某市大学城园区新建音乐学院教学楼,其中,主演播大厅层高5.4m,双向跨度19.8m,设计采用现浇混凝土井字梁。 施工过程中,发生了下列事件: 事件一:模板支撑方案经施工单位技术负责人审批后报监理工程师签字,监理工程师认为其支撑高度超过5m,需组织专家进行论证。 事件二:按监理工程师提出的要求,施工单位组织成立由企业总工程师、监理、设计单位技术负责人以及外单位相关专业共计七人组成的专家组,对模板支撑方案进行论证。专家组口头提出论证意见后离开,论证会结束。 事件三:上级单位在安全文明施工检查时发现,警示牌悬挂比较随意,有的比较隐蔽,有的甚至没有针对性,随后对项目提出了整改意见,要求严格按标准进行设置。 事件四:施工过程中,因西侧模板支撑系统失稳,发生局部坍塌,造成东侧刚浇筑的混凝土顺斜面向西侧流淌,致使整个楼层因失稳而相继倒塌。整个事故未造成人员死亡.但重伤9人,轻伤14人,估计直接经济损失达1300万元。事故发生后,施工单位立刻向相关部门报告事故发生情况。 事件一中,监理工程师说法是否正确,说明理由。该方案是否需要组织专家进行论证,说明理由。

Today ,as in every other day of the year ,more than 3000 U.S. adlescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime,it can be expected that of these 3000 about 23 will be murdered,30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths attributed to cigarette smoking outweithts all other factors, whether voluntary or involuntary, as a cause of death. Since the late 1970s, when daily smoking among high school seniors reached 30 precent , smoking rates among youth have declined . While the decline is impressive ,several important issues must be raised. First, in the past several years,smoking rates among youth have declined very little. Second,in the late 1970s ,smoking among male high school seniors exceeded that among female by nearly 10 percent . The statistic is reversing.Third ,several recent studies have indicate high school dropouts have excessively high smoking rates, as much as 75 percent . Finally, thouth significant declines in adolescent smoking have occurred in the past decade,no definite reasons for the decline exist. Within this context,the Naional Cancer Instiute (NCI) began its current effort to determine the most effecive measures to reduce smoking levesl among youth. What is implied but not stated by the author is that ().

A. smoking rates among youth have declined very little
B. there are now more female than male smokers among high school seniors
C. high smoking rates are due to the incease in wealth
D. smoking at high school are from low socio-economic background

材料一:党的策略路线,是在发动、团结与组织全中国全民族一切革命力量去反对当前主要的敌人——日本帝国主义与卖国贼蒋介石。 ——摘自《中共中央关于目前政治形势与党的任务决议》(1935年12月25日) 材料二:在民族危机日趋严重、全国抗日浪潮不断高涨的形势下,1936年7月1—3日蒋介石在国民党五届二中全会上曾表示要“御侮救亡”。对此,沈钧儒等人发表如下声明: “蒋先生处全国最高统治地位,应该赶快设法,作抗日救亡的真正准备。真正的准备抗日,决不是所谓‘先安内后攘外’,而是联合各党各派,开放民众运动以共纾国难。” ——沈钧儒等《团结御悔的几个基本条件与最低要求》(1936年7月15日) 材料三:目前中国人民的主要敌人,是日本帝国主义,所以把日本帝国主义与蒋介石同等看待是错误的,“抗日反蒋”的口号,也是不适当的。在日本帝国主义继续进攻,全国民族革命运动继续发展的条件下,国民党中央军全部或其大部有参加抗日的可能。我们的总方针应是逼蒋抗日。 ——摘自《中共中央关于逼蒋抗日问题的指示)(1936年9月1日) 在材料一中,中国共产党为什么把蒋介石看作当时的主要敌人之一?
