No longer in the pink
Corals are comeback creatures. As the world froze and melted and sea levels rose and fell over 30,000 years, Australia’s Great Barrier Reef, which is roughly the size of Italy, died and revived five times. But now, thanks to human activity, corals face the most complex condition they have yet had to deal with.
According to the Intergovernmental Panel on Climate change, a rise in global temperatures of 1.5oC could cause coral reefs to decline 70-90%. The planet is about 1oC hotter than in the 19th century and its seas are becoming warmer, stormier and more acidic. This is already affecting relations between corals and the single-celled algae (海藻), which give them their color. When waters become unusually warm, algae float away, leaving reefs a ghostly white. This “bleaching” is happening five times as often as it did in the 1970s. Meanwhile the changing chemistry of the oceans makes it harder for corals to form their structures.
If corals go, divers and marine biologists are not the only people who will miss them. Reefs take up only a percent of the sea floor, but support a quarter of the planet’s fish diversity. The fish that reefs shelter are especially valuable to their poorest human neighbors, many of whom depend on them as a source of protein. Roughly an eighth of the world’s population lives within 100km of a reef. Corals also protect 150,000km of shoreline in more than 100 countries and territories from the oceans buffeting, as well as generating billions of dollars in tourism revenue.
Coral systems must adapt if they are to survive. They need protection from local sources of harm. Their eco-systems suffer from waste from farms, building sites and blast fishing. Governments need to impose tighter rules on these industrials, such as tougher local building codes, and to put more effort into enforcing rules against overfishing.
Setting up marine protected areas could also help reefs. Locals who fear for their livelihoods could be given work as rangers with the job of looking after the reserves. Visitors to marine parks can be required to pay a special tax, like what has been done in the Caribbean.
Many reefs that have been damaged could benefit from restoration. Coral’s biodiversity offers hope, because the same coral will grow differently under different conditions. Corals of the western Pacific, for example, can withstand higher temperatures than the same species in the eastern Pacific, which proves a way forward to encourage corals to grow in new spots.

高三英语单项填空中等难度题查看答案及解析
There is a common belief among parents that schools are no longer interested in spelling. No school I have taught in has ever considered spelling unimportant as a basic skill. There are, however, quite different ideas about how to teach it, or how much priority (优先) it must be given over general language development and writing ability. The problem is how to encourage a child to express himself freely in writing without holding him back with spelling.
If spelling becomes the only point of his teacher's interest, clearly a bright child will be likely to "play safe". He will write only words within his spelling range. That's why teachers often encourage the early use of dictionaries and pay attention to content rather than technical ability.
I was once shocked to read on the bottom of a sensitive piece of writing about a personal experience: "This work is terrible! There are far too many spelling mistakes." It may have been a sharp criticism of the pupils' technical abilities in writing, but it was also a sad thing for the teacher who had omitted (略过)to read the composition, which contained some beautiful expressions of the child's deep feelings. The teacher was not wrong to draw attention to the mistakes, but if his priority had centered on the child's ideas, an expression of his disappointment with the presentation would have given the pupil more hope to seek improvement.
1.Teachers differ in their opinions about _______ .
A. the difficulties in teaching spelling
B. the necessity of teaching spelling
C. the importance of the basic writing skills
D. the role of spelling in general language development
2.The expression "play safe" probably means ______.
A. to write carefully
B. to avoid using words one is not sure of
C. to use dictionaries frequently
D. to do as teachers say
3.Teachers encourage the use of dictionaries so that______.
A. students will be able to express their ideas more freely.
B. teachers will have less trouble in correcting mistakes.
C. students will have more trust in writing.
D. students will learn to spell words correctly.
4.The main idea of the passage is _______.
A. the importance of developing writing skills
B. the importance of spelling
C. the correct way of marking composition
D. the relationship between spelling and the content of a composition

There is a popular belief among parents that schools are no longer interested in spelling. No school I have taught in has ever ignored spelling or considered it unimportant as a basic skill There are, however, vastly different ideas about how to teach it, or how much priority it must be given over in general language development and writing ability. The problem is, how to encourage a child to express himself freely and confidently in writing without holding him back with the complexities of spelling?
If spelling becomes the only focal point of his teacher's interest, clearly a bright child will be likely to "play safe". He will tend to write only words within his spelling range, choosing to avoid adventurous language. That's why teachers often encourage the early use of dictionaries and pay attention to content rather than technical ability.
