1) a CAT scan: CAT come from Computed Axial Tomography. CAT scans take the idea of conventional X-Ray imaging to a new level. Instead of finding the outline of bones and organs, a CAT scan machine forms a full three-dimensional computer model of a patient's insides. Doctors can even examine the body one narrow slice at a time to pinpoint specific areas.
1）CAT 掃描：CAT是計算機控制軸向x線斷層攝影術的縮寫。CAT 掃描把我們平常的x光帶到了壹個新的階段。CAT 掃描儀在電腦上形成患者3d的立體內部模型，從而代替了x光的只是形成骨骼和器官的外形。醫生們甚至可以只檢查患者身體的壹小部分，然後確定身體中具體的位置。

3）9-1-1: The first use of 9-1-1 took place in Haleyville, Ala. in January 1968. The town had a population of approximately 4,500 and was serviced by the Alabama Telephone Company (ATC). The 9-1-1 number was intended to be an easy-to-remember, no-coin method of reaching the correct law enforcement, fire and EMS agencies. Congress had declared that 9-1-1 should be the national emergency number just weeks before and a man called Bill Frye, an ATC engineer, quickly made some changes to the company's small telephone system to accept 9-1-1 calls. A debate broke out about where 9-1-1 calls should be routed - to the police, fire department, or local hospital. Officials settled on the Haleyville police, and a red telephone. There was no ANI/ALI service with this first installation. The first 9-1-1 call from Haleyville was made by Alabama Speaker of the House Rankin Fite on February 16, 1968 to Tom Bevill, a U.S. Representative. Later, the two said they exchanged greetings, hung up and "had coffee and doughnuts."
3）9-1-1: 人們第壹次使用9-1-1是在黑利維爾（美國地名），在1968年的1月。整個城鎮的人口大約有4500人，亞拉巴馬（美國壹個州）電訊公司為他們服務。9-1-1這三個數字很好記，法律執行、消防、都可以打這個電話。會議決定9-1-1應該是國際急救電話。而壹個在ATC工作的叫Bill Frye的男人幾周後改變了公司壹些接通9-1-1的手機系統。壹場關於由誰該接通9-1-1的爭議也隨之開始- 是由警察、消防署、還是當地的醫院接聽。在第壹個就職地點沒有ANI或ALI服務。第壹個來自黑利維爾的9-1-1電話是壹個在House Rankin Fite的亞拉巴馬發言者在1968年2月16日打給壹位叫Tom Bevil的英國代表的。後來，他們說他們在電話裏互相問好，掛了電話，然後“吃了甜甜圈喝咖啡”。（這裏應該是沒事幹的意思）
