As a father who works outside the home, I recognize that it is easy for me to get caught up in stress at work. Indeed, sometimes it is difficult to turn off my work focus and turn on my family focus so that I can come home and be the loving husband my wife needs and the playful father my kids want. {#blank#}1{#/blank#} Good fathers provide stability and strength to the family. As fathers, we do not let the pressures and worries of work get in the way of being there for our kids. {#blank#}2{#/blank#}

1）．{#blank#}3{#/blank#} It doesn't need to be a lot of time, but if you are able, have one­on­one time with each of your kids.

Be an inventor

    The biggest secret about inventing is that anybody can do it! Perhaps this sounds crazy, but it's true. Maybe you have the wrong idea about inventing, so read on to discover the truth.

Wrong idea number 1:{#blank#}1{#/blank#}

    Well, inventing means creating something “new”, but the idea could come from something that already exists.{#blank#}2{#/blank#} 

Wrong idea number 2: Inventors are born, not made.

    There are a lot of factors that make invention possible. Take Mozart, for example. He was born with a special talent for music.{#blank#}3{#/blank#}His father was a music teacher, and Mozart practiced for hours every day, from the time he was in kindergarten.

    {#blank#}4{#/blank#}Very successful creators don't give up when they get something wrong. As one inventor said, “A failure is the right answer to the wrong question!”

    Wrong idea number 3: Inventors are always old people.

{#blank#}5{#/blank#} Here is an example of a young inventor: Louis Braille went blind when he was a child. When he was 15, he invented a system of reading and writing for blind people that is still used in most countries today.

A. Everyday things can give people lots of ideas.

B. An invention has to be something completely new.

C. But other factors were also important for his creativity.

D. As a young man, George Nissen invented the trampoline (蹦床).

E. Don't believe that you can't invent something when you are young.

F. Thomas Edison said that being an inventor was “99% hard work and 1% inspiration”!

G. The Wright brothers, for example, got the idea for building a “flying machine” from watching birds.

    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.

    Good learners can inspire students or anybody to learn well. Here are some characteristics of good learners.

    Good learners are curious. They wonder about all sorts of things, often about knowledge beyond their areas of expertise(专长). {#blank#}1{#/blank#} Finding out about something they didn't know satisfies them for the moment, but their curiosity is addictive.

    Good learners don't give up easily. A few things may come easily to learners but most knowledge arrives after effort. {#blank#}2{#/blank#} They try to search out new information. They read, analyze, and evaluate the information they've found. Then they study more and work at what they don't understand.

    Good learners know that a lot of learning isn't fun. The journey to understanding generally isn't all that exciting. {#blank#}3{#/blank#} Others need a tiresome attention to detail, and still others need periods of intense mental focus. Your backs hurt, your arms and legs get tired, and your coffee gets cold.

    {#blank#}4{#/blank#}There's always more to know. Good learners are never satisfied with how much they know about anything. They are pulled around by questions—the ones they still can't answer, or the ones without very good answers. Those questions follow them like day follows night with the answers bringing daylight.

    Good learners share what they've learned. Good learners are teachers committed to sharing with others what they've learned. {#blank#}5{#/blank#} Good learners can also explain what they know in ways that make sense to others. They are connected to the knowledge passed on to them and committed to leaving what they've learned with others.

A. Some learning tasks require boring repetition.

B. Good learners are willing to put in the time.

C. Some knowledge can broaden our views.

D. Good learners stay positive.

E. They write about it, and talk about it.

F. They love the discovery part of learning.

G. Good learners never run out of questions.

    Summer is the perfect time to relax. As you plan for your trip, here are some tips on how to protect yourself. {#blank#}1{#/blank#}.

    Fight against the mosquitoes in the hot spots.

    There are many mosquito-borne illnesses in tropical regions, which are traditionally vacation hot spots. Therefore, mosquito repellent (驱蚊剂) that contains DEET should be an essential item in your travel bag.

    {#blank#}2{#/blank#}.

    In lesser-developed countries there is less equipment for clean water and public health. If you can't avoid unhealthful water, make sure you bring along a tea or coffee—making pot that will boil water for you. You'd better buy a case or two of water and check that all bottle caps are sealed to assure the bottled water isn't just a refilled bottle of dirty tap water.

    Always protect your feet.

    It's best to wear slippers in the shower, but if you must be barefoot, put a towel down on the floor. {#blank#}3{#/blank#}. You should never walk barefoot in any area of a foreign country, including your hotel room.

    Be sure to eat safe fruits.

    {#blank#}4{#/blank#}. They may have been washed in the same water, or wiped with the same rag used to clean work surfaces in kitchens. The best advice is to bring your own peeler（削皮器）so that you know that something clean has been applied to the fruit.

    Enjoy the smell of roadside stands, not the food.

    Unless the food is piping hot when served, it's best to stay away from roadside stands, no matter how good the smell of the food might be. If you are concerned about whether a restaurant is clean, order the food to go. {#blank#}5{#/blank#}.

    Futurologists (未来学家) predict that life will probably be very different in 2050.

    TV channels will have disappeared. {#blank#}1{#/blank#} Today, we can use the World Wide Web to read newspaper stories and see pictures on a computer thousands of kilometers away. By 2050, music, films, programs, newspapers and books will come to us by computer.

    {#blank#}2{#/blank#} Cars will have computers to control the speed and there won't be any accidents. Today, many cars have computers that tell drivers exactly where they are. By 2050, the computer will control the car and drive it to your destination.

    {#blank#}3{#/blank#} Many factories already use robots. Big companies prefer robots—they don't ask for pay rises or go on strike, and they work 24 hours a day. By 2050, we will see robots everywhere—in factories, schools, offices, hospitals, shops and homes.

    {#blank#}4{#/blank#} Today, there are devices (设备) that connect directly to the brain to help people hear. By 2050, we will be able to help blind and deaf people to see and hear again with the help of new technology.

    Scientists will have discovered how to control genes. {#blank#}5{#/blank#} By 2050, scientists will be able to produce clones of people, and decide how they look, how they behave and how clever they are. Scientists will be able to do these things, but should they?
