七年級英語語法雖然是從簡單的壹些日常用語出發的，但語法中常會有壹些知識點看起來很細小，容易被忽視，但這些知識點掌握不熟練，往往會造成壹些語法應用上的錯誤。因此在學習七年級英語語法時，要認真、細心，不要覺得壹些地方不重要而得過且過。
下面從幾個方面，總結出了七年級英語語法，如果要復習英語句法的同學，可以參考壹下，
壹、七年級英語語法——詞法
1、名詞
A）、名詞的數
我們知道名詞可以分為可數名詞和不可數名詞，而不可數名詞它沒有復數形式，但可數名詞卻有單數和復數之分，復數的構成如下：
壹）在後面加s。如：fathers, books, Americans, Germans, apples, bananas
二）x, sh, ch, s, tch後加es。如：boxes, glasses, dresses, watches, wishes, faxes
三）1）以輔音字母加y結尾的變y為i再加es 如：baby-babies, family-families, duty-duties, comedy-comedies, documentary-documentaries, story-stories
2）以元音字母加y結尾的直接加s。如：day-days, boy-boys, toy-toys, key-keys, ways
四）以o結尾加s（外來詞）。如：radios, photos, 但如是輔音加o的加es：如: tomatoes西紅柿, potatoes馬鈴薯
五）以f或fe結尾的變f為v再加es(s)。如：knife-knives, wife-wives, half-halves, shelf-shelves, leaf-leaves, yourself-yourselves
六）單復數相同（不變的）有：fish, sheep, deer鹿子, Chinese, Japanese
七）壹般只有復數，沒有單數的有：people,pants, shorts, shoes, glasses, gloves, clothes, socks
八）單詞形式不變，既可以是單數也可以是復數的有：police警察局，警察, class班，同學, family家，家庭成員
九）合成的復數壹般只加主要名詞，多數為後壹個單詞。如：action movie-action movies, pen pal-pen pals; 但如果是由man或woman所組成的合成詞的復數則同時為復數。如：man doctor-men doctors, woman teacher-women teachers
十）有的單復數意思不同。如：fish魚 fishes魚的種類, paper紙 papers報紙，卷子，論文, work工作 works作品，工廠, glass玻璃 glasses玻璃杯，眼鏡, orange桔子水 oranges橙子, light光線 lights燈, people人 peoples民族, time時間 times時代, 次數, chicken 雞肉 chickens 小雞
十壹） 單個字母的復數可以有兩種形式直接加s或’s。如：Is (I’s), Ks (K’s)。但如是縮略詞則只加s。如：IDs, VCDs, SARs
十二） 特殊形式的有：child-children, man-men, woman-women, foot-feet, mouse-mice, policeman-policemen, Englishman-Englishmen
B）名詞的格
當我們要表示某人的什麽東西或人時，我們就要使用所有格形式。構成如下：
壹）單數在後面加’s。如：brother’s, Mike’s, teacher’s
二）復數以s結尾的直接在s後加’，如果不是以s結尾的與單數壹樣處理。如：Teachers’ Day教師節, classmates’; Children’s Day六壹節, Women’s Day三八節
三）由and並列的名詞所有時，如果是***同所有同壹人或物時，只加最後壹個’s，但分別擁有時卻分別按單數形式處理。如：Mike and Ben’s room邁克和本的房間（***住壹間），Mike’s and Ben’s rooms邁克和本的房間（各自的房間）
2、代詞

he him his his himself
it it its its this that itself

3、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：

二）以不發音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）以重讀閉音節結尾且壹個元音字母＋壹個輔音字母（註意除開字母組合如show –showing, draw-drawing）要雙寫最後的輔音字母再加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 位於
4、形容詞的級
我們在對兩個或以上的人或物進行對比時，則要使用比較或最高級形式。構成如下：
