  介詞、連詞是英語中使用的非常多的,那么我平時是怎么的用法呢,下面就是小編給大家?guī)淼闹锌加⒄Z語法專題詳解三:介詞、連詞,希望能幫助到大家!

  介詞、連詞

  一、介詞

  1. 介詞概述:介詞表示它與后面的名詞或代詞與其他句子成分的關(guān)系。介詞是虛詞,不能單獨(dú)做句子成分。介詞在英語中用法很活,也無一定規(guī)律可循。在初中范圍內(nèi)還應(yīng)學(xué)一個記住一個,特別是那些和動詞的特殊搭配。

  2. 常用介詞的意義和用法。

  ⑴ 時間或地點(diǎn)介詞in、on、at的用法區(qū)別:

  表示時間時, in表示在一段時間里(在將來時句子中則表示在一段時間之后), on表示在具體的某一天或者某天的上下午等, at表示在某個時刻或者瞬間;

  表示地點(diǎn)時, in表示在某個范圍之內(nèi), on表示在某個平面上或與一個面相接觸,at則表示在某個具體的場所或地點(diǎn)。如:

  He was born on the night of May 10th.

  I usually get up at 7:00 in the morning.

  His glasses are on the desk.

  My brother is at the bus stop.

 ?、?after與in表示時間的用法區(qū)別:“after+(具體時刻/從句)”表示“在…時刻之后”常用于一般過去時態(tài);“in+(一段時間)”表示“在(多久)之后”,常用于將來時態(tài)。如:

  He said that he would come back after 6:00.

  My father is coming back from Astralia in about a month.

 ?、?since與for表示時間的用法區(qū)別:“since+(具體時刻/that-從句)”表示“自從…起一直到現(xiàn)在”,“for +(一段時間)”表示“持續(xù)一段時間”,都常用于完成時態(tài);如:

  My father has worked in this factory since 1970.

  My father has worked in this factory for over 30 years.

  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”某個交通工具或“以……方式”,在被動句中可以表示動作的執(zhí)行者;in表示“使用”某種語言/文字,with表示“使用”某個具體的工具、手段。如:

  We write with our hands and walk with our feet.

  Please speak in English.

  Let’s go to the zoo by bus.

  It was invented by Adison.

  ⑸ about與on的用法區(qū)別:都可以表示“有關(guān)…”,但是about的意義比較廣,而on主要表示“有關(guān)…(專題/課程)”。如:

  Tom is going to give a speech on the history of China.

  They are talking about the English test.

 ?、?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…”時只能用over. 如:

  Just then a kangaroo (鼠)ran across the road.(就在那時一只袋鼠跑過路面)

  There is a bridge across/over the river.(河上有座橋)

  They climbed over the mountain and arrived there (他們翻過大山到達(dá)了那里)/

  The visitors went through a big gate into another park.(參觀者們穿過一個大門來到另一個公園)

  (7)as與like的區(qū)別:兩個詞都表示“像……”,但是as譯為“作為……”,表示的是職業(yè)、職務(wù)、作用等事實(shí),而like譯為“像……一樣”,表示外表,不是事實(shí)。如:

  Let me speak to you as a teacher.(我以老師的身份和你講話。)

  Let me speak to you like a teacher.(讓我像一位老師一樣和你講話)

  (8)in front of 與in the front of:in front of“在…的前面”, 與in the front of“在…的前部”。如:

  A group of people was standing in front of the hall.

  In the front of the hall stood a group of people.

  (12)except與besides的區(qū)別:except“除了”,表示排除掉某人物,即不包含;而besides“除了”則表示包含,即“不僅……又……”。如:

  Everyone went to the park except Tom.(除了Tom,大家都去了公園)(Tom沒有去公園)/

  Besides maths he also studied many other subjects.(除了數(shù)學(xué)之外,他還學(xué)其他許多功課)(“數(shù)學(xué)”也是他學(xué)的功課之一)

  連詞

  1.連詞概述:連詞是一種虛詞,用于連接單詞,短語或句子,但不單獨(dú)做句子成分。按照連詞的性質(zhì),可將連詞分為并列連詞和從屬連詞。并列連詞如:and,but,or,for等,它們即可連接單詞,短語,又可連接句子。從屬連詞如:when,before ,because等,它們主要引導(dǎo)名詞性從句。
