单选题 When a rare disease ALD threatened to kill the four-year-old boy Lorenzo, his parents refused to give up hope. Doctors explained that there was no cure for ALD, and that he would probably die within three years. But Lorenzo's parents set out to prove the doctors wrong.
The parents devoted themselves to keeping their son alive and searching for a cure. But doctors and the families of other ALD patients often refused to take them seriously. They thought the efforts to find a cure were a waste of time, and drug companies weren't interested in supporting research into such a rare disease.
However, the parents still refused to give up and spent every available hour in medical libraries and talking to anyone who would help. Through trial and error (反复实验), they finally created a cure from ingredients (调料) commonly found in the kitchen. The cure, named" Lorenzo's Oil", saved the boy's life. Despite the good results, scientists and doctors remained unconvinced. They said there was no real evidence that the oil worked and that the treatment was just a theory. As a result, some families with ALD children were reluctant to try it.
Finally, the boy's father organized an international study to test the oil. After ten years of trials, the answer is: the oil keeps ALD children healthy.

单选题 Doctors said that Lorenzo might die within three years because ________.
A. they had never treated the disease before B. Lorenzo was too young to be, cured
C. no cure had been found for ALD D. ALD was a rare disease

【正确答案】 C

【答案解析】事实细节题。文章首段第二句Doctors explained that there was no cure for ALD，and that he would probably die within three years．(医生解释说当前还没有治疗ALD的药，因此他很可能在3年内死亡。)因此选C)。
[避错指导] A)“医生们以前没有治疗过这种疾病”、B)“洛伦佐还太小，所以无法接受治疗”、D)“ALD是一种罕见的疾病”均不是医生们判定洛伦佐只能活3年的根本依据。

单选题 The families of other ALD patients thought that ________.
A. the research for the new cure would cost too much money
B. the efforts of Lorenzo's parents were a waste of time
C. Lorenzo's parents would succeed in finding a cure
D. Lorenzo's oil was a real cure for ALD

【正确答案】 B

【答案解析】事实细节题。文章第二段末句说They thought the efforts to find a cure were a waste of time…(他们认为寻找治疗ALD的方法只是在浪费时间…)因此选B)。
[避错指导] A)“新方法的研制将耗资巨大”，文章没有提及；C)“洛伦佐的父母最终会找到治疗的方法”，并非其他ALD患者家属的看法；因为当时Lorenzo's oil 还未被发现，所以说它“是一种真正能治疗ALD的药物”还为时过早，故排除D)。

单选题 Scientists and doctors believed that Lorenzo's Oil ________.
A. was really effective B. was a success story
C. only worked in theory D. would save the boy's life

【正确答案】 C

【答案解析】事实细节题。文章第三段倒数第二句说They said there was no real evidence that the oil worked and that the treatment was just a theory．(他们说没有确凿的证据证明Lorenzo's oil 对这种疾病有疗效，这仅是理论上的治疗方法。)因此选C)。
[避错指导] A)“很有效果”、B)“是一个成功的案例”、D)“将会挽救男孩的生命”与文意不符，均非科学家和医生们的观点。

单选题 Lorenzo's father organized an international study to ________.
A. test Lorenzo's Oil B. get financial support
C. find a cure for the disease D. introduce the cure worldwide

【正确答案】 A

【答案解析】事实细节题。文章末段首句说the boy's father organized an international study to test the oil ．(孩子的父亲组织了一个科研小组来检测这种药的疗效。)这种药即指Lorenzo's oil，因此选A)。
[避错指导] B)“获得资金上的支持”、C)“找治疗疾病的方法”、D)“把这种药物推广到全世界”文中均未提及。

单选题 From the passage we can conclude that ________
A. doctors remain doubtful of the effectiveness of the cure
B. many ALD patients still refuse to use the oil
C. various cures have been found for ALD
D. the oil really works as a cure for ALD

【正确答案】 D

【答案解析】事实细节题。文章末句说After ten years of trials，the answer is the oil keeps ALD children healthy.(长达10年的试验最终证明：这种药物能使ALD病患儿童恢复健康。)可见这种药物对ALD具有治愈效果。
[避错指导] A)“医生们仍旧对该药物的效果持怀疑态度”只是片面观点，不是最终结论；文中第三段未句所说的reluctant意为“不情愿”，并非“拒绝”，因此排除B)“很多患者拒绝使用这种药物”；C)“各种ALD的治疗方法均已找到”文中没有提及。
