案例分析题三、某工程在实施过程中发生如下事件：事件1：由于工程施工工期紧迫，建设单位在未领取施工许可证的情况下，要求项目监理机构签发施工单位报送的《工程开工报审表》。事件2：在未向项目监理机构报告的情况下，施工单位按照投标书中打桩工程及防水工程的分包计划，安排了打桩工程施工分包单位进场施工，项目监理机构对此做了相应处理后书面报告了建设单位。建设单位以打桩施工分包单位资质未经其认可就进场施工为由，不再允许施工单位将防水工程分包。事件3：桩基工程施工中，在抽检材料试验未完成的情况下，施工单位已将该批材料用于工程，专业监理工程师发现后予以制止。其后完成的材料试验结果表明，该批材料不合格，经检验，使用该批材料的相应工程部位存在质量问题，需进行返修。事件4：施工中，由建设单位负责采购的设备在没有通知施工单位共同清点的情况下就存放在施工现场。施工单位安装时发现该设备的部分部件损坏，对此，建设单位要求施工单位承担损坏赔偿责任。事件5：上述设备安装完毕后进行的单机无负荷试车未通过验收，经检验认定是因为设备本身的质量问题造成的。问题： 对事件3中的质量问题，项目监理机构应如何处理？

An Intelligent CarDriving needs sharp eyes, keen ears, quick brain, and coordination(协调) between hands and the brain. Many human drivers have all (51) and can control a fast-moving ear. But how does an intelligent car control itself?There is a virtual(虚拟) driver in the smart car. This virtual driver has "eyes", "brains", "hands" and "feet" too. The minicameras (52) each side of the ear are his "eyes" which (53) the road conditions ahead of it. They watch the (54) to the car’s left and right. There is also a highly automatic driving (55) in the car. It is the built-in computer, which is the virtual driver’s "brain". His "brain" (56) the speeds of other moving cars near it and analyzes their positions. Basing on this information, it chooses the (57) path for the intelligent ear, and gives instructions to the "hands" and "feet" to act accordingly. In this way, the virtual driver (58) his car.What is the virtual driver’s best advantage He reacts (59) . The minicameras are bringing (60) continuously to the "brain". It completes the processing of the images with-in 100 milliseconds. (61) , the world’s best driver needs at least one second to react. Besides, when he takes (62) , he needs one more second.The virtual driver is really wonderful. He can reduce the accident (63) considerably on expressways(高速公路). In this (64) , can we let him have the wheel at any time and in any place Experts (65) that we cannot do that just yet. His ability to recognize things is still limited. He can now only drive an intelligent car on expressways. 55（）
案例分析题四、某工程，建设单位和施工单位按《建设工程施工合同 （示范文本）》签订了施工合同，在施工合同履行过程中发生如下事件：事件1：工程开工前，总监理工程师主持召开了第一次工地会议。会上，总监理工程师宣布了建设单位对其的授权，并对召开工地例会提出了要求。会后，项目监理机构起草了会议纪要，由总监理工程师签字后分发给有关单位；总监理工程师主持编制了监理规划，报送建设单位。事件2：施工过程中，由于施工单位遗失工程某部位设计图纸，施工人员凭经验施工，现场监理员发现时，该部位的施工已经完毕。监理员报告了总监理工程师，总监理工程师到现场后，指令施工单位暂停施工，并报告建设单位。建设单位要求设计单位对该部位结构进行核算。经设计单位核算，该部位结构能够满足安全和使用功能的要求，设计单位电话告知建设单位，可以不作处理。事件3：由于事件2的发生，项目监理机构认为施工单位未按图施工，该部位工程不予计量；施工单位认为停工造成了工期拖延，向项目监理机构提出了工程延期申请。事件4：主体结构施工时，由于发生不可抗力事件，造成施工现场用于工程的材料损坏，导致经济损失和工期拖延，施工单位按程序提出了工期和费用索赔。事件5：施工单位为了确保安装质量，在施工组织设计原定检测计划的基础上，又委托一家检测单位加强安装过程的检测。安装工程结束时，施工单位要求项目监理机构支付其增加的检测费用，但被总监理工程师拒绝。问题： 指出事件1中的不妥之处，写出正确做法。
下面的短文后有2项测试任务：(1)第23～26题要求从所给的6个选项中为第1～4段每段选择1个最佳标题；(2)第27～30题要求从所给的6个选项中为每个句子确定1个最佳选项。 Unlocking the Human Genome (基因组) 1 A project to unlock secrets--what scientist could resist that challenge This is what many scientists are doing as they work on the Human Genome Project. The aim of the project is to decode (破译) all of the some 100,000 genes in the human body. Scientists are using DNA fingerprinting techniques to do the decoding. 2 DNA is the substance found in the chromosomes(染色体)of a cell. A chromosome is a chain of genes. Each gene carries a piece of genetic information. At any one moment in a cell, thousands of genes are turned on and off to produce proteins (蛋白质). The challenge for scientists is to find out what role each gene plays in protein production. At some point this decoding will be complete. Then scientists will have a map of an ideal genome, or a picture of the total genetic nature of a human being. The ideal genome is called a consensus(交感)genome. Everything works well in a consensus genome. 3 But no one in the world has a consensus genome. Everyone’s genome is different from the ideal. These differences are referred to as genetic mutations(突变). Genetic mutations in a person’s genome mean that the person has a greater than average chance of suffering from health problems. Some problems are not life-threatening. These would include things like colorblindness, or mild headaches. Other problems are serious, such as heart disease or cancer. 4 It will take years to identify the role of each of the 100,000 genes. The short-term goal of the project is to find the physical and mental health problems a person is likely to encounter during his or her lifetime. The long-term goal is to have each person live a longer, healthier life. A. How does DNA work B. What is the Human Genome Project about C. How are the DNA samples collected D. What are the goals of the Human Genome Project E. What is the role of each gene F. What are the consequences of genetic mutations Paragraph 4______
Black HolesMost scientists agree that black holes exist but are nearly impossible to locate. A black hole in the universe is not a solid object, like a planet, but it is shaped like a sphere (球体). Astronomers (天文学家) think that at the center of a black hole there is a single point in space with infinite(无限的)density(稠密), This single point is called a singularity (奇点). If the singularity theory is correct, it means that when a massive star collapses, all the material in it disappears into the singularity. The center of a black hole would not really be a hole at all, but an infinitely dense point. Anything that crosses the black hole is pulled in by its great gravity.Although black holes do exist, they are difficult to observe. These are the reasons.· No light or anything else comes out of black holes. As a result, they are invisible to a telescope.· In astronomical terms, black holes are truly. For example, a black hole formed by the collapse of a giant star would have an event horizon(视界) only 18 miles across.· The nearest black holes would be dozens of light years away from Earth. One light year is about 6 trillion (万亿) miles. Even the most powerful telescopes could not pick out an object so small at such a great distance.In 1994 the Hubble Space Telescope provided evidence that black holes exist. There are still answers to be found, however, so black holes remain one of the mysteries of the universe. The sun is the heaviest star in the universe.（）
