Everyone that lives in big cities such as Beijing, Shanghai, Guangzhou etc, knows that there is a lot of traffic! Wherever you go, you can see the crowded streets with cars, buses, bikes and people. It seems that everyone is always in a hurry! In such a situation, accidents might happen. But if we all slowed down a little and paid more attention to the traffic rules, accidents would be avoided(避免). However, sometimes the fact isn’t like that!
How many times have you tried to cross the street even when the light has become red? It seems as if it would be so easy to just quickly run across, or rush in between cars and buses. But this causes a dangerous problem. Crossing the street when the light is red will only save you a few seconds; it is not worth(值得的) risking(使……冒险)your life.
When I was growing up, my mother always told me the two sayings “Better safe than sorry” and “Better late than never”. That’s to say, it is always better to be careful and arrive safely at the place you hope to go. Things would not be much worse if everyone would wait their turn to cross the street.

For Wilson, the two most important things to take with him when he travels abroad are his passport and his mobile phones. He books his plane tickets and hotel rooms through the Internet, and he enters all the information into his mobile phone. “I don’t even need to print my tickets out any more,” says Wilson. “I can do everything online.”
How people travel and go on holiday has changed a lot over the past years. Airlines, hotels, travel agencies all have their own websites. People can plan and book their holidays in just a few clicks. Today everything is easier, faster and smarter.
In fact, many people do not use guidebook any more. Instead, they go to travel websites for the maps and information. These websites also let travellers write about and show photos of the sights, hotels, shops and restaurants they went to. This means other people can read about their experiences and decide whether they want to visit these places too.

My favourite place at school is the reading room. I like reading newspapers and books there because they not only provide me with much knowledge, but also help me learn a lot about what is happening around the world. Sometimes, I even feel I can have a talk with the people in the books. I can also relax myself in the quiet environment there. When I feel tired or happy, the reading room is the best place to go to.

Dear Sir
I hope you can help me with my problem. I have lived in Hill Town all my life. In the past, many tourists came to our town to boat on the river and look at the beautiful views. However, no one comes to boat on the river any more. Three years ago a factory opened here. It dumps all its waste in the river. The water used to be clear and blue. Every summer local children would swim in it. Now it is brown and dirty. It is impossible to see the bottom of the river. Local people used to catch fish here. Now all the fish are dead. Please do something to stop the factory polluting our town. Yours

In recent years, WeChat is becoming fashionable and popular. It has made a difference to our daily life.
We used to get in touch (communicate) with each other by letters and emails, but now more and more people are using WeChat. We can send voice and text messages through WeChat as well as pictures and videos easily. By using it, making friends is becoming easier. And we can share our life experiences faster. However, there are also some problems. Using WeChat too often is not good for students’ study. And it is not safe for students to make friends by WeChat.
I think WeChat is helpful to us, but we should always be careful.
