从第一个海藻类动物出现，地球上的生物已经在这个蓝色的星球上演化了几十亿年。在这个我们赖以生存的地球上，牢刻着多少动物的脚印？大自然的鬼斧神工曾经打造过多少生灵？他们在这个窄小的“栖息地”里竞争、生存、繁延、生息，他们在这样一个弱肉强食的世界里，我们的祖先以聪明的头脑生存了下来。
经过几千年的演变和进化，我们拥有了极高的科技水平，但是，某些观点是没有科学依据的。比如蚊子，它是人人都讨厌的东西，还有一些人甚至认为：如果没有蚊子了，我们的'生活将会变得更好！但是，你曾想过，蚊子和我们的生活息息相关。
假如自然界没圾蚊子，将会发生怎样的情况呢？蜻蜓的幼虫在水里生长，是靠吃蚊子的幼虫生存的。假如没有蚊子蜻蜓的幼虫就会饿，久而久之，蜻蜓就会灭绝。一些靠蜻蜓生存的生物也难逃灭绝的命运。以此类推，将会牵连一大片，许多生物就会因此灭绝。就好比一串鞭炮，只要点燃其中一个，其它的也会被点燃。假如世界上没有蚊子，人类的生活不会变得更好，反而更坏。
我们人类亲手缔造了一个高度的文明，但有得必有失。随着人类工业化的发展，一条条清澈的小溪变成了臭水沟；一片片碧绿的森林变成了一个个荒凉的沙漠。从十八世纪起，人类的活动严重破坏发大自然生态环境。人类排放的污水源源不断的流向大海，1/4的海水被污染过；排放的废气升上了天空，产生了温室效应，使两极冰层融化，使海平面上升，沿海房屋被淹没，一些生活在两极的动物无家可归。人类还大量捕捉鱼、鲸、老虎、狮子……使很多物种绝迹,严重破坏了生物链、食物链。不仅如此，人类还无休止的砍伐树木，现在我们尝到了应有的痛苦了，自然灾害频繁爆发。比如黄河边经常决堤，闹得两岸百姓叫苦不迭；北京经常刮起沙暴，这是大自然的怒吼，是对我们敲响的警钟！

“我不喜欢弟弟或妹妹，因为那样爸爸妈妈就不会再爱我……”最近上网总能看到类似于二胎这样的话题。这个政策是去年新颁布的，瞬间引起了社会各界的更关注，它已成为我们备考高考作文的话题之一。
此政策在网络和微信上引发了热议(become a sensation on the Internet and We Chat。不少网友认为"00后"(children born after 2000太自私，即使是同意父母生二胎的`孩子，在有了弟弟妹妹后脾气也会变坏。但也有不少人认为，这仅仅是教育方式的问题而已(the problem lies in education。如青岛一所小学的一群四年级学生日前成立了"反弟弟妹妹联盟"，说服父母不要生二胎。(A group of fourth-graders at an elementary school in Qingdao formed an "anti-siblings alliance" in an effort to persuade their parents not to have a second child.该校一名老师最近发现，班里有八个孩子常聚在一起窃窃私语，讨论这件事(hold secret meetings to discuss the issue。这些学生担心弟弟妹妹会分走自己独享的父母宠爱(steal their parents' exclusive love。
有话题就会有相关词汇，这就要求大家在平常的学习中多多积累，这样到用了时候心中自然就有丘壑。同时也可以扩充相关词汇，如：流动人口mobile population;独生子女家庭only child family;生育时间表birth time schedule;备孕plan for pregnancy。
二胎政策实施过程中，也给社会带来了一定的影响。这一部分探讨也可以作为作文的写作素材。如全面二孩政策(universal two-child policy出台后，中国内地主要城市三居室或四居室的大户型房子(large three or four-bedroom homes销量攀升。北京和上海等城市的很多夫妇正在搜寻居住环境更佳的大房子(hunt for larger homes with a better environment，为家里添丁加口早做准备。据估计，新的生育政策将使未来5年内多增加1700万新生儿(extra 17m babies being born within the next five years。

看了周月泉的漫画，展现在我的.眼前是一位偷伐者正得意地笑着，他为自己偷伐树木的成功而兴奋，为自己又可以赚一大笔钱而得意，嘴角微微翘起，嘴里叼着雪茄，脸上泛着阵阵红晕，斧头在手中有力地挥舞着，树被他砍得发出了阵阵呻吟声，而他并没有手下留情，依然我行我素，脑海中时不时浮现着自己赚大钱的样子。正当他美美地想着，突然飞来了一只啄木鸟来啄他的头，并
气愤地说道：“这里面一定有虫。”
看了这幅漫画，我不禁为之动容。是啊！在这位偷伐者的脑袋中的确有这样一只虫。那是一只自私、贪婪之虫，这位偷伐者只顾自己眼前的利益，而不做长远打算。生活中，像偷伐者这样贪得无厌的人比比皆是。有一些人为了自己能赚到钱而去打猎，把一只只可爱的动物伤害了。试问这些人的良知在哪里？他们有没有想过将来，有没有想过自己的子子孙孙呀！他们好比一只井底蛙，目光短暂。同时他们是自私的，有些人甚至建起了工厂，大量排放污水，是小鱼不能回到自己那清澈可爱的家园，这些是多么可恨啊！
人类啊，因为你们的自私、贪婪，使原本清澈的小溪，现在已污浊难闻；原本碧緑的草地，现在已成高楼大厦；原本动听的鸟鸣声，现在已寂静无聊。人类啊，不要等到地球上的最后一滴水是你们的眼泪时，才开始后悔，人类啊！醒醒吧！不要在为了眼前的蝇头小利而破坏大自然了。请让生命之水长流，请让生命之緑永驻，请让和谐之树常青，请让文明之花永不凋谢！请让我们携起手来，共同缔造美好緑色的明天吧！

Emerging from the cartoon is an eye-catching scene that the parents are willing to have a second child, while their only child do not agree because of his worry that he doesn't want to have another child, even his own sibling, share toys with him. Simple as it is, the symbolic meaning revealed is profound and thought-provoking.
We are supposed to place our attention on, instead of its funny appearance, the implied meaning of the cartoon: as the overall second-child policy expands throughout China, some only children are so selfish that they cannot accept the second child in their family. What can account for this undesirable situation? For one thing, they, as the only child at home all the time, have no awareness of sharing what they like with others due to the fact that all the family members give their love to the only child. As a result, when faced with the problem of whether they are willing to have a sibling, their first response is to refuse it. For another reason, some couples are eager to have a second child as soon as possible, which makes them neglect to communicate with their only child to let them realize the advantage of having a sibling companion in their childhood.
From what has been discussed above, it's safe for me to conclude that it is urgent to take some immediate and effective measures. What I recommend is that parents should let child know the importance of sharing with others, which is beneficial for them in future life. In addition, it's better for parents to have more communication with their only child once they want to have a second child.

China is a great country with the largest population in the world. In order to solve the population problem, our government decides to implemented one-child policy. When it is carried out for some time, many people not only see its advantages but also disadvantages. Thus, people argue that two-child policy should be put into effect. In my opinion, two-child policy should be carried out.
中国是一个人口大国。为了解决人口问题，我国政府决定实施独生子女政策。执行一段时间后，许多人不仅看到了这个政策的优点还有缺点。因此，人们开始推崇二胎政策。在我看来，二胎政策是应该实施的。作文
First of all, two-child policy is the gift for some only child. For some families, maybe the parents are only child and they also can have only child. Put aside the loneliness of their child, when their child grows up and they grow older, their child marry with an only child girl accidentally, the burden on their child and his wife is unimaginable heavy. Their child and his wife have to take care of two old couples. Usually, a young couple looking after an old couple is a little difficult; if the pressure increasing twice, how can they stand it. But if their parents have two children, they can share the burden of taking care of their parents. It would be much better.
首先，二胎政策对于一些独生子女来说是天赐的礼物。对于一些家庭来说，也许父母都是独生子女，而他们也只生一个孩子。抛开孩子的孤独不说，当他们的孩子长大了，而他们也变老了，他们的孩子又和一个独生子女结婚，这样的话,压在他们孩子和孩子妻子肩上的压力是不可想象的。他们的孩子和他的妻子不得不照顾两对老人。通常，一对年轻的夫妇照顾一对老人就有点难了;如果压力增加了一倍，他们怎么能忍受呢。但是如果他们的父母有两个孩子，他们就能分享照顾父母的压力。这样会比较好。
Secondly, two-child policy can guarantee the number of Chinese population. As the widely spread of one-child policy, some people have changed their conception about giving birth. If they firmly believe one-child policy, there will be more and more the dink. After several decades, our country will famous for lack of population.
其次，二胎政策可以确保中国的人口数量。由于广泛宣传独生子女政策，有些人已经改变了他们的生育观念。如果他们认同独生子女政策，就会有越老越多的丁克族。几十年后，我国就会以人口短缺而著名了。
In conclusion, one-child policy has out of date. And tow-child policy is needed and necessary. It can solve the problem of nowadays and the future.
总之，独生子女政策已经过时了。二胎政策是必要和必须的。这可以解决当前和未来的问题。
