?The United States Coast Guard now says it has discovered a debris field near the search area for a missing submersible near Titanic's wreckage. Thanks for joining us. I'm Paula Eben. The Coast Guard says teams are examining that field right now to see if it is actually connected to Titan, which was the submersible vessel carrying those five crewmembers. In other news, Nick Giovanni shows us how some newly arrived technology is helping out in the search effort. In a race against time, an active search for the missing submersible Titan continued Thursday morning with a pair of ROVs, a remotely operated underwater vehicle, deployed from French and Canadian vessels bound for the seafloor. It sends out a ping of sound that bounces off all the things around it and it comes back. So you can kind of see the shapes of things. The ROV was picked up by sonar buoys over the last two days, thought to be periodic, possibly rhythmic banging sounds. While estimates suggested the Titan, with five people on board, was set to run out of oxygen this morning. This estimate of 96 hours is coming from an assumption of an average consumption rate. There's not very many things average about being stuck in a submarine. The search area on the surface doubled in size yesterday to roughly 20,000 square miles. It's like being in the dark in a blizzard with a flashlight. And you're trying to find your keys in the snow. This is the scale of the challenge that you're looking at right now. Katie Croft Bell is the president and founder of the Ocean Discovery League, who's been working with ROVs for more than 20 years. She says navigating the seafloor is a slow operation. The hope is the submersible shape helps it stand out to searchers. That has, I think, probably sort of unique shape compared to a lot of the other debris and natural geological features in that area. So, hopefully they're able to get close enough to it that they'll be able to find it quickly. This is a very slow walk around the seafloor. This is not a blistering pace. So, that's the difficulty of it.

Section 1: Important Words

1. Debris field - a large area where pieces of wreckage are scattered around

Example: The rescuers found a debris field near the Titanic wreck.

2. Submersible - a small underwater vehicle designed for exploration or research

Example: The crew of five was traveling in a submersible when it went missing.

3. Vessel - a boat or ship that is used for transportation

Example: The French and Canadian vessels deployed ROVs to search for the missing submersible.

4. Ping - a pulse of sound sent out by a device to detect and locate underwater objects

Example: The ROV sends out a ping to locate the missing submersible.

5. Oxygen - a gas that is essential for breathing

Example: The missing crew might run out of oxygen if they are not found soon.

6. Consumption rate - the amount of a substance used up over time

Example: The 96-hour estimate to run out of oxygen is based on an average consumption rate.

7. Submarine - a type of vessel that operates underwater

Example: Being stuck in a submarine is far from an average experience.

8. Search area - the place where a search for something or someone is conducted

Example: The search area doubled in size to cover roughly 20,000 square miles.

9. Navigation - the process of directing a ship or boat

Example: Navigating the seafloor is a slow and challenging operation.

10. Geological features - natural and physical characteristics of the Earth's surface

Example: Finding the submersible's unique shape amidst other debris and geological features is the challenge for searchers.

Section 2: Important Grammars

1. Present tense - The article is written largely in present tense. It is used to describe ongoing events and actions in the present time. Example: The crew is still actively searching for the missing submersible.

2. Passive voice - The passive voice is used in the article to describe the action of the ROV sending a ping to locate the submersible. Example: It sends out a ping of sound that bounces off all the things around it and comes back.

3. Modal verbs - Modals such as "would" and "might" are used to express possibility and uncertainty. Example: The crew might run out of oxygen if they are not found soon.

美國(guó)海岸警衛(wèi)隊(duì)現(xiàn)在稱，在“泰坦尼克”號(hào)殘骸附近的搜索區(qū)域，他們發(fā)現(xiàn)了一片碎片場(chǎng)。感謝您加入我們。我是 Paula Eben。海岸警衛(wèi)隊(duì)說，團(tuán)隊(duì)正在檢查這片區(qū)域，以查看它是否與載有五名機(jī)組人員的泰坦有關(guān)。在其他消息中，Nick Giovanni向我們展示了一些新到達(dá)的技術(shù)，以幫助搜尋工作。在與時(shí)間賽跑的情況下，一對(duì)ROVs，即遠(yuǎn)程操作的水下車輛，繼續(xù)在周四早上展開對(duì)失蹤的泰坦的搜尋，這些車輛從法國(guó)和加拿大的船只上部署，前往海底。它發(fā)出聲音的信號(hào)，反彈到它周圍所有的東西，然后回來。因此，您可以看到物體的形狀。 ROV在過去兩天被聲納浮標(biāo)捕捉到，聲音被認(rèn)為是周期性的，可能是有規(guī)律的敲擊聲。盡管估計(jì)泰坦上有五個(gè)人，今早將耗盡氧氣。這一估計(jì)來自平均消耗率的假設(shè)。被困在潛艇里的經(jīng)歷是很少有什么平均的。昨天，表面搜索區(qū)域擴(kuò)大到大約20,000平方英里。它就像在暴風(fēng)雪中帶著手電筒在黑暗中尋找雪地里的鑰匙。這正是您現(xiàn)在面臨的挑戰(zhàn)規(guī)模。Katie Croft Bell是海洋發(fā)現(xiàn)聯(lián)賽的總裁兼創(chuàng)始人，她已經(jīng)使用ROVs工作了超過20年。她說，在海底航行是一個(gè)緩慢的過程。希望那個(gè)潛艇的形狀能夠幫助它在搜尋者中脫穎而出。與其他垃圾和自然地理特征相比，我認(rèn)為它具有獨(dú)特的形狀。所以，希望他們能夠靠近它，他們會(huì)很快找到它。這是在海底緩慢地走路。這不是閃電般的速度。這就是困難所在。
