In 16th-century England, purple was　 　for the kings family members. Queen Elizabeth I's clothes were purple, but ordinary people were not allowed to　 　the color.
In 1856, William Perkin, an 18-year-old　 　student, noticed something strange while doing an experiment (实验). The chemicals (化学药品) he used to clean his instruments　 　
with the chemicals he used in his experiment and produced a bright purple color. This　 　led Perkin to start a company using this chemical mixture to make purple dye. The dye was much
　 　than sea--- snail dye. Thanks to Perkin, now anyone can afford to wear purple clothes.

When Goldie Nejat began developing robots in 2005, she spent much of her time knocking on
doors to let people know how her robots worked but few showed interest, "But now, it's different, " says Nejat. "People calling from around the world ask when my robots are going to be ready."
Nejat's robots are designed to fill an increasing need：care giving for the old. The population of
the people over age 80 will be 426 million in 2050, three times larger than that now.
Such robots could be especially useful for patients with Alzheimer s disease(阿尔茨海默病).
They can help with everyday activities from preparing food to reminding(提醒) the patients of taking their medicine. They can also play games with patients to keep them active.
Some have worried that care giving robots might reduce(减少) human interaction(互动) and
cause more humans to lose their jobs. "But the aim is to support human care, not to take the place of it, " says Brian Scassellati. He has tested robots with different patients, and found that daily interaction with robots can help children with autism spectrum disorder( 自闭症障碍) improve social skills.
As a field grows, scientists aim to understand human robot relationships better.Do robots offer advantages because they don't have feelings and don't give opinions？Will patients lose interest？
"One thing is clear, " Scassellati says. "Robots can provide care for the customers and the need for that will increase in the future. "
( )8. Nejat's robots are designed to 　 　.
A. work in the factory B. make phone calls
C. take care of the old D. knock on doors
( )9. The writer starts the passage by 　 　.
A. telling two stories B. comparing two facts
C. raising a question D. giving an example
( )10. The main idea of Paragraph 3 is 　 　.
A. what the robots can do B. what serious problems the robots cause
C. what the old people can do D. what the old people think of the robots
( )11. According to Scassellati, we can infer that Nejat's robots 　 　.
A. will have feelings soon B. can take the place of humans
C. should be produced more D. won't give their own opinions
D
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 medicine. They worked in the lab day and night, and they grew the staph in
small plates and tried to kill it, but 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 that 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 ago. The lid was probably only open for a few seconds, and right then, the mold fell into the 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 !
( )12. During the experiments to find a medicine for staph infections, 　 　.

C. mold was kept in small dishes D. staph was grown in small dishes
( )13. The last paragraph suggests that　 　.
A. accidents happen to everyone
B. the careful person does not have accidents
C. the careless person will miss valuable chances
D. luck is enough when doing scientific experiments
( )14. Most of this passage is written by　 　.
A. telling an unusual story B. showing the results of experiments
C. offering some reasons D. giving some advice
( )15. This passage is mainly about　 　.
A. medicine for a staph infection B. useful accidents
C. Dr. Fleming's research D. discovering penicillin

My invention is a flying bike. It is a special bike with two wheels and two wings. The flying
bike can drive both on the ground and in the air. It can be used to take photos and people can talk with it. As a very special bike, it is fast, and it is environmentally-friendly because it is driven by solar energy. This is my flying bike, which is made by myself alone in my spare time. If it is used in our life, I will have two improvements. I will suggest the engineer use light irons of high quality to make the frame, and make the wheels as large as possible.
Thank you very much.
