1、动词时态: 一般现在时Be型: I用am, you用are, is连着他她它;单数isWhat did do 过去时间?Did 主语 动词原形 过去时间?动词过去式变化规则:规则变化:①一般在动词原形末尾加ed ②词尾e的动词加d ③末尾只有一个辅音字母的重读闭音节,先双写这个辅音字母,再加ed ④结尾是“辅音字母 y”的动词变y为I,再加ed,如studied.结尾是”元音 y”的动词直接加ed,如played.动词过去式 ed的读音：①在浊辅音和元音后/d/ ②在清辅音后面/t/ ③在/t/ /d/ 的音后面发/id/一些不规则动词的变化:am, is (was); are (were); have, has (had); go (went); eat (ate)buy (bought); do (did); ski (skied); make (made) see (saw) leave (left)take (took) study (studied) swim (swam) sing(sang)一般过去时态如何将肯定句变成一般疑问句?①一种是有be动词的,即有was或were,只要把was或 were 提到句首, 把句中第一人称转为第二人称，即I, we变you, my和our变your,然后把句中剩下的单词依次抄下来．如：It was a windy day.--Was it a windy day? That was my bag.---Was that your bag?②另一种是无be动词的句子，需要助动词来帮忙。
2、把过去时态的助动词did放在句首，把第一人称改为第二人称，然后把剩下的句子依次抄下来，在抄的过程中，要把动词的过去时转变成原形。
