试题解析

釉质

又称珐琅质,为牙齿外露部分之白色致密而非常坚硬之物质,其实质为羟磷灰石的钙化性外被,起复盖和保护牙齿的作用。釉质中含有一定量的微量元素氟,氟可取代珐琅质中一部分羟磷灰石的羟基,形成不易溶于酸的结晶,可增强牙齿对口腔微生物形成的酸的抵抗力,使珐琅质不易被侵蚀而造成龋齿。但氟过量引起的氟中毒可导致釉质的破坏,使牙齿表面失去光泽,出现灰色斑点,称之为斑釉牙。齿冠表面的一层硬的组织。其主要成分为碳酸钙、磷酸钙,还含有氟和一些有机质。也叫珐琅质。

In this section, there is one passage followed by a summary. Read the passage carefully and complete the summary below by choosing no more than four words from the passage. Remember to write the answers on the Answer Sheet.  As a result of all these factors, when the recession eases and people find more confidence, there will be an explosion of employees seeking new opportunities to escape their current jobs. This will be led by younger, less-experienced employees and the hard - headed young graduates. ‘Headhunters’ confirm that older staff are still cautious, having seen so many good companies ‘go to the wall’, and are reluctant to jeopardize their redundancy entitlements. Past experience, however, suggests that, once triggered, the expansion in recruitment will be very rapid.  The problem which faces many organizations is one of strategic planning; of not knowing who will leave and who will stay. Often it is the best personnel who move on whilst the worst cling to the little security they have. This is clearly a problem for companies, who need a stable core on which to build strategies for future growth.

They have only known recession and lack the experience to plan ahead and to implement strategies for growth.
