Snow falls in the Earth's extreme North and South throughout the year. However, the heaviest snowfalls have been reported in the mountains of other areas during winter. Snow is even known to fall near the Equator (赤道), but only on the highest mountains.

    Snow contains much less water than rain, but much of the water the world uses comes from snow. {#blank#}1{#/blank#} In the western United States, mountain snow provides up to seventy-five percent of all surface water supplies.

    Snowfall helps to protect plants and some wild animals from winter weather. Fresh snow is made largely of air trapped among the snow crystals (晶体). Because the air has trouble moving, the movement of heat is limited. {#blank#}2{#/blank#} The surface of the snow takes in, or absorbs, sound waves. As snow grows older or if there have been strong winds, it can become hard and flat. Then, the snow's surface will help to send back sound waves.

    {#blank#}3{#/blank#} It is responsible for the deaths of hundreds of people. Many people die in traffic accidents on roads covered with snow and ice or from being seriously stuck in the winter storm. {#blank#}4{#/blank#}.

    People may not be able to avoid living in areas where it snows often. However, they can avoid becoming victims of snowstorms. People should stop driving and stay at home until the storm has passed. People living in these areas should carry emergency supplies in their vehicle. {#blank#}5{#/blank#}

    When was the last time you read a book or a magazine article? Do your everyday reading habits centre around updates on the Internet? In case you are one of countless individuals who don't make a habit of reading you may be passing up a great chance: Reading has a number of advantages and only a couple of advantages of reading are recorded below.

    Everything you read fills your head with new bits of information and you never know when it might be useful to you. The more knowledge you have, the better-equipped you are to overcome any challenge you'll ever face. Besides, here's a bit of food for thought：Should you ever find yourself in a terrible situation, remember that although you might lose everything else — your job, your possessions, your money, even your health — knowledge can never be taken from you.

    At the same time, the more you read, the more words you gain, and they'll surely make their way into your everyday vocabulary. Being able to express your ideas clearly in words is of great help and knowing that you can speak to higher-ranking people with self-confidence can be a great encouragement to your self-esteem（自尊）. Reading books is also important for learning new languages, as non-native speakers gain exposure to words used in context, which will improve their own speaking and writing fluency.

    When you read a book, you have to remember a lot of characters, their backgrounds, ambitions, history as well as the various plots(各种各样的情节) through every story. That's a fair bit to remember, but brains are wonderful things and can remember these things with ease. Amazingly enough, whenever you remember something new, new synapses(神经元的突触) are formed and existing ones are strengthened. How cool that is!

    No matter how much stress you have at work, in your personal relationships, or countless other issues faced in daily life, it all just slips away when you lose yourself in a great story. A well-written novel can transport you to other fields while an interesting article will distract(使分心） you and keep you in the present moment, letting stress away and allowing you to relax.

    Homework

    Do arithmetic problems 15 through 25. State the different forms of the verbs on page 50 of your French workbook. Read pages 12 through 20 of the Shakespeare play, and don't forget to fill in the missing chemical symbols on the worksheet.

    Sound like a list of your homework for the next few nights － or maybe even just for tonight? {#blank#}1{#/blank#}It's your teachers' way of evaluating how much you understand what's going on in class. And it helps strengthen important concepts.

    {#blank#}2{#/blank#} It's inviting to start with the easy things to get them out of the way. However, you'll have the most energy and focus when you begin, so it's best to use this mental power on the subjects that are most challenging. Later, when you're more tired, you can focus on the simpler things. If you get stuck on a problem, try to figure it out as well as you can － but don't spend too much time on it because this can mess up your homework schedule for the rest of the night.{#blank#}3{#/blank#}But don't pick someone whom you'll be up all night chatting with, or you'll never get it done!

    Most people's attention spans aren't very long, so take some breaks while doing your homework. Sitting for too long without relaxing will make you less productive than if you stop every so often. Taking a 15-minute break every hour is a good idea for most people.{#blank#}4{#/blank#}

    Once your homework is done, you can check over it if you have extra time. Be sure to put it safely away in your backpack － there's nothing worse than having a completed assignment that you can't find the next morning or that gets ruined by a careless brother or sister.{#blank#}5{#/blank#}Now you're free to hang out.

A. Homework is a major part of going to school.

B. Luckily, you can do a few things to do less homework.

C. When you start your homework, deal with the hardest tasks first.

D. But if you're really concentrating, wait until it's a good time to stop.

E. If you need to, ask an adult for help or call or email a classmate for advice.

F. And no teacher still believes that "chewed by the dog" line － even when it's true!

G. In conclusion, no one is expected to stay long, and people have very different learning styles.

    We eat in our cars, at our desks, on the go, and in front of the TV. We eat take-out, packaged and prepared meals. Why? Because it fits our not-enough-time-in-the-day lifestyles{#blank#}1{#/blank#} Well, I'm certainly not the first one to think it—or say it—but we all need to slow down.

    Consumer trends around the globe show that over the past three decades people are purchasing more prepared foods at the grocery and eating out more than ever before. It's predicted that we'll spend more at restaurants in the coming years{#blank#}2{#/blank#}However, we're getting less healthy.

    While debates can be seen indifferent media over the food industry's contribution to our growing waistlines and our health problems, the bottom line is this{#blank#}3{#/blank#}We can choose to eat a fast-food lunch on the go. We can throw a frozen meal in the microwave and call it dinner. We can eat without thinking, in front of the tube, at our computers, and while driving a car.

    {#blank#}4{#/blank#}Studies have shown meaningful links between family meals and kids' mental and physical well-being. Eating sensibly doesn't take much time or money, but it does require you to make a conscious decision to do so. Wrapped in endless work, appointments and social activities, we often fail to enjoy a relaxing meal with our families.

    While it can be a challenge to always put healthy eating first, just do your best. Remember that the food you eat has a more significant impact on your health, weight and well-being than almost any other activity you do.{#blank#}5{#/blank#} Every meal made at home—even just once or twice a week—is a step closer to a healthier body and as lower food lifestyle.

A. Our food matches our lives.

B. Treat it with the importance that it deserves, but start small.

C. We're consuming an increasing number of calories.

D. Lunch is the biggest calorie intake when it comes to eating out.

E. Purchase food locally and skip as many packaged items as you can.

F. What we eat, where we eat and how we eat are all under our control.

G. We can devote an hour of the day to enjoying a meal with our families.

    On an average day most of us check our smartphones 47 times, and this habit clouds our judgment on what information to select and store, which might explain why it's time we should do things about the information we take in to form memories.

    As simple as it sounds, the repetition of tasks-reading, or saying words over and over — continues to be the best method for transforming short-term memories into long-term ones. To do that, we have to retrain our minds to focus on one task at a time. Sadly, most turn a blind eye to this formula because we believe we're productive. New connections are made in your brain when you learn, so to remember what you learn, do what you probably did in your youth: Repeat words, thoughts and ideas over and over until you get them right.

    Also, spaced repetition might be the best way. Quickly pushing facts into our brains leads us to forget them in the long term. When you review knowledge and practice it often, it sticks, a research has shown. So if you can include what you're trying to remember into daily life, ideally over time, your chances of keeping it significantly improve. But once you stop reviewing that knowledge, the retention (保留) drops greatly. To get past it, space out your repetition over a few days and test the effect yourself. But be careful: find a healthy interval that works. This is a good way to effectively start tackling a new language.

    Sometimes, memory and focus usually go hand-in-hand. Dr. Cowan suggests rearranging our office setup as one way to improve focus. "The rebirth of the open workplace cannot be helping stay on task, "Dr. Cowan said. Referring to work spaces without desks, physical barriers and privacy, but with a lot of playthings.

    Multiple studies have found that procrastination (拖延) leads to stress and completely kills focus. Stop engaging in useless tasks like surfing the web and just handle whatever it is you need to work on. Then watch your focus increase quickly and your memory improve.

    Memory is very cue (提示) dependent, "Mr. Schacter, a psychologist, said, referring to. Something he calls absent-minded memory failure. "Most say it could never happen to me, but it's a very long list of responsible people that it has happened to. When you don't have that cue, you can forget almost everything. "

    A simple way around that is to set reminders. Even better, combine a few of these techniques: Write your reminder on a post-it and put it on your desk so you're forced to repeatedly look at it over a long period, including the practice of spaced repetition.
