I'm Carl Azuz, away from the CNN Center, but happy to be anchoring your news this Wednesday.

我是 Carl Azuz，不在 CNN 中心，但還是很開心這週三能為您播報。

The United States passed a milestone yesterday in the number of its Coronavirus cases.

在確診案例數方面，美國在昨天來到了一個驚人的數字。

According to John Hopkins University, more than one million cases of the disease have been confirmed in America.

據 John Hopkins 大學所說，美國的確診數已超過一百萬。

That's about a third of the cases confirmed worldwide, and when we produced this show, about 58,000 Americans had died from COVID-19.

這個數字大約佔了全球確診的三分之一，而當我們在製作這個節目時，已經有約 58,000 名的美國人死於 COVID-19。

For Perspective, the flu infects roughly 26 million Americans, on average each year, and it kills an average of 36,000 people.

流感一年平均感染 2,600 萬名美國人，殺死大概 3.6 萬人。

So based on those numbers, the flu infects many more people than Coronavirus has.

以數字來看，感染流感的人比感染新冠肺炎的人多上許多。

But COVID-19 is more dangerous.

但 COVID-19 要危險多了。

Some U.S. states are grappling with decisions on when to allow their businesses to reopen, and some have already started doing that.

某些州正在努力討論何時要讓企業再次開業，而有些州則是已經開放。

Antibody testing factors in here.

這是抗體試劑。

This can be done through blood samples, and it can detect if people have had Coronavirus, even if they don't know it.

這個可以用血液樣本來測試，它可以測試人們是否曾感染新冠肺炎，即使本人並不知道。

It's possible that those who've had the disease and then recovered from it, can be protected from getting infected again by the antibodies they develop.

有可能已經痊癒的人，可以靠抗體來預防自己再次感染。

But health officials say there's no proof that will happen.

但衛生官員表示目前還沒有證據。

They don't know how long it will last if it does, and there are concerns about the dependability of the antibody tests themselves.

就算真的有抗體，也不清楚抗體會存在多久，且他們對於抗體試劑的可信度還有一些疑慮。

But they're a step toward knowing who's had COVID-19 and possibly preventing the future spread of it, and contact tracing can help with that, too.

但他們正在努力找尋那些曾感染新冠肺炎的人，來進一步預防更多感染，而接觸追蹤可以幫忙找人。

Contact tracing is part detective work, part widely used public health method, and experts believe, a key strategy in fighting the Coronavirus pandemic.

接觸追蹤是偵查作業、廣泛被使用的公衛方法，且專家相信，這也是打擊疫情的關鍵策略。

It relies on identifying and interviewing every person who tests positive, isolating them, and then finding anyone else that person could have infected.

接觸追蹤就是追蹤並訪問所有確診者，隔離他們，並找出他們接觸過的所有人。

These people may then be quarantined before they can spread the infection to others.

然後再進一步隔離接觸過感染者的人，來預防散播。

A recent study estimates that because one person infected with COVID-19 can infect two to three other people, just one positive case can turn into more than 59,000 cases after ten rounds of infection

近期一份研究估算，一名 COVID-19 確診者可能會傳染給二至三人，因此只要有一個人確診，在經過十輪的傳染後，就會有 5.9 萬人感染。

Contact tracing can help prevent this potential wave of infections from becoming a tsunami.

接觸追蹤可以幫助預防這種如海嘯般的傳染。

It's a tedious approach, but one that is widely credited with stopping SARS in 2004, after that outbreak infected more than 8,000 people around the world and killed nearly 800.

這方法很冗長乏味，但在 2004 年 SARS 疫情時已被證明有效，當時 SARS 有 8,000 人確診，約 800 人死亡。

Public health officials say contact tracing is a necessary step before certain businesses can reopen and people can start to return to normal activities.

公衛官員表示，接觸追蹤是企業重新開放、人們回歸正常生活前必須的一個步驟。

Some countries, including South Korea, India, and Singapore, are using smartphone technology alongside traditional techniques to ramp up their contact tracing programs.

某些國家，包含南韓、印度與新加坡，同時並用智慧型手機的技術及傳統方法，來加速他們的接觸追蹤進度。

While the CDC in the U.S. has started a pilot program to ramp up contact tracing in some states, many studies estimate that the U.S. will need hundreds of thousands of additional public health workers before a contact tracing system can really begin nationwide.

雖然美國疾管署已經啟動一個試驗計畫來施行接觸追蹤，許多研究仍指出美國需要更多的公衛員工，才有辦法在全國施行接觸追蹤。

10 second trivia.

十秒問答。

Which of these stories made headlines in 1947?

哪篇報導在 1947 年是頭條？

"Flying saucers" seen in Washington, Communism declared in China, Barbie Doll Makes debut, or First Corvette introduced.

華盛頓的「飛行茶碟」、中國的「啟用共產制度」、芭比娃娃初次登場還是第一個輕武裝快艇的誕生？

A civilian pilot named Kenneth Arnold said he saw flying objects that a reporter mistakenly called flying saucers.

一名叫做 Kenneth Arnold 的民間飛行員說他看到不明飛行物，而一名記者誤稱為「飛行茶碟」。

For decades, the U.S military has been studying aerial encounters with unknown objects, aka UFOS.

數十年來，美國軍方不斷研究在空中遇到的不明飛行物，也就是幽浮。

This week, the Pentagon released three videos that were recorded during U.S. Navy training flights, and they apparently show mysterious airborne objects captured by the plane's infrared cameras.

這週，五角大廈公佈了三段海軍飛行訓練的影片，可以清楚地看到飛機的紅外線攝影機拍到了神秘的飛行物體。

One of the recordings was made in 2004: a pilot who saw that object said it moved rapidly in ways he couldn't explain.

其中一段影像是在 2004 年拍攝到的，機師看到一個以無法解釋的方式快速飛行的物體。

The other two clips were captured in 2015, and in one of those, a pilot can be heard saying the object is a drone.

另外兩段影像則是 2015 年拍攝到的，在其中一段，你可以聽到機師說該物體是一個無人機。

So, was it?

真的是嗎？

The Pentagon says whatever was recorded remains unidentified, and it didn't give any hints as to what it thinks the objects might have been.

五角大廈表示影像中的物體仍未確認身份，且沒有發表它們對於此物體的想法。

The reason the military officially released the videos yesterday after they had been published without permission by other organizations was to help clear up public debate over whether the videos were real and if there's anything more to them.

這些影像之前就已經被其他組織在無授權的情況下公布，而軍方在昨日公布這些影像，是為了釐清大眾對於影像真實度的疑慮。

The military also wants to encourage pilots to report anything strange they see because any unauthorized object in the sky could be dangerous to aviators and U.S military operations.

軍方也鼓勵機師如果看到奇怪物體可以馬上回報，因為天空有任何未授權的飛行物，都可造成航空界或軍方的危險。

Since humans have crisscrossed the skies, they've made several trips to the moon and mapped it as we showed you earlier this week.

人類已經飛越天空，也到了月球上好幾趟，還畫了地圖，就如同我們這週先前給大家看的那樣。

People have also mapped Mars and sent spacecraft to the far reaches of our solar system.

人類同樣也為火星繪了地圖，並派遣太空船到那太陽系的彼端。

So why is it that more than 80 percent of our oceans are still unmapped and unexplored according to the National Ocean Service?

那為何根據美國國家海洋局，全世界超過八成的海洋仍未被探索過？

Like space exploration, deepwater exploration is expensive.

空間探勘、深水域探勘都非常昂貴。

It can be dangerous, it's time consuming, and researchers have trouble getting funding.

任務也有危險性、耗時，且缺乏資金。

But there are some inventors who are finding new ways to go deep.

但有些發明家，發現了前進深水域的新方法。

The latest suit that we're building right now is called an Exosuit, and "exo," very simply, is from exoskeleton, like a crab shell and all your soft meat inside it doing what you want to do.

我們在研發的最新裝備叫做 Exosuit，「exo」是取自於 exoskeleton (外骨骼) 一字，就像螃蟹，你在蟹殼操作外面的身體做想做的事。

So it's kind of like Iron Man come to life.

也有點像鋼鐵人。

My name is Phil Newton, and I've designed and build things to go under the sea, deep under the sea.

我是 Phil Newton，我負責設計可以讓人類到深海底的東西。

The whole idea of being able to get people down into deep water, that huge part of the planet that were denied access to by birth, is a very exciting one.

深海是個深遠龐大，卻又觸摸不到的地方，而這個讓人類可以前進深海的點子，讓我非常興奮。

We build a lot of devices that haven't been built before.

我們建了許多還沒被建過的裝置。

And, that's what makes the whole thing fun.

這讓整件事變得很有趣。

We put this into a hydraulic press.

我們在這裡加入水壓。

In 1985 we built the first of what were called Newt Suits and named after my last name, Newton and the aquatic salamander.

1985 時，我們創造了 Newt Suit，是以我的姓來取的，Newton 然後加上水蠑螈。

So we've learned everything that's wrong with them, and over a period of time came up with a brand new, completely upgraded version called the Exosuit.

從那時起，我們不斷搜集可以改進的地方，並在一段時間後，開發出全新、全面升級的版本，叫做 Exosuit。

And that was for a diving suit.

當時那是潛水服。

There's nothing more than just a big camera case inside the suit.

裡面除了一個大攝影機之外，什麼都沒有。

You're at the same pressure that we were designed to be at, the pressure that we're at right now, and with this suit, you get onto 1000 feet and even deeper and have no pressure effects whatsoever, because inside it is one atmosphere.

在裡面你感受到的壓力，將會跟在平地一樣，因為這就是我們的設計，你可以潛到 1,000 英尺深，但不會受到水壓影響。

(inaudible)

(無法辨識)

Submarines work beautifully as submersible deep workers: the subs are terrific for survey work, so they can zip around shipwrecks, wellheads, all the sort of stuff.

潛水艇在深水功能性很好，它們可以進行調查作業，可以探索沈船遺骸、水源之類的東西。

The suits are better suited for working.

這個套裝則是作業時的好工具。

Your arms are actually in there, your hands are gripping the grippers, and so when you move, it moves.

你的手臂可以操作握把來行動，所以你做什麼動作，套裝也會跟著做。

It's really kind of a paradox, in as much as it has to be absolutely rigid to withstand that high outside pressure at, say, 1000 feet pressure is 500 pounds per square inch.

這其實有點矛盾，該套裝得非常堅固，使它可以承受高壓，如深水 1000 英尺的壓力為每平方英吋承受 500 磅的壓力。

But it has to be flexible, so you could move the arms and legs and work.

但同時又得有行動力，如此才能移動手臂與腳步來作業。

Otherwise, what's the point going down there?

否則下去深水有何意義？

The suit has a tether to the surface, and that tether provides you with power because the suit flies.

該套裝表面有個繩索，該繩索會給你動力，因為該套裝可以飛。

It has thrusters on it, and it flies around on the end of this umbilical.

上頭有推進器，從中間提供動力。

There's optic fiber in the umbilicals so it can take back video.

在裡頭也有光纖，可以傳遞影像。

The option supply system does not come from the surface.

維生系統也不是設置在表面。

The option supply is built into the suit, and the supply is about two full days.

而是設置在套裝裡面，可以使人存活兩個整天。

So why doesn't everybody do it?

那為何大家不這麼做？

Well, first of all, the suits are very hard to build, and they're expensive.

首先，該套裝非常難做，而且成本很高。

They're very expensive.

成本非常高。

So, most difficult thing is getting the price down.

最難的事情，應該就是壓低價格。

Going down in the Exosuit is almost always going down for a purpose.

穿著 Exosuit 下水一定是有目的的。

I want the pilot to be able to accomplish the task, whatever it is, whether photography, welding, cutting, blasting, burning, and not think about the suit at all - you shouldn't even know it's there.

我想要穿著的人可以完成任務，不論是攝影、焊接、切割、爆破、燃燒等等，在做這些事情時能完全不在意套裝，甚至連你有穿套裝這件事都沒感覺。

It has to be unremarkable, the more unremarkable, the better.

這套裝的表現一定要很出色，越出色越好。

I guess what drives me is that there's still so much more to be done.

驅使我的動力是，還有許多可以更好的地方。

It's tremendous to be able to go to greater depths than you've been to ever before and to examine them.

能夠前進並探測人類沒到過的更深的海底，這件事是很棒的。

And when archaeologists and scientists are able to go down there.

而當考古學家與科學家都能到深海的時候。

The deeper they go, the more things they find that they didn't even know existed.

到越深的地方，就能發現越多從前未知的事物。

NASCAR racer Denny Hamlin recently finished last at Talladega.

全美運動汽車競賽協會的賽車手 Denny Hamlin 最近在 Talladega 拿到了最後一名。

Okay, it wasn't a real race.

好吧，這不是真的比賽。

NASCAR has postponed its events because of Coronavirus, but the online game Hamlin was in came to an abrupt end - for him anyway - when his daughter accidentally disconnected him from the server.

NASCAR 因疫情而延期賽事，但 Hamlin 本來在玩的線上遊戲突然結束 (只有他結束)，因為他女兒不小心讓他斷線了。

-Hey, my screen just went black. -Uh-oh.

-欸，我的螢幕沒了。 -喔噢。

Uh-oh was right!

當然要喔噢！

Daddy Hamlin wasn't too happy when the seven-year-old forced him into last place.

當七歲女兒害自己變成最後一名，爸爸 Hamlin 可不是太高興。

Maybe for punishment, she could just take a lap.

或許可以讓她跑一圈來當作懲罰。

But she might be happy that his talent day got away.

但她可能反而會很開心。

It wasn't all fun and games.

這可不是鬧著玩的。

Maybe he seemed too socially distant.

或許他社交距離保持得太好了。

And even if she had to peel out after making his game crash and burn, it's still supposed to be fun when your family comes to the race.

即使女兒在讓爸爸斷線後會被處罰，但有家人在身邊一切都還是美好的。
