mindmap root((AER/AERO)) aerial 1、 Performed in the air.
2、 Performed using an airplane.
🌱They're doing an aerial survey of the whale population, which involves scanning the ocean's surface from an airplane. 🌳Shakespeare himself may have coined this word, in Othello, and later he gave the name Ariel to the famous air-spirit character in The Tempest. An aerialist is an acrobat who performs high above the audience. In painting, aerial perspective is the way an artist creates the illusion that a mountain or city is far away （something that early painters only slowly learned how to do）, usually by making it slightly misty and bluish gray—as if seen through miles of air. An aerial work platform, or "cherry picker," supports a worker at a high elevation on the end of a crane. And aerial itself can be used as a noun, meaning a TV antenna, a forward pass in football, or a high-flying stunt performed by a skateboarder or snowboarder. aerate To supply with air or oxygen.
🌱The garden soil was well aerated, since they had recently plowed in all the compost and manure and even added a box of earthworms. 🌳Faucet aerators and aerating showerheads can be easily installed by homeowners to cut water （and especially hot water） use by as much as 50%. A lawn aerator removes little plugs of soil in order to let air deep into the soil, greatly improving the quality of soil that may have gotten too compacted. And a pond aerator, such as a fountain, is a necessity for an ornamental pond with no stream feeding it, since oxygen in the water is necessary to prevent the growth of algae and allow fish to live. aerobic 1、 Living or occurring only in the presence of oxygen.
2、 Involving or increasing oxygen consumption.
🌱Trainers measure a person's aerobic capacity by means of the VO2 max （"maximum volume of oxygen"） test. 🌳Aerobic exercise is exercise that takes an extended amount of time—usually ten minutes or more—but is usually performed at only moderate intensity. Running, swimming, bicycling, and cross-country skiing are classic aerobic exercises. In 1968 a best-selling book called Aerobics introduced a system of exercise for increasing the body's ability to take in and use oxygen, and today aerobics classes, often mimicking such outdoor exercise as running and bicycling, take place every afternoon in thousands of gyms and YMCAs across the country. Aerobic exercise particularly strengthens the heart and lungs, but usually has many other good effects as well. Aerobic bacteria, which need oxygen to live, are essential for breaking down living matter so that it returns to the soil. They include the famous intestinal E. coli, as well as the staph and strep bacteria that can make a visit to the hospital risky. anaerobic 1、 Living or occurring in the absence of oxygen.
2、 Relating to activity in which the body works temporarily with inadequate oxygen.
🌱He's never run a mile in his life, and everything he does at the gym is anaerobic. 🌳In Greek, the prefix a- or an- means "not" or "without," and bios means "life." Anaerobic sports and exercise, such as gymnastics, weight lifting, and sprinting, are of high intensity but short duration, so they don't involve much oxygen intake. Anaerobic exercise triggers a different type of cell activity from aerobic exercise. As a result, it doesn't do much for your heart and lungs and it doesn't burn off fat; what it does do is build muscle. Anaerobic bacteria are bacteria that live without oxygen. They're responsible for several nasty conditions, including tetanus, gangrene, botulism, and food poisoning. They often live in deep wounds, so a bad dog bite—or, even worse, a human bite—can be dangerous, since the mouth is full of anaerobic bacteria. But most anaerobic bacteria are harmless, and many are essential to our lives.
