“I’ll finish my homework before playing video games.”

“Your dress looks beautiful.”

“I won’t spend all the money on snacks.”

All lies! Most of us have told a lie at one time or another. However, scientists found that lying can harm your brain(大脑). It may stop you from doing other important tasks.

When you tell the truth, your brain doesn’t have to do any extra (额外的) work. But lying takes much more work.

Imagine you’re late to class. The teacher asks why and you decide to lie. So you say: “I picked up a book from the library.” Your teacher asks, “The book I assigned (布置) last time?” Then you must decide how to answer the question. If you say yes, your brain works a lot more to keep the lie from falling apart.

You just gave your brain a lot of extra work. An area called the prefrontal cortex (前额皮质) does the work. It’s the part in charge of short memory. That area also takes care of planning, problem-solving and self-control.

Using too much brainpower to lie means there’s less available for other things-like solving math problems. Lying is even harder for young people. The prefrontal cortex is not fully developed until age 25. So when young people are busy with lying, they’ll have a harder time doing other things, like making study plans or eating a healthy diet. So think twice before lying next time!

Many of us don’t care about the importance of eye care. It is said that if you take care of your body, then you can surely be healthy. That is why we should give a lot of care to our eyes. Natural eye care should be in a number one place.

There are several causes leading to poor eyesight like not enough food, genes (基因) and aging (老化). Television, computers and reading are also the causes of having poor eyesight. If you have to work in front of the computer, it is best to take a rest every once in a while. Something dirty can cause redness and they will make you feel uncomfortable. It is bad for your eyes, too. If this happens, the best way is to clean your eyes by using cold water. You must also try your best to protect your eyes from harmful things. For example, sunglasses can not only make you look cool but they can also serve as a great way to protect your eyesight from UV rays.

Eating healthy foods will do good to your eyesight. Remember that vitamin A, C and E are good for your eyes. Try to eat food groups that have these vitamins. And you should do eye exercises because exercise protects your eyesight, too. If a person often exercises and eats the right kind of food, his eyes will stay in good health for a long time.

All above are natural ways of eye care that help us keep eyes healthy. Being happy all the time can be helpful to a person’s eyesight, too. In a word, eye care is very important, no matter how old a person is.
