While marathon study sessions may be unavoidable sometimes, do your best to manage your time effectively.
Reduce your workload by studying more efficiently. Before you start studying, always read your task sheet to make sure you’re focusing on the right topics. 1. This saves you time looking it up. Finally, pick out the most important information, so you can study it first.
2. Make sure you have everything you need, so you won't need to get up every few minutes to get something. Neatly place your textbooks, pens, notebook and other study materials in your study space. This way you can easily get what you need without taking an unplanned break. Plan out your study sessions in advance. Think about the time you'll need for each task, add 10% extra time for insurance, and then schedule blocks for your tasks. 3. Remember to include short breaks every hour or so.
Break up difficult tasks into smaller steps. Tasks such as “Study for History Final” or “Write Term Paper” can seem unapproachable. Instead of getting confused and upset, divide big tasks into small ones If you’re studying for a final of a course, start by looking over past tests and quizzes. 4.Smaller study tasks may also include creating outlines that summarize textbook chapters.
Do your best to space out your study sessions instead of cramming （突击）.Whenever possible, give yourself time to study a little bit at a time. It’s better to study for 3 separate 3-hour sessions instead of 1 marathon 9-hour session. 5.
A.Choose a quiet spot for studying.
B.Prepare your area before you start studying.
C.Schedule your toughest and most important tasks first.
D.Study difficult subjects first to get them out of the way.
E.Then divide the course into its units, and study one unit at a time.
F.Additionally, ask your instructor to explain any topic that confuses you.
G.Multiple shorter sessions will help you remember more information in the long run.
Around 45% of plastic waste is recycled annually in the UK and is on the increase. However, one of the problems with present plastic recycling methods is that you end up with a lower-quality plastic with worse properties （特性）than the original. This means that plastic drink bottles cannot simply be recycled into new drink bottles continuously, but instead are used for other lower-grade products like park benches.
Now, British scientists have developed a new method of chemical recycling. They use lower temperatures and more environmentally-friendly starting chemicals than previous methods to turn plastics back into their constituent chemical molecules （分子）.In this way, they can be used to make new plastics of the same quality as the original.
"Most plastic is now recycled using mechanical methods, where they are transformed into liquids before being made into something new," said a professor named Matthew Jones. "The problem is, melting plastic changes its properties and reduces the quality. Out method of chemical recycling overcomes this problem. Then plastics can be used all over again without losing any properties?"
The researchers are recycling some kinds of plastics, including plant-based PLA, a plastic used for food packaging and PET, which is used for drink bottles. So far, the technology has only been demonstrated on a small range. However, scientists are now working to produce larger quantities of starting chemicals.
"There is no single solution to the problem of plastic waste — the approach has to be a combination of reducing, reusing and recycling. Our method of chemical recycling could allow carbon to be recycled endlessly rather than digging more up from the ground in the form of fossil fuels, or letting it into the atmosphere as a greenhouse gas," said Dr. Paul McKeown from the University of Bath.
1.What is the problem with the present plastic recycling?
A.The quality of recycled plastics declines.
B.Plastic drink bottles cannot be recycled.
C.The amount of plastic waste is increasing.
D.Recycled lower-grade products sell badly.
2.How do scientists recycle plastic waste with the new method?
A.By transforming it into fuels.
B.By heating it into liquid state.
C.By keeping its original properties.
D.By changing its molecule structure.
3.What can we learn from what Dr. Paul McKeown said?
A.Fossil fuels are endless resources.
B.The plastic waste problem has no solution.
C.Recycled carbon leads to greenhouse gases.
D.The chemical recycling is environment-friendly.
4.In which part of the website can we find the text?
A.Business. B.Tech & Science.
C.Lifestyle. D.Arts & Culture
Yoga is an ancient physical and spiritual practice originating in India. The word“yoga” comes from Sanskrit （梵文）and means to join or to unite, symbolizing the union of body and mind. Today it is practiced in various forms around the world and continues to grow in popularity. Recognizing its universal appeal, the United Nations declared 21 June as the International Day of Yoga in 2014 to raise awareness worldwide of the many benefits of practicing yoga.
Yoga is an invaluable gift from an ancient tradition. It’s not just about exercise but a way to discover the sense of oneness with yourself nature and the world. There is no written record of who invented yoga. Yoga practitioners （从业者）passed down the principles to their students. The earliest written record of yoga is generally believed to have been written by Patanjali, an Indian master who lived somewhere between 2,000 and 2,500 years ago.
Various yoga types give you multiple choices. Hatha yoga is the most widely practiced type and is excellent for beginners. It is gentle with slow and smooth movements. Kundalini yoga combines a singing session besides body and mental control. Bikram yoga is practiced in a heated room. It is to loosen muscles and to sweat to clean the body and remove symptoms of disease and pain. Ashtanga yoga is taught as a difficult workout where you move quickly from one gesture to another to build strength and patience.
In recent years, the World Health Organization has urged countries to help their citizens reduce physical inactivity, which is among the top ten leading causes of death worldwide, and a key risk factor for non-communicable diseases, such as cancer and diabetes. Yoga is a proper exercise. It is known for its ability to ease stress and anxiety. It may also help reduce several risk factors for heart diseases and promote a better sleep.

Macinley Butson was just 16 years old when she first had the idea to try and protect women from more — than — necessary radiation during breast cancer treatments—and now, her invention could be a game-changer in the medical field.
Butson, whose father works in medical physics, has always been interested in science. But she only began researching the harmful side effects of radiation treatment after her father discussed his experience with ineffective cancer treatments in his work. Since Butson had also recently lost a relative to breast cancer, she felt inspired to conduct her own research on the subject. She tried to begin her medical research by consulting scientific journals, but she found their academic terms almost impossible to understand.
She then turned to the Internet to find videos that taught how to read scientific journals. As she went deeper in her research, she stumbled upon a key bit of information: copper （铜）has been shown to be effective at protecting skin from radiation. An idea hit this Australian teen as she was viewing a film on medieval wars in her 10th grade history class. When she saw the scaled （鳞片） patterns of the mail （盔甲）,she was inspired to create a wearable protective tool out of copper. She then headed back online and watched videos on how to put together tiny scales. She made her own flexible scale-mail which she now calls SMART: Scale Mail for Radiation Therapy.
When her invention was tested in a laboratory setting, it reduced surface exposure to unnecessary radiation by 75%. And now Butson is working on getting her SMART into clinical settings for use.
