It is now mandatory(强制) for drivers or passengers to wear seatbelts while in a car in all states. In addition, it is also mandatory for kids of be in some kind of specialized car seat. Given the strict requirements in other vehicles, why don't buses have seatbelts?

    The main answer, at least for school buses, is that seatbelts do not make school buses safer. Overall, traveling on school buses is the safest way to travel—40 times safer than riding in a car—with only a handful of deaths occurring to passengers on school buses every year. The seats on the school bus are placed very close to each other and have high backs that are thickly padded. As a result, in an accident the students would be propelled forward a very short distance into a padded seatback that in a way is like an airbag. In addition, the fact that people sit high off the ground on school buses also makes it safer to travel on them.

    While school buses feature high backed seats and elevated seating locations, the same cannot be said of city buses. However, from a practical angle, there's little need to require seatbelts on city buses. Although the design of the modern low—floor city bus is less safe than the design of school buses, the fact that city buses rarely travel at speeds greater than 35 miles per hour means that any collision is likely to be small, Also, given that most trips on city buses are short and that many trips have standing passengers, the presence of seatbelts will make even less of a difference.

    Another answer why buses do not have seatbelts is cost. It is estimated that adding seatbelts to buses would add between $8,000 and $15,000 to the cost of each bus. In addition, seatbelts would take up room currently used as seats, meaning that each bus would have fewer seating places. The additional room in the bus taken up by seatbelts would mean that bus fleets would have to increase by as much as 15% just to carry the same number of people. Such an increase would be especially difficult in cities that experience overcrowding on their vehicles.

    Regardless of whether their passengers have seatbelts, all buses provide seatbelts for drivers and most bus companies make their drivers wear seatbelts in order not to be influenced by a collision.

    Curiosity is an important characteristic of a genius. I don't think you can find an intellectual giant who is not a curious person. Thomas Edison, Leonardo da Vinci, Albert Einstein, Richard Feynman, they are all curious characters. Richard Feynman was especially known for his adventures which came from his curiosity.{#blank#}1{#/blank#} Here are four reasons:

    It makes your mind active and strong.

    {#blank#}2{#/blank#}Their minds are always active. Since the mind is like a muscle which becomes stronger through continual exercise, the mental exercise caused by curiosity makes your mind stronger and stronger.

    It makes your mind observant of new ideas.

    When you are curious about something, your mind expects new ideas related to it. When the ideas come they will soon be recognized.{#blank#}3{#/blank#} This is because your mind is not prepared to recognize them. Just think, how many great ideas may have lost due to lack of curiosity?

    {#blank#}4{#/blank#}

    By being curious you will be able to see something new that is normally not visible. They are hidden behind the surface of normal life, and it takes a curious mind to look beneath the surface and discover the unknown.

    It brings excitement into your life.

    The life of curious people is far from boring. It's neither dull nor routine. There are always new things that attract their attention and there are always new “toys” to play with.{#blank#}5{#/blank#}

A. So is curiosity that important?

B. But why is curiosity so important?

C. It leads you to a new and exciting life.

D. It opens up new worlds and possibilities.

E. Curious people always ask questions and search for answers.

F. Rather than get bored, curious people have an adventurous life.

G. Without curiosity, the ideas may pass right in front of you and yet you miss them.

    We all know that a hot, milky drink and a warm bath are supposed to relax you before bed, but many of us still can't slip into sleep. Here are some tips to help you go to sleep.

    Breathe in through your left nostril(鼻孔)

    {#blank#}1{#/blank#}. Sleep specialist Peter Smith says, "Lie on your left side, resting a finger on your right nostril to close it. Start slow, deep breathing in the left nostril." Peter, author of Sleep Better With Natural Therapies, says this technique is particularly good when overheating is preventing sleep.

    Relaxing all your muscles can prepare your body for sleep. Anxiety expert Charles Linden says: "Lying on your back, take a deep, slow breath in through your nose and, at the same time, squeeze your toes tightly as if you are trying to curl them under your foot, then loosen them slowly. Breathe again, contract your leg muscles, then your thigh, belly, chest, arms, and so on until you heat all the way up your body. {#blank#}3{#/blank#}.

    Try to stay awake

Challenge yourself to stay awake— your mind will fight against it! "It's called the sleep paradox(悖论)." says psychotherapist Julie Hirst. She explains: "Keep your eyes wide open, repeat to yourself 'I will not sleep. {#blank#}4{#/blank#}, but instead view this as an instruction to sleep and eye muscles tire quickly as sleep turns up."

    {#blank#}5{#/blank#}

    Use at least three senses imagining yourself in a situation where you feel content—a paradise(乐园), sailing on calm waters, walking in flower fields.

A. Just imagine

B. Enjoy a paradise

C. Squeeze and relax

D. The brain doesn't process negatives well

E. You must repeat what you have done

F. This yoga method is thought to reduce blood pressure and calm you

G. When you have gone from head to toe, you should feel ready for sleep

Live Every Day Like It's A Holiday

    We feel great on holiday because we let go of everyday stresses and strains. {#blank#}1{#/blank#} So whether or not you're going away this summer, there's plenty you can do to make sure you benefit from that holiday feeling.

    Sleep like a holidaymaker

    Sleep like a baby when you're on your holidays but stay awake when you're in your usual routine? {#blank#}2{#/blank#}  To reset your sleep pattern, avoid bringing problems to bed. That includes your phone, TV or laptop. Make sure the room is dark and cool. Aim for at least seven hours' ZZZs—just as you would on holiday.

    Get moving

    {#blank#}3{#/blank#} Given that exercise is cheap, healthy and reduces stress, it makes absolute sense to build it into your day. A walk will release happy hormones, and eases anxiety and mild depression. {#blank#}4{#/blank#} 

    Part of the joy of going away is lingering over delicious food with families. Take up the holiday habit of sitting down as a family for at least one meal a day. Families who eat together experience less anxiety, less depression and less obesity, research has found.

    Be a tourist in your own city

    Part of toe thrill of a holiday is the novelty of discovering a new place and doing new things. {#blank#}5{#/blank#} At weekends, check out a new music venue, visit a different museum or have a drink in that interesting-looking pub you're always walking past. It will get you out of routine and make you feel alive. A bit like a holiday, really.

A. Make your meals a celebration.

B. Carve out some dedicated quiet time.

C. If so, you might need to examine your sleep habits.

D. Just make sure you schedule it into your day or week.

E. But it's also easy to be a holidaymaker in the place you live.

F. Research has even shown that vacations help health and wellbeing.

G. When you're travelling, you walk around new cities without a second thought.

    Reading books can be a great way to pick up new vocabulary, see grammar in action and develop your understanding of a language. {#blank#}1{#/blank#}

    For beginners, I would recommend starting with something short and simple. Avoid the classics, for they often use very old English words and can involve complex themes. Children's books are a great place to start. {#blank#}2{#/blank#} Dr Seuss writes his books in thyme and they are all very funny. Starting with something like this means you are more likely to finish the book and want to read more.

    {#blank#}3{#/blank#} The book isn't too long and if you've seen the film it may be easier to follow. If you like reading about historical events, Anne Holm's I am David is a good read.

    If you're not quite ready to read a full book, why not try Roald Dahl's Revolting Rhymes? {#blank#}4{#/blank#} Or, try a very short book like one from Roger Hargeaves's Mr. Men and Little Miss series. Although they are intended for young children, they are a good way to pick up some more basic vocabulary.

    My final piece of advice would be to read something that interests you. Look at the short summary of the book on the back cover and see if it looks like something that you would enjoy. Think about the type that is in your own language and find one of that type in English. {#blank#}5{#/blank#}

A. Dr Seuss's books are guaranteed to make you laugh.

B. The key to success is choosing the right book for you.

C. Reading can bring you a lot of fun as well as knowledge.

D. For more advanced learners, you could try the Hobbit by J.R.R. Tolkien.

E. This way, you're more likely to enjoy reading, rather than see it as a headache.

F. How much you can understand a book depends on your vocabulary.

G. This book contains lots of short stories, based on fairy tales, all written in thyme.

    When everything goes wrong, always look at what you have, instead of what you have lost. Because it's not what the world takes away from you that counts; it's what you do with what you have left.{#blank#}1{#/blank#}

    Pain is part of growing.

    Sometimes life closes doors because it's time to move forward. {#blank#}2{#/blank#}When times are tough, remind yourself that no pain comes without a purpose. Remember that there are two kinds of pain: pain that hurts and pain that changes you. When you roll with life, instead of resisting it, both kinds help you grow.

    {#blank#}3{#/blank#}

    Every time you get hurt, you heal. After darkness there is always light – you are reminded of this every morning, but still you often forget, and instead choose to believe that the night will last forever. It won't. Nothing lasts forever.

    Complaining changes nothing.

    {#blank#}4{#/blank#}It's always better to attempt to do something great and fail than to attempt to do nothing and succeed. It's not over if you've lost; it's over when you do nothing but complain about it. If you believe in something, keep trying. Don't let the shadows of the past darken the doorstep of your future.

    The best thing you can do is to keep going.

Don't be afraid to get back up—-to try again, to love again, to live again, and to dream again. Don't let a hard lesson harden your heart. Life's best lessons are often learned at the worst times and from the worst mistakes. There will be times when it seems like everything that could possibly go wrong is going wrong.{#blank#}5{#/blank#}

A. Everything in life is temporary.

B. And even if you fall short, keep going.

C. Your scars are symbols of your strength.

D. Those who complain the most, accomplish the least.

E. Here are a few tips to inspire you when you need it most.

F. That's a good thing because we often won't move unless life forces us to.

G. When you feel like quitting, remember that sometimes things can be right eventually.
