特指的地点。 eg. The school was built where there had once been a cemetery. 学校建在一座墓园的旧址。 5、wherever, anywhere 和 everywhere 表示“任何地方”。 eg. No matter where you now are in writing, you can improve with practice. 不从句是常用状语从句管你在写作上你处于什么水平，练习都能帮你提高。 6、where引导定语从句时，从句前应有一个表示地点的名词作先行词；而状语从句前则无需先行词。 eg.

去看王夫人，但是我不知道她住在哪里。宾语从句用陈述语序。 3. --- Go and ask Mr. White for help. --- But I don’t know _______. A. where does he live     B. where he lives C. where is he living       D. he lives there 答案： B 解析： 宾语从句用陈述语序 4.-- Can you tell me ______? - -- Yes, he lives in a small town. A. where he lives      B. who is singing C. when he will leave     D. what he said 答案：A 解析： 宾语从句用陈述语序，主句用一般现在时，从句根据实际情况用相应的时态，他住在哪里应用一般现在时态，是现在的一种状态。 5. Have you decided ______ for London? A. when will you leave     B. when you will leave C. when are you going     D. when you are going 答案： B 解析：你还没有决定什么时候去伦敦吗？宾语从句用陈述语序，因为是你打算去伦敦，现在并没有在伦敦，或是已经去从句是一个客观真理，因此从句的时态不受主句过了，所以从句用一般将来时。 6.Excuse me. Could you tell me ______our tickets? A. where do we show     B. where shall we show C. where did we show     D. where we shall show 答案：D 解析：不好意思打扰了，你能告诉我，我们将在哪儿检票呢？宾语从句用陈述语序，主语是第一人称，所以可以用shall+动词原形。 【小知识】宾语从句的语序 一般疑问句变为宾语从句时语序要变为陈述句语序，用whether，if连接。 一般疑问句：Does he study hard？ 他学习认真吗？ 宾语从句：I wonder if（whether）he studies hard. 我不知道他是否认真学习。 一般疑问句：Will they win？他们会赢吗？ 宾语从句：I asked if（whether） they would win. 我问他们是否会赢。

能用if not。 eg. She would be angry if you had not invited her to party.      你要是没邀请她，她肯定生气。 4. 和否定表达连从句用时，只能用unless。 eg. I will go unless nobody invite me.       除非没人邀请我，否则我肯定会去。 好了以上就是小编为大家整理的unless和if not的异同，在条件状语从句中，这两个词是常用引导词，且意思相近所以经常会被用来替换，但如果想让自己的英语表达更加标准，更加地道，那就一定要注它们之间细微的差异。

从句 定语从句（Attributive Clauses）在句中做定语，修饰一个名词或代词，被修饰的名词，词组或代词即先行词。定语从句

好用whether表示“是否”。 三、whether引导主语从句时，既可以直接位于句首，也可以位于句末；if引导主语从句时只能用于it作形式主语的从句中。例如： 1. Whether we need it is a different matter. 2. It is a different matter whether(if)we need it. 四、在宾语从句中，当表示“是否”时，whether与if可以互换，但如果从句中有or not 时只句子中，whether和if本身有意义(都表示“是否”)，在从句中不可省略。它们的区别最主要的就是：whether 可以引导所有的名词性从句能用whether 引导。例如： I don’t know whether he will come or not. 五、whether引导的从句可以充当介词宾语，if则不行。 I worry about whether i hurt her feelings. 六、whether引导的从句可以作名词的同位语，if则不行。 The question whether we need it has not been decided. 七、可能造成歧义时，用whether而不用if。 1. please let me know whether you are coming. 请告诉我你是否要来。（whether引导宾语从句） 2. please let me know if you are coming. 如果你要来，请告诉我。（if引导状语从句）

有些句子，虽没有含条件关系的连词，却也隐含着条件关系，我们称之为含蓄条件状语从句，接下来，小编就为大家讲解一下含蓄条件状语从句的相关语法！   这些句子常用一些词，如but for, without 等引出一个介词结构来表示条件，条件应该是虚拟的，或与事实相反的假设。 例如：but for 若非，要不是 You may consider it useless, but for our customers it's an all-important sign of good service. 您句子，虽没有含条件关系的连词，却也隐含着条件关系，我们称之为含蓄条件状语从句也许会认为这样毫无用处，可是对于我们的客户而言，它却是优质服务的重要体现。 The first series was really bad. But for some reason the public took to it.  第一部系列剧糟透了，可是不知为何，观众开始喜欢上了它。 Spurs could have had several goals but for some brilliant saves from John Hallworth.  要不是约翰·霍尔沃思几次精彩的扑救，热刺队原本可以射进好几个球。   例如：without 如果没有...就不... You can't have one without the other, as the song says.  就像歌里唱的那样，两者密不可分，不能只取其一。 In a strangled voice he said, "This place is going to be unthinkable without you."  他哽咽地说道：“没有你这个地方会变得不可想象。” I tell you, Carrie, before God, I can't live without you.  我告诉你, 嘉莉, 苍天作证, 没有你我就活不下去.   例如：otherwise 否则 We didn't know his telephone number, otherwise we would have telephoned him. 我们不知道他的电话号码，否则我们就会给他打电话。 This is the one blemish on an otherwise resounding success.  如果没有这个小小的失误，这就是一次彻底的胜利。 If he had done otherwise, I should have thought him a rascal.  如果他不这样做, 我就认为他是个恶棍.   看来外国人也是有含蓄的一面的嘛，大家可以学着用哦，喜欢就收藏起来吧~

从句表达人或事物的属性或特征的不同程度。主要运用于形容词和副词的原级、比较级及最高级的句果与主句的谓语动词一致，且为行为动词时，常用do（does，did）代替，以免重复。例如： We have produced even more coal this year than we did that year. 我们今年出产煤要比去年出产得更多。 She drives better than her husband does.  她开车开得比她丈夫好。 2.①“no+比较级+than”（不比…多，不少于）。no是副词，在主句中作状语，修饰形容词或副词的比较级；than是连词，引导从句。例如： Tom is no less diligent than peter.   汤姆用功不比彼得差。（汤姆和彼得同样用功） He feels no better today than he did yesterday.他今天的感觉不比昨天好/他今天

同位语从句有以下五种翻译方法： 　　①可以直接翻译在所修饰词后面。 　　②放在所修饰的名词前面，充当定语。 　　③译成独立句子：先翻译主句，然从句有以下五种翻译方法： 　　①可以直接翻译在所修饰词后面。 　　②放在所修饰的名词前面，充当定语。 　　③译成独立句子：先翻译主句后用“就是……”或者“即……”引导出同位语从句，或者把同位语从句译成独立的句子，由冒号或破折号引出。 　　④用代词指代：先把同位语从句中的内容翻译出来，在后面用“这”或“那”等代词复指它，参加句子主体的构成。 　　⑤译成宾语 ：把同位语从句修饰的名词转译成动词，而把同位语从句译成宾语。 　　【真题例句】 　　What is harder to establish is whether the productivity revolution that businessmen assume they are presiding over is for real. 　　【解析】 　　句子可拆分为：What is harder to establish is //whether the productivity revolution //that businessmen assume //they are presiding over// is for real. 　　主句为What is harder to establish is whether the productivity revolution is for real。主句包含两个从句成分：从句what is harder to establish做主语；whether the productivity revolution is for real作表语；that they are presiding over为定语从句修饰the productivity revolution;此定语从句中businessmen assume为主谓结构的插入语。以what, whatever, whoever, whether, when, where, how, why等词引导的主语从句及表语从句在翻译的时候，一般可以按照英语原文顺序来翻译。 　　【参考译文】难以确定的是，商界人士认为他们所主导的生产力革命是否真的存在。
