When a storm is coming, most people leave the area as quickly as possible and head for safety…But there are a few people who will get into their cars and go straight for the center of the storm.These people are willing to risk being killed by floods or 100-Kilometer- an-hour winds for the excitement of watching the storm close up.

  “Storm chasing (追逐)”is becoming an increasingly popular hobby,especially in the Midwest of the United States, where there are frequent storms between March and July.A storm chaser begins the day by checking the Internet for the latest weather reports, and then drives up to l,000 kilometers to where the storm will be and waits for it to develop.

   Although anyone can do it,storm chasing is extremely dangerous.The power of a big storm  can throw a cow into the air or destroy a whole house in seconds.Storm chasers are also often hurt in accidents caused by driving in a heavy rain.If you are a beginner, it is much safer to join a group for storm - chasing vacations during the storm season.

   Even then,storm chasing is not all adventure and excitement.“Storm chasing is 95%driving,”says Daniel Lynch,who spends most of his summer storm-chasing.“Sometimes you

Can sit around for hours waiting for something to happen,and all you get is blue sky and a few light showers.”

   However,for storm chasers,it is all worth it. “When you get close to a storm,it is the most exciting sight you will ever see in your life,”says Jasper Morley.“Every storm is an example of the power of nature.It is the greatest show on Earth.”

某工程,建设单位委托监理单位承担施工阶段的监理任务,总承包单位按照施工合同约定选择了设备安装分包单位。在合同履行过程中发生如下事件:

事件1:工程开工前,总承包单位在编制施工组织设计时认为修改部分施工图设计可以使施工更方便,质量和安全更易保证,遂向项目监理机构提出了设计变更的要求。

事件2:专业监理工程师检查主体结构施工时,发现总承包单位在未向项目监理机构报审危险性较大的预制构件起重吊装专项方案的情况下已自行施工,且现场没有管理人员。于是,总监理工程师下达了《监理工程师通知单》。

事件3:专业监理工程师在现场巡视时,发现设备安装分包单位违章作业,有可能导致发生重大质量事故。总监理工程师口头要求总承包单位暂停分包单位施工,但总承包单位未予执行。总监理工程师随即向总承包单位下达了《工程暂停令》,总承包单位在向设备安装分包单位转发《工程暂停令》前,发生了设备安装质量事故。

指出事件2中总监理工程师的做法是否妥当说明理由。
