参考解析
解析：题干意为“为什么法国科学家没有继续制造止痛药？”因为它很难制作。短文第一段最后两句提到“1853年，法国的一位科学家以柳树为原料制成了一种混合物，这种混合物不伤胃。然而这种混合物很难制造，他没有试着生产和销售”，故选D。
题干意为“为什么霍夫曼一直在寻找一种止痛药？”他父亲处于痛苦之中。短文第二段前两句提到“1897年，德国的霍夫曼也用水杨酸制成了一种混合物。他先在自己身上尝试，然后给自己的父亲用，因为他父亲年纪大了并且处在痛苦中”，故选B。
题干意为“拜耳开始生产阿司匹林因为它能有效止痛。”短文第三段前三句提到“霍夫曼在德国的拜耳公司工作，他将自己的新药拿给经理，经理测试了新药，发现它非常有效，于是拜耳决定生产这种药”，故选C。
题干意为“拜耳的阿司匹林是最早在美国销售的阿司匹林。”短文倒数第二段第三句提到，“在美国拜耳有药物的专利权，只有拜耳可以在美国制造和销售阿司匹林，最后，拜耳在美国不但单独拥有阿司匹林，其他公司也可以在那里制造。但是，拜耳的阿司匹林 一直是最出名的，多年来一直是市场领导者”，故选B。
题干意为“市场上出现新的止痛药之后，阿司匹林结局如何？”它的新用途被发现。短文最后一段第五句提到“医生们注意到，服用阿司匹林的病人比其他人得心脏病的几率要小”，故选C。
