A．cutting downB．taking downC．pulling downD．breaking down

分析 一項新的研究表明，人們每天所采取的基本措施能夠對減少溫室氣體的排放大有幫助．

解答 答案：A
A．cutting down 削減，減少；  B．taking down 記下，拿下； C．pulling down拆毀，毀壞；D．breaking down 分解，發(fā)生故障；分析句意可知，與此處動詞短語搭配的賓語是greenhouse gas emissions"溫室氣體的排放"，以及根據(jù)句中basic steps taken by people daily"人們每天采取的基本措施"可推斷出，這里的A new study"一項新的研究"指的應是：人們每天采取的措施對減少溫室氣體排放量的影響；故選A

點評 本題考查了動詞短語cut down 的用法．做本題時，主要應根據(jù)句意以及與該動詞短語相搭配的賓語的提示，并結合各選項中動詞短語的意思，進行邏輯推理，然后找到符合該處句意的選項．本題的難點在于對各動詞短語意思的把握上，因此平時應注意增加詞匯及短語的積累，并需要牢固記憶．

2．Mark Twain has been called the inventor of the American novel．And he surely deserves additional praise：the man who popularized the clever literary attack on racism．
I say clever because anti-slavery fiction had been the important part of the literature in the years before the Civil War．H．B．Stowe's Uncle Tom's Cabin is only the most famous example．These early stories dealt directly with slavery．With minor exceptions，Twain planted his attacks on slavery and prejudice into tales that were on the surface about something else entirely．He drew his readers into the argument by drawing them into the story．
Again and again，in the postwar years，Twain seemed forced to deal with the challenge of race．Consider the most controversial，at least today，of Twain's novels，Adventures of Huckleberry Finn．Only a few books have been kicked off the shelves as often as Huckleberry Finn，Twain's most widely read tale．Once upon a time，people hated the book because it struckthemas rude．Twain himself wrote that those who banned the book considered the novel"trash and suitable only for the slums（貧民窟）．"More recently the book has been attacked because of the character Jim，the escaped slave，and many occurrences of the word nigger．（The term Nigger Jim，for which the novel is often severely criticized，never appears in it．）
But the attacks were and are silly-and miss the point．The novel is strongly anti-slavery．Jim's search through the slave states for the family from whom he has been forcibly parted is heroic．As J．Chadwick has pointed out，the character of Jim was a first in American fiction-a recognition that the slave had two personalities，"the voice of survival within a white slave culture and the voice of the individual：Jim，the father and the man．"
There is much more．Twain's mystery novel Pudd'nhead Wilson stood as a challenge to the racial beliefs of even many of the liberals of his day．Written at a time when the accepted wisdom held Negroes to be inferior （低等的） to whites，especially in intelligence，Twain's tale centered in part around two babies switched at birth．A slave gave birth to her master's baby and，for fear that the child should be sold South，switched him for the master's baby by his wife．The slave's light-skinned child was taken to be white and grew up with both the attitudes and the education of the slave-holding class．The master's wife's baby was taken for black and grew up with the attitudes and intonations of the slave．
The point was difficult to miss：nurture （養(yǎng)育），not nature，was the key to social status．The features of the black man that provided the stuff of prejudice-manner of speech，for example-were，to Twain，indicative of nothing other than the conditioning that slavery forced on its victims．
Twain's racial tone was not perfect．One is left uneasy，for example，by the lengthy passage in his autobiography （自傳） about how much he loved what were called"nigger shows"in his youth-mostly with white men performing in black-face-and his delight in getting his mother to laugh at them．Yet there is no reason to think Twain saw the shows as representing reality．His frequent attacks on slavery and prejudice suggest his keen awareness that they did not．
 Was Twain a racist？Asking the questioning the 21 stcentury is as wise as asking the same of Lincoln．If we read the words and attitudes of the past through the"wisdom"of the considered moral judgments of the present，we will find nothing but error．Lincoln，who believed the black man the inferior of the white，fought and won a war to free him．And Twain，raised in a slave state，briefly a soldier，and inventor of Jim，may have done more to anger the nation over racial injustice and awaken its collective conscience than any other novelist in the past century．

65．How do Twain's novels on slavery differ from Stowes？B
A．Twain was more willing to deal with racism．
B．Twain's attack on racism was much less open．
C．Twain's themes seemed to agree with plots．
D．Twain was openly concerned with racism．
66．Recent criticism of Adventures of Huckleberry Finn arose partly from itsD．
A．target readers at the bottom                                    
B．anti slavery attitude
C．rather impolite language                                                
D．frequent use of"nigger"
67．What best proves Twain's anti slavery stand according to the author？C
A．Jim's search for his family was described in detail．
B．The slave's voice was first heard in American novels．
C．Jim grew up into a man and a father in the white culture．
D．Twain suspected that the slaves were less intelligent．
68．The story of two babies switched mainly indicates thatC．
A．slaves were forced to give up their babies to their masters
B．slaves babies could pickup slave holders‵way of speaking
C．blacks‵social position was shaped by how they were brought up
D．blacks were born with certain features of prejudice
69．What does the under lined word"they"in Paragraph 7 refer toD？
A．The attacks．
B．Slavery and prejudice．
C．White men．
D．The shows．
70．What does the author mainly argue for？A
A．Twain had done more than his contemporary writers to attack racism．
B．Twain was an admirable figure comparable to Abraham Lincoln．
C．Twain's works had been banned on unreasonable grounds．
D．Twain s works should be read from a historical point of view．
