问题:

克鲁彭金说:“一直以来,我们都不缺能量,缺的是能将其转化为电能的技术和设备。”目前使用较多的能量捕获技术,大都用在如风力或太阳能发电这样的大功率发电装置或如计算器、手表、传感器这样的小型装置上,而处于两者中间的、满足便携式电子设备用电需求的能量捕获装置却几乎是一片空白。虽然太阳能光电转化技术在便携设备中被广泛采用.但直接的阳光照射并不如人体运动那样易得、方便,因此。这项能将人体机械能转化为电能的技术将是一项极有意义的尝试。

这段文字意在说明:()

A.一直以来我们缺的是将能量转化为电能的技术和设备 

B.太阳能光电转化技术在便携设备中已被广泛采用 

C.能量捕获技术将有可能用在处于大型与小型装置中间的设备上 

D.将人体机械能转化为电能的技术将是一项有意义的尝试

Arthur Miller (1915-2005) is universally recognized as one of the greatest dramatists of the 20th century. Miller’s father had moved to the USA from Austria-Hungary, drawn like so many other by the "Great American Dream." However, he experienced severe financial hardship when his family business was ruined in the Great Depression of the early 1930s.

Miller’s most famous play, Death of a Salesman, is a powerful attack on the American system with its aggressive way of doing business and its insistence on money and social status as indicators of worth. In Willy Lowman, the hero of the play, we see a man who has got into double with his worth. Willy is "burnt out" and in the cruel world of business there is no room for sentiment: if he can’t do the work, then he is no good to-his employer, the Wagner Company, and he must go. Willy is painfully aware of this, and at loss as to what to do with his lack of success. He refuses to face the fact that he has failed and kills himself in the end.

When it was first staged in 1949, the play was greeted with enthusiastic reviews, and it won the Tony Award for Best Play, the New York Drama Critics’ Circle Award, and the Pulitzer Prize for Drama. It was the first play to win all three of these major awards.

Miller died of hear failure at his home in Roxbury, Connecticut, on the evening of February 10, 2005, the 56th anniversary of the first performance of Death of a Salesman on Broadway.

Why did Arthur Miller’s father move to the USA()

A. He suffered from severe hunger in his home country.

B. He was attracted by the "Great American Dream".
