When are they going to meet at the gate of the library tomorrow?

A.At 8:00. B.At 8:15. C.At 8:45.

When we wake up feeling sleepy and with dark circles under eyes, many of us often think "I'm going to go to bed earlier tomorrow!" But however determined (有决心的) we are. Chances are that we don't stick to our promise.

This behavior is called "bedtime procrastination (拖延症) , and results from lack of (缺乏) self-control and our body clock. Reported Huffpost.

According to a study carried out by a group of health psychologists at Utrecht University in the Netherlands (荷兰)in 2014, bedtime procrastination is a common problem. In their study, 53 percent of the2, 400participants (参与者)said they didn't follow their sleep schedule (日程) , delaying (延迟) it at last twice a week.

It's found that they delayed bedtime not because they liked to stay up late, but they couldn't stop doing other trivial (琐碎的) things, which were keeping them up in he first place.

"People who generally have trouble fighting against temptations (诱惑) and sticking to their intentions (意图) are also more likely to delay going to bed, "Floor Kroese, a psychologist at Utrecht University, further explained to HuffPost.

Yet, according to scientists, lack of self-control is not the only thing to blame (责备) . Our body clock also plays an important role when it comes to bedtime.

In order to check the influence of the body clock on sleep, psychologists at Um University in Germany studied the sleep patterns (模式)of 108 people in February. It was found that those who get up late are more likely to postpone their bedtime than those who wake early every morning.

And more surprisingly, night owls (夜猫子) would go to bed late at the very beginning of the weekday, even though they had to get up early for work and school. It's their special body cock that plays a part in delaying their bedtime, reported Popular Science.

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 (波长)of light. If these cells don’t work properly, color blindness occurs.
