高一英語(yǔ):必修一Unit2單元知識(shí)點(diǎn)梳理

2017-02-17 21:51:45 來(lái)源:精品學(xué)習(xí)網(wǎng)

   核心單詞

  1. command

  n. & vt. 命令;指令;掌握

  The officer commanded his soldiers to fire.

  那名軍官命令士兵們開(kāi)火。

  A general is a man who commands a large number of soldiers.

  將軍是統(tǒng)率眾多士兵的人。

  常用結(jié)構(gòu):

  at/ by sb’s command 聽(tīng)某人支配

  take command of 控制

  in command of 指揮著

  under one’s command 由某人的指揮

  under the command of sb. 在某人的指揮下

  command sb. to do sth. 命令某人做某事

  command (=order) that ... 命令……(從句用虛擬語(yǔ)氣,即should+ do 形式,should可省略)

  聯(lián)想拓展

  commander n. 指揮官

  高手過(guò)招

  用適當(dāng)?shù)慕樵~填空(原創(chuàng))

 、貴or the first time in years, she felt she was command

  of her life.

 、赥he army is the king’s direct command.

 、跿he police arrived and took command the situation.

 、賗n ②under/at/by ③of

  2. request

  vt.&n. 請(qǐng)求;懇求;要求

  常用結(jié)構(gòu):

  request sb. to do sth.請(qǐng)求某人做某事

  request sth. from/of sb. 向某人要求某物

  request that sb. (should) do sth.要求某人做某事

  make a request/requests 發(fā)出請(qǐng)求

  at the request of sb.=at sb.’s request依照某人的請(qǐng)求

  易混辨析

  request/demand/require

  request表示“有禮貌的請(qǐng)求;正式的請(qǐng)求”。

  demand表示“有正當(dāng)權(quán)利的要求”,因此含有“堅(jiān)決或強(qiáng)烈要求”的意思。

  require表示“要求所必須的東西;法律、協(xié)定、規(guī)章以及其他客觀情況的要求”。

  但它們也有不同之處:

 、賠equire和request都可以接賓語(yǔ)+to do sth.結(jié)構(gòu),而demand沒(méi)有此種用法。但可以說(shuō)demand of sb. to do sth.

 、趓equire+動(dòng)名詞時(shí),主動(dòng)形式的動(dòng)名詞具有被動(dòng)意義,而demand,request無(wú)此種用法。

  They are demanding higher wages. 他們要求提高工資。

  Do you require anything else? 你還要求(需要)別的嗎?

  Many people have requested this next song.

  許多人要求聽(tīng)下面這首歌。

  They required me to keep silent. 他們要求我保持沉默。

  The letter requested us to leave the house within six weeks.

  這封信要求我們六周內(nèi)搬出這所房子。

  溫馨提示

  以上三個(gè)詞的共同點(diǎn)是:從語(yǔ)法上看,request和demand,require都可以接that引導(dǎo)的賓語(yǔ)從句,并且在從句中要使用虛擬語(yǔ)氣。

  高手過(guò)招

  單項(xiàng)填空

  ①One of the requirements for a fire is that the material to its burning temperature.

  A. be heated B. is heated

  C. would be heated D. do heat

  ②—Why were you late for such an important concert?

  —The plane arrived at the airport after a of three hours. (2010·陜西商洛一輪檢測(cè))

  A. delay B. rest C. tour D. request

 、俳馕觯哼xA。如同require, demand, order, suggest, advise, insist, request等動(dòng)詞要求其后面的賓語(yǔ)從句使用虛擬語(yǔ)氣一樣,它們所對(duì)應(yīng)的名詞的同位語(yǔ)從句和表語(yǔ)從句也要求使用虛擬語(yǔ)氣,即:should+動(dòng)詞原形。故選A。

  ②解析:選A。上句詢問(wèn)“遲到的原因”,因此下句中的名詞應(yīng)是與“遲到”意義有關(guān)的名詞,所以只能選擇“延誤”。

  3. recognize

  vt. 辨認(rèn)出;承認(rèn);公認(rèn)

  常用結(jié)構(gòu):

  recognize sb. 認(rèn)出某人

  recognize one’s voice聽(tīng)出某人的聲音

  recognize ... as ... 認(rèn)定;承認(rèn)……為……

  recognize sb./sth. ... to be ...認(rèn)為某人/某事物是……

  recognize that ...承認(rèn)……

  When he walked out of the station, I recognized him immediately.

  當(dāng)他從車站里走出來(lái)時(shí),我立刻認(rèn)出了他。

  Everyone recognized him to be the lawful heir/as the lawful heir. 大家都承認(rèn)他為合法繼承人。

  高手過(guò)招

  單項(xiàng)填空

  —Oh, it’s you! I you.

  —I have just had my hair cut, and I’m wearing new glasses.

  A. hadn’t recognized B. haven’t recognized

  C. didn’t recognize D. don’t recognize

  解析:選C。前句的句意為:哦,是你呀!我剛才沒(méi)有認(rèn)出你來(lái)。

  所以要用一般過(guò)去時(shí)。

  4. direction

  n. [C] 方向;方面;[U]指導(dǎo);指揮
