雪花

Every tree and every branch was encrusted with bright and delicate hoarfrost, white and pure as snow, delicate and defined as carved ivory.

每棵树，每一根树枝都包上一层明亮，精美的白霜，像雪花般洁白和纯净，如象牙雕一般精致优美。

The sgna gene, a synthetical agglutinin gene of Galanthus navies, codes a poisonous protein for Homoptera.

人工合成的雪花莲外源凝集素基因sgna可以编码对同翅目昆虫具有毒杀作用的蛋白。

However, few genes resistant to homoptera (sap-sucking) insects were isolated. Recent studies have shown that some plant lectins from Amaryllidaceae species are toxic to sap-sucking insects in artificial diet assay, among which the lectin from snowdrop is the most toxic and has been most widely used in plant insect-resistant breeding.

大量的研究结果表明，植物凝集素具有有效的抗虫作用，其中雪花莲外源凝集素(GNA，Galanthus nivalis agglutinin)已在植物基因工程中广泛应用，并对同翅目害虫如蚜虫和褐飞虱等表现出较好的抗性。

It was bitter winter weather, but I had been too full of passion to feel cold, and I walked through the quiet streets, with the snow drifting in my face, and a desperate hopefulness in my heart.

这是个严冬天气，但我已经满怀激情，一点也不觉得冷，我漫步穿过寂静的街道，雪花纷纷扬扬落在我脸上，我心里是孤注一掷的希望。

However, in these days of eco-awareness some people are rejecting hot-house flowers such as roses, for seasonal flowers native to Britain, for example snowdrops, which grow naturally in Britain in February.

现在人们有了环保意识，有的人不再接受温室里的花如红玫瑰，而代之以季节性的英格兰本土产的花，例如雪花莲，它就是自然生长在英格兰的二月份。

Sought for much after that, it will be found Either to have gone groping underground (And taken with it all the Hyla breed That shouted in the mist a month ago, Like ghost of sleigh bells in a ghost of snow)--Or flourished and come up in jewelweed, Weak foliage that is blown upon land bent Even against the way its waters wnt.

再过一阵子去看，便会发现溪水要嘛，全摸索到地底下去了(连带着所有的雨蛙族一个月前，它们还在迷雾之中叫着，像雪橇铃的鬼魂在雪花的鬼魂之中¨¨)要嘛，就挥舞着，在水金凤里冒了上来，细瘦的叶子在岸上被风吹斜而且还是背着流水的方向斜。

Make ice sand mainly, ice flower, ice surges ling, snow mud, snowflake junket, ice gruel.

主要制作冰砂；冰花；冰激凌；雪泥；雪蓉；雪花酪；冰粥。

The ambience of the city is ornate and frothy: white horses dancing to elegant music; snow dusting the opulent draperies of Empress Maria Theresa's monument; lavish decorations filling the interior courtyards of outwardly severe town houses; a gilded Johann Strauss among a grove of green trees; the voluptuous music of Richard Strauss; the geometric impasto of Klimt's paintings; the stately pavane of a mechanical clock.

维也纳的气氛是华丽和肤浅的：白马随着优雅的音乐翩翩起舞；雪花飘落在玛利亚。特里萨女皇纪念碑上华丽的装饰物上；外表朴素的住宅内，庭院却装饰奢华；在绿树从中有约翰。施特劳斯的镀金雕像；还有理查德。施特劳斯的悦耳音乐，克里木特的油画几何厚涂法和机械大钟奏响的庄严的孔雀舞曲。

"Your impatiens looks like floating snow," Evan said. It's a wonderful effect, having an all-white garden.

"你家的凤仙花看上去就像飘舞的雪花，"埃文说，"真是匠心独运，整个花园都是雪白的。"

He caught himself imagining the wonder of a caress from such a hand, and flushed guiltily. It was too gross a thought for her. In ways it seemed to impugn her high spirituality.

柔软，像雪花他没想到文人的手党能这么柔嫩可爱；他忽然发觉自己在想像着一个奇迹：接受一又像这样的手的抚摸，不禁羞惭得满脸通红。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
