端午的鸭蛋（节选）

家乡的端午，很多风俗和外地一样。系百索子。五色的丝线拧成小绳，系在手腕上。丝线是掉色的，洗脸时沾了水，手腕上就印得红一道绿一道的。做香角子。丝线缠成小粽子，里头装了香面，一个一个串起来，挂在帐钩上。贴五毒。红纸剪成五毒，贴在门坎上。贴符。这符是城隍庙送来的。城隍庙的老道士还是我的寄名干爹，他每年端午节前就派小道士送符来，还有两把小纸扇。符送来了，就贴在堂屋的门楣上。     

罗布泊的神秘老者

这个故事是酒桌上听来的。讲故事的人是一个姓赵老司机,他为南疆某地区的勘探队开了一辈子的车。50多岁就内退了。那件事发生在1992年。勘探队决定对罗布泊地区进行一次彻底的地质勘察。当时的罗布泊,已经彻底干涸,真正成为了寸草不生的不毛之地。勘探队派出了7名队员,两辆北京老吉普车。老赵就是其中一辆车的司机。

论蒙古包在生态学方面的意义

游牧民族，蒙古，藏，印第安，阿拉伯等游牧民族的可移动民居有共同点：木头支架，轻便，不用浆粘结，减轻自重，且摆脱了对水的依赖。容易装卸，驮运。唯有蒙古族发明使用蒙古包。蒙古包有它自己的特点。最明显的特点就是它的外形：包，包形。下部圆筒形，上部圆锥型，顶为拱形。我们现在知道，在材料相同的条件下，球形有最大的容积和最小的散热面积。其次是圆筒型。而锥形最稳定。     

高考英语答题中心理因素致误及防范

决定高考成败的因素主要有两个方面:一是掌握知识的多少,能力的高低;二是应试心理。本文主要对高考英语答题中心理因素致误情况做些分析,并谈谈如何防范。一是心理定势致误。心理定势,是指人的行为习惯、思维等方面的刻板状态。影响考试的心理定势有两方面。⑴习惯定势。有些同学平时就有违背常规做题的习惯,喜欢从最难的题目做起,认为“啃骨头”很有味道。这种方法用于平时时间充裕,容量不大的考试是可以的。但高考英语试卷容量大,时间很紧,如果也在难题上先花费过多的功夫,容易的题目反而来不及做。所以正确的方法应该是先易后难。⑵思维…     

帝国都市的地下动脉

说起英国伦敦,不可不提到它的地下交通。英国人称地铁为"管子",这一叫法倒也形象,因为行车的通道确实就像一根根管子,而且大多数车站的站台也呈管道形状。英国是世界上最先建设地铁的国家。1863年,它的第一条地铁在伦敦投入使用。当时的通车里程很短,不足10公里。由于使用的是蒸汽机车,隧道里烟雾弥漫。1890年,伦敦又建成了举世第一条电气化地铁。如今,伦敦的地铁系统已经相当复杂和庞大了。线路共有10多条,总     

黄鼠狼报复蛇

一个夏天的黄昏,一条三尺多长的灰蛇,无声无息地爬上镇头河边的一棵老柳树,盘踞在探向河面的一个旁枝上。它昂起三角形的头颅,目光像冰一样冷。老柳树的附近有一片荒草没膝的废墟。这片废墟的深处居住着一头年轻的黄鼠狼,灰蛇等待的正是这头黄鼠狼。蛇是不敢向黄鼠狼挑战的。黄鼠狼闪电般的敏捷使蛇难于招架。这条     

蒲公英

正蒲公英是一种野生植物,田野、路旁到处都有。春天的时候,蒲公英贴着地长起来。它的茎很短,叶子是绿色的,边缘像齿轮。过一段时间后,绿色的茎慢慢长高,长长。在茎的顶端开出一朵朵很不起眼的黄色小花。初夏到了,蒲公英的花朵开始凋谢了,花蒂处长出像冬天的滑雪帽上的绒球样的东西,有白色、粉色,真的很美。这时,如果有一阵风吹过,蒲公英的绒球就开始飘出一把把"小伞儿","小伞儿"下面是一个个黑色的种子,到处漫游。蒲公英随风而动,落地生根,随遇而安。

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Lower Paleozoic oil relationships within Williston Basin, Canada

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.     

An Analysis of Catherine＇s Character——Wuthering Heights

Wuthering Heights, Emily Bronte＇s only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

Characterization of Ordovician carbonate reservoirs, southeastern Saskatchewan, Canada

The discovery of the prolific Ordovician Red River reservoirs in 1995 in southeastern Saskatchewan was the catalyst for extensive exploration activity which resulted in the discovery of more than 15 new Red River pools. The best yields of Red River production to date have been from dolomite reservoirs. Understanding the processes of dolomitization is, therefore, crucial for the prediction of the connectivity, spatial distribution and heterogeneity of dolomite reservoirs.The Red River reservoirs in the Midale area consist of 3～4 thin dolomitized zones, with a total thickness of about 20 m, which occur at the top of the Yeoman Formation. Two types of replacement dolomite were recognized in the Red River reservoir: dolomitized burrow infills and dolomitized host matrix. The spatial distribution of dolomite suggests that burrowing organisms played an important role in facilitating the fluid flow in the backfilled sediments. This resulted in penecontemporaneous dolomitization of burrow infills by normal seawater. The dolomite in the host matrix is interpreted as having occurred at shallow burial by evaporitic seawater during precipitation of Lake Almar anhydrite that immediately overlies the Yeoman Formation. However, the low δ18O values of dolomited burrow infills (-5.9‰～ -7.8‰, PDB) and matrix dolomites (-6.6‰～ -8.1‰, avg. -7.4‰ PDB) compared to the estimated values for the late Ordovician marine dolomite could be attributed to modification and alteration of dolomite at higher temperatures during deeper burial, which could also be responsible for its 87Sr/86Sr ratios (0.7084～0.7088) that are higher than suggested for the late Ordovician seawaters (0.7078～0.7080). The trace amounts of saddle dolomite cement in the Red River carbonates are probably related to "cannibalization" of earlier replacement dolomite during the chemical compaction.

橡胶颗粒沥青混合料低温抗裂性试验研究

以AC-13级配为基础,将橡胶颗粒代替部分集料掺入混合料中,以低温弯曲试验为评价方法对不同橡胶颗粒掺量下沥青混合料的低温抗裂性进行研究,并引入应变能密度值对混合料的低温抗裂性进行综合评价.试验结果表明:橡胶颗粒沥青混合料试件的破坏微应变均超过2 300,满足冬寒区的技术指标;无论是否掺加橡胶颗粒,随着温度的下降,沥青混合料破坏时的最大弯拉强度增大,弯拉应变降低,劲度模量增大;弯曲应变能密度在胶粒掺量为1%左右时具有较大的弯曲应变能密度值,此时橡胶颗粒沥青混合料具有较好的低温抗裂性.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

Quantitative trait loci （QTLs） for quality traits related to protein and starch in wheat

Quality traits in wheat （Triticum aestirum L.） were studied by quantitative trait locus （QTL） analysis in a recombinant inbred line （RIL） population, a set of 131 lines derived from Chuan 35050 × Shannong 483 cross （ChSh）. Grains from RILs were assayed for 21 quality traits related to protein and starch. A total of 35 putative QTLs for 19 traits with a single QTL explaining 7.99-40.52% of phenotypic variations were detected on 10 chromosomes, 1D, 2A, 2D, 3B, 3D, 5A, 6A, 6B, 6D, and 7B. The additive effects of 30 QTLs were positive, contributed by Chuan 35050, the remaining 5 QTLs were negative with the additive effect contributed by Shannong 483. For protein traits, 15 QTLs were obtained and most of them were located on chromosomes 1 D, 3B and 6D, while 20 QTLs for starch traits were detected and most of them were located on chromosomes 3D, 6B and 7B. Only 7 QTLs for protein and starch traits were co-located in three regions on chromosomes 1D, 2A and 2D. These protein and starch trait QTLs showed a distinct distribution pattern in certain regions and chromosomes. Twenty-two QTLs were clustered in 6 regions of 5 chromosomes. Two QTL clusters for protein traits were located on chromosomes 1D and 3B, respectively, three clusters for starch traits on chromosomes 3D, 6B and 7B, and one cluster including protein and starch traits on chromosome 1D.     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.
