That golden sea with dazzling waves,mountain-high-an immensity of wheat field for t hree days fly,where my fat her stands sho ulder high,my elder brot herexpo sing only his head,my granny falling into t he sea up2o n her t read,above me golden billows surging like a crestof a hundred feet and I hold my breat h,jumping twotimes and t hree,which ends in a failure to reach t he earsof wheat.

这是一段关于麦田的生动描写。作者使用夸张的修辞手法把人在麦浪中的情景描绘得出神入化。在此段的一开始，作者就用&golden sea&描绘出麦田的色彩，用&mountain high&比喻麦子的高度，紧接着又用了&for three days&的数字夸张手法描绘出麦田的浩瀚无垠。

The macroscopic shrinkage of cementitious materials often causes cracking when it is used as paving material and reduces its durability.

水泥基路面材料在使用过程中常会发生明显的体积收缩趋势，在结构中引起收缩裂缝，降低路面结构耐久性。

A new defluorination idea is presented. During the process of producing phosphoric acid with chlorhydric acid and phosphate rock, the extraction reaction of the phosphate rock is accompanied with the defluorination reaction. Feed-grade calcium hydrogen phosphate according with international standard can be made by filter and neutralization without any deflourination agent.

采用全新的脱氟理念，在使用盐酸与磷矿制取磷酸的过程中，磷矿的浸取反应与除氟反应同步进行，在不添加任何除氟剂的条件下，浸取液经过过滤，中和，就可以制出符合国标要求的饲料级磷酸氢钙。

4 All exposed dead metal parts of a cord-connected appliance that is equipped with a grounding conductor, and all dead metal parts within the enclosure that are exposed to contact during any user servicing and are likely to become energized, shall be conductively connected to the grounding conductor of the power-supply cord.

27.4一个有接地导体的线连接电器的所有的外露金属件及在外壳内外露且用户在使用过程中可能触及的带电固定金属件，都应同电源线的接地导体相连。

They've learned basic sign language in laboratories, and in nature, they exhibit tool use, fashioning sticks to dig for termites and grubs, smashing nuts with rocks, and crumpling leaves to collect water.

在语言实验室里，他们可以掌握简单的语言。在大自然中他们能够使用工具，例如用木棍钓白蚁或掏可以食用的幼虫，用石头砸开坚果，用树叶收集饮用水。

After the click reaction of the SCL micelles and azide-terminus PNIPAM homopolymer, the novel PNIPAM-functionalized SCL micelles with pH-responsive cores and outer thermosensitive coronas were prepared, which was investigated act as excellent candidate of nanosized drug delivery vehicles. Finally, two types of novel shell cross-linked micelles in aqueous solution were prepared from these remarkable PMEO_2MA-b-P(DMA-co-QDMA)-b-PDEA triblock copolymers by cross-linking the inner P(DMA-co-QDMA) shell of micelles upon the addition of diazide tetra derivative in the presence of copper catalyst using click chemistry.

另外，还可以使用溴丙炔对ATRP聚合出的PMEO_2MA-b-PDMA-b-PDEA三嵌段的中间PDMA嵌段进行部分季胺化，这样可以利用两端叠氮化的四甘醇来交联由PMEO_2MA-b-PDMA-b-PDEA在不同条件下形成的两种分别以PMEO_2MA或PDEA为核的胶束，从而实现了从同一个聚合物直接在水溶液中得到两种内核不同敏感的壳交联胶束。
