2015年职称英语考试理工类试题练习及答案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(颗粒)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 本句要表达的是两个对立的意思:离太阳越近,我们感到越热;离太阳越远,我们 感到越寒冷。从所给介词的含义来看,只有 away有"开"的意思。答案为C。

57 A 本段要表达的意思是 "温度取决于与太阳的距离",所以本句的空格应填写 location,表达"位置"这个概念。选项 B 是"教育";C 是"地位";D 是"知识"。答案只能为A 。

58 B 从意思上来考虑,选项 A 为"有趣的";选项 B 是"不可能的";选项 C 是 "合理的";D是"必要的"。文章要表达"我们被告知绝对零度之下原子是无法运动的,所以不可能存在比绝对零度更低的温度"。从意思上考虑应为"不可能的",答案为B。

59 B 从词意来考虑,选项 A为"燃烧";B为"冷却";C为"吹";D为"切、割"。本句的意思是"两位科学家将气体冷却到接近绝对零度"。答案为 B。

60 D 下文有提示,科学家 Satyendra Nath Bose 做了有关光子的理论研究。A 为"发明";

B 为"实验";C 为"纸张、论文";D 为"理论"。答案为 D。

61 C 从词意上考察。A为"强迫";B 为"乞求";C为"说服";D 为"命令"。本句的 意思是"因为 Bose 难以说服其他科学家相信他的理论,所以他就联系了爱因斯坦"。答案为 C。

62 B 根据上下文判断可以排除选项 C 和D。will 可用来表示"在一定的情况下通常会……',又因为本句主句的时态为一般过去式,所以从句中的助动词使用过去式 would。 本题答案为B

63 C 句中的 even 是对比较级的修饰,所以本题答案为 C,表达的意思是"甚至更准确"。

64 A 本句要表达的意思是"这些钟准确到每 6 百万年才差一秒钟",所以应该选择every,表达"每一",其与 each 的区别是 every带有频率的含义,而 each 没有这种意思。

65 D 本句要表达的意思是"在长距离的太空旅行时,我们更需要准确的时间以判断准确的距离"。只有选项 D"旅行"最合适。选项 A 为"站";B 为"工艺";选项 C 为"年龄、时代"。
