初一英語上冊語法匯總
要想取得好的學(xué)習(xí)成績，必須要有良好的學(xué)習(xí)習(xí)慣。習(xí)慣是經(jīng)過重復(fù)練習(xí)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(shù)
當(dāng)動詞是第三人稱單數(shù)時，動詞應(yīng)該像名詞的單數(shù)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(jié)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(jié)尾的直接加s。如：plays, says, stays, enjoys, buys
四)以o結(jié)尾加es。如：does, goes
五)特殊的有：are-is, have-has
B) 現(xiàn)在分詞
當(dāng)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(gòu)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(jié)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(jié)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(jié)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(yuǎn))
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
