Here are six steps to better studying.

Pay attention in class

    Do you have trouble paying attention in class? Are you sitting next to a loud person? Tell your teacher or parents about any problem that is preventing you from paying attention.

Take good notes

    Write down facts that your teacher mentions or writes on the board. Try to use good handwriting so you can read your notes later. It's a good idea to keep your notes organized by subject.

Plan ahead for tests and projects

    Waiting until Thursday night to study for Friday's test will make it hard to do your best. One of the best ways to make sure that doesn't happen is to plan ahead. Write down your test dates. You can then plan how much to do after school each day, and how much time to spend on each topic.

Break it up

    When there's a lot to study, it can help to break things into several parts. Let's say you have a spelling test on 20 words. Instead of thinking about all of the words at once, try breaking them down into five-word groups and work on one or two different groups each night.

Ask for help

    You can't study effectively if you don't understand the material. Be sure to ask your teacher for help. If you're at home when the confusion occurs, your mom or dad might be able to help.

Sleep tight

    So the test is tomorrow and you've followed your study plan—but suddenly you can't remember anything! Don't panic. Your brain needs time to digest all the information you've given it. Try to get a good night's sleep and you'll be surprised by what comes back to you in the morning.

    It's generally believed that people act the way they do because of their personalities and attitudes.They recycle their garbage because they care about the environment.They pay $5 for a caramel brulee latte because they like expensive coffee drinks.

    It's undeniable that behavior comes from our inner dispositions（性情）,but in many instances we also draw inferences about who we are,as suggested by the social psychologist Daryl Bern,by observing our own behavior.We can be strangers to ourselves.If we knew our own minds,why would we need to guess what our preferences are from our behavior?If our minds were an open book,we would know exactly how much we care about the environment or like lattes.Actually,we often need to look to our behavior to figure out who we are.

    Moreover,we don't just use our behavior to learn about our particular types of character—we infer characters that weren't there before.Our behavior is often shaped by little pressures around us,which we fail to recognize.Maybe we recycle because our wives and neighbors would disapprove if we didn't.Maybe we buy lattes in order to impress the people around us.We should not mistakenly believe that we always behave as a result of some inner disposition.

    Whatever pressures there can be or inferences one can make,people become what they do,though it may not be in compliance（符合）with their true desires.Therefore,we should all bear in mind Kurt Vonnegut's advice:"We are what we pretend to be,so we must be careful about what we pretend to be."

    China officially informed the World Trade Organization on Tuesday that it will ban the import of 24 different types of solid waste by the end of this year as part of a campaign to deal with environmental pollution and protect people's health.

    In response to growing public concerns over the potential environmental and health danger caused by the increasing amounts of solid waste imported into the country for recycling and treatment, China passed a special law in 1995 to control imports of waste materials, such as plastics, slag from steelmaking, unsorted scrap paper and discarded textile materials.

    A year later, the country published a list for solid waste imports and began implementing a permit system to control the import volumes and types of waste imported.

    However, due to the lack of effective supervision（监管）and the failure of relevant departments to fulfill their duties, solid waste imports have not been effectively controlled.

    So far, China is the world's largest importer of solid waste. According to the Ministry of Environmental Protection, China imported 7.3 million metric tons of plastic waste worth $3.7 billion in 2016, accounting for 56 percent of global imports of solid waste.

    Correct recycling of solid waste materials is an important part of the global economy, and moderate imports of scrap plastic, scrap paper and scrap rubber products, such as vehicle tires, can to some extent, make up for China's shortage of various raw materials.

    However, the lack of supervision has resulted in the country's severe soil and environmental worsening.

    Given that China's continuing efforts to push for industrial transformation and upgrading have resulted in a noticeable decline in the demand for the materials recycled from solid waste imports. It is right for the country to restrict such imports for the sake of the environment and public health, and to better adapt to the changed industrial structure.

    Oxford and Cambridge have now decided to remove the words CAN'T and IMPOSSIBLE from their dictionary. Jessica Cox, 25, a girl born without arms, stands inside an aircraft. The girl from Tucson, Arizona got the Sport Pilot certificate lately and became the first pilot licensed to fly using only her feet. Jessica Cox of Tucson was born without arms, but that has only stopped her from doing one thing: using the word "can't".

    Her latest flight into the seemingly impossible is becoming the first pilot licensed to fly using only her feet.

    With one foot manning the controls and the other delicately guiding the steering column, Cox, 25, soared to achieve a Sport Pilot certificate. Her certificate qualifies her to fly a light-sport aircraft to altitudes of 10,000 feet.

    "She's a good pilot. She's rock solid," said Parrish Traweek, 42, the flying instructor at San Manuel's Ray Blair Airport. Parrish Traweek runs PC Aircraft Maintenance and Flight Services and has trained many pilots, some of whom didn't come close to Cox's abilities.

    "When she came up here driving a car," Traweek recalled, "I knew she'd have no problem flying a plane."

    Doctors never learned why she was born without arms, but she figured out early on that she didn't want to use prosthetic devices. So, the next time you are ready to tell yourself, "I can't possibly..." remember this amazing young woman and change your vocabulary.

Foldable phones are once again facing questions about their durability(耐久性).The Galaxy Z Flip and the Motorola Razr are now both available to buy in the US-but early reports suggest the screens are easily damaged.

One media published photos of two layers of the Razr's display separating, affecting the touch screen. The Galaxy flip, meanwhile, boasts(自夸)a "flexible glass" display—but tests appear to show it scratching(刮擦)as easily as plastic.

In a statement, Samsung said the display had a protective layer, and had undergone extensive testing. "While the display does bend, it should be handled with care, "it said.

The Z Flip's "pretty thin glass" is one of Samsung's primary marketing messages for the new phone. But a durability test conducted by popular Zack Nelson, a regular buyer, suggested it was no more durable than soft plastic screen, and could even be dented(痕)by fingernail.

Nelson said Samsung's screen scratched exactly how plastic screen would react. "I don't know what material this is, but Samsung definitely shouldn't be calling it glass," he said. He found that the screen of the Motorola Razr scratched as easily but it is not marketed as "glass".

The Motorola Razr was put on sale 13 days ago in the US, but Raymond Wong, an editor says the flexible screen on his handset has already broken. The upper layer of the Razr's screen separated from the bottom, creating "a giant horizontal air bubble" for no apparent reason. He wrote that the fault appeared after 45-minute train ride during which the phone was in his pocket. The screen was completely warped from hinge-to-hinge with the top layer raised like a poorly applied screen protector. But Mr. Wong said that apart from the visual problem, the damage has affected the responsiveness of the touchscreen.
