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.

    Most of us will admit that on occasions we can be bad－tempered. This can be for a number of reasons.

    {#blank#}1{#/blank#}As the body and mind are tired, it seems to take us less time to become angry just because of something that is of little importance. Young children are usually the cause of tiredness and it is highly likely that parents allow themselves to release(释放) their exhaustion directly at the children. Children are very good at remembering these instances and it will affect them for a long time.{#blank#}2{#/blank#}

    Diet and lifestyle can be key factors in causing a bad temper. Some people don't realize that their diet can directly affect their moods. Processed food and items that contain a lot of sugars, especially those that aren't natural sugars, can cause a rise in blood sugar. {#blank#}3{#/blank#}Similarly, lifestyle choices can encourage bad tempers and poor moods, especially if drug and alcohol are used too frequently.{#blank#}4{#/blank#}

    If you have noticed that you are becoming increasingly bad－tempered, it is important that you take steps to try and regain control. {#blank#}5{#/blank#}After you find the cause, try and make positive changes to prevent this from occurring in the future.

A. Find your ways to release your anger.

B. Check what it is that causes the bad mood.

C. Tiredness is often the most common reason.

D. Managing your anger is good for your health.

E. Therefore, it is important to have more patience when with children.

F. This rise can have a very negative effect on moods and mental performance.

G. So it is important to keep away from these temptations(诱惑) for your own mental state.

    Recently, I've been following a simple rule that is helping me crush procrastination(拖延症) and making it easier for me to stick to good habits at the same time. {#blank#}1{#/blank#} There are two parts to the 2-Minute Rule.

    Part 1­If it takes less than two minutes, then do it now.

    {#blank#}2{#/blank#} For example, washing your dishes immediately after your meal, tossing the laundry in the washing machine, taking out the garbage, sending that email, and so on.

    If a task takes less than two minutes to complete, then follow the rule and do it right now.

    Part 2­When you start a new habit, it should take less than two minutes to do.

    Can all of your goals be accomplished in less than two minutes? Obviously not. But, every goal can be started in 2 minutes or less. {#blank#}3{#/blank#} It might sound like this strategy is too basic for grand life goals, but I beg to differ. The 2-Minute Rule works for big goals as well as small goals because of the inertia(惯性)of life. {#blank#}4{#/blank#}  I love the 2-Minute Rule because it embraces the idea that all sorts of good things happen once you get started.

    The most important part of any new habit is getting started­not just the first time, but each time. It's not about performance, it's about consistently taking action.

    I can't guarantee whether or not the 2-Minute Rule will work for you. {#blank#}5{#/blank#}  Anyone can spare the next 120 seconds. Use this time to get one thing done. Go.

A. I call this little strategy the "2-Minute Rule".

B. And that's the purpose behind this little rule.

C. Here's what you need to know to stop procrastinating.

D. Once you start doing something, it's easier to continue doing it.

E. But, I can guarantee that it will never work if you never try it.

F. The goal is to make it easier for you to get started on the things you should be doing.

G. It's surprising how many things we put off that we could get done in two minutes or less.

To help you understand what 5G is, and what it means to you, we've put together a handy guide here.

What is 5G?

{#blank#}1{#/blank#}At its most basic level, 5G will be used to make calls, send texts, and to simply get online. But it's going to be significantly faster than previous generations, and could open the door up to a range of exciting new uses.

    {#blank#}2{#/blank#}

5G will use new higher radio frequencies to send out data, which are less cluttered(挤了)and carry information much faster. While these higher bands are faster, they don't carry information as far. That's to say, smaller multiple input and output antennas (天线)will be used—promoting both signals and capacity（容量）.

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

Why is it better than 4G?

5G is expected to be faster than 4G, with some firms claiming it could be as much as 100 times quicker. The fastest 4G networks can deliver peak download speeds of around 300 Mbit/s. {#blank#}4{#/blank#}In real life, this could allow you to download a full HD film in less than 10 seconds!

    {#blank#}5{#/blank#} It means there will be very little—if any—delay when you carry out tasks on a device. While this will help improve things like gaming experiences, it could also pave the way for safer self-driving cars—in which even a short delay could be life-saving.

Finally, 5G will have a larger capacity, meaning networks will be able to deal with several apps at once. Generally, this should mean that devices have a faster, more stable connection.

A. How does 5G work?

B. How will 5G affect you?

C. 5G is also expected to have a lower latency （潜在因素）.

D. 5G is short for "5th generation mobile network."

E. In comparison, 5G could offer download speeds of over 1 Gb/s.

F. Therefore, the similarity between 5G and 4G technology is huge.

G. This means 5G will support up to 1,000 more devices per meter than 4G.

Starting a club of some kind at school can be difficult. But with a good idea, some active friends, and the right knowledge, you can pull it off. {#blank#}1{#/blank#}.

Decide whether you really want to start a club. Once you have strong enough support from your friends and fellow students, you're ready to go.

{#blank#}2{#/blank#}. Find an advisor for your club. Pick someone who will help you organize events for your club.

Find a place. {#blank#}3{#/blank#} If you want to do this,  talk to your headteacher to apply (申请) for a classroom.

Decide when to meet. Decide how often your club should meet, and then pick a convenient time and day when most club members will be free.

Advertise your club at school. Make bright, colorful informative posters (海报) that will attract attention. {#blank#}4{#/blank#}.

Plan volunteering events. You can decide on events yourself, or hold a meeting to get your club's opinion. {#blank#}5{#/blank#}

Have fun. What's the point of having a club if it's no fun? Don't take yourself too seriously and be sure to have a sense of humor.
 

When something goes wrong, do you tend to bounce back or fall apart? Here are some strategics to help you manage a personal setback(挫折)and get back on track toward achieving your goal.

● Realize it's normal. Less than 20 percent of people successfully achieve their goal the first time around. It's normal and expected for setbacks to occur.{#blank#}1{#/blank#}Knowing this, it's important to anticipate that the main task will be how to effectively manage the setback when it arises.

● Don't deny it. Sometimes it's hard to recognize a setback. The problem can be staring at you right in the face, but you may deny there's any cause for alarm.{#blank#}2{#/blank#}This inability to acknowledge the problem doesn't mean you're stupid. It's just that denial can cloud your awareness of the issue. It's important to be receptive to the honest feedback.

{#blank#}3{#/blank#}Stop and consider carefully what went wrong. The most common causes of a setback are personal worries, overconfidence, and poor coping skills. Take a look at any factor that may have contributed to the setback: where you were, who you were with, what you were thinking and feeling.

● Learn from it. Learn from your analysis of the setback, and adjust your plan to try to prevent similar things from happening the next time. Each time you fine-tune your plan and put it into action again, you actually improve your odds of eventual success.{#blank#}4{#/blank#}

Remind yourself that your setback is a slip instead of a fall.{#blank#}5{#/blank#}After adjusting, you can still make progress toward success again.

A.Don't take it seriously.

B.Analyze what happened.

C.You haven't lost all of the knowledge, skills, and support.

D.In other words, it's not whether a challenge will happen, but it's when.

E.This is because you learn from each misstep to make your plan more effective.

F.Friends or family will voice their concerns, but you still may not be able to accept it.

G.You might even write about past experiences in a journal to guide your future behavior.
