2015年職稱英語考試理工類試題練習及答案2
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.

答案：
56 C 本句要表達的是兩個對立的意思：離太陽越近，我們感到越熱;離太陽越遠，我們 感到越寒冷。從所給介詞的含義來看，只有 away有"開"的意思。答案為C。
57 A 本段要表達的意思是 "溫度取決于與太陽的距離"，所以本句的空格應填寫 location，表達"位置"這個概念。選項 B 是"教育";C 是"地位";D 是"知識"。答案只能為A 。
58 B 從意思上來考慮，選項 A 為"有趣的";選項 B 是"不可能的";選項 C 是 "合理的";D是"必要的"。文章要表達"我們被告知絕對零度之下原子是無法運動的，所以不可能存在比絕對零度更低的溫度"。從意思上考慮應為"不可能的"，答案為B。
59 B 從詞意來考慮，選項 A為"燃燒";B為"冷卻";C為"吹";D為"切、割"。本句的意思是"兩位科學家將氣體冷卻到接近絕對零度"。答案為 B。
60 D 下文有提示，科學家 Satyendra Nath Bose 做了有關光子的理論研究。A 為"發(fā)明";
B 為"實驗";C 為"紙張、論文";D 為"理論"。答案為 D。
61 C 從詞意上考察。A為"強迫";B 為"乞求";C為"說服";D 為"命令"。本句的 意思是"因為 Bose 難以說服其他科學家相信他的理論，所以他就聯(lián)系了愛因斯坦"。答案為 C。
62 B 根據(jù)上下文判斷可以排除選項 C 和D。will 可用來表示"在一定的情況下通常會……'，又因為本句主句的時態(tài)為一般過去式，所以從句中的助動詞使用過去式 would。 本題答案為B
63 C 句中的 even 是對比較級的修飾，所以本題答案為 C，表達的意思是"甚至更準確"。
64 A 本句要表達的意思是"這些鐘準確到每 6 百萬年才差一秒鐘"，所以應該選擇every，表達"每一"，其與 each 的區(qū)別是 every帶有頻率的含義，而 each 沒有這種意思。
65 D 本句要表達的意思是"在長距離的太空旅行時，我們更需要準確的時間以判斷準確的距離"。只有選項 D"旅行"最合適。選項 A 為"站";B 為"工藝";選項 C 為"年齡、時代"。
