Despite the bad reputation of sharks, they are crucial to the health of the marine ecosystem and can even help fight climate change.
In the shallows of Shark Bay, Western Australia, seagrass is food for the sea cows, which can weigh as much as 500 kg and eat roughly 40 kg of seagrass a day. Sea cows are a rich source of food for tiger sharks. By keeping the sea cow population in check, tiger sharks in Shark Bay help the seagrass thrive(茁壮成长).A booming seagrass meadow stores twice as much CO2 per square mile as forests typically do on land.
But tiger shark numbers are declining. Off Australia's northeast coast of Queensland, tiger sharks are estimated to have fallen by at least 71 percent, largely due to overfishing. A reduction in tiger sharks means more seagrass is eaten by herbivores(食草动物),which means less carbon stored in sea vegetation. This raised the question: What if sharks were absent from the Shark Bay—would the seagrass-dominated ecosystem survive?
To find out, researchers led by Rob Nowicki of Florida International University, spent time in Eastern Australia, where shark numbers were lower and sea cows ate seagrass largely undisturbed. "When unchecked, sea cows can rapidly destroy wide areas of seagrass," said Nowicki.
Those findings emphasised that tiger sharks were playing an important role in preventing the reduction of seagrass in Shark Bay. If shark populations continue to decline, the resilience of carbon-rich ocean ecosystems to extreme climate events like heatwaves will likely to be affected.
When it comes to boosting shark numbers, there has been a movement towards more sustainable fishing, but a large percentage of the industry have not changed their methods, which is a reason why the population of many marine top predators(捕食者)continues to decline.
Aside from supporting sustainable fishing, Nowicki said the only way to truly protect marine life is to reduce our global greenhouse gas emissions. "Ultimately, if we are going to protect our ecosystems in the centuries to come, we are going to need to solve climate change while undertaking species protection at the same time."

Archan Chan recalls her first experience working in a Chinese restaurant more than 14 years ago. Employed as an apprentice (学徒) chef, she was one of just two women in the kitchen —the other's only job was to beat eggs. "She was unbelievably fast at beating eggs. I guess for a woman to survive in a traditional Chinese kitchen back then, you had to be the best in something," she says.
Today, Chan leads the kitchen of Ho Lee Fook, one of Hong Kong's most popular restaurants. After spending more than a decade working in fine dining restaurants in Australia and Singapore, she is one of a few female chefs who have risen to the top of a high-end Chinese restaurant. That's an impressive achievement, given how unbelievably challenging it has been for women to show in high-end Chinese kitchens.
Female chefs have long been a minority in professional kitchens around the world. But the situation is even severer in Chinese kitchens. There's no denying the work is physically. demanding —an empty pot weighs about 2.2 kilograms. In the past, few chefs would risk employing a female trainer into that tough environment.
Given all of these barriers, not many women would even consider this male-dominated industry as an attractive career path. Thankfully, there are signs of a shift in mindset —the number of female Chinese head chefs has been rising in recent years.
"Even if it's 'a kitchen almost full of men, all everyone cares about is food - the cooking. They don't care if you're a male or female. Gender shouldn't matter," Chan says.
"Yes, there is a physical barrier-but I think the mental barrier may be more of a barrier to the increase of women in Chinese kitchens," Chan adds. "It isn't just about how much you want it but how much hard work you're willing to put into it. There are days when you feel like your arms are falling apart and you can't move them anymore, but the next day, you're stronger and may be able to work a heavier work."

C、Customers care about the gender of the chef. D、Women face both mental and physical barriers.(3)、Which of the following can best describe Archan Chan?A、Strong-willed. B、Open-minded. C、Cool-headed. D、Kind-hearted.(4)、What would be the best title for the text?A、Female chefs have risen to the top. B、Female chefs have long been a minority. C、Female chefs are proving doubters wrong.

The Book of Songs, also known as Shi Jing, is the oldest existing (collect) of Chinese poetry. Three years ago, when Chinese musician Fang Jinlong read Shi Jing, he was interested in the stories told through the poems. Because he couldn't (full) understand the ancient Chinese language (use) in the poems, he turned to experts whose elaboration further attracted him to explore the poems.
Then he decided to portray the poems with musical language by inviting composer Ma Jiuyue (create) an album. Titled Music andthe Book of Songs, the album was released on Jan 18, (feature) 10 original songs composed by Ma. They (perform) by Fang and won great popularity.
The 10 songs are based on 10 poems from Shi Jing, including Qiong Yao, which conveys gratitude to people who are eager to help others, Swallows, which (send) farewell messages to friends and Jia Yu, which portrays the scenes of a joyful banquet.
"Young people gave warm feedback about traditional Chinese music they had watched my performance. It inspired me to create more works for them, which helps popularize traditional Chinese music," says Fang.
"The 10 pieces sound (enjoy) and easy. For the listeners, it's a fresh way to comprehend poems from Shi Jing," says Ma. "We spent three years working on project. There are so many meanings in the poems and we want to display them as deep as possible with music," Ma says. "It's our mutual goal to have traditional Chinese music reach a wider audience."
