动词过去式的构成
1. 规则动词：
– 一般现在时态的动词（如：go, study, play）通常以辅音字母+y结尾，将y改为i加e再加ed。
– 不规则动词（如：have, do, be）不遵循上述规则，需要根据具体单词来判断。
2. 不规则动词：
– 例如：have → had, do → did, be → was, see → saw, hear → heard, say → said, think → thought, know → knew, have → has, make → made, go → went, read → read, write → wrote等。
3. 不规则动词的不规则变化：
– 有些动词的过去式和过去分词形式会发生变化，这取决于动词本身的性质。
– 例如：become → became, become → becoming, begin → began, begin → beginning, continue → continued, continue → continuing, end → ended, end → ending, finish → finished, finish → finishing, get → got, get → getting, keep → kept, keep → keeping, make → made, make → making, pass → passed, pass → passing, put → put, put → putting, return → returned, return → returning, start → started, start → starting, stop → stopped, stop → stopping, take → took, take → taking, throw → threw, throw → throwing等。
