初中必背过去式过去分词
一、原形、过去式和过去分词的词形和读音都相同的单词,结尾字母一般是t或d。如:
cut-cut-cut, hit-hit-hit, put-put-put, cost-cost-cost, let-let-let, shut-shut-shut, set-set-set, hurt-hurt-hurt, spread-spread-spread 特殊:动词read的过去式和过去分词虽然词形与原形一致,read-read-read,但发音分别是[ri:d]-[red]-[red]。
二、有些动词的过去分词与原形是一样的。如:
come-came-come, become-became-become, run-ran-run, overcome-overcame-overcome 三、有些动词的过去式和过去分词相同。如:
1. 把单词结尾的字母d改为t。如:
lend-lent-lent, spend-spent-spent, send-sent-sent 2. 改变单词中间元音字母。如:
sit-sat-sat, win-won-won, shine-shone-shone, hold-held-held 3. 以eep结尾的动词,把eep改为ept。如:
keep-kept-kept, sleep-slept-slept, sweep-swept-swept 4. 过去式和过去分词都以augh或ough结尾的动词。
