24、s each time.FGet your friends to remind you if youve been on for a long time.GAlso，it is a good place to get some good books and magazines to read.文章大意：随着互联网技术的发展，我们对网络的依赖程度逐渐加大。网瘾已成为阻碍许多人正常生活的障碍。我们应该趋利避害，合理控制上网时间。解析：1后文主要讲许多人饱受网瘾折磨，不能集中精力完成生活中于他们而言重要的事情，C 项“网瘾影响许多人”总领该段。2前一句提到，承认你有网瘾。B 项“避而不谈这个事实并没
25、有用”承接上文。3该段主要讲缩短玩电脑的时间，E 项“尝试每次缩短 5 分钟时间”符合语境。4该段句首提到，尝试着在图书馆里上网。紧接着解释原因，G 项“那也是一个读好书及杂志的地方”是原因之一，也符合图书馆的特点。5该段主要讲要与朋友一起跑步或用其他方式锻炼，关心小区的事件，如讲座、电影、音乐会、体育事件等，这些都可以不用上网，故 A 项“培养爱好或者兴趣”符合该段主旨。.语法填空阅读下面短文，在空白处填入适当内容(1 个单词) 或括号内单词的正确形式。Once James Thornhill，a famous English painter，was asked_1.to_paint_(pa
26、int)some pictures on the walls of the kings palace in England.Then_2.workers_(worker)were sent for and a big platform was made._3.With_the help of a worker，Thornhill started painting on the platform.They worked for a whole year and at last the pictures_4.were_(be) ready.Thornhill was happy when he l
27、ooked at the pictures，for they were_5.really_(real) beautiful.He looked at them for a long time，and then took one step back and looked again.Now the pictures were even_6.more_beautiful_(beautiful)He took another step，then another.Finally he was at the very edge of the platform，but he did not know it
28、 because he was thinking of his pictures._7.The_worker saw everything.“What should I do？” he thought.“Thornhill is at the very edge of the platform.If I cry out，he will take another step，fall off the platform and surely be killed.” So the worker quickly took some paint and threw_8.it_at the picture.
29、The picture_9.was_ruined_(ruin) at once.“What are you doing？” cried the painter，_10.running_(run) quickly forward to his pictures.解析：1ask 后接带 to 的不定式作宾语，ask sb.to do sth.“要求某人做某事” ，此处是其被动结构。2根据空格后的谓语动词 were sent 可知，worker 应用复数形式。3with the help of.“在的帮助下” ，是固定短语。4根据语境，此处是讲述过去的事情，应用一般过去时；主语是复数名词，故填were。5修饰形容词 beautiful，作状语，应用副词。6句意为“现在那些画甚至更美了” ，暗含比较意义，故用比较级。7特指前文提到的那位工人，故用定冠词。8作 threw 的宾语，指代 some paint，故用 it。9the picture 与 ruin 之间是被动关系，且应用一般过去时，故填 was ruined。10the painter 与 run 是主动关系，故用现在分词，作状语。
