now that引导的句子

But now that you are here,I don’t have to.

但是，既然你在这儿，我就不必了。

(1)句式分析：这是一个主从复合句。主句是I don't have to，now that you are here是连词now that引导的原因状语从句。

(2)now that意为“既然”。

Now that the kids have left home we've got a lot of extra space.

孩子们都离开家了，我们住着就更宽绰了。

Now that you have finished your work, you'd better have a rest.

既然你的工作已经做完了，最好休息一下吧。

[易混辨析]

now that, because, since, as, for

now that	固定短语，意为“既然；由于”，引导原因状语从句，that 可以省略。
because	表示直接的或为人所不知的原因，语气最强。回答用 why 提问的问句。
since	意为“既然”，表示已知或共知的原因，但并非直接原因。可与 now that 互换。
as	意为“由于”，表示显而易见或已为人所知的原因。语气比 because 弱。
for	意为“因为”，并列连词，表示补充说明的理由。引导分句，不能置于句首。

类似 although/though 不能与 but 连用，because 不能与 so 连用，当 since, now that 引导原因状语从句时，主句前不能加 so 等连词。

[译]既然你已经准备好了，我们现在可以走了。

[误]Now that you are ready, so we can go now.

[正]Now that you are ready, we can go now.

状语从句省略的具体用法

Then he folds the bill and slowly unfolds it again，as if looking at something he can't believe is there.

然后，他折起钞票，又慢慢地把它展开，就好像看到了什么他不敢相信的东西。

(1)句式分析：这是一个主从复合句。主句是Then he folds the bill and slowly unfolds it again，后面是as if引导的方式状语从句，something he can't believe is there是省略了连接词that的宾语从句，其中又包含了定语从句he can't believe，修饰先行词something。

(2)此处as if looking at something he can't believe is there是状语从句as if he is looking at something he can't believe is there的省略形式。

状语从句省略的具体用法：

①适用从句：时间、地点、条件、方式和让步状语从句

②省略条件：从句主语与主句主语相同或从句主语为it，且从句的谓语部分含有be动词

③省略后从句的形式：连词＋形容词/副词/分词/不定式/名词

While (they were) building the tunnel，the workers discovered an underground lake.

建隧道时，工人们发现了一个地下湖。

Unless (you are) asked to speak，you should remain silent at the meeting.

开会时，除非让你发言，否则你应当保持沉默。

Even if (I am) invited，I won't go.

即使被邀请，我也不去。

When (she was) very young，she began to learn to play the piano.

她很小就开始学习弹钢琴了。

[巧学妙记]

状语从句省略口诀：

时，条，让，方，地；主语同，谓语be，

二者省去不可惜；从句主语是it，省去it's也可以。

表示否定或半否定意义的词语＋助动词/be动词/情态动词＋主语＋动词原形(不含be动词)＋其他”结构

I remember thinking that never would I hold such a note as this...

记得当时我以为我(手里)永远不会握着这样一张钞票……

(1)句式分析：这是一个主从复合句。包含一个宾语从句that never would I hold such a note as this...，该从句是一个倒装句，正常语序为I would never hold such a note as this ...。

(2)never would I hold such a note as this...是否定或半否定意义的词语位于句首时引起的部分倒装。

当表示否定或半否定意义的词语如nor，neither，not，never，seldom，hardly，rarely，little，by no means，nowhere，in no way，under no circumstances，at no time，not until等位于句首时，句子要用部分倒装结构，即把助动词/be动词/情态动词移至主语之前，构成“表示否定或半否定意义的词语＋助动词/be动词/情态动词＋主语＋动词原形(不含be动词)＋其他”结构。

get＋过去分词

你得等很长时间才能拿到钱。

(1)句式分析：这是一个简单句。to get paid是不定式短语作目的状语。

(2)句中get paid是由“get＋过去分词”构成的短语。
