  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

  17、代词
  代词是代替名词的一种词类。大多数代词具有名词和形容词的功能。代词在英语中的使用是很频繁的,这是因为在英语语言习惯中,第二次提到一些名词时,一般用代词代替这些名词。英语中的代词,按其意义,特征以及在句子中的作用可分为人称代词、物主代词、指示代词、反身代词、关系代词和不定代词。 1)不定代词 、One的用法
  一般是指人或物,在句中可做主语、宾语和定语。
  One should try one’s best to serve the people. (指人) 一个人应该尽最在努力为人民服务。
  A:-----Look at that boy!看那个男孩!B: Which one? 哪一个?

  A:-----The one wearing a blue sweater. 穿蓝色毛衣的那个。
  Which boxes are bigger , these ones or those ones?哪些盒子更大一些,这些还是那些?(指物) ② some和any
  1、在肯定句中用some.例如: There are some books on the desk.桌子上有一些书。 Lucy has some good books露西有一些好书。
  2、在疑问句和否定句中用any。例如: Is there any ink in your pen?你的钢笔里有墨水吗? Do you have any brothers and sisters?你有兄弟姐妹吗? There isn't any water in the glass.杯子里没有水。 ⑵记住它们的特殊用法。 ①some亦可用于表示盼望得到对方肯定的答复或表示建议、委婉请求的疑问句中,这一点我们不久就会学到。例如: Would you like to have some apples?你想吃苹果吗? 3、any也可用于肯定句中,表示"任何的"。例如: Any one of us can do this.我们当中任何一个都能做这个。 some 和any的用法是经常出现的考点,希望大家能准确地掌握它们的用法。 2、人称代词和物主代词 人称代词指代人或物,在句中作主语或宾语,所以有主格和宾格。
  宾格代词用于替代处于宾语位置上的名词,可以用作直接宾语和间接宾语。 例如:I am a student. (I 主语)
  Please help me. (me 直接宾语) Give me a book. (me 间接宾语)
  物主代词是表示所有关系的一种代词,亦称所有格代词。物主代词有两种形式:形容词性物主代词和名词性物主代词。
  形容词性物主代词为限定词,放在名词或名词短语前作定语。 如:This is my book.
  名词性物主代词起名词的作用,后面不可以再接名词。在句子中可以作主语、宾语或表语。
