    The koala is unique (独特的) to Australia and is an important symbol of the country. The koala is found in open eucalypt (桉树) forests in south-east Queensland. Even if it is called koala bear, this animal has nothing to do with the actual bear. Koalas have thick fur and large cars.

    Their broad, flat nose makes them look cute, similar to teddy bears. In fact koalas aren't cute. They have sharp teeth and very sharp claws (爪)! Koalas are marsupials (有袋类). This means the mother carries her baby in a pocket while it develops, similar to a kangaroo. The baby koala lives in its mother's pocket for the first six months of its life.

    The name “koala” comes from a native Australian word that means “no drink”. The koalas get almost all their water from the eucalyptus leaves they eat. That's where they get their food too.

    Koalas eat only eucalyptus leaves. The eucalyptus trees are where the koalas live, it's also where they sleep. Koalas sleep about nineteen hours a day!

    Why do they sleep so much? Some people think it's because they're lazy. But koalas aren't lazy. They sleep so much because there isn't much nutrition (营养) in eucalyptus leaves. Koalas store hardly any fat, so they must save their energy. One way to do this is to move slowly and sleep a lot. After a day of sleeping they like to move around and eat just after sunset. They live alone most of the time. Koalas are very protective of their trees. If a koala sees another koala eating in its favorite tree, it might tell the other koala to leave by “barking” at it. Koalas do “talk” to each other.

    Besides barks, the males make a deep grunting (呼噜的) sound.

    The mothers and babies talk in soft clicking sounds. If they get scared they may scream like a baby. The koala is also an excellent swimmer.

    They are able to cross rivers to escape from heavy flooding (泛滥).

We've talked about snails (蜗牛) and their slow move. But much of the time snails don't move at all. They're in their shells —sleeping .

    Hot sun will dry out a snail's body. So at the least sign of hot sun, a snail draws its body into its shell and closes the opening with a thin cover. Then it goes to sleep. A snail will die in a heavy rain. So whenever it rains, it goes inside its shell house and goes to sleep. A snail can sleep for as long as it needs to. It can take a short sleep. Or it can sleep for days at a time. And it spends all the winter months in its shell, asleep.

    In spring the snail wakes up. Its body, about three inches long, comes out of from the shell. When hungry, the snail looks for food. It can't see very well. Its eyes, at the ends of the top feelers are very weak. But its sense of smell is very strong. It helps the snail to the new greens. Then the snail's little mouth goes to work.

    A snail's mouth is no longer than the point of a pin(针). Yet it has 256,000 teeth! The teeth are so small that you can't see them. But they do their work. If you put a snail in a hard paper box, it will eat its way out. And if a snail wears out its teeth, it will grow new ones.

    Mostly, a snail looks for food at night .But on cloudy days it eats in the daytime. It eats all day long. A snail can go on eating for hours and never feel full.

    Teenagers are known for being creative and full of new ideas. Let's have a look at these teenage inventions that might change the world.

Recently, a woman shared on the Internet that she had a birthday dinner not long ago. Before booking a table at a restaurant, she sent out a message to her friends and asked them to make an RSVP. On her birthday, the woman and her guests were very happy. However, a man who didn't make the RSVP arrived. Unluckily, there was no seat or meal for him. The man got angry and said the woman was a bad friend. She felt sad.

Many people commented on the story. Most of them said the woman did nothing wrong. The friend should have made an RSVP. So, what is an RSVP? Why is it important?

RSVP is short for the French word"répondez s'il vous plait", which means" please re- ply". RSVPing to an event like a birthday party is important. It can help the host know how many people will come to the event and so he or she can make a successful plan for it. The host needs to buy food and drinks, or sometimes spend money booking a nice place. It must take the host a lot of time and hard work to plan the event. So, making an RSVP can be very helpful.

If you get an invitation asking for an RSVP, please tell your host if you can go to the e- vent or not as soon as possible. It takes your host some time to invite you. You should also spend some time replying.

Tea and coffee are two of the most popular drinks in the world. However, people usually like one more than the other. These drinks also have very different uses. 

Tea drinking started in China over 4, 000 years ago. Tea is made from leaves. These days, some people drink tea for health, using it to help with stress or lose weight. However, most people in tea-drinking countries think of tea as more than just a healthy drink. In fact, tea drinking in some countries is a part of the culture. In Turkiye(土耳其), tea is always there when people meet. Whether in someone's home or a company, tea is always offered as a way of welcoming. In the UK, homes and offices usually have tea time. Tea and other dishes are served at tea time in the afternoon. It is a way to feel at ease with friends or co-workers(同事). 

Coffee came much later than tea, just over 1, 000 years ago. Coffee is made from beans. Something in the coffee beans makes a person feel active. Most people do not drink coffee to relax. Instead, they drink coffee to get going. Many people drink coffee in the morning to help themselves wake up. Others will also drink coffee during short breaks in the afternoon to keep going through the working day. Some people may visit coffee shops just to meet and talk with friends. However, many people in coffee shops drink coffee while working on their computers. 

Is tea or coffee more common in your country? Between the two, which do you like to drink more

A to-do list is like a note for you. Write down all the things you want to do or need to finish. It helps you plan your day and make sure you don't forget important things. What's on your list today? Maybe it will look like this.

For my brain         Doing homework, reading books 

For my body         Playing outside, eating delicious fruits and having a health y lunch 

Remember: put the most important things at the top, like homework before playtime.
