    With the development of Internet, relative services are developed in the form of websites or apps on phones too. Here introduces you Airbnb and Uber.

    1 Airbnb (air Bed and Breakfast)

People can offer or rent rooms for a short time on Airbnb website or its app on smart phones. The cost is usually cheaper than that of hotels. Travelers can book rooms with special activities such as enjoying local music, art and food.

    Airbnb was founded in August 2008, and now it has over two million listings for travelers to choose in the world. The idea of Airbnb, as its symbol shows, is about home and trust.

    2 Uber

    Uber is a ride sharing and taxi app for fast rides in minutes—day or night. It was founded as Uber Cab in March 2009. The Uber app can send an order to the nearest Uber driver, asking him to the location soon. Users can track the car on their smart phones, so they can know when it will arrive.

In August 2016, Uber service was provided in 507 cities and over 66 countries. However, in China, its operation was acquired by Didi in July 2016. The website Bloomberg View said in July 2015 that Uber makes it easier for people to get a taxi.

      What's going to happen in the future? Will robots control our planet? Will computers become smarter than us? Not likely. But here are some things that scientists say are most likely to happen in 10 to 0 years from now, according to the BBC.

 Digital money      

      We used to pay with cash(现金) for everything we bought. Now when we use a credit card(信用卡) to shop online, money is spent without us seeing it. That means we are already using digital(电子的) money. Using a card is much easier than searching our pockets for change. It is also safer than carrying a lot of cash.    

When ATM cards were first introduced, they were not accepted everywhere. But now it's hard to live without them. It's reported that people in Sweden completely stopped using cash last year, and the US might be next.

Bionic(仿生的) eye    

It's no longer something only in a science fiction movie. People who are blind may have a chance to get their sight back—by wearing bionic eyes.

      A blind eye can no longer sense light, but a bionic eye can use a camera to “see” the environment and send data(数据) to the mind. Now the bionic eye only allows patients to see lights and unclear shapes. A high resolution(高清的) image could be just a few years away. 

Self-driving cars     

      Unlike a human driver, a self-driving car won't get distracted(分神) by a phone call, the radio or something outside the window. Sensors (探测器) and cameras on the car would allow it to stick strictly (严格地遵守)to the rules of the road and keep a safe distance from other cars. This would greatly reduce（减少） the number of road accidents. You could even take a nap while the car drives itself. In the future, driverless cars would be widely accepted.

    How much do you know about the bird world?

    Birds use three gaits: walking, running and hopping．

    In walking, the left and the right feet move in turn (轮流)．Each foot is on the ground for more than half the time, so there are more times when both feet are on the ground．In running, each foot is on the ground for less than half the time, and there are more times when both feet are off the ground．In hopping, the feet move almost at the same time．This means that for much of the time both feet are off the ground．

    Middle-sized and large birds walk at low speed and either run or hop at higher speed．Small birds, such as sparrows and swallows, usually do not walk, because walking may be too slow for them．It seems that the more time a bird spends in trees, the more likely it is to hop．Perhaps there is wide space in a tree between one thin branch (树枝) and the next, so walking is not a good choice, while on each small branch there is enough room to set both feet down side by side, so hopping seems to make sense．

There are many ways to manage (管理) time. A clock plays an important role in time management. It can help us make our goals (目标) come true. We can use it in many parts of our life and it helps us say no to wasting time. The following ways can help us get started.

Learn about the meaning of 30 seconds. For example, if your house is very dirty, think about this. Failing to (未能做) hang up a coat and keep a desk or room tidy happens when we leave out (忽略) the quick housework. We can play a game to see if we can build a clean and comfortable environment in 30 seconds.

If possible, exercise at a certain time. For example, exercise at 7:00 a.m. and have breakfast at 8:00 a.m. every day. Also, we can ride a bike, run slowly or go for a quick 15-minute walk twice a day. The 15 minutes seems like a short time, but if we keep at it, it can make a difference to our health.

Go to bed and wake up on time. This is the most important way and it makes us full of energy (能量). It also makes us healthy and benefits our study and work.

Pairing every goal in life with a clock makes it easier to come true. We should learn to manage time and make full use of every minute.

Collecting scrapbooking (剪贴簿) is a kind of hobby. It is popular for more than 500 years. Some people call it a friendship book. They keep pictures, letters, poems and other things they want. Today people collect many things in scrapbooks. Some people have funny collections, like pictures of the world's most ugly dogs. Other people may collect stories about the bad weather. 

To start your scrapbooking, first, you should decide what to collect. Start with just one idea. Next, you need a book with paper, scissors and glue. Then use the scissors to cut out the pictures or stories. At last use the glue to stick them to the background paper. 

Scrapbooking is so popular these days. I think people want to record their family history and show it to other people. When I was a boy, I always saved bits of paper, things like movie tickets and holiday postcards. I made my first scrapbook for my grandfather ten years ago when he died. When I sat at his desk, I found some wonderful things like my grandfather's birthday cards and photos in the past, then I put them in the scrapbook. After that, I made two more scrapbooks for my brother and me with beautiful collections. I want to keep those happy and beautiful memories (记忆). That's the real meaning of scrapbooking. 

China is a country with many colourful days and festivals. The Dragon Head- Raising Day is one of them. This special day is on the second day of the second month in the Chinese lunar calendar. {#blank#}1{#/blank#} The dragon is important in Chinese culture. We Chinese people call ourselves " the descendants(后代) of the dragon". {#blank#}2{#/blank#} On the day in ancient times, people put ashes in the kitchen. This was to" lead the dragon into the house". People believed that with the help of the dragon, they could have a good harvest(收成) in autumn. 

Also, people eat special food on that day. {#blank#}3{#/blank#} For example, people eat "dragon's beard" noodles and dumplings called "dragon's ears". 

Today, many customs have disappeared. {#blank#}4{#/blank#} It was said that a haircut during the first lunar month may bring bad luck to the uncles of a family — mother's brothers. So many people have their hair cut on the Dragon Head-Raising Day.
