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!

    One day, Jack's parents told him that his grandpa would retire (退休) after working for forty years. Jack said1, "I'm only seven, so it means my grandpa has been…er…a really long time!"

    His parents said, "Yes. There is a (n)2place in his heart that we don't know how to fill. That's why we are going to have a surprise party for him."

    Jack loved his grandpa and wanted to do something3for him. He remembered the business card his grandpa had given him two years before. He knew that his grandpa would no longer hold the position on that card, so he decided to build a new one for his grandpa.

    When the big night came, Jack was4. He put his gift in a small box. But he didn't want to put his gift together with others'. He carried it around with him the whole5.

    When all the other people6, he took his grandpa's hand and brought him over to a chair and gave him the gift.

    His grandpa smiled, "Well, it must be a beautiful7. May I open it now?" "Sure!" Jack said excitedly.

    As Jack's grandpa opened the gift, tears came into his eyes. He was touched by Jack's gift. Jack gave him the greatest gift he had8got! It was a business card with his new position FULL-TIME GRANDPA! Jack said, "Now your9job is my grandpa."

    "Well10do l get paid?" his grandpa asked, smiling. "As many hugs (拥抱) as you want!" With these words, Jack gave his grandpa a hug. "Well, I guess that means I'm the richest man in the world!" said the grandpa.

    Hello, boys and girls. I'm Tom. Nice to meet you. Tom is my first name, What's my last name? My last name is Hanks. Tom Hanks is my full name(全名). I'm twelve years old. I'm from England and I'm English. Thanks.

    Nowadays we can see more and more electric bikes in the street. Electric bikes 61. {#blank#}1{#/blank#} (be) easy to ride. They run fast and make no {#blank#}2{#/blank#} (pollute). They become very popular, {#blank#}3{#/blank#}the electric bikes also cause more traffic accidents. So China plans {#blank#}4{#/blank#} (make) a new rule for the electric bike riders. If an electric bike is {#blank#}5{#/blank#} (heavy) than 40 kilos and can go faster than 20 kilometers an hour, its rider must get a license. It means some riders have to pass driving tests before they ride {#blank#}6{#/blank#} (them) electric bikes on the road.

    People have different ideas after {#blank#}7{#/blank#} (hear) the plan. Some welcome the plan. A bus driver said happily, " {#blank#}8{#/blank#}a good plan! I think it will make the street much safer." Some are not happy with the new rules at all. One rider said {#blank#}9{#/blank#} (sad), "I don't want to get a license. It's not convenient {#blank#}10{#/blank#}me to get one." Some don't care about it. A young rider said calmly, "I prefer to use shared bikes which are popular in many big cities of China now. I hope they can come to Loudi earlier!"

I am a Grade 9 student. I have {#blank#}1{#/blank#} problem, and I do not know how to deal {#blank#}2{#/blank#} it. I have a lot of homework every day, and I have no choice {#blank#}3{#/blank#} to do it. I often stay up late to complete my {#blank#}4{#/blank#}, and then feel tired the next day. Sometimes I want to {#blank#}5{#/blank#} to do so much work, but usually I just accept it. I understand that {#blank#}6{#/blank#} is important to do my homework on time. However, I hardly have any {#blank#}7{#/blank#} time for my hobbies, such as playing volleyball and ping-pong. I really feel bad about that. I often doubt whether it is worth {#blank#}8{#/blank#} so hard.

I am {#blank#}9{#/blank#} forward to a holiday without homework so that I can relax and have some time for my hobbies. What should I do? Can you offer ni e some {#blank#}10{#/blank#}?

Astronauts would face dangers both getting to and surviving (生存) on Mars. Let's learn about surviving a trip to Mars.

What would it take to keep people safe and healthy on a trip to Mars? Scientists are already working on it, though the trip may be many years later.

Over the last 60 years, many spaceships have flown by orbited（沿轨道运行）and even landed on the Red Planet. However, machines cannot replace humans. That's why the United States, China and other countries want to send people to Mars. But surviving on this trip would not be easy.

A trip to Mars would be the farthest journey in human(人类) history. Mars is about 225 million kilometers away, so it would take astronauts at least 180 days to reach there. However, it only takes a few days to get to the Moon.

Space travel is dangerous. For one thing, staying in space for long periods makes the human body weak. Also, it puts pressure behind the eyes and causes eye problems. But gravity(重力) machines could help.

Then there's space radiation(辐射) to worry about. It is bad for astronauts when they have long journeys. Scientists are working out the issue. They have found that taking certain vitamins can help.

Astronauts will have to pack light to lift off from the earth. But they won't be able to get the things they need easily. Astronauts on the space station practice for this by growing lettuce and other food in space. Engineers are developing 3D printing techniques（技术）which can allow future Mars astronauts to build what they want.
