7A Unit 7 Fun after school 语法知识总结及过关练习
一、动词过去式的变化
1. be词的过去式： am /is 的过去式为was; are的过去式为were
注：be动词有人称和数的变化，主语为单数用was, 主语为复数用were
二、动词过去式的变化
2. 规则动词的过去式
a. 一般情况下，在动词原形后面加-ed。
look→looked play→played start→started
b. 以不发音e结尾的动词，在词尾直接加-d。
live→lived use→used
c. 以“辅音字母+ y”结尾的动词，先将 y 改为i ,再加–ed。
study→studied try→tried fly→flied
d. 以重读闭音节（即辅音＋元音＋辅音）或r音节结尾,末尾只有一个辅音字母的动词，
要先双写辅音字母，再加–ed。
stop→stopped　　plan→planned prefer→preferred
不规则动词的过去式是需要记忆的。
