背景材料：
某一级公路全长55.28km，双向4车道，路幅宽24.5m，设计车速80km/h，路面基层为水泥稳定土无机结合料基层，根据工程实际情况及施工单位人力、设备条件，施工单位采用了路拌法水泥稳定土基层施工工艺。摊铺水泥日进度1.5km(单向)，K5+700～K10+700路段具体施工过程如下：
(1)施工放样，恢复中线；根据施T布料需要在下承层上划布料网络。
(2)对水泥稳定土基层施工所需的土料、集料、水泥等按要求进行备料。
(3)确定松铺系数后，施工单位共用5d时间完成摊铺土任务。某日摊铺土2.5km。
(4)按规定洒水闷料，整平轻压。
(5)按规定摆放水泥，用刮板将水泥均匀摊开。
(6)为保证拌合质量，按规定采用了稳定土拌合机进行拌合。为了避免损坏下承层，拌合深度保持在下承层顶面5～10mm。
(7)拌合料拌合均匀后，立即用平地机初步整形，为保证整形质量，全路段平地机均由两侧路肩向路中心进行刮平。
(8)整形后，当混合料的含水量为最佳含水量(±1%～±2%)时，按规定用轻型压路机配合12t以上的压路机进行碾压。直线和平曲线段，由两侧路肩向路中心碾压，设超高的平曲线段，由外侧路肩向内侧路肩碾压。
2．问题：
(1)本项目路拌法水泥稳定土基层施工准备中少了什么重要环节？并简述这一环节主要工作。
(2)请指出本项目具体施工过程中存在的问题，并进行改正。

The Americans believe that anybody can become President of the United States. In a recent Hollywood comedy（喜剧）, that is exactly what happens.

Dave Kovic, played by Kevin Kline, is a kind-hearted man who runs a business that finds people jobs. He leads a typical（典型的） American way of life, except for one thing－he looks exactly like the President, Bill Mitchell. In fact, the only thing that makes him different from the nation’s leader is that he is very nice!

The president has started using look-alikes during some public appearances. Dave is offered a chance to “serve his country” by becoming one. However, things go wrong. The President becomes very ill and Dave ends up acting as the President forever.

Director Ivan Reitman, who made the popular and successful comedies like Twins, Ghostbusters and Legal Eagles, could have gone for easy laughs by making fun of the American government. Instead, Dave is an attractive comedy about an ordinary man in extraordinary situations. Kevin Kline gives a double performance as Dave and the President, and Sigourney Weaver is at her best as his First Lady. The love story that develops between her role and Dave is a real classic（经典）.

The film is 100% American. However, if you’ve ever felt that anybody could do a better job running the country than the people in power, then you’ll enjoy Dave!
