What is the Coolest Gas in the Universe?
What is the coldest air temperature ever recorded on Earth?Where was this low temperature recorded ?
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-
peratures at Pluto are about -210℃.How cold is the lowest estimated temperature in the entire universe?
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
and Wieman,have successfully______(59)down a gas to a temperature barely above absolute zero.
They won a Nobel Prize in Physics in 2001 for their work一not a discovery in this case.
Why is the two scientists'work so important to science?
In the 1920s,Satyendra Nath Bose was studying an interesting_______(60)about special light par-
tidles(微粒)we now call photons(光子).Bose had trouble __________(61)other scientists to believe his
theory,so he contacted Albert Einstein. Einstein’s calculations helped him theorize that atoms_______(62)
behave as Bose thought一but only at very cold temperatures.
Scientists have also discovered that ultra-cold(超冷)atoms can help them make the world'S atomic
clocks even__________(63)accurate.These clocks are so accurate today they would oniy lose one second
_________ (64)six million years!Such accuracy will help us travel in space because digtanee is velocity
(速度)times time( d=vt).With the long distances involved in space _______(65),we need to know
time as accurately as possibie to get accurate distance.
选项
_________(55)
A:system
B:energy
C:year
D:rays
答案
A
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。
