问题 Despite much educated conjecture, there remains no proven relationship between sunspot cycles and the earth’s weather.

选项 A、argument
B、confusion
C、speculation
D、disagreement

答案 C

解析 A选项argument意为“讨论,论据”;B选项confusion意为“混乱,混淆”;C选项speculation意为“思考,推测”;D选项disagreement意为“分歧,异议”。conjecture在这里是名词,意为“推测,猜测”。如果不认识这个词,可根据本句的直接语境no proven relationship来判断,既然二者的关系没有被证实,那conjecture只能是猜测,因此,C选项正确。本句大意为:尽管有大量基于经验的推测,但仍然没有证据证实太阳黑子周期与地球天气之间的关系。
