(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!

Our teacher often tells us in the river. It’s dangerous.

A. not swim B. not to swim C. to swim D. swimming

B 【解析】 句意:我们老师经常告诉我们不要在河里游泳。这很危险。此题考查不定式。题目中的 tell(告诉)是谓语,句子在连接第二个动词时,需要用 to 来连接,将其非谓语化,既不定式:to +动词原形。可以排除 A 和 D。根据句意:游泳是危险的。所以可以推断出老师是告诉我们不要去游泳。因此选择不定式的否定形式,即 B 选项。

— Would you like to go swimming with me, Tom?

— Sorry, but our teachers always tell us in the river.

A. don’t swim B. not swimming C. not to swim D. to not swim

C 【解析】 句意:——你愿意和我一起去游泳吗,汤姆?——对不起,但是我们的老师总是告诉我们不要在河里游泳。tell sb. not to do sth.告诉某人不要做某事,结合句意可知,答案为C。
