(2018·合肥市高三调研性检测)

Social networks are a big part of nearly every teenager’s life in this day and age. Many teens have QQ, WeChat, or Weibo but little do a lot of teens know that they can be held responsible for everything they post for the rest of their lives. Everything you post online is part of a digital footprint that can always be traced(追踪) back to you. That includes every post, even every like，comment, favorite and forward that you have ever committed. All pictures you’ve posted or will post have been stored in a digital database, and it is the companies’ right to keep all of these documents that you believe to have been deleted or hidden.

With every post comes a consequence; whether it is good or bad，what you post could be seen by anyone. That is why you have to be very careful of what you decide to post or comment.

If you think you are safe from Servite finding out about one funny comment you made six months ago on a meaningless picture, you are probably wrong. Recently, a senior, Aaron, at Servite learned this lesson the hard way this year. He wrote a series of ugly comments towards Connelly girls on a web page, ignoring potential consequences.

This student, however, did have to face consequences from Servite as he was removed from all of his leadership roles in the school. Surprisingly enough, he fully agreed with his punishment handed down by the administration and fully understood why he was given such severe discipline(处罚). “When you agree to come to Servite, you are agreeing to defend what Servite stands for，” the young man said. “That continues from 8 a．m.to 2 p．m. It’s at all times.”

So, next time you’re about to post something you think could be received as offensive or inappropriate, think twice, or don’t press the “Send”．【解题导语】本文是一篇议论文。当下很多青少年拥有微信、QQ、微博等网络社交工具，但是他们很多人都不知道要对自己所发布的内容负责。文章通过一名高中生的事例说明，在网上发布信息应当慎重。

(2018·兰州高考实战模拟)In many developed countries, people who have high degrees begin to work lon ger than those who don’t. About 65% of American men aged 62－74 with a professional degree are in the workforce(劳动人口), compared with 32% of men who only finish high school. This gap is part of a deepening divide between the well­educated wealthy and the unskilled poor. Rapid technological advance has raised the incomes of the highly skilled while squeezing those of the unskilled. The consequences, for individuals and society, are profound.

The world is facing an astonishing rise in the number of old people, and they will live longer than ever before. Over the next 20 years the global population of those aged 65 or more will almost double, from 600 million to 1.1 billion. The experience of the 20th century, when greater longevity(长寿) translated into more years in retirement rather than more years at work, has persuaded many observers that this shift(变化) will lead to slower economic growth, while the swelling(渐增的) ranks of pensioners will create government budget problems.

Policies are partly responsible. Many European governments have abandoned policies that used to encourage people to retire early. Even the better­off must work longer to have a comfortable retirement. But the changing nature of work also plays a big role. Pay has risen sharply for the highly educated, and those people continue to reap(获得) rich rewards into old age because these days the educated
