Spacewalk!
Most people don't know that the anniversary of an important event in space exploration occurred last month. On March 18, 1965, spaceman Aleksi Leonov became the first human to complete an Extra Vehicular Activity (EVA) or spacewalk. It marked the first time that a human was able to leave a spacecraft and operate in the emptiness of space. It is a dangerous procedure, but one that is vital for the success of manned space missions.
In space, a spacesuit must protect people from extreme cold and heat, provide air to breathe, and remove extra carbon dioxide. Too much of it, and the spacesuit becomes firm and difficult to move in. Too little of it, and astronauts can become dangerously sick after returning to their spacecraft.
Astronauts now perform complex jobs in the emptiness of space in modern spacesuits. They have logged many hours repairing and upgrading equipment on satellites during EVAs. On July 20th, 1969, American astronaut Neil Armstrong set foot on the moon for the first time. There is no atmosphere on the moon, but there is gravity—about 17 percent of Earth's, which means Neil needed a special suit for walking on the moon's surface. Suits for the moon are equipped for exploration far from any vehicles, including tough boots that can resist cuts from the rough surface while walking. But sharp rocks weren't the only danger to astronauts.
The moon surface is covered with a fine and flour-like dust which consists of small particles (颗粒) left over from the numerous meteorite (陨石) strikes on the moon. When astronauts would leave the moon's gravity, the dust on their suits began floating all over. It got into delicate equipment inside the spacecraft and the astronaut's eyes and lungs. As different space agencies plan for returning people to the moon, new EVA suit designs will have to take something else into account. Keeping astronauts safe also means keeping their suits clean.
A. However, EVAs don't just happen in empty space.
B. It sticks to everything, eventually causing joints and seals to fail.
C. Spacesuits also have to maintain ideal air pressure during a spacewalk.
D. Unfortunately, most people have no idea about space exploration or spacesuits.
E. Without the ability to work in space, we are unable to keep our space programs functional.
F. There are a few things that must be taken into account to make an EVA both safe and effective
Learning a second language

Is Cash Becoming Outdated?
When he rolls into a gas station to fill his tank, Barkhad Dahir doesn't get out of his car. He pushes a few buttons on his cellphone and within seconds he has paid for the fuel. With the same quick pushes on his phone, he pays for virtually everything he needs: groceries at the supermarket, a few oranges from a market stall, or a cup of sweet milky tea from a café. Mr. Dahir boasts, "Even lying in bed, you can be paying your bills."
Electronic payments offer consumers convenience, provide revenue for banks, credit card companies and payment processors, and offer merchants improved cash flow and convenience. "I don't even carry money any more," says Adan Abokor, a democracy activist. "I haven't seen cash for a long time. Almost every merchant, even hawker (小贩) on the street, accepts payment by cellphone. There's no waiting for it and no counting of cash."
The system is impressively simple and secure. Purchases are made by dialing a three-digit number, entering a four-digit PIN, and then entering the retailer's payment number and the amount of money. Both customers and merchants receive text messages to confirm the payment.
Clearing up cash payments has several advantages as well. The printing and handling of money is expensive. Cash payments can be anonymous and hard to track criminal activities to be conducted in secret. Many governments favor reducing cash dealings in order to better monitor and understand the activities of their citizens. The Swedish government has been discussing the removing of cash since 2010.
However, some people doubt what members of a cashless society do when the power goes off. Do they choose to barter (物物交换) and rob? Do they sit at home and wait? What happens to people who rely on their cellphones to process money dealings when cell service and the Internet are interrupted? A world affected by terrorism and increasingly violent weather may not yet be ready to abandon currency. "Ironically, the day after the largest bank in Norway, DNB, proposed ending all cash dealings, I went to my local grocery store and when I tried to pay by phone, I was told that I needed to go to the ATM to get cash because the system was broken." said an interviewee.
Other people fear that electronic payments may create security and fraud risks and enable dealings to be tracked and reported. Privacy, security and convenience are all important factors in the adoption of electronic payment technology. New technologies which balance and address these factors may enable people to remove cash.
