People often vaguely refer to "the middle of nowhere", but as it turns out, scientists have actually figured out precisely where that point is. Point Nemo, the most remote location on Earth, is so far removed from civilization that the closest humans to that location at any given time are likely to be astronauts. Point Nemo is officially known as "the oceanic pole of inaccessibility", or the point in the ocean farthest from land. Located at 48°52.6'S 123°23.6'W, the spot is quite literally the middle of nowhere, surrounded by more than 1,000 miles of ocean in every direction. There are no human inhabitants anywhere near Point Nemo. And scientists chose to call the location "Nemo" because it is Latin for "no one" and as a reference to Jules Verne's submarine captain from 20,000 Leagues Under the Sea.The location is so isolated that the closest people to Point Nemo are not even on Earth. Astronauts aboard the International Space Station are around 258 miles from the Earth's surface at any given time. Since the inhabited area closest to Point Nemo is more than 1,000 miles away, the humans in space are far closer to the pole of inaccessibility than those on land.Not even the man who first calculated the precise location of Point Nemo has ever visited it. In 1992, Croatian survey engineer Hrvoje Lukatela set out to find the exact point in the Pacific that was farthest away from any land using a computer program. It is very possible that no human has ever passed through Point Nemo's exact coordinates. As for non-human inhabitants, there aren't very many of those around Point Nemo either. Point Nemo's coordinates fall within the South Pacific Gyre, an enormous rotating current that prevents nutrient-rich water from flowing into the area. Without any food sources, sustaining most life in this part of the ocean is impossible.Point Nemo does, however, have at least one other eerie claim to its name. Due to its remoteness and distance from shipping routes, the area around Point Nemo was chosen as a "spaceship graveyard". According to CNN, NASA first started using the region in 1971. Since then, more than 263 pieces of space junk have crashed into the area, including some of the world's greatest spacecraft, the Russian Mir space station and NASA's first space station, Skylab. （1） Why is Point Nemo referred to as the "oceanic pole of inaccessibility"? A . It is the farthest point from any land. B . It is the deepest point in the ocean. C . It is located at the center of the Pacific Ocean. D . It is a place that only astronomers have ever visited. （2） What can be learned about the isolation of Point Nemo? A . It is frequently visited by marine biologists. B . It is within reach of commercial shipping routes. C . The nearest humans to Point Nemo are often astronauts. D . There are several small islands nearby. （3） Which of the following is True about the environmental conditions around Point Nemo? A . The area is rich in marine biodiversity due to its isolation. B . The strong currents of the South Pacific Gyre support a thriving ecosystem. C . The region is frequently visited by marine researchers for its unique ecosystem. D . The lack of nutrients makes it difficult for most marine life to survive in the area. （4） What is the crucial aspect when choosing an area as a "spaceship graveyard"? A . Proximity to major coastal cities. B . Depth of the ocean at the chosen location. C . Distance from any landmass and human activity. D . Presence of strong ocean currents that could disperse debris. 答案： A C D C
