What would the world be like if cars could drive themselves? Imagine seeing an empty car passing by on its way to pick up its owner, or a car full of passengers who are reading, listening to music or even sleeping. But none of them are worried about the road ahead.
Well, all of this could be the future of driving. There are several companies, including Google, working on driverless cars. So far, no Google self-driven cars have gotten a traffic ticket (罚单), but some of them have been in accidents when other cars hit them.
These cars are now still in the testing stages (阶段). But, if the tests are successful, these electric self-driven cars could be put into use very soon.
The cars are so special that they can take the place of drivers during certain situations. They are able to park themselves, or slow down when they notice objects close by. They can also control the speed if there is danger.
Scientists and engineers believe, with the help of wireless signals (无线信号) , cameras and GPS, creating a safe self-driven car might be possible. The cause of deadly (致死的) road accidents is usually careless drivers or bad conditions. The self-driven car may be able to prevent these. However, some people don’t like the idea. American lawyer Whit Drake does not believe these cars are safe. He thinks that technologies can also be mistakes.
Complete the chart according to the passage with only one word for each blank.

九年级英语阅读单选简单题查看答案及解析
In the 1966 science-fiction (科幻) film Fantastic Voyage, a team of scientists and doctors are put into the body of an ill man to fix his body.
Such an idea, while fun, sounds surprising to many. But what if it were possible to treat an illness like cancer (癌症) by putting tiny pieces of something into the body to not only find the cancer, but also destroy it without harming anything else? Although it may seem like science fiction, tools like this are now being developed and may, in fact, become common in the near future – thanks to research now being done in the field of nanotechnology (纳米科技).
The main thing to know about nanotechnology is that it’s small – really small. Using this technology, it will be possible to discover cancer at a certain level where there are perhaps only a thousand bad cells (细胞). Compare this to what happens today: Doctors can discover cancer only after the dangerous cells have increased into the millions. One of the advantages of discovering and treating cancer at an early period is that the cells are less likely to become resistant to medicine treatment. In later period, cancer cells often change and get used to certain medicine so quickly that many medicines become ineffective.
Once a certain type of cancer is discovered, nanotechnology will also completely improve the way it is treated. Right now, most cancer treatments kill not only cancerous cells but the healthy ones as well, causing a number of side effects in people, such as hair loss and bad pain. Nanotechnology will allow doctors to destroy cancerous cells without harming healthy cells.
Unluckily, even though nanotechnology has great possibility for medical achievement, there are serious concerns that it could have bad environmental and health effects. Many scientists believe that governments should give more money for safety-related studies – to make sure that these tiny pieces of something do not get into our food and water and cause serious problems.
Meanwhile, research into the uses of nanotechnology continues and it’s developing quickly. Even ten years ago, many of these uses “would have seemed pretty unrealistic,” says Chemist Vicki Colvin. Perhaps that old movie, Fantastic Voyage, isn’t hard to believe after all.
1.According to the passage, nanotechnology ______.
A.may cause a number of side effects such as hair loss
B.may help discover and treat cancer before it is too late
C.can be used to kill both cancerous cells and healthy ones
D.can discover cancer and treat it completely in later period
2.The words “resistant to” in Paragraph 3 probably means “______”.
A.undestroyed by B.useless for C.unsatisfied with D.harmless to
3.Which of the following would be the best title for the passage?
A.The Advantages of Nanotechnology.
B.The Near Future of Science Fiction.
C.A Tool for Creating Medicine?
D.A Treatment for Cancer?

You may have been told before not to be afraid of anything. Fear is often associated with weakness. Fear is something to be avoided.
But that’s not true, according to Time For Kids magazine. Fear can be good for us.
Fear tells us about danger. Without fear, we wouldn’t know to run away from a tiger or step back from a cliff.
In a study published in the Justice Quarterly journal in August, researchers from Michigan State University said that a healthy fear of crime keeps teenagers away from potentially(潜在地) dangerous people, places, and activities.
Fear makes us jump, scream and sweat. But interestingly, sometimes we make ourselves feel fear on purpose. Think about scary(恐怖的) books and movies, and also the long lines for a scary roller coaster(过山车)ride.
Margee Kerr, a US sociologist, explained why to Time For Kids.
Fear fills our brain with healthy chemical substances, especially endorphins (内啡肽) and dopamine (多巴胺), and these things create feelings of happiness and excite us, according to Kerr.
In addition, when you’re scared, your body produces a chemical which helps people bond with each other.
“Watch people walking out of a haunted (闹鬼的) house, and you’ll see lots of smiles and high fives (击掌),” Kerr told Time For Kids. That also explains why schools and companies organize challenging trips and physical activities to build up team spirit.
People experience and deal with fear in different ways. If you happen to be a “coward” who gets scared easily, don’t worry. There is some evidence that being scared can help a person manage stressful situations.
Kerr said that things like giving a report in front of your class or performing in a school play help build a sort of endurance (忍耐力) to fear that makes us more confident.
“You become more comfortable with the physical experience of fear, and so you’re better able to work through it during tense situations,” said Kerr.
So learn to love your fear. It only grows when we forget how helpful our fear is trying to be.
1.Why is a scary roller coaster ride helpful to people according to the passage?
A.It improves people's ability to live in the modern world.
B.It makes people less cowardly and more confident in life.
C.It causes the brain to produce chemicals that make people happy and excited.
D.It teaches people how to keep away from things that could be dangerous.
2.The underlined part “bond with” in Paragraph 8 probably means .
A.get closer to B.fight against
C.pay attention to D.be more careful with
3.What is the right attitude toward fear according to the passage?
A.Avoid being involved (涉及) in scary situations.
B.Experience it as often as possible.
C.Consider it as a sign of weakness.
D.Enjoy healthy fear occasionally (偶尔地).
4.What's the passage mainly about?
A.People's misunderstandings about fear. B.Different ways to deal with fear.
C.The benefits (好处) that fear brings us. D.A new study about fear’s harm.

The world's nights are getting surprisingly brighter. This is bad news for all kinds of creatures, including humans - as light pollution is becoming worse, taking away the darkness of night almost everywhere.
Satellite* observations* made by researchers show Earth's artificially-lit* outdoor area grew by 2% a year from 2012 to 2016. So did night time brightness. Light pollution was even worse than that, according to the German-led team, because satellites cannot observe some of the LED lighting, especially blue light.
"Honestly, I had hoped that with LEDs we were improving the situation, for this new lighting technology has been developed to use less energy. But it turns out quite disappointing. ", said Kyba, the lead author of the study.
"Asia, Africa and South America, for the most part, have seen an increase in artificial night lighting. The cities in developing nations are brightening quite rapidly. Other bright places include greenhouses in the Netherlands and areas of agriculture. More and more places are fixing outdoor lighting because of its low cost and the growth in communities' wealth," the scientists said.
One of the co-authors, Franz Holker of the Leibniz Institute of Freshwater Ecology and Inland Fisheries in Berlin, said things were already in a terrible situation.
"Many people are using light at night without really thinking about the cost," Holker said. "Not just the economic cost, but also the cost that you have to pay for environmental damage."
The effect from the increasing artificial light is obvious, according to the researchers. People's sleep can be marred, which in turn can hurt their health. The life of birds, fish, insects and bats can be harmed. Plants can have longer growing periods. And people may forget about seeing stars or the Milky Way if the light pollution continues.
Kyba and his team suggest avoiding bright lights whenever possible and using more useful ways to shine light on places such as parking lots or city streets. For example, dim, closely spaced lights can provide better visibility than bright lights that are more spread out.
1.Why is light pollution becoming worse according to the passage?
A.Because LED lighting gives off blue light.
B.Because there is increasing artificial lighting.
C.Because people can pay for the electricity bill for home.
D.Because scientists didn't suggest avoiding artificial lighting.
2.What can we learn from the passage?
A.We can use bright lights in city streets.
B.LED lighting can help reduce light pollution.
C.Maybe we can't see the stars because of light pollution.
D.The cities in developing nations don't fix outdoor lighting.
3.What does the underlined word "marred" probably mean?
A.recorded B.controlled C.improved D.influenced
4.What's the best title of the passage?
A.The Disadvantages of LEDs B.Brighter Nights Are Dangerous
C.What Causes Light Pollution D.Ways to Reduce Light Pollution
