Question

17．Do you have a good memory？Maybe you remember better than all of your friends．But even if you have a short-term memory，it's better than a chimpanzee's（黑猩猩），right？Well，you may be wrong．
    Tetsuro Matszawa，a scientist from Kyoto University，Japan has showed how chimps have far better memories than humans．"We learn that chimps have great memories by doing tests，"he told The Guardian"You can do things to improve your memory．"
    How do chimps have better memories than us？Scientists t ested four chimps and human volunteers．They showed them five numbers on a computer screen．Chimps and human volunteers had to remember the numbers correctly．But to make it hard，the numbers dis appeared after seven tenths of a second．Then they will reduce the time to two tenths of a second．While humans began to make mistak e after mistake，the young chimps still did very well．
    Why do they have better memories？We share 98.8 percent of our DNA with chimps．But during evolution（進化），we lost some of our shared abilities．As humans learned new skills，like language，we had to lose some of our memory skills to make room in our brains．"To get something，we had to lose something，"said the scientist．
    Chimps need good memories to survive．When a chimp looks up at the big tree and pick a banana，he must remember where he saw it as he fights off competition from other animals．
33．What did the scientist's study find？B
A．Chimps can remember all of their friends．
B．Chimps have better memories than humans．
C．Chimps do things to improve their memories．
D．Chimps can do many things better than humans．
34．Which of the followi ng is TRUE of the test？D
A．Five chimps and human volunteers were tested．
B．The numbers first disappeared after a second．
C．Humans made fewer mistakes than chimps．
D．The chimps did a better job than humans．
35．During evolution，humansC．
A．lost 98.8 percent of their DNA shared with chimps
B．needed very good memories to survive
C．gained skills but also lost skills
D．learned to compete against chimps．

Answer 1

分析 文章介紹了一個實驗，研究人員通過實驗表明了黑猩猩在記憶方面比人類要強．

解答 B D C
33．B 推理題．根據(jù)第二段Japan has showed how chimps have far better memories than humans．"We learn that chimps have great memories by doing tests得知，研究人員的目的是測試黑猩猩的記憶比人類要強，故選B．
34．D 細(xì)節(jié)題．Scientists t ested four chimps and human volunteers暗示A錯誤；the numbers dis appeared after seven tenths of a second得出B錯；While humans began to make mistak e after mistake，the young chimps still did very well．推出C錯誤；并且得出選項D正確，即黑猩猩在測試中表現(xiàn)比人類要更好．
35．C 細(xì)節(jié)題．在文章中To get something，we had to lose something可知，人類獲得某個技能的同時又失去了其他技能，故選C．

點評 考察學(xué)生的細(xì)節(jié)理解和推理判斷能力，做細(xì)節(jié)理解題時一定要找到文章中的原句，和題干進行比較，再做出正確的選擇．在做推理判斷題不要以個人的主觀想象代替文章的事實，要根據(jù)文章事實進行合乎邏輯的推理判斷
