When buying a backpack, there are several things you should consider. A backpack used for carrying school supplies, for example, may not need to have as many features as a backpack that is to be used for hiking or camping.
When buying a backpack，look for one that can easily be placed on your back. Many people carry their backpacks over only one shoulder.Backpacks are designed to be carried completely on your back, supported by both shoulders, in order to help evenly distribute (分配) the weight. In fact, carrying a backpack that is either too heavy or used improperly is one of the leading causes of back injuries in students.
If the backpack will be used for carrying textbooks, it must be wide enough to contain the width of the books it will carry. If the backpack is for hiking, it needs to be large enough to carry supplies such as a solar blanket and other camping things.
Another consideration when buying a backpack is the number of compartments (隔层) the backpack has. When used for hiking or camping, it's often helpful for a backpack to have several smaller compartments.
The material is also important when buying a backpack. When buying a backpack for hiking or camping, it is best to buy one that is strong enough. If you are buying a backpack for college use, it might also help prevent your books and homework from getting wet while you are walking from one building on campus to another in the rain.
A. But this is actually a mistake.
B. There are backpacks different from traditional ones.
C. It is helpful to buy a backpack with much space inside.
D. It is important to buy one that will be comfortable to carry.
E. This way, important items such as knives are easy to reach.
F. Thus, your clothing or supplies will not get damaged in bad weather.
G. The most important consideration when buying a backpack is its future use.
You must have written your research paper, your personal essay, your book review—-whatever your school class requires. You think you have provided good information in the needed number of words.{#blank#}1{#/blank#}
But is it really done? Many teachers and professional writers believe that writing is revision.{#blank#}2{#/blank#}
Revision of writing is a necessary skill for students. The classroom is a good place to practice patience, concentration and listening. There are rewards with spending time with your thoughts and really taking time to compose your ideas in an orderly and reasonable way. You should put away your paper after you have written a first version, or draft. Wait several hours, maybe overnight, before working on it more.{#blank#}3{#/blank#} Not only are you refreshed, but you're looking at things through different eyes. That's what revision literally means—to see again through different eyes.
Following a four-step process may help you with your paper. The first step in the process is invention. It includes forming many questions about your subject. It is called “question-storming”.{#blank#}4{#/blank#}Then comes the revision period. Take your time to read what you've written, to think about it, and maybe to re-shape it based on what you see now, as a kind of new person looking at it with a reader's eyeglasses rather than a writer's. The fourth step is called “publication”.{#blank#}5{#/blank#}In a sense, anytime you turn it over to another person, that's publication.
Probably, the process takes away some of the tension of writing. And worry about the quality of your writing often disappears when you share that writing.
A. Perfect writing is not possible. B. In the second step, you draft and compose a paper. C. And you feel good because your work is finished. D. This is just like returning to a job after a vacation. E. This does not mean your writing is professional publication. F. What is most important is getting your thoughts and ideas on paper. G. In other words, writing well means making needed changes and rewriting. |
Ways to protect eyes from screens
Too much screen time may cause serious eye strain(眼疲劳) and even a sharp decline of eyesight. That's a big problem a lot of people are faced with nowadays, especially those who work on a computer. The following tips may be helpful.
Get regular eye tests.
Experts recommend having a comprehensive eye exam every year to detect (探测) problems before they develop. During this test, you should tell the doctor how often you use your phone and your computer. {#blank#}1{#/blank#}Tell your doctor about it, and your eyes can be tested more accurately at that distance.
Give your eyes space
{#blank#}2{#/blank#} Studies on computer-related eye strain suggest that screens should be no closer than 40cm from your face. If this makes it hard for you to read, consider increasing the size of the text rather than moving the screen closer.
Take breaks
This may not always be practical if you're quite busy, but it's important not to stare directly at a screen for too long. {#blank#}3{#/blank#} While surveys have shown that many office workers take no more than half an hour a day away from their computer, it's recommended that you take a 15-minute break after every two hours spent at your screen.
{#blank#}4{#/blank#}
Staring at a screen continuously for hours on end may make it difficult for you to focus. To avoid this, many eye experts recommend the “20-20-20 rule” --looking away from your phone/computer screen every 20 minutes and focusing on an object at least 20 feet away for at least 20 seconds. The science behind his trick is that looking at objects at a distance relaxes the focusing muscle in the eye. {#blank#}5{#/blank#}.
A. Exercise your eyes. B. Give your eyes a chance to rest. C. Make your screen more eye-friendly D. Studies show it's an effective way to reduce tiredness. E. You should also measure the distance from your eyes to your screen at work. F. The closer your phone/computer screen is to your eyes, the harder they have to work to focus. G. Make sure that you use your phone or computer in a room where the lighting is bright enough. |
