People are being lured(引诱) onto Facebook with the promise of a fun, free service without realizing they're paying for it by giving up large amounts of personal information. Facebook then attempts to make money by selling their data to advertisers that want to send targeted messages.

    Most Facebook users don't realize this is happening. Even if they know what the company is up to, they still have no idea what they're paying for Facebook because people don't really know what their personal data is worth.

    The biggest problem, however, is that the company keeps changing the rules. Early on, you keep everything private. That was the great thing about Facebook—you could create your own little private network. Last year, the company changed its privacy rules so that many things—your city, your photo, your friends' names—were set, by default(默认) to be shared with everyone on the Internet.

    According to Facebook's vice-president Elliot Schrage, the company is simply making changes to improve its service, and if people don't share information, they have a “less satisfying experience”.

    Some critics think this is more about Facebook looking to make more money. Its original business model, which involved selling ads and putting them at the side of the page, totally failed. Who wants to look at ads when they're online connecting with their friends?

    The privacy issue has already landed Facebook in hot water in Washington. In April, Senator(议员) Charles Schumer called on Facebook to change its privacy policy. He also urged the Federal Trade Commission to set principles for social-networking sites. “I think the senator rightly communicated that we had not been clear about what the new products were and how people could choose to use them or not to use them，” Schrage admits.

    I suspect that whatever Facebook has done so far to invade our privacy is only the beginning, which is why I'm considering deactivating (撤销) my account. Facebook is a handy site, but I'm upset by the idea that my information is in the hands of people I don't know. That's too high a price to pay.

    Today is National Bike-to-Work Day. And on New York City's jammed streets, people are cycling on hundreds of miles of new bike lanes. But New York's widespread efforts to make streets safer for bikes have also left some locals complaining about the loss of parking spots and lanes for cars.

    When the weather is good, Aaron Naparstek likes to pedal（用踏板踩） his two young kids to school on a special Dutch-made bicycle. Naparstek supports the new lane.

    Aaron: The bike lane on Prospect Park West is really introducing a lot of new people to the idea that it's possible to use a bike in New York City for transportation or to travel around. This is what 21^st century New York City looks like.

    Prospect Park West is still a one-way road, but where it used to have three lanes of car traffic, now it has two, plus a protected bike lane. Supporters say that makes the road safer for everyone, including pedestrians, by slowing down cars and taking bikes off the sidewalk. But some longtime residents disagree. Lois Carswell is president of a group called Seniors for Safety. She says the two-way bike lane is dangerous to older residents who are used to one-way traffic.

    Lois: We wanted a lane — the right kind of lane that would keep everybody safe, that would keep the bikers safe. But we want it to be done the right way. And it has not been done the right way.

    Craig Palmer builds bars and restaurants in Manhattan. I was interviewing him for a different story when he brought up the bike lanes all on his own.

    Craig: I think the biggest problem is that Bloomberg put all these bike lanes in. You took what used to be a full street and you're shrinking it.

    Then there are the Hasidic Jews in Williamsburg, Brooklyn, who forced the city to remove a bike lane through their neighborhood. But polls show that the majority of New Yorkers support bike lanes by a margin of 56% to 39%. Bicycle advocate Caroline Samponaro of Transportation Alternatives calls that a mandate.

    Caroline: If this was an election, we would have already had our victory. The public has spoken and they keep speaking. And I think, more importantly, the public is starting to vote with their pedals.

    When asked about happiness, we usually think of something extraordinary, an absolute delight, which seems to get rarer the older we get.

For kids, happiness has a magical quality. Their delight at winning a race or getting a new bike is unreserved (毫无掩饰的).

    In the teenage years the concept of happiness changes. Suddenly it's conditional on such things as excitement, love and popularity. I can still recall the excitement of being invited to dance with the most attractive boy at the school party.

    In adulthood the things that bring deep joy—love, marriage, birth—also bring responsibility and the risk of loss. For adults, happiness is complicated (复杂的).

    My definition of happiness is “the capacity for enjoyment”. The more we can enjoy what we have, the happier we are. It's easy to overlook the pleasure we get from the company of friends, the freedom to live where we please, and even good health.

    I experienced my little moments of pleasure yesterday. First I was overjoyed when I shut the last lunch-box and had the house to myself. Then I spent an uninterrupted morning writing, which I love. When the kids and my husband come home, I enjoyed their noise after the quiet of the day.

    Psychologists tell us that to be happy we need a mix of enjoyable leisure time and satisfying work. I don't think that my grandmother, who raised 14 children, had much of either. She did have a network of close friends and family, and maybe this what satisfied her.

    We, however, with so many choices and such pressure to succeed in every area, have turned happiness into one more thing we've got to have. We're so self-conscious about our “right” to it that it's making us miserable. So we chase it and equal it with wealth and success, without noticing that the people who have those things aren't necessarily happier.

    Happiness isn't about what happens to—it's about how we see what happens to us. It's the skillful way of finding a positive for every negative. It's not wishing for what we don't have , but enjoying what we do possess.

    Tyler Skiuzacek's father，Patrick，could not sleep through the night．It was 2007，and Patrick had just returned from a year in Iraq，where he served in the U．S．Army．Patrick Skluzacek was energetic and happy when he left for Iraq，Tyler says．But when he returned，he was unhappy and drinking alcohol too much．It turned out Patrick was suffering from sleep panic attacks．Patrick would wake up every night．His heart would beat too fast．He would sweat．The nighttime panic attacks prevented Patrick from feeling good the next day，because he was so tired．

    Almost 10 years later，Tyler was in a position to help his father．He thought he could make a computer program that might help his father．So he entered a competition in Washington，D．C，trying to solve the problem Tyler's father and other U．S．war veterans(老兵)，were having．People called them “night terrors.”The students had 36 hours to come up with a program．They called it myBivy．That name comes from bivouac，a military term for a safe place to sleep．

    The application uses a smart watch and a smart phone together．The watch tracks the wearer's heartbeat．It sends the data to the program on the smart phone．Research shows that a person's heart rate will increase right before a night terror．So if the wearer's heartbeat started to rise，my B ivy would respond．The smart watch would vibrate(振动)and gently wake up the sleeping person．That was enough to prevent a night terror from happening．

    Patrick wore the watch for two weeks to get used to it．Then，Tyler turned on the application．On the first night，the vibrations from the watch prevented 10 nightmares．Patrick said he had not slept that well in many years．Tyler and his team won the contest in Washington，D．C．The prize was $1，500．Then the group tried to raise more money from investors，and they were surprised when they took in over$25，000．By the spring of 2016，Tyler and his team were testing the app with volunteers，and hoped to make it availab1e to the public soon．

    The human-caused rise in CO₂ hasn't yet reached its full warming effect, owing to the considerable delay in its impact on ocean temperature. There is still another 0.5^oC of so of warming to occur over the coming decades based on the current concentrations（浓度）of CO₂ in the atmosphere, and far more warming beyond that if CO₂ concentrations continue to rise greatly with the business-as-usual burning of fossil oil. To improve the situation, the world needs to shift firmly from coal, oil and gas to renewable energy by around 2050 and from cutting down trees to planting trees and restoring degraded lands.

    So why do human begins keep dashing in a stupid way ahead, toward certain tragedy?

    The main reason is that our political institutions and giant corporations intentionally ignore the rising dangers and damage.   ①    Managing a major company is about maximizing shareholder value, not about telling the truth or avoiding great harm to the planet. Profit -seeking investors own the major media, or at least influence them through their advertising purchases. Thus, a small yet very powerful group keeps the fossil-fuel-based energy system at growing dangers to the rest of humanity today and in the future.

    We need a new kind of politics that starts with a clear goal: environmental safety for the planet's people, by fulfilling the Paris agreement, protecting biodiversity, and cutting pollution, which kills millions each years.   ②    The new politics will listen to scientific and technological experts, not self-interested business leaders and politicians.

       ③    Such a politics is possible. In fact, the public longs for it. A large majority of the American people,for example, want to fight global warming, stay in the Paris climate agreement, and support renewable（可更新的）energy. Yet, as long as a narrow and ignorant elite（精英）judges Americans and the rest of human beings to wander aimlessly in the political desert, the more likely it is that we will end up in a wasteland from which there will be no escape.  ④
