问题 单项选择题

某工程业主与承包商签订了工程施工承包合同。合同工期5个月，工程量预估为10000m3，合同单价为100元/m3。预付款30%，从第一个月起每月等比例扣除。工程保留金按工程进度款的5%逐月扣留，监理工程师每月签发进度款的最低限额为10万元(且为整数万元)，不足10万元转入下月。计划每个月匀速施工，但第1个月、第2个月实际完成的工程量分别为1600m3和2000m3。合同约定：当累计实际完成工程量超过(或低于)估算工程工程量的10%时，可进行调价，调价系数为0.9(或1.1)。工程竣工时，经工程师计量累计完成工程量为13000m3。为有效控制成本，该工程每月进行成本分析。
根据材料，回答以下问题：

( )签字后，建设单位拨付工程款，进行竣工验收。

A．旁站监理
B．监理工程师
C．总监理工程师
D．业主代表

答案

参考答案：C

解析： 本题考核的是1Z201102监理的工作任务。未经监理工程师签字，建筑材料、构配件和设备不得在工程上使用或者安装，施工单位不得进行下一道工序的施工。未经总监理工程师签字，建设单位不拨付工程款，不进行竣工验收，监理工程师有全权禁止不符合质量要求的材料和设备进入工地和投入使用。

单项选择题

The idea of test-tube babies may make you either delighted at the wonders of modem medicine or irritated while considering the moral, or legal, or technological implications-of starting life in a laboratory. But if you’ve ever been pregnant yourself, one thing is certain: You wonder what it’s like to carry a test-tube baby. Are these pregnancies normal Are the babies normal
The earliest answers come from Australia, where a group of medical experts at the Queen Victoria Medical Center in Melbourne have taken a look at the continent’s first nine successful invitro pregnancies. The Australians report that the pregnancies themselves seemed to have proceeded according to plan, but at birth some unusual trends did show up. Seven of the nine babies turned out to be girls. Six of the nine were delivered by Caesarean section. And one baby, a twin, was born with a serious heart defect and a few days later developed life-threatening problems.
What does it all mean Even the doctors don’t know for sure, because the numbers are so small. The proportion of girls to boys is high, but until there are many more test-tube babies no one will know whether that’s something that just happened to be like that or something special that happens when egg meets sperm in a test tube instead of a fallopian tube. The same thing is true of the single heart defect. It usually shows up in only 15 out of 60,000 births in that part of Australia, but the fact that it occurred in one out of nine test-tube babies does not necessarily mean that they are at special risk. One thing the doctors can explain is the high number of Caesareans. Most of the mothers were older, had long histories of fertility problems and in some cases had had surgery on the fallopian tubes, all of which made them likely candidates for Caesareans anyway.
The Australian researchers report that they are quite encouraged. All the babies are now making normal progress, even the twin with the birth defects.
