CNN News: 尋血獵犬

On an average day, sound waves travel at about 762 miles per hour. So, option (d) is supersonic. That`s your answer and that`s your shoutout.

平均每天，聲波的速度可達每小時約762英里。所以，選擇(d)是超音速。這就是你的回答和你的shoutout。

AZUZ: Of course, jets can break the speed of sound, but can a car? One did in 1997 in Nevada`s Black Rock Desert. A British driver took a jet engine vehicle to 763 miles per hour, a Guinness World Record that still stands.

當然，飛機的速度可以突破超音速，但是汽車呢?1997年內華達州黑巖沙漠一輛汽車做到了。英國司機開了一輛噴氣發(fā)動機汽車，車速達到763英里每小時，仍是現(xiàn)在的吉尼斯世界紀錄。

It was supersonic and it`s kind of slow, at least when compared to what engineers hope what this will do. It`s called the Bloodhound Project, estimated cost, $62 million, paid for by sponsors and supporters.

這就是超音速，但是有點慢，至少相比，工程師希望能達到這樣。這輛車叫做尋血獵犬，估計成本達到620萬美元，由贊助者和支持者們出資。

Critics may say it`s a waste of money, but the project`s director says he hopes it will inspire Britain`s future engineers.

批評人士稱這就是浪費錢，但是該項目的負責人稱，他希望該項目能為未來英國發(fā)動機的發(fā)展提供靈感。
