(2018·山东临沂)What was discovered by accident? The answer is penicillin (青霉素). It kills germs. By killing germs, it saves lives. Suppose you are sick. You go to a doctor. She examines you. She says you have a “staph” infection (葡萄球菌感染). She gives you some medicine. You take it. The medicine knocks out the staph. Soon you are well. Before penicillin, this would not happen. Staph was almost sure death.

Everyone wanted a medicine. Laboratories worked day and night. They grew the staph in small dishes. Then they tried to kill it. Nothing worked.

The laboratory dishes had covers on them. They kept things from falling into dishes. Molds (霉菌) were a big worry. They are always in the air. You can’t see them. They’re too small. There are thousands of different molds. Molds can make an experiment (实验) fail. That’s why dishes are covered.

Dr. Alexander Fleming was working to kill the staph germ. He worked for years. One day he took a cover off a dish. He looked inside. There was a thick growth of staph germ. There was also some mold. Then he saw something strange. Where the mold was, there was no growth of staph. This is what Fleming probably thought. “By accident, I found a mold to kill the dreaded staph.”

This is how penicillin was found. But here’s the real miracle (奇迹). There are thousands of kinds of molds. But only one kind can kill staph. The mold must have fallen into the dish a few days before. The cover was probably off only a few seconds (秒). In those few seconds the right mold fell into the right dish. Another man might have thrown the dish away. But Fleming was very careful and smart. He understood what the mold did. How lucky the humans were!

Shang Yang was a politician of the Qin state. He was very wise and forward-thinking(有远见的). He worked out several reform plans for the state, including focusing on farming and giving rewards(奖赏) to soldiers who were successful during war.

But at the beginning, these reforms were not easily carried out. Only a few people in the state understood Shang's talent and the advantages of his plans. Most people had little trust and confidence in him.

To solve this problem, Shang came up with an idea. He ordered some soldiers to put a thin wooden pole at the south gate of the Qin state capital. This attracted many people. Then, in front of the crowd, he said loudly: "People of Qin, whoever takes this pole to the north gate will get a reward of 10 gold pieces."

It was a simple task and the reward was big. Some time passed and no one stepped forward. They all thought that Shang was joking. Hearing no answer, Shang stepped forward and said, "I will increase the reward to 50 gold pieces."

The words sounded even more unbelievable. Finally, a man from the crowd came forward to take the pole. He put the pole on his shoulders and walked to the north gate. True to his word, Shang paid the man 50 gold pieces.

Soon, the people were saying that Shang was a man of his word. When he began promoting(推行) his reforms, the people followed and did not question him.
