根据以下材料,回答题:
某大型商业建筑,主体地上4层,地下1层,建筑高度23.80m,按规定设置了自动喷水灭火系统,其中地上商业均采用格栅类通透顶棚,地下车库均不设顶棚,该商业建筑在地下一层设有288m³的消防和生活合用的消防水池一座,并分成能独立使用的两个水池,水池的有效容积和补水时间均符合要求。在屋面设有消防气压给水设备配合18m³消防水箱增压,现场验收检查的照片如图2-28—1~图2-28—5所示。
请分析指出本案例图2-28-1一图2-28-5中的错误。
根据下面材料,回答题:
某商业建筑地上一层、地下一层,建筑高度为4.50m,地上主要使用性质为商业,地下主要使用性质为汽车库、设备用房和歌舞娱乐放映游艺场所。建筑防火及消防设施配置均满足现行有关国家工程建设消防技术标准的要求。
地下消防水池有效容积为350m³,屋顶高位消防水箱有效容积为18m³,由于要为自动喷水灭火系统提供其所需压力,故配设气压给水设备,型号为ZW(1)-I-z-10,其工作参数为:ρ1=0.14MPa、P2=0.21MPa、P3=0.24MPa、P4=0.29MPa。地下室设消防水泵房,消火栓系统和自动喷水灭火系统分别设消防水泵组,均为卧式离心泵,喷淋泵和消火栓泵均在水池的同一高度取水,其中自动喷水灭火系统的消防水泵流量为301/s,扬程为35m,两台同型号同规格的喷淋泵,一用一备,互为备用,均为自灌式吸水。消防水泵自灌式吸水和泵进出口附件如图2-36-1所示,该水池为生活和消防共用,在生活出水管上设有虹吸管及阀16,当水位达到水位线11处时,生活泵已不能吸水,因此水位线11以下为消防不动用容积,水池的消防不动用容积已满足室内消火栓系统2h火灾延续时间和自动喷水灭火系统1h火灾延续时间内全部消防用水量,由于室外管网能保证室外消防用水,故水池只保证室内消防用水,而且水池的补水是按补水时间不超过48h并满足生活用水量的要求设置补水设施的,补水管一根,管径DN50,湿式报警阀组设在水泵房内。
自动喷水灭火系统最不利点喷头的工作压力为0.13MPa,采用k-80喷头,喷头间距为3.4m×3.4m,配水支管及配水管管径均符合《自动喷水灭火系统设计规范(2005年版)》(GB 50084--2001)的要求。
泵出口控制阀1为明杆闸阀,泵人口阀4为对夹式蝶阀,超压泄压阀3的泄水口回流至水池,吸水管固定于池壁,吸水喇叭口置于支座上。
维保单位检查试验前,应业主要求利用本次试验的机会用消防水泵抽水将消防水池水体更换,并全面完成了消防水泵的试验工作,试验前首先检查校核了消防水池和消防水箱的有效容积,均符合设计要求;对消防水泵和气压给水设备进行了检查和试验,均能正常工作;湿式报警阀组工作正常;上下腔压力表显示正常,消防水泵出口压力表示值为0.35MPa,符合要求。试验小组决定按以下方案实施试验:
第一步,利用喷淋泵轮换工作抽水,检验喷淋泵的手动启动、自动启动、电源切换、故障互投的性能;第二步,测定喷淋泵的三点工况性能。
检查喷淋泵出水附件时发现由于超压泄压阀及管路无法进行排水,故将其拆除,另在各泵出水管处安装DN65试验放水阀,接上DN65消防水带至水坑,并将各泵的出口控制阀关闭,打开试验放水阀。另外也对消火栓泵进行同样整改。
在水泵房喷淋泵电气控制柜处手动启动A喷淋泵,泵能正常工作,压力表示值正常,消防水带出水压力稳定,运行5min后,更换8喷淋泵运行5min,接着作电源切换互投和故障互投的性能试验运行。共计运行5min后,又进入自动运行,在连续运行5min至需轮换A喷淋泵运行时,A喷淋泵尽管启动。但压力表示值为零,故停泵,立即启动B喷淋泵运行,但B喷淋泵运行情况同A喷淋泵。经检查所有电源、电气控制设备和水泵均无异样,为了排除故障又启动消火栓泵进行试验,结果同前,停止试验并测量此刻水池水位在图2-36-1中的水位线10处。
请指出本案例的图2-36-1中有什么不正确的地方。应如何正确设置,请画出图示。
More surprising, perhaps, than the current difficulties of traditional marriage is the fact that marriage itself is alive and thriving. As Skolnick notes, Americans are a marrying people: Relative to Europeans, more of us marry and we marry at a younger age. Moreover, aster a decline in the early 1970s, the rate of marriage in the United States is now increasing. Even the divorce rate needs to be taken in this pro-marriage context: some 80 percent of divorced individuals remarry. Thus, marriage remains, by far, the preferred way of life for the vast majority of people in our society.
What has changed more than marriage is the nuclear family. Twenty-five years ago, the typical American family consisted of a husband, a wife, and two or three children. Now, there are many marriages in which couples have decided not to have any children. And there are many marriages where at least some of the children are from the wife’s previous marriage, or the husband’s, or both. Sometimes these children spend all of their time with one parent from the former marriage; sometimes they are shared between the two former spouses.
Thus, one can find the very type of family arrangement. There are marriages without children; marriages with children from only the present marriage; marriages with "full-time" children from the present marriage and "part-time" children from former marriages. There are step-fathers, step-mothers, half-brothers, and half-sisters. It is not all that unusual for a child to have four parents and eight grandparents! These are enormous changes from the traditional nuclear family. But even so, even in the midst of all this, there remains one constant: Most Americans spend most of their adult lives married.
"Part-time" children______.
A:spend some of their time with their half-brothers and some of their time with their half-sisters B:spend all of their time with one parent from the previous marriage C:are shared between the two former spouses D:cannot stay with "full-time" children

Passage Three
A thief entered the bedroom of the 30th president of the United States, who met him and helped him free.
The event happened in the early morning in one of the first days when Calvin Coolidge came into power. He and his family were living in the same third-floor suite at the Willard Hotel in Washington that they had moved in several years before. The former President’s wife was still living in the White House.
Coolidge awoke to see a stranger go through his clothes, remove a wallet and a watch chain.
Coolidge spoke, "I wish you won’t take that."
The thief, gaining his voice, said, "Why"
"I don’t mean the watch and chain, only the charm. Take it near the window and read what is on its back," the President said.
The thief read," Presented to Calvin Coolidge."
"Are you President Coolidge" he asked.
The President answered "Yes, and the House of Representatives gave me that watch charm. I’m fond of it. It would do you no good. You want money. Let’s talk this over."
Holding up the wallet, the young man said in a low voice, "I’ll take this and leave everything else."
Coolidge, knowing there was $80 in it, persuaded the young man to sit down and talk. He told the President he and his college roommate had overspent during their holiday and did not have enough money to pay their hotel bill.
Coolidge added up the roommate and two rail tickets back to the college. Then he counted out $32 and said it was a loan.
He then told the young man "There is a guard in the corridor." The young man nodded and left through the same window as he had entered.
A:the former President was still living in the White House B:the former First Lady hadn't* left the White House C:the First Lady liked to live there D:he liked to live there
