+主语+动词或助动词
as, though ,although这三个词的用法各有区别.具体来说,as引导的让步状语从句必须倒装;though引导的让步状语从句可以倒装也可以不倒装;而although引导的让步状语从句不能倒装.
e.g. Hard as he tried, he still failed. (他虽然努力了,但仍然失败了.)
Though he tried hard, he still failed.
Hard though he tried, he still failed.
Although he tried hard, he still failed.
who引导定语从句时,在从句中做主语时可以省略吗
有时可以,有时不可以.比如下面这个句子
Jenny is one of those rare people who believes ancient myths.
句中who的后面是名词或不是主语的时候,就不可省略.这里既当主语,又当引导词.如果who的后面有主语,例(I,she...)who就可以省略
when 引导的状语从句可以省略直接省略主语吗
如果从句的逻辑主语跟主句的主语是一致的话,是可以省略的。
例1:
When I was walking in the street yesterday, I came across a friend whom I hadn't seen since graduation.
可以写成:When walking in the street yesterday, I came across a friend whom I hadn't seen since graduation.
例2:When the thief was questioned by the police, the thief felt nervous.
可以写成:When questioned by the police, the thief felt nervous.
如果从句逻辑主语跟主句主语不一致,则从句主语不能省略。
例如:When my father came back from work last night, I was doing my homework.
这里从句主语是my father ,主句主语是I,逻辑主语不一致,所以从句主语不能省略。
that引导定语从句可以省略吗
只有当引导词that做定语从句的宾语成分时可以省略,其他情况不能省略。
The man [(that) I saw in the street yesterday] is my teacher.
The man [that said hello to me yesterday] is my teacher.
The village [(that) I often visit] is my hometown.
The village [that bees a modern city] is my hometown.
注:带()的that可以省略,[ ]括着的是定语从句。
that引导表语从句可以省略吗
可以。如:My idea is we'd better go with them.我的意思是我们最好和他们一块去
由that引导的表语从句如:
The trouble is that he misunderstood me.麻烦的是他误解了我 that是不可以省的
有时,引导表语从句的连词that可以省略
The truth is (that) I didn’t finish my term essay. 事实是我没有写完学期论文。
表语从句中应注意:
1. 连接词that一般不能省略,但当主句中含动词do的某种形式时,that可以省略。如:
What I want to do is (that) I can go up to him and thank him. 我想做的事是走到身边去感谢他。
2. 当句子的主语是:advice, demand, decision, desire, idea, insistence, instruction, order, plan, proposal, remendation, request, requirement, suggestion, wish等名词时,表语从句须用虚拟语气,即:should +do。如:
My advice is that you should go to apologize to him. 我的建议是你应该去向他道歉。
that 引导从句 什么时候可以省略掉that
宾语从句中第一个可以(如果存在一个以上的并列宾语从句的话,第2个从句的that不能省略) 如 I think (that) you are *** art.
定于从句中关系代词that在从句中担任宾语成分角色 如 That's just the thing (that)I want.
欢迎指正。
定语从句和状语从句的引导词何时可省略
定语从句的引导词在从句中做宾语时可省略,但状语从句的不能。
非限制性定语从句 引导词啥时可以省略?啥时不可以省略?
非限定性定语从句的引导词什么时候都不能省略啊,是逗号后面的内容,因此是一个分句,既然是句子就必须要保证主谓宾的完整性,少了引导词很大程度上就说明少了从句的主语,少了主语的句子基本上不成立。如果你说在句中的定语从句,如果先行词所指代的是主句的宾语,可以省略。
