一项政府报告透露，美国核武器部队仍在使用七十年代时兴的计算机系统及软盘。以下是 Gary O'Donoghue 的报道。
You may have thought the floppy disk was now an historical artefact. But it turns out it's alive and well within the US Defence Department and used to store data in the system that communicates with the different parts of America's nuclear deterrent.
The 1970s technology is so limited that you need about three million of them to approach the storage capacity of a $10 USB memory stick.
But the Pentagon isn't alone. US social security systems are written in a computer language dating from the late 1950s which fewer and fewer people are familiar with.
On the floppy disks, the Pentagon says they'll be gone by the end of next year, though the 40-year-old computers that use them may take a little longer to reach the museum.

答案
1. When the floppy disk becomes a historical artefact, where should it be kept?
In a museum.
2. What can hold almost the same amount of data as a $10 USB memory stick?
Three million 70s floppy disks.
3. True or false? US social security systems are written in a well-known computer language.
False. The computer language dates from the 50s and fewer and fewer people are familiar with it.
4. Why are there hyphens in the expression "40-year-old computers"?
Because here age is an adjective and you use hyphens when you put ages and numbers before a noun.
