     Question: I have been learning English for about 7 years.   1   And I still can't make myself understood in

English. However, I love learning English. How can I learn English well? Please help me.

     Answer: Many people have asked me this question.   2   Here I will give you several tips for learning English.

   3   

     First of all, you must want to learn. If you are not interested in learning English, no class will help you and

no book will help you. So you have to be honest with yourself. Ask yourself, "Do I really want to learn

English?" If you can't answer "yes" to this question, it is better for you to set English aside until you're ready

and willing to learn.

     Set goals(目标)

     To learn English well, you must set some goals.   4   It will also help you to see your progress. Ask

yourself,"What are my goals? What areas would I like to improve?" Think about what your goals are, and

review once in a while to see that you are making progress toward your goals.

      Practice, practice, and practice.

     After you have set your goals, you have a better idea of what you need to practice. Just like the athlete

whose goal is the Olympics must train daily, you as a language leaner must practise language every day to

make progress toward your goal.   5   

A. Want to learn.

B. I think it is not easy to learn it well.

C. Make friends with some Americans online.

D. Reading is a very good way to learn new words.

E. The answers are as different as the people asking the question.

F. The more you practise, the more progress you will make.

G. Having goals will help you remember what areas you want to work on.

某大型顶进箱涵工程为三孔箱涵，箱涵总跨度22m，高5m，总长度33.66m，共分三节，需穿越5条既有铁路站场线；采用钢板桩后背，箱涵前设钢刃脚，箱涵顶板位于地面以下0.6m，箱涵穿越处有一条自来水管需保护。地下水位于地面以下3m处。箱涵预制工作坑采用放坡开挖，采用轻型井点降水。
项目部编制了轨道加固方案，采用轨束梁加固线路，以保障列车按正常速度行驶；制定了顶进时对桥(涵)体各部位的测量监控方案，经项目部技术负责人批准后实施。
按原进度计划，箱涵顶进在雨期施工前完成。开工后，由于工作坑施工缓慢，进度严重拖后。预制箱涵达到设计强度并已完成现场线路加固后，顶进施工已进入雨期。项目部加强了降排水工作后开始顶进施工。为抢进度保工期，采用轮式装载机直接开入箱涵孔内铲挖开挖面土体，控制开挖面坡度为1:0.65，钢刃脚进土50mm；根据土质确定挖土进尺为0.5m，并且在列车运营过程中连续顶进。
箱涵顶进接近正常运营的第一条线路时，遇一场大雨。第二天，正在顶进施工时，开挖面坍塌，造成了安全事故。
问题

指出项目部编制的轨道加固与测量监控方案及实施过程存在的问题，并写出正确做法。
