It's not just the trees that are thinking about the winter already. One of the local Hong Konger friend leased a car in March and managed to get by without fitting the proper winter tyres. Of course there were only a few days in March when the weather or road conditions became too tricky for normal tyres, but there'll be a lot more those days to come next winter. Who can blame him if he's started to look for winter tyres. A few of us told him not to worry so much for now since it's spring time, but the threat of winter seems to have started preoccupying his mind.

树木都暂时不想冬天，人就不然了，我其中有个香港朋友，三月租车时发现他的车原来没安装冬季轮胎，幸好那时只有三数天的天气和道路情况实在不宜用普通轮胎，但这些日子，下个冬季可能每天都是，所以他已开始着手找冬季轮胎了，我们都说，现在才是春天，不用这麼早便想这个问题吧，不过大家都心知，冬天其实离现在也不是太远了。

You see, it is with the winter winds gently dance, a shake a shake, a-down, which dance bleak winter color, but lacks some passion; it is head down to the earth gently tell, tell forward to winter, the feeling tone in the more helpless do anything for him; it is enjoying a winter rain baptism, baptism, it seems to be more of the fresh and natural, but less in spring and autumn the youthful vigor; it's head still wore winter rain left collections of diamonds, diamond it has become beautiful, but also adds a number of Qichu look.

你看，它正随冬风轻轻的舞蹈，一摇一摇，一上一下，它舞出了冬季凄凉的颜色，但缺少了一些热情；它正低着头向大地轻轻的诉说，诉说着对冬季的感受，语调中多了一丝的无奈；它正享受着冬雨的洗礼，洗礼后的它看上去更加的清新自然，但少了春秋季节的青春活力；它的头上还顶着冬雨留下的颗颗钻石，钻石让它变得美丽动人，但也增添了一些凄楚的神情。

Taking a winter wheat field (4 400 m2) of Jinghai county seed farm as experimental plot,sampling by regular grid with with 10 m ×10 m grids,48 sample points were oriented by GPS receipt machine to analyze soil water content at the depth of 0~20 and 20~40 cm in pri-winter,jointing stage and filling stage of winter wheat.The spatial distribution map of soil water of the winter wheat field using geostatistical analyst model of ARC/INFO was drew.And the spatial variability of soil water in vertical and horizontal direction was analyzed.The results could offer scientific evidence for the deciding of the exact time and quantity for winter irrigation.
