4.根据资料（4），甲公司发出W产品会计处理的表述中，正确的是（）

某年1月3日上午，山东某化肥公司供气车间主任通知机修车间主任安排人焊接脱硫贫、富液槽蒸汽加温管。上午机修车间焊工班班长在从气车间脱硫工段长的带领下，去现场看了工作量。下午14时10分，班长安排李某、薛某、宋某到脱硫岗位焊接管线，车间安全员刘某未开具贫液槽焊接管线的动火证情况下，就开始焊接富液槽的蒸气管。

当预制好由蒸气管引出20mm的管线至富液槽锥形上盖与筒体连接处北面斜上方约400mm处时，宋某从槽顶部下来，李某、薛某2人上去，把预制好的管子进行对焊，在焊接时发生爆炸，时间是3日16时45分，富液槽锥形上盖飞出70多米，李某被抛出25米左右，薛某从槽顶部摔下地面，事故发生后，公司立即安排人将李某、薛某送往医院抢救。李某在送往医院的途中死亡，薛某腿部骨折。

                               How to Get Active Again

Getting back into exercise can be a challenge in the best of times, but with gyms and in-person exercise classes off- limits to many people these days, it can be tricky to know where to start. And it's important to get the right dose of activity. “Too much too soon either results in injury or burnout,” says Mary Yoke, PhD, a faculty member in the kinesiology department at Indiana University in Bloomington. The following simple strategies will help you return to exercise safely after a break.

41._____________________________________________.

Don't try to go back to what you were doing before your break. If you were walking 3 miles a day, playing 18 holes of golf three times a week, or lifting 10-pound dumbbells for three sets of 10 reps, reduce activity to ½ mile every other day, or nine holes of golf once a week with short walks on other days, or use 5-pound dumbbells for one set of 10 reps. Increase time, distance, and intensity gradually. “This isn't something you can do overnight,” Denay says. But you'll reap benefits such as less anxiety and improved sleep right away.

42._____________________________________________.

If you're breathing too hard to talk in complete sentences, back off. If you feel good, go a little longer or faster. Feeling wiped out after a session? Go easier next time. And stay alert to serious symptoms, such as chest pain or  pressure, severe shortness of breath or dizziness, or faintness, and seek medical attention immediately.

43._____________________________________________.

Consistency is the key to getting stronger and building endurance and stamina. Ten minutes of activity per day is a good start, says Marcus Jackovitz, DPT, a physical therapist at the University of Miami Hospital. All the experts we spoke with highly recommend walking because it's the easiest, most accessible form of exercise. Although it can be a workout on its own, if your goal is to get back to Zumba classes, tennis, cycling, or any other activ ity, walking is also a great first step.

44._____________________________________________.

Even if you can't yet do a favorite activity, you can practice the moves. With or without a club or racket, swing like you're hitting the ball. Paddle like you're in a kayak or canoe. Mimic your favorite swimming strokes. The action will remind you of the joy the activity brought you and prime your muscles for when you can get out there again.

45._____________________________________________.

Exercising with others “can keep you account able and make it more fun, so you're more likely to do it again,” Jackovitz says. You can do activities such as golf and tennis or take a walk with others and still be socially distant. But when you can't connect in person, consider using technology. Chat on the phone with a friend while you walk around  your neighborhood. FaceTime with a relative as you strength train or stretch at home. You can also join a livestream or on-demand exercise class.

【背景资料】
某大(2)型水库枢纽工程，总库容为5.84×10⁸m³，水库枢纽主要由主坝、副坝、溢洪道、电站及输水洞组成。输水洞位于主坝右岸山体内，长275.0m，洞径4.0m，设计输水流量为34.5m³/s。该枢纽工程在施工过程中发生如下事件：
事件1：主坝帷幕由三排灌浆孔组成，分别为上游排孔、中间排孔、下游排孔，各排孔均按二序进行灌浆施工；主坝帷幕后布置排水孔和扬压力观测孔。施工单位计划安排排水孔和扬压力观测孔与帷幕灌浆同期施工。
事件2：输水洞布置在主坝防渗范围之内，洞内采用现浇混凝土衬砌，衬砌厚度为0.5m。根据设计方案，输水洞采取了帷幕灌浆、固结灌浆和回填灌浆的综合措施。
事件3：输水洞开挖采用爆破法施工，施工分甲、乙两组从输水洞两端相向进行当两个开挖工作面相距25m，乙组爆破时，甲组在进行出渣作业：当两个开挖工作面相距10m，甲组爆破时，导致乙组正在作业的3名工人死亡。事故发生后，现场有关人员立即向本单位负责人进行了电话报告。

某云计算数据中心项目规划用地20亩，总建筑面积2.5万m2，设计机柜3438台，按国家A级标准建设，概算投资5.03亿元。A公司作为总承包单位承接该项目机电安装工程，工程内容包含一栋四层数据中心大楼、室外柴发机组、埋地储油罐、雨水调蓄池等。由于工期紧张，A公司经监理公司同意，将数据中心大楼的通风空调安装工程分包给B公司。在B公司进场前，A公司已经完成了所有土建、电气等相关专业的预留工作。
在空调安装工程施工过程中，监理工程师指出B公司制冷机组的安装存在问题，如下图。
B公司项目部经过讨论，认为施工图中水冷机组安装基础的预留位置以及相关的压力管道布置不合理，无法继续按图施工，故向监理单位提出设计变更并征得业主同意。拿到变更图纸后，B公司加快施工进度，在目标工期截止日前将各分项工程施工完毕。并在电动机、压缩机、水泵等动设备及辅助系统、控制系统试运行全部合格，联动试运行合格后，A公司组织编制了负荷试运行规程并报监理单位审批，监理单位拒绝A公司的申请。
