关于基数词和序数词 I. 基数词表示数目和号码, 如： : The population of this city is one million and three hundred thousand. His phone number is 89276310. The live at 12, Bill Street. II. 序数词表示顺序，如： Take the second right. They live on the third floor. III. 注意下面基数词变为序数词的不规则变化： onefirst, twosecond, threethird, fivefifth, eighteighth, nineninth, twelvetwelfth IV. 注意下面十位数基数词变为序数词的不规则变化： Twentytwentieth, thirtythirtieth, fiftyfiftieth,四以上加th,八减t (eighth),九去e(ninth), f来把ve替，ty须变tie. 若是碰到几十几，改变个位就可以。,第三人称的写法：,1、多数动词后面加-s.,2、以字母o,s,x,ch,sh结尾的动词后面加-es. 如do-does miss-misses catch-catches push-pushes,3、动词末尾-y前为辅音时，则变-y为-i，再加-es.如cye-cyies 但在动词末尾的-y前为元音时，则只加-s，如buy-buys,(这种变化与名词的单数变复数有点相像 ）,那么，什么情况下用行为动词的一般现在时呢？当这个动作经常发生或表示习惯性的动作时，通常用一般现在时，它经常与表示频度的时间状语连用，如，当句子中有every day every year ,on Sunday, in the morning ,often, sometimes, usually, at one oclock,等词时，用一般现在时。 He gets up at 6 oclock. She usually watches TV in the evening. Sometimes he goes to school by car. Tom often flies a kite on Sunday.,只有第三人称单数动词才要变， 其他人称（I,you ,we ,they）则用动词的原形。,写出下列动词的正确形式： 1、I (go) to school at seven in the morning. 2. Mike ( do) his homework at eight in the evening. 3. His father often ( read) books in the library on Saturday. 4.My mother usually (watch) TV plays at home. 5.
