分析：考点是冠词的用法。最高级前面必须加定冠词the，答案D。

Crown ether was introduced to copolymerize with the monomer of styrene owing to which can associate with silver ions. The silver ions were in-situ reduced to silver nanoparticles by UV light. Then silver nanoparticles were led on the surface of polystyrene latex particles. The vertical precipitation was employed to get the spheres self-assembled into close packed colloidal crystal with a face centered cubic structure identified.

利用冠醚可与银离子复合的特性，制备了聚苯乙烯－冠醚乳胶粒，采用原位还原的方法在乳胶粒表面引入银纳米颗粒，通过垂直沉降，乳胶粒子可自组装成紧密堆积具有面心立方的聚苯乙烯－银胶体晶体。

The raw data was processed by using axial, coronal and double oblique multi-planar reformation; Images obtained were graded in terms of quality with a 5-point scale(5=excellent, 4=good, 3=fair, 2=poor, and 1=nondiagnostic). In grading image quality at axial MPR, The radiologic specialists focused on the subarcuate fossa, tendon of tensor tympani, facial recess, vestibular aqueduct and pyramidal eminence, In grading image quality at coronal MPR, attention was given to the scute, crista transversa, fenestra cochleae, lateral malleal ligament and snake eyes signature of cranial nerve, In the grading of the image quality at double oblique MPR, the radiologic specialists concentrated on the malleus, incus, stirrup bone, upper bony semicircular and aquaeductus fallopii, and then to implement statistical analysis. In order to choose the minimum tube current values and the maximum pitch that can satisfy the diagnosis request, image quality of axial, coronal and double oblique reformation images was compared with different tube current groups. 15 ears of volunteers were used to test the validity with the scanning parameter. Subsequently noise, MTF and dose length product were measured by phantoms in different tube current and pitch, the parameters obtained were compared and taken into statistics analysis.

扫描模式使用临床常用的颞骨螺旋扫描方式：管电压120 kV，准直宽度20×0.6 mm，视野200 mm，重建矩阵512×512，旋转时间1 s/r，重建层厚0.6 mm，重建间隔0.3 mm，分别改变管电流(380、300、200、160、120和80 mA)和螺距(0.8、1.0和1.2)进行扫描和重建，然后对颞骨进行横断面、冠状面和双斜面多平面重组，于重组后的横断层面图像上选取弓形下窝、鼓膜张肌腱、面神经隐窝、前庭导水管和锥隆起5个解剖结构，冠状面重组图像上选取盾板、横嵴、蜗窗、面神经的蛇眼征和锤骨外侧韧带5个解剖结构，双斜面重组图像上选取锤骨、砧骨、镫骨、上骨半规管和面神经管5个解剖结构，在双盲的情况下由放射学专家分别对各管电流和螺距下扫描的重组图像进行评分，随后进行统计学处理，从中筛选出满足诊断要求的最低管电流值和最大的螺距，分别采用患者25例(15耳)用该管电流值和螺距验证其可行性；然后利用模体分别测试各管电流和螺距下的图像的空间分辨率、噪声及其剂量长度积，并对测试所得参数数值进行比较和统计学处理。

In the presence of NaH and in DMF, the acyclic crown ethers 1a and 1b were synthesized by the reaction of di-or triethyleneglycol ditosylate and o-methoxymethoxybenzyl alcohol, which was obtained from salicylaldehyde via the protection of the hydroxyl group with chloromethyl methyl ether followed by the reduction of the formyl group with NaBH4. The hydrolysis of 1a and 1b with dilute hydrochloric acid provided the diphenolic type acyclic crown ethers 2a and 2b respectively in good yield.

将水杨醛与碱和氯甲基甲基醚反应，再经过NaBH4还原，即制得邻苯甲醇，然后将其在DMF中与NaH和二甘醇二对甲苯磺酸酯反应，得开链冠醚1a和1b.1a和1b经稀酸水解，即脱保护而分别生成新的酚型开链冠醚2a和2b。

The two Fraunhofer lines at 688nm and 760nm are obvious in the radiance spectra by ASD FieldSpec Pro NIR spectrometer,which largely overlap the chlorophyll fluorescence emission spectrum of leaves.

第三，研究并分析了夫琅和费暗线方法计算的688nm和760nm波段的荧光特性，结果表明该方法计算的荧光是可靠的，它与光合有效辐射关系密切，复相关系数达到了0.9；冬小麦冠层荧光光谱在760nm和688nm波段的荧光大小基本相等，而地锦冠层荧光光谱在688nm波段的荧光强度是760nm的3倍左右，表明荧光光谱能够更加敏感地反映植被物种或生理生化状况的差别。

02"What if I want to send you a letter up there in New York?" says Wayne Belanger, a man with dirty silver hair and hands as thick as encyclopedias who mixes French into his English, calling storms "tempets" and me "tee frere."

伟恩问道﹐"如果要写信到纽约给你﹐要怎麼寄﹖"伟恩头发灰白﹐手臂粗厚像百科全书﹐说话英语夹杂着法语﹐暴风雨不说 storm ﹐而说 tempet ﹐他称我为'兄弟'，用的是 tee frere，兄弟用的是法文﹐冠词却是英文冠词的变体。

He distinguished, here and there in that swarming and formless mass, now near him, now afar off and on inaccessible table-lands, some group, some detail, vividly illuminated; here the galley-sergeant and his cudgel; there the gendarme and his sword; yonder the mitred archbishop; away at the top, like a sort of sun, the Emperor, crowned and dazzling.

这儿那儿，在那堆蠕蠕欲动、形状畸异、忽远忽近的东西上面和一些高不可攀的高原上面，他看见一群群的人，被强烈的光线照得须眉毕现，这儿是携带棍棒的狱卒，手持钢刀的警察，那边是戴着高冠的总主教，最高处，一片圆光的中央，却是戴着冠冕、耀人眼睛的帝王。

The crown of the wise is their riches: the folly of fools, imprudence.

智慧人的冠冕，是他们的机智；愚昧人的冠冕，是他们的糊涂。

We are really happy to know them. Beon English is not so good, can only use Simple English to communicate. Hope they could understand what he typed. Here is our friend cfp's blog: http://cutfingerproductions.blogspot.com/, cfp and us are belonged to handmade people, we love to create!!! When Laura wants us to make her a special key-ring, we come out with this idea,"Elephant" cause is cfp logo and Laura can handmade too!! So we hand stitched Laura's in chinese word, we think it's really suit her!!! Hope she will like it!!! Thanks Laura and Jon for being our friends!!

每次都是称赞鼓励的话虽然星仔的英文不是很好但是体贴的她们总是用简单的英语与我们沟通真的很高兴认识她们因为我们都是在网路上与大家分享自己手工的作品， http：//cutfingerproductions.blogspot.com/所以当Laura说想要冠头送她几个中文字时冠头就想到这几个字因为大象刚好是她们的Logo加上她的中文名子应该很贴切吧也希望她会喜欢这几个字虽然看不懂哈。。。。。。。。
