篇1:关于成长的优秀高中作文
全文共 771 字
+ 加入清单自从我迷上电脑游戏以来,妈妈的脸上就布满民乌云,那种神色至今想起来也让人有些心悸。
我竭力想脱离这个冷战的岁月,努力找个话题使妈妈开心起来,像以往一样谈话和调侃,但是这难以做到。由于前几次吵架的阴影,我们说着说着妈妈的脸就狰狞起来,强作镇定的说:“你能不能就别玩游戏!你看你现在,除了游戏别的都不重要啦!”
我此时只能以沉默应对。她不知已对我说了多少次这类的话。但我发现这次不同寻常,妈妈的眼里闪着点点泪花,那晶莹的泪光啊,忽然唤起了我蓝天下的回忆:碧蓝天空金色的阳光渗入云层,下面广袤的原野,上面布满了欢乐的人群,其中一个孩子拉着母亲的手,一起去放风筝。雪白的风筝啊,随风摇摆,在天空上留下灿烂的痕迹每次它被风快要吹走的时候,母亲的手就会伸过来,有力地将它拉回。
我也不知道是什么时候了,只知道那个时候没有烦恼、没有电脑,也没有束缚,只有无限地对蓝天的追求……
此时妈妈却站在我面前,要我做一个艰难的抉择。我没有像以往一样反驳她,跟她讲所谓的理论。阳光忽然亮了,明亮却不刺眼,一瞬间布满了妈妈深黑的瞳孔。我愧疚地低下了头,咬着牙多想象个孩子一样,告诉妈妈我错了。难道真的是因为我长大了,这些话无论如何也说不出去了么?那么能证明我的只有行动了。我做得到么?
次日清晨,妈妈出去跑步了。本来在这时我一定会偷偷儿玩会儿电脑,不顾风险,不顾承诺。但今天有点不同寻常。我只是看了一眼萎靡在书房的电脑,然后咬一咬牙,又轻吁一口浊气,坐在了阳台的沙发上。轻轻俯视着小区里那鸟语花香的一片景色,世界竟是那么灿烂而美好。我的心被深深地融化了……
我要坐在这里,等待朝阳升起,等待母亲回来。告诉她,请把电脑带走,请原谅你桀骜不驯的儿子;告诉她,做一个决定其实并不那么难,母爱就象阳光,当你接受产理解它的时候,什么都变得不那么重要了,你会释然一切,成长已不再拥有烦恼与忧伤。

篇3:关于代沟英语作文高中
全文共 999 字
+ 加入清单Generation gap refers to the misunderstanding between the old and young.
The term came into fashion after the 1980s. However, in recent years, the
phenomenon is getting more and more fierce.
How does generation gap come into being? The first reason is that the two
generations have grown up in different ages, thus they have different attitudes
toward life. Secondly, due to having little in common with each other, they are
unwilling to sit down and talk face to face. Besides, as modern life is so
stressful, both of them are so busy with their study or work that they have not
enough time to exchange their ideas.
To bridge the generation gap is not easy at all, but we can do something to
shorten it. For one thing, children should respect their parents as well as
accept their good advice. For another, parents should not only show their love
and care to the kids, but also support their good life view. As long as the old
and young can understand each other, it would be more harmonious in family and
world.
篇4:中考英语作文出色善用“潜规则”的方法
全文共 1032 字
+ 加入清单很多同学对英语书面表达的部分都感到头疼,一是因为突然拿到一个题目,脑中一片空白,写不出几个句子来,二是写好一篇文章,可是总是流于平淡,语言枯燥,不得老师喜爱,分数也一直不高不低,难以突破。建议同学们,第一类问题,是可以通过练习而补救的,第二类问题,则需要我们的积累和智慧了。
每一次考试或练习,我们的语文写作中总是时不时的会出现很多诗词,名言,他们或哲理,或抒情,或励志,或优美,总能让我们的文章读来津津有味,而且让老师觉得有文学感,甚至会因此而觉得有文采。同样是作文,我们为什么不能把这种思路搬到英文中来呢?答案当然是可以的,而且成功的例子也不少。
在英文的写作当中,运用名言警句这样的潜规则也是存在的。根据目前的要求,一篇英文作文篇幅在100词以上,这样的长度相对于语文作文来说自然是很简单了,但是对于高考水平的英语写作来说,是完全有空间在其中运用名言警句的,只要我们用的合适,就会取得意想不到的效果。
那么,我们如何善用这些名言警句呢?
第一,积累是必需的。英语是一门语言,语言是没有速成的,尤其是一些经典的词句,是需要我们一点一滴积累的。在收集名言警句的过程中,我们可以有目的性地收集。所谓目的性,是指在作文中,命题的形式和题材一般是固定的,那么针对这样的内容,我们就要尽量收集能用得上的名言警句,或者说,名言警句要对的上路子,这么做可能有一点功利,但咱们毕竟是应试,退一步说,这样收集的句子也不一定都是没有用的,所以,我们要首先找准方向,少走弯路。
第一类是哲理类的,这一类名言警句可以说是万精油,放之四海而皆准,几乎在每一篇作文中都能用到它们。比如说描写做家务活。我们就可以用上Just as the saying goes: It is never too late to learn!来说明学习做家务活的积极性。再比如以汶川地震为背景描写一个叫Lin Hao的小孩救出同学的事迹,我们就能用As we all know, where there is a life, there is a hope.或者where there is a will, there is a way来赞扬Lin Hao的精神品质等等,诸如此类的命题比比皆是,只要我们用得恰当,就一定能波的阅卷老师的青睐;
第二类是励志类的,这种语句在涉及到个人成长经历内容的文章中,可以发挥很大作用;
第三类是情感类的,表现家庭生活或者个人情感的内容能用到它。

I want to return their love, so I must become more independent and mature. So that my parents will be less worried about me and can go travel to enjoy their lives. For me, I want to cherish every moment, enjoy my own life and let the time go more slowly.
在中国的春节联欢晚会上,歌曲“时间都去哪儿了”很受欢迎。歌词很动人,以至于人们听到歌曲的时候,很多记忆都涌现出来。
对于我们父母那一代人来说,他们结婚,生孩子,然后看着孩子独立,时间过得真快啊。一切就如他们昨天成为父母,然后今天就成为了祖父母。
时间过的如此的快,他们都没有意识到自己老了。我很感激父母,因为他们为了做了那么多事情。
我想要回报他们的爱,所以我必须变得更加的独立和成熟。这样父母就不用为我操那么多的心,可以去旅游,享受生活。对于我来说,我想要珍惜每一刻,享受我的生活,让时间走得慢些。

全文共 1155 字
+ 加入清单Beautiful outlook indeed attracts people’s attention, if people have the beautiful outlook, of course they will give people deep impression, just like the saying that everyone has the mind of appreciating beauty.
But we must figure out the fact that outlook can’t decide everything, only the ability can do it.
The good example is Mariah Sharapova, she is a famous tennis player. Early in her career, people noticed her beautiful outlook, but more and more beautiful female tennis players come into being, only Mariah gets famous all the time, the reason is that she is outstanding amongst these girls.
She has won so many championships, which makes her the most attractive girl.
Beautiful outlook opens a door for people, but only the ability makes them standing all the time. People will get the genius respect for their hard working instead of their attractive faces.
美丽的外貌确实吸引人们的注意,如果人们拥有好看的外表,理所当然能给人留下深刻的印象,就如有句话说爱美之心,人皆有之。但是我们必须弄清楚外表并不能决定一切,只有能力才能决定一切。
玛利亚莎拉波娃就是最好的例子,她是一位出名的网球运动员。在她早期的职业生涯中,人们注意到了她的美丽外表,但是随后越来越多美丽的女子网球选手出现,而只有玛利亚一直有名气,原因在于她是这些女孩当中最出色的。
她赢得了很多的冠军,这让她最吸引人们的注意。
美丽的外表对于人们来说只是打开了一扇门,但是只有实力才能让她们一直出众。人们会因为他们的努力而得到尊重,不是因为他们吸引人的外貌。
篇10:2024考研英语高分作文写作方法
全文共 951 字
+ 加入清单对于作文这一部分来说,大家应该首先了解不同文章的特点和规律,下面是小编整理的2017考研英语高分作文写作方法,欢迎阅读。
一、了解意图,抓住精髓
近年来的大作文非常玄妙,值得细品。首先,很可能大作文正在经历由时事向哲理过渡的重大变革,这在2001年、2002年、2004年、2007年、2009和2010年真题上表现得最为明显。其次,出题人将尽量用图画来表达意图,而不借助或少借助图中或图旁的文字,这样意义表达的会更深刻,对考生的思考力和判断力的要求也就更高。第三,图画的含义深刻,可以接受的解释也较多,但要想取得高分,必须紧扣图画,把握住其中的精髓,最深刻地表达其核心的意义。
二、扣紧主题
写大作文时切记要扣紧主题,切不可离题太远,导致最后回不来或时间不够写不完。另外,各部分之间的比例应适当,第一段不要太长。与主题相关的关键词语一定要用对,否则会影响分数。
三、看清要求
有的同学一看到写“网络”,就立即联想到这方面最火爆的话题“网络成瘾”,将主题确定为此。有的同学干脆将之转变为自己看到过的文章——“网络的利与弊”。这些都是不正确的做法。写大作文时,首先要减少语言的错误,提高语言的准确性。语言错误有许多种,有的是小错误,甚至可以忽略不计,而有些是大错误,是让老师看到后不得不扣分的错误。另一方面就是增加闪光点,除了结构清晰外,闪光点主要指好的词、词组或句型,一是使用恰当,二是要有变换。上述这两点都不容易,而结合起来就更难了。如果文章分为三段,那么起始段、结尾段和中间段落的开始部分是非常关键的。对于背诵的好词、词组和句型,一定要和具体的行文联系起来,融入到文章中去,不仅要用对,还要用好,避免给人突兀的感觉。
四、避免投机取巧
近年来,有些考生有投机的心理,结果却很惨烈。有的考生准备了万能模板,直接往上套,这样的效果并不好。正如有的较为激进的阅卷老师所说,这些考生是想通过不诚实的手段得到不属于他的东西,这样的人应该得到惩罚。实际上这些考生中有的水平还不错,如果坚持依靠自己,咬紧牙关奋力拼搏的话,结果会是不错的。
综上所述,对于作文这一部分来说,大家应该首先了解不同文章的特点和规律,而后用心地学习范文并进行模仿,然后练习全文写作并请老师批改再细细揣摩。相信通过这样的过程,大家的写作一定会有长足的进步。
篇11:高中英语作文:接纳不完美的一面
全文共 1038 字
+ 加入清单When my friends ask me to take pictures of them, they will take a lot of pictures and then only keep a few of them.
Because they are not satisfied with most pictures, they think they are not perfect.
Actually, when I look at the pictures, there is nothing serious in my eyes, everyone in the pictures look as they are.
People chase for the perfect side, that’s why more and more people choose to have the plastic surgery.
Take the celebrities for example, they look beautiful enough, but to make themselves look perfect, most of them take the plastic surgery, which makes them look unnatural. People have to cost the great price for chasing the perfect side, while no one is perfect.
If we accept our imperfect side, we will live in the easy way and can enjoy the life.
当我的朋友们叫我帮拍照的时候,他们会拍很多照片,然而只有少部分照片能保存下来。因为他们不满意大部分的照片,觉得自己看起来不完美。实际上,当我看到照片的时候,在我看来没有什么大问题,照片中的每个人看起来都像他们自己的样子。人们追求完美的一面,这也是为什么越来越多的人选择去进行整容手术。就拿名人来说,他们看起来足够漂亮,但是为了让自己看起来完美,大部分人进行了整容手术,这让他们看起来不自然。为了追求完美,人们不得不付出很大的代价,然而没有人是完美的。如果我们接受自己不完美的方面,那么我们就会过得轻松点,享受好生活。
篇12:英语考试作文800字
全文共 1086 字
+ 加入清单当今天剑桥英语考试的铃声响起时,我感觉全身都已经不是自己的了,像是换了一个人的身体一样。我的手不停的颤抖着,笔尖也在颤抖,在桌子上不断地留下来回摩擦的声音。为什么我对英语考试这么害怕呢?因为我妈妈给我要求的是必须认真对待,争取考到100分。但是我对自己很没有“信心”,所以心里十分的担心。一直想着该怎么答题?要怎么才答得好,考到一。百分。就在这时考试的铃声响起了,我之前在脑袋里记到的知识,突然间一下子就飞走了。当我正在想怎么才能将那些知识找回来的时候?老师开始念听力了,我十分无奈的跟着老师的思路走,生怕有半点遗漏。
过了一会儿,老师终于把听力讲完了,我感觉浑身都松了一口气儿,但这还没完,老师紧接着说:“同学们,这次考试要认真对待,今天的题很难一定要认真考试哦。”老师不说这句话还好,但老师一说,我就感觉浑身都不自在了,感觉就像望子成龙的那些妈妈一直逼迫孩子学习,在我的心里,老师分明是在说一定要考好,不准考差。
我吓的浑身哆嗦,开始回忆我以前学过的知识,但是墙上那钟表的嘀嗒声一直在困扰着我,我想起了这个,又因为滴答声,忘了那个,一直这样重复了几次。我有点不耐烦了,我心想算了吧?直接做吧!至少比干坐在这里,思考我以前学过的知识要好吧!我拿起了笔开始面对试卷,但是看到第一道题我就傻眼了,这道题要用原形和Ing进行式加到语句上面,但是在这道题目上,老师根本就没讲这种情况,这可怎么办呢?我无可奈何,只好拿出我的点兵点将大法,但是可惜这是道填空题我没能用上我的点兵点将大法,这使我脑袋都大了一号,没办法,我只好垂头丧气地往后做,可是越往后做我的心情就越烦躁,心情也就越忐忑,有很多题,明明在上课的时候,我都听到过,但是我就是一时想不起来了。
我心想算了吧,随便猜个答案都填上去吧!我真要这么做的时候,我却看到桌子上,不知谁用钢笔在上面刻了一句话,人可以被毁灭,但不能被打败,这一句话,可能是谁在上课的时候无聊随便刻的,但是他却成为了我这次考试的救命稻草,我转念一想,是啊,我不能被打败,我必须冷静下来尽自己的最大努力做下去,就这样时间又嘀嗒嘀嗒的过去了。不一会儿时间就到了,我垂头丧气的准备走上去交上试卷,但是我又想起了刚才可在桌子上那句话,就算我做的不好,我也要做出,我好像做得很好的样子,于是我马上抬头挺胸,挺着腰板走了上去。放学时我看到老师改完试卷才走,唉,才考了96分。
后来我把这件事情告诉了妈妈,本以为妈妈会大吵我一顿,但是她却夸奖我在关键的时刻没有放弃这一项做的很好。暂时一两次考试不好没什么关系,但是必须要在你受挫折的时候,坚强起来!坚持起来!那才是你该做的!

篇15:保护海洋高中英语作文
全文共 2299 字
+ 加入清单Oceans becoming more acidicThe worlds oceans are slowly getting more acidic, say scientists.The researchers from California say the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters pH value is not great at the moment but could pose a serious threat to current marine life if it continues, they warn.Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.Increasing use of fossil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater.
Once in the water, it reacts to form carbonic acid.Scientists believe that the oceans have already become slightly more acidic over the last century.But these researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira."And we predicted amounts of future acidity that exceed anything we saw over the last several hundred million years, apart from perhaps after rare catastrophic events such as asteroid impacts."If carbon dioxide release continues unabated, ocean pH could be reduced by as much as 0.77 units, the authors warn.It is not absolutely clear what that means for marine life, however.
Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean lifeforms may be more sensitive to pH changes.Coral reefs and other organisms whose skeletons or shells contain calcium carbonate may be particularly affected, the team speculate. They could find it much more difficult to build these structures in water with a lower pH.In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming.But Dr Caldeira said that such a strategy should now be re-considered."Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing - because in releasing CO2 into the atmosphere we warm the planet; and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.
