“如果把一只蟑螂，等比例放大一百倍，会出现什么样的情况？”
”If a cockroach is enlarged one hundred times in the same proportion, what will happen?”
讲台上，头发稀疏的老师目光炯炯地望着教室，想看看底下学生们的发言。
On the podium, the thin-haired teacher looked at the classroom with piercing eyes, wanting to see what the students underneath were saying.
“它会偷吃鸡！”几乎在教授刚说完，教室角落里就传来这样一道声音。
“It will steal chicken!” Almost as soon as the professor finished speaking, such a voice came from the corner of the classroom.
“哈哈哈……”
“Hahaha…”
顿时引起了班上学生们的哄堂大笑。
suddenly caused a roar of laughter among the students in the class.
面容和善的老师听了之后，也没有生气，跟着笑了一会，点头道：“这是把你的想法代入蟑螂了，可以，谁还有什么其他想法？”
The kind-faced teacher didn’t get angry after listening to it. He laughed for a while, nodded and said: “This is the cockroach you thought, okay, who has any other ideas?”
“蟑螂变大一百倍，都有几米高了吧，我觉得，一只鸡它肯定不够吃！”
“The cockroach has become a hundred times bigger, and it is a few meters tall. I think, a chicken is definitely not enough to eat!”
学生们再次大笑了起来。
The students laughed again.
老师点了点头，笑道：“不错，继续！”
Teacher nodded and smiled: “Yes, continue!”
“蟑螂的体型变大，那它承受的重力也会变大，我觉得，它可能会被重力压死！”
“When the cockroach becomes larger, the gravity it bears will also increase. I think it might be crushed to death by gravity!”
“那可不一定，它可是等比例变大的，骨架肯定能撑得住重力的！”
“That’s not necessarily true, but it becomes larger in proportion, and the skeleton can definitely support gravity!”
“……”
”……”
老师看着底下一众积极发言的学生倍感欣慰，开口道：“生物学中有一个概念，叫‘异速增长关系’，是指生物的行为、形态以及所需能量等生物特征与体型之间存在着一种定量关系，也就是说，生物会随着生物体型变化而发生定量的变化，但是，这个变化并不是等比例的！”
Teacher was very pleased to see the students who were actively speaking, and said: “There is a concept in biology called’allometric growth relationship’, which refers to biological characteristics such as biological behavior, form, and energy required. There is a quantitative relationship with body shape, that is to say, living things will change quantitatively with the change of biological body shape, but this change is not proportional!”
他一边讲着，一边用粉笔在黑板上开始写起了公式。
While he was talking, he started to write the formula with chalk on the blackboard.
“这个概念最早由朱利安·赫胥黎于1932年提出的，这里，可以用一个数学公式来表示：E=70M^3/4”
”This concept was first proposed by Julian Huxley in 1932. Here, it can be expressed by a mathematical formula: E=70M^3/4″
“生物的形态、体型是呈线性增长的，这个关系是由平方-立方定律决定的。”
”The shape and size of organisms grow linearly. This relationship is determined by the square-cube law.”
“即，当一个生物体的长度翻到两倍时，那么它的表面积将是原来的四倍，而他的体积和质量则是原来的八倍……”
”That is, when the length of an organism is doubled, its surface area will be four times the original, and its volume and mass will be eight times the original…”
杜刚听到这里就走神了，确切的说，是把精神放到了脑海中突然出现的一个虚拟面板上。
Du Gang was distracted when he heard this. To be precise, he put his spirit on a virtual panel that suddenly appeared in his mind.
【杜刚】
【Du Gang】
【一阶古神】
【First-Order Ancient God】
古神，一种可以无限生长变大的物种！
Ancient God, a species that can grow and grow indefinitely!
理论上，只要能量足够，可以摘星吞月，成长到堪比星球大小……
Theoretically, as long as the energy is sufficient, you can pick up the stars and swallow the moon, and grow to the size of a planet…
在这段说明之下，是一个属性面板。
Below this description is a property panel.
第一行的位置，名叫一阶古神之基，已经被顺利点亮，在其后方括号中，还有一串暗淡的备注：（升级所需源能一万点。）
The position on the first line of , called the foundation of the first-order ancient god, has been smoothly lit. In the square brackets behind it, there is a series of dim remarks: (The upgrade requires 10,000 points.)
“古神之基？”
”The foundation of the ancient gods?”
几乎在杜刚思索到这里时，一段信息流直接涌现出来。
Almost when Du Gang thought about it here, a stream of information emerged directly.
“古神生长之基础，一阶上限为高度十米，可无视变身之后人体系统所带来的负面影响，当前每天可用时间：十分钟。”
”The foundation of the growth of the ancient gods, the upper limit of the first step is ten meters in height, which can ignore the negative impact of the human system after the transformation. The current available time per day: ten minutes.”
属性面板更像是一颗技能树，最上方的是古神之基，而在他的下方，第二行的位置，一共有八个分支。
The attribute panel is more like a skill tree. The top one is the foundation of the ancient gods, and below him, there are eight branches in the second row.
神经系统、运动系统、循环系统、呼吸系统、消化系统、内分泌系统、泌尿系统、生殖系统。
Nervous system, motor system, circulatory system, respiratory system, digestive system, endocrine system, urinary system, reproductive system.
此刻，这第二行的八大分支，全都是一片黯淡的模样，杜刚明白，这是没有被点亮的原因。
At this moment, the eight branches of the second line are all in a bleak appearance. Du Gang understood that this was the reason why they were not illuminated.
而在每个分支的后方，都有着一段备注：（激活所需源能一百点。）
And behind each branch, there is a note: (Activation requires 100 points of source energy.)
同时，他心中隐隐之间有一种感觉，只要自己想，现在就能变身成为一个‘巨人’。
At the same time, there is a faint feeling in his heart that as long as he wants to, he can transform into a ‘giant’ now.
但是，他按耐住了这种冲动，没敢在教室里尝试，而是睁开了眼睛。
However, he resisted this impulse and didn’t dare to try it in the classroom, instead he opened his eyes.
此时，生物老师依旧在讲课。
At this time, the biology teacher is still teaching.
“假如这只蟑螂的体重只有一克，体积是1×1×1＝1cm—3的话，那么在其每平方厘米的横截面上，只需要承受1克的重量。”
“If this cockroach weighs only one gram and its volume is 1×1×1=1cm—3, then it only needs to bear 1 gram of weight per square centimeter of its cross section.”
“将它放大一百倍后，体积就变成了100×100×100＝1000000cm3，若密度没有发生变化，那么它的体重则增加为1000000克，尽管它的横截面积也相应增大了，但也仅仅增加到了10000cm2，这说明什么？说明每平方厘米的横截面上所需要的承受的重量，增加了一百倍！”
” After magnifying it a hundred times, the volume becomes 100×100×100=1000000cm3. If the density does not change, then its weight will increase to 1000000 grams, although its cross-sectional area also increases accordingly. It’s bigger, but it’s only increased to 10000cm2. What does this mean? It means that the weight per square centimeter of the cross section has increased by a hundred times!”
“所以，如果这只蟑螂扩大了一百倍的话，它很快就会被自己的体重压死！”
”So, if this cockroach enlarges a hundred times, it will soon be crushed to death by its own weight!”
听到这里，杜刚皱起了眉头，举手提问道：“老师，那他要怎么样才能在体型变大后活下来呢？”
Hearing this, Du Gang frowned and raised his hand to ask: “Teacher, how can he survive when he grows larger?”
老师笑了笑，在黑板上写下了四个字：运动系统。
Teacher smiled and wrote four words on the blackboard: motor system.
“我说的它会被自己的体重压死，仅仅是运动系统对它的影响，除此之外，还要加上其他系统对它的影响……”
”I said that it will be crushed by its own weight. It is only the influence of the exercise system on it. In addition, the influence of other systems on it…”
“根据平方-立方定律，蟑螂在变大的同时，所需要的的氧气也大幅增长，交换气体部位表面积的增长，是无法跟上体积增长的……”
”According to the square-cube law, as cockroaches grow larger, the oxygen they need also greatly increases. The increase in the surface area of the gas exchange part cannot keep up with the increase in volume…”
“所以，在地球，如果有一只蟑螂体型变大了一百倍，那么他除了会被压死外，还会缺氧而死……”
”So, if a cockroach grows a hundred times bigger on the earth, in addition to being crushed to death, he will die due to lack of oxygen…”
紧接着，老师又写下了“呼吸系统”四个字。
Immediately afterwards, the teacher wrote the words “respiratory system”.
杜刚愣住了，下意识地喃喃道：“那缺氧问题有办法解决吗？”
Du Gang was taken aback, and subconsciously muttered: “Is there a way to solve the hypoxia problem?”
老师发现他入迷的模样，很是欣慰~IndoMTL.com~点头道：“也不是不可以，如果这个蟑螂增加更多气管，扩大吸收氧气的量，就能存活……”
Ms. found him fascinated, very pleased~IndoMTL.com~ nodded and said: “It’s not impossible. If this cockroach adds more trachea and expands the amount of oxygen absorbed, it can survive…”
“另外，如果地球空气中蕴含的氧气含量上升，也能够为它提供更多的活力……”
“In addition, if the oxygen content in the earth’s air increases, it can also provide it with more vitality…”
“科学家研究发现，在恐龙时代，生物都非常巨大，这其中的一个原因，可能就是大气中氧气含量非常高……”
“Scientists have discovered that in the age of dinosaurs, creatures were very huge. One of the reasons for this may be that the oxygen content in the atmosphere is very high…”
这时，有其他学生发问道：“老师，如果我们现在的氧气含量变高，那我是不是还能再长高？”
At this time, other students asked: “Teacher, if our oxygen content becomes higher, can I grow taller?”
老师眯起了眼睛，笑容满面道：“如果不考虑氧中毒的问题，而你恰好还在发育阶段，氧气含量增加，那么你确实是有可能在这种环境的影响下长高的……”
Teacher narrowed his eyes and said with a smile on his face: “If you don’t consider the problem of oxygen poisoning, and you happen to be in the developmental stage and the oxygen content is increasing, then it is indeed possible for you to grow taller under the influence of this environment. ……”
“在这种环境下，相比于动物，植物会成长的更快、更大、更高！”
”In this environment, plants will grow faster, bigger, and taller than animals!”
“当然，在这种富氧环境下，我们的下一代也会更高更大的！”
”Of course, in this oxygen-rich environment, our next generation will be taller and bigger!”
说到这里，老师将手一摊，笑道：“同学们，今天的课就上到这里，下节课，我们讲生殖系统和泌尿系统……”
Speaking of this, the teacher spread his hands and smiled and said: “Students, today’s class will end here, next class, we will talk about the reproductive system and urinary system…”
“生殖系统……嘿嘿嘿……”台下的学生们，都面红耳赤的偷笑了起来。
“The reproductive system…hehehe…” The students in the audience all snickered with blushing ears.
“在这里，我再说一个问题，什么是生殖细胞？”
”Here, let me say another question, what are germ cells?”
“请同学们回去以后，查阅一下课本，了解生殖细胞，我会在下节课，再提一个有意思的问题让大家来回答……”
”After students go back, please check the textbook and understand the germ cells. I will ask another interesting question for everyone to answer in the next class…”
“好了，下课！”
“Alright, get out of class is over!”
学生们顿时站了起来，鞠躬道：“老师再见！”
The students stood up and bowed: “Goodbye teacher!”
老师点了点头，转身离开了教室。
Teacher nodded, turned and left the classroom.
就在老师离开的教室没过多久，突然有学生大喊道：“快看手机头条！”
Not long after the teacher left the classroom, suddenly a student yelled: “Look at the headlines on the phone!”
