Unit 4 Astronomy：the science of the stars天文学：恒星科学晨读记忆 Explore MKII MKII, a planet billions of kilometers away, is the origin of life in many religions. Physicists have proved the theory that its gentle climate and the pull of its gravity are similar to the earths. And astronomers have found that oxygen atoms and carbon dioxide, which are fundamental to life, exist in its atmosphere through satellites. Cheered up by this news, biologists, in their turn, began to do some research to remove peoples puzzlesNow that there are some suitable conditions, does life really exist on this globe? Do they multiply by laying eggs or giving birth to babies? Last month, a spaceship was sent there. Its a pity that this mission failed. Unlike the earth, MKII is a much younger planet. Thus, masses of harmful acid clouds float everywhere causing violent chain reactions to break out. These clouds not only blocked out the pilots sight but also damaged the engine system. Luckily, the pilots watched out carefully and prevented the spaceship from crashing in time.探测MKII行星 MK二号是一颗几十亿公里外的行星，它在许多宗教里都是生命起源的地方。物理学家已经证明了它温和的气候和重力的牵引都和地球相似的理论;天文学家也通过卫星，在它的大气层里发现了氧原子和二氧化碳的存在，这些都是对生命来说，都是基本的。受到这一消息的鼓舞，生物学家们接着开始了研究以解开人们的迷惑既然有了适合的条件，生命真的存在于这个星球吗?他们是通过下蛋，还是产仔来繁殖后代的呢?上个月，一艘太空飞船被派到了那儿。可惜的是，这次任务失败了。不像地球，MK二号是一颗年轻得多的行星。因此，大团大团的有害酸云到处漂浮，引起猛烈的连锁反应的爆发。这些云团不仅阻挡了飞行员的视线，而且还损坏了发动机系统。幸运的是，飞行员小心注意，才及时阻止了飞船的坠毁。I.单词盘点1._(n.) 天文学2._(n.) 系统；体系；制度 3._(n.) 太阳系4._(n.) 宗教；宗教信仰 _(adj.) 宗教上的；虔诚的 5._(n.) 学说；理论 6._(n.) 原子7._(pron.&n.&adj.) 万亿； 十亿8._(n.) 球体；地球仪；地球_(adj.) 全球性的；全世界的 9._(adj.) 猛烈的；激烈的；强暴的_(adv.) 猛烈地；强烈地；凶猛地_(n.) 暴力；暴行10._(n.) 碳11._(prep.) 不同；不像 12. _(adj.) 基本的；基础的13._(adj.) 有害的_(n.&v.) 损害；伤害；危害_(adj.) 无害的14._(n.) 酸 15._(n.) 链子；连锁；锁链 16._(vt.&vi.)乘；增加17._(n.) 氧18._(vi.) 存在；生存 _(n.) 存在；生存19._(adv.) 因此；于是 20._(n.) 二氧化物21._(n.) 迷;难题 (vt.&vi) (使)迷惑;(使)为难 _(adj.) 感到迷惑的 _(adj.) 令人迷惑的22._(n.) 生物学 _(n.) 生物学家 23._(n.) 万有引力；重力24._(n.) 卫星；人造卫星 25._(adj.) 温和的；文雅的26._(n.) 物理学家_(n.) 物理学27._(n.) 气候28._(vt.&vi.) 碰撞；坠落 29._(n.) 宇宙飞船 30._(n.&v.) 拉(力)；拖；牵引力31._(vi.&vt.)

English or Chinglish？好性感Youre so hot ! Being from Canada I tend to prefer cooler weather.One particularly hot day I walked into the classroom and one student, seeing hot sweaty I was, commented.“Teacher, you look so hot. Some students understood the double meaning of hotand laughed. What she could have said was“You must be uncomfortable in this heat. 来自加拿大，所以我比较喜欢凉的天气。有一天非常热，当我走进教室一个学生看到我满身是汗就说：“Teacher, you look so hot.（老师，你看起来很性感）”一些学生知道“hot”有两个意思，因此都笑了。她应该说的是：“You must be uncomfortable in this heat.（这么热的天气你肯定很难受）”Tip: In English, the word hot of course means“热”.But in spoken English, hot also means very attractive or sexy（性感）”,so never say someone looks hot unless you really like them.与“长得好看”相关的词汇：babe n.靓女chic n.靓女hunk n.帅哥doll n.洋娃娃，玩偶voluptuous adj.艳丽的model material 模特胚子（特别适合当模特的人）head turner 漂亮的转头He/She is trouble 让人冲动的帅哥美女 摘自Kirk Kenny笑死我的英文书参考答案I.单词盘点1.astronomy 2.system 3.solar system 4.religion；religious 5.theory 6.atom 7.billion 8.globe；global 9.carbon 10.atmosphere 11.unlike 12.fundamental 13.harmful；harm；harmless 14.acid 15.chain 16.multiply 17.oxygen 18.exist；existence 19.thus 20.dioxid
