【题目】A

Every February "Oscar fever" hits the entertainment community and film fans around the world, with the annual Academy Awards presentation happening a month later, when hundreds of millions of cinema lovers glue themselves to their television sets to learn who will receive the golden statuettes(小雕像).

The Academy Awards or Oscars is an annual American awards ceremony hosted by the Academy of Motion Picture Arts and Sciences(AMPAS) to recognize excellence in cinematic achievements in the United States film industry. First presented in 1929, the awards are among the film industry’s most desired prizes.

The AMPAS maintains a voting membership of 5,783 until 2012 and academy membership is divided into different branches. For most categories, members from each of the branches vote to determine the nominees(被提名的人) only in their respective categories. In the special case of Best Picture, all voting members have the right to select the nominees. In all major categories, each member votes for up to five nominees (ten for Best Picture). From among these nominees, all academy members select the winners by secret voting.

Since the earliest years, interest in the Academy Awards has run high. The awards ceremony was first broadcast on radio in 1930 and has had broadcast coverage ever since and televised for the first time in 1953. It is now seen live in more than 200 countries and can be streamed live online.

How the Oscar received its nickname is not clear. A popular, but unsupported story goes that the name caught on after the Academy’s Executive Director Margaret Herrick said that the statuette resembled her Uncle Oscar. Thus, the journalists and Academy staff started to refer to it by this name. Officially, the name Oscar has been used since 1939.

【1】What does Oscar fever indicate?

A.A medical condition where one feels sick.

B. People’s seeking Oscars blindly.
