考研英語大綱中，明確規(guī)定考生要有能力做到：“根據(jù)上下文推斷重要生詞或詞組的含義”。針對這一要求，閱讀理解中會出一種專門的題型，即：猜詞題。以下是小編為大家整理的2017考研英語閱讀詞匯題解題技巧，僅供大家參考。

　　一、英語閱讀詞匯題必殺技之根據(jù)構(gòu)詞法推測

　　And the bank has done this even though its advisors say the dam will cause hardship for the powerless and environmental destruction. The benefits are for the powerful, but they are far from guaranteed.

　　52. In paragraph 5, “the powerless” probably refers to ________.

　　[A] areas short of electricity

　　[B] dams without power stations

　　[C] poor countries around India

　　[D] common people in the Narmada Dam area

　　題目要求推測“the powerless” 指的是什么，根據(jù)構(gòu)詞法，詞根power是權(quán)力，less是否定后綴，the加形容詞是表示一類人，所以“the powerless”是沒有權(quán)力的人。選項中只有D說到了common people普通人即沒有權(quán)力的人。C選項說的是貧困國家;A和B都是取得power的另一個含義：電力， short of electricity和without power都是在說沒電。由此可以看出，猜詞題切忌只看詞的表面含義，要對詞性有準確的判斷，然后結(jié)合上下文合理推斷。

　　二、英語閱讀詞匯題必殺技之根據(jù)下文解釋推測

　　As a result, the modern world is increasingly populated by intelligent gizmos whose presence we barely notice but whose universal existence has removed much human labor. Our factories hum to the rhythm of robot assembly arms.

　　47. The word “gizmos” (Line 1) most probably means ________.

　　[A] programs

　　[B] experts

　　[C] devices

　　[D] creatures

　　題目要求推測“gizmos”的含義，改詞沒有明顯構(gòu)詞特點，所以找上下文聯(lián)系。下文中是原因狀語從句對其解釋說明，whose presence we barely notice but whose universal existence has removed much human labor.“它廣泛存在，并能幫人類干活”，說明是一個工具類的東西。鎖定答案范圍[A] programs和[C] devices，再結(jié)合下文的列舉，robot assembly arms，automated teller terminals，robot-drivers，證明是一個機器設(shè)備，所以選擇C。很多猜詞都是要結(jié)合上下文內(nèi)容去推，找順向關(guān)系或反向關(guān)系，原因解釋屬于順向關(guān)系。

　　三、英語閱讀詞匯題必殺技之根據(jù)對應(yīng)結(jié)構(gòu)推測

　　It’s a theory to which many economists subscribe, but in practice it often leaves railroads in the position of determining which companies will flourish and which will fail. “Do we really want railroads to be the arbiters of who wins and who loses in the marketplace?”

　　34. The word “arbiters” most probably refers to those _______.

　　[A] who work as coordinators

　　[B] who function as judges

　　[C] who supervise transactions

　　[D] who determine the price

　　所推詞匯“arbiters”有后置定語，市場上誰贏誰輸?shù)?ldquo;arbiters”，句子是反問句，結(jié)合前文出現(xiàn)determining which companies will flourish and which will fail決定哪個公司會興盛哪個公司會失敗。該結(jié)構(gòu)與 the arbiters of who wins and who loses 形成對照關(guān)系，所以arbiters等于determining，意思是“決定”，答案為[B] who function as judges。
