Do you want to be productive（富有成效的）at work or at home? Here's what you should do.

Turn off television

    I used to tell myself that I needed a break. So, when the kids slept I turned on the cable and watched whatever program that caught my fancy. Often, I found myself not watching, just channel-surfing. And I didn't end up watching a full program. I decided one day to just give up on TV as it made me sleep late and woke up exhausted（疲惫的）.

    If you want to be productive, cut off TV. You are better off reading a book. Without TV, I have managed to finish many books which I have bought but never read.

Limit Internet Use

    The other big distraction that can make you sleep late is the Internet. Probably because you will be checking your emails, updating your blog, watching YouTube, etc. Try limiting the use of it at home, or switch it to the morning session.

    Nowadays, I check all my personal emails early in the morning. When I get into work, I find myself less tempted to check personal emails.

Know Your Priorities(优先考虑的事)

    Really, it is all about the choices you make and the priorities you have. If you know it is competitive out there in the world, how can you be a better worker than the person who is also aiming for the position above you?

Rest Early, Rise Early

    You want to be productive? Rise early, read more books, have more energy, be more focused and set standards for others to catch up. It's as simple as that.

    Have you ever heard of homecoming? It's a tradition celebrated every year in the US. At homecoming, a school or university welcomes back former students or alumni(校友).{#blank#}1{#/blank#}It means, “coming home.”

    This is a time when everyone can get together.{#blank#}2{#/blank#}There are events that encourage school spirit all throughout homecoming week, which leads to the big day on Friday.

    A major activity that most students will take part in is choosing the homecoming king and queen.{#blank#}3{#/blank#} This is a group of boys and girls who represent (代表) school spirit. At the end of the week, students vote for a boy and a girl to be the king and the queen.

    Then it's time for the football game, the main event of homecoming week! {#blank#}4{#/blank#}Almost everyone from school goes to the game: students, parents, teachers, and alumni visitors. If they win, everyone is very happy.

    {#blank#}5{#/blank#} Students dress up, and some might even bring a date to go with them. After the dance, homecoming is officially over, and everyone can't wait for next year!

A. The last event is the homecoming dance.

B. That is where the name comes from.

C. Students get to pick who will be on homecoming court early in the week.

D. The tradition began more than 100 years ago in the United States.

E. The football team faces a lot of pressure to do well for the big crowd.

F. Homecoming usually lasts a week and happens in the fall.

G. Homecoming week was not just about fun, but also a chance to try out new things.

    People can be addicted to(沉溺于) different things — e.g. alcohol, drug, certain foods, or even television. People who have such an addiction are compulsive(强迫的):They have a very powerful psychological（心理上的）need that they feel they must satisfy. According to psychologists, many people are compulsive spenders. They feel that they must spend money. This compulsion, like most others, is impossible to explain reasonably. For compulsive spenders who buy on credit(以赊欠方式), charge accounts are even more exciting than money. In other words, compulsive spenders feel that with credit, they can do anything. Their pleasure in spending large amounts is actually greater than the pleasure that they get from the things they buy.

    There is even a special psychology of bargain hunting. To save money, of course, most people look for sales, low prices, and discounts. Compulsive bargain hunters, however, often buy things that they don't need just because they are cheap. They want to believe that they are helping their budgets(预算), but they are really playing an exciting game. When they can buy something for less than other people, they feel that they are winning. Most people, experts claim, have two reasons for their behavior: a good reason for the things that they do and the real reason.

    It is not only scientists, of course, who understand the psychology of spending habits, but also business people. Stores, companies, and advertisers use psychology to increase business. They consider people's needs for love, power, or influence, their basic values, their beliefs and opinions, and so on in their advertising and sales methods. Psychologists often use a method called “behavior therapy(疗法)” to help individuals solve their personality problems. In the same way, they can help people who feel that they have problems with money.

    There's a new frontier in 3D printing that's beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. And the industry isn't stopping there.

Food production

    With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that — it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to "re-create forms and pieces" of food that are "exactly the same," freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.

Sustainability(可持续性）

    The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is becoming a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids (水解胶体) from plentiful renewables like algae(藻类) and grass to replace the familiar ingredients(烹饪原料). 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.

Nutrition

    Future 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, "Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday's bread from the supermarket, you'd eat something baked just for you on demand."

Challenges

    Despite recent advancements in 3D food printing, the industry has many challenges to overcome. Currently, most ingredients must be changed to a paste(糊状物) before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad. Some experts are skeptical about 3D food printers, believing they are better suited for fast food restaurants than homes and high-end restaurants.

    People You've Never Heard of Who Changed the World

    It is a fact that most people live their lives unremarked by history. Whether by design or by accident, there are some pioneers whose achievements changed the course of history but whose names are unknown to us.

    James Harrison

    James Harrison has saved the lives of over two million people by donating his blood 1,173 times, a Guinness world record. His blood produces a rare antibody (抗体) which cures the otherwise deadly Rhesus disease in unborn children. It has also been used in the development of a medicine anti-D, which will cure the Rhesus disease in children forever.

    Lewis Latimer

    After helping Alexander Graham Bell obtain his patent for the telephone, Lewis Latimer patented a carbon filament (碳灯丝), which allowed light bulbs to burn for hours before burning out, much more useful than that invented by Thomas Edison. Latimer went on to invent many other useful devices, including a device which cooled and cleaned patients' rooms in hospitals.

    Maurice Hilleman

    Not all achievements require bravery and self-sacrifice. Take Maurice Hilleman for example. He found another way to change the world. He developed the mumps vaccine (疫苗) after his daughter got the illness. And he didn't stop there. In total, he has single-handedly developed over 40 vaccines, including eight commonly given to children. His work has saved millions of lives and prevented serious consequences due to the diseases.

    Nils Bohlin

    In 1959 Nils Bohlin patented a revolutionary design that has saved millions of lives－the three-point safety belt. After the initial resistance from drivers who hated being told what to do, and even for their own good, the three-point belt has become a standard feature in new cars around the world.

Bogre Udell, who speaks four languages, met Frederico Andrade, who speaks five, at the Parsons New School in New York City.In 2014, they started a project to make the first public records of every language in the world.They've already recorded more than 350 languages, and plan to hit 1，000 in the coming years.

"When humans lose a language, we also lose greater diversity (多样化) in art and traditions，"said Bogre Udell.Between 1950 and 2010, 230 languages disappeared.Today, a third of the world's languages have fewer than 1，000 speakers left.Every two weeks a language dies with its last speaker, and 50 to 90 percent of them are said to disappear by the next century.

Wikitongues has asked for volunteers in 40 countries to film native speakers talking in the past, present，and future tenses of their mother languages.Native speakers are asked to recall childhood, share their stories, and discuss their hopes and goals.One volunteer in the South Pacific islands of Vanuatu recorded a language that had never been studied by language experts before.Another volunteer found a speaker of Ainu, a language in Japan that has no relation to any other known language, and he also recorded it.However, priceless recording opportunities disappear regularly.Not long ago, one of the last two speakers of a Saami language in the Russian steppes died right before his recording session with Wikitongues.

A lack of protection and globalization are responsible for diminishing language diversity.For much of the 20th century, governments across the world forced some local people to use official languages.More than 100 languages in Australia have disappeared since European settlers arrived.However, most languages die today because of other factors; climate change and urbanization contribute (是……的原因之一) greatly to the disappearance of languages.
