12．How do you spend your time？To get it，Paul T．Rankin asked sixty-eight individuals to keep an accurate，detailed record of what they did every minute of their waking hours．He discovered that 70percent of their waking time was spent on one thing only-communication．Put that evidence alongside the research findings uncovered by the Human Engineering Laboratories，they discovered that，vocabulary，more than any other factor yet known，predicts financial success．New words make us better thinkers as well as communicators．What better reason for beginning right now to extend your vocabulary？But how？
Hybrid （雜交產(chǎn)生的） corn combines the best qualities of several varieties to ensure maximum productivity．A hybrid approach to vocabulary should，in the same way，ensure maximum results．That's why you should use the CPD formula．
Through Context．When students in a college class were asked what should be done when they came across an unknown word in their reading，84percent said，"Look it up in the dictionary．"If you do，however，you short-circuit the very mental processes needed to make your efforts most productive．
But there's another reason．Suppose someone asks you what the word"fast"means．You answer，"speedy or swift"．But does it mean that in such context as"fast color"or"fast friend"？And if a horse is fast，is it securely tied or galloping at top speed？It could be either．It all depends．On the dictionary？No，on the context．After all，there are over twenty different meanings for"fast"in the dictionary．But the dictionary doesn't tell you which meaning is intended．That's why it makes such good sense to begin with context．
Through Word Parts．Now for the next step．Often unfamiliar words contain one or more parts，which，if recognized，provide definite help with meaning．Take the word"monolithic"for example．Try to separate the parts．There is the prefix mono-，meaning"one"，and the root-lith，meaning"stone"．Finally，there's the suffix-ic，meaning"consisting of"．Those three parts add up to this definition："consisting of one stone"．
To speed up your use of word parts，you will be introduced to the fourteen most important words in the English language．The prefix and root elements in those few words are found in over 14，000words．With those amazingly useful shortcuts，you can build up vocabulary，not at a snail's pace，one word at a time，but in giant leaps，up to a thousand words at a time．
Through the Dictionary．Now you can see why you should consult the dictionary last，not first．You've looked carefully at the context．You've looked for familiar word parts．Now you play Sherlock Homes．In light of context or word parts，you try to solve a mystery．What exactly does that strange word mean？Only after you go through the mental gymnastics to come up with a tentative （不確定的） definition should you open the dictionary to see if you're right．
You are now personally involved．Your increased interest will lead to a better memory of both word and meaning．It also encourages your development of the habits needed to accelerate your progress．And when you see in black and white the definition you had expected，what a feeling of accomplishment is yours．In that way，the CPD Formula provides the exact approaches for maximum effectiveness．
Well，there it is，your new formula-Context，Parts，Dictionary．Use it!The results will be like the money in the bank．

分析 本文屬于說明文閱讀，作者通過這篇文章主要向我們描述了通過CPD公式擴(kuò)大詞匯量的幾種方法：分析詞匯的組成部分，增加詞匯部分的使用，通過字典查閱詞匯的意義和用法，真心喜歡和使用詞匯．
解答 46．B．細(xì)節(jié)理解題．根據(jù)文章第一段"they discovered that，vocabulary，more than any other factor yet known，predicts financial success"可知類工程實(shí)驗(yàn)室的研究結(jié)果表明收入與詞匯密切相關(guān)；故選B．
47．D．細(xì)節(jié)理解題．根據(jù)文章第二段"When students in a college class were asked what should be done when they came across an unknown word in their reading，84percent said，"Look it up in the dictionary"當(dāng)遇到一個(gè)不熟悉的單詞時(shí)，大多數(shù)大學(xué)生會(huì)查閱字典，故選D．
48．A．詞義推斷題．根據(jù)文章第五段"Those three parts add up to this definition："consisting of one stone""這三個(gè)部分總計(jì)達(dá)這樣的定義：由一種石頭組成，故可推測(cè)monolingual是只涉及一種語言的意思；故選A．
49．D．主旨大意題．通讀全文，根據(jù)文章最后一段"there it is，your new formula-Context，Parts，Dictionary"可知文章主要在教育讀者通過CPD公式擴(kuò)大詞匯量；故選D．
點(diǎn)評(píng) 考察學(xué)生的細(xì)節(jié)理解和推理判斷能力，做細(xì)節(jié)理解題時(shí)一定要找到文章中的原句，和題干進(jìn)行比較，再做出正確的選擇．在做推理判斷題不要以個(gè)人的主觀想象代替文章的事實(shí)，要根據(jù)文章事實(shí)進(jìn)行合乎邏輯的推理判斷．
