Composition exercise Nowadays,as the technology goes further,there are many ways for people to get a abundance of information.However,can you guarantee the information you get is useful for you?I think there are two main reasons why people have a difficulty in acquiring useful information.First of all,due to Big Data technology,all parts are connnected online,for example,you look through some merchandises on the shopping app,and other apps maybe present you the advertising of these merchandises.So the connection produces a lot of useless information online.Followed by the ability of sifting through information is not enough.people can not sift through the useful information from the information in abundance.All in all,in my opinion,​we have to increase our ability of distinguishing the useful information.And we don't have to get the useful information from online,instead books are better.

China's urbanization In the course of china's urbanization,2011 is a significant moment,and city populations are more than rural populations firstly.In the following 20 years,it is estimated that around 0.35 billion rural populations are going to migrate into city.Such a massive development is not only a challenge but also a chance to city transportation.Chinese government always insists that people should take buses to go outside instead of driving private cars.It also call on establishing resources-conserving and environment-friendly society.Under this exact aim,china's cities can project its development and pour an aboundance of capital into secure, cleaning and economical transportation system

The impact of social networking websites on reading Reading is the key of broadening our horizon,so it is necessary for us to read books.However,someone just likes reading on social networking websites,such as weibo, the chinese version of facebook.They even look through these websites all day. as we all know,traditional paper books are fundamentally different from social networking wesites.I think social networking wesites have three main impacts on reading.To begin with,there are a substancial number of information online,including some beneficial or fake information.If readers can not distinguish these information,they may be misleaded .Followed by something funny on social networking websites may distract you from the paper you are reading.Instead,as saying goes,“every coin has two sides”.Reading on social network websites is able to present us the newest information in our daily life. All in all,no matter where we read,reading is beneficial to us.As long as we have the ability to distinguish fake news and highly concentrate on reading,reading is working for us.

Essay commenting on Alert Einstein's remark According to Alert Eindten's remark"i have no special talents.I am only passionately curious".In my opinon,I think both two are very crucial to the greatest achivements he have ever made.If one person's IQ is much lower than any other people,being strongly curious is far from enough.so i can say they are no more than modest words. Having special talents is a ladder to success.In terms of my own experiences,a lot of my friends having special talents,such as maths gift or music cells,have a better life than their peers. Furthermore,everyone are able to be curious about something they are interested in.so i think special talents are the most important ,and having curiosity is less important. I believe all greatest people like him are both talented and inquisitive.beacuse talent is the base which decides whether one person have the ability to make a reseach.Curiosity is just a motive power that pushs you ahead.
