Doing Things at The Same Time Is Acceptable
(1)Many people argue that it is doing so many things at the same time that leads people fail in doing things well．(2)However，from my point of view，the real reason is that people ale easily tempted to distract their attention from social networks and then forget to do what we need to do first．
(3)To begin with，people nowadays unconsciously devote too much time to social activities，which make peopie fail to concentrate on what should be done．(4)For
instance，a college student may want to study hard in the class and do homework as carefully as possible．However,some meaningless activities like parties and chatting
on QQ or Wechat waste so much time．It is not difficult to imagine how well the work would be done in such ab．sent．minded state．
(5)In addition,many people can not realize which Things should be placed on the priority and which are trivial．
(6)Provided that people have a better clue of what they should put more efforts into and do each thing in accordance with importance indicator，they can do things systematically well at a time．
(1)文章首句用强调句型引入人们的观点。
(2)用however一词指出自己的不同见解。From my point of view意为“在我看来”。
(3)第二段以To begin with开头，给出支撑自己观点的第一个解释。
(4)此处是对第一个原因的举例。For instance意为“例如”。
(5)本段以In addition“另外，此外”开头，给出支撑自己观点的第二个解释。
(6)本段给出解决问题的办法。Provided that意为“如果，只要”。
(7) In sum, doing things at a time is not the main reason. People should first reflect whether they pay full attention or not to those things that must be done.
(7)结尾进行总结，强调同时做很多事并不是主要原因，人们首先应该反省是否能专注于必须要做的事。In sum意为“总而言之”。
