下面的材料從四個(gè)方面對(duì)二胡作了介紹，請(qǐng)篩選信息，保留各方面的主要內(nèi)容，壓縮成一段文字，不超過(guò)60個(gè)字。

　 二胡是中國(guó)的一種很奇妙的樂(lè)器，是胡琴的一種，比京胡大，也叫南胡。二胡的構(gòu)造很簡(jiǎn)單：由一根長(zhǎng)約80厘米的細(xì)細(xì)的木制琴桿、內(nèi)外兩根琴弦、琴桿下端的蒙著蟒皮或蛇皮的琴筒構(gòu)成，琴筒呈茶杯形，用木或竹制成，蟒皮或蛇皮是制作二胡的重要材料；用馬尾做的琴弓演奏，這與小提琴同樣用馬尾做琴弓是一樣的。二胡聲音低沉圓潤(rùn)，聽(tīng)起來(lái)略帶憂傷，常用來(lái)表達(dá)比較深沉的情感。二胡產(chǎn)生的歷史悠久，又比較容易學(xué)習(xí)，因此是深受中華民族喜愛(ài)的樂(lè)器，是中國(guó)民間普及率比較高的樂(lè)器。

解析：首先利用公式，確定主干句。二胡是一種樂(lè)器，“樂(lè)器”就是“二胡”的屬性。根據(jù)題干“從四個(gè)方面對(duì)二胡作了介紹”，可以提煉出“二胡”的另外三個(gè)特征：①二胡的構(gòu)造。②演出的材料及效果。③深受中華民族喜愛(ài)。然后嵌入公式，組成連貫的語(yǔ)句表達(dá)出來(lái)。

The Haitian tsunami gave scientists a chance to find out how well vital and potentially life-saving warning systems were working.

　 Noaa’s Pacific Marine Environmental Laboratory has developed a warning system that picks up signals of tsunamis directly from the sea-floor.

　 It is called Dart-the-Deep-ocean Assessment and Reporting of Tsunamis. If seismometers(地震儀) detect an earthquake, the Dart buoys（浮標(biāo)） will determine what is happening to sea levels, and whether a big wave might be on the way. This information is then sent via satellite to a central location which can organize an alarm. Within 50 minutes of the Haiti earthquake, this system was able to issue an alarm to other countries in the Caribbean to say that a small tsunami had been caused to start, and that was unlikely to affect them.

　 Dr Bernard said, “The first 30 minutes following the earthquake, we have to rely on education.” The critical aspects of this are: do you feel the earthquake; do you see the ocean draw down; and do you hear that loud roar? If so, you should run for higher ground.

　 “But after the first few minutes, it’s crucial that we have the technology—the measurements to avoid unnecessary evacuation(疏散撤離) and tell people when it is safe to return.” Right now, there are 50 of these Dart buoys all over the globe—four of which are in the Caribbean.

Dr Bernard says that, with 75 to 100 buoys worldwide, this system could provide global tsunami warnings within one hour.

“That’s for everywhere we know that tsunamis have happened. If we wanted to go to half an hour detection, we could probably double or multiply by four times that number,” he said.

　 “In some countries, including Haiti, there may not be enough resources to support a specific tsunami warning centre for something that happens so infrequently.”

　 He said that this system was relatively inexpensive to fix and operate.

　 “To get it down to an hour for everywhere affected would cost $50m initial investment and then 10% of that to maintain it,” he said.

　 “That’s not a terribly expensive system considering the potential savings of lives.”
