否定的转移是指英语否定句在句中某一部分（常在谓语部分），但在语义上却是否定另一部分的现象。翻译这类句子时不要单纯依赖语法分析，而应从语义上分析，根据上下文理解句意。例：
He doesn’t teach because teaching is easy for him. 他之所以教书，并不是因为他觉得教书轻松。
一、否定形式在表示“看法”的谓语动词上，语义上却是否定后面的宾语从句。
此类动词有：think, believe, suppose, imagine, expect, anticipate, fancy, consider, find (感到), guess,
be supposed to, calculate, figure, reckon。
- I don't believe I've met you before. ("I believe I haven’t met you before.") 我认为我没有见过你。

- He doesn't expect we need worry. 他认为我们不必着急。
- I don’t recon she is old enough to go to school. 我认为她还没到上学的年纪。
注：上述判断性动词出现以下情况时，其否定不发生转移：
（1）用作插入语时：
-Li Lei, I think, won’t be angry with you. 我想李蕾不会生你的气。
-Tom, I suppose, won’t be against it. 我猜想汤姆不会反对。
（2）这些动词跟其他另一个动词一起做并列谓语时：

（8）由于cannot help, ought not， need not， not at all等短语的关系而把I think 隔离：
- I should have thought sometimes you couldn’t help thinking of the past. 我应该想到你会禁不住想起过去。
- I think you ought not to walk at night alone, Mrs. Moore.
- I think you need not be impolite to her，as well as to her son.

二、否定形式在表示“感觉”的谓语动词上，语义上却否定表语部分。

注：含有not … because (of) 的句子，情况较复杂，需根据逻辑、语境和常识进行判断是否需要作否定转移，如需转移的话，往往是由否定谓语转为否定状语。例如：
- I don’t teach because teaching is easy for me. 我教书并不是因为我觉得教书轻松。
- The engine didn’t stop because the fuel was used up. 发动机并不是因为油用完而停车的。
- He didn’t go to class because he was sick. 他没去上课，因为他生病了。 (这句话不需作否定转移)
- The manager didn’t give a speech because he felt painful in his throat. 经理没发表讲话，因为他喉咙痛。
- She didn’t call you because she loved you. 这个句子可能出现两种理解：
A. 她给你打电话并非因为她爱你。（发生了否定转移）
B. 她没给你打电话是因为她爱你。（未发生否定转移）
到底哪种理解正确，我们无法从逻辑意义上进行辨别，这时我们只有借助语境即上下文来分析了。
not…because…这一结构中的 not 有时否定主句,有时否定从句,一般要根据句子的意思作出正确或合乎逻辑的理解.若not否定主句,最好在because之前用逗号,否则会引起歧义,如下句在没有特定上下文时就有两种解释.如：I didn’t go because I was afraid. (1) 我没有去是因为怕. (2) 我不是因为怕才去.
不过若because之前有just修饰,一般认为not 是否定从句而不是主句.如： You shouldn’t get angry just because some people speak ill of you.你不要因为有人说你坏话而生气. He was not ready to believe something just because Aristotle said so.他并不只是因为亚里士多德说过如何如何,就轻易相信它.
八、表示信念、看法、愿望的名词充当主语从句的表语时，形式上否定谓语，语义上否定主语从句。这类词有：hope, thought, view, opinion , wish, expectation, belief, plan等。
- It is not our expectation that you will suffer a lot from that. (will not suffer … )
我们希望你不要为那事受太多苦。
- It is not my opinion that you spend much time on computer games. (do not spend … )
我的看法是你不要花太多时间玩电脑游戏。
- It is not their plan that their homework is done on Sunday. 他们计划星期天不做家庭作业。
九、含有全体意义的代词和副词作主语或宾语时，形式上否定谓语，语义上否定主语或宾语，表示部分否定。这类词有：all, both, every, everybody, everything, everywhere, always, altogether, entirely，wholly。
- All the people didn't know the truth. (Not all the people knew the truth.)
并非所有的人都知道事情的真相。
- All that glitters is not gold. 发光的不总是金子。
- Both the children are not clever. (Not both the children …) 两个孩子并不都聪明。
- Everybody, it is true, wouldn’t like it. ( Not everybody …) 的确不是人人都喜欢它。
- I don’t know all of them. (no tall of them) 对于他们我不是个个都认识的。
- I don’t like both of them. (not both of them.) 这两本小说，我不是都喜欢。
注：当all 与can not 或 won’t 构成否定句式时，其否定不再发生转移，而表示全部否定。
- All the foreigners can not pass the borders without visas. 所有外国人没有签证均不能过境。
- All the treatment won’t make any help for her disease. 所有的治疗对他的疾病都无用。
十、"否定主句 肯定式方式从句" 中，主句和从句意思正好相反。例：
- Whales are not fish, as many people think. 鲸不是鱼，而许多人却认为鲸是鱼。
十一、主语是否定特征时，翻译应根据具体情况确定。否定可以转移，也可以不转移。例：
- Nobody who has ever seen good-quality color television can ever be completely happy with black and white again. 看过高质量彩色电视的人再也不可能对黑白电视感到满足了。
知识拓展：
英语句子中，在下列情况下通常要用到否定转移，即否定形式要放在前面的主句里。 1、在主句动词是 think, believe, suppose, expect, fancy, imagine 等的时候.。 I don't think I know you. 我想我并不认识你。 I don' t believe he will come.我相信他不回来。 注意：如果主句动词是hope, 则宾语从句中的否定词不能转移。 I hope you weren't ill.我想你没有生病吧。 2、主句动词是seem, appear 等。 It doesn't seem that they know where to go.看来他们不知道往哪去。 It doesn't appear that we'll have a sunny day tomorrow.看来我们明天不会碰上好天气。 3、主句否定的是后面的动名词、介词短语。 I don't remember having ever seen such a man.我记得从未见过这样一个人。 (not否定动名词短语 having…) It's not a place where anyone would expect to see strange characters on the street.在这里，人们不会想到在街上会碰上陌生的人。(anyone 作主语，从句中的谓语动词不能用否定形式。) 4、主句否定的是后面的状语或状语从句。 The ant is not gathering this for itself alone. 蚂蚁采食不只是为自己。(否定状语) He was not ready to believe something just because Aristotle said so.他并不因亚里斯多德说过如何如何，就轻信此事。(否定because状语) She had not been married many weeks when that man's younger brother saw her and was struck by her beauty. 她结婚还不到几个月，这个人的弟弟就看见她了，并对她的美貌着了迷。 (否定状语many weeks)
讲了这么多，总结一下，是不是否定转移要根据上下文看是否符合逻辑为原则，与主语和谓语没有必然联系，只是常用情况给我们造成有规律的假象。
