动物世界 一匹来自北方的狼是什么狼 急

第二道防线由体液中的杀菌物质和吞噬细胞组成，杀菌物质中的溶菌酶能够破坏多种病菌的细胞壁，使病菌溶解死亡．受伤的哺乳动物经常用舌去舔伤口，这是因为口腔里的唾液含有溶菌酶，能破坏进入伤口处的病菌的细胞壁，进而杀灭病菌，这种免疫力是天生就具有的，对多种病原体都有作用，属于非特异性免疫．

My favorite TV program is "The animal's world".

我认为动物世界这个节目很棒.
I think “Animal World" is 【a】【great】【programme】.

很难, 这类很难写,如果你写好了,也许会红,但是还是属于比较冷门的题材,但写的人还是有的,以前遇到过几本这样的,好像都不怎么红.至少我就没兴趣,除非你的出发点是 反思人和动物的关系, 这类比较深奥的东西,但这样很很新颖,就更冷门了,像学术的东西.

I like Animal World.From watching it I knew how different animals lived,and I understood the relation between animals,nature and humans,and the importance of protecting animals.Animals are a big part in nature,it has nature along with humans,if humans want to live well,we'll need to maintain the balance of nature.Let us all love nature,and protect animals together!

墙角,什么东西白得发亮!
我不由自主低头看去,竟从墙洞里钻出一只成年白猫!
白猫仰着头,眨着一双滴溜溜大眼打量我,很细很小的轻唤声,眸子里满是希冀哀求.
风起了,瘦弱的小身子缩在墙边,一身白毛在风里乱飞.
“可怜,你饿了吧.”我蹲下来,掏出临走前美女姐姐塞给我的热烧卖,剥开层层包裹递到它面前,“快吃吧.”知道向人类乞求,多半是被人遗弃的猫.
白猫小心翼翼地嗅了嗅,没吃一口,反而转头向后喵呜喵呜的呼唤起来.
“怎么不吃?”我正诧异,就见墙洞里变戏法似的钻出一只幼年小猫,再一只、又一只,三只小花猫挨个钻了出来,全部挤到烧卖前埋头大吃.
而最早出现的那只成年白猫,则是站在一旁,守护般的静静等待.
我的心一震,这就是母亲吧

I think the animal world this great program

I like "the animal world" the column,not only because I thought the animal is humanity's friends,moreover because the director held spiritedly the program.had understood through the program many pasts did not know the thing.for example many moved the animal and their life situation,the person and animal's relations and the protection animal's significance.recently hears to some people to injure in the zoo the animal,asked whether could legislate severely punishes these injuries even to slaughter the animal the person.

Because I like wild animals,I like the Animal World programme on TV a lot.
