In 2014，Xu Yitang，a Beijing native who had been studying Peking Opera since childhood，went with friends for a birthday celebration to Beijing Zoo.Little did he know that a chance encounter at the aquarium there would excite a lifelong passion.As Xu Yitang stared at corals bathed in tank’s light，a sense of wonder crowded into his mind.Lost in the beauty and mystery of the creatures，he spent the entire afternoon in front of it.After that，he began to frequent the local market to learn about coral farming from merchants who sell ornamental plants，fish and corals.He also searched for information on relevant forums online.Before long，he had set up a small fish tank at home and started cultivating a coral.

Nowadays，Xu Yitang，who has moved to the tropical island of South China’s Hainan Province，works for a Sanya-based tropical biological laboratory belonging to the Chinese Academy of Sciences.Each day，he spends several hours diving deep under the waves to observe and document the growth and development of the creatures that captured his heart all those years ago.Nicknamed “coral man”，he is actively engaged on such social media platforms as SinaWeibo，where he regularly shares visually beautiful photos and entertaining videos of corals.He aims to encourage individuals to take action in protecting coral reefs and the oceans as a whole from the destructive impact of climate change and human activities.

In the laboratory，he would film educational videos to raise awareness and knowledge about corals，so that people can learn how to protect them effectively.

Ⅳ.七选五(共5题；每小题2.5分，共12.5分)

Food is part of who we are.We all need it，survive because of it and derive happiness from it.So if food matters so much，why do we let so much of it go rotten in our fridges，or get thrown out in our stores? Sadly，we love food，but we don’t take care of it.1 Here are ways to help us love our food better and grow respect for the world behind what we eat.

• Reduce your food waste.

Buy only the food you need，store food wisely，donate excess and turn leftover food into the next day’s meals.When we waste food，all the resources used for growing，processing，transporting and marketing that food are wasted too.2

• Support your local food producers.

Chefs get awards，stars and recognition for their creations.But what about our farmers? 3 Shop at your local markets and get to know your farmers.Giving them your business is giving them your recognition and respect.

• Adopt a healthier，more sustainable diet.

4We get energy and maintain health from good food.We normally don’t care the power that food and nutrition have over our bodies.Too much of it，or too much of only one kind of it，can lead to obesity，deficiencies or diet-related diseases.

•5

By treating each meal with pride，we respect the farmers who produced it，and the resources that went into it.Respect can be passed on.Talk to the people around and to the next generation about making informed，healthy and sustainable food choices.

Respecting food means appreciating the back-story of food.When we know the full picture，it is easier to see what our food really stands for and how precious it really is.

A．Have a conversation.

B．Learn where food comes from.

C．Our bodies consume calories and nutrients.

D．For many people on the planet，food is giving.

E．Food is so much more than what is on our plates.

F．One third of all food produced globally is lost or wasted.

G．Without them，we wouldn’t have the fresh food we need on a daily basis.
