In 1996, John Tierney suggested in the New York Times Magazine article that “recycling is garbage.” He wrote, “The money spent on recycling programs should have been spent on real social and environmental problems. Recycling programs not only increase energy use and pollution, but also cost more money than the disposal (处理) of plain old garbage. Recycling may be the most wasteful activity in modern America.”

Environmental groups were quick to express their disagreement. They wrote reports on how recycling programs in cities can reduce pollution and cost less than regular garbage pickup and disposal. Michael Shapiro, an official of the US Environmental Protection Agency(EPA), said that “recycling can be good value for money, although there's still room for improvements.”

But in 2002, New York City, a pioneer of recycling, found that its recycling program was losing money, so it stopped glass and plastic recycling. Other major cities watched closely to see how New York was dealing with its remaining program (the city never stopped paper recycling). But then it closed its last landfill (垃圾填埋地), and private companies out of New York raised prices due to the increased workload of carrying away and disposing New York's garbage. As a result, glass and plastic recycling became profitable for the city again, and New York brought the program back. According to Cecil Adams of The Chicago Reader, the lessons learned by New York are relevant everywhere. He believes that, if managed correctly, recycling programs should cost cities less than garbage disposal.

    Even though the benefits of recycling over disposal are many, keep in mind that it better serves the environment to “reduce and reuse” before recycling is even considered as a choice.

    Doing well in high school prepares students for life in college and beyond, so achieving student success is important. High school students learn valuable information from class lectures and homework, and by asking for help when it is needed. Being prepared for tests and engaging in school activities can help a student to achieve success in high school.

    Complete any homework you are assigned on time. Then, if you need help understanding a concept you will have plenty of time to get help.

    Create a study area in your home. This can be a quiet bench outside or a seating area in your room. If you like to listen to music while studying, listen to classical or relaxing music. Be sure to have plenty of lighting in the area to read your textbook or notes.

    Keep a schedule. If you have extra-curricular activities like sports or school meetings, make sure to schedule your homework and study time around them. Keeping a schedule will allow you to get better grades while they are having fun in high school.

    Eat breakfast. Having breakfast each morning before school will give you energy and brain function to pay better attention in class. Eat snacks during study sessions to keep alert and focused on your work.

    Create a study group to help fellow high school students and get help if you need it. Studying with others will help reinforce concepts and information, and if you need help there will always be someone there to help you before you get behind in your studies.

    Set up after-school hours with your teacher if you need extra tutoring. Visiting a teacher for one-on-one time before a test will help you nail down those last few concepts you need help with.

    “Don't get discouraged, Hallie,” Kathy said, comforting her with a hug. “It sounds as if you have a bit of a mystery to solve. Maybe you should do a little spying on Maya.”

    Feeling better, Hallie put on her scuba gear（潜水服）again and waited. Maya, the dolphin, had been swimming playfully, but suddenly she threw herself to the back of the tank where the filter box（过滤箱）was located. She stuck her nose down behind the box and then swam away.

    Hallie followed Maya. “What was she doing here?” she wondered. When she looked behind the box, her question was answered. She swam back and saw Maya was in front of Kathy with a comb in her mouth waiting for her treat.

    “Maya! Where did you get that?” demanded Kathy, taking the comb and throwing her a fish.

    “I know,” declared Hallie, handing Kathy a handful of items, “I followed her to the filter box and these are what I found.”

From the look on Kathy's face, Hallie knew everything was beginning to come to light.

    “Do you remember the other day you said that Maya really liked her treats?” asked Kathy.“Well, I think this was more than a training exercise for Maya. Every time you found something in the tank, that meant one less fish for Maya. She couldn't bring all the items to me at once, so she found a hiding place for them. That way you came up empty-handed, but Maya would always get her treat.”

    “Okay, Maya,” said Hallie facing the dolphin, “you win! The treats are all yours.”

    Maya dived down, and then jumped out of the water, turning herself over in midair. Shaking their heads in disbelief, Hallie and Kathy reached for the fish. Maya deserved the treat.

    We are lucky to live in a world that is full of incredible technology. Our living rooms are packed with computers, LCD TVs, video game systems, and Blue-ray players that help us enjoy the latest entertainment. Although these items bring us joy and convenience, they also create a lot of junk. Each device needs its own plug and adaptor to keep its batteries recharged, and over time these wires get tangled (缠绕在一起的). Thankfully, something has come along to help rid our homes of this mess while still supplying these devices with the power they need. It's called wireless charging and this trend is just starting.

    Wireless charging has a lot of potential for smartphones and other electronic devices. Electronic devices can absorb the electricity once they're placed on a special charging mat. There are several advantages that wireless charging offers over traditional methods. For starters, cords (电线) have a tendency to wear out with use. Wireless charging users never have to worry about buying replacement cords. Wireless charging is also far more convenient for medical implants, as patients won't need to recharge their devices through the skin using cords. In turn, this cuts down on the risks of infection. Wireless charging can also bring safety benefits, as wired charging devices that come in contact with water can increase the chances of getting an electric shock. Wireless charging gets rid of that danger completely.

    Still, there are a few drawbacks to wireless charging. The first is speed. It takes a bit longer to charge devices wirelessly than it does if the device is plugged in. The process also requires more heat, so devices tend to get a bit hotter, which could create other safety issues. Also, since devices must be left on a special pad while charging, it is harder to operate them while they are powering up. This limitation may be gotten rid of in the future, as researchers are developing transmitters (发射器) that can charge several different devices in a room without the need to connect to a charging pad. Although wireless-charging technology may be far from perfect, it seems like a step in the right direction as we move towards a less-tangled future.

    The idea that you can use humor, laughter, and play to make you healthier probably seems too simple to be true. However, it is really true and simple. The sense of humor, laughter and play plays an important part in keeping you healthy.

    Treat the blues with a sense of humor, which is closely tied to laughter. Laughter is infectious. Have you ever heard a big laugh of a young child and been able to keep yourself from smiling? When laughter is shared between people, it makes them closer to each other and increases their happiness. Smiling is the beginning of laughter and a smile is also just as infectious as laughter is. You can experience something by smiling at everyone around you, and you will feel happier just by sharing a smile, even with a stranger.

    Play is an important part of making sure that we stay healthy. We are often encouraged to make sure our children play, and are told of the benefits of being out playing. However, what we often forget is that it is just as important for old people to make play be part of their life as it's for children. Physical play is important for the old and it certainly helps prevent illness. While the studies are still in the early stages, the studies that have been done have shown that physical play certainly plays a part in preventing cognitive (认知的) falling.
