5、音字母加y结尾的词,变y为i再加“-es ”,如:baby-babies, country-countries, family-families等;4)部分以f (e)结尾的词,变f (e)为“ves ”,如:knife-knives, half-halves等;5)以o结尾的词,加“-s ”或“-es ”,如:zoo-zoos, photo-photos, tomato-tomatoes, potato-potatoes等。记忆口诀:除了“英雄”hero外,凡是能吃的,加“-es ”,不能吃的加“-s ”。2、不规则变化:1)改变单数名词中的元音字母:man-men, woman-women
6、, foot-feet, tooth-teeth等;2)单、复同形:sheep-sheep, Chinese-Chinese, Japanese-Japanese等;3)其他形式:mouse-mice, child-children等。新人教版七年级上册英语知识点:简单句的成分及主谓一致原则最基本构成:主语+谓语+宾语,其中谓语由动词来充当。主谓一致原则,就是句子的谓语要始终与主语保持数量上的一致性。当主语是第三人称单数(简称“三单”)时,谓语动词也要相应变成单数形式;当主语非“三单”时,谓语动词就用原形。实意动词变“三单”的规则如下:1)一般动词在词尾加“-s ”,如:like-likes,
7、 tell-tells, play-plays等;2)以字母s, x,ch, sh结尾的动词加“-es ”,如:guess-guesses, teach-teaches, watch-watches等;3)以o结尾的动词一般加“-es ”,如:do-does, go-goes等;4)以辅音字母加y结尾的动词,先变y为i,再加“-而是”,如:fly-flies, carry-carries等;5)have的三单形式是has。新人教版七年级上册英语知识点:冠词的用法(名词前面必须要有冠词)冠词分为定冠词(the)和不定冠词(a, an)两种。1、定冠词the表示“特指”,可译为“这个”、“那个”、
8、“这些”、“那些”。2、不定冠词a, an用来表明(可数)名词的数量是“一个”。an用于以元音开头(注意不是以元音字母开头)的单词前,a则英语非元音开头的单词前。3、不定冠词a, an与基数词one的区别是:不定冠词不是刻意强调“数量”,而基数词则强调“数量”。新人教版七年级上册英语知识点:助动词(do, does )的用法只有实意动词作谓语时才涉及使用助动词。以like为例:1)当句子为肯定句时不涉及使用助动词,只涉及“主谓一致”原则。eg : I like English a lot.Michael likes Chinese food very much.2)当句子为否定句时,要根据主语
9、的人称来决定使用相应的助动词:当主语为“三单”时,要使用does;当主语为“非三单”时,用助动词原形do。例如把下列句子变否定句:Kangkang likes math.-Kangkang doesnt like math.They like sports.-They dont like sports.3)当句子变疑问句时,同样要根据句子的主语来决定在句首使用Do或Does.例如下列句子变问句:Michael likes Chinese Food.-Does Michael like Chinese food? Yes, he does./ No, he doesnt.Jane and Hel
