Dear Petty,
I am happy to receive your letter and I am glad to hear that you have good days recently. I hope you can keep your happiness all the time. But I am not happy these days, because I feel great pressures. Two weeks ago, I caught a cold and then had a fever. I could do nothing in those days. Therefore, I asked for leave for four days to stay at home. I came back to school until the midterm examination.
I was not surprised that I did not do well in the exam. It makes me unhappy. I worked so hard to prepare for it. My parents comfort me that I would be better if I had not been ill. I hope I can recover soon. And I hope you can take good care of yourself.
sincerely yours.
时光隧道确实存有吗?大家又将会回到从前或超越将来吗?假如一个孩子跟我说这种,我一定夸她想像力非常好;可是霍金老先生对于此事作出的表述、思考、和想像却要我对于此事造成了疑惑和猜测穿越重生又将会完成吗?
在科技界,时空穿越一度被觉得是歪理邪说。以往由于担忧有些人会把怪人的标签贴纸在自身的身上,我对这个问题经常避而不见,但如今,我不再那麼小心谨慎了。我时间观念沉迷已久,如果有一台时间机器,我能去拜会意气风发的玛丽莲.梦露,或者拜访将望眼镜转为宇宙空间的伽利略,也许,我都会来到世界尽头,破译全部宇宙空间湮没谜团。史蒂芬霍金
这一段轻轻松松的文本源自霍金之口。这类话的确非常容易令人觉得他是个怪人。我觉得霍金用他的人的大脑思考着浩渺的宇宙空间,他善于思考,这表明他不仅是个怪人。
霍金向大家明确提出了第四维的定义。要是是努力学习的小孩都了解,大家身旁的实体线在一个三维的室内空间,而第四维也是一个如何的全球呢?它是一种关于时间的层面。第四维的安全通道也许能够 完成时空穿越,也称之为穿越重生。
霍金老先生明确提出了三种穿越重生方式。
1.虫洞。虫洞是啥?实际上虫洞就在大家身旁。这又不得不承认到比分子结构、分子也要小的间隙量子泡沫,虫洞就存有与量子泡沫当中,小到人眼没法看到。天地万物都存有虫洞,霍金觉得这一样适用時间,倘若大家能捕捉一个虫洞,将它变大到得以使人们乃至太空飞船从这当中越过。那麼,时空穿越就拥有期待。
2.黑洞:纯天然的时间机器。黑洞比全部太阳系也要重,正因它这般的重,或许将会让時间滞缓;可是难题就取决于,贴近超大型黑洞的`危险因素!
3.超快速。超越光速的速率或许能够 提升时间限制;可是这种猜测若得已完成,有或许会违背宇宙空间规律性。这就称之为谬论。
因此,回到从前的旅游应当不容易开演,最少如今沒有这类将会。可是,我却极其适用霍金的思考。他不但是个怪人,也是个奇人异事。他的信心,他的思考或许让将来的大家正惊讶着。历史时间一直超出人意想不到的。日常生活在远古时代的人们怎样想起大家如今的日常生活,就好似大家谁也不可以预测分析到长期的将来。因此,大家对将来填满想像。
很多情况下,大家对某件事拥有想像,却没法同霍金一样满怀明显的好奇心和坚定不移的恒心去研究不明,也许说大家对不明的害怕过深。
但我还是说起,坚持不懈自身的想像,没人能够 肯定地说你是错的,最少你比散仙多一颗想要探索的心。
也更是由于有许多像霍金一样勇于探索的生物学家,不,不应该只限于生物学家,应是全部敢于追寻为人们作出贡献的任何人,是她们促进历史的车轮滔滔前行。向他们致敬!
Every family has lots of housework. Everyone should learn to do some of it. I often help my parents do housework such as washing clothes, cleaning the room and watering flowers. I think I‘ve learned how to take good care of myself and my family by doing housework. Sometimes cleaning all the windows is an enjoyable experience. I really felt proud of myself. And doing housework is also a kind of exercise. The summer holiday is coming. I'm going to learn how to cook some dishes. My parents will be happy to enjoy them.
每个家庭都有很多的家务事,每个人都应该学会去做一些。我经常帮助我的父母做家务,如洗衣服,打扫房间和浇花。我想从做家务中我学会了如何照顾自己和我的家人。有的时候擦玻璃是一种享受,我为自己感到骄傲。做家务也是一种锻炼。暑假即将到来,我准备去学习一些料理,我的父母会很高兴的享用它们。
在这日新月异的时代,科技越来越发达,各种先进的设计层出不穷。其中最成功的发明当然非手机莫属了。我们几乎可以从每个角落看到手机的踪影,可见手机已经成了每个人日常生活的一份子。手机纵然给我们带来了许多的好处,不过它也带来了坏处,现在就让我们来谈谈吧!
有了手机,即使我们之间的距离再遥远,我们都可以和家人、朋友通话聊天。我们甚至可以下载一些免费的社交软件像是微信、微博、面子书等,让我们随时随地和别人聊天,认识新朋友。手机里的.一些应用程序也让我们的生活变得更加方便。给个例子,我们现在已经可以从网上购买日常用品,并在网上缴水电费,不用大老远地到别的地方付费。
此外,手机也为我们的生活增添了一份乐趣。无聊时,我们可以通过玩手机游戏来打发时间。另外,手机也可以让我们听听音乐,陶冶心情。手机也是我们学习的好帮手。在我们有问题时,我们只需搜索一些,便能找到答案了。
虽然手机带来的不少的好处,不过它带来的坏处也不少。像是有些学生因长时间玩手机游戏,而到了凌晨还没睡觉。隔天时,便感到十分疲累,在课堂上打瞌睡,从此成绩一落千丈。除此之外,有些学生也因使用手机观看一些黄色网站,让他们不知不觉中被这些文化影响。
手机带给我们最严重的坏处就是我们随处可见到的低头族。即使是大家聚在一起用餐时,我们还是看到所有人低着头在按手机。这样的现象让大家缺乏沟通,导致关系越来越疏远,也让我们的社交能力越来越差。
总而言之,手机是人类所发明的,所以我们应该要妥善地使用手机,而不是被手机控制了我们的生活。
Dear Yu:
Is it surprising that I write the letter for you ? Not one time had I wanted to express my heartfelt gratitude for you face to face . But I’m so shy that I can’t do that .Thus , I decide to say thank you in this way .
Meeting you is the most fortunate thing in the world . Your emergence brightens my life deeply . You know ,I used to be such a shy ,a quiet girl . I was afraid of contacting with others so that I merely had pretty few friends . All days I stayed at home , and my life was dull . It was not until you volunteered to assist me that my life set out changing . You took me to wander the streets to observe the world which greatly broadened my eyes . You encouraged me to take part in kinds of activities that promoted my courage and confidence . You were always enthusiastic to introducing me to your friends when I was fear of expressing myself in public . The wonderful characters you own deserve me to learning .Your optimism and vigour impress me so much .
Now , I have become confident and outgoing . I can firmly confront the difficulties ,never shrink . My dear friend ,thanks for leading me to a new world , thanks for letting me feel shiny warmth and never making me lonely . Comparing to what you have dong for me , simple thanks seem to be minor , but it’s my sincere appreciation and gratefulness .
Blessing you happy forever .
Yours Qing
