Most people around the world are right-handed. This also seems to be true in history. In 1799, scientists studied works of art made at different times from 1,500 B.C. to the 1950s. Most of the people shown in these works are right-handed, so the scientists guessed that right-handedness has always been common through history. Today, only about 10% to 15% of the world's population is left-handed.

Why are there more right-handed people than left-handed ones? Scientists now know that a person's two hands each have their own jobs. For most people, the left hand is used to find things or hold things. The right hand is used to work with things. This is because of the different work of the two sides of the brain. The right side of the brain, which makes a person's hands and eyes work together, controls the left hand. The left side of the brain, which controls the right hand, is the centre for thinking and doing problems. These findings show that more artists should be left-handed, and studies have found that left-handedness is twice as common among artists as among people in other jobs.

No one really knows what makes a person become right-handed instead of left-handed. Scientists have found that almost 40% of the people become left-handed because their main brain is damaged when they are born. However, this doesn't happen to everyone, so scientists guess there must be another reason why people become left-handed. One idea is that people usually get right-handed from their parents. If a person does not receive the gene (基因) for right-handedness, he / she may become either right-handed or left-handed according to the chance and the people they work or live with.

Though right-handedness is more common than left-handedness, people no longer think left-handed people are strange or unusual. A long time ago, left-handed children were made to use their right hands like other children, but today they don't have to.

Chongyang Festival {#blank#}1{#/blank#} (celebrate) on the ninth day of the ninth month on the traditional Chinese calendar, and it is also known as Double Ninth Festival.

In Chinese culture, the number nine is thought to be yang. The ninth day of the ninth month is a double yang day and "double"{#blank#}2{#/blank#} (mean) Chong in Chinese, so it got the name Chongyang Festival. The ninth month also heralds（预示）the coming of winter, so it is a time when the living need warm clothes, and some people make the festival a time for {#blank#}3{#/blank#} (provide) special clothes for their ancestors（祖先）.

During the festival, people usually {#blank#}4{#/blank#} (climb) mountains, wear the zhuyu plant, drink chrysanthemum (菊花) wine, and eat Chongyang cake. Cake in Chinese is pronounced "gao" meaning high, so people consider climbing a high mountain to be the same as eating cake. Also, people think they {#blank#}5{#/blank#} (do) better than before after eating the cake.

Double Ninth Festival is also Seniors' Day— a day to care for the elder people and to let them {#blank#}6{#/blank#} (enjoy) themselves. On the day, many communities organize retired people to go out {#blank#}7{#/blank#} (climb) mountains.

Money may not buy happiness, but it helps.Many teenagers want to learn how to manage money before going out into the world. {#blank#}1{#/blank#} This idea is raised by Dr Mara Harvey, a money expert. The following are some of her tips.

Learn to make money. Ask parents or neighbours if you can do chores to make pocket money.These could include washing a car or taking the dog for a walk.{#blank#}2{#/blank#} In this way, you can also improve your communication skills, which will help when you have a grown-up job, too.

Help your money grow. Money can't grow if it's sitting inside a piggy bank. Put your money in the bank and you can get interest(利息). {#blank#}3{#/blank#}One day you may feel surprised at how much money you have.

Make a plan. If you have a big event, such as a holiday coming up, it might mean you will need to spend more of your pocket money. Try making a plan for spending and saving. {#blank#}4{#/blank#} Then it will help you take control of your money.

{#blank#}5{#/blank#} Figure out how much you can reasonably spend each month. Spend your money on what you truly need. Then try to cut down on spending. For example, rather than eating out,you can choose to cook at home.
