A team of scientists says that playing sounds underwater can get fish to return to areas with severely damaged coral reefs(珊瑚礁).In an experiment, they found fish returned after hearing recordings of the sounds like a healthy ocean reef. The research results were reported in Nature Communications.
The scientists placed underwater speakers in areas where coral had been dying in Australia’s northern Great Barrier Reef. They played the sounds over a period of about six weeks in 2017 and studied the results. The team reported that twice as many fish arrived in the areas where the sounds of healthy coral were played. The sounds also led to a 50 percent increase in the number of species present in the area, the researchers found. The researchers noted the importance of having many different kinds of fish return to the area. Different species of fish perform many activities that support the ocean environment and sea life.
Steve Simpson is a professor at the University of Exeter who helped lead the research. He explained, “Healthy coral reefs are remarkably noisy places. They contain the sounds of many kinds of shrimp, fish and other sea creatures. Young fish listen to these sounds when they are looking for a place to settle. Reefs become extremely quiet when they suffer destruction that is usually related to human-caused pollution. Coral damage can drive shrimp and fish away. But the experiment suggested that the use of underwater loudspeakers was an effective way to get young fish to come back.”
Mark Meekan is a fish biologist. He said that the return of the fish is the first step towards seeing major improvements in reef health. “Recovery is underpinned (巩固) by fish that clean the reef and create space for corals to regrow,” he said. University of Bristol professor, Andy Radford, said the underwater sounds are a promising way to fight coral reef damage at the local community level. But he noted that other threats need to be reduced as well. These include climate change, pollution and over fishing.

The second little pig was unlucky. He built his house from sticks. It was blown away by a wolf. His brother, by contrast, built a strong house from bricks to prevent the wolf’s attack. However, in the real world it would help reduce pollution and slow global warming if more builders copied the wood-loving second pig.
Governments in the rich world are now trying to promote greener behavior by forcing developers to build new projects to “zero carbon” standards. These standards are less green than they seem. Wind turbines (涡轮) and solar panels on top of buildings look good but are much less productive than wind and solar farms. And the standards only count the emissions from running a building, not those given out when it was made. Those are thought to account for between 30% and 60% of the total over a structure’s lifetime.
Buildings can become greener. They can be made of more recycled wood and parts of them can be prefabricated in off-site factories, greatly reducing truck journeys. But no other building material has environmental certificates as exciting and overlooked as wood. The energy required to produce a wooden beam is one-sixth of that required for a steel one of comparable strength. When a mature tree is cut down, a new one can be planted to replace it, capturing more carbon. After buildings are pulled down, old wooden beams and boards are easy to recycle into new structures. Wood is also a good insulator (隔热材料). A softwood window frame provides nearly 400 times as much insulation as a plain steel and over a thousand times as much as an aluminium (铝) frame.
Carpenters’ efforts alone will not bring the environmental cost of the world’s buildings into line. But using wood can do much more than what is appreciated. Thus, the second little pig was not wrong, just before his time.

After having her second child in 2012, Victoria was jobless and lost her clear direction. She found herself suffering depression. “My sister, Karen, suggested I try selling something to do with weddings on eBay,” she said, “when the children were asleep, I learned to design invitations on my laptop. Because I already had a laptop and a printer, the only startup costs were buying some cards and envelopes.”
Victoria listed what she made for sale on eBay, but weeks and months passed and she hardly had any sales. Concerned, Karen suggested she should change the designs but Victoria firmly believed that her design was good.
But in January 2013, everything changed dramatically. “I remember getting out of the bath one night and I’d made nearly ￡200 in orders in the time it had taken to have a bath. Now the demand was so huge that I had to buy a bulk-load of cards and envelopes and purchase another printer. I started to work at 7 pm each night and worked into the early hours.” Victoria believes that her affordable wedding invitations are the key.
Having something else to focus on, the fog of depression soon lifted. By the end of January she had made an impressive ￡8,000 in just one month. The business now turns over an incredible ￡80,000 a year, half of which is profit. She continued: “The money has allowed us to upgrade to a three-bedroom house and we have had some great family holidays.” In October, Victoria was one of eleven eBay sellers recognized at the eBay for Business Awards.
“I want to show to other women with little or no experience that even if you’re struggling as I did, you can be a mother and a businesswoman and do both successfully,” smiles Victoria. “I’m a one-woman band but it’s more than enough for me!”
1.What made the most contribution to Victoria’s success?
A.The advice from her sister.
B.The design of the invitations.

A.￡200. B.￡8,000.
C.￡40,000. D.￡80,000.
3.What personality does Victoria probably have?
A.Cautious. B.Sensitive.
C.Easygoing. D.Determined.

I was so sorry to know you’re having so a bad time at the moment. The truth is everyone will have a bad time when things seem to being wrong. The important thing is to learn to control your temper.
First, you are supposing to talk to someone you trust about how you feel. This is a good way on which you can let your anger out without hurting others or themselves. Second, playing team games with your friends as physical exercise is an effective way to get the rid of anger. And third, remain optimistically about your future. A positive attitude towards life can be of great help with your spirit.
