剪紙是我國民間的一種傳統(tǒng)的裝飾藝術。和刺繡一樣，它是聰慧和技巧的結晶，又蘊涵著生活的美。其實，剪紙也并非一樁難事，只要經(jīng)常動手，堅持下來，就會功到自然成。那么畢竟該怎樣剪紙呢?

剪紙，選用工具是第一步。其次步是根據(jù)造型先進行紙張的折盈。例如，剪四方形的，對折再對折;五方形的，對折后，再按1：3的比例折成‘’V〞形。折一定要折得整齊、嚴實，并要壓平。初學者可先將花紋用淡筆畫上。第三步，根據(jù)畫出的筆印剪?；ㄕ袘嗖捎们鷹l紋，由于曲條紋往往耐看，富有滾動感。在剪的過程中，手對紙的轉動要和剪的方向協(xié)同好，膽大而心細，這樣剪出的紋路才明了連貫。最終，除去多余的部分，再剪出一個外框。這時，一件小小的作品即告完成。

剪出的作品可以珍藏在書中或空白筆記本中，夾在兩頁之間，上面再攫上一層半透明的紙，保持整齊。待心靜時翻閱欣賞，嘿，?那才是其樂無窮呢!

學習剪紙，可以培養(yǎng)自己多方面的品性：精細、專注、耐心、靈活等。在不斷實踐中，你會感受到剪紙藝術樂趣無窮。

傳聞水仙花是“凌波仙子〞的化身，其實它是多年生草本植物，屬于石蒜科，盛產(chǎn)于我國福建省的漳州地區(qū)，至今已有500多年歷史了，是中國傳統(tǒng)十大名花之一。水化花喜歡生活在潮濕的地方，多長在水中。假使它生活的地方溫度較高，就會吸收大量養(yǎng)料長出好多葉子，而開的花就少了。人們都希望水仙多開花，少長葉，花期長，那應當怎么辦呢?

雕刻好的水仙頭要放在水里浸泡一天左右。浸泡出根莖中的粘液后，用清水沖洗清白，再把刀削的傷口用清白的白色餐向紙(便于以后拿掉)輕輕地纏繞上，以利吸收水分，促進根的生長。洗凈、包好的水仙頭一般都擺放在紫砂水仙盆中。在盆底部碼上清白漂亮的小石子，用來穩(wěn)住水仙頭，再注入清水后，我們的工作就基本完成了。

最好的方法就是雕刻水仙。

拿到一個3年生水仙頭后，應率先判斷正反面。水仙頭露出的芽彎曲的一面是正面。雕刻水仙花頭正面的方法是：首先把水仙花外面的鱗片和枯燥的根削掉，其次把水仙花頭靠根部的1/3留下不動，一層一層地削掉上面2/3部分的鱗片，直到露出花芽為止，再在每片葉梢的邊緣削一下，以后花芽就會彎曲生長、能形成漂亮的造型。雕刻時請注意不要把花苞削破，以免影響花蕾的生長。

水仙花盆要放在陽光照射比較少的室內，室溫控制在8-10C左右，堅持每天換水。經(jīng)過5-6天，水仙花的苞蕾就會一個一個地長出來，葉子會浮現(xiàn)彎彎的形狀。這時，它生長很快，應當適時調整溫度，使它在將近春節(jié)時開出花來。假使溫度、濕度控制得好，花期一般在半個月左右。假使雕刻技藝精湛，便創(chuàng)作出一盆盆活靈活現(xiàn)的“天女散花〞、“花籃迎賓〞、“孔雀開屏〞、“天鵝展翅〞等盆景，使清香飄逸的水仙花更加多姿多彩，使人得到一種藝術享受。

新春佳節(jié)來臨，優(yōu)雅的水仙花佇立于一泓清水之上，亭亭玉立，競相開放，散發(fā)出淡淡清香，定會給您的新春佳節(jié)增加無限的情趣，給您的居室?guī)泶禾斓臍庀ⅰ?/p>

電是國家的商品是我們生活中必不可少的能源，沒有電，我們將無法生存，它的用途十分廣泛，如工廠，學校，醫(yī)院，餐飲，家居電給我們的生活的方方面面帶來了好多好處，但是假使不正確使用電會給我們帶來災難和不變，我從手機上看到一個新聞...

清早，我習慣性的拉開窗簾，一股寒氣迎面而來，馬路上的樹從頭到尾的變白了;田埂，草莖，屋脊都鋪上了白霜。我傻乎乎的跑到媽媽房間里興奮地說：媽媽，下雪了!媽媽迅速爬起來，向窗外張望，我在那
