[時事英文] 疫情下各國強化監控，健康與隱私不可兼得？
　
It is essential that the government enact measures to keep us safe and healthy. At the same time, we need a framework that prevents governments and companies from overstepping their bounds. How much data should they collect? How should measures be enforced? Are these measures temporary and limited to times of crisis? These are questions we need to think about now.
　
1、enact measures 實行措施
2、overstep the bounds 超出界線*
3、temporary measures 臨時的措施
　
政府必須採取措施以保障我們的安全與健康。同時，我們需要一個框架，以確保政府與公司不會踰越他們的界線。他們該搜集多少資料？該如何執行措施？ 這些措施是臨時性的並僅限於危機時期嗎？這些是我們現在需要思考的問題。

紐約時報報導：
　
In South Korea, government agencies are harnessing surveillance-camera footage, smartphone location data and credit card purchase records to help trace the recent movements of coronavirus patients and establish virus transmission chains. In Lombardy, Italy, the authorities are analyzing location data transmitted by citizens’ mobile phones to determine how many people are obeying a government lockdown order and the typical distances they move every day. About 40 percent are moving around “too much,” an official recently said. In Israel, the country’s internal security agency is poised to start using a cache of mobile phone location data — originally intended for counterterrorism operations — to try to pinpoint citizens who may have been exposed to the virus.

在韓國，政府機構正在利用監控影像、智慧型手機的定位數據和信用卡消費記錄來幫助追蹤冠狀病毒患者的近期活動，並確立病毒傳播鏈。在義大利倫巴底，當局正在分析市民手機傳送的定位數據，以確定有多少人遵守政府的封鎖令，以及他們每天通常行走的距離。一位官員最近說，大約有４０％的人走動得「太多」。在以色列，國內安全部門準備開始使用手機定位數據的暫存－－最初是用於反恐行動－－以精確尋找可能已感染該病毒的國民。

Yet ratcheting up surveillance to combat the pandemic now could permanently open the doors to more invasive forms of snooping later. It is a lesson Americans learned after the terrorist attacks of Sept. 11, 2001, civil liberties experts say. Nearly two decades later, law enforcement agencies have access to higher-powered surveillance systems, like fine-grained location tracking and facial recognition — technologies that may be repurposed to further political agendas like anti-immigration policies. Civil liberties experts warn that the public has little recourse to challenge these digital exercises of state power.

然而，為了對抗現在的全球性流行病加強監控，可能會為今後進行更具侵入性的竊聽打開永久的大門。公民自由專家說，這是美國人在２００１年９月１１日恐怖攻擊後學到的教訓。９１１事件發生近二十年後，執法機構如今掌握著更強大的監控系統，例如細緻精確的定位追蹤和臉部辨識－－這些技術可能會被重新用於反移民政策等進一步的政治議題。公民自由專家警告，公眾幾乎沒有辦法挑戰這些由國家實施的數位行動。

In hundreds of cities in China, the government is requiring citizens to use software on their phones that automatically classifies each person with a color code — red, yellow or green — indicating contagion risk. The software determines which people should be quarantined or permitted to enter public places like subways. But officials have not explained how the system makes such decisions, and citizens have felt powerless to challenge it.
　
21、indicate 指出；表明
22、contagion risk 感染風險
23、quarantine 隔離；檢疫
　
在中國的數百個城市，政府要求市民在手機上使用一種軟體，可以自動用顏色代碼－－紅、黃、綠－－給每個人分類，以顯示感染風險。這個軟體決定哪些人應該被隔離，或是可以進入地鐵等公共場所。但官員們並沒有解釋系統如何做出這樣的決定，市民們也覺得無力挑戰它。

In Singapore, the Ministry of Health has posted information online about each coronavirus patient, often in stunning detail, including relationships to other patients. The idea is to warn individuals who may have crossed paths with them, as well as alert the public to potentially infected locations. On Friday, Singapore also introduced a smartphone app for citizens to help the authorities locate people who may have been exposed to the virus. The app, called TraceTogether, uses Bluetooth signals to detect mobile phones that are nearby. If an app user later tests positive for the virus, the health authorities may examine the data logs from the app to find people who crossed their paths. A government official said the app preserved privacy by not revealing users’ identities to one another.
　
24、stunning detail 驚人的細節
25、cross paths 相遇；交集
26、data logs 數據日誌
27、cross sb's path （偶然）與某人相遇
　
在新加坡，衛生部在網路上公布了每個冠狀病毒患者的訊息，通常帶有驚人的細節，包括與其他患者的關係。這是為了警告可能與他們相遇的人，並提醒公眾注意潛在的感染地點。上週五，新加坡還推出了一款供國民使用的智慧型手機應用程式，幫助當局找到可能接觸過該病毒的人。這款名為「TraceTogether」的應用程式使用藍牙訊號偵測附近的手機。如果一名用戶後來檢測出病毒陽性，衛生當局可能會檢查該應用程式的數據日誌，以便找到與他們有接觸的人。一名政府官員表示，該應用程式通過不向用戶彼此透露身份來保護隱私。

In New York this month, Mayor Bill de Blasio posted details on Twitter about a lawyer in Westchester County who was the second person in the state to test positive for the virus — including the name of the man’s seven-person law firm and the names of the schools attended by two of his children. A few hours later, The New York Post identified the lawyer by name and was soon referring to him as “patient zero” in the coronavirus outbreak in New Rochelle.

In a response posted on Facebook, Adina Lewis Garbuz, a lawyer who is the wife of the man, Lawrence Garbuz, pleaded with the public to focus instead on the personal efforts the family had made to isolate themselves and notify people who came into contact with them. “We would have preferred this all remain private,” Ms. Garbuz wrote in the Facebook post, “but since it is no longer, I wanted to at least share some truths and allay people’s fears.”

短程起飛、垂直降落的F-35B，看他起飛降落，感覺好像在看哈利波特：「這是什麼妖術？」XDD

Amy Butler here. As senior Pentagon editor, there are perks to being a scribe. May 26, I had the opportunity to witness aviation history with a small group of reporters invited to the USS Wasp amphibious ship to witness a few hours of the first-ever F-35B Operational Test (OT-1) trails off the coast of North Carolina. I'm posting some of the many videos I collected to give our readers a sense of what we saw on the boat.

During OT-1, actual Marines -\-\ not test overseers -\-\ are operating the six F-35Bs that embarked May 18 for the tests; this includes pilots and maintainers. During DT (developmental testing), we got to see firsthand the first vertical landing and short takeoff at sea, but in OT-1, the Marines are demonstrating a cadence to operations to gain confidence the single-engine, stealthy fighters can assimilate into an air wing onboard the amphibious ship, which will include other platforms: the MV-22, CH-53E/K, AH-W/Z and unmanned air systems among them. This is all leading up to what the operational debut of the F-35B, slated in July.

This is a long video -\-\ 8 plus minutes. But, if you stick with it, here's what you'll see. And, a word of caution. Turn down your speakers or headphones, or grab a cranial. Its very loud.

F-35B taxis from parking and preps for takeoff (a DV is giving the pilot signals -\-\ you can see him in blue next to the yellow shirt at far right).
1:19: Notice when the lift fan doors open and nozzle angles down (the scorch marks are from repeated take offs at this 400 ft. position).
2:10: F-35B conducts short takeoff.
2:32: A second F-35 approaches for a vertical landing. Notice the nozzle's tiny corrections during the hover, slide over the deck and descent. A typical descent is about 7 ft. per second.
3:38: This F-35 clears the deck, maneuvers to parking area.
That voice you may hear is USMC Lt. Gen. Jon Davis, deputy commandant for aviation, explaining to a reporter that the takeoff point for this round of trials is 400 ft. As the next jet taxis, you can see scorch marks around the 550 ft. mark, where jets have commenced launch at 500 ft. earlier in OT-1.
4:11: Depending on how big your screen is you can see the first F-35B that took off flying in the pattern just above the cloud line to approach for a landing.
5:27: This F-35B is visible behind the ship, control surfaces deployed slowing the aircraft with doors open. At this point the nozzle is rotating and will be fully at 90 deg. once the hover is commanded.
6:22: Pilot slides the F-35 B over the deck (you can see those scorch marks in the Thermion non skid where previous landings have occurred) and comes to a brief rest. As a note: Navy ship operators onboard say they are monitoring the performance of the Thermion but detected no red flags thus far into the trials.
7:15: Yellow shirt commands taxi forward for another takeoff from 400ft.
8:10: Yellow shirt commands power (Sorry for the finger -\-\ was quite windy and lots of engine blowback -\-\ can't drop Av Week's iPhone!).
8:28: Takeoff

That was our welcome on deck.

0:25 Forex Trading Tip #1
Enter your trades near market structure. So let me share with you how not to do it, right? So firstly, right, often, traders will look at a chart, right. So, let's say, for example, the red one here is your stop loss. The green one is your entry point. And the blue one is your, so-called take profit level. So, traders, they will see this chart, and they say, oh, man, the price is, you know, coming down, lower and lower. Let me, you know, hop on board before you know, I miss the move.

2:51 Forex Trading Tip #2
The second tip is this, right, is that you want to trade breakouts with buildup. So what is buildup, right? Let me explain. For those of you who have been following me a while now, you're already a pro at this. So a buildup means, right, a tight consolidation where the range of the candles gets smaller and smaller. So you can see that over here, this blue box, this is what we call a buildup over here.

4:10 Forex Trading Tip #3
This is a sign of strength that a market is likely to breakout higher. Another variation of this, right, is what we call higher lows into resistance. This is a sign of strength, as well. Notice, you see the higher lows, higher lows, higher lows, higher lows, into resistance. The concept is somewhat similar to the buildup, but this time 'round, it's telling you that buyers are willing to buy at this higher price instead. It's why you see higher lows into resistance. Right, so this is also another sign of strength, right.

4:28 Forex Trading Tip #4
The fourth tip that I want to share with you is what I call the first pullback. So often, right, the price, it can break out. And if it breaks out, right, you might have missed the move, right, if you didn't catch the breakout. But don't worry, because more often than not, right, the price will give you a chance to re-enter, to catch the trend.

5:23 Forex Trading Tip #5
The fifth thing that I want to share with you is to set your stop loss, right, away from market structure, because often, what traders do is that let's say, the market is in a range, okay? They go long, right, and price hits up higher, they go long over here. Where do they put their stop loss? They put their stop loss just below this level of support. And what happens? Well, the market could just as well come down lower, trigger your stop loss, and then continue higher. So this is why, right, you don't want to put your stop loss just below support, or just above resistance.

7:22 Forex Trading Tip #6
The sixth tip that I want to share with you is entry technique, right, to profit from traders who long breakout, and then they got trapped. Here's how it works. So this is what I call the false break set-up. So you can see that over here, area of resistance, resistance, market broke out of resistance on this candle. You can imagine, right, that actually at one point in time, this candle was looking bullish, something like this, okay?

9:16 Forex Trading Tip #7
And the last tip that I want to share with you is this, right. Use limit order for a better risk-to-reward on our trades. So let me share with you an example. So you can see over here, alright, this is a chart of Euro Yen for our timeframe. How do I know that, because it's over here. Okay, so, this is a very typical set-up that traders will trade prices at an area of support, right? Coming to an area of support, right. Now this step once, twice, you can mark up your support level. It's going to be quite obvious. And then, this bullish reversal candle is so bullish, right? You suddenly just hit a massive reversal, and close near this highs over here.

เปิดตัว All-New 2020 Toyota Corolla Altis Sedan (โตโยต้า โคโรลล่า อัลติส ซีดาน) เวอร์ชั่นอเมริกา เฉพาะชาวอเมริกัน

CARMEL-BY-THE-SEA, Calif. (Nov. 15, 2018) -- With more than 46 million Toyota Corollas sold globally since its introduction in 1966, it would be difficult to find a driver who did not recognize the name. Everyone, it seems, has a Corolla story. Many, though are going to be doing double takes when they see the re-imagined and reconfigured 2020 Toyota Corolla sedan. And that’s exactly the point.

The 12th-generation Toyota Corolla made its arrival in two chapters: the all-new Corolla hatchback arrived earlier this year, and now comes the current best-selling Corolla body style, the sedan. Both are based on the Toyota New Global Architecture (TNGA), which is far more than a new body structure, bringing together new approaches to engineering, design, assembly, and materials.

TNGA transforms both Corolla styles into drivers’ delights while also bolstering the model’s renowned value and reliability. Both draw from the same DNA and share powertrains. It’s no surprise, then, that the 2020 Corolla sedan dramatically elevates this model’s focus on comfort and refinement while also infusing it with the Corolla hatchback’s feisty personality.

The Corolla sedan’s bold new look is a perfect reflection of the bumper-to-bumper, wheels-to-roof transformation that has taken place. The TNGA platform means an available engine that produces more power than its predecessor yet delivers better fuel efficiency. TNGA imbues the Corolla sedan with greater agility, yet also with its smoothest, quietest ride. TNGA also means an elevated feeling of quality in every surface, switch and control the driver sees and touches. And, critically, TNGA delivers on Toyota’s commitment to driver and passenger safety with the Toyota Safety Sense 2.0 suite of active safety systems – standard on every Corolla sedan model.

Design Transformation
Toyota shook up the midsize sedan ranks with the new-generation Camry, and now the compact sedan segment is in for a jolt with the 2020 Corolla sedan. From every angle, the new Corolla sedan looks lower and leaner, tauter and tighter. Powerful fender flares and generously curved fender top surfaces accent its sculpted, athletic core.

The design team called its working concept “shooting robust,” because they were shooting for a robust, confidence-inspiring stance. Yet, they had to maintain ample space for practical, real-world use. That’s why people buy sedans, after all.

The 2020 Corolla sedan rides on a 106.3-inch wheelbase, like its predecessor, yet any commonality ends there. Corolla sedan’s dynamic performance and stance benefit greatly from wider front (+0.47 in.) and rear (+0.87 in.) track dimensions. The front overhang was shortened by 1.3 in., and the rear overhang extended by more than half an inch. Height was reduced 0.8 in., and the hood lowered 1.4 in. for better forward visibility, made possible by mounting the engine lower. Those changes, plus many others, reduce the center of gravity by 0.39 in. That’s just one part of the transformation that has turned the Corolla sedan into a highly nimble, engaging machine to drive.

The bold front fascia details vary by model grade, with the SE and XSE putting on the sportiest face, including a body-color chin spoiler and aero stabilizing fins to emphasize the wide stance. The slim, J-shaped Bi-Beam LED headlamps wrap deeply into the front fenders and give the Corolla sedan a steely stare and a distinct nighttime signature. The sporty SE and XSE grades use triple J-shaped clearance lamps with LED light guides along with LED turn signals, creating a unique design signature.

The available Adaptive Front-lighting System (AFS) provides a wider field of light and steers the low beam in the direction of the turn, based on steering angle and vehicle speed.

The rear leaves a distinct lighting impression as well, with narrow combination lamps that wrap deeply into the fenders. All 2020 Corolla sedan models use LEDs, the type and style varying by model grade. The sporty grades feature smoked outer light lenses.

What better way to showcase the Corolla sedan’s dramatic new sheet metal than with a dramatic new color? The new hue is a highly iridescent Celestite Grey Metallic. The rest of the palette includes Blizzard Pearl, Super White, Classic Silver Metallic, Black Sand Pearl, Barcelona Red, Blue Crush Metallic and Blueprint.

Nissan reveals Nissan Sylphy EV Zero Emission at Auto China 2018.

Nissan will show three electric vehicles at Auto China 2018, as part of a lineup that offers an exciting glimpse of the future and shows the company’s strength and depth in the highly competitive and growing Chinese market.

A new electric model will debut at Auto China 2018 in Beijing and take center stage alongside the new Nissan LEAF and the Nissan IMx KURO electric crossover concept vehicle.

The new model will help meet growing demand for electric cars in China and highlights Nissan’s commitment to electrification under the company’s midterm plan, Nissan M.O.V.E to 2022, and Dongfeng Motor Co., Ltd.’s TRIPLE ONE plan. Nissan will also showcase its e-POWER electrified powertrain technology.

Introduced last October, the new Nissan LEAF won the “2018 World Green Car” award at the New York International Auto Show in March. The model is the flagship of Nissan Intelligent Mobility, the company’s vision for changing how cars are powered, driven and integrated into society. With more than 300,000 sold worldwide since its initial launch in 2010, the Nissan LEAF is the world’s best-selling electric vehicle.

The Nissan IMx KURO is making its China debut after being unveiled earlier this year at the Geneva Motor Show. This electric crossover concept vehicle strengthens the link between car and driver as a close, reliable partner that delivers a safer, more convenient and more exciting drive.

The IMx KURO features Nissan’s Brain-to-Vehicle technology, the first system of its kind. The technology interprets signals from the driver's brain to help the vehicle’s autonomous and manual systems learn from the driver.

In addition to its lineup of electrified cars and technologies, Nissan will introduce the all-new Nissan Terra. The Terra is the first new vehicle from Nissan’s frame and LCV division under the Nissan M.O.V.E. to 2022 and TRIPLE ONE plans. Practical, authentic and designed to go anywhere, the frame-based SUV will soon arrive in China to meet customer demand for an unprecedented driving experience.
