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#}

A. These include food, emergency medical supplies, and extra clothing to stay warm and dry.

B. Snow also influences the movement of sound waves.

C. Melting snow provides water for rivers, electric power stations and agricultural crops.

D. Mountain snowfall is heavier than that in the South and the North Poles.

E. In many places, streets were blocked; houses fell down and supplies were short.

F. Others die from heart attacks caused by too much physical activity out in the cold.

G. Snow may be beautiful, but it can be deadly.

    Worry problems are everywhere in our daily life. How to solve them? The answer is that we must equip ourselves to handle different kinds of worries by learning the three basic steps of problem analysis. The three steps are:

Get the facts

    Why is it so important to get the facts? Unless you have the facts, you can't possibly attempt to solve your problem intelligently. Without the facts, all you can do is wondering around in confusion{#blank#}1{#/blank#}When you are worried, your emotions are riding high. But here are two ideas that can help you see the facts in a clear and objective way.

    When trying to get the facts, you can pretend that you are collecting this information not for yourself but for some other person. This will help you to take a cold and fair view of the evidence. You can also pretend that you are a lawyer preparing to agree{#blank#}2{#/blank#}You will generally find the truth lies somewhere in between.

Analyze the facts

    {#blank#}3{#/blank#}And write out all the various steps you could take and then the probable consequences(后果) of each step. For example, what am I worrying about? What can I do about it? Here is what I'm going to do about it. After carefully weighing all the facts, you can calmly come to a decision.

{#blank#}4{#/blank#}

Unless you take your action, all you face—finding and analyzing—is a waste of energy. How can you break the worry habit before it breaks you? Crowd worry out of your mind by keeping busy.{#blank#}5{#/blank#} Accept what can't be avoided. If you know a situation is beyond your power, say to yourself: “ It is so; it can't be otherwise.” Don't permit little things to ruin your happiness. Try to develop a mental attitude that will bring you peace and happiness.

A. Act on that decision

B. It is not an easy job to get facts.

C. Decide how much anxiety a thing may be worth

D. Plenty of action is one of the best ways to cure worry.

E. There comes a time when you must decide and never look back

F. Try to get all the facts both on your side and the other side of the case

G. Whenever you are worried, write down the questions that make you worry.

    Are you planning to go to university? {#blank#}1{#/blank#}Perhaps you will be choosing the classes you want to take, finding accommodation and enrolling in other activities. However, if you go to university in Chile there is something extra you must do before you can begin.

    An essential part of starting university in Chile is the “mechoneo”{#blank#}2{#/blank#} Students beginning their first year at university are “welcomed” by the older university students. They are taken from their classrooms on an unknown day and blindfolded. The older students tear their clothes, cut their hair, and cover them in raw eggs and other disgusting things.

    {#blank#}3{#/blank#} This will be based on how well the students do the activities, and many students try very hard as they want to be the king or queen of the year. The older students then take away everything of the younger students and tell them they must go out onto the street and ask people for money. They will need to bring back a certain amount of money in order to be given their things back.{#blank#}4{#/blank#}

    During March it is common to see new university students all around town wearing ripped, dirty clothes and covered in paint and mess. But the “mechoneo” is increasingly a source of dispute and debate. Some students see it as an important tradition and a unique experience that help new arrivals get to know everyone.{#blank#}5{#/blank#} There have been campaigns to ban or soften it in favour of more “positive welcomes'', and student organizations in some universities have voted to end the “mechoneo” completely.

A. It is an ancient university tradition here.

B. The younger students are forced to do games in dirty places.

C. The “queen mechona” and “king mechon” are chosen that day.

D. They have to do games and take up challenges for a whole day.

E. But others find it abusive, like a form of bullying.

F. What do you think you need to do in the first few weeks?

G. The money is then used to have a massive welcome party at night-time.

    If you want to keep fit, please refer to the following;

    Move More

    Make it a rule to find ways to move your body. {#blank#}1{#/blank#} Climb stairs instead of taking the elevator. Walk your dog; play with your kids. It doesn't have to be an hour in the gym or a 45-minute dance class. But that's great when you're up to it. At the same time, move more.

    Quit Smoking

    Ever since 1960 when it was announced that smoking was harmful to health, Americans have been reducing their use of tobacco products. Just recently, we've seen more and more teens smoking. Could it be the Hollywood influence?

    {#blank#}2{#/blank#} Take care! Warn your children against smoking.

    {#blank#}3{#/blank#}

    While recent studies show a glass of wine or one drink a day can help protect against heart disease, more than can cause other health problems such as liver and kidney (肝肾) disease and cancer.

    Reduce Stress

    Easier said than done, stress comes in many ways.{#blank#}4{#/blank#} Spend 30 minutes a day doing something you like such as walking on the beach or in a park, read a good book, visit a friend, listen to relaxing music, and watch a funny movie.

    Protect Yourself From Pollution

    If you can't live in a smog-free environment, at least avoid smoke-filled rooms, {#blank#}5{#/blank#} Exercise indoors in air conditioning when air quality is good.

A. Avoid Excessive Drinking

B. There are many things you can do to move your arms and legs.

    No fight can end, and no friendship can move on, until everyone says these little words: I'm sorry. Sometimes, though, it can be difficult to say them. {#blank#}1{#/blank#}

    It is not about winning.

    {#blank#}2{#/blank#} When you start fighting with a friend, you may feel it is important that you “win” the fight by proving you're right and he is wrong, or by making him the first to apologize. In reality, you'll both lose if you let your fight ruin your friendship, and you'll both win if you find a way to heal it.

    {#blank#}3{#/blank#}

    You may have heard the expression "His pride stood in the way." It is usually used to describe a person who is so determined to be "right" that he lets an opportunity for happiness pass him by forever. {#blank#}4{#/blank#} Remember that as time goes by, we usually forget who was right and who was wrong in a disagreement, and only remember the sadness of losing a friend.

    Take the first step.

    Are you sick of fighting? Do you think this fight is just not important enough to ruin your friendship? {#blank#}5{#/blank#} You don't have to take full responsibility for starting the fight, or even say that your feelings were wrong. But you should find something you did or said that's worth apologizing for. If you say you're sorry, it's like an invitation for your friend to do the same. Once you've both said it, you'll both feel a million times better.

A. Stop thinking about your pride.

B. Then try to be the first to apologize.

C. Here are some things to keep in mind.

D. Don't let this happen to a friendship you care about.

E. It's about taking some responsibility for the argument.

F. There are some special moments when you shouldn't take the first step.

G. Friendships aren't like the Super Bowl, and there should never be the determination of a winner.

Dangerous Driving Habits

Approximately 1. 3 million people around the world die in road accidents every year, making it one of the top ten causes of deaths. {#blank#}1{#/blank#}To prevent these consequences, here are some dangerous driving habits you should avoid.

{#blank#}2{#/blank#}

Were you actually surprised by this one? Here's the truth — you're 23 times more likely to crash if you text while driving. {#blank#}3{#/blank#}Disturbingly, 77 percent of young adult drivers say they can safely drive while texting. Actually, distracted driving accidents, including those caused by the use of handheld devices, form the No. 1 killer of teens, according to the NHTSA and others.

Drive when you're tired.

Avoid driving when you're tired, since you will have slower reaction times and you are very likely to fall asleep at the wheel. If you're exhausted and your body needs sleep, it is going to get it, one way or another. {#blank#}4{#/blank#}If you're already in the car, pull over and take a nap and then continue when you've woken up. Having someone with you in the car can help prevent accidents, since you are more likely to be alert if you have company.

Keep an eye on the kids.

According to the AAA Foundation for Traffic Safety, passengers are ranked by drivers as among the most frequent causes of distraction（分心）. Young children are four times as distracting as adults, while infants can be eight times more distracting, the AAA Foundation reports. {#blank#}5{#/blank#}.
