New rules and behavior standards(行为规范) for middle school students came out in March. The Middle School is going to use a new way to decide who the top students are. The best students won’t only have high marks. They should not (染) their hair, smoke or drink because they are students. The following are some of the new rules.
Have you ever copied someone else’s work in an exam Don’t do that again! That’s not something an honest student should do.
Do more at school. Good students love animals and care for other people. April is Bird-loving Month in China. Is your school doing anything to celebrate it You should join! And you can learn more about animals and how to protect them. Be friendly to the people around you. Try to think of others, not only yourself.
Be open to new ideas. Do you think people can live on the moon7 Maybe you’ll find another earth someday. Don’t look down on new ideas. Everyone’s ideas are important. You should welcome them, because new ideas make life better for everyone.
Protect yourself. Has someone ever taken money from one of your classmates Don’t let it happen to you. If you have to go home late, you should let your parents know.
Use the Internet carefully. The Internet can be very useful for students. But some things on the Internet aren’t for children, so try to look at web pages (网页) that are good for you.

某堤防工程总长为15.30km，其中新建堤防2km，起始桩号为K10+500，终止桩号为K12+500，堤身高度6.5m，按三十年一遇的防洪标准设计，主要建设内容有堤身清表、老堤加高培厚、新堤身土方填筑、填塘固基等。施工过程中发生如下事件：

事件一：工程开始前，施工单位对土料场进行了充分调查，选择具有代表性的黏性土进行碾压试验，选取三种不同的土料含水量，根据选定的碾压机械确定了含水量等土料填筑压实参数。

事件二：为加快工程进度，施工单位对新建堤防分两个作业段同时进行分层施工，每个工作面长度为1km，与老堤防接坡坡比按1：2控制。

事件三：监理机构根据料场土质情况、本工程设计标准和相关规定，分别提出新堤身土方填筑、老堤加高培厚施工土料填筑压实度、压实度合格率控制标准。
