please look at the clock改为否定句
please look at the clock改为否定句介绍如下：
Please don't look at the clock.
否定句英语修改：
1、句中有be动词的，在be动词后加not。
2、句中有情态动词的（can，should，must，would），在情态动词后面加not。
3、句中没有be动词和情态动词的，在动词前加don’t或doesn’t。
4、肯定句中的some在否定句中应改为any。
没有前面几种情况的，要用到助动词do、does、did加not，放在动词原形前面；特别情况，有些句子本身有不定代词做主语或者宾语了的，把不定代词改为否定即可。
肯定陈述句中本来是没有助动词的，要加上去，位置在主语(某人或某物)后，动词前。确定助动词用do、does还是did，根据句中动词，动词是原形的助动词就用do，动词是第三人称单数的助动词就用does，动词用过去式的助动词就有did。在助动词后加not。原句中动词假如发生变化就要恢复成原形。
否定句例子：
1、I don't know this. No news is good news.
这个我不知道。没有消息就是好消息。
2、There is no person（smoking）/not a person/not any person（smoking）in the house.
房子里没有人在抽烟。
3、He went to his office, not to see him.
他去了他的办公室，不是去看他。
4、I am sorry for not coming on time.
很抱歉我没有准时来。
5、I don't think / believe/suppose / feel / imagine you are right.
我认为/相信/假设/感觉/想象你是不对的。
6、All the answers are not right.
并非所有的答案都是对的。
7、All is not gold that glitters.
闪光的不全是金子。
店豪立复： 不正确,应该是please look at it,look为不及物动词,应加介词
科尔沁区17839991754： please look the tree还是please look at the tree - ？
店豪立复： 应该是please look at the tree 通常来说,look是一个不及物动词,后面不能直接添加宾语,所以仅仅表示“看”.如果想要表达“看某物”“,那么就应该在look后添加介词at,look at是及物动词短语,后面必须有宾语.eg. Don't look around when having a talk with others. Look at the picture.

店豪立复： Please have a look at it.的语法look和look at的区别 Look是一个不及物动词,如果后面跟宾语的时候,要加介词at,后面没有宾语的时候就不用介词.比如:I have a beautiful picture.Please have a look(at it). have a look at后面要加宾语 have a look一般放在句尾,后面什么也不加,后面加上at这个介词后,一定要再跟一个介词宾语. I just have a look.我就看一看. I just have a look at these shoes. 我就是看一下这些鞋子.
科尔沁区17839991754： Please look at the blackboard and don't read... - ？
店豪立复： and连接两个祈使句,所以直接以动词原形开头,一般是省略了主语,完整的句子可以补充 You look at the blackboard please.You don't read... please的用法(1) please 动词:“请” please + V原形 (无论放在句首还是句中) Eg: Would you ...
科尔沁区17839991754： 英语please look at the blackboard 中为什么介词要填at? - ？
店豪立复： Please look at the blackborad.请看黑板. 必须要加at,因为at和look是词组,意思是:看. 同义词:Have a look. 例句:1、This way,please.Thank you.这边请.谢谢!2、I'm drawing a picture.Have a look!我正在画画,看!
科尔沁区17839991754： Please look at that picture是什么意思为什么要用at下去 - ？

科尔沁区17839991754： Please ( )(look) at the blackboard - ？
店豪立复： 答案:Please look at the blackboard 解释:祈使句有两种形式:一、“let + me/us/them/him/her + 动词原形”构成:Let me have a look. 让我看一看.Let us (或Let's) go. 让我们走吧.Let him do it. 让他去做吧.二、其它动词原形构成1. please + 动词原形 + 其它成分,如:你的提问——Please look at the blackboard. 请看黑板.2. 动词原形 + 其它成分,+ please把上一句改动:Look at the blackboard, please.
科尔沁区17839991754： Please look at the sentence in the first paragrap - ？
店豪立复： 介词短语 in the first paragragh 是 sentence 的后置定语.短语充当后置定语相当于定语从句,所以可以改为 Please look at the sentence (which is) in the first paragragh.用 you mentioned 改变了原意,不妥.其实,多数后置定语都可以这样改,如 He is always the first to come 可以改为 He is always the first who comes.
