the same receptors in the brain。题干问的是新药tasimelteon的作用机理，定位到第三段。根据similar effect定位到最后一句。原文提到，tasimelteon这种物质与melatonin一样都与the same receptors in the brain有关联。原文中用的是the same…as…结构，题干把as前后的比较对象用一个they都包括了，connect with对应原文中的binds to。直接从原文摄取答案即可。
同位语处设题。本题在tasimelteon的同位语处设题。注意连接词as前后主句和从句中的主语在题干中被糅在了一起。
