In the summer of 1885, nine-year-old Joseph Meister was very ill. He had been attacked by a sick dog that had rabies(狂犬病), a very dangerous disease. His doctor tried to help him, but there was no cure for rabies at that time. The doctor told Joseph’s parents that perhaps there was one man who could save Joseph’s life. His name was Louis Pasteur.

When Pasteur was young, he was especially interested in medicine, so he spent many hours every day with the chemist (药剂师）who lived in his small town. At that time, the chemist had to make all the medicines himself. Young Louis enjoyed watching the chemist as he worked and helped those people who came to him each day. Pasteur decided that one day he would help people, too.

As a school boy, Pasteur worked slowly and carefully. At first, his teachers thought that young Louis might be a slow learner. Through elementary school, high school, and college, Pasteur worked the same way. In fact, he was not a slow learner, but a very intelligent young man. He became a college professor and scientist, and he continued to work very carefully.

Because of Pasteur’s patience, he was able to make many observations and germs (细菌). Pasteur was studying about the germs that cause rabies when Joseph Meister became ill. In fact, Pasteur believed that he had a medical treatment for rabies, but he never gave it to a person before. At first, Pasteur was afraid to treat Joseph, but the doctor said the child was dying. Pasteur gave Joseph an inoculation (预防接种）every day for ten days. Slowly, the child became better.

During his lifetime, Pasteur studied germs and learned how they cause diseases in animals and people and also studied the way to prevent diseases. On September 28, 1895，Louis Pasteur passed away. The work of this great man has been of great help to modern medicine.

D. Answer the following questions (根据短文内容，回答下列问题）

In 1826, a Frenchman named Niepce needed pictures for his business. But he was not a good artist. So he invented a very simple camera. He put it in a window of his house and took a picture of his garden. That was the first photo.

The next important date in the history of photography was in 1837. That year, Daguerre, another Frenchman, took a picture of his reading room. He used a new kind of camera in a different way. In his picture you could see everything very clearly, even the smallest thing. This kind of photo was called a Daguerreotype.

Soon, other people began to use Daguerre’s way. Travellers brought back wonderful photos from all around the world. People took pictures of famous buildings, cities and mountains.

In about 1840, photography was developed. Then photographers could take pictures of people　

and moving things. That was not simple. The photographers had to carry a lot of films and other machines. But this did not stop them, for example, some in the United States worked even harder.

Mathew Brady was a famous American photographer. He took many pictures of great people. The pictures were unusual because they were very lifelike.

Photography also became one kind of art by the end of the 19th century. Some photos were not just copies of the real world. They showed feelings, like other kinds of art.

1.Was the first photo a picture of a window of a house?

2.What was the Daguerreotype?

3.If a photographer wanted to take pictures of moving things in 1840, what did he have to do?

4.Why were Mathew Brady’s pictures special?

5.What does this passage mainly tell us?

6.Can you name another kind of art that shows feeling?

Joseph really felt very happy. When he arrived at his seat in the classroom that morning, he found an invitation on his desk. It was from several of his classmates asking him to join them on a camping trip. This was the first time he was asked to join in an out-of school activity. Why were they asking him now? Nobody seemed to like him. In fact, he had been so lonely that he drowned his feelings with food. As a result, he had put on a lot of weight, and this gave the kids something more to make fun of him.

Celina, who was standing near Joseph when he read the invitation, went out quickly to tell the others that the trick had worked. Everyone was pleased that Joseph thought that was true. But there was no camping trip. The whole thing was made up.
