Answer 1

过去式：
过去式是用来表达动词的“过了”、“完了”，“结束了”等意思，和现在的状态没有关系。通常与过去的时间状语连用:yesterday ,last week(month,year) be(was/were)+Ved(过去式）
概念：一般过去式 表示过去的动作和状态。
一般过去式构成： 表示一般过去式的动词通常用动词的过去式形式来表示，而动词的过去式是在动词原形的基础上变化的。动词的过去式可分为规则动词和不规则动词。规则动词的过去式变化
be动词的过去式：are——were am，is——was
如下：
一般情况下，动词词尾加 -ed ，如：
worked played wanted acted
以不发音的 -e 结尾动词，动词词尾加 -d，如： lived moved decided declined hoped judged raised wiped
以辅音字母 + y结尾的动词，把-y变为-i 再加-ed，如：
studied tried copied justified cried carried embodied emptied 以一个辅音字母结尾的重读闭音节动词，双写词尾辅音字母，再加 -ed，如： stopped begged fretted dragged dropped planned dotted dripped 注：不规则动词的过去式变化规律性不强，须多加记忆。
go - went make - made get - got buy - bought come - came fly-flew
e.g:
1.It was a big day for us. 对我们来说这是重要的一天.
2.He was a bright child. 他是一位聪明的孩子。
3.Keepers said the pandas were in good condition. 饲养员说两只大熊猫的状态良好。
4.Mr. Smith went to Switzerland. 史密斯先生去了瑞士。
5.Did you play football yesterday?你昨天踢足球了吗？
6.Where were you? 你在哪？
relax relaxing relaed 区别：
relax v. 是指放松，休息。短语：relax oneself 放松自己；放松某人自己
e.g:Now I want to rest and relax.
It's a good place to relax.
而以“ing”结尾的形容词，指的是物体本身的特征。
e.g:The movie is relaxing.
This is a relaxing song.
以“ed”结尾的形容词则是指人的感受。
e.g:I’m very relaxed.
Tom is kind of relaxed.

adj. 幸福的；高兴的；巧妙的
[ 比较级happier 最高级happiest ]
