In a recent announcement, Harvard and the Massachusetts Institute of Technology（MIT）said that they have joined forces to offer free online courses in an effort to attract millions of online learners worldwide.

    Beginning this fall, a number of courses developed by teachers at both universities will be offered online through a new $60 million program, known as edX. “Anyone with an Internet connection anywhere in the world can use our online courses,” Harvard President Drew Faust said during a meeting to announce the plan.

    MIT has offered a program called OpenCourseWare for ten years that makes materials from more than 2,000 classes free online. It has been used by more than 100 million people. In December, the school announced it also would begin offering a special certificate, known as MITx, for people who complete certain online courses. Harvard has long offered courses to a wider population through a similar program.

    The MITx will serve as the foundation for the new learning platform.

    MIT President Susan Hockfield said more than 120,000 people signed up for the first MITx course. She said Harvard and MIT hope other universities will join them in offering courses on the open-source edX platform.

     “Fasten your seatbelts,” Hockfield said.

    Other universities, including Stanford, Yale and Carnegie-Mellon, have been experimenting with teaching to a global population online.

    The Harvard-MIT program will be monitored by a not-for-profit（非盈利的）organization based in Cambridge, to be owned equally by the two universities. Both MIT and Harvard have provided $30 million to start the program. They also plan to use the edX platform to research how students learn and which teaching methods and tools are most successful.

    According to sociologists(社会学家), every modern industrial society has some form of social stratification(阶层). Class, power and status are important in deciding people's rank in society.

    Class means a person's economic position in society. A commonly used classification is lower class, middle class and upper class. While sociologists disagree on how these terms should be exactly defined, they do describe societies like the United States quite well. One study shows that 53% of Americans belong to the lower class, 46% the middle class, and 1% the upper class. Interestingly, a surgeon earning $500,000 a year and a bus driver earning $50,000 a year both regard themselves as the middle class!

    Power refers to the amount of control a person has over other people. Obviously, people in positions of great power (such as governors) exercise(行使)big power, but people who take orders from others have less power. Power and class do not always go hand in hand, however. For example, the governor of a state has great power, but he or she may not belong to a corresponding (相应的)economic class. Generally, however, there is a relationship between power and class. To our knowledge, there aren't too many people who aren't millionaires in the U．S. Senate!

    Status is the honor or respect attached to a person's position in society. It can also be affected by power and class, but not necessarily so. For example, a university professor may have a high status but not belong to a high social class or have a lot of power over others.

    Greece's finance minister says his country's financial situation is “terribly urgent” and the crisis could come to a head in a couple of weeks. Yanis Varoufakis gave the warning after eurozone finance ministers met in Brussels to discuss the final €7.2bn tranche(援助资金) of Greece's €240bn EU/IMF bailout(紧急援助).

    Ministers said Greece had made “progress” but more work was needed.

The Greek government is struggling to meet its payment obligations（责任）.Earlier, Greece began the transfer of €750m (£544m, $834m) in debt interest to the International Monetary Fund - a day ahead of a payment deadline.

    “The liquidity（资产流动性） issue is a terribly urgent issue. It's common knowledge, let's not beat around the bush,” Mr Varoufakis told reporters in Brussels. “From the perspective of timing, we are talking about the next couple of weeks.”

    Greece has until the end of June to reach a reform deal with its international creditors. Its finances are running so low that it has had to ask public bodies for help. The crisis has raised the prospect that Greece might default（违约） on its debts and leave the euro.

    In a statement, the eurozone finance ministers said they “welcomed the progress that has been achieved so far” in the negotiations,” but added: “We acknowledged that more time and effort are needed to bridge the gaps on the remaining open issues.” Eurogroup chairman Jeroen Dijsselbloem said there had to be a full deal on the bailout（紧急财务援助） before Greece received any further payments. “There are time constraints(限制；约束) and liquidity constraints and hopefully we will reach an agreement before time runs out and before money runs out.” he said.

    There had been fears that Greece would default on its IMF debt repayment due on Tuesday. However, a Greek finance ministry official was quoted as saying that the order for repayment had been executed（实施） on Monday. Almost €1bn has been handed over to the IMF in interest payments since the start of May.

    It is unclear how the government came up with the funds, but the mayor of Greece's second city Thessaloniki revealed last week that he had handed over cash reserves in response to an appeal for money.

    Subject: My school

Hi, Li Zijun,

    Thanks very much for your email. I really enjoyed reading it. I think we have a lot in common. I wonder if our school life is similar too.

    I go to a big high school in Sydney called Maylands High School. There are about 1000 students and 80 teachers. My class has 25 students in it, which is normal for a Year 11 class. In the junior school there are about 30 students in a class.

    In the senior high school we have lots of subjects to choose from, like maths, physics, chemistry, biology, history, German, law, geography, software design, graphic arts and media studies. (Different schools sometime have different optional subjects.) English is a must for everyone and we have to do least three other subjects in Year 11 and 12. At the end of Year 12 we sit for a public exam called the High School Certificate.

    As well as school subjects, most of us do other activities at school such as playing a sport, singing in the choir or playing in the school band. We can also belong to clubs, such as the drama club, the chess club and the debating society.

    We have a lot of homework to do in senior school to prepare for our exam, so unless I have basketball practice, I usually go straight home and start studying. I arrive home about 4 pm, make myself a snack and work till 6 pm. Then I help the family to make dinner and we all eat together. I'm usually back in my room studying by 8 pm. I stop at about 10 o'clock and watch TV or read a book for half an hour to relax. On Saturdays, I usually go out with my family or with friends and I sleep in till late on Sunday morning. Then it's back to the books on Sunday afternoon.

    How about you? What's your school life like? Do you have a lot of homework? What do you do to relax when you're not studying? I'm looking forward to finding out.

    Once there was an old man, who was completely broke (破产的), living in a tiny house. He had to live on a $105-a-month social security (保障) check.

    At 65 years of age, he decided things had to change. So he thought about what he had to offer. His friends thought highly of his chicken recipe (烹饪法). He decided that this was his best shot at making a change.

    He left Kentucky and traveled to different states to try to sell his recipe. He told restaurant owners that he had a mouth-watering chicken recipe. He offered the recipe to them for free, just asking for a small percentage (比例) on the items sold. Sounds like a good deal, right?

    Unfortunately, not to most of the restaurants. He heard "NO" over 1, 000 times, but he didn't give up. He believed his chicken recipe was something special. He got rejected (拒绝) 1,009 times before he heard his first yes.

    With that one success, the old man changed the way Americans eat chicken. Kentucky Fried Chicken, popularly known as KFC, was born. The old man was Colonel Harland Sanders, who was an American businessman, best known for founding fast food chicken restaurant chain Kentucky Fried Chicken. His name and image (肖像) are still symbols of KFC now.

    University of Pennsylvania researchers say that for the first time they have linked social media use to increases in depression and loneliness. The idea that social media is anything but social when it comes to mental health has been talked about for years, but not many studies have managed to actually link the two. To do that, Penn researchers, led by psychologist Melissa Hunt, designed a study that focused on WeChat, Snapchat and Instagram.

    The study was conducted with 143 participants, who before they began, completed a mood survey and sent along photos of their battery screens, showing how often they were using their phones to access social media. "we set out to do a study which attempts to imitate real life." Hunt said.

    The study divided the participants into two groups: The first group was allowed to maintain their normal social media habits. The other, the control group, was restricted to 10 minutes per day on social media. The restrictions were put in place for three weeks and then tested for now comes such as fear of missing out, anxiety, depression and loneliness.

    The results showed a very clear link between social media use and increased levels of depression and loneliness." Using less social media then you normally do would lead to significant decreases in both depression and loneliness " Hunt said.

    Social media invites what Hunt calls "downward social comparison." "When you're online, it can sometimes seem that everyone else is cooler and having more fun and included in more things and you're left out," Hunt said. And that's just generally discouraging. "Every minute you spend online is a minute you are not doing your work or not meeting a friend for dinner or having a deep conversation with your roommate." And these real life activities are the ones that you can encourage self-esteem and self-worth, Hunt added.

    "People are on their devices, and that's not going to change," she said. But as in life, a bit of control goes a long way.
