A bicycle helmet is a helmet intended to be worn while riding a bicycle．They are designed to reduce impacts to the skull(头颅骨) of a cyclist in falls．However, there is a debate on whether helmets are useful for road cyclists．

The World Health Organization promotes the use of helmets as a strategy for preventing people' s heads from being injured by bicycle crashes or falls．Use of cycling helmets is supported by numerous groups in the United States. US-based cycling activist John Forester suggests that helmet wearing could prevent 300 deaths a year in the United States out of a total of 1530 preventable deaths．Public Health Law Research reports that there is enough evidence to establish that bicycle helmet laws are an effective public health intervention(干涉)aimed to reduce the number of head-related deaths．Received opinion in some countries is that bicycle helmets are useful and that every cyclist should wear one. Professional bodies elsewhere have agreed, such as the Swiss Council for Accident Prevention．

Mayer Hillman, a transport and road safety analyst from the UK, does not support the use of helmets, reasoning that they are of very limited value in the event of a collision（碰撞） with a car. He compares it to drawing conclusions on whether it is worthwhile to buy lottery tickets. Cyclists' representative groups complain that focus on helmets diverts(转移) attention from other issues which are much more important for improving bicycle safety, such as road danger reduction．The UK's largest cyclists' organization, the CTC, believes that the "overall health effects of compulsory helmets are negative.'' The same report estimated(估计) that universal helmet use would save the life of one child aged 0 to 15 each year．

Up to now, the debate is with no consensus（共识）, but an organization has published a review of studies in 2011, saying there is a good deal of evidence that those wearing a helmet are more likely to crash than bareheaded cyclists．

Bicycles are a great way to get around. They’re fun to ride, especially down hills. And, as you speed along the road, you might also think of ways in which you could improve your bike— make it safer, more efficient, or more comfortable. In fact, the two-wheeled machines make for some cool science projects.

This year's Intel International Science and Engineering Fair (ISEF), held last May in Cleveland, featured（had）three bicycle projects from three countries. Like many of the other experiments presented at ISEF, the bike projects showed that some of the most interesting scientific research often begins by taking a closer look at things you care about.

Renato Angulo Chu had even grander ambitions. The 12th-grader from Lima, Peru, wanted to address some of his country's economic troubles.

"I see a problem in my country," Renato said. "If you go to the forests in Peru, in some places you cannot find electricity. If you go with my bicycle, you can turn on the lights."

Renato, 16, spent 3 years designing his special Multibike. The device looks like a fixed exercise bike. It has wires fixed along the frame and a blender strapped (fastened) to the back. Turning the pedals operates the blender. The same principle can be used to sharpen knives or sweep city streets.

The Multibike can work either as a fixed bike or as a bicycle able to travel city streets and country roads. It's made from inexpensive materials, and the user gets exercise while pedaling to operate a machine.

"You pedal the bike, and you can mix any drink you want," Renato said. More importantly, he added, the same concept could be used to bring light to houses in remote regions of the rainforest.

1.What can we learn from the first paragraph?

2.Which of the following is true according to the passage?

3.The underlined word “address” in the third paragraph probably has the same meaning as _______.

4.Renato’s special Multibike has all the following  EXCEPT  ________.

5.It can be inferred that Renato’s special bicycle is mainly designed for ________.

Fear can be fun. Many young people queue up to ride very fast and scary roller coasters（过山车）， screaming but enjoying themselves, Other people like to read "goose bumps（鸡皮疙瘩）” books or watch horror movies at night, scared to death but feeling excited. Why do people like being scared?

Fear is an ancient way of surviving. Being scared makes animals, including humans escape from danger and save themselves. It is because of fear that we have lived through millions of years of evolution. Those who lacked a strong fear response were more likely to be killed, leaving the more fearful and careful to pass their genes onto the next generation.

How do scientists explain why shaking over such scary things is fun? "Some kids will go to a scary movie and love it and laugh over it, others will feel anxious and hide their faces and some won't even set foot in the cinema," said Ned Kalin, a US scientist. "Which kind of person you are depends partly on experiences you've had and partly on your genes."

What happens in the brain when something frightens you? Nerves that begin at the eyes and ears lead to a part of the brain called the amygdala, When you suddenly see a snake, for example, the amygdala makes you freeze, sweat, have a quickened heartbeat, or run very fast. However, seeing the snake also uses another part of the brain, the cortex. It analyzes the situation, and if it finds that the snake is only made of rubber it tells your heart and the rest of your body to calm down. Think of the amygdala as the engine and the cortex as the brake.

Back to the first question: Why do some people like to make themselves scared? "One reason is that we can play games with fear, find ways to reduce the scariness by looking away or thinking of something else," Kalin said. "To believe we have control over a situation gives us a feeling of power. " "Scary movies or novels are good practice to prepare young people for the real thing, Thrills such as roller coaster rides also go to the brain's pleasure centre. "

And there might be some evolutionary advantage to being able to adjust this system that is there to protect people.
