in表示一段时间，用在年、月、星期（周）、四季、morning、afternoon、evening前，但当morning，Sunday等前有this，that，next，last时就要省去in。

学过的语法：1、一般过去时:动作发生在过去，现在已经结束了。

从句子中过去的时间和动词的过去式可以看出是过去时。

过去的时间就用动词的过去式。

如：I was happy last Sunday. am 的过去式过去的时间2、一般将来时：动作发生在将来。

一般句子中会出现将来的时间和will, will要加动词原形。

如：It will be rainy tomorrow. It will rain tomorrow.3、一般现在时：经常性的动作或者一种状态。

主语是第三人称单数（she, he, it…）时动词要用第三人称单数形式，通常与always，often，usually，sometimes等词连用。

如：I usually have lunch at twelve. 单三I like swimming. 单三形式He usually has lunch at twelve. 单三He likes swimming. 单三形式一般情况下：(1)第三人称单数形式就是在词尾加s;(2)以s, x, ch, sh,“O”结尾的加es;(3)辅音字母加y的，y变i再加es;另外，不规则的有：have—has,do---does等.like—likes, watch---watches, fly---flies 4、现在进行时：动作正在进行。

be动词+动词的现在分词------即am，is，are+动词+ing 注意加ing的方法有：（1）直接加，如：play---playing （2）去e加，如：take---taking（3）双写加，如：sit---sitting, stop—stopping, begin—beginning swim—swimming, hop—hopping, skip—skipping, forget—forgetting, travel—travelling, run—running例句：I am swimming. He is running. What are they doing?5、形容词和副词的比较级(-er)是两者比较，最高级(-est)是三者以上比较。

形容词的最高级前要加the。

比较级：You are a month older than me.最高级：He is the tallest boy in his class. He jumps highest of the three.6、序数词的用法以及与年月日相关的句型。
