自由命題,選擇愛護(hù)鳥類保護(hù)環(huán)境方面的編寫,要求注意條理清楚,語言生動(dòng),描寫細(xì)致,詳略得當(dāng),要在100字以上。

【答案】愛護(hù)鳥類保護(hù)環(huán)境

鳥,是人類的朋友;鳥,是大自然的音樂家;鳥,是自然之子。有了鳥兒,大自然更美了;沒有鳥兒,世界就沒有了生機(jī)。

鳥類的減少,使害蟲失去控制而大量繁殖,人們被迫求助于農(nóng)藥來消滅害蟲,這樣造成惡性循環(huán),鳥類因食物的減少而減少。 為恢復(fù)和改善自然環(huán)境,我們應(yīng)該植樹造林。

鳥類對(duì)污染反應(yīng)要比人類敏感,它的死亡與繁盛是反映環(huán)境污染程度的重要標(biāo)志。城市上空黑煙籠罩、空氣污濁,加上刺耳的噪聲,鳥類被迫遷往他鄉(xiāng)謀生。資料顯示,由于環(huán)境因素的改變,使世界上近百中鳥類已經(jīng)滅絕,還有近200種鳥類瀕臨滅絕的危險(xiǎn)?梢哉f,嚴(yán)重的空氣污染可造成鳥類毀滅的災(zāi)難。

我國(guó)是鳥類資源的世界五強(qiáng)之一。據(jù)統(tǒng)計(jì),現(xiàn)有鳥類1300多種,約占世界鳥類種類的13.5%,其中候鳥500多種;鳥類多樣性也極為豐富,許多珍貴鳥類為我國(guó)所特有,如珍稀鶴類8種,占60%;雉類50種,占27%;歌聲婉轉(zhuǎn)的畫眉類334種,占24%。每年境外還有許多種類的候鳥遷徙經(jīng)過我國(guó)境內(nèi)。保護(hù)好鳥類資源對(duì)維護(hù)生態(tài)平衡,保護(hù)生物多樣性具有十分重要的作用?墒,由于一些利欲熏心的獵鳥者盯上了它們,一些地方非法獵捕、殺害、收購(gòu)、運(yùn)輸、出售野生鳥類案件屢屢發(fā)生。再加上一些地區(qū)砍伐樹木,減少了鳥類的棲息場(chǎng)所。

為了共筑美好家園,請(qǐng)關(guān)愛鳥類,讓它們與我們的心一起飛翔!

春天來了

冬天過去了,微風(fēng)悄悄地送來了春天。

地里的泥土化凍了,變松了,踩上去軟綿綿的,像踩著厚厚的地毯。麥苗醒來了,舒展著嫩綠的葉子。

小河里,連一片薄(báo)冰也找不到了。水慢慢地流著。微風(fēng)吹來,水面泛(fàn)起魚鱗(lín)似的波紋,幾只鴨子跳進(jìn)水里,快活地游來游去。

河岸上,柳樹發(fā)芽了,柔軟的枝條隨著微風(fēng)輕輕地?cái)[動(dòng)。一只青蛙從洞里鉆出來,在河邊慢慢地爬著。

春天來了。它來到了教室里,靜靜地聽小學(xué)生讀書,唱歌。它來到了操場(chǎng)上,歡樂地和小學(xué)生做游戲。
