题目内容

某日上午10：30左右，监控中心收到报警，发现F座10楼厨房附近窗户有浓烟冒出。监控中心立即通知安防员携带消防工具赶到现场，并及时关闭了F座10楼的电源总开关及燃气总阀，来到单元门口时正遇业主返回，便协助业主迅速打开房门，此时屋内烟雾较大，厨房基本已经被浓烟覆盖。安防员迅速打开各窗户，在做好自我防护措施后进行灭火操作。事后确定是微波炉短路引发火灾。由于发现及时，当值安防员在监控中心指挥下，快速赶到事发地将火扑灭。此次火灾烧毁了部分橱柜及一些餐具等，部分天花板被熏黑。由于扑救及时，未对业主财产造成更大损失。根据以上案例，回答1~4题：一些事件，在物业管理服务活动过程中突然发生，而且需要立即处理，试分析这些紧急事件具有哪些性质？

听力原文： Despite widespread medical opinion that alcoholic beverages may prevent heart disease, a leading medical expert is advising: don't start drinking just yet.
Anybody who's ever worked in a hospital sees the hospital is full of patients that have alcohol related disease, but the hospital is not full of patients that have disease related to cholesterol and blood pressure-lowering medicines.
In an editorial in the current New England Journal of Medicine, Dr. Goldberg of Columbia University said it is time to see whether alcohol actually prevents heart disease. Such a study would give alcoholic beverages to one group of heart disease patients and not to another, and see which does better.
In the latest study, which followed a group of men over a 12-year period, researchers found that those who drank three or more drinks per week reduced their risk of heart attack by 35 percent compared to abstainers.
The lead author, physician Kenneth Mukamal of Beth Israel Deaconess Medical Center in Boston, insists his study is different from the rest. For one thing, other studies have not looked at drinking patterns.
Dr. Mukamal says his findings also appear to settle which alcoholic beverages are most heart healthy. "Beer and spirits, beer and liquor, were most strongly associated with reduced risk."

乡下老家前面的空地，租给人家种桃花心木的树苗。树苗种下来后，植树人总是隔几天才来浇水。他来的天数并没有规则，有时三天，有时五天，有时十几天来一次。浇水的量也不一定，有时浇得多，有时浇得少。桃花心木有时就莫名地枯萎了，所以，他来的时候总会带几株树苗补种。我起先以为他太懒，隔那么久才为树浇水。但是，懒的人怎么会知道有几棵树枯萎了呢？他说：“种树是百年基业，所以树木自己要学会在土地里找水源。我浇水只是模仿老天下雨，老天下雨是算不准。如果无法在这种不确定中汲水生长，树苗很自然就枯萎了。但是，只要在不确定中找到水源，拼命扎根的树，长成百年的大树就不成问题了。”
