Microblog has_become_part_of_our_life.It is very convenient for people to express their feeling instantly at any time.Besides,it provides a chance for people to release their inner stress.By showing their heartfelt emotions on the microblog,their friends may also know about their condition and can offer timely response.However,microblog can also be potentially dangerous as it may give away people’s privacy and other significant information.In my opinion,microblog provides us with some concerns as well as emotional comfort and large quantities of information,so we should be careful while using it.
