news presenter(newsreader, newscaster) anchorman or anchorwoman, news anchor or simply an anchor
A news presenter – also known as a newsreader, newscaster(short for "news broadcaster"), anchorman or anchorwoman, news anchor or simply an anchor – is a person who presents news during a news program on television, on the radio or on the Internet. They may also be a working journalist, assisting in the collection of news material and may, in addition, provide commentary during the program. News presenters most often work from a television studioor radio studio, but may also present the news from remote locations in the field related to a particular major news event.
新聞主播或新聞報導員通常指的是在電視台的新聞頻道、電台或網際網路等電子媒體上，
每節數分鐘、半小時以至一小時新聞報導的主持人，不同國家對主播的定義或身份階級有所分別。
Etymology of "anchor"[edit]
The terms anchor and anchorman are derived from the usage common in relay racing,[3] specifically the anchor leg,[4] where the position is typically given to the fastest or most experienced competitor on a team. In 1948, "anchor man" was used in the game show "Who Said That?" to refer to John Cameron Swayze, who was a permanent panel member of the show, in what may be the first usage of this term on television.[5] The anchor term then became commonly used by 1952 to describe the most prominent member of a panel of reporters or experts. The term "anchorman" also was used to describe Walter Cronkite's role at the Democratic and Republican National Conventions, where he coordinated switches between news points and reporters.[3]

聲納可能是鯨魚擱淺的元兇
聲納可能是鯨魚擱淺的元兇
根據最新的研究，軍艦與直升機發出的聲納（Sonar, Sound Navigation and Ranging 聲音導航與測距），迫使鯨魚潛入深海中過久，引發幾近水潛水夫病的致命症狀。
研究發現，一隻想逃離聲波的喙鯨，潛入海中的時間長達 163 分鐘，幾乎比全世界哺乳類最長的潛水紀錄還多出半個小時。
近年來，世界各地屢屢見到單一擱淺的鯨魚、整群擱淺的鯨魚。三禮拜前才有一隻領航鯨在蘇格蘭印威內斯（Inverness）擱淺。去年也發生數起長鬚鯨在英格蘭東部與南部海灘上擱淺的事件。
海洋生物學家把焦點放在聲納裝置對鯨魚擱淺的作用。聲納裝置廣播的音波，會比搖滾音樂更大聲，但略高於人類聽覺的範圍，以偵測海裡的潛水艇。許多擱淺的鯨魚被發現體內有許多氮氣泡，彷彿人類所得到的潛水夫病，也就是減壓症（decompression sickness）。
為了解釋這個現象，一群來自美國華盛頓州海洋生態與遙感探測研究所（Marine Ecology and Telemetry Research Centre）的科學家，在洛杉磯東南方 150 英哩處的太平洋，對十六頭柯氏喙鯨（Cuvier’s beaked whales）上了衛星標籤。
領銜的科學家是艾琳·費爾孔（Erin Falcone），她在 2014 年曾經發現柯氏喙鯨可以在深度兩英哩的海中沉潛兩小時十七分鐘。這一次，一隻上了標籤的鯨魚打破先前的紀錄 26 分鐘。
費爾孔發現，聲納的存在，導致鯨魚潛海的時間拉長，每次的間隔也拉長，使得一般一天潛海八次的鯨魚，會在聲納的影響下，減少為一天潛海三到四次。對於鯨魚活動影響更大的是直升機聲納，雖然它所發出的聲音較小，但它的發聲對鯨魚是無預警的。
費爾孔的研究報告已經在《開放科學》期刊（Royal Society Open Science）發表，她在報告主張，長時間在潛於深海，導致氮氣泡在鯨魚的脂肪與其他組織中累積，可能是導致牠們死亡的原因。
