初一英語上冊語法匯總
要想取得好的學習成績,必須要有良好的學習習慣。習慣是經過重復練習而鞏固下來的穩(wěn)重持久的條件反射和自然需要。下面是小編為大家精心整理的初一英語上冊語法匯總,希望對大家有所幫助。
動詞
A) 第三人稱單數
當動詞是第三人稱單數時,動詞應該像名詞的單數變動詞那樣加s,如下:
一)一般在詞后加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)以輔音字母加y結尾的變y為i再加es。如:study-studies, hurry-hurries, try-tries
2)以元音字母加y結尾的直接加s。如:plays, says, stays, enjoys, buys
四)以o結尾加es。如:does, goes
五)特殊的有:are-is, have-has
B) 現在分詞
當我們說某人正在做什么事時,動詞要使用分詞形式,不能用原形,構成如下:
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)以不發(fā)音e的結尾的去掉e再加ing。如:dance-dancing, wake-waking, take-taking, practice-practicing, write-writing, have-having
三)以重讀閉音節(jié)結尾且一個元音字母+一個輔音字母(注意除開字母組合如show –showing, draw-drawing)要雙寫最后的輔音字母再加ing。如:put-putting, run-running, get-getting, let-letting, begin-beginning
四)以ie結尾的變ie為y再加ing。如:tie-tying系 die-dying死 lie-lying 位于
特殊情況:(兩好多壞,一少老遠)
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
單數句變復數句
1. 可數名詞單數要變?yōu)槠湎鄳膹蛿敌问健?/p>
It is a box.→ They are boxes.
2. 各個人稱代詞要由單數形式變?yōu)閺蛿敌问健?/p>
She is a girl.→ They are girls. I am at home.→ We are at home.
3. am或is 要變?yōu)閍re.
He is a teacher. → They are teachers.
4. 指示代詞this或that要分別變?yōu)閠hese或those。
This is a pencil.→ These are pencils.
5. 不定冠詞a/an要去掉(固定搭配例外)。
It is a black cat.→ They are black cats.
6. man或 woman做定語修飾可數名詞,在整個句子變成復數的情況下也要變成 men或women.
She is a woman teacher.→ They are women teachers.
注意:在單數句變復數句時,普通單數變?yōu)閺蛿敌问剑斆~修飾名詞時,起修飾作用的名詞不做變化。名詞修飾名詞常用單數。(man, woman除外)
