A bra (胸罩) that can be used as a gas mask. Hitting beer bottles over peopled heads. How to turn tequila(龙舌兰) into diamonds? These are just some of the themes for this year’s Ig Nobel prizes—the most unusual scientific award ceremony in the world. And the winners are...
The chemistry prize went to Javier Morales from the National University of Mexico for his research into how to make diamonds from tequila. He used a pressure container to do this.
The public health prize was awarded to Elena Bodnar of Illinois, for patenting a bra that can be changed into a pair of gas masks. “It was inspired by the Chernobyl nuclear accident," said Bodnar, who is originally from the Ukraine.
The physics prize was awarded to Katherine Whitcome at the University of Cincinnati and colleagues. They looked into the question of why pregnant women don’t fall over.
The veterinary(兽医的) medicine prize was awarded to Catherine Douglas and Peter Rowlinson of Newcastle University's school of agriculture. Their research showed that giving cows names such as Daisy increases their milk production. "It’s the highlight of my career, ” said Douglas.
"The work amused the public, but it also addressed a serious problem about the welfare of animals.”
The peace prize went to Stephan Bolliger and his colleagues from the University of Bern in Switzerland. They did experiments to discover whether it’s more painful to hit someone on the head with a full beer bottle or an empty one. “Empty beer bottles are stronger than full ones,” the researchers reported.
And the economics prize went to the officials of four Icelandic banks (Kaupthing bank, Landsbanki, Glitnir bank and Central Bank of Iceland) for demonstrating that tiny banks can be rapidly transformed into huge banks, and vice versa.
It's nice to think that this amazing research is getting the attention it deserves!
1.What prize did Javier Morales win?
A.The chemistry prize. B.The physics prize.

There are two main types of office layouts used by most companies around the world: Landscape Office and Enclosed Office. A landscape office lacks privacy, however, this office layout is more beneficial than an enclosed office for employees to improve work efficiency and productivity.
Some people might desire an undisturbed workplace. According to the survey collected from a company with the two kinds of office layouts, most of managers prefer a workplace where they can concentrate on their work and make a clear thinking. However, managers that possess their own enclosed offices might have the feeling of being distant from their clerks, which leads to high pressure. Meanwhile, employees tend to be nervous when they have conversations with their managers in an obviously hierarchical(等级制的) environment. In contrast, a landscape office makes it easier and more pleasant for employees to communicate with their managers or their colleagues; this would result in speeding up work efficiency and productivity.
Besides, greater interaction is beneficial for employees to build up friendship in a landscape office. This can be proved by the experiment of Brookes and Kaplan. They recorded the attitudes and opinions of 120 employees toward their enclosed office before they moved to the landscape office, and then after nine months they were tested again. The researchers discovered that those employees performed positive changes in group sociability. When people have better group sociability, they experience a better team work and efficient cooperation, which surely promotes work productivity.
Some opponents claim that a landscape office would lead to the decline of the value of work satisfaction and motivation from employees. However, the result from other researchers remained controversial; in their opinion there are several factors which affect job satisfaction and motivation. 600 Canadian federal government department workers who were housed at a modern landscape office and were surveyed gave both negative and positive feedback. They admitted that they felt the sense of belonging to a team or a working community, which mainly contributes to job satisfaction. Motivation is also increased by a sense of responsibility for and loyalty to a team.
Admittedly, there are some advantages that only enclosed offices possess. However, a landscape office can combine the features of the traditional enclosed office, for example, designing the independent meeting room to decrease noise from discussion. Although the benefits of a landscape office outweigh those of an enclosed office, which layout is better should be decided by the characteristics of the people and the type of work they do.
1.What is mainly talked about in the passage?
A.Colleague cooperation and its motivation.

C.Group sociability. D.Undisturbed workplace.
3.What can be inferred from the passage?
A.Enclosed office leads to individual creativity.
B.Different working styles in enclosed office is encouraged.
C.Landscape office contributes to effective conversations.
D.Frequent communication in landscape office results in high pressure.
4.What is the author’s attitude towards office layouts?

Many diseases and medical conditions are caused by things out of our control. Doctors urge us to eat healthy foods, get exercise, stop smoking and limit our alcohol intake. 1. And it is free and easy. Smile!
When we smile, the brain wiring gets altered. The chemicals that are released are more positive. Smiling is a first step in fighting physical and emotional stress and its sometimes harmful effects on human health.
The main cause of heart attacks and strokes are blockages in blood vessels (血管).2.The most common reason for these blockages is a build-up of fatty deposits on the inner walls of the arteries (大动脉). When we feel stressed or under pressure, our body releases many natural hormones (荷尔家) including adrenaline and cortisol. When we are stressed for a long period, these stress hormones are ever-present in our bodies. And that, medical researchers warn, may lead to health problems.
3. However, they claim that when people are stressed for long periods of time, they may not make the best decisions about what to eat. They may overeat, smoke or drink too much alcohol. They may not get enough exercise or sleep. And all of these can lead to health problems.
Dr. Choctkalingam says a smile may be one way to help. He tells his patients to smile 20 times an hour. To some, that might seem like a lot of smiling. Or some might even feel foolish . . . smiling for seemingly no reason. 4. It is not invasive (侵入的) like a surgical operation. It is free and it has no bad side effects.
“Once we smile, we are relaxed. This relaxation directly lowers blood pressure, improves sugar levels in the blood. 5. .”
And it just may provide a little extra protection to everyone^ heart health.
A.But a smile does not involve drugs.
B.But there is something else we can do.
C.Experts say we can control and even prevent them.
D.These prevent blood from flowing to the heart or the brain.
E.And they are the number one cause of death around the world.
F.If we are smiling, we are breaking that link between stress and health.
G.Researchers say the link between stress and heart disease is still unclear.
