文字稿

Rogue waves can reach more than 30 metres high and at their worst can sink ships and sweep people out to sea.

“超級(jí)巨浪” 最高可達(dá) 30 多米，最猛烈的海浪可擊沉船只、把船員卷入海中。

To better understand how and when they might strike, scientists looked at 20 years of data collected along the west coast of America. Over this period, the frequency of these waves decreased slightly. But when they did appear, they were growing in size.

為深入了解它們突然出現(xiàn)的原理和時(shí)間，科學(xué)家們對(duì)從美國(guó)西海岸采集到的 20 年來(lái)的數(shù)據(jù)進(jìn)行了研究。在此期間，這類(lèi)海浪出現(xiàn)的頻率略有下降。但每次出現(xiàn)時(shí)，波浪的大小在逐漸增長(zhǎng)。

This was especially marked during the winter, where the waves intensified, increasing in height and occurring more often in calmer seas. These trends may be local to this area but the researchers now want to find out what’s driving these variations and to see how they're related to climate change.

這一現(xiàn)象在冬天尤為明顯：海浪的威力加強(qiáng)、高度上升，在更平靜的海況中出現(xiàn)的頻次也有所增加。上述趨勢(shì)可能只是該地區(qū)的局部現(xiàn)象，但現(xiàn)在研究人員們想找出推動(dòng)這些變化的原因，并弄清超級(jí)巨浪與氣候變化之間的聯(lián)系。

The waves pose a serious risk for the global shipping industry and scientists say more data is now needed from around the rest of the world to help predict when and where these waves could strike.

這類(lèi)海浪對(duì)全球海運(yùn)行業(yè)構(gòu)成嚴(yán)重的威脅，科學(xué)家們表示，現(xiàn)在他們需要世界其它地區(qū)提供更多數(shù)據(jù)，以幫助預(yù)測(cè)巨浪侵襲的時(shí)間及地點(diǎn)。

2. 閱讀理解：請(qǐng)?jiān)谧x完上文后，回答下列問(wèn)題 。

1. True or false? Although rogue waves are growing in size, they don’t happen quite as often.

2. Which part of the world did this research take place in?

3. How much do scientists think climate change is affecting the size and intensity of rogue waves in the winter?

4. What could help scientists work out where future rogue waves might strike?

3. 答案

1. True or false? Although rogue waves are growing in size, they don’t happen quite as often.
True. Data collected over 20 years found the frequency of rogue waves decreased slightly. But when they did appear, they were growing in size.

2. Which part of the world did this research take place in?
Scientists looked at 20 years of data collected along the west coast of America.

3. How much do scientists think climate change is affecting the size and intensity of rogue waves in the winter?
Scientists don’t know yet. Researchers now want to find out what’s causing these variations and to see how they're related to climate change.

4. What could help scientists work out where future rogue waves might strike?
Scientists want to collect more data from around the rest of the world to help predict when and where these waves could strike.
