Why does something that smells so good taste so bad? Many people are curious about this, but now scientists say they have found the answer – it lies in our “second sense of smell,”according to the Telegraph.

“We have two senses of smell,”explains Barry Smith, professor of the University of London. “One is when you breathe in things from the environment, and the other is   when the air comes up the nose and is breathed out through the nose.”

When we drink coffee, for example, the act of swallowing(吞咽) sends a burst of smell up the back of our nose from inside the mouth. This wakes up the second sense of smell in our brain. But it is weaker and less sensitive to flavors(味道). As a result, it gives us a completely different feeling.

In fact, the second sense of smell plays a big part in our eating experience. It may be common sense that we smell through our nose and taste using our tongue(舌头). But the truth is 80 percent of what we think of as taste actually reaches us through smell. Just hold your nose while eating and you will notice that your tongue can only catch a very small part of the favor.

Researchers from Cambridge University tried to answer these questions. They asked 350,000 people from 50 different countries. Then, they found that musical preferences depend on personality (性格). Outgoing people prefer danceable music with strong beats such as rap. Country music fans are shown to be more serious in their jobs. One of the findings is quite interesting. The researchers thought that people with much stress (压力) should like sad music or rhythmic (有节奏的) music. But it turned out that these people dislike these two kinds. Instead, they like loud music better. Maybe they like to listen to this kind of music to lower their stress.

The researchers also found that climates may affect people’s musical preferences and personalities, too. People in hot weather prefer danceable music. They are more outgoing. This may be a result of longer daylight hours. They advised people to go outdoors to dance.

Of course, nothing is clear-cut. We may not group people simply by their musical tastes. The study just showed us that people of different cultures are more similar than we think. “People are grouped by language and culture,” said Dr. David Greenberg. “But if an outgoing person in one place likes the same music as outgoing people in other places, then we can say that music is really like a bridge.”

【推荐1】Amy wanted a mobile phone as her birthday gift, because most of her classmates had one, but she knew her parents couldn’t afford it.

One day, when she woke up, she found a new mobile phone on her desk. How excited she was! This was the phone that had appeared in fashion magazines.

She played with the phone on the way to school. And the teacher was already there when she arrived at school. Amy was very embarrassed. She looked at her new mobile phone and whispered, “I didn’t want to be late...”

Everything changed with her thought. She went to school on time with her new mobile phone.

She was surprised at that. She turned on the phone and found there was a sentence on the screen, “Every dream will come true.” Since then, she always asks the phone for help. As a result, she has become lazier and lazier. Her teachers and parents were very disappointed with her and her classmates didn’t like her any more.

When the term exams came, Amy asked the mobile phone for help again, but things turned bad. She got the lowest mark in the class. She wanted to throw it away, but when she did, the phone would come back into her hand. Amy was so scared that she cried out, “I don’t want the mobile phone any more.”

She woke up to find that the terrible experience had been just a dream.

【推荐2】When I was in the sixth grade, my teacher asked our class the question, “What does ‘doing the right thing’ mean to you? “She asked us to think about it over the weekend, and to talk to anyone else who we thought might have a good answer. By Monday, we were to hand in an article on it, and be prepared to live up to our answers. We should match word to what we do.

The whole weekend, I tried to come up with something special and easy to do. I talked to my parents, called my grandmother, and asked my next door neighbor. Everyone had good answers, but I didn’t feel like I could do them.

On Sunday afternoon, I met my four-year-old cousin Andrea. When Andrea was watching TV, I started to write my article. Soon I felt a pair of eyes on me. It was Andrea.

“What are you doing?” she asked.

“I have to write an article about what doing the right thing means to me.” I answered. Andrea laughed.

“That’s easy,” she said.

“OK, tell me the answer,” I said.

“Doing the right thing means being nice to your family and friends. Do what your mum says. Never lie. Take a bath when you’re dirty. Don’t waste water and electricity…”

I looked at Andrea amazingly. Not only had she answered a very difficult question for me, but I could easily follow all of her rules. So when I wrote my article, I included the story about Andrea and how she had answered my question.

Two weeks later, I received an A*along with a little note my teacher had written: “Always do the right thing—and give Andrea an A*, too!”

【推荐2】All live poultry(家禽) markets in Shanghai will be closed from April, 6th after H7N9 bird flu virus was found on a farm product market, the government announced. On the morning of April, 5^th, 20,536 birds were killed at the Huhuai market, where the virus was found the day before.

Up to now, the city has reported six cases of H7N9 bird flu, and four people have died from the virus (病毒). The other two, an adult and a 4-year-old boy, remain in a hospital.

So far, 16 H7N9 cases have been confirmed(确诊) in China. Apart from the Shanghai cases, six are in Jiangsu, three in Zhejiang and one in Anhui provinces. Two people died in Zhejiang.

Shanghai's two surviving patients "are getting better", Wu Fan, chief of the city's Center for Disease Control and Prevention, said at a news conference (记者招待会) on Friday. "Not all H7N9 cases lead to worse illness."Wu suggested that people with a fever and runny nose who suspect(怀疑) they have the virus go to hospital immediately. "The most important factor (因素) in limiting the number of H7N9 patients depends on whether the virus can spread among human beings. So far we haven't found any cases that show this kind of virus can spread from person to person," Wu said. Up to now there are no effective vaccines (疫苗) for H7N9, experts said, but using Tamiflu (克流感) may be effective in the early stages (阶段).

"Breathing masks and Banlangen (板蓝根), a traditional Chinese herbal medicine that may help fight against the virus, are in high demand. Xue Li, a sales clerk at a drugstore in Wuxi, said their Banlangen was sold out and all the masks were out of stock.

【推荐3】When I was very young, I wanted to become a veterinarian (兽医) one day, because I loved animals very much, especially dogs. But it was a pity that there was no room in my adult life for a dog. Then, last year, I could not believe that I developed cancer (癌症). I wanted to keep a dog, but I knew my illness made it impossible for me to keep one. In early September to my surprise, my doctor told me that I could keep a pet as my friend, because my immune system (免疫系统) was strong to keep a pet.

The same day I went to an animal market with my friends. When I saw a 9-week-old dog with big brown eyes, nice ears and white fur all over the body, I took him home. I called him Oscar. I’m happy these days since Oscar came into my life. My new favourite pastime is to watch him sleep, eat and run. And I have been spending more time caring about him, taking long walks with him in the park.

Now I still have the physical (身体的) examination once a week at the hospital. But my illness has taken a turn for the better with the company (陪伴) of a dog. My immune system getting stronger, my doctor tells me. Thanks to Oscar, my life has changed a lot.

【推荐2】My morning started out as usual. I snoozed（打盹）twice, took care of my three cats, hurried to complete chores while drinking some coffee, and then raced out the door for my mid-morning appointment（约会）.

After I finished my appointment, I was hungry. I stopped at a restaurant to order a burrito（墨西哥卷饼）take home and eat while working. Since it was a little before noon, there was a line. A woman, who I soon learned was Marcella, was paying at the register. She asked the woman behind her in line if she would like a drink and then asked me. We both said no, and must not have understood, because she said, “I got you.” She continued to pay for both of our meals-even though we were strangers.

I asked Marcella why she did this, and she said that someone once did something similar for her. The person asked that she mightpay it forwardsomeday and she was making good on her promise.

Before I left, she gave me a warm hug and asked only that I do an act of kindness for a stranger when I could. I arrived home, but instead of working through lunch, I sat and thought carefully and deeply about her kindness.

Marcella didn't need to pay for my lunch. But she did, and it brightened my day. Not because I got to keep my $15, but because she was kind-and did not want to receive anything in return.

As I promised her, I plan on paying her kindness forward. Maybe, just maybe, I'll make a small difference in someone else's life, and the ripple effect（连锁反应）will continue. Because that's what being human is all about-being kind, even to a stranger.
