    What do the world's most successful people all have in common?

By examining the work habits of over 150 greatest writers and artists and scientists, the researchers including Stanford professor Jeffrey Pfeiffer found that high achievers like Robert Moses turned out to be all alike: 

Busy! Busy!

    {#blank#}1{#/blank#} In a study of general managers in industry, John Kotter reports that many of them work 60 to 65 hours per week—which translates into at least six 10-hour days. The ability and willingness to work difficult and tiring hours has characterized many powerful figures. Energy and strength provide many advantages to those seeking to build power.

Just Say No!

    The difference between successful people and very successful people is that very successful people say “no” to almost everything. And that's what gives them the time to accomplish so much.{#blank#}2{#/blank#} And focus means saying “no” to a lot of distractions (分神).

{#blank#}3{#/blank#}

    Ignore your weaknesses and keep improving your strengths. Don't waste time exploring skill areas where you have little competence. Instead, focus on—and build on—your strengths. This means knowing who you are, what you are and what you are good at.

Create Good Luck！

    {#blank#}4{#/blank#} There's a science to it. Richard Wiseman studies lucky people for his book Luck Factor, and breaks down what they do right. Certain personality types are luckier because they behave in a way that offers the chance for good opportunities. By being more outgoing, open to new ideas, following the feeling that something is true, and being optimistic, lucky people create possibilities.

    Does applying these principles to your life actually work? Wiseman created a “luck school” to test the ideas—and it was a success. In total, 80 percent of the people who attended Luck School said that their luck had increased.{#blank#}5{#/blank#}

A. Spend enough time to improve your weakness.

B. Achievement requires focus.

C. On average, these people reported that their luck had increased by more than 40 percent.

D. They never stop working and they never lose a minute.

E. Busy people are more likely to be lucky.

F. Know What You Are!

G. Luck isn't magical.

    Now, if you want to be charming, then you'll need to build self-confidence, but becoming more outgoing is actually pretty easy. To get to a point at which you feel comfortable talking to complete stranger, follow these steps.

    Encourage your curiosity about people{#blank#}1{#/blank#}I wonder what his parents look like. I wonder what her favorite color is. Is he from around here? Is she the girl I saw at the movie theater last week? It will take some conscious effort, but you can't be outgoing if you don't care about people.

Smile at others. Make it a goal to smile at one person a day. It can be anybody, and it can be the most subtle(微妙的) of smile. A quick glance paired with a smile—then run away if you want!{#blank#}2{#/blank#}Eventually, you will want to get to a point where you smile instinctively whenever you make first eye contact with someone.

    Ask people questions. The standard ”how are you?” doesn't really count, because people use it as a greeting rather than a real question{#blank#}3{#/blank#}This is where the curiosity and interest in others come into play.

    {#blank#}4{#/blank#}This is key to being a good conversationalist. If you don't make enough eye contact, the other person will feel invisible and the sense that you're elsewhere mentally. If you make too much, they'll feel uncomfortable. Is that specific enough for you?

    Note your body language{#blank#}5{#/blank#}To show that you're outgoing and welcome conversations, keep your body open, you head up, and a smile on your face. Resist playing with your phone or otherwise occupying yourself.

A. Master eye contact.

B. Never hesitate to smile at others.

C. Most of communication isn't verbal.

D. The more you do it, though, the less scary it will be.

E. Make eye contact when you're asking questions about people.

F. Wherever you go, try to observe people, and ask questions about them.

G. If you've already exchanged eye contact and smiles with someone, start off with a question,

Plan a Budget-Friendly Summer Vacation

    It's never too early to start thinking about your summer vacation. Deciding where to go and what attractions to see can actually be a fun and exciting part of the experience—particularly when you find ways to save your travel dollar. {#blank#}1{#/blank#}

    Rethink your “summer vacation”.

    If your summer vacation window is wide open, why not skip July and August? The flights and accommodations are about 25% cheaper in the spring or early fall. If you must travel during the busy season, you can still save by being flexible. {#blank#}2{#/blank#} Flying out on a Tuesday instead of a Friday could save you a bit of money, and flying in the afternoon will likely be cheaper than a morning flight.

    {#blank#}3{#/blank#}

    It's always in your best interest to book your summer vacation early. If you plan on flying to your destination, for example, it will be much easier to find seats on your preferred flights if you book in March than if you were to wait until the last minute. The same applies to hotels, where prices are based on supply and demand.

    Use the right websites.

    There are a lot of websites competing for your travel dollar. {#blank#}4{#/blank#} For example, when you make five reservations with Booking.com, you can have access to their “Genius Program” which gives you 10% off as well as early check-in and late check-out.

    Consider a tour.

    With so many places to see and things to do, planning a trip can wear you out quickly. {#blank#}5{#/blank#} Seasoned tour operators, such as Trafalgar, take the stress out of travel so all you have to do is show up and enjoy yourself. More importantly, a guided vacation represents a significant saving.

    Do you know that 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. {#blank#}1{#/blank#}

    Food production

    With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. {#blank#}2{#/blank#} —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

    According to a new study, 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. {#blank#}3{#/blank#} 3D food printing could probably contribute to the solution. 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

    {#blank#}4{#/blank#} 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."

    {#blank#}5{#/blank#}

    Despite recent advancements in 3D food printing, the industry has many difficulties 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.

A. Challenges

B. Opportunities

C. And the industry isn't stopping there.

D. Sustainability is becoming a necessity.

E. Future 3D food printers could make processed food healthier.

F. Here are some new ways to produce 3D printing.

G. Not everybody can do that.

    Nowadays people tend to digitalise everything from watches to fridges. It seems you can choose any item labeled as “smart”.{#blank#}1{#/blank#}However, there are plenty that can be used to reduce emissions and save money.

    If you're a part of the digitalisation movement, you might be interested in the concept of smart homes. It means that every element of your house can be controlled from a panel on the wall or your phone.{#blank#}2{#/blank#}Use your mobile to power them on or off, and you may feel truly modern or truly lazy. Asides from the benefits of living a more comfortable life, this presents an opportunity to cut down on your electrical bills.

    Electricity generation today represents 31% of total global fossil fuel use and around 40% of all energy-related CO₂ emissions.{#blank#}3{#/blank#}It is considered as the first step to prevent global climate change. Connect a smart thermometer to the heating and cooling system and set a specific temperature at which the heating begins to work. Doing so, the room will be at a desired temperature when necessary and switches on a power-saving mode when not occupied. Similarly, by installing a CO₂ sensor, you can have an automated ventilation (通风) system.{#blank#}4{#/blank#}

    In a 150,000m₂ office complex near Munich, called Campeon, energy costs of up to 117,067 Euro were saved after the use of environmental control devices this year. In this way, they are contributing to a large decrease in CO₂ emissions. Clearly, smart homes are about much more than just living a comfortable life.{#blank#}5{#/blank#}

A. It is actually about living a green life.

B. Smart devices have been installed worldwide nowadays.

C. It starts working only when CO₂ concentrations reach a certain limit.

D. There seem to be an ocean of such so-called “smart” inventions.

E. Bearing this in mind, measures should be taken to make buildings more energy-efficient.

F. Alternative energy must be discovered before the fossil fuel runs out in the future.

G. This includes basics such as heating and lighting and many other appliances.
