过关冲刺100分专项一一般过去时七年级英语下。
解题思路： 动词过去式的构成分规则变化和不规则变化两种形式，不规则变化通常需要逐个记忆，规则变化则遵循以下原则： (1) 一般在动词后加-ed。如：play—played, offer—offered, weigh—weighed, destroy— destroyed, sign—signed. (2) 在以字母e结尾的动词后，只加-d。如：like—liked, provide—provided, hate — hated, date—dated。 (3) 在以“辅音字母+y”结尾的动词后，则改y为i，再加—ed。如：supply—supplied, study— studied. (4) 在以单短元音的重读闭音节结尾且，末尾只有一个辅音字母的动词后，双写最后一个辅音字母，再加-ed。如：plan—planned, refer—referred, regret—regretted, ban—banned.
