[多项选择]毕竟是中秋了，夜凉如水，不一会儿就觉得衣服有点儿潮湿，不知道是露水，是潮水的水汽，还是神话中的仙水。不知不觉已到了半夜一点钟，慢慢地听到远处有细细的声音，人们一个个从地上爬起来。大家都屏住气．用眼睛向钱塘江的水天分界处瞧去。
这时，潮水越来越大了，天边一根银色的线条，一会儿变成黑色，一会儿又变成白色，渐渐地排山倒海般由远向近而来。由于夜静，这潮水确实是比白天的大，真如千军万马，两个人面对面讲话都听不到。不知道由于心理作用还是事实如此：夜潮的潮头也高，排列也整齐；潮水到镇海宝塔下，竟成了一根笔直的线，像受检阅的部队，整齐极了，人们还舍不得离开，一直看它急流直下。这时钱塘江对岸的一排信号灯全亮了，真是夜潮更比日潮奇。

In War Made Easy Norman Solomon demolishes the myth of all independent American press zealously guarding sacred values of free expression. Although strictly focusing on the shameless history of media cheerleading for the principal post World War’ Ⅱ American wars, invasions, and interventions, he calls into question the entire concept of the press as some kind of institutional counterforce to government and corporate power.
Many of the examples compiled in this impeccably documented historical review will be familiar to readers who follow the news on the Internet. But such examples achieve flesh impact because of the way Solomon has organized and analyzed them.
