1、Finally, the atmosphere generates all types of weather such as clear blue skies and storms. It acts as a huge energy machine, changing sunlight into other forms of energy such as heat and wind. As part of this role, the atmosphere regulates the temperature on the Earths surface. First it allows only

2、 46 percent of the sunlight striking it to pass through and actually reach the Earths surface. Second, carbon dioxide gas in the atmosphere controls the amount of warmth on the Earths surface that is allowed to radiate （ 发散 ） back into space. By these two controlling devices, the atmosphere regulate

9、light into other forms of energy. the atmosphere3.Although_are mostly absorbed by the ozorie layer, doctors suggest that people should limit the amount of time spent in direct sunlight. high-energy ultraviolet light raysCompared with argon, neon and hydrogen,are more important in helping to make lif

10、e possible. oxygen, nitrogen, and carbon dioxide5. The purpose of wearing a suntan lotion is to protect people from sunburn and skin cancer翻译：地球的大气层除非下雨或风在吹，我们通常不会注重气氛，周围的空气，地球毯子。然而，如果没有大气层，地球将是一个荒凉（荒芜的）与没有生命迹象的星球！这里的气氛起着帮助，使生活成为可能多个角色。首先，提供了三种气体的大气生命所必需：氧，氮和二氧化碳。所有动物，包括我们自己，呼吸氧气。氮和二氧化碳都是植物生长所需。减重要的

11、大气气体包括氩，氖，氦和氢。其次，气氛也免受太阳的高能紫外线照射，这是我们一生中最有害的。虽然这些射线仅是地球的太阳光的显着一小部分，他们被称为是非常危险的。但是，所有99百分之的吸收紫外线，才到达地球表面。它们是由大气中吸收气体，称为臭氧的氧气气体种类。臭氧层环绕地球，但远在南极和北极薄于地球表面上的其他地区。对大气中的紫外线百分之一的不到达地球表面的已知会导致晒伤，现在相信很多人也会造成皮肤癌。正因为如此，医生建议人们限制了他们的时间花费在阳光直射和穿防晒油（防晒油），阻止了紫外线当他们这样做日光浴。最后，大气产生如湛蓝的天空，所有的风暴天气类型。它作为一个巨大的能源机器，改变成其他能源形

12、式，如热，风能阳光。作为该角色的一部分，大气调节地球表面的温度。首先，它仅允许46个惊人它通过和实际到达地球表面的太阳光百分之。其次，二氧化碳在大气中的二氧化碳气体控制着地球表面的温暖允许量的辐射（发散）回太空。这两个控制装置，大气调节地球表面的温度。选择最好的回答下列问题。1。下列哪个是真实根据这篇文章？答：臭氧层远远超过北美厚度超过了北极。二臭氧是一种类型的氮气。三臭氧能吸收紫外线，才一些到达地球表面。四臭氧能够保护任何有损于我们的生活我们。2。第三个段落的主要思想是的。地球周围是一对臭氧层二99所有的紫外线光线到达地球表面的百分之是臭氧层所吸收C中的臭氧层可保护来自太阳的高能紫外线照射的

13、人四臭氧是一种气体，大气环绕地球3。根据这篇文章，二氧化碳是一个不太重要的大气气体二控制的温暖对地球表面的数量C.能只有百分之46的阳光到达地球表面四就像一个巨大的能源机器4。医生建议。人们应该远离阳光客场自己免受晒伤乙人应该阻止紫外线当他们这样做日光浴三人应戴直射阳光下防晒霜四日光浴的人应该知道结果是皮肤癌5。地球将是一个荒凉的星球，因为没有大气层主要是由大气中的氧，氢和氮，这是我们生活不可缺少的B的气氛使生活中可能扮演多种角色C的气氛只允许无害射线到达地球D.在温暖的气氛中就控制了地球表面的数量完成与在文章中给出的信息下面的句子。比，超过有效期为地球其他地区的臭氧层在南北极。关键：更厚它is_that变成其他形式的能源的阳光。主要包括：大气 Although_are大多由ozorie层吸收，医生建议，人们应限制在阳光直射下花费的时间。高能紫外线照射氩，氖和氢比较，更重要的帮助，使生活成为可能。氧，氮和二氧化碳对佩戴一个防晒霜的目的是防止晒伤和皮肤癌的人
