人至贱则无敌上一句,七年级上册英语语法句子

谢谢采纳：
当动词是第三人称单数时，动词应该像名词的单数变动词那样加s，如下： 一）一般在词后加s。如：comes, spells, waits, talks, sees, dances, trains
二）在x, sh, ch, s, tch后加es。如：watches, washes, wishes, finishes
三）1）以辅音字母加y结尾的变y为i再加es。如：study-studies, hurry- hurries, try-tries
2）以元音字母加y结尾的直接加s。如：plays, says, stays, enjoys, buys
四）以o结尾加es。如：does, goes 五）特殊的有：are-is, have-has B） 现在分词
当我们说某人正在做什么事时，动词要使用分词形式，不能用原形，构成如下：
一）一般在后加ing。如：spell-spelling, sing-singing, see-seeing, tra in-training, play-playing, hurry-hurrying, watch-watching, go-going, do-doing
二）以不发音e的结尾的去掉e再加ing。如：dance-dancing, wake-waking, take-taking, practice-practicing, write-writing, have-having 三）以重读闭音节结尾且一个元音字母＋一个辅音字母（注意除开字母组合如 show –showing, draw-drawing）要双写最后的辅音字母再加ing。如：put-p utting, run-running, get-getting, let-letting, begin-beginning 四）以ie结尾的变ie为y再加ing。如：tie-tying系 die-dying死 lie-lying 位于 16、句式 1）陈述句
