Question

【題目】

Australian Great Barrier Reef -- a great collection of thousands of smaller coral(珊瑚) reefs, is the world’s largest reef system. It is over 2,600 kilometers long. It goes from the northern tip of Queensland to the state’s southern city of Bundaberg -- was given World Heritage(世界遺產(chǎn)) status in 1981. The UN says it is the “most biodiverse” (物種最為多樣性)of all the World Heritage sites, and of “great scientific importance”.

The reef is home to many animals: fish, birds, turtles, sharks and even whales. Unfortunately, the reef that all these animals call home is in danger.

Climate (氣候) change, overfishing, Epical storms and water pollution are damaging (損害)the reef every year. Coral reef experts at Australian universities say that if we do nothing to stop it, the coral reef could be destroyed(摧毀)before the year 2030.

Everyday things like driving cars, using electricity and running a factory give out greenhouse gases into the air. These gases make Earth warmer and warmer. This is a problem for the Great Barrier Reef and other reefs around the world.

Coral is very fragile, and even a 2-degree increase in water temperature is enough to kill it, according to Ove Hoegh-Guldberg reef researcher at the University of Queensland, Australia. Therefore, if the water temperature doesn’t go down, the coral dies. But it’s not only the coral that’s in danger. One quarter of all sea life lives on coral reefs.

If air pollution is not slowed down or stopped, then the water will warm by at least 3 degrees in the next 20 years, according to reef experts in a report from University of Queensland. This would spell the end for the Great Barrier Reef and all its sea life.

【1】Which of the following can destroy the Great Barrier Reef?

a. sea animals b. global warming c. overfishing d. water pollution

A.abcB.acdC.bcd

【2】In the article, Ove Hoegh-Guldberg told us that ________.

A.the coral reef will be destroyed before 2030

B.rising water temperatures could kill the coral

C.other sea animals living in coral reefs are also in danger

【3】The underlined word “fragile” probably means ________.

A.珍貴的B.脆弱的C.纖細(xì)的

【4】Which of the following statements is NOT TRUE?

A.The world’s largest reef system is nearly 2,600 kilometers long.

B.There are fish, birds, turtles, sharks and even whales living on coral reefs.

C.According to the reef researcher’s opinion, coral may have been in danger now.

【5】The passage mainly tells us that ________.

A.coral can easily get used to changes

B.Australia’s Great Barrier Reef is in great danger

C.all sea animals will die along with the Great Barrier

Answer 1

【答案】

【1】C

【2】B

【3】B

【4】A

【5】B

【解析】

本文是一篇說明文。澳大利亞的大堡礁是世界上最大的珊瑚礁系統(tǒng)，但由于受到氣候變化、過度捕撈和水污染的影響，這里的珊瑚礁正面臨著危險。文章呼吁人們采取行動來保護(hù)這些珊瑚礁。

【1】細(xì)節(jié)理解題。根據(jù)“Climate (氣候) change, overfishing, Epical storms and water pollution are damaging (損害) the reef every year.” 每年的氣候變化，過度捕撈，風(fēng)暴和水污染正在損害珊瑚礁�？芍�，四個選項中大氣變暖，過度捕撈和水污染可以摧毀大堡礁。故選C。

【2】細(xì)節(jié)理解題。根據(jù)“Coral is very fragile, and even a 2-degree increase in water temperature is enough to kill it,” 珊瑚非常脆弱，水溫上升2度就足以殺死它，可知，水溫升高可能會殺死珊瑚。故選B。

【3】詞義猜測題。根據(jù)“even a 2-degree increase in water temperature is enough to kill it” 即使水溫升高2度也足以殺死它，可知，珊瑚很脆弱，所以fragile是脆弱的意思，故選B。

【4】正誤判斷題。根據(jù)“It is over 2,600 kilometers long” 它有2600多公里長，可知，A選項“世界上最大的珊瑚礁群有近2600公里長”是錯誤的；根據(jù)“The reef is home to many animals: fish, birds, turtles, sharks and even whales.” 珊瑚礁是許多動物的家園:魚，鳥，海龜，鯊魚，甚至鯨魚，可知B選項中“珊瑚礁上生活著魚類、鳥類、海龜、鯊魚甚至鯨魚”是正確的；根據(jù)“Therefore, if the water temperature doesn’t go down, the coral dies. But it’s not only the coral that’s in danger” 因此，如果水溫不下降，珊瑚就會死亡。但危險的不僅僅是珊瑚。可知，C選項中“根據(jù)珊瑚礁研究者的觀點(diǎn)，珊瑚現(xiàn)在可能處于危險之中”是正確的；綜上所述，故選A。

【5】主旨大意題。根據(jù)“But it’s not only the coral that’s in danger.”大堡礁處于危險中，及“This would spell the end for the Great Barrier Reef...”這將導(dǎo)致大堡礁的終結(jié)，可知，大堡礁正處于危險中，故選B。
