现代大爆炸理论认为：天然元素源于氢氦等发生的原子核的融合反应。这于一百多年前，普鲁特运用思辨性推测作出“氢是所有元素之母”的预言，恰好“一致”。下列说法正确的是
A．科学研究中若能以思辨性推测为核心，就能加快科学的进程
B．普鲁特“既然氢最轻，它就是其他一切元素之母”的推理是符合逻辑的
C．“一致”是巧合，普鲁特的预言没有科学事实和理论支撑，只是一种猜测
D．“现代大爆炸理论”是解释宇宙诞生的唯一正确的理论
答案：C
题目分析：思辨性是脱离社会实践，在书斋中，通过抽象的思考、推理、论证得出的结论，所以不能加快科学的进程，A项错误；普鲁特是通过思辨性推测出来的推理不符合逻辑，B项错误；“现代大爆炸理论”是解释宇宙诞生的唯一正确的理论不上唯一的正确理论，D项错误。答案选C。
点评：本题非常基础简单。
Two brothers worked together on a farm. One was married and had a large 41 .The other had no wife yet. Although they lived in different houses, they shared everything they got from their farm. One day, the single brother said to himself, “It’s not 42 that we share all the rice. I’m 43 and I need less than my brother.” So, every night he took a bag of rice from his store-room and 44 across the field 45 their houses, putting it into his brother’s store-room. At the same time, the married brother thought, “It’s not fair to share all the rice. I’m married and I have my wife and children to 46 me when I am 47 . However, my brother has no one to take care of his 48 .” So, each night he also took a bag of rice and put it into his brother’s store-room. Several months passed by. They found 49 strange that their rice never became less. Then, one dark night the two brothers ran into each other. Slowly they began to understand what was happening. Their bags fell onto the ground and tears 50 their eyes at once.
