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!

    Electricity is an important part in our life. We can't see or touch it, but it is all around us. Our life will be terrible without electricity. But some people don't know that everyone should save electricity. When it is not completely dark, many street lamps (路灯) light up early in some streets. Some people don't turn off the lights when they leave the room. Some people are sleeping with the lights on. They are all wrong. Here I make somesuggestions about stopping these things:

    *Turn on the street lamps on time. We light them from 7：00 p. m.～5：30 a. m. in summer, and from 5：30 p. m.~6：00 a. m. in winter.

    *If some small areas are very dark, just turn on a few lights.

    *The distance (距离) between street lights can be 50～60 meters. It can save electricity and money.

    *If there are some activities, such as fairs, we can make the lights bright；if there is no activity, lights needn't be too bright.

    Ask people to save electricity through TV shows, newspapers, and so on.

    Electricity is a valuable resource (资源). It helps us live well and conveniently. We should take action to save it at once!

A study conducted by the University of Leeds in the United Kingdom suggest that watching cute animals may lead to a reduction in stress and anxiety.

The study examined how watching images and videos of cute animals for 30 minutes affects blood pressure, heart rate(心率) and anxiety. In December 2019, 19 people, including 15 students, joined in the study.

"There were some kittens, there was puppies, there were baby gorillas, there were quokkas —cute creatures found in Western Australia, are often referred to as 'the world's most cheerful animals'." Dr. Andrea Utley, a professor at the University of Leeds told CNN. The study was timed during winter exams, a time when stress is at an especially high level for students, according to Utley.

 The study recorded that the average blood pressure dropped from 136/88 to 115/71, which the study pointed out is "within ideal blood pressure range." Average(平均的) heart rates were lowered to 67.4 bpm, a reduction of 6.5%. Anxiety rates also went down by 35%.

"I was quite pleasantly surprised that during the session, every single measure for every single participant dropped some — heart rate reduced, blood pressure reduced," Utley said. "When they left, they filled the questionnaire(调查问卷) in again and showed that they were feeling less worried."

When questioning the participants, the study found that most preferred video clips over still images, particularly of animals interacting with humans.

 What does taking the train mean to you? Perhaps it's just a way of getting to {#blank#}1{#/blank#}( you) destination(目的地). In fact, the train itself can be part of the fun.

 On March 28, China's {#blank#}2{#/blank#}(one) panda- themed tourist train left Chengdu in Sichuan for Zunyi in Guizhou. It soon became the talk of China with its special design (设计) and {#blank#}3{#/blank#}( comfort) service. It's one of {#blank#}4{#/blank#} most interesting trains in China.

 Its inside and outside are decorated with giant panda {#blank#}5{#/blank#}(picture). Attendants(乘务员) carry panda toys and passengers can try panda- shaped food, as well as Sichuan snacks.{#blank#}6{#/blank#} there are many kinds of rooms to have fun, some people call it a" mobile star hotel". Passengers can take showers and use its 5G network as well. This excellent service is one thing that has {#blank#}7{#/blank#}(excite) travelers. And train travel fascinates people for other reasons.

 In the fast- paced times we live in, train travel is a good way {#blank#}8{#/blank#}(slow) down. It gives you time and space to read, sleep, chat with friends, or {#blank#}9{#/blank#}(simple) do nothing but watch the changing views outside. Train travel is also full {#blank#}10{#/blank#} surprises. You might meet new people and become friends with them.

Young people often feel unhappy when they are with their parents. They say that their parents don't{#blank#}1{#/blank#} them. They often think their parents are strict with them.

Parents often find {#blank#}2{#/blank#} difficult to win their children's trust and they seem to forget how they felt when they were young.{#blank#}3{#/blank#} example, young people like to do things without much thinking. Older people are worried about things more easily, they need to {#blank#}4{#/blank#} things from many ways. So most of them plan things {#blank#}5{#/blank#} and don't like their plans to be changed.

Young people often make their parents angry by clothes they want to {#blank#}6{#/blank#}, the music they enjoy and something else, they don't really want to make trouble. They feel that in this{#blank#}7{#/blank#} they can be away from the old people's world. They want to make a new culture of their own. But if their parents don't like their {#blank#}8{#/blank#} or clothes, the young people will feel very unhappy.

Sometimes instead of going out with their parents, they {#blank#}9{#/blank#} want to stay at home alone and do what they like.

{#blank#}10{#/blank#} you plan to manage an independent life, you'd better win your parents' trust and try to get them to understand you. If your parents see that you have a high sense of responsibility (责任感) , they will certainly give you chances to do what you want to do.

In ancient(古代的) China, people(人) have three names: the {#blank#}1{#/blank#} name, given name, and courtesy name(字).

 Look at Li Bai, his family name is Li, his given name is Bai and {#blank#}2{#/blank#} courtesy name is Taibai. Some people call him Li Bai, {#blank#}3{#/blank#} some people call him Li Taibai.

 When do people use their given {#blank#}4{#/blank#} and courtesy names? When(当……的时候) people are at home, they usually use their given names. But when they are {#blank#}5{#/blank#} at home, people use their courtesy names.
