In 1901, Karl Landsteiner, an Austrian scientist, discovered that there are four types of blood. These four blood types were named A, B, AB and O. People have one of these four types. Blood type O is the most common around the world. Blood type A is the second most common, and type AB is the least common. If people with type A blood are given type B blood, or people with type B blood are given type A blood, they will probably die.

    In 1927, a Japanese doctor, Furukawa Takeji, carried out research and came up with the idea that people with different blood types also had different personalities(性格). He said that people with type A blood are usually calm and serious; people with type B blood are curious, cheerful and outgoing; people with type O blood are generous and trustworthy; while those with type AB blood are often caring, original and careful.

    More recently, a doctor in the United States wrote a book that links blood types and what people eat. For example, his book suggests people with type O blood should eat more meat and less bread. A diet for people with type A blood includes more vegetables. His book, Eat Right for Your Type, has been a hit with people who want to lose weight. However, Dr. Peter D' Adamo believes that eating food that matches a person's blood type can help them lose weight. He thinks it will make the person healthier in other ways, too.

Our movement spend a lot of time and money improving the city's traffic. They build more roads and make stricter rules. However, do they really work on the {#blank#}1{#/blank#} problem!

Clearly, they work little because the speed (速度) of building more roads is slower than that of cars' growth. 

Why not{#blank#}2{#/blank#}down, the growth of cars and speed up the roads' building? This way is much better than that of just {#blank#}3{#/blank#}more roads. Although there are stricter rules to let cars run on the road in{#blank#}4{#/blank#}tones; traffic still grows heavier and heavier. The {#blank#}5{#/blank#}one is the traffic restriction (车辆限行). This rule improves the city's traffic in someway {#blank#}6{#/blank#}snot too much, for example, Jack's family live far away from the city {#blank#}7{#/blank#}a my parents have to drive to work but they can' t drive their car on Tuesdays. What will they do to solve (解决) the problem? The fastest and best way is to buy {#blank#}8{#/blank#}car and ask for a different license plate (汽车牌照), In this way, they can go to work {#blank#}9{#/blank#}like before. 

I hope our movement can develop a better plan {#blank#}10{#/blank#}be the situation. Fewer cars mean fewer traffic problems. 

About 38,500 kinds of animals in the world are in danger. Now, you can learn about them and help them by playing a card game.

 Jackson Mann is 15 years old. He is the starter of the card game called"SOS: Save Our Species(物种)". He hopes that people can do something for endangered(濒危的) species after playing the game.

 In the game, players need to collect endangered species and match them with their right habitats(栖息地). The more endangered the species are, the more points players can get. The game finishes when there are no more cards. And the player with the most points wins the game.

 Jackson had the idea for the game on a family trip to Central America three years ago. "We saw lots of wildlife and played lots of card games," said Jackson. "I thought that it would be great if people could play cards and learn about endangered species at the same time."

 Jackson's card games began to sell from July 8,2022. So far, he has made over£11,700 to help save animals in danger.
