阅读下面这首唐诗，然后回答问题。
抽弦促柱听秦筝，无限秦人悲怨声。
似逐春风知柳态，如随啼鸟识花情。
谁家独夜愁灯影?何处空楼思月明?
更入几重离别恨，江南歧路洛阳城。

（1）颔联主要运用比喻（或“通感”）修辞筝声像柳条拂着春风，又像杜鹃鸟绕着落花啁啁啼血，以视觉写听觉，化无形为有形，更加形象可感
（2）“独”突出了孑然枯坐、愁对孤灯的形象，“空”表现离人远行、无所依人的情景；这两个字渲染了一种孤寂、凄清的气愤，淋漓尽致地写出了人物内心的忧郁和思念

It is also cheap. For millions of people suffering from arthritis, it is the only thing that works. Aspirin, in short, is truly the 20th-century wonder drug. It is also the second largest suicide drug and is the leading cause of poisoning among children. It has side effects that, although relatively mild, are largely unrecognized among users. Although aspirin was first sold by a German company in 1899, it has been around much longer than that. Hippocrates, in ancient Greece, understood the medical value of tree barks and leaves which today are known to contain a chemical found in aspirin. During the 19th century. there was a great deal of experimentation in Europe with this chemical, and it led to the introduction of aspirin. By 1915, aspirin tablets were available in the United States. A small quantity of aspirin relieves pain and inflammation. It also reduces fever by affecting some of the body’s reactions. Aspirin is very irritating to the stomach lining. The best way is to chew the tablets before swallowing them with water, but few people can stand the bitter taste. Some people suggest crashing the tablets in milk or orange juice. |
