Little Tom down the street calls our dog "The keep dog". Zip is a sheep dog. But when Tom tries to say " Sheep", it comes out "keep". And in a way Tom is right. Zip is always bringing things home for us to keep! I'll tell you about some of them. Zip's first present was a shoe. It was made of green silk. We didn't know how Zip found the shoe. But after a moment, Mary, my big sister, told me the shoe had a strange smell. I nodded(点头) and held my nose. "What do you think it is?" "It smells like something for cleaning. I think someone tried to clean a spot (污点) off the shoe. Then he put it at the door to dry." Along came Zip. And good-bye shoe!" I said. "We should take it back." "We can't".said my sister. "Maybe little Tom is right," Mary said. "Maybe Zip is a keep dog!"

    According to findings of a survey by Citi and Seventeen Magazine, nearly four out of five (almost 80 percent) college students work while attending college, with the average work load of 19 hours per week. But should college students work while at college? Many factors should be considered.

    One benefit of working while in college is that it can help build your resume, regardless of whether the job is in your field, according to an article at Scholarships.com. "If you're lucky enough to find a job that closely relates to your major, you could get a leg up on the rest of your class once you graduate, because you'll have more experience in your chosen field," according to the article.

    Perhaps the most compelling reason for working while earning a degree is the money. While it's unlikely to entirely finance your education through a part-time or full-time job, you can still make quite a dent(削减)in the college bill by working.

    But some students prefer not to work while earning a degree so they can focus on getting the best grades. It's true that you'll have more time to stay at school if you don't work, provided you use that time wisely. If you feel like even 10-15 hours a week of work will hurt your grades, then perhaps you should not consider working.

    Working a part-time or full-time job can take away time from social activities, according to a You University TV article. "Trying to balance a job and your college studies, and taking a job can cut down your time to hang out with friends," according to writer Dave Potts.

    In addition to missing out on hanging out with your friends, working during college could prevent you from attending a number of campus events, such as movies on the lawn or football games. While you may be able to land a job that's flexible, it seems unlikely they'll let you choose your own schedule.

    So should students work at college? The decision should be made on a case-by-case basis. Some students can also thrive in school while working, whereas others can't.

    Generations of children grew up reading comic(漫画) books secretly, hiding out from parents and teachers who saw them as a waste of time and a risk to young minds. Comics are now gaining a new respectability at school. That is thanks to an increasingly popular and creative programme, often aimed at struggling readers, that encourages children to plot, write and draw comic books, in many cases using themes from their own lives.

    The Comic Book Project was started in 2001 by Michael Bitz at an elementary school in Queens. Since its creation, the programme, which is mainly conducted after school, has spread to more than 850 schools across the country. It has gotten a big push from the craze(狂热) among adolescents for comic book clubs and for Manga, a widly popular variety of comic originating in Japan.

    The point is not to drop a comic book on a child's desk and say “read this”. Rather, the workshops give groups of students the opportunity to collaborate(合著) on often complex stories and charac-ters that they then revise, publish and share with others in their communities.

    Teachers are finding it easier to teach writing, grammar and punctuation with material that students are fully invested in(投入). And it turns out that comic books have other built-in advantages. The pairing of visual and written plotlines that they rely on appear to be especially helpful to struggling readers. No one is suggesting that comic books should substitute for traditional books or for standard reading and composition lessons. Teachers who would once have dismissed comics out of hand are learning to exploit(利用) a style that clearly has a powerful hold on young minds. They are using what works.

    People generally tend to pick out the best-looking fruits and vegetables when shopping for produce, but Canadian supermarket chain Loblaws is attracting customers with badly-shaped and faulty produce at the price of 30% lower than normal-looking ones.

    A trial run of the ugly food line, named "Naturally Imperfect", began with only apples and tomatoes to choose from. Consumer demand has been so huge that Loblaws is going to introduce more unsightly vegetables and fruit options like onions and mushrooms. The line is available at other stores, including Real Canadian Superstore and Your Independent Grocer.

    All the produce that will be sold through Naturally Imperfect would otherwise have been used in juices, sauces, or soups, or have not been harvested at all. The director Dan Branson explained that this program benefited both food producers who would otherwise have to let abnormal harvest go to waste, and consumers who could buy fresh produce at low prices. And he was right, given how popular the line has become.

    "It really went well beyond our expectation," Branson said. "I think it really spoke to the fact that Canadians are out there really looking for some options."

    Of course, Canadians know that beauty is more than skin deep, but they also recognize that they can get the same flavor and nutritional benefits in spite of appearances. The positive response to the initial offering of apples and potatoes showed the opportunity to expand the line and offer more options at a greater price to Canadian families.

    "If you grow produce in your backyard, there will be a lot of produce that won't look as pretty as what you will see in a grocery store," said Branson. "And nature doesn't grow everything perfectly. I'd like to think if somebody were to take a No Name Naturally Imperfect apple, put right beside a No.1 apple, close their eyes and eat them, there would be no difference."

    I didn't know how to say no, and was afraid to tell people what I wanted. Instead, I got myself tangled (纠结的) in a web of obligations, anxiety, and white lies.

    The worst thing was that I didn't even realize what I was doing. I thought I knew how to say "no"—but couldn't remember the last time I had. Like a lot of people, I just wanted to be accepted, appreciated, loved—and that the only way to get those things was to put everyone else's needs before my own.

    I never seemed to have time for things I really wanted to do. I'd like to learn Spanish, write more fiction, and travel. These aren't huge, unrealistic goals. And yet, my people-pleasing ways dramatically cut into my free time to pursue these desires.

    But recently, I decided I'd had enough. As an experiment, I began standing up for myself, even at the risk of alienating (使疏远) myself from everyone and having my entire life come crashing down around me. Several days ago, a good friend asked me to go for coffee at 5 p.m. I was planning to hit the gym and then binge—watch Mad Men for the millionth time. I said, "Sorry, I've got things I want to do tonight." She said, "That's fine. Maybe another time." It was all so painfully simple that I wanted to cry.

    Saying "no" is so much easier. If someone asks me to do something I have zero interest in, I'm polite but honest. "I'm sorry, I don't think that's really for me." The words slip out my mouth faster than some other lame excuses.

    Learning how to say "no" has added several extra hours to my days, days to my weeks, and what feels like months to my years. I no longer have to back-burner my plans to help friends with their job search, or set aside a weekend to read a book draft by someone I barely know. Saying "no" has set me free.

Scientists have long thought about whether each animal species has a different language, much like different human languages that we cannot understand. Language experts agree on the fact that the way animals communicate through various calls does not fit the definition of human languages.

Animal calls are not considered a language because the calls are limited to signals related to food activities, warning about the presence of enemies and so on. They lack the characteristic of productivity that all human languages share. That is — humans create new expressions every day by combining different words to express meanings. Animal calls are fixed in their meanings, while human language goes further and includes expressions of complex ideas that do not have a limit.

However, animals do communicate. People who study humans believe that people speak with their entire bodies. To express a message, one does not always need words. Have you ever shared a private joke with your friends across the table? All you did was to give them a self-satisfied smile, Animals can communicate in much the same way as humans do. Although animals do not have the ability to speak words, they can use other methods, such as gestures, movements, calls and their sense of smell. In short, most of their communication is not related with speech.

If animals can make noises, why can't they talk? Humans and animals both have the necessary organs that produce sounds, such as lungs, throat, voice box, lips and tongue. But the differences lie in the movement and relative position of these organs that make it possible for us to speak.

When humans developed from apes, a lot of our features were improved to better shape sounds along the way. The mouth started getting smaller and the neck grew longer. All other animals, including our closest animal relatives — chimpanzees, have little similarity, which determines humans' ability to speak.
