What Is the Coolest Gas In The Universe?

What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was -91℃,which ____ (51)in Antarctica(南極洲)in 1983.

We encounter an interesting situation when we discuss temperatures in ____(52).Temperatures in Earth orbit(軌道)actually range from about +120℃ to -120℃.The temperature depends upon ____(53)you are in direct sunlight or 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.Scientists estimate temperatures 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-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 particles(顆粒)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-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 only lose one second ____(64)six million years! Such accuracy will help us travel in space because distance is velocity times time(d=vt).With the long distances involved in space ____(65),we need to know time as accurately as possible to get accurate distance.

51 D 本題考查四個(gè)動(dòng)詞的意思。A 為"操作,運(yùn)行";B 為"打開(kāi),開(kāi)張";C為 "提供, 提出";D為"發(fā)生,出現(xiàn)"本句要表達(dá)"1983 年南極洲出現(xiàn)了地球上記錄到的最低溫度"。答案為 D。

52 A 本題是對(duì)名詞意思的考查。A為"太空";B為"星星";C為"地球";D為"行星"。從文章的第三段第一句話可以看出,本段討論太空的溫度。答案為 A。

53 D 本題是對(duì)連接詞意思和用法的考查。A為"何地"; B為"什么";C為"何時(shí)";D為"是否"。本句從句中不缺少任何成分,只是想表達(dá)"溫度取決于你是否向陽(yáng),或是向陰"。答案為D。

54 D 本題是對(duì)副詞意思的考查。A為"難過(guò)地";B 為"重復(fù)地"; C為"自由地";D 為"安全地"。本句的意思是"我們的身體無(wú)法安全耐受零下 120 度的溫度"。答案為 D。

55 C 本題要表達(dá)的意思是"太陽(yáng)系"。 A是"能量";B是"年9";C是"系統(tǒng)";D 是 "射線"。只有 C符合題意。

56 C 本句要表達(dá)的是兩個(gè)對(duì)立的意思:離太陽(yáng)越近,我們感到越熱;離太陽(yáng)越遠(yuǎn),我們感到越寒冷。從所給介詞的含義來(lái)看,只有 away有"開(kāi)"的意思。答案為C。

57 A 本段要表達(dá)的意思是 "溫度取決于與太陽(yáng)的距離",所以本句的空格應(yīng)填寫 location,表達(dá)"位置"這個(gè)概念。選項(xiàng) B 是"教育";C 是"地位";D 是"知識(shí)"。答案只能為A 。

58 B 從意思上來(lái)考慮,選項(xiàng) A 為"有趣的";選項(xiàng) B 是"不可能的";選項(xiàng) C 是 "合理的";D是"必要的"。文章要表達(dá)"我們被告知絕對(duì)零度之下原子是無(wú)法運(yùn)動(dòng)的,所以不可能存在比絕對(duì)零度更低的溫度"。從意思上考慮應(yīng)為"不可能的",答案為B。

59 B 從詞意來(lái)考慮,選項(xiàng) A為"燃燒";B為"冷卻";C為"吹";D為"切、割"。本句的意思是"兩位科學(xué)家將氣體冷卻到接近絕對(duì)零度"。答案為 B。

60 D 下文有提示,科學(xué)家 SatyendraNath Bose 做了有關(guān)光子的理論研究。A 為"發(fā)明";B 為"實(shí)驗(yàn)";C 為"紙張、論文";D 為"理論"。答案為 D。

61 C 從詞意上考察。A為"強(qiáng)迫";B 為"乞求";C為"說(shuō)服";D 為"命令"。本句的意思是"因?yàn)?Bose 難以說(shuō)服其他科學(xué)家相信他的理論,所以他就聯(lián)系了愛(ài)因斯坦"。答案為 C。

62 B 根據(jù)上下文判斷可以排除選項(xiàng) C 和D。will 可用來(lái)表示"在一定的情況下通常會(huì)……',又因?yàn)楸揪渲骶涞臅r(shí)態(tài)為一般過(guò)去式,所以從句中的助動(dòng)詞使用過(guò)去式 would。 本題答案為B

63 C 句中的 even 是對(duì)比較級(jí)的修飾,所以本題答案為 C,表達(dá)的意思是"甚至更準(zhǔn)確"。

64 A 本句要表達(dá)的意思是"這些鐘準(zhǔn)確到每 6 百萬(wàn)年才差一秒鐘",所以應(yīng)該選擇every,表達(dá)"每一",其與 each 的區(qū)別是 every帶有頻率的含義,而 each 沒(méi)有這種意思。

65 D 本句要表達(dá)的意思是"在長(zhǎng)距離的太空旅行時(shí),我們更需要準(zhǔn)確的時(shí)間以判斷準(zhǔn)確的距離"。只有選項(xiàng) D"旅行"最合適。選項(xiàng) A 為"站";B 為"工藝";選項(xiàng) C 為"年齡、時(shí)代"。
