氧化铜化学式:否定句中连词and和or的区分

and 和or

并列连词and 和or的具体用法吗?请悉心关注他们的自传

[Mr And ] Hi , everyone!我是并列连词中的老大,人称Mr And, 我的基本意义为\"和, 又, 而\",我的工作就是专门连接并列的单词、词组、短语或句子,起承上启下的作用。我用在句子开头的时候,一般不译出来。同学们要注意的是:我所连接的词语或句子属于并列关系,前后是没有任何矛盾的。如:

Tom and David are in the same class.汤姆和大卫在同一班。

Let\'s go and see, OK? 咱们去看看,好吗?

I bought Granny a present, and she liked it very much. 我给奶奶买了件礼物,她非常喜欢。

同学们,记住我的用法了吗?Let\'s be good friends. See you next time!

[Mr Or ] Hi, boys and girls! 我是Mr Or, 别看我体型小,作用可大啦!我也是并列连词的一员,排行老三,表示\"或者\"的意思,我也用于连接并列的单词、词组、短语或句子,但是,我在用法上要比我的大哥灵活,我的用法如下:

1.连接并列的单词、词组、短语或句子,表示\"或者\"的意思。如:

We can visit the World Park or travel around the world. 我们可以参观世界公园,或者周游全世界。

2.用在选择疑问句中,灵活译为\"还是\"。如:

Is that an apple or an orange?那是苹果还是桔子?

3.否定句中,我代替我的大哥and ,表示\"和\"的意思。如:

I don\'t like bread , rice or porridge.我不喜欢面包、米饭和粥。

4.连接两个并列的句子,表示\"否则,要不然\"的意思。如:

Hurry up, or you\'ll be late.快点,否则你要迟到啦。

同学们,Let\'s be good friends, OK? See you soon.

人家问得是否定句中的and和or的区别阿！

我的理解：
or,在否定句中就是“既不是...也不是...”的意思。
比方：He is not American or British, he is French.（他不是美国人，也不是英国人，他是法国人。）
在这种情况下，not A or B,是把A和B分别否定掉。

而not A and B则是把A和B作为一个整体否定掉。
比方：-Do you see an apple and an orange in the basket?（你看见篮子里有一个苹果和一个橙子么？）
-No,they are not an apple and an orange. They are two pears.（不，那不是一个苹果和一个橙子，那是两只梨。）

否定句中连词and和or的区分
AND是 和, OR是 或者(选择一个)

I don't want to go to Beijing University or Nanjing University. Instead, I want to go to Fudan University.
Since you can attend only one university, you should use "OR", even you don't want any one of them.

I don't want to go to Beijing and Nanjing this Summer for my vocation. Instead, I want to go to Xian and Luoyang.
In this case, Beijing and Nanjing are conbined together as a Summer trip. So you should use "AND" to deny both of them.

Give you another pair of examples:

I don't want to marry Lisa or Jane.
(But, if you wanted you would have to choose one of them to marry.)
I don't want to marry Lisa and Jane.
(Now, if you wanted you would have two wives!)

Is that clear?
