8 . Physicist and Nobel Prize winner Richard Feynman developed a clever learning method known as the Feynman Technique. It involves explaining what you're learning to others. By teaching what you’ve learned from memory, you engage in active recall.     1     It also ensures that you understand the topic, because you can only explain an idea if you truly understand it. The technique consists of four repeatable steps.

To begin, choose a concept or topic you wish to fully understand.     2     The more interested you are, the faster you’ll grasp it. Moreover, a personally interesting topic will keep you motivated and engaged.

    3     Write notes and explain it in a way that makes sense to a five-year-old. If you’d rather avoid actually teaching someone, you can just teach it to an imaginary audience. But it works much better if you use a real person. They’ll be able to let you know when something isn’t clear.

While teaching you may discover gaps in your understanding.     4     Review your notes, reread books, or seek external help to ensure you have a complete understanding of the context before moving forward.

Now that you fully grasp the concept, test your understanding by trying to teach it to another person. This will help you identify any remaining areas of uncertainty you need to revisit.

The Feynman Technique is a great way for kids and grown-ups to learn.     5     You need to actively think about the problem instead of passively reading or listening to someone else. However, with great efforts in mastering this method, you’ll see your learning results improve quicker than ever before.

A．It is mentally demanding.

B．This helps the information stick in your mind better.

C．Teach it to a five-year-old, who would give you direct feedback.

D．Your curiosity about it will determine the pace of your learning.

E．Once you have chosen a topic, you can teach it to someone else.

F．Active engagement plays a key role in promoting deeper learning.

G．When this happens, refer back to the original material for the missing pieces.

Now there is an increasing number of inactive people, namely the “mouse potato”. A mouse potato is someone who sits in front of his or her computer all day and eats junk food instead of regular meals. Why are we becoming potatoes and what can we do to avoid it?

One reason behind it is our modern way of life. We don’t have as much time to prepare and eat food as we used to.     1    Not all of these are bad for us, of course, but they make it more difficult for us to control what we eat.

If we want to be healthy, we should make good choices about what we eat.   It is not necessary to become a vegetarian, but we must make sure that our diet is varied and balanced. A healthy diet should give us the calories we need but not contain too much fat and sugar. The number of calories our body needs depends on what our body type is, how much we weigh and how active we are.

Teenagers need about 2,500 calories a day.    2    Getting the calories we need is not enough. If we want to be healthy, we must make sure that we get the calories in the best way possible. The best source for calories is carbohydrates, which are found in gains, vegetables and fruit. Our bodies store carbohydrates in our muscles so that we can get energy when we need it.

Junk food has a lot of calories but few nutrients, vitamins and minerals, Some food does have nutrients, for example pizza, but because it contains too many calories, it is still called junk food. A healthy diet should include a variety of food, most of which should be rich in nutrients.     3     Those of us who love French fries, sweets, ice cream and cheeseburgers can still enjoy an unhealthy bite every now and then. All we have to do is to be careful how often and how much we eat of it.

If we make the right choices about what we eat, we will be healthier and have more energy to enjoy the good things in life.     4    And remember, it is better to eat a potato than to be one.

A．Choosing what to eat is no longer as easy as it once was.

B．That does not mean that we are never allowed to eat junk food.

C．A balanced diet combined with exercise is the recipe for a healthy life.

D．Girls usually need a bit less and people who play sports may need more.

E．A large breakfast, one containing about 700 calories, will help lose weight.

F．Fast food restaurants are everywhere and supermarket shelves are filled with ready-made pre-prepared dishes.
