How was your school trip? 重难点突破

规则变化

一般情况直接在动词原形后加-ed,如：want—wanted,　need—needed等

以不发音的e结尾的动词，词尾直接加-d，如：live—lived,　move—moved等

以“辅音字母+y”结尾的动词，把y变i，再加-ed,如：study—studied,　carry—carried等

是重读闭音节且末尾只有一个辅音字母的动词，要双写该辅音字母再加-ed，如:stop—stopped,　rob—robbed等。

不规则变化

有些单词需特殊记忆，如：buy—bought, take—took，have—had, go—went,　eat—ate,　see—saw,　is(am)—was, are—were,　do—did,　come—came等
