A student newspaper reports that most students go to sleep at 1:30 am. Even if that’s an overstatement (夸张), it’s close to the truth. Scientists say teens should sleep nine hours each night. But that’s hard. Some are even “pulling all-nighters” (开夜车). These students must hand in their homework the next day but they haven’t done it. In the morning they don’t look healthy and you can tell who’s been doing it. One of my classmates did a survey on the topic. She found that most kids pull all-nighters to finish homework, but some do it for other reasons, such as playing computer games!

Maybe our lack(缺乏) of sleep is because of laziness — I think I’m a rather lazy student — or maybe it’s because we have too much to do in American high schools. I usually go to bed around midnight. If I stayed up past 1:30 am, I wouldn’t get any work done. I’d be falling asleep at my computer. My classes begin at 7:30 am. I’m partly awake in my first class. By the second, I’m a little sleepy. By my third class, I’m sleepy. By midday I’m finally fully awake. But by 3:00 pm, I’m slowing down again. Yet I get more sleep than usual students.

Most American high schools seem to have a similar(相似的) problem with sleepy students. High school classes start at 7:30 am, so students have to get up one and a half hours before that to get ready and catch the bus. It’s believed that lack of sleep can be bad for both grades and health. Some schools are paying attention. Classes in those schools start at 8:30 am.

A.They play computer games.

B.They watch videos late.

C.They have to do a lot of housework.

D.They have to do a lot of homework.小题3:When do students in most American high schools have to get up?

A.At 7:30 am.

B.At 6:00 am.

C.At 9:00 am.

D.At about 7:00 am.小题4:Which of the following is TRUE according to the reading?

A.The writer usually stays up past 1:30 am.

B.The writer usually goes to bed around midnight.

C.The writer usually does a survey.

D.Many American students don’t get enough sleep, so they can have high grades.小题5:What’s the main idea of the passage?

A.Something has to be done to solve the problem of students’ lack of sleep.

B.Many American high school students are sleepy in class.

C.Many kids have too much homework to do.

D.Students can’t play computer games.

问答题 案例分析题

某施工单位承接了二级公路施工,K20+300处有一座主跨为5×30m预应力混凝土简支空心板梁桥,中间桥墩均为水中墩,上部结构采用预制吊装,梁体采用后张法施工,制梁厂设在一侧桥头挖方路基上。

事件一:施工单位为保证测量工作的质量,提高测量工作效率,在测量工作的各个程序中实行双检制,制订了以下测量管理制度:

制度一:测量队应核对有关设计文件和监理签认的控制网点测量资料,应由两人独立进行,核对结果应作记录并进行签认,成果经项目技术部门主管复核签认,项目生产副总审核签认后方可使用。

制度二:一切原始观测值和记录项目在现场记录清楚,如果书写错误必须用涂改液进行涂改。

制度三:测量外业工作必须有多余观测,并构成闭合检测条件。控制测量、定位测量和重要的放样测量必须坚持“两人两种方法”制度,坚持采用两种不同方法(或不同仪器)或换人进行复核测量。利用已知点(包括平面控制点、方向点、高程点)进行引测、加点和施工放样前必须坚持“A”的原则。

测量后,测量成果必须采用两组独立平行计算进行相互校核,测量队长、测量组长对各自的测量成果进行复核签认。

事件二:预应力张拉。将钢绞线穿入波纹管道内(钢绞线下料长度考虑张拉工作长度),进行张拉作业。张拉使用的张拉机及油泵、锚、夹具必须符合设计要求,并配套使用,配套定期校检,以准确标定张拉力与压力表读数间的关系曲线。

按设计要求在两端同时对称张拉,张拉使的千斤顶的作用线必须与预应力轴线重合,两端各项张拉操作必须一致。预应力张拉采用“双控”。

事件三:施工单位在张拉过程中第2片梁的张拉过程中,出现钢绞线的断丝现象,据统计,断丝数量超过设计规定的允许数量。

事件四:施工单位购买了定型钢模、脚手架等,并按周转材料的管理制度进行日常使用和管理。

对于定型钢模的价值摊销,施工单位采用一次摊销法进行。

写出事件二中双控的具体做法。
