Question

【題目】 One of Australia’s most famous natural gifts, the Great Barrier Reef is blessed with the breathtaking beauty of the world’s largest coral reef. The reef contains a large variety of life and over 3000 reef systems and hundreds of islands with some of the world’s most beautiful beaches. Because of its natural beauty, the Great Barrier Reef has become one of the world’s most sought after tourist attractions.

However, for the past few years, the news about corals has been discouraging. Currently, the reef is threatened by climate change, tourism, water pollution, and overfishing. Agricultural fertilizer(肥料) runoff from Australian farms also has caused the widespread growth of sea-plants, which absorb most of the nutrients(養(yǎng)分) and leave little remaining for the living coral reef and the animals that live in it. “What has changed is the increasing importance of climate change as a greater threat than the others,” says David Wachenfeld, a scientist of the Great Barrier Reef Marine Park Authority. Coral reefs are extremely sensitive(敏感的) to warming ocean temperatures.

In a report on April 28, the Australian government said it set aside $500 million to help protect corals. The money will be spent on reducing water pollution from agriculture, fighting coral-killing starfish, reef monitoring, and research on climate influence.

Though the Australian investment is welcome, it will at best only delay coral deaths. It’s too little, too late, as a leading coral-scientist Terry Hughes of James Cook University put it. The only way to save corals over the long term is to slow down climate change. That process will require all countries to work together to find the most effective way of cutting emissions (排放) of greenhouse gases.

The most recent emissions figures, however, show that the world is failing at that task. The year 2018 has seen an increase in global emissions. This week in Bonn, Germany, countries are meeting to discuss how to keep their word in the Paris climate agreement. Let’s hope they hear about the silent death of the world’s corals.

【1】Why does the author write the text?

A.To introduce the Great Barrier Reef.

B.To show the result of climate change.

C.To offer ways of protecting the Great Barrier Reef.

D.To tell us the serious situation of the Great Barrier Reef.

【2】What can be inferred from Paragraph 2?

A.Sea-plants help to protect the coral reefs.

B.Water temperature has little to do with the coral reefs.

C.Climate change is the main reason for coral reefs’ death.

D.Agricultural fertilizer provides nutrients for coral reefs.

【3】According to Terry Hughes, the Australian investment in protecting the coral reefs was _______.

A.timelyB.unsatisfying

C.effectiveD.useless

【4】How can we protect the Great Barrier Reef effectively in the long run?

A.By reducing the emissions of greenhouse gases.

B.By cutting down the number of tourists.

C.By setting more strict rules on overfishing.

D.By investing more in climate research.

Answer 1

【答案】

【1】D

【2】C

【3】B

【4】A

【解析】

這是一篇說明文。目前，大堡礁正受到氣候變化、旅游業(yè)、水污染和過度捕撈的威脅。文章主要內(nèi)容為描述大堡礁面臨各方面的影響，正在不斷死亡的嚴峻情況。而澳大利亞政府投資最多只能延緩珊瑚的死亡，從長遠來看，拯救珊瑚的唯一方法是減緩氣候變化。

【1】推理判斷題。根據(jù)第二段中Currently, the reef is threatened by climate change, tourism, water pollution, and overfishing.可知目前，大堡礁正受到氣候變化、旅游業(yè)、水污染和過度捕撈的威脅。結(jié)合文章主要內(nèi)容為描述大堡礁面臨各方面的影響，正在不斷死亡的嚴峻情況。由此可推知，作者寫這篇文章是為了告訴我們大堡礁面臨的嚴峻情況。故選D。

【2】推理判斷題。根據(jù)第二段中“What has changed is the increasing importance of climate change as a greater threat than the others,” says David Wachenfeld, a scientist of the Great Barrier Reef Marine Park Authority. Coral reefs are extremely sensitive to warming ocean temperatures.可知大堡礁海洋公園管理局的科學(xué)家David Wachenfeld表示:“氣候變化的重要性越來越大，它是一個比其他因素更大的威脅�！� 珊瑚礁對海洋溫度的升高極為敏感。由此可推知，氣候變化是珊瑚礁死亡的主要原因。故選C。

【3】推理判斷題。根據(jù)第四段中It’s too little, too late, as a leading coral-scientist Terry Hughes of James Cook University put it.可知正如James Cook大學(xué)的首席珊瑚科學(xué)家Terry Hughes所說，這太少了，也太晚了。由此可知，根據(jù)Terry Hughes的說法，澳大利亞在保護珊瑚礁上的投資并不令人滿意。故選B。

【4】推理判斷題。根據(jù)倒數(shù)第二段中The only way to save corals over the long term is to slow down climate change. That process will require all countries to work together to find the most effective way of cutting emissions of greenhouse gases.可知從長遠來看，拯救珊瑚的唯一方法是減緩氣候變化。這一進程將要求所有國家共同努力，找到削減溫室氣體排放的最有效方法。由此可知，從長遠來看，可以通過減少溫室氣體的排放來有效地保護大堡礁。故選A。
