A strong memory depends on the health and vitality （活力） of your brain. They say that you can't teach an old dog new tricks, but when it comes to the brain, scientists have discovered that this old saying simply isn't true. {#blank#}1{#/blank#}

      Give your brain a workout. Memory, like muscular strength, requires you to “use it or lose it”. The more you work out your brain, the better you'll be able to process and remember information.{#blank#}2{#/blank#}

        Don't skip the physical exercise. While mental exercise is important forbrain health, that doesn't mean you never need to break a sweat. Physical exercise helps your brainstay sharp. It increases oxygen to your brain and reduces the risk for disorders that lead to memory loss.

        Get enough sleep. There is a big difference between the amount of sleep you can get by on and the amount you need to function at your best.{#blank#}3{#/blank#}Keep stress in check. Stress is one of the brain's worst enemies. Over time, stress destroys braincells. Studies have also linked stress to memory loss.

        Have a laugh.{#blank#}4{#/blank#} That holds true for the brain and the memory, as well as the body. Unlike emotional responses, which are limited to specificareas of the brain, laughter engages multiple regions across the whole brain.

{#blank#}5{#/blank#}Just as the body needs fuel, so does the brain. You probably already know that a diet based on fruits, vegetables, whole grains, “healthy”fats and lean protein will provide lots of health benefits, but such a diet can also improve memory. For brain health, though, it's not just what you eat—it's also what you don't eat.

A. Eat a brain-boosting diet.

B. Play games with memory.

C. Laughter is the best medicine.

D. But oversleeping is not good for yourbrain.

E. Even skipping a few hours makes adifference!

F. You have to shake things up from timeto time!

G. The human brain has an astonishingability to adapt and change.

    There are some popular family videos posted on Chinese social media. In these videos, a young child calls out to their mother or father; the parent enters the room smiling, turns around and calls out to their own parent; the grandparent then enters smiling and calls out to their parent – the great-grandparent.

    The format of these videos is being described as the "four-generation challenge". {#blank#}1{#/blank#} People from all over the world have left comments and even made their own versions.

    A Facebook user named Antoine Yupud wrote, "I have to give that to China. {#blank#}2{#/blank#}." The "four-generation" videos have not only touched foreign viewers, but also given them a deeper look into Chinese family values.

    In most East Asian cultures, it is common for many generations of a single family to live together under one roof. {#blank#}3{#/blank#}. Many Western countries tend to have nuclear families, made up of just children and their parents.

    {#blank#}4{#/blank#}. Kids usually move out of the family home after turning 18. Many apply for loans and work part-time jobs to pay for college and rent. If they choose to continue living with their parents after becoming an adult, it can be seen as a sign of immaturity or failure.

With the majority of children not going into school at the moment, staff, parents and pupils are pulling together to make sure their education is a success. As a teacher, I'd like to give some tips to parents and pupils on remote learning.

FOR PUPILS

Get online, on time.

Make sure you do log on in good time for the beginning or live lessons, rather than joining the lesson ten minutes in.{#blank#}1{#/blank#}

Play your part.

Contribute to the lesson. Talk, put your hand up, send messages in the chat whatever they might be. Teachers and other pupils love to see that. And don't be afraid to ask questions.

Take proper screen breaks during the day.

Enjoy your break time.{#blank#}2{#/blank#}Get outside, read a book, phone someone. At break or lunchtime in school you wouldn't sit in a classroom and continue to work, so you shouldn't do it at home either.

FOR PARENTS

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

It's often surprising how technologically able a young child is now, with the world of smart phones and the Internet. So let them show you what they need to be doing in class.

Give praise.

{#blank#}4{#/blank#} Now online, we share a lot of praise and give out school awards. They also need to be praised at home for getting their work done. Take a look at what they have been doing.

Get involved if you can.

This might be difficult for parents doing full-time jobs, but try to work together on something. We assign students research projects some of which might be challenging to them.{#blank#}5{#/blank#} And it's also good for their own well-being getting away from a laptop to make a cardboard castle or whatever it might be.

A. Let the child take the lead.

B. Keep pace with technology.

C. Don't stay sitting at your computer.

D. That's a perfect opportunity for parents to help.

E. Thus you will find the rest of the class challenging.

F. Otherwise you would have missed out on some teaching

G. At school kids are getting approval for the work they are doing well.

When it comes to helping students learn and mature, there are several ways to increase their well-being. Although your children may be succeeding in the classroom, there are a few things that you still can do.

Encouraging physical activity is the first thing you can do. More and more children do not participate in sports after school. It's important for you to encourage mobility with sports played after class. You should find sports equipment, basketball courts and play areas where kids can increase their well-being. {#blank#}1{#/blank#}

Secondly, you can provide proper nutrition for your children. It's important for your children to receive proper nutrition both inside and outside of the home. {#blank#}2{#/blank#}You'd better make it a point to provide enough nutrition for their proper development and growth.

{#blank#}3{#/blank#}Many parents fail to stop children from using smartphones and computers. There are some institutions that even encourage too much screen time as a way to teach children or keep them entertained. You should help the children remain excited without sitting in front of a screen throughout the day.

Last but not least, monitoring bullying(欺凌) is also an essential part. Bullying continues to remain a common problem in some schools, making it important that the environment that your children grow in holds a high standard.{#blank#}4{#/blank#}

It's important to examine the school life as a whole to determine what factors are missing. {#blank#}5{#/blank#}You may determine how well they adjust to the world around them and succeed in life.

A. You should provide kids with fresh food.

B. Besides, you'd better limit their screen time.

C. It will encourage children to focus on their study.

D. In addition, try your best to give them more freedom.

E. This will reduce the risk of health conditions that include obesity.

F. You can advise teachers to keep a practice of looking for bullying.

G. Parents play a significant role in children's growth and well-being.
