2023年初中英語語法：介詞的用法歸納總結(jié)

1、介詞的主要用法：

介詞是一種虛詞,不能獨(dú)立使用。介詞之后一般有名詞或代詞(賓格)或相當(dāng)于名詞的其他詞類、短語或從句作它的賓語,即構(gòu)成介詞短語。有些介詞是由兩個(gè)以上的詞構(gòu)成的短語介詞,如：out of(從…中出來), because of(因?yàn)?, away from(距離…), on top of(在…頂上), ever since(自從…), next to(在…隔壁), according to(根據(jù)…), in front of(在…前方)等。

2、介詞的分類表：

3、介詞短語的句法作用：

介詞短語相當(dāng)于一個(gè)形容詞或副詞,可用作狀語、定語和表語。如：The man came.(狀)(那個(gè)人走下樓來)/The womanis from the countryside.(定)(頭上戴花的婦女來自鄉(xiāng)下)/The teacher is now with the pupils.(表)(老師現(xiàn)在和學(xué)生在一起)

4、介詞短語在句子中的位置：

介詞短語做狀語時(shí),如果表示時(shí)間/地點(diǎn),可以放在句首或句尾,如果表示方向/方式/伴隨/涉及/原因/目的/比較,一般放在句尾; 介詞短語作表語時(shí)放在連系動(dòng)詞之后;介詞短語作定語時(shí),只能放在被修飾的名詞之后。如：He wanted to find a good job in Shanghai the next year.(狀語)(他想來年在上海找份好工作)/ They searched the room for the thief.(他們?cè)诜块g里搜索小偷) / The letters are for you.(表語)(信是給你的)/ Have you seen a cat with a black head and four white legs?(定語)(你看見一只黑頭白腿的貓了嗎?)

5、重要注釋：

⑴ this / that / these / those / last / next / a / every / each等詞構(gòu)成的時(shí)間短語,前面不用任何介詞。如：Every year travellers from abroad come to visit Pingyao.(每年都有國外的游客來游覽平窯鎮(zhèn))/ He had a bad cold that week.(那個(gè)星期他患重感冒)

⑵ for有時(shí)用來引出動(dòng)詞不定式的邏輯主語,常翻譯成“對(duì)于…而言”。如：It’s too hard for me to finish the work in only one hour.(讓我在區(qū)區(qū)一個(gè)小時(shí)內(nèi)完成這項(xiàng)工作太難了)/ The house is big enough for 10 men to live in.(房子夠大的可以容10個(gè)人住)

⑶ of有時(shí)用來表示后面的人物正好是前面的表語的邏輯主語。如：It’s very nice/kind of you to do so.(你這么做真是太好了)

⑷ 介詞有時(shí)會(huì)與它的賓語分離,而且賓語前置。

① 當(dāng)賓語是疑問詞時(shí)。Who are you talking about?(你們?cè)谡務(wù)撜l?)

② 賓語在從句中當(dāng)連接詞時(shí)。He has a younger brother who he must take good care of.(他有 一個(gè)需要他照顧的小弟。) / Do you know who our teacher is talking with over there?(你知道我們的老師在那邊和什么人談話嗎?)

③ 動(dòng)詞不定式作定語且該動(dòng)詞為不及物動(dòng)詞,后面有介詞。I finally found a chair to sit on.(我 最終找到了一張椅子坐。)

(5) 記住一些固定詞組：arrive at/in(到達(dá)…),on foot(步行),not…at all(根本不),to the north of(在…以北),in the east of(在…的東部),in the night(在夜間),at night(在晚上),be afraid of(害怕…),be full of(充滿/ 裝滿….),be filled with(充滿/ 裝滿….),be good/bad for(對(duì)…有益/有害),be made of(由…做成),be made from(由…制造),play with(玩耍……),look out of(朝…外面看),at the end of(在…末梢/結(jié)束時(shí)),by the end of(不遲于…/到…末為止),with the help of或with one’s help(在…的幫助下),look after(照料…),look for(尋找…),on a bike(=by bike)騎車, help sb. with(幫某人做…),get on (well) with(與某人相處[融洽]),等等。

⑴ 時(shí)間或地點(diǎn)介詞in、on、at的用法區(qū)別：表示時(shí)間時(shí), in表示在一段時(shí)間里(在將來時(shí)句子中則表示在一段時(shí)間之后), on表示在具體的某一天或者某天的上下午等, at表示在某個(gè)時(shí)刻或者瞬間; 表示地點(diǎn)時(shí), in表示在某個(gè)范圍之內(nèi), on表示在某個(gè)平面上或與一個(gè)面相接觸,at則表示在某個(gè)具體的場(chǎng)所或地點(diǎn)。如：He was born on the morning of May 10th.(他出生于五月十日的早晨)/ I usually get up at 7：00 in the morning.(我通常在早上的七點(diǎn)鐘起床) / His glasses are right on his nose.(他的眼鏡就架在他的鼻子上)/ He is at the cinema at the moment.(此刻他正在電影院)

⑷ by、in與with表示方式的用法區(qū)別：都可以表示“工具、手段”,但是by主要表示“乘坐”某個(gè)交通工具或“以……方式”,在被動(dòng)句中可以表示動(dòng)作的執(zhí)行者;in表示“使用”某種語言/文字,with表示“使用”某個(gè)具體的工具、手段。如：We see with our eyes and walk with our feet.(我們用眼睛看東西,用雙腳走路)/ Please write that article(文章) in English.(請(qǐng)你用英語寫那篇文章)/ Let’s go to the zoo by taxi.(我們打的去動(dòng)物園吧。)/ It was written by Lao She.(那是老舍寫的)

⑹ through與across、over的用法區(qū)別： through指“穿過…(門洞/人群/樹林)”; across和over可以指“跨越…(街道/河流)”,可互換,但是表示“翻過…”時(shí)只能用over. 如：Just then a rat (鼠)ran across the road.(就在那時(shí)一只老鼠跑過路面)/ There is a bridge across/over the river.(河上有座橋)/ They climbed over the mountain and arrived there ahead of time.(他們翻過大山提前到達(dá)了那里)/ The visitors went through a big gate into another park.(參觀者們穿過一個(gè)大門來到另一個(gè)公園)
