Reading for Understanding
In this short reading, you will read a little about the history of sterilization. The purpose
of this exercise is to read for understanding. For this reason, it is a little more difficult than the
reading in the lesson. For example, there is no preview exercise or any help with the vocabulary.
Therefore, you must read carefully but quickly. Then do the exercise.
Look at the reading again if necessary, but do not look at your dictionary.

Sterilization during Surgery
In the past, no one knew how disease spread from person to person. However, in the 1800s,
several doctors and scientists proved that microscopic bacteria caused diseases, although they
could not be seen without a microscope. The names of some of these famous people were van
Leeuwenhoek, Semmelweis, Pasteur, and Lister.
