下面一起來(lái)了解一下Ocean Biodiversity聽(tīng)力文章的答案解析：

Question 31：

答案：conservation

定位原文：scripts:

The hotspots are significant because they allow us to locate key areas for focusing efforts at conservation.

解題思路：第一個(gè)設(shè)空處是關(guān)于Biodiversity hotspots的，預(yù)讀題目時(shí)候locating targets這個(gè)信息非常重要，locate key areas這個(gè)表達(dá)在聽(tīng)力原文中重現(xiàn)，后面的focusing efforts at conservation就是答案關(guān)鍵。

Question 32：

答案：food/foods

定位原文：scripts:

The main thing he’d expected to find was that they had very high concentrations of food,but to his surprise that was only true for four of hotspots–remaining hotspot was quite badly off in that regard.

解題思路：這個(gè)部分設(shè)空是關(guān)于Boris Worm這個(gè)人的研究，人名可以幫我們鎖定解題區(qū)域。設(shè)空處是三個(gè)關(guān)于ocean hotspots的三個(gè)發(fā)現(xiàn)，expected to find就是答案出現(xiàn)的地方了。此題比較簡(jiǎn)單。

Question 33：

答案：surface

定位原文：scripts:

The water at the surface of the ocean had relatively high temperatures,even when it was cool at greater depths.

解題思路：上文的空填出來(lái)之后，后面緊接著就是33題的答案。

Question 34：

答案：oxygen/O2

定位原文：scripts:

Because the also found that the water needed to have enough oxygen in it.

解題思路：和32、33題一樣，可以確認(rèn)答案出現(xiàn)的區(qū)域。預(yù)讀題目，可以知道問(wèn)的是水里有充足的什么，have enough后面就是答案。

Question 35：

答案：mammals

定位原文：scripts:

What she was interested in was marine mammals,things like seals.

解題思路：35題問(wèn)的是Lisa Ballance這個(gè)人的研究。挖空處問(wèn)的是她的研究?jī)?nèi)容，聽(tīng)力原文用“was interested in”來(lái)鎖定答案。

Question 36：

答案：ice

定位原文：scripts:

One thing they found there which stunned other researchers was that there were large numbers of species which live below the ice.

解題思路：36題問(wèn)的是發(fā)現(xiàn)new ocean species的其中一個(gè)居住地，原文的below the ice就是答案，所以空處就是填寫(xiě)ice。

Question 37：

答案：decline/declining/decrease

定位原文：scripts:

Thirdly,they calculate the rate at which the decline of the species is happening.

解題思路：37和38題都屬于Global Marine Species Assessment這個(gè)組織，37題屬于list endangered ocean species要考慮的因素;38題是問(wèn)這個(gè)組織成立的目的。組織的名字幫助定位答題區(qū)域。Thirdly they calculate the rate出現(xiàn)，37題答案就出來(lái)了。

Question 38：

答案：map

定位原文：scripts:

For each one they assess,they use the data they collect on that species to produce a map showing its distribution.

解題思路：部分同上，distribution出現(xiàn)在原文中，produce a map showing its distribution和題目make a distribution map是同義表達(dá)。

Question 39：

答案：migration

定位原文：scripts:

We need to create corridors for migration.

解題思路：為了保持海洋多樣性的一些建議，corridor是解題關(guān)鍵，for表示目的，可以得知migration是答案。

Question 40：

答案：consumption

定位原文：scripts:

So that only the fish wanted for consumption were caught.

解題思路：so that表示目的，同義表達(dá)for the purpose of，定位后此題答案比較容易得出。
