Has anyone ever told you that eating carrots will help you see in the dark? This is just one of many incorrect beliefs you may have heard. Below, TEENS has picked out scientific explanations for three mistakes that people make about their eyes. Let's take a look.

Can eating carrots improve your eyesight?

Carrots are rich in vitamin A, which helps the eyes to turn light into information for your brain. This allows people to see in darker places. However, eating more carrots won't help you see better. A certain minimum amount will help, but a large number of carrots will not give you superhuman vision.

If your parents have bad eyesight, will you have bad eyesight, too?

Myopia( 近 视 ) can be passed from parents to children. A study by the American Optometric Association found that if both parents are myopic, there's a 33 to 60 percent chance that their child will be. For children who have one parent with myopia, the chance is 23 to 40 percent, and it's down to 6 to 15 percent for kids with non-myopic parents. So if your eyesight is bad, your children might still have good vision.

Do color blind people see the world in black and white?

Color blindness doesn't usually mean that people see the world like an old movie. They usually can't tell certain colors apart, especially green and red. Another commonly confused pair of colors is yellow and blue. Our eyes have cone cells (视锥细胞) that sense different wavelengths of light. If these cells don't work properly, color blindness occurs. There are different levels of color blindness. Some people are only color blind in low light. However, in the most serious form of color blindness, everything is shades of gray.

1.According to the article, eating carrots________.

A.stops the brain from seeing B.doesn't help you see better at all

C.will help you see clearly in the dark D.is good for your eyes to some degree

2.If both parents have myopia, their child's chance of having good eyesight is________.

A.40-67% B.33-60% C.23-40% D.6-15%

3.The underline word“occurs”in this passage probably means________.

A.恶化 B.发生 C.改善 D.加深

4.What is the cause of color blindness according to the text?

A.Watching movies for too long . B.Getting too little exercise.

C.Cone cells not working properly. D.Changes in the wavelength of light.

5.What is the purpose of the article?

A.To offer some advice on protecting your eyes.

B.To clear up some misunderstandings about our eyes.

Life is competitive - some kids can do something faster or better than other kids. This might not seem fair, but all people are different and how well you can do something is different to others. This means there are “winners" and “losers", and lots of people are neither winners nor losers but in-between. You can choose to be a good winner or an even better loser whether you are competing against others or yourself.

Being a “good” winner

No one likes a “show off”.

No one likes someone who takes all the praise for the efforts of a team.

No one likes people who put others down to make themselves look good.

To be a good winner you need to:

◆Be modest(谦虚的).

◆ Thank those who helped you for their efforts.

◆ Keep trying to improve your skills.

◆Aim for the next step up in whatever you are doing well.

Being an even better loser

Of course it’s disappointing to lose, especially if you are close to winning. Behaving badly or angrily, name-calling and going on about things being “unfair” won’t change the final result and will only make you look like a bad sport. And no one likes bad sports either.

To be an even better loser you need to :

◆ Behave politely, nicely and kindly.

◆ Congratulate the other team.

◆ Keep any negative (消极的) thoughts to yourself - at least until you are away from the game.

It’s Ok to let out your negative thoughts to your best friend or parents later. And if you don’t do very well in a game, try harder to learn for the next one. Improving yourself makes you a winner too.

1.What can we learn from the first paragraph?

A.We are either losers or winners.

B.We should face winning and losing properly.

C.We can do nothing about winning and losing.

D.We are always competing with others not ourselves.

2.What should a better loser do when losing?

A.Let out his anger to his parents at once.

B.Express his negative feelings in the game.

C.Try harder to improve himself in the next game.

D.Behave badly to his team members or competitors.

3.Which one is not proper if we succeed?

A.Going on improving our skills.

B.Telling our team members to aim higher.

C.Thanking our team members for their efforts.

D.Putting down others to make ourselves look good.

4.Who is probably a bad sport?

A.Tom keeps saying the game is unfair when he loses.

B.Jim encourages his teammates after their team loses.

C.Anna thanks her coach for what he has done though she fails.

D.Cindy shows her congratulations to other competitors even if she fails.

5.What is the passage written for?

A.Telling us what we can learn from losing.

B.Offering advice on what we can do to win.

C.Encouraging us to become a winner instead of a loser.

D.Giving advice on how to deal with winning and losing.

As we all face the novel coronavirus, protecting yourself is the same as protecting others. Here are some safety suggestions.

Stay away from crowds and wear masks（口罩）

如果你不得不去拥挤的地方，记得戴口罩。Keep at least one metre between yourself and other people, particularly those who are coughing or sneezing.

Why? The droplets （粘液飞沫）can be transmitted farther by sneezing or coughing than by speaking. If you are too close, you can breathe in the virus （病毒）. Wearing a mask can stop droplets from reaching your face or mouth.

Keep proper indoor ventilation （通风）

Keep proper indoor ventilation while at home. Open windows to let in fresh air during the day. It's best to do this three times a day for 15 minutes to half an hour each time.

Why? The virus can only infect （感染）you when it builds up to a certain amount. Proper ventilation can stop the virus from gathering into a larger amount.

Keep up good habits

Keep healthy habits such as eating healthily and exercising regularly, as well as getting enough sleep.

Why? Doing these things can strengthen your immune system, making it less likely for you to become infected.

Wash hands properly

Remember to wash your hands before eating, after going to the bathroom, coming home, coming into contact with rubbish and touching animals. Avoid touching your eyes, nose and mouth before washing your hands.

Why? Your hands might touch surfaces with the virus. Washing your hands in time can stop the virus from entering your body.
