上海新航道托福小編給大家?guī)砹送懈ｉ喿x題型重點(diǎn)關(guān)注之替換題，希望幫助考生對(duì)照文本更好的研究真題，充分備考，爭取理想成績，實(shí)現(xiàn)留學(xué)夢(mèng)想。

  句子替換題比較考察內(nèi)功，讀長句的能力。那么有沒有空子可以鉆呢?答案是有的。這類句子一般都很長，長句怎么構(gòu)成，需要很多從句填充，需要連詞連接兩個(gè)句子，需要有邏輯詞表達(dá)句意，我們的突破口，就放在邏輯詞上面。

  無恥技巧 1

  找到句子中的邏輯詞，然后對(duì)照選項(xiàng)，如果只有一個(gè)邏輯詞與之相符合，那么直接選，無需看答案。

  舉個(gè)例子：

  Although management was pleased withthe toughness that Truman hadshown and many citizens were pleased thatdisruption of the economy had been avoided, concern was expressed about theconstitutionality of having congress that such a step.

  A.Thoughsome were pleased that Truman had kept the economy going, there was concernabout how he had done it.

  B.Duringthe strike, the economy was disrupted, and congress was forced to take steps tofix it.

  C.Becauseof the effects of the strike on the citizens of the country, it wasnecessary for congress to make changes to the consititution.

  D.Management took tough actions during the strike; as a result, congressexpressed concern about the steps that management had taken.

  有的同學(xué)拿到了這個(gè)句子之后，開始惆悵，開始?jí)阂郑@么長，看著都煩了要怎么讀?其實(shí)你可以不讀，看見 although，往下看沒有邏輯詞了，去看選項(xiàng)吧，A選項(xiàng)though 也轉(zhuǎn)折;B選項(xiàng)沒有邏輯詞;C選項(xiàng)因果;D選項(xiàng)因果。所以直接選 A。

  無恥技巧 1小貼士：

  對(duì)于這個(gè)技巧有一個(gè)補(bǔ)充，就是對(duì)于因果邏輯關(guān)系，選項(xiàng)中往往會(huì)設(shè)置幾個(gè)因果邏輯的句子，這時(shí)我們要區(qū)分哪一部分是因，哪一部 分是果，通常會(huì)有把因果調(diào)過來的迷惑選項(xiàng)。

  看例題：

  Duringthat period of time, because of the huge glaciers, sea levels were asmuch as 100 meters lower than they are today.

  A.sincethe Ice Age, the amount of water in the oceans has decreased dramatically

  B.Duringthe Ice Age, sea levels were low because of how much water was frozen.

  C.Glaciers have growntremedously since the last Ice Age.

  D.Duringthe Ice Age, huge glaciers displaced a lot of water, causing the oceans torise.

  第一步，找邏輯詞，because of，因果邏輯。

  有同學(xué)一看選項(xiàng)，選 A，since!錯(cuò)!since在這里根本不是因?yàn)榈囊馑迹亲詮摹Ｎ覀儊碇鹨豢聪逻x項(xiàng)：

  A.沒有邏輯詞;

  B.有因果，保留;

  C.無邏輯詞;

  D.causing有因果。

  這樣是剩下B，D，現(xiàn)在開始使用小貼士，看原句，huge glaciers是因，BD都正 確，sea levels下降了，是果，D的結(jié)果是 rise，與原文相反，排除掉，選擇 B。

  以上所寫，是這類題中較簡單的類型，難題的思路和方法是一致的， 只是有兩三個(gè)邏輯，相當(dāng)于簡單類型的堆砌。這個(gè)時(shí)候我要注意區(qū)分主邏輯和次要邏輯。在條件句中，結(jié)果是重要的，條件不重要!

  無恥技巧 2

  關(guān)于 however的處理，當(dāng) however出現(xiàn)在主語，謂語之間或謂語賓語之間時(shí)， 把 however提到句首，翻譯成但是，在本句中無地位不表示邏輯，對(duì)本句無任何影響，而表示本句話與上句話之間是轉(zhuǎn)折關(guān)系。

  總結(jié)一下句子替換題：首先挑出句子的邏輯詞，確定主邏輯，對(duì)照選項(xiàng)排除，然 后看是否改換了句子的主干。
