初一英语上册语法汇总

    要想取得好的学习成绩，必须要有良好的学习习惯。习惯是经过重复练习而巩固下来的稳重持久的条件反射和自然需要。下面是小编为大家精心整理的初一英语上册语法汇总，希望对大家有所帮助。
    动词
    A) 第三人称单数
    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, train-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-putting, 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
    特殊情况：(两好多坏，一少老远)
    good/well - better best many/much - more most bad/ill – worse worst
    little- less least old- older/elder oldest/eldest far- farther/further farthest/furthest
    单数句变复数句
    1. 可数名词单数要变为其相应的复数形式。
    It is a box.→ They are boxes.
    2. 各个人称代词要由单数形式变为复数形式。
    She is a girl.→ They are girls. I am at home.→ We are at home.
    3. am或is 要变为are.
    He is a teacher. → They are teachers.
    4. 指示代词this或that要分别变为these或those。
    This is a pencil.→ These are pencils.
    5. 不定冠词a/an要去掉(固定搭配例外)。
    It is a black cat.→ They are black cats.
    6. man或 woman做定语修饰可数名词，在整个句子变成复数的情况下也要变成 men或women.
    She is a woman teacher.→ They are women teachers.
    注意：在单数句变复数句时，普通单数变为复数形式，但当名词修饰名词时，起修饰作用的名词不做变化。名词修饰名词常用单数。(man, woman除外)
    This is a apple tree.→ These are apple trees.
