海平面上升的危害英语作文【一】
第一，位图处理优势突出。图片存储形式整体上可划分为位图和矢量图两类，矢量图是计算机软件生成的特殊图像格式，它所占空间小、清晰度高、不失真，但由于图像每一种元素都独立成为“个体”，因此不存在过渡色，在视觉效果上远不如位图。相对而言，位图是基于图像色彩组合而形成的图片格式，因此它的图像丰富但文件较大，分辨率调整过高会导致失真。Photoshop是针对位图处理设计的一款软件产品，在进行平面设计的过程中，可以有效地实现位图元素的分割、组合，满足不同色彩之间的过渡需求，从而产生更加绚丽多彩的视觉效果。第二，符合工业印刷标准。计算机硬件设计中智能识别RGB颜色，这与标准印刷工业的需要存在较大差异，Photoshop引入了数字图形编辑和创作的工业化标准，通过融合CMYK功能来配合印刷产业，这极大地释放了Photoshop在平面设计的生产力。第三，分层选区特色工具。平面设计绝大多数情况下是进行“图片处理”，现代社会可直接获取数字化图片的途径很多，如智能手机、数码相机等设备，原始图片以位图形式存储，可导入Photoshop软件进行必要的修饰，以提升整个图片的美感。图片修饰基于添加、删减和变化三个途径，在分层机制下利用选取工具可以实现快速抠图、拼接、局部修改等操作，同时配合各种滤镜功能，如曲线调整（明度、亮度、饱和度）、滤镜工具等，可以实现更加完美的视觉效果。
海平面上升的危害英语作文【二】
Recently, the topic of air pollution has again aroused more and more attention since pollution haze, a kind of weather, has appeared increasing frequently in our cities. Just as the picture showed, when pollution haze comes, the whole city was covered with suspended particles which can breath into our body causing heavy problem to our health.
Due to the bad effect from pollution haze, a green and clear environment, rather than anything else, turns to be an important role and a urgent issue in our daily lives. Meanwhile we just live in only an earth, if we didn’t try to protect our common hometown, we would have no place to settle.
Thus, we should take effective measures to rebuild our beautiful environment of the cities from now on.
In my opinion, law and regulations should be enforced by the government and authorities to control the emission of polluting gas. To ourselves, we should enhance the awareness of environment protection and choose a green lifestyle to make contribution to our earth day from day
海平面上升的危害英语作文【三】
星期天，我在爸爸的帮助下，上网查了一下西安三月份前半个月的空气质量，一查，让我大吃一惊，我发现其中国重度污染有六天，轻度污染有两天，中度污染有七天。
原来我们生活在这样的环境下，我问爸爸：“雾霾和沙尘对人体有什么危害吗?”爸爸和我查阅了一下网上的资料，原来，雾霾和沙尘的危害非常大，雾霾会导致传染病扩散和多种疾病发生，给人体健康带来较大的危害。沙尘也会危害到人们的身体健康，还给人类出行带来很大的不便。
我又查了一下造成雾霾和沙尘的原因，原来大气空气气压低，空气不流动是主要因素，空气不流动是空气中的微小颗粒聚集在一起，漂浮在空中，由于地面灰尘大，空气温度低，地面的人和车辆是灰尘搅动起来……沙尘是一种风雨沙的相互作用的危害性天气现象，它的形成与地球温室效应、植被破坏、物种灭绝、气候异常等有着不可分割的关系。他还分为沙尘暴、浮尘、强沙尘……
我想我们不应该无节制开采自然资源，不应该随意砍伐树木，有车的人尽量少开车，多做公交车和骑自行车，绿色出行。灯泡尽量用节能灯，少开空调，大家要给街道多洒水。不随地乱扔垃圾，多植树造林，保护我们的地球。
