Question

    As a Hollywood film star in the 1930s and 1940s, Hedy Lamarr at one point was called "the most beautiful woman in the world." What she was less known for was her scientific intellect.

Lamarr had a natural curiosity about the world around her. As young as age 5, she would spend time taking apart and rebuilding her music box to understand how it worked. But her technical mind was overshadowed by her looks-at 16, she got her  first film role and quickly became an international icon.

As her acting career continued to take off during World War II, Lamarr became restless, feeling that she should do more to contribute to the Allies' war efforts. Together with her friend Antheil, Lamarr came up with a groundbreaking new form of wireless communication known as spread spectrum(光谱).The concept was to create a wireless signal that could hop from frequency to frequency, making it impossible to track or jam.They received a patent for their technology in 1942, but the military refused to implement(实施) it in their war effort.

The technology sat unused for years, until one day the military revived it in the 1960s and the system "spread like wildfire."It became the backbone of Bluetooth, Wi-Fi, GPS and a range of wireless communication mechanisms we rely on today.By the time the technology was implemented, Lamarr's patent had been due, and she never received a single payment for her revolutionary invention.

Hedy Lamarr played the role she was expected to play in Hollywood — a beautiful object to admire on the big screen.If she yielded to society's expectations in other ways, communication as we know it could look completely different today.

1.

细节理解题。根据文章第一段As a Hollywood film star in the 1930s and 1940s, Hedy Lamarr at one point was called "the most beautiful woman in the world." What she was less known for was her scientific intellect. 作为20世纪30年代和40年代的好莱坞电影明星，Hedy Lamarr曾一度被称为“世界上最美丽的女人”。她较少为人所知的是她的科学才智。由此可知她既漂亮又有科学才智。故选C。

2.

细节理解题。根据文章第三段第一句As her acting career continued to take off during World War II, Lamarr became restless, feeling that she should do more to contribute to the Allies' war efforts. 二战期间，随着她的演艺事业继续腾飞，Lamarr变得焦躁不安，觉得自己应该为盟军的战争做更多的贡献。由此可知她后来发明光谱是因为想要为盟军做贡献，故选B。

3.

细节理解题。根据文章第四段第一句The technology sat unused for years, until one day the military revived it in the 1960s and the system "spread like wildfire." 这项技术闲置了很多年，直到20世纪60年代军方重新使用它，该系统“像野火一样蔓延”。由此可知该技术在20世纪60年代才得到使用，故选C。

4.

推理判断题。根据文章的主要内容：讲述一位著名的好莱坞明星Hedy Lamarr，但却很少有人知道她的科学才智，她用她的科学才智在二战中和她的朋友发明了一项专利，最终在20世纪60年代得到广泛使用。由此可推断作者想让人们记住Hedy Lamarr不仅仅是一位漂亮的明星，更是一个伟大的发明家，故选A。
