    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, a newspaper 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 amount will help, but a large number of carrots will not give you superhuman eyesight.

    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 (近视的), 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 from each other, especially green and red. Another commonly confused (困惑的) 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 happens.

    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.

Have you ever been to Ireland? If not, you should think of spending a vacation there. The Republic of Ireland stands in the south of the island. There are about 3, 470, 000 people in the country and the weather is quite wet but warm. Falls of snow in Ireland are most unusual. 

Ireland is full of interesting things to do. You'll find restaurants and café everywhere. Most of them have a long list(清单) of Irish food and drinks. After your meal, you can take a walk along the shore(岸). The countryside is good for horse riding. Other sports you may want to do are sailing, boating, swimming, fishing and golfing. Ireland is famous for its theaters and festivals. So, why don't you stay longer for a party or a concert? 

The Irish people are kind and friendly. From mountains to beaches you will find people ready to stop and talk about the weather, the local geography or history and maybe about what you should see next. The Irish people have kept their own culture of music and literature(文学) well. Different areas have different kinds of music. In towns and villages people get together in the evening to sing and play music. They also get together to read their own poems to each other. Meeting such people is really fun, isn't it?

Many people like collecting things.  For some people, they don't throw away the unwanted things because they believe they may be useful one day.  For others, especially old people, old things keep memories of the past and old friends.  They carry a special meaning.  Collecting things can easily become a hobby.  When people really put heart into it, the hobby can do them much good. 

Collecting makes people happy during their free time.  Collectors do not have to go outside for fun.  They keep collections at home: stamps, books, pictures, model cars, toy animals, etc.  It is always enjoyable to look at the collections. 

Collecting keeps people busy, too.  When there is a new piece of collection, they need to find the right place for it.  Sometimes this new piece pushes them to read.  In this way, collectors learn new things from the hobby. 

Collecting also gives people a reason to make new friends.  Collectors may want to meet other collectors to show new findings, to share stories, and to get advice.  So the hobby leads to travel.  Collectors take trips to meet new friends.  Their group of friends grows.  After years of sharing, collectors may become closer friends. 

Collecting things helps people make good use of their free time.  It brings collectors a busy but happy life.
