      Roosegaarde, an artist and designer from Dutch has thought of a device(装置). He hopes it will make Beijing's sky clear again and help the people with masks breathe fresh air again in Beijing.
     An electromagnetic field(电磁场) will pull the dirty particles in the air to the ground, and then they can be easily cleaned.
Roosegaarde says, "It's like when you have a balloon which has static electricity(静电) and your hair goes toward it. Smog happens the same way as the hair."
      His workplace has reached an agreement with the Beijing government to test the technology in one of the capital's parks.  Beijing's skies are regularly covered by grey smog. Serious cases of air pollution are often reported in Beijing. Roosegaarde says an indoor test has already shown it works well and he is confident of the results. With the help of a team of scientists and engineers, he is sure that the device can be worked outside.
     "Beijing is a very good place to test the device because the smog in Beijing is quite low and there's not so much wind." says Roosegaarde. "We'll be able to make the air pure but the most difficult thing is to remove the smog. As a result, you can see the sun again."
     Roosegaarde also reminds us that his aim is not only to give a plan to solve Beijing's dirty air pollution but also to make people pay attention to the environment problem. He adds, "This is not the real answer for smog. The real answer to do with it is clean cars, different industry and different lifestyles. " However, he hopes the project will make the citizens realize the differences between clean air and smog-filled air.

(1)、The device works by_______.

A、helping keep the particles out with more masks B、pulling particles to the ground with an electromagnetic field C、absorbing hair with a balloon with static D、creating clean air and letting it out into the sky
(2)、What does Roosegaarde use his device for?

A、To make smog. B、To make the air clean C、To make static electricity D、To make Beijing's parks beautiful.
(3)、After reading the passage, we can know_______.

A、the device doesn't work well indoors B、the people with masks can breathe fresher air C、Beijing government agreed to test the device D、clean cars aren't helpful to the environment in Beijing
(4)、Roosegaarde hopes people in Beijing can_______.

A、pay attention to air pollution and solve the problem finally B、invent more devices to clean the smog in Beijing C、drive modern cars and try different lifestyles D、realize how serious the pollution they're facing is

    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 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. 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. 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!
