英语海报是指用英语写的用于戏剧、电影等演出活动的招帖。
海报这一名称，最早起源于上海，是一种常见的宣传方式。旧时，海报是用于戏剧、电影等演出或球赛等活动的招帖。上海的人通常把职业性的戏剧演出称为“海”，而把从事职业性戏剧的表演称为“下海”。
作为剧目演出信息的具有宣传性的招徕顾客性的张贴物，也许是因为这个，人们便把它叫做“海报”。正规的海报中通常包括活动的性质、主办单位、时间、地点等内容，多用于影视剧和新品宣传中，利用图片、文字、色彩、空间等要素进行完整的结合，以恰当的形式向人们展示出宣传信息。
海报具备特点
(一)广告宣传性
海报希望社会各界的参与，它是广告的一种。有的海报加以美术的设计，以吸引更多的人加入活动。海报可以在媒体上刊登、播放，但大部分是张贴于人们易于见到的地方。其广告性色彩极其浓厚。
(二)商业性
海报是为某项活动作的前期广告和宣传，其目的是让人们参与其中，演出类海报占海报中的大部分，而演出类广告又往往着眼于商业性目的。当然，学术报告类的海报一般是不具有商业性的。

一篇关于日本核电站辐射问题的报道：Scientists lack complete answers on radiation riskShareretweetEmailPrint AP – Mother and daughter receive radiation exposure scanning in Fukushima, northern Japan Friday, March 18, … By The Associated Press The Associated Press – Fri Mar 18, 6:21 pm ETThyroid cancer for sure. Leukemia, probably. Too much radiation can raise the risk of developing cancer years down the road, scientists agree, and the young are most vulnerable. But just how much or how long an exposure is risky is not clear.Those are among the unknowns scientists are contemplating as the crisis unfolds at Japan's stricken nuclear power plant.In Japan, the Science Ministry said radiation levels about 19 miles northwest of the Fukushima Dai-ichi plant rose at one point Friday to 0.15 millisieverts per hour, about the amount absorbed in a chest X-ray. But levels have been fluctuating, and radiation at most sites that distance from the facility have been far below that.Long term, it is clear radiation can induce cancer. But researchers can't just count cancer cases after a disaster and declare radiation responsible. Rates before and after must be compared to know if more cases occurred than would be expected.That is why, 25 years after the Chernobyl accident, there is still controversy over its effects beyond the undisputed 6,000 cases of thyroid cancer. Of these cases, only 15 had proved fatal as of 2005, even though the Soviets were slow to treat victims of the catastrophe.The records necessary to spot trends in other types of cancer as a result of Chernobyl are poor, said Dr. Fred Mettler, a University of New Mexico scientist who led a United Nations-sponsored team investigating Chernobyl's health effects."At the end of the day, the scientific data isn't there. My instinct is, there probably is an increase there, but it's too small to see," he said.The U.S. Environmental Protection Agency says that no amount of radiation is absolutely safe above the 3 to 6 millisieverts a year that most of us get from normal living. In contrast, the Nuclear Regulatory Commission says that low doses — less than 100 millisieverts spread out over years — are not harmful. Researchers have not documented danger from such low levels, said Kelly Classic, a radiation physicist at the Mayo Clinic and a spokeswoman for the Health Physics Society, an organization of radiation safety specialists.High doses — over 500 millisieverts — can raise the risk of leukemia, breast, bladder, col
