Taking good notes is a time-saving skill that will help you to become a better student in several ways. {#blank#}1{#/blank#} Second, your notes are excellent materials to refer to when you are studying for a test. Third, note-taking offers variety to your study time and helps you to hold your interest.

    You will want to take notes during classroom discussions and while reading a textbook or doing research for a report. {#blank#}2{#/blank#} Whenever or however you take notes, keep in mind that note-taking is a selective process. {#blank#}3{#/blank#}

The following methods may work best for you.

●Read the text quickly to find the main facts and ideas in it.

●Carefully read the text and watch for words that can show main points and supporting facts.

●Write your notes in your own words.

●{#blank#}4{#/blank#}

●Note any questions or ideas you may have about what was said or written.

    As you take notes, you may want to use your own shorthand(速记). When you do, be sure that you understand your symbols and that you use them all the time. {#blank#}5{#/blank#}

    Reducing the amount of sleep affects students' performance at school. An American study asked schoolteachers to look at the effects of sleep restriction（限制） on children between six and twelve years of age. The teachers found that children who stayed up late had trouble thinking clearly and had more learning problems.

    {#blank#}1{#/blank#} Doctor Fallone now works at the Forest Institute of Professional Psychology in Springfield, Missouri. He presented the results last month at a science reporter conference in Washington, D. C. The Publication Sleep also reported the findings.

    The teachers were asked to complete weekly performance reports on seventy-four schoolchildren. The study lasted three weeks. During that period, Doctor Fallone and his team controlled the amount of sleep the children received.

    {#blank#}2{#/blank#} During another week, every child was kept awake later than normal. Each night, the youngest boys and girls had less than eight hours of sleep. The older ones were limited to six and a half hours. During the final week of the study, each child received no less than ten hours of sleep a night.

    The teachers were not told about how much sleep the students received. The study found that students who received eight hours or less had the most difficulty remembering old information. {#blank#}3{#/blank#}

    The study did not find that sleep restriction caused hyperactivity(极度活跃) in the children. {#blank#}4{#/blank#}

    Doctor Fall one said that the results provided experts and parents with a clear message: {#blank#}5{#/blank#}

    Please Don't Be Afraid To Travel On Your Own

    You want to travel. You make an unclear plan. {#blank#}1{#/blank#} But either way, you're leaving in six months time. You start doing research every single night.

    Of course, as this will be your first ‘real' travel experience, you naturally prefer to travel with other people. {#blank#}2{#/blank#} But the first friend you ask, perhaps your closest friend, turns you down and so you move on to the next friend. {#blank#}3{#/blank#} The third friend, the fourth friend and even that guy that you don't really like say no as well.

    {#blank#}4{#/blank#}You hope that one of your friends will change their mind and decide to join you. Maybe you decide to forget about your trip altogether, fully believing that you can only travel so far away from home with a friend or travel companion (同伴) by your side.

    Don't give up just yet. Here's my advice to you. You may be on your own when you board that flight to Bangkok or Mexico City, but believe me, once you arrive, you'll never actually be alone. That's how travel works. Unless you stare at the ground and never talk to anyone, you're going to meet people when you travel, lots and lots of people from all over the world. {#blank#}5{#/blank#}

A. Don't give it up.

B. Maybe you'll fly to Thailand or to Mexico.

C. Meeting new people is one of the worst things to do.

D. But they too, tell you they have no interest to join you at all.

E. They will be interested in meeting and hanging out with you.

F. So you start asking your friends to join you in your journey.

G. Maybe you decide to put off your trip for another six months.

    Can just one person make a difference? You bet! In a community every person counts, and getting involved is not difficult. Take stock of your own talents and interests. {#blank#}1{#/blank#} Don't wait for someone else to act first. Take the initiative! Once you see what you can accomplish, you'll want to keep going.

    Here are just a few ways to make a difference in your community. How many more ways can you come up with?

    Clean up the community. People often throw litter in places where there is already litter. And the problem only becomes worse until someone gets fed up and does something. Could your neighborhood use a cleanup? Neighborhood cleanups are often sponsored by local businesses or schools. But if your community doesn't have a cleanup program, get together with friends to organize one. You could pick up garbage in a larger area twice a year, or you could clean a smaller area every few months. {#blank#}2{#/blank#}

    Include the isolated. Do you know anyone who is housebound? Almost all neighborhoods have a few people who have to stay at their homes. These people are often elderly and unable to leave their homes to perform simple tasks. {#blank#}3{#/blank#} By letting them "borrow" your legs and eyes, you can make them feel included. You can run errands for them like shopping or paying bills. They might like you to read to them if their eyesight is failing. Governments provide some of the services these people need, but programs cannot give them friendship; that's what communities are for!

    {#blank#}4{#/blank#} Reading clubs are popular all over Europe and North America. Members might read at home to prepare for discussion, or they might read aloud to each other and talk about what they just read. Either way, a book or article can spark lively discussion and this often challenges people to take action.

A. Cleaning your community will have a positive effect on others in society.

B. They find a need or an issue you really care about.

C. But they belong to the community, too.

D. Living in a clean neighborhood will be its own reward.

E. Don't hesitate to take part in the community's activity.

F. Round up some readers.

Sustainable Cities Need More Than Parks, Cafes and a Riverwalk

    There are many standards that aim to rank how green cities are. But what does it actually mean for a city to be green or sustainable?

    We've written about what we call the "parks, cafes and a riverwalk" model of sustainability, which focuses on providing new green spaces, mainly for high-income people. This vision of shiny residential towers and waterfront parks has become a widely-shared conception of what green cities should look like. {#blank#}1{#/blank#}

    Gentrification(住宅高档化) has become a catch-all term used to describe neighborhood change, and is often misunderstood as the only path to neighborhood improvement. In fact, its defining feature is displacement. Typically, people who move into these changing neighborhoods are wealthier and more educated than residents who are displaced.

    A recent flood of new research has focused on the displacement effects of environmental cleanup and green space initiatives. {#blank#}2{#/blank#}

    Land for new development and resources to fund extensive cleanup of poisonous sites are scarce in many cities. {#blank#}3{#/blank#} And in neighborhoods where gentrification has already begun, a new park or farmers market can worsen the problem by making the area even more attractive to potential high-income people and pricing out long-term residents. In some cases, developers even create temporary community gardens or farmers markets or promise more green space than they eventually deliver, in order to market a neighborhood to buyers looking for green pleasantness.

    {#blank#}4{#/blank#} It makes deindustrialization seem both inevitable and desirable, often by quite literally replacing industry with more natural-looking landscapes. When these neighborhoods are finally cleaned up, after years of activism by longtime residents, those advocates often are unable to stay and enjoy the benefits of their efforts.

A. This phenomenon is often missing from development projects promoted as green or sustainable.

B. This phenomenon has variously been called environmental, eco-or green gentrification.

C. Greening and environmental cleanup do not automatically or necessarily lead to gentrification.

D. This creates pressure to rezone industrial land for residential towers or profitable commercial space, in exchange for developer-funded cleanup.

E. But it can drive up real estate prices and displace low- and middle-income residents.

F. Environmental gentrification naturalizes the disappearance of manufacturing and the working class.

    A 2014 study found that readers of a short mystery story on a Kindle were significantly worse at remembering the order of events than those who read the same story in paperback.

    The brain reads by constructing a mental representation of the text based on the placement of the page in the book and the word on the page. The tactile (触觉的) experience of a book aids this process, from the thickness of the pages in your hands as you progress through the story to the placement of a word on the page.

    Surveys about the use of e-readers suggests that this affects a reader's sense of control. The inability to turn back to previous pages or control the text physically, either through making written notes or bending pages, limits one's sensory experience and thus reduces long-term memory of the text.

    Before the Internet, the brain read in a linear (线状的) fashion, taking advantage of sensory details to remember where key information was in the book by layout.

    As we increasingly read on screens, our reading habits have adapted to skim a text rather than really absorb its meaning. A 2006 study found that people read on screens in a "F" pattern, reading the entire top line but then only scanning through the text along the left side of the page. This sort of nonlinear reading reduces comprehension and actually makes it more difficult to focus the next time you sit down with a longer piece of text.

    Tufts University neuroscientist Maryanne Wolf worries that "the superficial way we read during the day is affecting us when we have to read with more in-depth processing." Individuals are increasingly finding it difficult to sit down and involve themselves deeply in a novel. As a result, some researchers and literature-lovers have started a "slow reading" movement, as a way to counteract their difficulty making it through a book.

    Slow-reading advocates recommend at least 30 to 45 minutes of daily reading away from the distractions of modern technology. By doing so, the brain can reengage with linear reading. The benefits of making slow reading a regular habit are numerous, reducing stress and improving your ability to concentrate.

    Reading an old-fashioned novel is also linked to improving sleep. When many of us spend our days in front of screens, it can be hard to signal to our body that it's time to sleep. By reading a paper book about an hour before bed, your brain enters a new zone, distinct from that enacted by reading on an e-reader.
