    With the development of modem technology, there are plenty ways for us to contact people. One of our most favorite ways is probably WeChat. The main reason may be because it is very convenient to use with the popularity of the smart phone. We can contact friends whenever it is but wherever we are. We like using WeChat also because it is very cheap. It costs only a little and is even free unless Wi-Fi is available. Another advantage lies in the speed with which messages get sent and received. It's so fast that we can get in touch with others instantly. More importantly, using WeChat, we can give friends not only very exact written informations but also very moving greeting words, that we might not say face to face. Besides, music as well as pictures and videos are often uploaded through WeChat, so it is now a useful entertainment tool.

In a word, using WeChat is a good choice for you to keep in contact with friends.

    As we all know, questioning can lead to searching for an answer. If we are in the habit raising doubts as to whether that we are told is true, we can find the correct answer and learn more.

    Two years ago, our teacher offered us an answer to a difficult math problem in class. Although the answer seemed a little strange, but nobody except me doubted it. Think that his answer might be wrong, I carefully analyzed the problem and tried to work them out in a different way. Half a hour later, I managed to find the correct answer. When I showed my answer to him, the teacher praised me as my independently thinking.

Dear Mr. Black,

    I'm very thank to you for inviting me to stay with you in the come summer vacation. I have been dreamed of seeing you again so that I can get help from you in my English learning. And I'm afraid I cannot go to your place in this summer. I've promised my grandmother, she lives in the country, to spend this summer with her. She misses me too much that I find difficult to refuse her request. I'm busy preparing for my examinations in present. I planned to visit you in winter if it's convenient to you.
