Josh is a kind boy. Last month, he went back home by 1. Before he left the train, he found an iPhone 4. 2 lost it there. He decided to 3 it to the train office. Then the phone rang (响) and he answered, "Hello." A 4said, "Hi, this is Michelle. You're using my phone. I 5it on the train." Josh said, "Yes, I found it. And I will take it to the train office." "Oh, that's very nice of you. If you leave your address (地址), I would like to post you ￡20 to 6 you." Josh said no problem. When the woman came, she got her 7 and a piece of paper (一张纸). Josh left it for 8. She thought it was his address,9it wasn't. On the paper she found "Don't worry about the 10. Just do something nice for others."

    Recently I have read another great book by Mark Twain.1name is The Adventures of Huckleberry Finn.

    Huck Finn and Tom Sawyer are best friends. They have had so many adventures.2this book tells about Huck and another friend of his, Jim.

    Huck lives with a rich3after he finds a box of gold with Tom Sawyer in a cave.4Huck's real dad comes and takes him away from the family. Huck's life in his dad's cabin(小木屋) is5so he cuts a hole in the cabin. Then he manages to make people6that someone has killed him.

    Huck runs away to a small7. Jim is on that island. He is very sad because he thinks that his owner wants to8him.

    Then they go on adventures together. They9die in the wheels of a huge paddle boat and they live on a raft(木筏) with two frauds(骗子).

    Well, that's 10I want to tell you here. It's really a good book. It has lots of adventures and Tom Sawyer will show up.

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.

Amy lives far from her office. Five days a week, she gets up at about 5:30in the morning. After a quick breakfast, she walks to Finsbury Park Station.From there she goes to King's Cross Station in London by train. Then she goes to Holton in a bus. After that, she takes a taxi to her office. She gets there at about 8:00. It usually takes about two hours from her home to her office.

When I was 5 or 6 years old, I was a naughty (调皮) boy. One day, I tried to steal gum from the drugstore when my1 took me shopping. I stood in front of the gum shelf, waiting for the right moment. After about302 , I finally made my move, just as my mum was calling me to3 . As we walked away, a store worker walked up to my mum and told her that I had taken a pack of gum.

My mum was really angry and insisted that it was4 for me to do so. She thought her son was honest, good, and 5 lied or did anything bad. However, the store worker explained that all the workers, from the very beginning, had been watching me for half an hour. It was challenging for them to wait so long before I 6 did it. To prove they were wrong, my mum searched me, checked my pockets, and found7 . The man was surprised, and my mum was proud and even scolded (责备) him.

Seeing the man's face turn red, I felt very sorry. I had to make a choice. As he started to walk away, I 8 my cap, reached inside, and offered the pack of gum to him. I said 9 with all my heart. Both the man and my mother were shocked, for different reasons.

Though I was punished, I felt less guilty because I10 becoming a worse person. Better late than never.
