高考英語單元知識(shí)點(diǎn)復(fù)習(xí)Unit 18
提示:本題考查狀語從句引導(dǎo)詞的用法。the moment作為連詞使用，引導(dǎo)狀語從句，相當(dāng)于as soon as；until表示“直到”，在此不合情理；while作“在……時(shí)”講時(shí)，后面不跟短暫動(dòng)詞；by the time的主句中常用將來完成時(shí)或過去完成時(shí)。
答案:d
2. ...immediately when...
講:注意觀察下面教材原句:
david’s career took off almost immediately when he was part of the manchester united’s youth team that won the fa youth cup in 1992.
(差不多)就在大衛(wèi)作為曼聯(lián)青年隊(duì)的成員于1992年贏得英國足球總會(huì)青年杯后，他的事業(yè)開始起色。
在時(shí)間狀語從句的引導(dǎo)詞前可以加上副詞進(jìn)行修飾，表示更加具體的時(shí)間。例如:soon after.../shortly after.../not long before.../long before 等。
例:he came home immediately after he finished his work.
他做完工作后馬上就回家了。
she got married soon after she graduated from the college.
她大學(xué)畢業(yè)后不久就結(jié)婚了。
i had known him long before he came to work in my office.
在他來我辦公室工作之前很久我就認(rèn)識(shí)他。
練:come in ________you have taken off your coat,it’s too cold outside.
a.long before b.immediately when
c.soon after d.long after
提示:從后半句話所提供的語境分析，此處用immediately when表時(shí)間非常短暫，其他項(xiàng)和語境不符。
答案:b
辨析
1.across,through
across表示“橫過、橫穿、越過”時(shí)，它的含義與on,over有關(guān)，側(cè)重于動(dòng)作在某一物體或某一地方的表面進(jìn)行。作介詞時(shí)，across還可表示“在……的對(duì)過”；作副詞時(shí)，表示“對(duì)過”和“橫過”。
through表示“通過、穿過”時(shí)，它的含義與in有關(guān)，側(cè)重動(dòng)作在某一物體空間里進(jìn)行，含有“從中間通過”之意。
即時(shí)練習(xí):
(1)look around when you walk________ the street.
(2)we drove straight________ the town.
(3)she swam________ the river.
(4)waste water flows ________this pipe to a treatment plant.
(5)the lake was frozen so we walked________ the ice.
答案:(1)across (2)through (3)across (4)through (5)across
2.be famous for,be famous as
be famous for后的介詞賓語是主語的所述內(nèi)容；be famous as后的介詞賓語與主語是同位成分。
人+be famous for表示“因某種知識(shí)、技能或特征而出名”。人+be famous as表示“因某種身份而出名”。
地名+be famous for表示“以某種特產(chǎn)而出名”。地名+be famous as表示“以什么樣的產(chǎn)地或地方而出名”。
sth.+be famous for表示“以其內(nèi)容、特征、價(jià)值等被人所知”。sth.+be famous as表示“以某種形式而出名”。
