《住宅装饰装修工程施工规范》(GB50327—2001)规定:8.3.1龙骨的安装应符合下列要求,1.应根据吊顶的设计标高在四周墙上弹线。弹线应清晰、位置应准确。2.主龙骨吊点间距、起拱高度应符合设计要求。当设计无要求时,吊点间距应小于 1.2m,应按房间短向跨度的1‰~3‰起拱。主龙骨安装后应及时校正其位置标高。3.吊杆应通直,距主龙骨端部距离不得超过300mm。当吊杆与设备相遇时,应调整吊点构造或增设吊杆。4.次龙骨应紧贴主龙骨安装。固定板材的次龙骨间距不得大于 600mm,在潮湿地区和场所,间距宜为300~400mm。用沉头自攻钉安装饰面板时,接缝处次龙骨宽度不得小于40mm。5.暗龙骨系列横撑龙骨应用连接件将其两端连接在通长次龙骨上。明龙骨系列的横撑龙骨与通长龙骨搭接处的间隙不得大于1mm。6.边龙骨应按设计要求弹线,固定在四周墙上。7.全面校正主、次龙的位置及平整度,连接件应错位安装。

第二节:读写任务(共1小题,满分25分)

阅读下面的短文,然后按照要求写一篇150词左右的英语短文(包括短文概括和议论文)

The Importance of a Good Education

Getting a good education may be the most important price you can pay, because, perhaps more than anything else, what you do with that huge gray material between your ears will determine your future. These words actually describe millions of people worldwide who choose to limit their potential ability by not widening their education.

A person is much more likely to have better job offers, more successful career with a better education. This, in turn, would allow for much better life style. For example, compare two men. The first person is a high school dropout. The second has a law degree. The high school dropout will be fortunate to get a job in food services, making less than twenty thousand dollars a year, barely surviving each week. To contrast this, the person with the law degree will certainly have a successful career as a lawyer, making over $ 70,000 annually. The lawyer will, of course, have a very wealthy lifestyle. Statistics show that high school dropouts make 42% less money than college graduates.

Our generation will become doctors, lawyers, teachers and leaders of tomorrow. To do this successfully, a higher level of education is very important! We must crave learning. This, in turn, will pay for not only our future but also will help to insure success for those who follow.
