1、第4講　詞義猜測(cè)類 題型概述 題型破解 1 語(yǔ)境分析猜詞義 解題指導(dǎo)　詞義猜測(cè)常用的五種方法：1.基本構(gòu)詞法：根據(jù)前后綴、合成及詞性轉(zhuǎn)換去猜測(cè)詞義；2.同義或定義解釋法：上下文中以某種方式對(duì)其進(jìn)行解釋，如利用or, that is (to say), in other words, namely等詞語(yǔ)進(jìn)行解釋，或利用破折號(hào)、同位語(yǔ)(從句)、定語(yǔ)從句等進(jìn)行解釋；3.前后對(duì)比法：上下文中往往對(duì)生詞提供一定的對(duì)比背景，且常以反義或?qū)φ盏姆绞匠霈F(xiàn)，以此可推測(cè)出生詞的含義；4.因果推斷法：結(jié)合上下文的因果關(guān)系進(jìn)行猜測(cè)；5.語(yǔ)境理解法：要準(zhǔn)確猜測(cè)出生詞的含義大多需要根據(jù)上下文語(yǔ)境去分析和推斷

2、。 [典例]　(2019·全國(guó)卷Ⅰ·B篇) ... But he's nervous. “I'm here to tell you today why you should ... should ...” Chris trips on the “－ld”， a pronunciation difficulty for many non－native English speakers.

3、e stumbles,_Chris is doing amazingly well. When he brings his speech to a nice conclusion, Whaley invites the rest of the class to praise him. ... 25．What does the underlined word “stumbles” in paragraph 2 refer to? A．Improper pauses. B．Bad manners. C．Spelling mistakes. D．Silly jokes. 解析　

4、A　根據(jù)第二段中的“you should ... should ...”以及“... Vote for ... me ...”這樣的語(yǔ)句特點(diǎn)可知，Chris的演講不流暢，也就是說(shuō)有不適當(dāng)?shù)耐ｎD。這是他表現(xiàn)不好的地方，與畫線詞后的句意“他完成得非常好”構(gòu)成轉(zhuǎn)折關(guān)系，與短語(yǔ)except for的語(yǔ)意相呼應(yīng)。故選A。 2 就近原則猜指代 解題指導(dǎo)　猜測(cè)代替詞的指代內(nèi)容，要求考生判斷代詞(it, one, they, this, that, these, those, which等)或助動(dòng)詞(do, does, did等)具體替代什么?？砂匆韵氯竭M(jìn)行：返回原文，找到指代詞→向上(有時(shí)向下)搜索

5、，找最近的名詞、代詞、短語(yǔ)或句子→將找到的詞、詞組或句子代入替代該指代詞，看意思和邏輯關(guān)系是否通順，從而確定最佳選項(xiàng)。 [典例]　 (2017·全國(guó)卷Ⅰ·C篇) ...

A．Jazz becoming more accessible. B．The production of jazz growing faster

7、. C．Jazz being less popular with the young. D．The jazz audience becoming larger. 解析　C　根據(jù)上一段中的“the jazz audience continues to shrink and grow older, and the music has failed to connect with younger generations”可知，爵士樂(lè)不怎么受現(xiàn)在年輕人的喜愛(ài)，所以that指代上文提到的這種狀況，故選C項(xiàng)。 3 意義吻合猜句意 解題指導(dǎo)　句意猜測(cè)要求考生通過(guò)閱讀文章，用合適的語(yǔ)句對(duì)其進(jìn)行解釋

8、性的描述。考生要注意以下兩點(diǎn)： 1.返回原文，找到該句，對(duì)原句進(jìn)行語(yǔ)法和邏輯關(guān)系分析。對(duì)于需要猜測(cè)句意的情形，首先要理解句子的前后特定語(yǔ)境，然后根據(jù)語(yǔ)境對(duì)此句在文中的意思進(jìn)行有依據(jù)的推理，最后再進(jìn)行歸納總結(jié)，得出答案；2.一般來(lái)說(shuō)，正確選項(xiàng)的意思和原句的意思完全相同，只不過(guò)是用其他的詞匯或句式來(lái)進(jìn)行了轉(zhuǎn)換表達(dá)而已。 [典例]　(2019·全國(guó)卷Ⅱ·B篇) “You can use me as a last resort (選擇), and if nobody else volunteers, then I will do it.” This was an actual reply fro

11、ncourage teamwork. B．Appeal to feelings. C．Promote good deeds. D．Provide advice. 解析　B　根據(jù)畫線短語(yǔ)前一句可知，這位家長(zhǎng)可能需要一點(diǎn)點(diǎn)勸說(shuō)。隨后作者對(duì)這位家長(zhǎng)進(jìn)行了舉例勸說(shuō)：一位有四個(gè)孩子的單親母親在主持這次活動(dòng)，一位孩子不在此隊(duì)的父親擔(dān)任長(zhǎng)曲棍球隊(duì)的教練。這些例子都是為了動(dòng)之以情，吸引這位家長(zhǎng)來(lái)做志愿工作，故答案為B。 過(guò)關(guān)檢測(cè)(限時(shí)：35分鐘) (2019·人民附中高三月考)Best friends may be priceless but the cost of keeping the r

19、友付出更多，他們會(huì)花168英鎊來(lái)為朋友買令人振作的物品，助其度過(guò)諸如關(guān)系破裂等困難時(shí)期。由此推斷畫線部分的意思應(yīng)該是“慷慨的”，故選B。 2．To keep the relationship, where do BFFs spend most money? A．Buying birthday presents. B．Cheering up a friend in low spirits. C．Paying for holiday gifts and other treats. D．Going a particular distance to visit friends.

20、答案：D　細(xì)節(jié)理解題。根據(jù)第二段中的“blowing ￡4,679 on birthday presents”“spend ￡168 on pick－me－ups (提神物品)”以及第三段中的“￡242 spent on presents ... from gifts bought on holiday to treats ...”“spend a whopping (巨大的) ￡18,000 on travel to see each other”可知，為了維持一段友誼，花在旅途中的費(fèi)用是最多的，所以選D。 3．What is Natasha's understanding of BFF

How can they stay off the dinner menu? One type of crab,

58、 known as the decorator crab, has found a clever solution. It “decorates” itself. Decorator crabs use seaweed or sea sponges to protect themselves from natural enemies. More than 100 types of decorator crabs are found worldwide. One type, commonly called the longnose spider crab, takes decorating to

Picking the right decorating material is important to the longnose spider crabs' chances of survival. “If the crabs just decorated themselves to look like the background, t

But by carefully choosing the peppery seaweed, these decorator crabs can make their natural enemies stay away from them. Once a longnose spider crab has put together a good suit of “seaweed armo
