1 . When you hear the beginning of your favorite song from the radio, suddenly your neck is covered in goose bumps.
It's such a thing that a group of scientists call “skin excitement”—a feeling of cold caused not by a drop in temperature or sudden scare, but by the sense of beauty. “Skin excitement” can come from a song, a painting, a moving movie scene, or even a beloved memory-pretty much anything that causes the giving out of pleasure-soaked dopamine in your brain. But it does not come for all of us.
Your favorite music uncovers a lot about your personality，and so does how you respond to that music. Studies suppose that as few as 55 percent of people experience “skin excitement” when listening to music. And if you count yourself among this group, the goose bumps on your skin aren't the only giveaway—scientists can read it in your brain, too. In a new study published in the journal Social Cognitive and Affective Neuroscience, Harvard researchers performed brain scans on 10 students who said they reliably got cold when listening to music, and 10 students who didn't. They found that the cold-prone brains may really be excited by stronger emotions.
Cold-prone brains are generally more likely to show stronger emotional intelligence than no-cold brains. Cold-prone minds tend to have unusual active imagination, reflect more deeply on their emotions, and appreciate nature and the beauty of music and art to a stronger degree than no-cold brains.
So, what type of music causes the chills? It seems that the type is not so important; participants in the new study reported getting cold from songs of every kind. And any song connected with a strong emotional memory of the listener can produce the most reliable results. For me, that's the song Sailing to Philadelphia by Mark Knopfler, which I listened to as a kid in the car with my dad, on the way to the summer camp.

2 . Can trees talk? Yes, but not in words. Scientists have reason to believe that trees do communicate with each other. Not long ago, researchers learned some surprising things. First a willow tree attacked in the woods by caterpillars changed the chemistry of its leaves and made them taste so terrible that they got tired of the leaves and stopped eating them. Then even more astonishing, the tree sent out a special smell—a signal causing its neighbors to change the chemistry of their own leaves and make them less tasty.
Communication, of course, doesn’t need to be in words. We can talk to each other by smiling, raising our shoulders and moving our hands. We know that birds and animals use a whole vocabulary of songs, sounds, and movements. Bees dance their signals, flying in certain patterns that tell other bees where to find nectar for honey. So why shouldn’t trees have ways of sending message?

4 . Twenty-five years ago, most young Britons wanted a career in law, to be a doctor, or, if they were creative enough, to take up singing. But today, things stand differently.
According to a survey by Tesco Mobile, a UK company, the “dream job” of young people aged between 16 and 25 in the UK is a video blogger, or “vlogger” (视频博主). The survey, carried out among 1,002 people, found that as much as 40 percent of them put vlogger as their number one choice on a list of ideal careers.
This change is undoubtedly as a result of the Internet and social media. They have made it so much easier to reach audience of the world, without having to enter a career in show business in the traditional way.
In the past, the biggest stars were trained by the Hollywood studios; now, anyone with a computer camera can become a star. Vloggers are the big stars of today because they are normal people interacting with their fans about everyday life.
However, what people see is only the bright side of being a vlogger and they fail to notice the fact that only those who are successful earn fame and fortune. For every success there are hundreds of others who never get off the starting line. There are the dreams that come true and the dreams that remain dreams forever.
Although being vloggers is popular, some young people choose to follow careers that don’t necessarily earn them fame, but allow them to make good use of the Internet to share their hobbies. Young Israeli David Leshaw, for example, runs a business called the Finishers Club. It’s an online platform for runners to keep a record of their races. His job allows him to express his enthusiasm, and is always a learning experience. And that's enough for him.

5 . Growing up, your mom probably kept telling you that you should make your bed in the morning. But it’s time to put this little habit to rest. In fact, it could be better for your physical health to leave your bed unmade during the day, experts say.
What allows you to be extra lazy? Dust mites (尘螨). These little creatures live on our dead skin and produce allergens that you could breathe in while you are sleeping. And about 1.5 million dust mites are spending every night with you right now. Thankfully, there’s an easy way to get rid of them: Don’t make your bed in the morning.
Researchers at Kingston University have found that dust mites live well in warm and humid (潮湿的) environments but die in dry conditions, the BBC reports. Making your bed every morning produces a good place for these little creatures, but keeping your bed sheets open kills them off. Sometimes it pays to be a little lazy.
“Something as easy as leaving a bed unmade during the day can remove humidity from the bed sheets and mattress. If dust mites won’t be able to get enough water, they’ll finally die,” Dr Stephen Pretlove told the BBC.
Fewer dust mites means fewer health problems, too. However, not all experts agree; according to some, most homes are wet enough for dust mites to live on, no matter what we do. “I find it hard to believe that just not making your bed would have any effect on solving the problem,” Professor Andrew Wardlaw from Britain said.
1. What do experts suggest us doing in Paragraph 1?| A．Following our mothers’ advice. | B．Enjoying good physical health. |
| C．Keeping away from bad habits. | D．Leaving our bed unmade in the morning. |

| B．It’s easy to keep dust mites away from our home. |
| C．Dust mites have nothing to do with health problems. |

| C．Science. | D．Business. |
6 . The words “protect animals” appear everywhere in books and on screens, because some animals are even in danger of dying out. But sometimes the reality can be a little different from what people read or watch.
About 300 black bears were killed in Florida, the US, in October, 2015. It’s been the first bear hunt in the state since 1994. Local officers explained that the black bear population (族群) had grown to 3,500 and become a menace to local people. In the past two years, bears have hurt at least four people in Florida.
Months ago, the Swiss government allowed the locals to kill a wolf. This was because the wolf killed 38 sheep, and it was a great loss to some local farmers. Days ago in China, three old men were caught by the police for killing a sorrow (鬣羚), a kind of protected animal. They said they killed the animal because it ate the plants they grew.
However, these stories don’t always mean that animal protection stops because of human interests especially when it is related to economic (经济的) development. A man named Zhou Weisen set up a wild animal base in Guilin, Guangxi. He saved over 170 tigers and about 300 bears. His base also offered jobs to local people.
“There may never be a standard answer to the question of whether we should give more attention to the environment or human development,” said Robert May, a British expert at Oxford University. “But we shouldn’t put either one to one side, as the future is uncertain.”

7 . Food sometimes gets poisoned(中毒) with harmful things. A person who eats such food can get an illness called food poisoning. Food poisoning is usually not serious, but some types are deadly. The symptoms of food poisoning usually begin within hours of eating the poisoned food. Fever is one of the most common symptoms.
Certain microorganisms(微生物) cause most types of food poisoning. Bacteria and other microorganisms can poison eggs, meat, vegetables, and many other foods. After entering the body, these tiny living things release(释放) poisons that make people sick.
Some chemicals(化合物) can also cause food poisoning. They are often added to food while it is being grown, processed, or prepared. For example, many farmers spray chemicals on crops to kill weeds and insects. Some people may have a bad reaction to those chemicals when they eat the crops.
Some plants and animals contain natural poisons that are harmful to people. These include certain kinds of seafood, grains, nuts, seeds, beans, and mushrooms.
When people handle food properly, the risk of food poisoning is very small. Microorganisms multiply rapidly in dirty places and in warm temperatures. This means that people should never touch food with dirty hands or put food on unwashed surfaces. Food should be kept in a refrigerator to stop microorganisms from growing. Meat needs to be cooked thoroughly to kill any dangerous microorganisms. People should also wash food covered with chemicals before eating it. Finally, people should not eat wild mushrooms or other foods that grow in the wild. Some of these foods may contain natural materials that are poisonous to humans. In addition, some types of fish can be poisonous.
Most people recover from food poisoning after a few day of resting and drinking extra water. If people eat natural poisons, they must go to the hospital right away to have their stomachs emptied.
