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(dá)每小時(shí)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(dāng)然，飛機(jī)的速度可以突破超音速，但是汽車呢?1997年內(nèi)華達(dá)州黑巖沙漠一輛汽車做到了。英國司機(jī)開了一輛噴氣發(fā)動(dòng)機(jī)汽車，車速達(dá)到763英里每小時(shí)，仍是現(xiàn)在的吉尼斯世界紀(jì)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(diǎn)慢，至少相比，工程師希望能達(dá)到這樣。這輛車叫做尋血獵犬，估計(jì)成本達(dá)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(píng)人士稱這就是浪費(fèi)錢，但是該項(xiàng)目的負(fù)責(zé)人稱，他希望該項(xiàng)目能為未來英國發(fā)動(dòng)機(jī)的發(fā)展提供靈感。
