The kangaroo is the world's largest living marsupial (有袋动物). It was first found on the island of southwestern Australia. The animal was given its name by a famous English tourist in the 18th century.

    The kangaroo may be 7 feet(2.1m) tall when standing upright and the male can weigh as heavy as 200 pounds(90kg). The female (雌性) is smaller and lighter than the male. The kangaroo's head is small, but its ears are large, and its fore feet are really small. The animal has strong back legs and long tail.

    The kangaroo usually covers from 5 to 10 feet(1.5 to 3m) with each jump. The female is usually faster than the male. The mother kangaroo has a pouch (育儿袋) in its abdomen (腹部). The baby kangaroo grows up in the mother's pouch slowly.

    The kangaroo lives on grass and other plants. It is always moving from one place to another, lying down to sleep on the ground during the night. It likes to enjoy the warm sunshine. When it's in danger, it can use its back legs and strong tail to protect itself.

    Most of us think the telephone was invented by Alexander Graham Bell.{#blank#}1{#/blank#}In fact, an Italian named Antonio Meucci was officially recognised(认定)as the inventor a few years ago. Who is Meucci and why wasn't he known for his invention at the time?

    Antonio Meucci was born in Italy in 1808. He studied engineering and drawing. During his studies, Meucci started to experiment with electricity. {#blank#}2{#/blank#}When two places were connected with wire, people in those places could hear each other talk.

    In 1850, Meucci and his wife. Ester, moved to New York. Meucci was worried about his wife, because she had become very ill. {#blank#}3{#/blank#}To solve this problem, he connected metal cables between his home and his workshop. This way, they could talk to each other conveniently.

    Meucci invited a group of people to see his new invention. They listened in amazement as the voice of a singer was heard through the wires.

    {#blank#}4{#/blank#} Even worse, Meucci never applied for a patent (专利) on his invention. Meanwhile, Alexander Graham Bell was working on the same idea and in 1876 the patent for the telephone was given to him.

    In 2002, more than a century after Meucci's death, his work was finally recognised by the government. {#blank#}5{#/blank#}

    In a school, you may hear a student saying in Chinese,“我对汉语很感兴趣。“ but you're not in China. You're in a foreign country. Like the student, many foreigners are learning Chinese. But it's not easy. The Chinese use a different character(汉字) for each word. People have to memorize about 600 characters before they can do even basic reading and writing. For foreigners, it's hard to memorize them. And the following chart shows the top 3 difficulties for foreigners while learning Chinese.

    However, Chinese is more popular around the world today. The long history and colorful culture of China attract many foreigners to learn Chinese. With the rapid development, China is staying ahead in many fields and is playing its role in the world.

    Chinese is becoming a global (全球的) language and its popularity has risen around the world. Many countries set up Chinese courses in their schools.

    For example, in the UK, students used to choose between Spanish, Latin, French and other foreign languages. But now schools encourage their students to study Chinese. The increase in popularity of Chinese has been surprising. 1031 people took Chinese language exams in 2001, and the number was 2062 last year, while 2561 people chose Spanish. It's predicted that studying Chinese in the UK could overtake (超过) Spanish in less than five years.

    Just like the foreigners do, we also learn foreign languages. Different languages carry different cultures. So exchanges are necessary. By learning a foreign language, we not only have a useful tool of communicating, but experience a new culture, what's more important, learning a foreign language well will help us tell our own stories to the world.

    Rice, meat, vegetables and fruit… there are many different food choices for us to eat every day. You may think that throwing away your leftover food is not a big deal. But you should keep in mind that many people around the world still don't have enough to eat.

    In 2015, there were over 1 billion hungry people in the world, according to the United Nations. Many children went to sleep hungry and 15 million of them even died from hunger.

    However, food waste is still a big problem. The average person throws away 50 kg of food every year. This means that 1.3 billion tons of food goes to waste each year. That is more than one third of all the food we make.

    We could give this leftover food to many people. For example, the amount of food wasted in Europe would be enough for 200 million people!

    So next time you feel picky (挑剔) about what you want to eat or can't finish your meal, you might want to think twice. There are many others who aren't so lucky.
