（London）—If it really is what’s on the inside that counts, then a lot of thin people might be in trouble.
Some doctors now think that the internal( 内部的) fat surrounding important organs like the heart or liver could be as dangerous as the external fat which can be noticed more easily.
“Being thin doesn’t surely mean you are not fat,” said Dr Jimmy Bell at Imperial College. Since 1994, Bell and his team have scanned nearly 800 people with MRI（核磁共振） machines to create “fat maps” showing where people store fat.
According to the result, people who keep their weight through diet rather than exercise are likely to have major deposits （沉积）of internal fat, even if they are slim.
Even people with normal Body Mass Index scores can have surprising levels of fat deposits inside. Of the women, as many as 45 percent of those with normal BMI scores (20 to 25) actually had too high levels of internal fat. Among men, the percentage was nearly 60 percent.
According to Bell, people who are fat on the inside are actually on the edge of being fat. They eat too many fatty and sugary foods, but they are not eating enough to be fat. Scientists believe we naturally store fat around the belly first, but at some point, the body may start storing it elsewhere.
Doctors are unsure about the exact dangers of internal fat, but some think it has something to do with heart disease and diabetes. They want to prove that internal fat damages the body’s communication systems.
The good news is that internal fat can be easily burned off through exercise or even by improving your diet. “If you want to be healthy, there is no short cut. Exercise has to be an important part of your lifestyle,” Bell said.What is this piece of news mainly about?

If you had a strange sound in your ear, what would you do? One man in Wales who thought he had a fly in his ear called 999, the emergency services number in Britain. And so did a woman who was worried about her green potatoes. Could she make chips with them? Were they poisonous? She didn’t hesitate about calling the local ambulance service to ask. According to a recent report, more than 31,000 non-urgent calls were made to the Welsh Ambulance Service in the last year.
Inappropriate calls are a headache for health professionals everywhere. In the US, prank calls to 911 happen on a daily basis. Many callers use apps which hide their identity. But those who try to be funny shouldn’t be surprised if the police have the last laugh. One man from Colorado was arrested for making more than 1,200 prank calls, according to a report on the US television station KOAA—TV.
People who take these calls are trained to stay calm and keep a straight face, no matter how strange the call sounds. “There’s no way for us to know whether the call is real, accidental or a prank call,” said a public safety worker interviewed by the American TV channel.
The Head of Clinical Services at the Welsh Ambulance Service, Richard Lee, has a warning for prank callers. He says:“ When people misuse the service it means our precious time is being taken away from someone who really does need our help.” Indeed, these hotlines are supposed to help the seriously ill or those with a life-threatening injury. You never know, one day, the person who needs assistance could be you or someone in your family.How does the author introduce the topic of the text?
| A．By giving examples. | B．By telling a story. |
| C．By listing figures. | D．By making a comparison. |
According to the text, prank calls are usually________.
| A．meant to be helpful | B．dealt with in time |
| C．thought highly of | D．made to play tricks |
What does the underlined phrase “have the last laugh” in Paragraph 2 probably mean?
| A．win at last. | B．never find them. |
| C．laugh at them. | D．know nothing. |
What does the author intend to suggest in the text?
| A．Prank calls are usually easy to identify. |
| B．Operators feel annoyed by strange callers. |
| C．Prank calls may cause serious results. |
| D．Prank callers should be punished by law. |
Britons may like to complain a lot, but they rarely do so right now, explains BBC writer Ruth Margolis. They would rather grumble (发牢骚) afterward. This is because Britons hate to put someone out and cause any embarrassment. Margolis writes, “For instance, I’m much more comfortable just leaving that piece of raw chicken on my plate instead of complaining to restaurant staff. But beware: if this kind of thing happens when you’re dining with an American, they will most likely speak up on your behalf and not understand why you find this ashamed.”
In a BBC blog post comparing cultural differences between the UK and the US, Margolis mentions a few other things that Americans like to do that are offensive to Britons.
● Not making introductions
Margolis says most Britons dislike this approach because “talking to strangers without being introduced gives them a stomachache”. Americans rarely introduce a new friend to their friends at parties. Strangers are supposed to introduce themselves.
● “Quite” good
Using “quite” to mean “very” happens a lot in the US. But if you are invited to a dinner party in Britain, don't describe the meal as “quite good” if you want to express high praise. To Britons’ ears, “quite” detracts from the “good”: the meal was OK but could have been better.
● Money Talk
Americans can talk about money subjects for hours without feeling uncomfortable. For Britons, says Margolis, “Talking about how much we make is unthinkable — even 1ess so than discussing our feelings.”
● Over-politeness
“It’s not that I want shop assistants to be actively rude. But neither do I want to expend energy responding to someone who's been paid to ask: ‘How are you today?’” says Margolis. In the US, it is not unusual to be greeted by a perfect stranger as “honey” or “sweetie”. But Margolis says Britons find put-on friendliness, especially in stores, deeply irritating.Margolis’ dining experience in Paragraph 1 shows that_______.
| A．Britons are particular about foods |
| B．Britons are not good at complaining |
| C．Americans usually complain directly |
| D．Americans complain more than Britons |
Which of the following might Margolis agree with?
| A．Britons enjoy talking about their feelings. |
| B．Americans introduce themselves at parties. |
| C．Americans dislike talking to strangers at parties. |
| D．Britons feel happy if treated like close friends. |
The underlined phrase “detracts from” in the text probably means ____.
| A．differs greatly from | B．increases the quality of |
| C．reduces the strength of | D．draws attention away from |
What does the text mainly talk about?
| A．How to get on well with westerners. |
| B．How to start conversations with Britons. |
| C．Ruth Margolis’ tips on public behavior. |
| D．Some American habits that annoy Britons. |
China is a land of bicycles．At least it was back in 1992 when I traveled the country．Back then everyone seemed to be riding a bicycle．Millions of them，all black．Cars were rare．Yet since my arrival in Beijing last year, I’ve found the opposite is true．There are millions of cars．However, people still use their bicycles to get around．For many, it's the easiest and cheapest way to travel today．Bicycles also come in different colors—silver, green, red, blue，yellow, whatever you want．
It’s fun people biking．They rush quickly through crossroads, move skillfully through traffic，and ride even on sidewalks．Bicycles allow people the freedom to move about that cars just can’t provide．

My first ride home was orderly．To be safe, I stayed with a“pack”of bikers while cars on the streets came running swiftly out of nowhere at times．I didn't want to get hit．So I took the ride carefully．
Crossing the streets was the biggest problem. It was a lot like crossing a major highway back in the United States．The streets here were wide，so crossing took time，skill and a little bit of luck．
I finally made it home．The feeling on the bicycle was amazing. The air hitting my face and going through my hair was wonderful．I was sitting on top of the world as I passed by places and people．Biking made me feel alive．According to the author, why are bicycles still popular in China today?

Boys’schools are the perfect place to teach young men to express their emotions and involve them in activities such as art, dance and music．
Far from the traditional image of a culture of aggressive masculinity(男子气概)，the absence of girls gives boys the chance to develop without pressure to be consistent to a stereotype(传统观念),a US study says．
Boys at single-sex schools were said to be more likely to get involved in cultural and artistic activities that helped develop their abilities to express their emotions,rather than feeling they had to obey the “boy code” of hiding their emotions to be a “real man”.
The findings of the study are against the received wisdom that boys do better when taught alongside girls．
Tony Little，headmaster of Eton，warned that boys were being ignored by the British education system because it had become too focused on girls．He criticized teachers for failing to recognize that boys are actually more emotional than girls．
The research argued that boys often perform badly in mixed schools because they become discouraged when their female peers do better earlier in speaking and reading skills．
But in single-sex schools teachers can adjust lessons to boys’ learning style，letting them move around the classroom and getting them to compete in teams to prevent boredom, wrote the study’s author, Abigail James of the University of Virginia．
Teachers could encourage boys to enjoy reading and writing with “boy-focused” approaches such as themes and characters that appeal to them．Because boys generally have sharper vision，learn best through touch, and are physically more active, they need to be given “hands-on” lessons where they are allowed to walk around.” Boys in mixed schools view classical music as feminine(女性的)and prefer the modern type in which violence and sexism are major themes.” James wrote.
Single-sex education also made it less likely that boys would feel they had to give in to a stereotype that men should be “masterful and in charge” in relationships.“In mixed schools boys feel pressed to act like men before they understand themselves well enough to know what that means.” the study reported.The author believes that a single-sex school would ．
| A．force boys to hide their emotions to be “real men” |
| B．help to form masculine aggressiveness in boys |
| C．encourage boys to express their emotions more freely |
| D．naturally place emphasis on the traditional image of a man to boys |
It is commonly believed that in a mixed school boys ．
| A．perform relatively better |
| B．grow up more healthily |
| C．behave more responsibly |
| D．receive a better education |
What does Tony Little say about the British education system?
| A．It fails more boys than girls academically． |
| B．It focuses more on mixed school education． |
| C．It fails to give boys the attention they need． |
| D．It places more pressure on boys than on girls． |
According to Abigail James，one of the advantages of single-sex schools is ．
| A．teaching can be designed to promote boys’ team spirit |
| B．boys can focus on their lessons without being absent-minded |
| C．boys can choose to learn whatever they are interested in |
| D．teaching can be adapted to suit the characteristics of boys |
Our body clock, or natural body rhythm, influences our energy and alertness. Paying attention to it can help us choose the suitable time of the day when we best perform specific tasks.
The reality, however, is that most of us organize the time around work demands, school deadlines, commuting or social events. Doing whatever the body feels like doing is a luxury in today’s fast-paced modern society.
But that doesn’t mean it isn’t worth trying. Obeying our body clock has significant health benefits. Disrupting our natural body rhythm, on the other hand, has been linked to problems such as depression, obesity, or headache, says Steve Key, a biology professor.
When the body clock can synchronize (使…同步) the rhythms of its natural processes, it “gives us an advantage in daily life”, says Key.
According to him, when it comes to cognitive (认知的) work, most adults perform best in the late morning. As our body temperature starts to rise just before awakening in the morning and continues to increase until midday, our memory, alertness and concentration gradually improve.
However, he adds, our ability to concentrate typically starts to decrease soon thereafter. Most of us are more easily distracted (分心) between noon and 4 pm.
Alertness also tends to fall after eating a meal and sleepiness tends to peak around 2 pm, making that a good time for a nap.
Surprisingly, tiredness may increase our creative powers. For most adults, problems that require open-ended thinking are often best dealt with in the evening when they are tired, according to a study in the journal Thinking & Reasoning.
When choosing a time of the day to exercise, paying attention to your body clock can improve results. Physical performance is usually best from about 3 to 6 pm, says Michael Smolensky, a professor of biomedical engineering.
Of course, not everyone’s body clock is the same, making it even harder to synchronize natural rhythms with daily plans.If we know our natural body rhythm well, we can ______.
| A．find out the suitable time to do specific tasks |
| B．organize our time around work demands |
| C．do whatever our body feels like doing |
| D．be sure to be healthy |
Which of the following is NOT true?
| A．Our alertness is influenced by our natural body rhythm. |
| B．Doing whatever your body feels like is very difficult in our modern society. |
| C．Obeying our body clock is good for our health. |
| D．Disrupting our natural body rhythm can lead to obesity. |
Inspiration to solve a difficult problem will most probably come to us______.
| A．when we get up in the morning |
| B．when we are tired in the evening |
| C．when we are full of energy in the late morning |
| D．when we are asleep at night |
Which of the following can be the suitable title for the passage?
| A．What is natural body rhythm? |
| B．Natural body rhythm is good for us. |
| C．natural body rhythm and health |
| D．The latest research about natural body rhythm. |
