《侏罗纪公园》中，霸王龙被描述成侏罗纪最凶猛的食肉动物，它生活在1.6亿年前的侏罗纪。下列关于其体内的化学元素与人体内的

一般科学界命名一种生物用的是双名法,即属名+种名.暴龙是种名——Tyrannosaurus,而该属只有一个种,即Tyrannosaurus rex——霸王龙.同理：豹属 Panthera的下边有三个种,虎 P.tigris；狮 P.leo；豹 P.pardus（模式种）.所以在属下只有一个种的情况下,属名暴龙基本可以等于种名霸王龙,但有多各种时就不行了.基本称呼恐龙都叫它的属名,很少叫它的种名.
暴龙属只出现在晚白垩世的北美.
再往上是暴龙科,分为阿尔伯塔龙亚科（包含阿尔伯塔龙和蛇发女怪龙两属）和暴龙亚科,暴龙亚科广泛分布于晚白垩世的亚洲和北美,包含著名的惧龙、暴龙、特暴龙,可能还有山东的诸城暴龙.
再往上是暴龙超科,其中的祖母暴龙就出现于侏罗纪晚期的欧洲,但个体较小.
在我国新疆五彩湾发现的冠龙（种名五彩冠龙）属于原角鼻龙科,是暴龙类的祖先类型.冠龙生存于1亿6000万年前侏罗纪晚期牛津阶.
侏罗纪的顶层消费者比较多,欧洲应该是葡萄牙出土的蛮龙,北美是蛮龙、食蜥王龙以及差一些的异特龙.
咱们国家侏罗纪最大的可能就是中华盗龙和永川龙了.巨型永川龙比较大,有10米多长.
电影毕竟是电影,别当真.
推荐看一些比较好的纪录片：《与恐龙同行》、《恐龙星球》、还用最新的《恐龙革命/恐龙王朝》.

解题思路：生命和非生命的无机环境既有统一性又有差异性．
统一性：生命元素无机自然界都可以找到．
差异性：生命元素与无机自然界含量相差很大．
微量元素：Zn、Mo、Cu、B、Fe、Mn（油菜缺少B时只开花不结果）
主要元素：C、H、O、N、P、S
含量最高的四种元素：C、H、O、N
基本元素：C（干重下含量最高）

A、关于其体内的化学元素与人体内的化学元素，既有统一性又有差异性，统一性是指元素的种类相同，差异性是指元素含量不同，A错误；
B、种类相似即是元素的统一性，统一性是指元素的种类相同，B正确；
C、统一性是指元素的种类相同，C正确；
D、差异性是指元素含量不同，D正确．
故选：A．

点评：
本题考点： 糖类的组成元素．

考点点评： 本题主要考查学生对细胞中的元素种类和性质等考点的理解．

DNA是有半衰期的,这个值是521年,
有研究认为只需680万年DNA就会完全分解,
因此《侏罗纪公园》是完全没希望真实出现的.

Michael Crichton,in his novel,tells us how it is possible for us to have dinosaurs walking along side us in today's time.Steven Spielberg ambitiously takes it on himself to showcase the idea of dinosaurs walking and running along with us.And my God,what a wonderful job he does!Jurassic Park is simply an amazing movie that makes us drop our jaws and look in amazement and bewilderment at the dinosaurs as they walk on the silver screen.No encyclopedia and no book can be as effective as this movie is when it comes to showing what dinosaurs were and how grand they were when they ruled the earth.
The photography in the movie is outstanding.There is a scene at the beginning of the movie where we get to see the helicopter land on the heliport near a waterfall.The very beauty of the nature puts a smile on your face.And to make this shot even more wonderful,there is a wonderful music score that further broadens the smile.It puts you in a different mood altogether.And it does not fail to reproduce the magic even when you are seeing it again and again.Till today,whenever I see this one scene,it still puts a smile on my face.
Finally,when you get to that part of the movie where the dinosaurs are seen for the first time,your jaws drop.You look at them in sheer amazement.You are almost convinced that somehow dinosaurs continue to exist and all the filmmakers did was to capture them on their cameras!No,not true.Dinosaurs do not exist and the ones we see in this movie are computer animations.Any man who does not have any idea about how effective computer animation can be,they are surely going to believe that these mammoth creatures exist.There is much realism in them.
Prior to Jurassic Park,you always have had movies which were based on the concept of man vs beast.Once the movie has revealed the dinosaurs to us,the movie essentially becomes a struggle of survival.The dinosaurs are no longer secured and humans are in danger.I did not have any problem in this typicality of the plot.Because,it is not always necessary to create new plots.You can try and improvise on existing ones and show them in a more creative and different way.The Jurassic Park does that.So,I would not call it a weakness in the movie since it handles the overall plot beautifully.
If there is one complaint I would have for the movie,it is with regard to the villainous computer nerd who tries to sell off the embryos for cold cash.This part of the movie is a little loose and could have been handled in a better way.Also,the man who gets locked up in the toilet and the hunter getting outsmarted by the dinosaur are some things in the movie that are lame especially in comparison to how the overall plot has been so beautifully handled.But I still cannot take anything away from the movie.Sometimes negatives can be ignored if the positives are overwhelmingly strong.And the positives of the movie are way too strong for these things to be taken too seriously.
The movie is meant to be exciting and exciting it no doubt is.Steven Spielberg does a wonderful job with the Jurassic Park and this movie is surely destined to be a significant part of cinema history.It will be remembered for its special effects which were so excellently done.Though produced in early 90s,this movie can still be used as a benchmark to evaluate the standing of even the newer movies.
