Hastings‘ contracture is a disorder of the connective tissue in one or both hands,most commonly causing loss of mobility.H痙攣是一只或者兩只手組織的連接錯位,經(jīng)常會導(dǎo)致活動不便.A survey of thousands of medical-insurance claims found that over 30 percent of people who had one hand operated on for Hastings'contracture underwent surgery a second time for this disorder within three years.一項研究了上千份的醫(yī)療保險索賠單的調(diào)查發(fā)現(xiàn),超過百分之三十的人有一只手進行過H痙攣的手術(shù),并且在三年內(nèi)進行過兩次.Clearly,therefore,a single surgical treatment of Hastings' contracture is often ineffective at providing long-term correction of the disorder很明顯的,因此,對于H痙攣,一次手術(shù)治療不能保證其長期的錯位糾正.
Which of the following,if true,most seriously weakens the argument?下列如果是真的,哪個最能削弱論點.
(A) The medical-insurance claims did not specie whether the surgery was on the patient's right or left hand.醫(yī)療保險索賠沒有明確出到底是病人的左手還是右手做過手術(shù).(B) The surgical techniques used to treat Hastings' contracture are identical to those used successfully to treat certain work-related injuries to the hand.(C) A separate survey found that 90 percent of patients operated on for Hastings' contracture report increased hand mobility within one month after the surgery.另一份研究發(fā)現(xiàn)90%的病人接受過H痙攣手術(shù)在手術(shù)后1個月內(nèi)手的痙攣有改善.(D) All of the patients in the survey were required by their insurance companies to seek a second opinion from a qualified surgeon before undergoing the operation.所有調(diào)查的病人,在進行手術(shù)前,保險公司都要求他們向優(yōu)秀的外科醫(yī)生詢問建議.(E) Many people who have Hastings' contracture choose to tolerate its effects rather than undergo the risks of surgery.
答案是A,CD為何不對呢?排除它因?
個人覺得,選A是因為有可能那百分之30的人都是雙手痙攣,所以第一次手術(shù)是左手,第二次是右手,再說以,結(jié)論就不能說,一次手術(shù)是不能長期有效的.
C項,1個月內(nèi)有改善,但是沒有說之后怎么樣,有可能三年內(nèi)還要繼續(xù)做手術(shù),所以不影響結(jié)論：一次手術(shù)不能長期有效.
D項,其實我覺得這完全不會影響結(jié)論啊~
可以交流一下啦,都是個人意見
真的是很難的題但是D我可以理解為病人是在手術(shù)前被保險公司要求組進行二次手術(shù)的，而并非是因為一次手術(shù)無效？D的意思是 All of the patients in the survey were required by their insurance companies to seek a second opinion from a qualified surgeon before undergoing the operation.調(diào)查里的那些病人，在進行手術(shù)前，保險公司都要求他們向優(yōu)秀的外科醫(yī)生詢問建議。怎么可以理解為保險公司要求他們做二次手術(shù)呢？a second opinion在這里是補充意見的意思，不能理解為二次手術(shù)~ 關(guān)鍵還是對D理解的問題吧，AC懂了嗎？
