A young fashion designer from Germany is revolutionizing high fashion by designing clothes from milk.
Domaske, 28, has developed a fabric(织物) called QMilch from high concentrations of the milk protein casein (酪蛋白). “It feels like silk and it doesn’t smell----you can wash it just like anything else,“ Domaske told Reuters. Made from all natural materials, QMilch has many health benefits, says Domaske. The amion acids （氨基酸）in the protein fight bacteria and aging, and can help regulate both blood circulation and body temperature, she says.
Domaske’s fashion label MCC is popular among people, and has now started weaving the milk fiber into its collection.
Currently MCC’s line of clothes----which feature flowing wrap dresses with modern cuts and bright patterns----are made from combinations of various fibers, including QMilch. But Domaske plans to design a collection made entirely from the milk fiber.
Milk fabric has been around since the 1930s, but was always produced in environmentally unfriendly ways that used a lot of chemicals. Unlike early forms, QMilch is made almost entirely from casein without chemicals.
“We have developed an all-natural fiber consisting of a very high concentration of casein, with a few other natural ingredients – and in only two years,” Domaske, a fo
rmer microbiology student, say.
The casein is taken from dried milk powder and then heated up in a type of meat-mincing machine（绞肉机）with other natural ingredients. The fiber comes out in threads and is then made into yarn（纱线）on a spinning machine.
Domaske says it would take about 6 liters of milk to produce an entire dress, which costs about $200 to $270. Luckily, for that kind of money, the clothes don’t come with a date when they are no longer usable----during the heating process, the molecules（分子）bond in such a way that the protein won’t break down.
Due to its anti-bacterial qualities, the fiber can also be used in medicine and makeup, and some auto companies have ever looked into using it in car seat covering.Which of the following feature of QMilch is NOT mentioned in the passage?
| A．It is beneficial to one’s health. |
| B．It feels soft and has a special smell. |
| C．It is easy to clean. |
| D．It is a man-made fiber that uses no chemicals. |

It is common to have difficulties sleeping during the day. Humans are naturally wired to sleep best at night and be awake during the day. However, modern work schedules require some people to try to accommodate the unnatural schedule of shift(轮班)work — being awake at night and sleeping during the day.
In order to make this adjustment, you need to pay special attention to your sleep environment and your preparation for sleep. If shift work is a necessary part of your work life, here are some suggestions that may help.
Arrange to sleep uninterrupted in a quiet, dark room. This means you may have to turn off or unplug your phone, hang darkening curtains on the windows or wear a sleep eye mask, and train your family and friends to leave you alone while you sleep.
Fit in a nap(小睡). When your daytime sleep period is too short, taking a short nap of less than 30 minutes just before work or on a break has been shown to improve alertness and enhance performance.
Develop and follow a sleep routine. It's best if you go to sleep and wake up at the same time every day. Try not to vary this too much at weekends. Your body likes routine.
Take extra care to make healthy choices. You may be tempted to reach for unhealthy foods or nicotine to stay awake or alcohol to try to sleep. But ultimately these choices are more harmful than helpful.
If you have tried all these things and are still having problems getting enough quality sleep during the day, talk to your doctor or a sleep specialist. Sometimes medications(药物治疗)may be helpful and safe. In other cases, there may be an underlying sleep disorder that needs to be addressed.
| A．persuade workers to have a good sleep. |
| B．advise night workers to keep healthy |
| C．encourage workers to do day work |
| D．help night workers to sleep well |
| A．A suitable amount of alcohol to help sleep. |
| B．A regular life on weekdays and weekends. |
| C．A dark room without phones to sleep in. |
| D．A break for sleeping anytime during the day. |
| A．If he suffers from a sleep disorder for the first time. |
| B．If a good sleep environment is greatly needed for him. |
| C．If he fails to get quality sleep through his own efforts. |
| D．If he has the problem of falling asleep in the daytime. |
| A．night workers need a long time to fall asleep |
| B．constant breaks at work help to improve performance |
| C．it is difficult to create a good sleep environment |
| D．night work requires people to adjust their body clocks |
When a storm is coming, most people leave the area as quickly as possible and head for safety. But there are a few people who will get into their cars and go straight to the center of the storm. These people are willing to risk being killed by floods or 100-kilometer-an-hour winds for the excitement of watching the storm close up.
“Storm chasing ” is becoming an increasingly popular hobby , especially in the Midwest of the United States, where there are frequent storms between March and July. A storm chaser begins the day by checking the Internet for the latest weather reports, and then drives up to 1,000 kilometers to where the storm will be and waits for it to develop.
Although anyone can do it , storm chasing is extremely dangerous. The power of a big storm can throw a cow into the air or destroy a whole house in seconds. Storm chasers are also often hurt in accidents caused by driving in a heavy rain. If you are a beginner, it is much safer to join a group for storm-chasing vacations during the storm season.
Even then, storm chasing is not all adventure and excitement. “Storm chasing is 95% driving,” says Daniel Lynch, who spends most of his summer storm-chasing. “Sometimes you can sit around for hours waiting for something to happen, and all you get is blue sky and a few light showers.”
However, for storm chasers, it is all worth it. “When you get close to a storm, it is the most exciting sight you will ever see in your life,” says Jasper Morley. “Every storm is an example of the power of nature, It is the greatest show on earth.”
| A．head straight for the center of the storm |
| B．get into the car for safety |
| C．wait patiently for the storm to develop |
| D．collect information about a coming storm |
| A．not to drive in a heavy rain |
| B．to do it in an organized way |
| C．not to get too close to a storm |
| D．to spend more time on it in summer |
| A．storm chasing costs a lot of money |
| B．storm chasing is worth hours of waiting |
| C．efforts in storm chasing are well paid |
| D．a storm presents the greatest show on earth |
| A．Sometimes storm chasers get nothing but disappointment |
| B．Many storm chasers get killed in the storms. |
| C．Storm chasing is becoming popular around the world. |
| D．Storm chasing is only fit for young people. |
MOOCs, an acronym（缩写）for “massive open online courses,” mark an important, possibly revolutionary, development in education．These courses are online, free of charge, and open to anyone in the world who has a laptop and an Internet connection．Moreover, they are mainly offered by elite universities like Standford, Berkeley, Harvard and Columbia．
The courses, like normal college courses, are sequenced（按顺序排好）by difficulty, enabling students to progress from beginners to the advanced．The courses cover not only a broad range of technical subjects such as math and computer science, but also courses in the social sciences and the humanities （人文学科）．
Though MOOCs are not offered for credit and degree, many students enroll in the courses for real skills or knowledge which they can put to some practical use．Some students even form online study groups, or in-person groups with students who live nearby．
The format seems superior to the traditional school class．The average quality of the lecturer is much higher, because students do not have to stick with a mediocre（平庸的） lecturer．
Besides, students can scroll back or forward—in short, they can go at their own learning speed, which they cannot do in a live lecture．And, of great importance, they do not have to travel anywhere to attend an online lecture．One can obtain a first-class American college education wherever he or she lives and however little money he or she has．
There is a problem of asking questions of the lecturer in a class of ten thousand students, but some MOOCs have solved it by allowing students to post questions online for a vote, and only the most popular questions are put to the lecturer．
In a knowledge era, lifelong learning is not confined to a traditional classroom．Of course, students enrolling in MOOCs cannot be compared with those who are in traditional universities, but we need to rethink what a “students” is．
Students in MOOCs are very clever, have work experience, and in many cases, have already developed a set of core competences．Moreover, they also offer unique international perspectives that would be the envy of any school classroom．Which of the following statements is NOT true about MOOCs?

At 4：53 pm．on January 12, United Nations aid worker Jens Kristensen was at his desk reading documents on the third floor of the Christopher Hotel, which served as UN headquarters in PortauPrince, when he felt a tremor（震颤）．Four seconds later, the earthquake hit．
“In a split second, I considered whether to run for the door or hide under my desk，” says Kristensen, 48．“The door was closed, and I thought that maybe it was too far and I would be caught under falling debris（杂物）, so I hid under the table．” A bookshelf topped onto his desk, protecting him from being crushed by rubble and trapping him in a tiny pocket．“I was confined as if in a small coffin，” he says．It was so dark, and it didn’t matter if his eyes were open or closed．He used the light from his mobile phone to see around him．He found, among other items, a jar of instant coffee．“I had no food or water, only the coffee to suck on if I needed it．”
At about 6：30 am．on January 17, an oil leak silenced the building’s generators, and Kristensen was able to hear muffled voices above where he was buried．“I thought, I was too tired to bang and shout．But then I realized, I had to take every chance．This could be one．” So he called out．Six hours later, Kristensen saw his rescuers’ faces．“It was so amazing．I felt I had received a second birthday，” he recalls．
Dehydration（脱水） and pains but with only a bruise and a scratch, Kristensen took three days to recover．The UN lost more than 90 people in Haiti．But Kristensen says that the outpouring of love helps heal the pain “The genuine happiness of people toward me here has been wonderful．You feel part of a larger family．”When the earthquake struck, Jens Kristensen decided to ________．
