Passage One
短文一
Birds are famous for carrying things around.
鳥(niǎo)類(lèi)以搬運(yùn)東西而聞名。
Some, like homing pigeons, can be trained to deliver messages and packages.
有些像信鴿一樣，可以接受培訓(xùn)以傳遞消息和包裹。
Other birds unknowingly carry seeds that cling to them for the ride.
其它鳥(niǎo)類(lèi)在不知不覺(jué)中攜帶了粘附著它們的種子。
Canadian scientists have found a worrisome, new example of the power that birds have to spread stuff around.
加拿大科學(xué)家發(fā)現(xiàn)了一個(gè)令人擔(dān)憂(yōu)的事實(shí)，即鳥(niǎo)類(lèi)所擁有的傳播的力量的新例子。
Way up north in the Canadian Arctic, seabirds are picking up dangerous chemicals in the ocean and delivering them to ponds near where the birds live.
在加拿大北極的北部，海鳥(niǎo)正在海洋中拾起危險(xiǎn)化學(xué)品，并將其運(yùn)送到靠近鳥(niǎo)類(lèi)生活地的池塘。
Some 10,000 pairs of the birds, called fulmars, a kind of Arctic seabird, make their nests on Devon Island, north of the Arctic Circle.
北極圈北部的德文島上有一萬(wàn)只鳥(niǎo)在此筑巢，它們被稱(chēng)為管鼻藿，一種北極海鳥(niǎo)。
The fulmars travel some 400 kilometers over the sea to find food.
這些管鼻藿在海上穿越約四百公里去尋找食物。
When they return home, their droppings end up all around their nesting sites, including in nearby ponds.
當(dāng)他們回家時(shí)，他們的糞便會(huì)圍繞著他們的筑巢地點(diǎn)，包括附近的池塘。
Previously, scientists noticed pollutants arriving in the Arctic with the wind.
以前，科學(xué)家注意到有隨著風(fēng)抵達(dá)北極的污染物。
Salmon also carry dangerous chemicals as the fish migrate between rivers and the sea.
隨著魚(yú)類(lèi)在海洋之間的遷徙，三文魚(yú)也會(huì)攜帶危險(xiǎn)化學(xué)品。
The bodies of fish and other meat-eaters can build up high levels of the chemicals.
魚(yú)類(lèi)和其他肉食者的尸體可以積累高含量的化學(xué)物質(zhì)。
To test the polluting power of fulmars, researchers collected samples of deposit from 11 ponds on Devon Island.
為了測(cè)試污染物的污染力，研究人員從德文島的11個(gè)池塘收集了沉積物樣本。
In ponds closest to the colony, the results showed there were far more pollutants than in ponds less affected by the birds.
在最靠近棲息地的池塘中，結(jié)果顯示污染物遠(yuǎn)遠(yuǎn)高于不受鳥(niǎo)類(lèi)影響的池塘。
The pollutants in the ponds appear to come from fish that fulmars eat when they're out on the ocean.
池塘中的污染物似乎來(lái)自管鼻藿在海洋里吃的魚(yú)類(lèi)。
People who live, hunt, or fish near bird colonies need to be careful, the researchers say.
研究人員說(shuō)，在禽鳥(niǎo)群附近生活，狩獵或捕魚(yú)的人需要小心。
The birds don't mean to cause harm, but the chemicals they carry can cause major problems.
鳥(niǎo)類(lèi)不意味著會(huì)造成傷害，但它們攜帶的化學(xué)物質(zhì)可能會(huì)導(dǎo)致重大問(wèn)題。
Questions 9 to 12 are based on the passage you have just heard.
問(wèn)題9到12基于你剛剛聽(tīng)到的段落。
Question 9. What have Canadian scientists found about some seabirds?
問(wèn)題9.加拿大科學(xué)家關(guān)于海鳥(niǎo)有什么發(fā)現(xiàn)？
Question 10. What does the speaker say about the seabirds called fulmars?
問(wèn)題10.說(shuō)話(huà)者說(shuō)了關(guān)于管鼻藿的什么？
Question 11. What did scientists previously notice about pollutants in the Arctic?
問(wèn)題11.科學(xué)家之前發(fā)現(xiàn)了北極圈污染物的什么實(shí)事？
Question 12. What does the speaker warn about at the end of the talk?
問(wèn)題12.說(shuō)話(huà)者在講話(huà)的最后做出了什么警告？
