    With the development of modern technology, there are a plenty of ways for us to contact people. WeChat is probably our favorite, mainly because of its convenient. We can keep in contact with friends whenever it is and wherever we are as long as Wi-Fi is available. Another advantage is it is a relative cheap and quick way of communication. As messages get send and received instantly, the cost of making phone calls is cut down. Besides, music as well as pictures and videos are often downloaded through WeChat, but it is now a useful entertainment tool. However, problems exist at the meanwhile. For example, your identity can be easily revealed, so we should pay attention to protect our personal information.

    It's reported that some Chinese tourists behave badly travel at home and abroad. They speak loudly in public places, carve characters at tourist attractions, throw a rubbish everywhere, even cross the road when the traffic lights are still red. Such bad behavior had caused damage to what people think of themselves and our country. Actions should be taken to stop this. First, tourists should be educating to obey social and public order, and respect locally religions and customs. Besides, laws should be made to punish those which don't behave politely in public. I hope soon tourists will change their behavior and win respect of themselves and our country.

Dear Editor,

    I'm writing to tell you about a food poisoning accident. Several days ago, my neighbor ate a bag of food buying from the market. After the meal, they had stomachaches and their faces turn pale. Lucky, one of their friends found the accident and immediately called an ambulance, which carried them quickly to a hospital. After several hours' treatment they finally escaped of death.

    As some businessmen are only interested in making money to become rich quickly, we seldom care about the necessary safety measures or which happens to buyers. They must be have charged by law. Meanwhile, I do hope whole society can realize the important of food safety.

    I have two pets, Polly and Sally. They are green-and-blue parrot. Their home is a shady tree in the garden where they are freely to fly from branch to branch. There has a wooden box for them in a tree. This is their nest, where they sleep at night there and take shelter whenever it rain. Every morning, after clean their nest, I feed them with some seeds and give them a bowl water to drink. They are pretty and lively birds. This is really interesting watching their movements, because I never feel dull spending my time with them.

    Many students tend to copy others' homework while the deadline comes, as is often the case. But nowadays, more students chose to hire someone to write to homework for them. Therefore, on-line ghostwriting has emerged to meet students' needs. In our surprise, parents make up a large part in those homework buyer.

    Too much homework may be main reason for ghostwriting phenomenon. Many students cannot finish their homework on time, but they do this to avoid the punishment of their teachers. Beside, poor sense of time makes this too late for students to finish homework before deadline.

    In my opinion, proper amount of homework and the cultivation of sense of time may help solving this problem.
