(3) 以辅音字母+y结尾的词变y为i再加-es try - tries，carry - carries (4) 特殊变化的词 be (是) - am, is, are I am
she/he/it, 名词单数都用 is we, you, they, 名词复数都用are have (有) - have, has
I, we, you, they, 名词复数都用have she/he/it is, 名词单数都用 has
(5) 助动词，不论单复数、不论什么人称都没有变化，都用 can, may, must, need,
ought to 等。而且，句子中有了助动词，谓语动词就不需要有任何变化了，即用动词原形表示。如： We can see some pictures on the wall. 我们能看到墙上的画。 *一般过去时动词变化规则
1．直接加ed，如：work—— worked 如：look——looked
2．以不发音e结尾的单词，直接加d，如：live ——lived hope——hoped use——used
3．以辅音字母+y结尾的，变y为i加ed，如：study—— studied carry——carried
worry——worried（原因字母+y结尾，直接加ed, 如：play-played） 4．以重读闭音节结尾的，双写最后的辅音字母+ed，如：stop—— stopped
plan——planned 重读闭音节体现形式为辅-元-辅结构，例如nod,n为辅音，o为元音，d为辅音。 5. 以ic结尾的动词，要把ic变成ick再加ed，如：picnic→picnicked，traffic→trafficked
6．不规则变化的动词过去式：
have---had are---were get---got say---said feel---felt
do/does---did is---was go---went drink--drank eat--ate bring----brought think----thought buy----bought catch---- caught teach ---- taught sit----sat wear----wore cut----cut sweep----swept sleep——slept see----saw become----became *动词加ing（现在分词）的变化规则
（1）一般情况下，直接加ing，如：look - looking, climb - climbing, jump - jumping （2）以不发音的e结尾，去e加ing. 如：make - making, have - having, ride - riding,
(see的e是发音的，所以不能去掉，要直接加ing。see - seeing )
（3）如果末尾是一个元音字母和一个辅音字母，并处于重读音节中，双写末尾的辅
音字母，再加ing.如：run - running, swim - swimming, sit - sitting, (但是open却不属于这规则，而是直接加ing， open-opening) 注意：
（1）某些表示思想，感情，态度和状态等的动词
如:belive,think,know,understand,want,love,like,see,hear,smell,taste,等，不用现在进行时。
（2）有些动词可以用现在进行时表示将来，如：go，come，leave，stay，start，begin, arrive等，eg. She is arriving at about ten o?clock tomorrow. 她大约会在明天早上十点钟到达。
*现在完成时和一般过去时的区别
1.一般过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作：现在完成时为过去发生的，强调过去的事情对现在的影响，强调的是影响。 试比较：
① Who has opened the door? 谁把门开了？（现在门还开着）
Who opened the door？ 谁开的门？ （指过去，与现在无关，现在门是关着还是开着，没有说明）
②Have you had your lunch? 你吃过午餐了吗？（即你现在不饿吗？） Yes，I have. 吃了。（即我现在饱了，不要再吃了） When did you have it? 你什么时候吃的？
（说话人感兴趣的是“吃”这一动作发生在过去的什么时候。）
2.过去时常与具体的时间状语连用: 现在完成时通常与模糊的时间状语连用，或无时间状语。
一般过去时的时间状语:yesterday, last week, ago, in 1980, October, just now等具体的时间状语
共有的时间状语：this morning，tonight，this April，now, once, before, already, recently, lately
现在完成时的时间状语：for，since，so far, even, never ,just, yet, till/ until, up to now, in past
years,等不确定的时间状语

学习任务：掌握被动语态及非谓语动词的用法 (一) 被动语态
