The Internet is full of headlines that grab your attention with buzzwords (流行词). But often when we click through, we find the content hardly delivers and it wastes our time. We close the page, feeling we've been cheated. These types of headlines are called "click bait".

    A headline on Businesslnsider.com reads: "This phrase will make you seem more polite". First, when you click through, you find another headline: "Four words to seem more polite." Then, on reading the article, you find it's actually an essay about sympathy. And what are the four words? They're "Wow, that sounds hard." On some video websites, you might encounter headlines such as "Here's what happens when six puppies visited a campus". Turns out it's just some uneventful dog footage (镜头).

    Nowadays, with the popularity of social media, many news outlets tweet (推送) click bait links to their stories. These tweets take advantage of the curiosity gap or attempt to draw the reader into a story using a question in the headline. These click bait headlines are so annoying that someone is attempting to save people time by exposing news outlet click bait through social media. The Twitter account @SavedYouAClick, run by Jake Beckman, is one such example.

    Beckman's method is to grab tweets linking to a story and retweet them with a click-saving comment. For example, CNET tweeted "So iOS 8 appears to be jailbreakable but...", with a link to its coverage of Apple's product announcements. Beckman retweeted it with this comment attached: "... it hasn't been jailbroken yet."

    Since founding the account, Beckman's Twitter experiment has brought him more than 131,000 followers. Beckman said that @SavedYouAClick is…"just my way of trying to help the Internet be less temble." Asked about his goal, he said, "I'd love to see publishers think about the experience of their readers first. I think there's an enormous opportunity for publishers to provide readers with informative updates that include links so you can click through and read more.

    Are you afraid of moving up to senior high school? It is a completely new experience, but you shouldn't worry. We've got a guide to help you.

    You're not alone. Remember that everybody else in your year is in the same boat. You may not notice it, but they're just as nervous as you are.

    Moving to senior high school is a chance, not a problem. Things are different, and all you need to do is to be polite and learn the new rules.

    The teachers will help. If you don't know what to do or are worried about something, then ask for help. Teachers are probably the best people to turn to, because they have experience in helping new students. Pay attention to what your teachers say.

    Everything changes. There are lots of differences between junior high school and senior high school. You will have your lessons with different teachers in different rooms. You will have homework for different subjects on different days, so make sure you get organised. Make sure you know which rooms your classes are in and which days you have your different subjects on.

Other points:

    If you've got an older brother or sister at the school, then ask them for advice.

    Be yourself! It sounds simple, but things will become better if you just act naturally.

    Having early nights makes a difference. You'll also find it easier to get up in the morning!

    It seems that no one can live a happy life without friendship. While a great number of people expect others to be their friends, they don't give friendship back. That is why some friendships don't last long. To have a friend, you must learn to be one. You must learn to treat your friend the way you want your friend to treat you. Learning to be a good friend means learning three rules: be honest; be generous; be understanding.

    Honesty is where a good friendship starts. Friends must be able to trust one another. If you do not tell the truth, people usually find out. If a friend finds out that you haven't been honest, you may lose your friend's trust. Good friends always depend on one another to speak and act honestly.

    Generosity means sharing and sharing makes a friendship grow. You do not have to give your lunch money or your clothes. Naturally you will want to share your ideas and feelings. These can be very valuable to a friend. They tell your friend what is important to you. By sharing them, you help your friend know better.

    Sooner or later everyone needs understanding and help with each other. Something may go wrong at school. Talking about the problem can make it easier to solve. Turning to a friend can be a first step in solving the problem. So to be a friend you must listen and understand. You must try to put yourself in your friend's place so that you can understand the problem better.

    No two friendships are exactly alike. But all true friendships have three things in common. If you plan to keep your friends, you must practice honesty, generosity and understanding.

    How to fight California's wildfires? It's an “all of the above” respond.

There might, indeed, be a need to make it easier to thin dying or dead trees out of thickly forested areas, reducing the fuel for wildfires. But the problem is actually more complicated. Even if dead trees are removed, the dry bushes act like kindling (引火物) when wildfires spread.

    Even more to the point, thick forests were not a factor in these recent California's fires. “They're using these fires to talk about forest management that has nothing to do with the landscape in which the fires are occurring,” says Chur Miller. W. M. Keck Professor of Environmental Analysis and History at Pomona College in Claremont, California.

    Climate change is making wildfires worse. The resulting unpredictable weather patterns have created shorter, wetter winters in California, producing a sudden, heavy growth of brushes, grasses and trees. After winter, the state's ongoing drought and record- high summer temperatures draw water out of the plants, making them near-perfect kindling. With the hot and dry Santa Ana winds of fall, fires explode out of control.

    Yet these tragedies can't be blame only on global warming. Wildfires are actually a vital of the state's ecosystem. Lodgepole pines (松树), for example, grow well in fire-prone areas where millions of structures have been built in rural areas of California since the 1940s.When they bum, the cost in lives and treasures skyrockets.

Answering these disasters with a one-dimensional solution helps no one, although it might score short-term political points. The proper response includes placing limits on residential expansion into wildlands; better management and removal of dry brushes and continuously addressing the growing concern of climate changes.

    In other words, the solution isn't either/or. It's all of the above.

    When people see machines that respond like humans, or computers that perform amazing feats of strategy, they sometimes joke about a future in which humanity will need to accept robot overlords. But buried in the joke is a seed of unease. Science fiction writing and popular movies have shown us about artificial intelligence (AI) that exceeds the expectations of its creators and escapes their control, eventually outcompeting and enslaving humans or targeting them for extinction(灭绝).

    Even in the real word, not everyone is ready to welcome AI with open arms. In recent years, as computer scientists have pushed the boundaries of what AI can accomplish, leading figures in technology and science have warmed about the frightening dangers that artificial intelligence may pose to humanity, even suggesting that AI capabilities could destroy the human race.

    But why are people so frightened about the idea of AI?

    Elon Musk is one of the famous voices that have raised red flags about AI, In July 2017. Musk told attendees at a meeting of the National Governors Association, I have exposured to the very cutting-edge Al, and I think people should be really concerned about it. I keep sounding the alarm bell. But until people see robots going down the street killing people, they don't know how to react, because it seems so impossible."

    Earlier, in 2014, Musk had labeled AI "our biggest existential threat," and in August 2017, he declared that humanity faced a greater risk from AI than the terrorists. Physicist Stephen Hawking, who died on March14, also expressed concerns about AI, telling the BBC in 2014 that "the development of full artificial intelligence could spell the end of the human race.
