Anger and other strong emotions (情感) can probably cause deadly heart beats in certain weak people，the US researchers said on Monday.
Earlier studies have shown that earthquake，war or even the loss of a World Cup Soccer game can increase chances of death from sudden cardiac arrest，in which the heart stops passing blood.
“It’s certainly been shown in all different ways that when you put people under pressure，sudden death will increase，” said Dr.Rachel Lampert of Yale University in New Haven，Connecticut.
“Our study starts to look at how this really has an effect on the electrical system of the heart，” Lampert said.
She and her assistants studied 62 patients with heart disease and ICDs that can discover dangerous heart beats and send an electrical shock to bring a normal heart beat back.
Patients in the study took part in an exercise in which they told a recent angry period while Lampert’s team did a test called TWave Alternant that measures electrical instability(不稳定性) in the heart.
Lampert said the team on purpose asked questions to get people to experience the angry period again.“We found in the lab that yes，anger did increase this electrical instability in these patients，” she said.
Next，they followed patients for three years to see which patients later had a cardiac arrest and needed a shock from their ICDs.“The people who had the highest anger were 10 times more likely than everyone else to have cardiac arrest，” she said.
Lampert said the study suggests that anger can be deadly，at least for people who are already weak to this type of electrical disorder in the heart.From the passage we know cardiac arrest refers to ________.
| A．someone who will be caught if he does something wrong |
| B．some place where you can show all your feelings |
| C．some disease that can kill people instantly |
| D．something used by patients in hospital |

| D．hunger |
What did Lampert use to measure electrical instability of patients’ heart?
| A．ICD and TWave Alternant test. |
| B．ICD and Cardic arrest. |
| C．Cardiac arrest. |
| D．The passage doesn’t tell us. |
The passage is mainly about ________.
| A．new findings for heart disease |
| B．that anger really can kill a person |
| C．a new test of measuring heart blood |
| D．a study showing danger of heart beats |
Exercise is an important part of a healthy life. It reduces your risk of heart attack and is a good way to control body weight. It is also something you can do with other people, which can be great fun. So, it is important to find time to exercise and be healthier. As well as making time to exercises, another way is to build it into the natural rhythm (节奏) of your day.
· Go for a walk on your lunch break.
Try to find at least three different ways and change them throughout the week. It
might even be possible to find a place to walk inside, for those bad weather days.
· Talk to your employers about improving health at work.
Encourage your workers to cycle to and from work. You might also be able to
encourage them to set up a gymnasium. Sell the idea by pointing out that doing so
will improve productivity (生产率), and make workers happy.
· If you are a student.
Go for walks with friends to talk about your studies. Spend some time in the learning
resource centre reading about sport, exercise and health. The more you know, the
more choices you will have about how to be physically active. Most colleges have
sport and exercise programs that students can take part in. Find out which activities
are being held, and try those you think you might enjoy.
Workers are advised to cycle to and from work to ________.
| A．make themselves realize the importance of health |
| B．work better and bring pleasure to themselves |
| C．make themselves become much stronger |
| D．reduce the time spent in walking to work |
When a student wants to do exercise at school, he or she had better ________.
| A．take part in all the exercise programs |
| B．have sports with friends or classmates |
| C．choose the one that he or she likes |
| D．choose the same one all the time |
We can learn from the passage that ________.
| A．walk is most suitable for those who work indoors |
| B．one who knows more about health will be healthier |
| C．exercising with others will be better for one’s health |
| D．combining exercise with daily work can save time to keep healthy |
An early invention by Albert Einstein has been rebuilt by scientists at Oxford University. They are trying to develop an environmentally friendly refrigerator that runs without electricity.
We all know that modern fridges cause damage to the environment. They work by using a kind of man-made greenhouse gas called Freon (氟里昂), which is far more damaging than carbon dioxide.
Now Malcolm McCulloch, an electrical engineer at Oxford, is leading a three-year project to develop appliances that can be used in places without electricity.
His team has completed a prototype (样机) of a fridge patented in 1930 by Einstein. It used only pressurized gases to keep things cold. The design was partly used in the first refrigerators, but the technology was dropped when more efficient compressors (压缩机) became popular in the 1950s. That meant a switch to using Freon.
Einstein's idea uses butane (丁烷) and water and takes advantage of the fact that liquids boil at lower temperatures, when the air pressure around them is lower.
"If you go to the top of Mount Qomolangma, water boils at a much lower temperature than it does when you're at sea level and that's because the pressure is much lower up there," said McCulloch.At one side is the evaporator (蒸发器), a bottle that contains liquid butane. "If you introduce a new vapor above the butane, the liquid boiling temperature decreases and, as it boils off, it takes energy from the surroundings to do so," says McCulloch. "That's what makes it cold."
The gas fridges based on Einstein's design were replaced by Freon-compressor fridges partly because Einstein's design was not very efficient. But McCulloch thinks that by changing the design and replacing the types of gases used it will be possible to quadruple (翻两番) the efficiency.
However, McCulloch's fridge is still in its early stages. "It's very much a prototype," he said. "Give us another month and we'll have it working."． According to the passage, an early invention by Albert Einstein _______.
| A．has been rediscovered because it costs much less and works more efficiently |

| D．show you how Einstein's fridge works |
A latest national survey has found that over half of China's netizens are suffering from various mental problems although some 62 percent of them claim at the same time that they are happy on the whole anyway.
This is the result of China's first White Paper on Netizens' Health Conditions issued on Wednesday by 39.net, China's largest authoritative website on health sciences. It is the first most comprehensive health survey on netizens' health situation ever conducted in China in ten years' time. The white paper came out after two months of online and offline research that involved over 150 thousand netizens, covering topics and questions on health knowledge, mental situation, sense of health, and living habits.
According to the white paper, more than 70 percent of China's netizens say they are suffering from mental problems such as bad memory, anxiety, depression, and a lack of confidence. And a similar 72 percent of them also say they are often suffering from diseases like insomnia, dizziness, joint degeneration and achings. Meanwhile, another 53 percent of netizens believe that white collar employees who have bigger work pressures are more likely to catch mental problems.
The white paper adds, doing almost no sports and spending long time surfing online lead to the above mentioned health problems among netizens. Only 9 percent of netizens take up sports on weekends while over 40 percent stay home, surfing. And only 16 percent netizens can assure more than eight hours' sleeping daily.

If you look up the word “create” in the dictionary , you will find it means “to bring into being, to cause to exist something each of us does daily”．

A second part of creativity is an ability to see relationships among things．If we believe the expression, “There is nothing new under the sun, the creativity is remaking or recombining（重组） the old in new ways．”For example, we might do this by finding a more effective way to study or a better way to arrange our furniture, or we might make a new combination of camera lenses and filters to create an unusual photograph．
A third part of creativity is the courage and drive to make use of our new ideas, to ask for them to achieve some new results．To think up a new idea is one thing; to put the idea to work is another．
