Hi, everybody. My name is Alice. I have worked as an airhostess(空 姐) for China Eastern Airlines for five years. I have some useful tips for you on taking flights.

    All passengers must arrive at the airport two hours before the departure time. You have much time to check everything. If you have never been to another country, don't forget to take your passports, air tickets and your suitcases with you.

    Have you got your boarding card(登机牌) yet? You must get it as soon as you arrive at the airport. Have you checked your suitcases and put name tags on them?

    If the suitcases are too heavy, you can find a trolley(推车). Have you exchanged(兑换) some US dollars? If not, there are a few banks at the airport.

    You can also have a meal at a restaurant before boarding. When you want to go upstairs, you can take the escalator.

    If you have any questions, you can come and ask me. We hope you will have a pleasant flight!

    Most cars run on gas. Gas cars work very well. But there is a problem. Cars that run on gas make the air dirty. The dirty air is not good for people, animals or trees. Gas cars make the air dirty for all living things. What can we do? We can drive electric cars!

    Electric cars do not use gas. These cars do not make the air dirty. These cars have batteries that power their motors (马达). The batteries can be charged (充电) many times. They can be used again and again. This makes electric cars great.

    But electric cars have problems too. They are slower than gas cars. They are also very quiet. This means that some people can't hear them when they go by. They may not think a car is coming. So they have to be careful.

    People are finding ways to make electric cars better all the time. Maybe one day all cars will be electric. That would be much better for the world.

They can easily find Planting Leaders and {#blank#}4{#/blank#}.

Shandong Province held the 36th Weifang International Kite Festival on the third Saturday of April in2019. A lot of kite fans from all over the world went there to join in the interesting festival on that day. Different kinds of beautiful kites flew in the sky.

Over 2, 000 years ago, a man named Gongshu Ban from Shandong Province invented a kite. It was made of bamboo. In the following centuries, kite-making developed well in China.

The first Weifang International Kite Festival was celebrated in 1984. In 1983, the Chairman of the Seattle Kite Association David Checkley took part in a kite show and later he visited several kite manufacturers(制造商). He found that kites made in Weifang were the best. He suggested holding the first Weifang International Kite Festival there. After that, Weifang began to hold it in April every year.

At the fifth festival, Weifang became known as the" Kite Capital of the World". Today, Weifang is home to over 300 kite factories. People in Weifang sell their products to about 40 countries and regions(地区) , making up 85 %of the domestic(国内的)markets and 65 %of the foreign markets.

However, there are also some problems. "Few people would like to learn about traditional kite-making," said Yang Hongwei. Yang's grandfather was once one of the best kite makers in Weifang. Nowadays, Yang still uses traditional ways and skills to make kites. In her opinion, only traditional things can last for a long time. Since the1990s, she has travelled to many countries to teach and take part in kite shows. "I won't stop teaching the ways of making kites as long as someone wants to learn. Meanwhile, the government should hold more kite festivals in China or even overseas, "she said.
