After a promising drug was found the final, most expensive stages of clinical trials, which measure the efficacy of a drug that has already been shown to be safe, could be publicly funded, using another portion of the huge potential savings from cheaper drugs, and conducted by independent laboratories. Once a medicine was validated, any drug company would be allowed to make it.

　　词汇突破：1.clinical trials 临床试验

　　2.publicly funded 公开募资

　　3.efficacy 功效，疗效（特别指药物）

　　4.a promising drug 有可能有效的药物

　　5.be found the final 进入最后阶段

　　6.validated 有效

　　主干识别：Most expensive stages of clinical trials could be publicly funded and conducted by independent laboratories

　　这个句子的难点就是主语的寻找! Final和most expensive 很容易被放在一起！一定要敢于切分！

　　切分成分：1.which measure the efficacy of a drug that has already been shown to be safe

　　定语从句

　　2. using another portion of the huge potential savings from cheaper drugs 状语（独立成句）

　　3.（Most expensive stages of clinical trials could use another portion of the huge potential savings from cheaper drugs.）

　　参考译文：当一种有可能有效的药物进入最后研发状态，最昂贵的临床试验阶段，也就是评估已经被证明安全的药物的功效的阶段，是可以公开募资的，也可以部分使用来自其他更廉价药物的潜在巨大结余资金。这个阶段可以由独立的实验室来完成。

　　再加一个第二句:

　　Once a medicine was validated, any drug company would be allowed to make it.

　　一旦一种药物被证明是有效的，任何医药公司都可获准生产这一药物。

　　今天的句子：

　　Unlike the east coast, with its party machines and opaque movements of money, California’s love of direct democracy, which weakens parties and allows individuals to be recalled from office, was supposed to keep politicians honest.
