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
You walk into the classroom, look at that white piece of paper in front of you and are told you've got an hour and a half to do it. That can make anyone nervous, but here is the guide to stay calm.

Age has its privileges in America, and one of the more prominent of them is the senior citizen discount. Anyone who has reached a certain age — in some cases as low as 55 — is automatically entitled to dazzling array of price reductions at nearly every level of commercial life. Eligibility is determined not by one's need but by the date on one's birth certificate. Practically unheard of a generation ago, the discounts have become a routine part of many businesses — as common as color televisions in motel rooms and free coffee on airliners.
People with gray hair often are given the discounts without even asking for them; yet, millions of Americans above age 60 are healthy and solvent(有支付能力的). Businesses that would never dare offer discounts to college students or anyone under 30 freely offer them to older Americans. The practice is acceptable because of the widespread belief that “elderly” and “needy” are synonymous (同义的). Perhaps that once was true, but today elderly Americans as a group have a lower poverty rate than the rest of the population. To be sure, there is economic diversity within the elderly, and many older Americans are poor. But most of them aren't.
It is impossible to determine the impact of the discounts on individual companies. For many firms, they are a stimulus to revenue. But in other cases the discounts are given at the expense, directly or indirectly, of younger Americans. Moreover, they are a direct irritant in what some politicians and scholars see as a coming conflict between the generations.
Generational tensions are being fueled by continuing debate over Social Security benefits, which mostly involve a transfer of resources from the young to the old. Employment is another sore point. Buoyed (支持) by laws and court decisions, more and more older Americans are declining the retirement dinner in favor of staying on the job — thereby lessening employment and promotion opportunities for younger workers.
Far from a kind of charity they once were, senior citizen discounts have become a formidable economic privilege to a group with millions of members who don't need them.
It no longer makes sense to treat the elderly as a single group whose economic needs deserve priority over those of others. Senior citizen discounts only enhance the myth that older people can't take care of themselves and need special treatment; and they threaten the creation of a new myth, that the elderly are ungrateful and taking for themselves at the expense of children and other age groups. Senior citizen discounts are the essence of the very thing older Americans are fighting against — discrimination by age.
