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.

People eat rice all over the world

Rice is believed to {#blank#}1{#/blank#}(grow) in China or possibly somewhere else in eastern Asia for about 10,000 years. The earliest evidence of rice farming comes from {#blank#}2{#/blank#} 7,000-year-old site near the lower Yangtze River village of Hemudu in Zhejiang province in China.

Rice is a kind of food which requires much labor. In {#blank#}3{#/blank#}(develop) countries, the planting and harvesting is done mostly with machines. However, in much of the world, these things are still largely done {#blank#}4{#/blank#} hand. It takes one farmer 1,000 to 2,000 working hours {#blank#}5{#/blank#}(raise) a rice crop on 2.5 acres of land. The fact that rice needs so much labor means {#blank#}6{#/blank#}(keep) a lot of the population on the land.

Rice is {#blank#}7{#/blank#}(certain) a crop in need of lots of water. The wet rice grown in most of Asia needs hot weather after a period of rain and conditions provided by the Asian rainy seasons affect many places {#blank#}8{#/blank#} rice is grown.

Rice straws (稻秆) {#blank#}9{#/blank#}(leave)in the fields add nutrients (营养物) to the soil after rice is harvested. For the next crop, rice farmers can often enjoy a good harvest by adding little {#blank#}10{#/blank#}no fertilizer (肥料).

A new high-speed railway opened on January 22nd, 2021. The new line which connects Beijing with China's north-eastern provinces not only shortens travel time. but also has high technologies, Besides, it also has an environmentally-friendly design. Importantly, it shows China's strong ability to build the high-tech and green high-speed railway, 

The new line connects Beijing with Shenyang, Changchun and Harbin- the capital cities of China's three north-eastern provinces.▲But now the newline shortens the travel time between Beijing and Harbin to less than 5 hours. People have never stopped realizing the goal of a higher speed. 

A part of the way from Harbin to Shenyang was put into work in 2012. The newline has 46 bridges and 30 tunnels（隧道）, " The building of the station is based on the idea of environmental protection, " the station's designer Wang Qingyi said. Also, an electricity-saving system has been used to save energy, Because of the new design lights will not need to be turned on during the day. Because the hall is bright enough for passengers. 

A new type of train that can work under temperatures as low as -40℃ runs on the line. The new train can stand the coldest weather and provide Braille (盲文). It has become attractive in the world. Many foreigners come to China to experience the new type train. Chinese people use their wisdom and hard work to tell the world that they are going to have a bright future.
