表示时间，注意以下用法：
① 表示时间的某一点、某一时刻或年龄等用 at：
I get up at six in the morning. 我早上六点钟起床。
He got married at the age of 25. 他 25 岁结婚。
② 泛指一般意义的上午、下午或晚上以及月或年等较长的时间，一般用 in：
We watch TV in the evening. 我们晚上看电视。
He went to Japan in 1946. 他于 1946 去了日本。
③ 若表示星期几或某一特定的日期，则用 on：
He left here on the fifth of May. 他于 5 月 5 日离开这儿。
表示地点、场所、位置等，注意以下用法：
① 表示某一点位置，用 at：
We live at No. 87 Beijing Road. 我们住在北京路 87 号。
The hospital is at the end of the street. 医院在这条街的尽头。
与名词所有格连用表示地点，也用 at。如：
at my sister’s 在我姐姐家
at the doctor’s 在医务室
② 表示空间或范围，用 in：
What’s in the box? 这盒子里有什么?
He lives in Paris with his wife. 他同他妻子住在巴黎。
但有时两者可换用：
The meeting was held at [in] the hotel. 会议在宾馆举行。
③ at 与 in 的另一个区别是：at 多用于指较小的地方，而 in 多用于指较大的地方：
in Shanghai 在上海
at the station 在车站
④ 介词 on 用于地点，主要指在某物的表面：
What’s on the table? 桌上有什么?
There’s a wallet lying on the ground. 地上有个钱包。
在少数搭配中，也用介词 on：
He works on a farm. 他在农场工作。
在某些搭配中，三者的区别与英国英语和美国英语有关：
in the street / on the street 在街上
in the road / on the road 在路上
in the team / on the team 在这个队
at the weekend / on the weekend 在周末
at weekends / on weekends 在周末
有时三者的差别与搭配习惯和用法有关：
in bed / on the bed 在床上
in the tree / on the tree 在树上
举例关于at、in、on的语法句子
shout at sbbe angry at sth at the age ofat that timein commontake part inin the tree（在树上，指本身不属于树的东西藏在树里面了。
比如人或动物爬到了树上。
）in order to be in for sthin and outbe interested intake an interest indo well in have it in for （挟嫌报复）depend on（依赖）from now on（今后）and so on （等等）on and on（不停地）spend some time doing sth
用 AT ON IN IN ON 组成句子 一问一达
我先只回答on in at用于时间前面，这是中考最常考的考点，初中必学：第一阶段 ： at+点时间，最小的时间 就是几点几分，比如7:00-at seven，比如9:15-at a quarter past nineon+天时间，比点时间大 就是哪一天，比如2008年8月8日-on August 8th, 2008，比如在星期一-on Mondayin+短时间，最大的时间，是指一个时间段，什么几天啦，几星期啦，几个月啊，几年啦，还有在春夏秋冬四个季度啦，比如in spring第二阶段：（三长两短）“三长”指3个长单词（moring,afternoon,eveving），他们前面用in the，比如：in the morning,in the afternoon,in the evening＂两短＂指2个短单词（night,noon），他们前面用at，比如at noon,at night第三阶段：（“三长两短”被修饰）是指moring,afternoon,eveving,night,noon这5个单词，只要被修饰，不管是“星期一的早晨”，“晴朗的早晨”，总之被修饰了，都用on，比如on Monday morning，比如on a sunny morning。
记住这三个阶段，就彻底搞定了中考以下阶段所有at on in+时间的考试！！！啊哈啊哈！再回答你第二个问题was和were我们首先要认识一个动词be，这个单词叫“be动词”，可是他想孙悟空一样，会变脸。
在一般现在时里面，他变成3个样子“am is are”，这是第一步变化；在一般过去时里面，他又从刚刚的3个样子变成2个样子，这里是第二步变化哦。
具体怎么变呢：把am 和is变成was，把are变成were。
这样我们就可以回答你的问题了，我们先观察“He at school yesterday”，现在肯定是要填入be动词的相应形式啦，首先看如果是一般现在时我们在He 后面用哪个单词啊，显然是is嘛，那么第二步，我们变成一般过去时要把is变成什么呀，显然是was喽，所以这么说你理解了么？接着第三个问题Two cats are running along the wall.你先早个句子“我正站在桌子上” 怎么造？是不是“I am standing on the desk”。
这就好办啦！我们把“我正在站”换成“两只猫正在跑”，那就是Two cats are running。
我们把“在桌子上”换成“沿着墙”，那就是along the wall。
along是“沿着”的意思。
你懂了么？哇咔咔~
at,in在句子同时出现先写哪个？

高考英语作文常用句子
开头，如果是外出类的，可以先说这次活动多么有意义，在结尾就说，我们参加了一次很好的活动，我们的心情非常高兴。
固定的句型：时间，人物 took part in/participated in/joint/attended/organized 活动（名称），which is one of the most meaningful, unforgettable and impressive things that we/I have ever done.结尾：I firmly believe that nothing is more important than to 参加活动（做某事）.上面的两种句型一般是指外出的，以记叙文为主。
那么如果是议论文的话，可以在开头说，There is a heated discussion over ..., about which the whole class are holding two different opinions. 至于结尾的部分，一般需要给出作者自己的观点，最后一句话通常可以说Therefore, I believe that the former/latter is surely a wise choice.在高考英语写作中，除了记叙文和议论文之后，还有一种就是应用文，不过在题目中，应用文的第一句一般已经给出，而最后一句就是那些什么Best wishes这样的话，所以这个就没有什么固定的句型了啊。
最后一种问题是说明文，在高考英语写作中基本上没有出现过。
收英语作文常用的短语,句型
Consequently, to solve the problem, some measures should be taken. 万能公式： 1.开头万能公式一： 名人名言有人问了，“我没有记住名言，怎么办？尤其是英语名言？”，很好办：编！原理：我们看到的东西很多都是创造出来的，包括我们欣赏的文章也是，所以尽管编，但是一定要听起来很有道理呦！而且没准将来我们就是名人呢！对吧？经典句型：A proverb says, “ You are only young once.” （适用于已记住的名言）It goes without saying that we cannot be young forever. （适用于自编名言）更多经典句型：As everyone knows, No one can deny that… 2.开头万能公式二： 数字统计原理：要想更有说服力，就应该用实际的数字来说明。
原则上在议论文当中不应该出现虚假数字的，可是在考试的时候哪管那三七二十一，但编无妨，只要我有东西写就万事大吉了。
所以不妨试用下面的句型：According to a recent survey, about 78.9% of the college students wanted to further their study after their graduation. 看起来这个数字文邹邹的，其实都是编造出来的，下面随便几个题目我们都可以这样编造： Honesty 根据最近的一项统计调查显示，大学生向老师请假的理由当中78%都是假的。
Travel by Bike 根据最近的一项统计调查显示，85%的人在近距离旅行的时候首选的交通工具是自行车。
Youth 根据最近的一项统计调查显示，在某个大学，学生的课余时间的70%都是在休闲娱乐。
Five-day Work Week Better than Six-day Work？ 根据最近的一项统计调查显示，98%的人同意每周五天工作日。
更多句型：A recent statistics shows that … 二结尾万能公式： 1.结尾万能公式一：如此结论 说完了，毕竟要归纳一番，相信各位都有这样的经历，领导长篇大论，到最后终于冒出个“总而言之”之类的话，我们马上停止开小差，等待领导说结束语。
也就是说，开头很好，也必然要有一个精彩的结尾，让读者眼前一亮，这样，你就可以拿高分了！比如下面的例子： Obviously（此为过渡短语）， we can draw the conclusion that good manners arise from politeness and respect for others. 如果读者很难“显而见之”，但说无妨，就当读者的眼光太浅罢了！ 更多过渡短语： to sum up, in conclusion, in brief, on account of this, thus 更多句型： Thus, it can be concluded that…， Therefore, we can find that… 2.结尾万能公式二：如此建议 如果说“如此结论”是结尾最没用的废话，那么“如此建议”应该是最有价值的废话了，因为这里虽然也是废话，但是却用了一个很经典的虚拟语气的句型。
拽！ Obviously, it is high time that we took some measures to solve the problem. 这里的虚拟语气用得很经典，因为考官本来经常考这个句型，而如果我们自己写出来，你说考官会怎么想呢？更多句型： Accordingly, I recommend that some measures be taken. Consequently, to solve the problem, some measures should be taken.
