1. Yu are back. 你回来了。
这句话表示说话现在的状态，用的是一般现在时态。(一般现在时态，还可以用来表达经常习惯性的动作) 常用结构：主语+动词原型+其他。特殊结构：主语（第三人称单数）+动词第三人称单数形 式+其他。例：我有一个书包。 他有一个书包。
I have a bag.
He has a bag.
2. I missed yu! 我想你了！
missed: miss的过去式, 想念
当动词变为过去式的时候，其意义和用法都不改变，仅表示这个动作发生在过去，过去式只是动词的一种形式。
动作发生在过去，就需要使用一般过去时态，这时，把原句中的动词原形变形成为过去式就可以了。
一般过去时态一般都跟表示过去的时间状语连用，如yesterday, last+时间，时间+ag等。句型结构：主语+动词过去式+表示过去的时间+其他。
例：昨天12点钟我吃了午餐。 I had lunch at 12:00 yesterday.
一般在动词词尾直接加-ed
以不发音的字母e结尾的动词，直接在词尾加-d
以“辅音字母+y”结尾的动词，先变y为i，再加-ed
以单个辅元辅字母结尾的重读闭音节动词，先双写末尾的辅音字母，再加-ed
miss — missed lk — lked
live — lived dance — danced
study — studied carry — carried
stp — stpped plan — planned
have — swim — leave — lse — meet —
3. Did yu have a nice trip? 你有一个很好的旅行吗？
这句是一般过去时中实意动词的一般疑问问，用来表示询问别人过去是否做过某事。
句型结构：Did+主语+动词原形+其他？肯定回答：Yes, 主语(代词) + did.(肯定回答)否定回答：N, 主语(代词) + did nt/didn’t. (否定回答)
