Researchers with the University of Cambridge say they have the first real evidence of a new state of matter, some 40 years after it was first theorized.

Known as “quantum spin liquid(量子旋转水)”, the matter state causes normally unbreakable electrons to break into pieces called “Majorana fermions.” These fermions are an important discovery. Physicists believe the material is vital to further develop quantum computing. Computers employing Majorana femuons would be able to carry out calculations beyond the scale of modern computers quickly, they say.

Quantum spin liquid explains some of the eccentric behaviors inside magnetic(磁性的) materials. In these materials, the electrons should behave like small bar magnets, all adjusting towards magnetic north when a material is cooled. But not all magnetic materials do this—if the material contains quantum spin liquid, the electrons don’t all line up and become involved.

“Until recently, we didn’t even know what the experimental fingerprints of a quantum spin liquid would look like,” researcher Dr.Dmitry Kovrizhin says. “That created a challenge for the researchers, so they decided to employ neutron scattering(神经扫描) techniques to look for evidence of break”. What they found surprised them. The features matched nearly exactly with quantum spin liquid models theorized by physicist Phil Anderson in 1973. The results of their breakthrough were then published in the scientific journal Nature Materials on Monday.

Don’t get too excited just yet on its applications, though. Kovirzhin’s work is only the beginning and as we’ve seen with quantum computing there is a lot of work to be done. But it’s still exciting regardless.

“It’s an important step for our understanding of quantum matter,” Kovrizhin says. “It’s fun to have another new quantum state that we’ve never seen before—it presents us with new possibilities to try new things.”

Campbell Remess taught himself how to sew when he was only 9 years old. It all started three years ago, when Campbell asked his parents if they could buy Christmas presents for kids in hospital. They were touched by his kindness, but told him that buying so many toys would be too costly. He is one of nine children, and buying presents for all of them was already a pretty expensive affair for the parents.

Campbell didn’t let a simple “no” discourage him from bringing a bit of joy to kids going through tough times, so he decided to make the presents himself. It took the 9-year-old boy five hours to create his first stuffed (填充的) toy. However after three years of practice, he is now able to put one together in just an hour.

“I was blown away by the first bear,” his mother said. “Overly impressed but not surprised at his determination to teach himself.” The successful experiment only inspired Campbell Remess to become better at sewing, and challenged himself to create one stuffed toy per day and donate them to sick children struggling in the hospital. Project 365 by Campbell was born. Over the last three years, Campbell Remess has created over 800 stuffed toys for sick children.

Campbell sends his toys to children all over the world, and still visits the Royal Hobart Hospital in his home city of Hobart, Tasmania, to personally gift toy animals to sick kids there and loves to see the reaction on their faces. “They smile and some hug me. It makes their whole day better,” he says.

“Campbell is just wired really differently. He looks at sadness and tries to turn it upside down,” his mother says. “He’s not a quitter—I only see bigger and brighter things for him.”

1.Why did Campbell’s parents refuse his request?

A. They thought that was ridiculous.

B. They wished him to depend on himself.

C. They were on a tight budget.

D. They hoped he could share his things with others.

2.What desire drove Campbell to make toys for sick children?

A. Bringing happiness to them. B. Showing kindness to them.

C. Encouraging them to treasure health. D. Proving to them everyone has creativity.

3.What can we learn about Campbell from the text?

A. He is planning to set up Project 365.

B. He sends toys to those who can’t afford one.

C. He made the first toy with his mother’s help.

D. He is determined and refuses to give up.

Taking a photo of your food and posting it online is becoming more and more popular. However, not everyone thinks it’s such a good idea.

Food photos are popular on social networking sites. People often post pictures of their meals on Facebook or photo sites such as Tumblr and Instagram. Many of the pictures are of delicious-looking food from top-class restaurants. Some people even find it addictive(上瘾的). “I couldn’t get enough of it. I had to IG (instagram) every single meal,” one food poster wrote.

However, not all food photos are so attractive. There are now sites where you can post pictures of terrible-looking food. One such website is saddesklunch.com. Users send pictures of their depressing meals, which include things such as half-eaten bits of chicken and leftover pizza.

Sad Desk Lunch was created by office worker Kira Fisher in 2012. At the time, she was working as a video editor in New York. “I was starting at my rather terrible vegetable soup, which I was eating at my desk, and just thought, I can’t believe I’m eating this soup, let alone eating it alone at my desk,” she said. Other similar sites include cooksuck.com, foodporndairy.com and dimlyiitmealsforone. Tumblr.com.

Some chefs are trying to stop people photographing food in their restaurants. Gilles Goujon runs a three-star restaurant in southern France. He told news website France TV Info that every time his creations appear on social networks it “takes away the surprise, and a little bit of my intellectual property(知识产权)”.

Alexandre Gauthier is the chef at the “Grenouillere” restaurant a “no camera” logo on his menus. “Before, people took pictures of their family in the restaurant; now we take pictures of food... We tweet, we ‘like’(点赞), we respond to comments, and the dish is cold,” he explained.

Will you be taking your camera next time you eat out?

1.On which of the following websites can you probably find photos of tasty food?

A. cooksuck.com B. instagram.com

C. saddesklunch.com D. foodporndairy.com

2.What’s Gilles Goujon’s attitude towards food photography in restaurants?

A. He dislikes it. B. He supports it.

C. He is interested in it. D. He is uncertain about it.

Recently I read the Human Development Report.I couldn't help thinking about another problem why the world is facing hunger.According to the report,2400 people are dying from hunger every day;nearly 13 million in southern Africa will be worried about their food supply because of earthquakes,floods or wars.

In a word,hunger remains the biggest problem of the world today.It's strange to see that man can travel to the moon,but still doesn't know how to feed himself.You may ask,“Who steals our bread?”The first thieves should be population growth,poverty and loss of rich farmland.

In less developed areas like South Africa,the population grows faster than the crops.It is almost impossible for its government to feed so many people and provide education for them.So it is very important to control the population growth and protect their farmland in countries whose people are suffering from hunger.

According to the report,the world's food production is enough to feed everyone if it is given away well.But the problem is that the developed countries are eating food that should be given to the poor.Although they are just using their own earning,the fact is that they are coldly watching others starving away.

Luckily,some developed countries such as Netherlands,Norway and Sweden have done a lot to help those hungry people in African countries.We hope other developed countries will follow them.

1.According to the passage,which of the following cannot help make fewer people hungry?

A. Poor countries control their population growth.

B. Poor countries protect their rich farmland.

C. Rich countries produce more food to feed themselves.

D. Rich countries give some food to the poor ones.

2.The fourth paragraph mainly tells us________.

A. poor countries are cold and going to die out

B. rich countries notice the problems of the poor countries

C. rich countries are trying their best to help poor countries

D. rich countries aren't willing to help poor countries

3.According to the last sentence,the writer hopes________.

A. poor countries should learn from rich ones

B. more rich countries will help the hungry people

C. more countries will give help to Norway

D. more countries will be as rich as Sweden
