Dear classmates，
Nowadays many of us use social networking apps as different purposes.In opinion，using social networking apps too much bring some negative effects. First，if we spend too much time on social networking，when should have been used in studying and taking part in outdoor activities，our study and health will gradual be affected.Second，by chatting the online，we may not know how to communicate with people face to face，which was bad for our relationship in the long term.Worse still，there is some unhealthy informations on social networking sites.
Besides，let’s turn back to our lessons instead of focused on the social networking apps.
Thank you for listening.
According to a survey, the number of road accidents has increased over the past year. This notice is aimed on increasing people's knowledge of the problem. Below is some of the major causes of road accidents and that drivers should do to prevent them.
Some drivers are aggressive, that is not safe because it can result in crashes. What is more, although the person who has been drinking is your friend, but do not allow him to drive. Lastly, speed kills. Driving too fast through city streets is very dangerously. So far, a lot of people have killed due to traffic accidents.
In the word, how I wish there will be no traffic accident in the future. The world building by us is full of safety and love.

It is reported, some needy students receive financial support of some kind people but never express our thanks. Personally, I think they are wrong.
Though the helpers didn’t expect any reward in return, but it’s necessary and good manner to say “thank you”. Besides, it is a basic social skill express ourselves in modern society. Maybe some of them do feel thankfully. It is only because they are afraid of being looked down upon which they remain silent. But I just want to say that being poor for a moment doesn't mean you will be poor forever.
