考點5 space station太空站
space不可數名詞，意為"太空，空間"，一般情況下不與冠詞連用，但如果space前面有表示太空情況的形容詞（如dark,cold,airless）修飾，則可與定冠詞連用。
the earth travels around the sun in space.地球在太空中圍繞太陽旋轉。
辨析：space,room與place
space作"太空"講時，是不可數名詞；作"空間，空地"講時，可與room互換。
room作"房間"講時是可數名詞；作"空間，地方"講時是不可數名詞，指可以容納東西或其他目的而可占據、使用的空間。
make room for...為...騰出空間
place 指某一具體"地點，地方"，是可數名詞。
