You Can Fly More Frequently

    When traveling, airfare can take up a large part of your travel budget. What if you could fly practically for free? If it were possible, then you would probably travel more, right?{#blank#}1{#/blank#} While it may seem like a lot of work to accumulate miles, it's pretty easy when you know how.

    Sign up for mileage (里程) programs. You can't gain miles if you don't sign up.{#blank#}2{#/blank#} Pick one or two airlines that you use most often and try to bring all your points into those programs by flying with them.

    Buy gifts and have dinner out. Most mileage programs have a business list where you can register several credit or debit cards and then earn miles for each purchase you make through their participating shops or meal you have at restaurant partners.{#blank#}3{#/blank#}so why not make it count toward future travel?

    Use your credit card. Look for a card that gives you rewards. There are a ton of credit card companies that offer mileage cards that give you miles for each dollar you spend. Use it for bills, groceries, gas and anything else you would normally use your bank account for and then pay it off at the end of the month.{#blank#}4{#/blank#}

    Rent a car. Whenever you rent a car, you have the choice to include your frequent flyer member number.{#blank#}5{#/blank#} but it can be more beneficial to pay less than a dollar a day to earn one or more miles per dollar spent on your rental.

A. Some will charge a fee

B. With frequent flyer programs, you can

C. You're probably doing these things anyway

D. It's an easy way to accumulate miles and can add up really fast

E. In fact, you can get a free plane ticket just focusing on certain ones

F. Join frequent flyer programs, so you can start accumulating those miles

G. There are plenty of ways to earn money just by doing things you're already doing

    Would it surprise you to learn that, like animals, trees communicate with each other and pass on their wealth to the next generation?

    UBC Professor Simard explains how trees are much more complex than most of us ever imagined. Although Charles Darwin thought that trees are competing for survival of the fittest, Simard shows just how wrong he was. In fact, the opposite is true: trees survive through their co-operation and support, passing around necessary nutrition（营养）“depending on who needs it”.

    Nitrogen（氮）and carbon are shared through miles of underground fungi（真菌）networks, making sure that all trees in the forest ecological system give and receive just the right amount to keep them all healthy. This hidden system works in a very similar way to the networks of neurons（神经元）in our brains, and when one tree is destroyed, it affects all.

    Simard talks about “mother trees”, usually the largest and oldest plants on which all other trees depend. She explains how dying trees pass on the wealth to the next generation, transporting important minerals to young trees so they may continue to grow. When humans cut down “mother trees” with no awareness of these highly complex “tree societies” or the networks on which they feed, we are reducing the chances of survival for the entire forest.

    “We didn't take any notice of it” Simard says sadly. “Dying trees move nutrition into the young trees before dying, but we never give them chance.” If we could put across the message to the forestry industry, we could make a huge difference towards our environmental protection efforts for the future.

    Our personal strengths are part of what makes us unique as individuals, and part of the value we offer to the world around us. If we're not aware of our personal strengths, we can't use them well.{#blank#}1{#/blank#}

    The activities we enjoy often slow the skills we naturally have. Take a few moments to think about the things you really love doing and look at the potential parts that enrich these experiences for you.

    Ask trusted friends and family.

    {#blank#}3{#/blank#}Many of us come from cultures where it's polite to be modest, and this can make it hard to make out our own strengths without any outside help. Ask trusted friends or family what they think your personal strengths are, and see if any of the answers surprise you.

    What qualities do you like in yourself?

    {#blank#}4{#/blank#}For example, if you like the fact that you stick to your goals, even when the going gets tough, one of your personal strengths might be determination.

    What makes you proud?

    Think about three examples in your life when you really felt proud of the way you acted or responded. {#blank#}5{#/blank#}What values did you display and why do you feel proud of the way you acted?

A. Notice what you enjoy.

B. Take a look at a list of personal strengths.

C. Sometimes it's hard to judge our strengths exactly.

D. Most of us have role models in our business and personal life.

E. What was it about your action or response that made you proud?

F. We potentially miss out on true achievements in our lie and careers

G. The qualities you like about yourself will show some of your personal strengths.

Children's Games in Ancient China

    Unlike the children nowadays, the children during ancient times didn't have smart phone, iPad or computer to entertain(娱乐) themselves. {#blank#}1{#/blank#} Let's take a look.

    Flying kites

    Kites have quite a long history. The earliest kites were made of wood, instead of paper. Nowadays, the three most famous kites are the Beijing kite, Tianjin kite and Weifang kite. {#blank#}2{#/blank#} For example, the swallow-shaped kite is a well-known Beijing style.

    Playing hide-and-seek

    Hide-and-seek is a traditional game for children, popular around the nation. Even nowadays, many children like playing it. There are two ways to play. One way is covering a child's eyes while other kids run around to tease(戏弄) him. {#blank#}3{#/blank#}

    {#blank#}4{#/blank#}

    The closest thing to watching a film or television for entertainment during ancient times was going to see a shadow play. Folk artists manipulate puppets behind the screen, narrating stories and accompanied by music.

    Setting off firecrackers(鞭炮)

    Firecrackers have a history of more than 2,000 years. It is said that there was a beast (野兽)named Nian in ancient China. {#blank#}5{#/blank#} After gunpowder was invented, it gradually replaced the bamboo joint cracker. Crackers are still set off during Spring Festival to symbolize auspiciousness(吉利).

A. Watching shadow plays

B. Each of them has special features.

C. Different materials are used to make the kite.

D. Shadow plays were the popular entertaining form in ancient times.

E. And to scare off the beast, people burnt bamboo joints to make it blast.

F. More commonly, participants hide and one child must try to find them.

G. Instead, they came up with(想出) interesting games to play in their childhood.

    Self-driving cars have been backed by the hope that they will save lives by getting involved in fewer crashes with fewer injuries and deaths than human-driven cars. But so far, most comparisons between human drivers and automated vehicles have been unfair.

    Crash statistics for human-driven cars are gathered from all sorts of driving situations, and on all types of roads. However, most of the data on self-driving cars' safety have been recorded often in good weather and on highways, where the most important tasks are staying in the car's own lane and not getting too close to the vehicle ahead. Automated cars are good at those tasks, but so are humans.

    It is true that self-driving cars don't get tired, angry, frustrated or drunk. But neither can they yet react to uncertain situations with the same skill or anticipation of an attentive human driver. Nor do they possess the foresight to avoid potential perils. They largely drive from moment to moment, rather than think ahead to possible events literally down the road.

    To a self-driving car, a bus full of people might appear quite similar to an uninhabited corn field. Indeed, deciding what action to take in an emergency is difficult for humans, but drivers have sacrificed themselves for the greater good of others. An automated system's limited understanding of the world means it will almost never evaluate (评估) a situation the same way a human would. And machines can't be programmed in advance to handle every imaginable set of events.

    Some people may argue that the promise of simply reducing the number of injuries and deaths is enough to support driverless cars. But experience from aviation (航空) shows that as new automated systems are introduced, there is often an increase in the rate of disasters.

    Therefore comparisons between humans and automated vehicles have to be performed carefully. To fairly evaluate driverless cars on how well they fulfill their promise of improved safety, it's important to ensure the data being presented actually provide a true comparison. After all, choosing to replace humans with automation has more effects than simply a one-for-one exchange.
