    People are being lured(引诱) onto Facebook with the promise of a fun, free service, {#blank#}1{#/blank#} realizing that they're paying for it by giving up plenty of personal information. Facebook then attempts to make money by selling their data to advertisers that want to send{#blank#}2{#/blank#} (target) 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 {#blank#}3{#/blank#} they're paying for Facebook, because people don't really know what their personal details are worth.

    The biggest problem, however, is that the company keeps changing the rules.  Early on, you could 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 {#blank#}4{#/blank#} 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 “{#blank#}5{#/blank#} (satisfying) experience.”

    Some critics think this is more about Facebook looking to make more money. Its original business model, {#blank#}6{#/blank#} involved selling ads and putting them at the side of the page, totally failed. Who wants to look at ads when they are connecting with their friends online?

    So far the privacy issue {#blank#}7{#/blank#} (land) Facebook in hot water in Washington. In April, Senator Charles Schumer called on Facebook to change its privacy policy.  He also urged the Commission to set regulations for social-networking sites.

    I suspect that whatever Facebook has done {#blank#}8{#/blank#} (invade) our privacy is only the beginning, which is why I'm considering {#blank#}9{#/blank#} (cancel) my account.  Facebook is a handy site, but I'm upset by the idea that {#blank#}10{#/blank#} information is in the hands of people I don't trust. That is too high a price to pay.

    Happiness can {#blank#}1{#/blank#}(describe) as a positive mood and a pleasant state of mind. There are many factors contributing to happiness.

A person {#blank#}2{#/blank#} an obviously ideal situation is not necessarily happy. The ideal situation may have little to do with his actual feelings.

A good education and income are usually considered necessary for happiness. Though both may contribute, {#blank#}3{#/blank#} are only chief factors if the person is {#blank#}4{#/blank#}(serious) undereducated or actually suffering from lack of physical needs.

    The rich {#blank#}5{#/blank#}(be) not likely to be happier than the middle-income group or even those with very low incomes. People with college educations are somewhat happier than those who did not graduate from high school, and it is believed that this is mainly {#blank#}6{#/blank#} they have more opportunity to control their {#blank#}7{#/blank#}(life). Yet people with a high income and a college education may be {#blank#}8{#/blank#}(little) happy than those with the same income and no college education.

    Poor health does not rule out happiness except for the severely {#blank#}9{#/blank#}(disable) or those in pain. Learning {#blank#}10{#/blank#}(cope) with a health problem can contribute to happiness.

    China's first artificial intelligence (Al) textbook for high school students {#blank#}1{#/blank#}(bring) out last week, following a plan by central government {#blank#}2{#/blank#}(include) Al courses in primary and secondary school.

    The nine - chapter textbook, {#blank#}3{#/blank#}(name) " Fundamentals of Artificial Intelligence" , was written by outstanding {#blank#}4{#/blank#}(scholar) from well - known schools nationwide, under the joint efforts by the research center for MOOC at East China Normal University and Al startup SenseTime. It includes the history of Al and how the technology can be applied in areas such as facial recognition, auto driving and public security.

    "The textbook focuses not only on basics of Al, but on {#blank#}5{#/blank#}(practice) use of Al in daily life," said Chen Yukun, a professor at East China Normal University, {#blank#}6{#/blank#} is also a contributor to the book.

    Up till now, about 40 high schools across the country {#blank#}7{#/blank#}(undertake) the task of being the first group of Al high education pilot program {#blank#}8{#/blank#} introducing the textbook in the curriculum. "The Al sector is facing a talent shortage {#blank#}9{#/blank#}(global). The publication of the book is {#blank#}10{#/blank#}breakthrough as it takes Al technology out of the 'Ivory tower' and makes it part of high school learning," said Lin Dahua, a professor at the Chinese University of Hong Kong.

    Chinese President Xi Jinping {#blank#}1{#/blank#}(review) the armed forces at the heart of Beijing Tuesday morning, {#blank#}2{#/blank#}(he) first on National Day, to mark the 70th founding anniversary of the People's Republic of China.

    {#blank#}3{#/blank#} (stand) in a black open-roof Red Flag limo (轿车), Xi gave the order to start the review. At {#blank#}4{#/blank#} beginning, with the limo {#blank#}5{#/blank#} (slow) passing the fluttering (飘荡的){#blank#}6{#/blank#}(flag) of the CPC, the nation and the People's Liberation Army (PLA) in Tian'an men Square, Xi watched them {#blank#}7{#/blank#} full attention as a salute(致敬). During the military music {#blank#}8{#/blank#} (play) by a military band, the Red Flag limo drove eastward along Chang'an Avenue, {#blank#}9{#/blank#} was lined with 15,000 service men and women as well as 580 pieces of weapons. Xi repeated salutes through microphone and the soldiers gave loud replies{#blank#}10{#/blank#}the limo drove back to Tian'an men Rostrum.
