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.”

1.What can we learn about “Majorana fermion” according to Paragraph 2?

A. It is an important discovery 40 years ago.

B. It is a surprising theory raised by Phil Anderson.

C. It is a key piece in developing quantum computer.

As is known, some students have breakfast regularly. Therefore, others don’t, or even skip it. Among of the students who have breakfast every day, only a few have a balanced diet which includes breads, milk and eggs. There is several reasons. First of all, many students don’t know an importance of breakfast. Besides, many parents have limited knowledge about that a balanced diet is. Finally, teachers give students too much tasks, so they have no time have breakfast. In a word, every student should had breakfast regularly. The more balanced diet one has, the healthy he will be!

Group exercise is one of the most effective ways to improve physical fitness and sustain(保持) a healthy lifestyle. Group exercise is challenging, yet fun and empowering! Of course everyone knows that exercise is good for the body. However, studies have shown that when exercise is performed in groups, it's not only great for improving physical health but for psychological health. It's an opportunity to be social, release endorphins（内啡肽）, and improve your strength. Additionally, group exercise creates a community feel and the shared common goal motivates participants to work hard. The instrumental support of taking on a fitness journey with others proves more effective than going to the gym alone.

Another beneficial aspect of group exercise is the informational support participants receive from the instructor. Many people fear the gym because they feel lost and don't want to embarrass themselves. If you feel you can relate, then group training is an even better option for you. It's a great opportunity to learn more about fitness through the clear instruction and supervision (监管) of a fitness instructor. If you're tired of wandering around the gym wasting time and becoming bored, you can attend an upbeat group fitness class that'll keep your workout on track. Don't let fitness frighten you!

If you're serious about wanting to live a healthy lifestyle, it's extremely important to surround yourself with people who'll provide you with the proper emotional support. I wouldn't scold anyone for deciding to party on weekends and in turn I wouldn't expect anyone to give offence to me for focusing on my health. Surround yourself with people who uplift, encourage and understand you! Make fitness even more fun by trying something new or any group fitness class, with a friend. Plan to go for a jog together. Then try a fun healthy restaurant or fresh juice bar! Fitness can be both fun and social!

Surrounding yourself with people who'll provide you with respect support can be very beneficial while working towards reaching health and fitness goals. First, decide to do it for yourself and work towards staying positive. Then make sure the people you surround yourself with are supportive. Don't let negativity ruin your motivation.

Love to sink into your chairs and relax when you get to school? Then you will not be happy to hear that schools all over the world are seriously considering exchanging traditional desks for ones with no seats at all — Yes, that means you will be encouraged to stand through those already too long math and science lessons! Why would anyone even think of putting kids to such cruelty? Experts say it improves their health and helps fight obesity. While that may seem a little far-fetched (牵强的) the officials at the few schools around the world seem to agree.

Among them are educators from the College Station Independent School District in Texas, who recently completed a week-long experiment involving 480 students across three elementary schools. The 374 kids that agreed to participate in the study were provided a device that helped record step count and calorie consumption over the entire period.

All 25 teachers involved in the study reported that students appeared to be more alert and concentrate better, when allowed to stand. The one thing that did surprise the researchers was that younger kids were more willing to stay standing than kids in higher grades. They believe this may have something to do with the fact that after years of being asked to “sit still”, older kids have a harder time adjusting to this unexpected freedom.

American schools are not the only ones reporting success with stand-up desks. Four Catholic schools in Perth, Australia, which have been testing them since October 2013, have seen similar results. In May 2014, Grove House Primary School in Bradford, West Yorkshire, became Europe’s first test one, with a seven-week trial that involved the use of desks made by Ergotron in their fifth-grade classrooms. While official results are not out yet, early reactions from both teachers and students, have been extremely encouraging.

The findings of these studies and others done previously, all seem to mean that allowing kids to move around in classrooms is a win-win for students and teachers — it helps kids get healthier and provides educators with a more engaged audience.

1.According to the first paragraph, what may make the students at school unhappy is that ________.

A. they have to exchange desks with each other

B. they have to exchange traditional desks for ones with no seats

C. there are no seats for them to sit in class

D. the officials show no sympathy to them at all

A. they are cleverer than younger students

B. they are easily tired of standing long

C. they have formed the habit of sitting

D. they do badly in class while standing

3.What is most likely to be the result of the seven-week trial?

A. The standing desks can’t be used at all.

B. It is good for students to use stand-up desks.

C. More tests should be done in other schools.

D. The students are different in personality.

4.Why do the teachers like the standing desks?

A. Because the educators can draw the students’ attention.

B. Because the teachers can keep the students healthy.

C. Because the students can have a walk in the classroom.

D. Because the standing desks can keep the students concentrated.

Ways to Free Your Mind When You’re Feeling Stuck

Have you ever felt like you were racing around in circles without making much forward progress? If you’re stuck and you don’t know how to rise, don’t look outside yourself. Look below. 1.

Go back to what’s important

When we get stuck, it can be extremely useful to come back to these three things: core values, beliefs and goals. Why? 2.

Embrace the natural pathways

When you get stuck, there’s no need to go back to the drawing board. Ask the people around you about the systems that are working for them, read insightful books and blog articles, and use the same methods and pathways that others have used to get unstuck. 4.

Relocate yourself to an inspiring environment

5. You can go for a walk in a nearby park. You can come out of the office for a cup of coffee. Or if you are at home, you can simply go to a different room in the house. Whether it’s urban spaces, parks, libraries, museums or even our own backyards, there are plenty of available sources that we can draw inspiration and strength from.
