(二)阅读下面材料，根据要求回答问题。 “Someone once asked me, ‘What's the tool you would want to give any student？’ And I said, ‘A mask and snorkel (潜水通气管) set，’” the ocean biologist Thys says in a video.And Thys explains, “About seventy－one percent of the Earth is the ocean.It's worth a view.” Thys has devoted her career to seeing the ocean, and to helping others watch the great diversity of the underwater world.A big part of what motivates her work is the chance to let people develop a sense of respect for the grandness of the ocean, and to get people to participate in efforts to protect endangered ocean ecosystems. Since studying ocean biology, Thys has focused her research on how sea animals live.One animal she particularly studies is the ocean sunfish.“It's so different from any other fish，” says Thys.“It looks like a mistake.Where does the tail go？” Thys adds.“The sunfish provides an entry point to understanding more about the behavior of creatures in the ocean, and about how environmental changes impact underwater ecosystems.” Thys's work also takes her above ground, where she's looking at ways to create new connections between human populations and natural environments to help address social and environmental challenges.For instance, she's working on nature's effects on mental well－being. Thys's passion for her work is evident in every lecture, video, and public appearance she makes.Using the media, Thys encourages people to learn about the ocean and love it.Due to many ocean research projects and activities from the media, Thys is up to her neck in work every day.She could hardly spare plenty of time for a good rest.Thys's devotion to her work as an ocean scientist and ecological warrior is infectious.She's a role model and an inspiring guide to ocean life. Questions： 1．Why would Thys like to send students a mask and snorkel set? To encourage them to explore the ocean. 2．What greatly motivates Thys's work according to paragraph 2? The chance to let people respect and protect the ocean. 3．What does Thys think of the ocean sunfish? It is unique and has great scientific value. 4．What's your attitude towards Thys and her work? She's a respectable scientist and her work is not only meaningful but also can make a big difference to the Earth. 学科网（北京）股份有限公司 $
