问题 多项选择题

下列关于美元汇率变化对商品期货市场影响的叙述,正确的有()。

 

A.一般而言,美元和商品价格呈负相关性

B.美元汇率变化对不同商品价格影响有较大差异

C.美元走势和商品价格并不完全负相关,阶段性也会出现齐涨共跌

D.美元贬值会推动以其他国际货币标价的商品期货价格上涨

答案

参考答案:A, B, C

解析:国际市场上大部分商品在期货交易中都以美元标价,若美元贬值,则以美元标值的商品期货价格上涨。美元贬值意味着其他国际货币的相对升值,如日元和欧元。在以日元和欧元标价的商品期货市场上,伴随着本币不断升值,商品期货价格涨势受到了抑制。故D选项表述有误。

单项选择题

People are indulging in an illusion whenever they find themselves explaining at a cocktail(鸡尾酒) party, say, that they are "in computers," or "in telecommunications," or "in electronic funds transfer". The implication is that they are part of the high-tech world. Just between us, they usually aren’t. The researchers who made fundamental breakthroughs in those areas are in a high-tech business. The rest of us are()of their work. We use computers and other new technology components to develop our products or to organize our affairs. Because we go about this work in teams and projects and other tightly knit working groups(紧密联系在一起的工作小组), we are mostly in the human communication business. Our successes stem from good human interactions by all participants in the effort, and our failures stem from poor human interactions. The main reason we tend to focus on the()rather than the human side of the work is not because it’s more(), but because it’s easier to do. Getting the new disk drive installed is positively trivial compared to figuring out why Horace is in a blue funk(恐惧) or why Susan is dissatisfied with the company after only a few months. Human interactions are complicated and never very crisp(干脆的,干净利落的) and clean in their effects, but they matter more than any other aspect of the work. If you find yourself concentrating on the()rather than the(), you’re like the vaudeville character(杂耍人物) who loses his keys on a dark street and looks for them on the adjacent street because, as he explains, "The light is better there!".

If you find yourself concentrating on the ()

A.technology

B.sociology

C.physiology

D.astronomy
