So he invented a very simple camera. He put it in a window of his house and took a picture of his garden. That was the first photo.The next important date in the history of photography was in 1837. That year, Daguere, another Frenchman, took a picture of his reading room. He used a new kind of camera in a different way. In his picture you could see everything very clearly, even the smallest thing. This kind of photo was called a Daguerrotype.Soon, other people began to use Daguerro’s way. Travelers brought back wonderful photos from all around the world. People took pictures of famous buildings, cities and mountains.In about 1840, photography was developed. Then photographers could take pictures of people and moving things. That was not simple. The photographers had to carry a lot of film and other machines. But this did not stop them. For example, some in the United States worked so hard.Mathew Brady was a famous American photographer. He took many pictures of great people. The pictures were unusual because they were very lifelike(栩栩如生的). Photographers also became one kind of art by the end of the 19th century. Some photos were not just copies of the real world.

关于月考的作文(15篇)
关于月考的作文（精选15篇）关于月考的作文（精选15篇）在平凡的学习、工作、生活中，大家总免不了要接触或使用吧，借助作文可以宣泄心中的情感，调节自己的心情。
那要怎么写好作文呢？以下是为大家的关于月考的作文（精选15篇），希望对大家有所帮助。
时间如流水般淌过，转眼间第一次月考席卷而来。
我满怀憧憬的走进考场，但结果让我大失所望。
面对这一张张优而不尖试卷，令我不禁陷入沉思；看着一道道不该错的题目被印上伤疤时，心底里感到无比地自责；望着这鲜红但低的分数，更是让我痛定思痛。
使我为今后的学习惴惴不安。
当我静下来，再仔细地浏览试卷时，才发现原己是多么地粗心、急躁。
最让我痛心的是数学，由于被前面耽误点时间，最后一简单的压轴题就被扒去了10分；最让我意外的是语文，一篇深浅适中的作文让我费力脑汁，整整夺走了我15分；最让我伤心的是科学，不知道是不是因为底子薄，科学生物就扣走了我20分；最让我失望的是英语，一篇普普通通的阅读理解就拿走了我8分，单词填空更是毫不客气，10分就这样从我手头上溜过。
我还一味的掩饰，在老师面前说时间不够；在同学面前佯装作我太不小心；在家长面前却说因为没有复习。
现在一回想起，才觉得自己是多么的可笑、多么的无知！这次月考如同一面闪亮的镜子，映照着我缺乏的地方。
从这次月考中我总结出许多学习道理和学习方法。
如果只一味地去找理由，或把错的责任推到别人身上，那么便会永远掩盖着错误，一直错下去；如果不吸取教训，或只弄得一知半懂的话，今后的学习更是难上加难。
知识是靠日积月累的，人不可能在极短的时间内，把大量的学习内容灌输入到大脑里去。
“饥一顿饱一顿”或“三天一打鱼两天一晒网”这样只会一事无成的。
因此，一定要做到定时定量学习。
学习语文或英语时，不要只顾着死记硬背，要用理解性的方法去学；学习数学或科学时，不能不懂不会就空着不做，这样只会形成恶性循环，使我的学习一落千丈；学习社会时更要注意，由于是开卷，不懂的千千万万不能空着。
