ithink引导句子否定句_i think 句子变否定

1.I think it's boring的否定句 He thinks it's boring的否定句

2.肯定句变否定句20个例子英语

3.由think引导的句子的反义疑问句的回答看主句还是从句

4.把下列句子改为否定句

这是英语的一种习惯思维方法，与汉语不同，应予注意。

如果主句的谓语动词是think, believe, suppose, expect, guess, fancy, feel, imagine等表示“观点、信念、推测”等心理活动的动词时，否定谓语从句的not往往转移到主句，成为“形式否定主句，意义否定从句”。

否定转移的条件有三：　这三个条件必须同时满足，缺一不可！　

1.主语只限I和we；

2.主句谓语是一般现在时　

3.谓语动词应是think, believe, suppose, imagine, expect等。　　

I don’t imagine the meeting will take more than an hour. 我想会议不会超过一小时。　　

下列情况不用否定转移：　　

1.?当主句的主语是第二、三人称时。　　

He thinks this problem is not difficult. 他认为这个问题并不难。　　

2.当think后的宾语从句中含有not的固定词组（如can’t help, not at all, not only … but also等）时。　　

I think everybody can’t help laughing if they see it. 我想见到它都会禁不住大笑。　　

3.当think 后的宾语从句中含有 no, never, nothing, nobody.等否定词时。　　

I think noting is too difficult if you put your heart into it. 我认为只要你用心，没有什么难事。　　

4.当think 前有起强调作用的助动词（do 的适当形式）时。　　

I do think you shouldn’t go there. 我确实认为你不该去那里。　　

5.当think 和另一动词构成并列谓语时。　　

I think and hope that I’m not disturbing you too much. 我认为，也希望没太打扰你。　　

6.当think 是一般过去式或过去进行式时。　　

I thought you hadn’t caught the bus. 我认为你并没赶上那辆公共汽车。　　

7. 当think 是完成式或完成进行式时。　　

I’ve often thought high life doesn’t agree with us. 我常常认为上流社会的生活并不适合我们。　　

8. 当think 前面有副词修饰时。　　

You may be a clever man and good teacher, but I sometimes think you don’t see simplest thing that is taking place under your very nose. 你也许是个聪明人，一个优秀的老师，不过我有时认为即使就在你眼皮底下发生的最简单的事情你也不见的能看见。

2I worried that. worried ?可做使役动词即worry sb但本句不是

此处是应该为：I worried about that.但有的动介短语后面跟宾语从句时 可以省略介词

所以此处可以是I worried that

至于I‘m worriedabout that这是系表结构 介词也可以省略

再如 i hear (of) that。。。

i am afraid that.......

3.All man are welcome. 这句话应该对 welcome本身可以是形容词做表语

adj. 受欢迎的

如果是过去分词welcomed. ?改成这样 All man are welcomed。可以说是被动语态也可以说是系表结构。我认为welcome作表语与过去分词welcomed作表语并无区别，

但如果是被动语态必须用welcomed。

I think it's boring的否定句 He thinks it's boring的否定句

一、所谓否定转移，指的是某些特定的动词后面表示否定意思的宾语从句的否定词 not ，从宾语从句转移到了主句中去否定这种动词。比如——

I do not think we are defeated by ourself. 我认为我们不是被我们自己打到的。

这个句子的结构本来应该是——

主句：I think 我认为

宾语从句：we are not defeated by ourself 我们不是被我们自己打到

但是如果和在一起讲，就要把从句中的 not 转移到主句去否定 think，因此就变成了下面的形式——

主句：I do not think 我不认为

宾语从句：we are defeated by ourself 我们被我们自己打到

二、各种语言都有自己的说话习惯。像上面的意思，汉语既可以说“我认为我们不是被我们自己打到的”，也可以说“我不认为我们是被我们自己打到的”，二者除了造句方法不同外，意思上没有多大区别。但是英语则不同，只能用否定转移句 I don't think + 肯定句，不能用 I thing + 否定句。不这样讲就不符合英语的习惯，这是王八的屁股——龟腚（规定）。

三、下列常用的表示“认为”的特定动词，如果后面要带有表示否定意思的宾语从句，一律都要用否定转移句表达——

think —— 通过推理或沉思而认为

believe —— 作为真理或事实而认为

suppose —— 定为正确或真实而认为

expect —— 作为期待而认为

imagine —— 作为设想而认为

fancy —— 作为想象而认为

四、本句参考译文：我曾经认为，如果我们惹了麻烦，你可能会出现，我们可以共同战胜一切灾难。但是，我认为我们不是被我们自己击倒的。

由think引导的句子的反义疑问句的回答看主句还是从句

肯定句变否定句20个例子英语如下：

1、I think she is there.

否：I don't think she is there.

2、He can sing this song and that one.

否：He cannot sing this song or that one.

3、Tom went to school too.

否：Tom didn't go to school either.

4、He has had supper already.

否：He hasn't had supper yet.

5、He had a good rest just now.

否：He didn't he a good rest just now.

6、Let's do it.

否：Don't let's do it.或Let's not do it.

7、He always gets there on time.

否：He never gets there on time.

肯定句变否定句方法：

1、be动词的否定式。

be 动词根据不同的人称和时态有不同的形式，在一般现在时中是am , is , are可用作联系动词，构成否定式时，一律在其后面加否定词not.

He is reading.——He is not reading. They are from China. ——They are not from China.

2、情态动词的否定式。

情态动词的否定式是在其后面直接加not. 如：

I can swim. ——I can't swim. He can dance. —— He can't dance. You should go to school at seven. ——You shouldn't go to school at seven.

3、实义动词的否定句。

实义动词变否定句时，要借助助动词do , does，在一般现在时中用do或者does其句子结构为：主语+ don't / doesn't+动词原形+其它 。

把下列句子改为否定句

含有think, believe, suppose, imagine, expect等动词后接宾语从句构成的主从复合句在构成反意疑问句时，视情况不同有两种不同的构成方式。　（即当主句是I think，I believe，I

suppose，I imagine，I expect时要反问从句，其余句式均反问主句。）

(1)当主句的主语为第一人称时，其后的简短问句应与从句相一致。例如：

I expect our English teacher will be back this weekend, won't

she/he?

We suppose you he finished the project, hen't you?

值得注意的是，当这些动词后接的宾语从句的否定转移到主句时，其仍属否定句，故其后的简短问句应用肯定式，而非否定式。例如：

I don't believe that he can translate this book, can he?

We don't imagine the twins he arrived, he they?

此类句子的回答同"前否后肯"型反意疑问句一样，如上述后一个句子，若双胞胎已经到了，则回答为"Yes, they

he."；若尚未到达，使用"No, they hen't."。

(2)当主句的主语为第二、三人称时，其后的简短问句则应与主句相一致（此时，否定只看主句，与从句无关）。例如：

Your sister supposes she needs no help, doesn't she?

You thought they could he completed the project, didn't

you?

They don't believe she's an engineer, do they?

She doesn't expect that we are coming so soon, does she?

(3)但如果主句的时态是过去时等等，疑问句应和主句的人称时态保持一致

1、Ithink this is right。是I don't think this is right.

2、He cleaned the classroom and played football that afternoon.是He didn't clean the classroom and play football that afternoon。

3.You should（你漏了一个字母吧） drink something before you go to see the doctor.是You shouldn't drink anything before you go to see the doctor。

希望帮到你。。。。。但是不知道对不对。。忘了快
