Several interesting American museums tell about health subjects. One is the Doctor Samuel D. Harris National Museum of Dentistry. It is at the University of Maryland in Baltimore. That is where the first college in the world to train dentists began. The museum tells about the history of the medical treatment of teeth. Visitors can see some frightening devices that once were used to remove infected teeth. They also can see sets of teeth made of animal bone. They were made for a famous American —— the first President, George Washington.

Most people do not consider a visit to the dentist their idea of a good time. However, the director of the museum says he wants to make the museum a funny place to visit. He says he also wants to teach visitors about the importance of taking care of their teeth.

Another museum collects devices that help people hear. The Kenneth W. Berger Hearing Aid Museum is at Kent State University in Kent, Ohio. The museum has more than three-thousand hearing aids from around the world. They include old and strange devices. Some hearing aids were made to look like other objects. That is because in the past many people did not want anyone to know they were wearing a hearing aid.

阅读理解与欣赏

  我不由得停住了脚步。

  ①从未见过开得这样盛的藤萝,只见一片辉煌的淡紫色,像一条瀑布,从空中垂下,不见其发端,也不见其终极。只是深深浅浅的紫,仿佛在流动,在欢笑,在不停地生长。紫色的大条幅上,泛着点点银光,就像迸溅的水花,仔细看时,才知道那是每一朵紫花中的最浅淡的部分,在和阳光互相挑逗。

  这里春红已谢,没有赏花的人群,也没有蜂围蝶阵。有的就是这一树闪光的、盛开的藤萝。花朵儿一串挨着一串,一朵接着一朵,彼此推着挤着,好不活泼热闹!

  “我在开花!”它们在笑。

  “我在开花!”它们嚷嚷。

  每一穗花都是上面的盛开、下面的待放。颜色便上浅下深,好像那紫色沉淀下来了,沉淀在最嫩最小的花苞里。②每一朵盛开的花就像是一个小小的张满了的帆,帆下带着尖底的舱,船舱鼓鼓的;又像一个忍俊不禁的笑容,就要绽开似的。那里装的是什么仙露琼浆?我凑上去,想摘一朵。
