MOOCs _________ made waves in the fall of 2011, when Professor Sebastian Thrun from Stanford University opened his graduate-level artificial intelligence course up to any student anywhere, and 160,000 students in more than 190 countries _________. This new kind of online classes is _________ the higher education world in many ways. Since the courses can be taken by hundreds of thousands of students at the same time, the number of universities might _________ greatly. Professor Thrun has even _________ a future in which there will only need to be 10 universities in the world.

【推荐3】Studies show that older people tend to remember the positive things in life rather than the negative things, while younger people remember the positive and negative equally well. The dominant psychological theory to explain this is that older people are aware of their limited time left, so they _______ positive emotional experiences. But about a decade ago, I worked with biologist Robert Trivers on his idea that there was a(n) _______ basis for older people's increased positive outlook. Our research took us in the fascinating direction of exploring how the body _______ its energy.

When our _______ needed more energy than usual perhaps while being chased by a tiger, they had to get that energy from somewhere in the body. Could they borrow it from the brain? That organ uses 20 percent of our metabolic output, whether we are solving math problems or watching television reruns. Due to this constant energy requirement, borrowing energy from the brain when our need _______ the available supply is not an option. Perhaps we could borrow energy from our muscles. Because we use far more muscle energy when we are active than when at rest, _______, we could borrow energy when we are sitting. But the problem is that most of the energy-demanding emergencies of our ancestors _______ a muscular response. There was no way to borrow energy from our muscles during an emergency because relaxing when a tiger showed up was not a(n) _______ response. This brings us to our immune system, which, when _______ protects us from many illnesses and diseases. Like the brain, the immune system works at great metabolic cost, but largely in the __________of keeping us healthy in the future. We have an enormous number of immune cells coursing through our body, a(n) __________ break from production is fine. So, when our body needs extra energy, one of the places it goes is our immune function. When you’re being chased by a tiger, you don’t need to waste energy making immune cells to fight off tomorrow’s cold. What you need is to __________ all available energy resources to your legs, with the hope that you will live to experience another cough or sneeze.

__________, our immune system evolved to run in maximum amounts when we’re happy, but to slow down dramatically when we’re not. With this background in mind, Trivers supposed that older people evolved a strategy of turning this relationship on its head, becoming more __________ the positive things in life in an effort to enhance their immune functioning. This was helped along by their knowing much more about the world than younger adults, so they can deal with some of the __________ things in life more easily.

【推荐2】The requirements for high school graduation have just changed in my community. As a result, all students must _______ sixty hours of service learning, _______ they will not receive a diploma. Service learning is academic learning that also helps the community. _______ of service learning include cleaning up a polluted river, working in a soup kitchen, or tutoring a student. _______ a service experience, students must keep a journal and then write a _______ about what they have learned.

Supporters claim that there are many _______ of service learning. Perhaps most importantly, students are forced to think _______ their own interests and become _______ of the needs of others. Students are also able to learn real­life skills that _______ responsibility, problem­solving, and working as part of a team. ________ students can explore possible careers ________ service learning. For example, if a student wonders what teaching is like, he or she can choose to work in an elementary school classroom a few afternoons each month.

________ there are many benefits, opponents ________ problems with the new requirement. First, they ________ that the main reason students go to school is to learn core subjects and skills. Because service learning is time­consuming, students spend ________ time studying the core subjects. Second, they believe that forcing students to work without ________ goes against the law. By requiring service, the school takes away an individual’s freedom to choose.

In my view, service learning is a great way to ________ to the community, learn new skills, and explore different careers. ________, I don’t believe you should force people to help others — the ________ to help must come from the heart. I think the best ________ is one that gives students choices: a student should be able to choose sixty hours of independent study or sixty hours of service. Choice encourages both freedom and responsibility and as young adults, we must learn to handle both wisely.
