体育中考作文练习【二】
山本茂是日本警察科学研究所的一名法医，但他研究植物血型纯属偶然。一天，有个名叫大岛川冈的人驱车经过千叶县城郊时，不慎撞伤了一名儿童。几天之后，警察追踪到他的车。经检查，汽车的前轮上不仅粘有那名儿童的O型血，而且还带有B型、AB型两种血迹。于是，警局指控大岛川冈撞过三个人。但面对证据，大岛川冈只肯承认撞伤过一名儿童，对另两项指控坚决予以否认。另一方面，警方也不能提供确凿证据，法院一时难以裁决。
与此案相隔不久，一名妇女夜间死于床头。法医化验她的血迹为O型，而枕头上的血型却是AB型，于是被疑为他***。除此之外，并无凶手作案的任何证据。这时有人半开玩笑地说：“莫非枕头内的荞麦皮属AB型？”谁知这个谜一般的提示，给了一筹莫展中的山本茂一个极大的启迪。他决定取荞麦皮进行化验，最后发现荞麦皮果真属AB型，这使山本茂如获至宝，欣喜若狂。他立即对发岛川冈的汽车重新取样验证，结果发现车轮上的3种血型中，有两种属于植物。至此，撞人案才水落石出。
从那以后，山本茂一直潜心于植物血型的研究。据他对150种蔬菜、水果以及500种被子植物和裸子植物的种子的化验测定，证实了“植物也有血型”这一结论的普遍性。例如，桃叶等19种植物为A型血型；苹果、草莓、西瓜、海带等77种植物为O型血型；枝状水藻等54种植物为B型血型；李子、桃子等400种植物属于AB型血型。据目前的'研究可以肯定，植物血型与热泪血型是类同的。科学家还发现，同一种植物还可以有不同的血型，比如枫叶为黄色时，其血型为AB型，但秋天枫叶红了的时候，它的血型又变成了O型。
植物本无血液，何以有血型之分呢？根据现代分子生物学的基础理论可知，人类血型指的是血液中红血球细胞膜表面分子结构的类型。而植物体内相应存在一类带有糖基的蛋白质或多糖链，或称凝集素。有的植物的糖基恰好同人类体内的血型糖基相似；如果以人体抗血清进行鉴定血型的反应，植物体内的糖基也会跟人体抗血清发生反应，从而显示出植物糖基有相似于人的血型。为了弄清血型植物的基本作用，科学家对植物界作了深入研究后得出的结论是：如果植物糖基合成达到一定的长度，在它的尖端就会形成血型物质，然后合成就停止了。血型物质的黏性大，似乎还担负着保护植物体的作用。
科学家指出，植物血型是一门十分深奥的学问，其复杂程度绝不亚于动物血型，而且它很有可能成为人类社会的天然血库。换句话说，科学家研究植物血型的最终目标，就是要让植物为人类提供血源，使自然界繁茂的植物成为浩瀚的天然血库。
