一枝红杏出墙来——浅谈新课标下信息技术与语文阅读教学的整合

蓦然回首，我们惊喜地看见信息技术已渗透到语文教与学的方方面面，并与之亲密接触，完美整合，语文教学告别了“粉笔加黑板、白纸加黑字”的黑白世界，渐入“声音、色彩、图片、动画、电影相融合”的佳境。信息技术犹如“一枝出墙红杏”，受到广大师生的关注和利用。     

五色梅

马鞭草科马缨丹属。产美洲热带，中国广东、海南、福建、台湾、广西等省区有栽培，且已逸为野生。为常绿半藤本灌木。喜光，喜温暖湿润气候。适应性强，耐干旱瘠薄，但不耐寒，在疏松肥沃排水良好的砂壤土中生长较好。花期6-10月。

难觅踪迹的白臀叶猴

白臀叶猴又叫黄面叶猴、海南叶猴、毛臀叶猴等。在分类学上隶属于猴科、白臀叶猴属，因为头骨的差异较大，所以与我国广西等地分布的黑叶猴、白头叶猴等不同属。它的雄兽体形略大于雌兽，体长大约为61～76厘米，尾长约为56-76厘米，体重7-10千克，是体色最绚丽多彩的灵长目动物之一。长长的尾巴为白色，尾巴外围呈三角形的臀盘也是白的，因此得名，雄兽的臀盘上端还有两个白色的圆点，但雌兽没有。     

阴山荠属的校订

The genus Yinshania was established by Ma Yu-chuan and Zhao Yi-zhi in 1979, when only one species, Y. albiflora Ma et Y. Z. Zhao, was discribed from Nei Monggol.  In the present paper the genus Yinshania is revised and four new species, two new varieties and four new combinetions are reported.  There are so far eight species and two varieties in total in this genus.      Important morphological characters of the genus are analysed, which shows that the lateral nectariferous glands positioned at lateral base of the brevistamens are triangularovoid; there are dense minute pustules on the surface of valves, which is easily neglected because the pustules disap- pear or shrinked when dry; simple or furcate hairs are present in the most species, seldom absent; the shape of pollen grains is relatively steady, elliptic or long-elliptic, with the polar view trifid- circular, the equatorial view elliptic or long elliptic, the aperture 3-colpate, exine reticular.      The type of genus Yinshania is changed.  Cochlearia acutangula O. E. Schulz was published in 1929, but Y. albiflora Ma et Y. Z. Zhao in 1979.  They are the same species and a new com- binetion, Y. acutangula (O. E. Schulz) Y. H. Zhang, is made. Thus, the type of genus Yin- shania should be changed to Y. acutangula (O. E. Schulz) Y. H. Zhang.      Besides, He Ye-qi 6121 (paratype, PE), which is different from Y. acutangula var. albif- lora, is separated from it and transferred the typical variety, Y. acutangula.      According to the characters of fruit shape the genus Yinshania is divided into two sections, namely, Sect.  Microcarpa and Sect. Yinshania, and then Sect. Yinshania is subdivided into two series.      Sect. 1. Microcarpa. Silicles widely ovoid or subglobose, 1-2.2 mm long, 0.8-2.2 mm wide, the ratio of length and width about 1.1.      Sect. 2. Yinshania. Silicles oblong, oblong-ovoid or long-lanceolate, ellipsoidal, 1.5-4.5 mm long, 0.3-1.5 mm wide, the ratio of length and width about 2.5-3.3.      Ser. 1. Henryanae. Raches flexuose; plants densely  hairy; leaves  3-5-foliolate,  seldom pinnatipartite or pinnatisect.      Ser. 2. Yinshania. Raches non flexuose; plants sparsely hairy; leaves pinnatisect or pinna- tipartite.      The genus Yinshania is a genus endemic to China, with their range from eastern Xizang to western Hubei from northern Guizhou to central Nei Monggol.  The taxa are mostly of a small area.  Sect. Microcarpa is concentrated in Sichuan and southern Gansu;  Sect.  Yinshania is spread from Xizang and Sichuan, nouthwards to Gansu, Ningxia, Shanxi, Hebei and Nei Mong- gol (Ser. Yinshania); and from Sichuan south-eastwards to Guizhou and Hebei (Ser. Henrya- nae).  There are five species in Sichuan.  The present paper conjectures that the distribution centre of the genus is in the Hengduan Mountains and its adjacent areas.     

中国珠蕨属的分类修订

对国产珠蕨属Cryptogramma R.Br.的分类进行了修订，承认2种1变种，即稀叶珠蕨C.stelleri（Gm l.）Prantl，高山珠蕨C.brunoniana Wall.ex Hook.&Grev.和珠蕨C.bru noniana var.sinensis（Christ）G.M.Zhang。将峨眉珠蕨C.emeiensis Ching&K.H.Shing并入高山珠蕨。同时对该属的系统位置进行了讨论。
