高分英语作文1：submarine
Scuba diving (originally the acronym for self-contained scuba, now widely considered as a word) is a form of underwater diving in which divers use a set of scuba breathing apparatus to breathe underwater, while early diving relied entirely on air pumped from the surface. Scuba divers carry their own source of breathing gas (usually compressed air, which makes They have more freedom than with air pipes - surface supply and scuba diving allow divers to stay underwater much longer than with breathing techniques such as snorkeling and free diving. According to the purpose of diving, divers usually move underwater by attaching swimsuits, but the external driving force can come from underwater vehicles or sleds pulled out of the water.
Early diving experimenters soon found that, in addition to normal atmospheric pressure, it was not enough to provide air to breathe comfortably under water. Water exerted more and more pressure on the chest and lungs, per foot per square inch. Therefore, the respiratory pressure inhaled must be almost completely opposite to the surrounding or surrounding pressure to inflate the lungs.
Usually, breathing through pipes more than three feet under water becomes difficult. Modern demand valve regulators provide breathing gas under ambient pressure, ensuring that divers can breathe in and out naturally and almost effortlessly, regardless of depth, because divers' noses and eyes are covered by diving masks, divers cannot breathe through their noses, but dive in full face Except in the case of masks, breathing through the regulator's mouth quickly becomes second nature.

通常情况下，通过水下三英尺以上的管子呼吸变得困难现代需求阀调节器提供环境压力下的呼吸气体，确保潜水员可以自然地、几乎毫不费力地吸气和呼气，而不管深度是多少，因为潜水员的鼻子和眼睛被潜水面罩覆盖，潜水员不能通过鼻子呼吸，但戴着全脸潜水面罩的情况除外，从监管者的口中吸气很快就成了第二天性。
