The coldest recorded temperature on Earth was －91℃, which_____ (51) in Antarctica（南极洲）
in 1983.
We encounter an interesting situation when we discuss temperatures in_________(52).Temperatures
in Earth orbit（轨道）actually range from about +120℃ to －120℃. The temperature depends upon
______(53)you are in direct sunlight or in shade.Obviously，－120℃ is colder than our body can
________ (54)endure.
The space temperatures just discussed affect only our area of the solar________(55).Obviously,it
is hotter closer to the Sun and colder as we travel__________(56)from the Sun,Scientigtg egtimate tern-

Again,it depends upon your_________(57).We are taught it is supposedly__________(58)to have a
temperature below absolute zero,which is－273℃，at which atoms do not move.Two scientists,Cornell

参考解析
解析：最低温度这种现象只能发生（occur)，而不能是其他的行为；而且which在此句中作指 物的主语时，其谓语只能用不及物动词。
由第三段的第一句话可知，此处填“space”与其对应。
由后面的or可知选whether , whether...or…是固定搭配，意为“是······还是······“。
身体只能为是否“安全地”承受，而不是“悲伤地’，、“重复地”、“自由地”承受。
solar system是专有名词，意为“太阳系”。
travel away是“远离”的意思，由句子中的比较关系可知，此处是指远离太阳。
由前面的离太阳近，温度高，反之亦然，可知此处指你所处的位置不同，温度高低也不同。
按常识来讲，在－273℃原子能动是不可能的。
cool down是固定短语，意为“冷却”。
由本段中第二句的“his theory”可知此处应填与之对应的“t1tneory” 。
Bose只能是“使别人信服”他的理论，而不能“迫使”、“请求”、“命令”。
would在此表示推测，意为“大概，会”。
even more修饰accurate，表示更加精确。
every＋时间段，表示“每······时间”。此外表示“每6百万年”。
只有旅行（travel）才能与距离相关，所以此处的"space travel”指太空旅行。
