Australia’s Great Barrier Reef will lose most of its coral cover by 2050 and, at worst, the world’s largest coral system could collapse by 2100 because of global warming, a study recently said.

     The study by Queensland University’s Center for Marine Studies, commissioned (委托) by the Worldwide Fund for Nature, said that the destruction of coral on the Great Barrier Reef was unavoidable due to global warming, regardless of what actions were taken now. “Under the worst-case scenario, coral populations will collapse by 2100 and the reestablishment of coral reefs will be highly unlikely over the following 200-500 years,” said the report entitled “Implications (可能的影响) of Climate Change for Australia’s Great Barrier Reef.”

     The Great Barrier Reef is the world’s largest living reef formation stretching 2,000 km north to south along Australia’s northeast coast. “Only if global average temperature change is kept to below two degrees Celsius can the Reef have any change of recovering from the predicted damage,” the report said. Coral has a narrow comfort zone and is highly stressed by a temperature rise of less than one degree Celsius. Water temperature rises of less than one degree coincided (同时发生) with the world’s worst recorded coral bleaching (颜色变淡) period in 1988. The warmer water forces out the algae (海藻) that give coral its color and, if all are lost, the coral dies and the reef will die out. In 1988, 16 percent of the world’s coral died, with 46 percent of the Indian Ocean coral destroyed.

     Scientists express water temperatures to rise this century by between two and six degrees Celsius. “There is little to no evidence that corals can adapt fast enough to match even the lower  temperature rise,” said the report. Over-fishing and pollution from coastal farms were also contributing to the destruction of coral on the Great Barrier Reef.

     The Great Barrier Reef supports huge fishing and tourism industries. Even under favorable conditions tourists would only be able to experience real corals in reef “theme parks”.

The underlined word “scenario” in Paragraph 2 probably means         .

Whether they’re project documents, trade journals, blogs, business books or ebooks, most of us read regularly as part of our jobs, and to develop our skills and knowledge.

But do you ever read what should be a useful document, yet fail to gain any helpful information from it? Or, re-read something several times to get a full understanding of the content? If so, look at the following strategies (策略) that will help you read more effectively.

●Think About What You Want to Know

Before you start reading anything, ask yourself why you’re reading it. Are you reading with a purpose, or just for pleasure? What do you want to know after you’ve read it? Once you know your purpose, you can examine the resource (资源) to see whether it’s going to help you.

Ask yourself whether the resource meets your needs, and try to work out if it will give you the right amount of knowledge. If you think that the resource isn’t consummate, don’t waste time reading it.

●Know How Deeply to Study the Material

Where you only need the shallowest knowledge of a subject, you can skim material. Here you read only chapter headings, introductions, and summaries.

If you need a moderate (中等的) level of information on a subject, then you can scan the text. This is when you read the chapter introductions and summaries in detail. You can then speed read the contents of the chapters, picking out and understanding key words and concepts.

Only when you need full knowledge of a subject is it worth studying the text in detail (细节). Here it’s best to skim the material first to get an overview of the subject. This gives you an understanding of its structure, into which you can then fit the detail gained from a full reading of the material.

1.Why should we know our purpose before reading?

A.Because we can develop our skills and knowledge.

B.Because we can get a full understanding of the content.

C.Because we can avoid re-reading something several times.

D.Because we can check it out whether the material will be helpful.

2.What does the underlined word “consummate” in the 5th paragraph mean?

A.Legal.

B.Natural.

C.Perfect.

D.Formal.

3. According to the depth to study the material, how many reading strategies are mentioned?

A.2.

B.3.

C.4.

D.5.

4.The best title for this passage should be ______.

A.Reading Strategies

B.Think About What You Want to Know

C.Know How Deeply to Study the Material

D.How to Develop our Skills and Knowledge
