案例四   【背景资料】   某安装公司承接一商务楼(地上30层、地下2层)的电梯安装工程,工程有32层32站曳引式电梯8台,工期为90天,开工时间为3月18日,其中6台 客梯需智能群控,2台消防电梯需在4月30日交付使用,并通过消防验收,在工程后期作为施工电梯使用。电梯井道的脚手架、机房及层门预留孔的安全技术措施 由建筑公司实施。   安装公司项目部进场后,将拟按照的电梯工程,书面告知了电梯安装工程所在地的特种设备安全监督部门,并按合同要求编制了电梯施工方案和电梯施工进度计 划(见表4)。电梯安装前,项目部对机房的设备基础、井道的建筑结构进行检测,土建施工质量均符合电梯安装要求:曳引电机、轿厢、层门等部件的安全技术要 求,消防点滴施工进度计划完成,并验收合格。   施工进度到客梯单机试运行调试时,有一台客梯轿厢晃动厉害,经检查时候导轨的安装精度没达到技术要求,安装人员对导轨重新校正固定,单机试运行合格, 但导轨的校正固定,使单机试运行比原工序多用了3天,其后面的工序(群控试运行调试、竣工验收)均按工序时间实施,电梯安装工程比合同工期提前完工,交付业主。

   【问题】

消防电梯从开工到验收合格用了多少天?电梯安装工程合同比合同工期提前了多少天?

答案

参考答案:

通过电梯施工进度计划图可知,消防电梯的验收合格时间是4月21日,而工程的开工时间是3月18日,按照日历3月、5月都应该是31天,不过电梯施工进度 计划图中显示5月份是30天,所以此题应该是按照每月30天考虑的,所以消防电梯从开工到验收合格共用了13+21=34天。由于题目已知单机试运行比原 工序时间多用了3天,所以其紧后工序群控试运行调试就推迟了天开始,导致最后竣工验收比原工序事件推迟了3天,所以电梯安装工程实际的结束时间是6月3 日。由于开工时间是3月18日,合同工期是90天,合同工期的竣工时间应该是6月17日,因此实际竣工时间比合同工期提前了14天。

阅读下列应用文及相关信息,并按照要求匹配信息。请在答题卡上将对应题号的相应选项字母涂黑。

以下是五位专家的建议。请匹配这些建议及对应的生活感想或经验介绍(A、B、C、D、E和F)。选项中有一项是多余选项。

小题1:You should watch where your weight accumulates.You can use the waist to hip ratio to find if there is too much fat around the middle.Belly fat is especially dangerous because it release free fatty acids directly to the liver, virtually flooding it with fat.

小题2:If a particular food is important to you, eat it, but work it off.You should try to learn the art of compromise.

小题3:At the same time.the three-for-one is relatively simple to use.Fat grams and calories are listed on almost all boxed, canned or packaged foods —— you have only to read the label and follow the rule.A five-year-old patient of mine can do this.

小题4:Drinking water is basic, and drinking enough of it is necessary.Patients are sometimes surprised that basic things work when they do them consistently.

小题5:Consume antioxidant foods.They protect the cholesterol(胆固醇), from oxidative damage, which helps prevent damage to blood…vessel walls.

A.More than nine years ago I was 70 pounds overweight and wore a very big dress.I had tried different diets and lost weight only to gain it back.Finally a simple “three-for-one’’ fat rule worked for me:consuming no more than three grams of fat for every 100 calories per serving.Following the rule and eating only foods that contain less than 30 percent fat, I spent eight months getting down to a size seven, and I’ve kept the weight off for nine years.

B.And for foods that aren’t packaged, you rely on what we already know about them.Red meat, as well as dishes made or served with butter, gravy, cream sauce or cheese, are almost never less than 30 percent fat——so you just don’t eat them.On the other hand, some non-packed foods——all fruits and vegetables except avocadoes and olives——always pass the test.So do most fish, but not when fried.

C.I like vegetables, which are rich in vitamins.Most foods containing vitamins C and E(such as sweet potatoes, tomatoes, spinach and broccoli)are low in calories and are known as antioxidants(抗氧化物质).They can help reduce the possibility to develop hardening the arteries(动脉).

D.I gain weight around the belly—what we call abdominal obesity, the worst kind.The tendency seems to be hereditary(遗传的), and it’s common among men.This problem increases the risk of a stroke or heart attack.A guide I use in estimating belly fat is the waist-to-hip ratio or WHR.To find yours, divide the circumference(周围)of you waist by the circumference of you hips.Women with ratios above 0.8 and men with ratios above 1.0 are at increased health risk.E.My ways of keeping healthy are very simple, and they are among our everyday activities:eating healthy food and doing exercise.In addition, I manage to do those basic things, such as drinking water, sleeping well and eating less fat.Sometimes I do some of the other things I used to do in my life like walking for half an hour a day.

F.Although I've put on ten pounds.I'm healthy and in good shape.I eat food that’s good for me…but I work off Susan’s homemade brownies(巧克力蛋糕), for example.To offset these extra calories, I walk for an hour or more, three times a week…often with Susan.We’re both busy and this is one way we have some quiet time together.Equally important, it permits me to practice dieting fine art of compromise.
