“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
 
2.What greatly motivates Thys's work according to paragraph 2
 
 
3.What does Thys think of the ocean sunfish
 
4.What's your attitude towards Thys and her work

主题活动 海洋的故事
阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
A long time ago, humans did not walk on land, but would rather swim.There was a boy who enjoyed it the most, and his name was Kristaps, who had short brown hair, which felt as soft as a teddy (泰迪) bear's fur.He lived in the part of the sea where many fish came out every day.Kristaps was always jealous, and he would always want everything his friends had and also when someone got an accomplishment he would get mad, as mad as a bull spotting the color red.Kristaps and his best friend Joel always went into the heart of the sea, but they never went too close, because if they disturbed the god of the sea Poseidon, he would hurt them.Joel was Kristaps's truthful friend.Joel always congratulated Kristaps on his accomplishments.He was a modest man.He and Kristaps would love to hunt for fish every day.One dark Thursday, Kristaps and Joel went out to hunt for food.After about an hour of searching, Kristaps and Joel were about to give up.
“Let's go home.It seems like all the fish stayed at home on this dark day,” suggested Joel.
“No, I can feel the fish.They always come outside to play,” responded Kristaps.
Joel was about to leave for home but then at the last moment, all the fish from the sea came out all at once.What they didn't know was that Poseidon had come out with the fish that day.Joel went to grab some fish.Poseidon noticed that and he went after Joel.Poseidon hated seeing humans grab his fish.It was like seeing a family member get killed.
“I dare that boy to kill my fish, and if he does, he will be given a punishment and so will his friend,” said Poseidon angrily.
“Joel, watch out!” shouted Kristaps as Poseidon grabbed Joel from the bottom.
“I will return your dear friend if you can get me all the gold in the sea,” said Poseidon angrily.

(Text 1)
M:I'm on the beach to talk to Mel Flynn, an Australian teenager who spends most of her free time underwater.Hello, Mel.
W:Hi.
M:How did you become interested in diving
W:I grew up near the beach, and I liked watching little fish.My parents say they knew I'd work with fish when I got older.They're both biologists, but more interested in land animals.When I was old enough, I asked if I could go diving so that I could take a closer look at all the amazing things living underwater.
M:When did you start to dive
W:I learned to swim when I was three.But I had to wait to seven years to dive.But even then we couldn't go deeper than twelve meters.
(Text 2)
M:I just looked through that article about plastic pollution online.It's shocking to see the extent of damage we're doing to our oceans.There are also pictures of the polluted ocean.The floating plastic takes away from the beauty of the oceans.Besides, I've heard that plastic can disrupt the normal operations of ships at sea.
W:With 300 million tons of plastic produced yearly, most of them end up in the oceans, endangering marine life and eventually our own health through seafood.
M:It's alarming! The problem seems so vast.
W:Small steps make a big difference.Reducing personal plastic consumption is a start.Consider carrying reusable bags and recycling whenever possible.
M:True.I've even added a metal straw to my backpack essentials.
W:Brilliant! Also, there are beach cleanup events every month.Participating in them also helps.
M:I'd love to join the next one.Let's make a commitment: Give up store bought bottled water and bring our own bottles instead every day.
W:Deal! Together, we can inspire others and create a ripple effect.

Taking a Bus vacation Holiday
My family and I went to Honolulu, Hawaii during summer vacation.Honolulu is on a small island in the North Pacific Ocean.
We took a special kind of tour bus called the “trolley” to different tourist spots.It has a one ticket system where you can get off at any stop, look around, and then get on the incoming trolley to the next stop.
We went to the duty free shops, China Town, and a large shopping center.There were many things on the route, like famous name brand shops, restaurants, and convenience stores.
We met people from many places around the world, such as Beijing, Shanghai, Seoul, Osaka, and Tokyo.It was a very nice stay there in Honolulu.
Looking and Speaking
1.The topic of the pictures above is about “some famous navigators in history”.
2.Christopher Columbus, an Italian explorer and navigator, one of the main figures in the era of great navigation, is the pioneer of great geographical discovery.
Zheng He's voyages to the western seas were an unprecedented feat in the world's maritime history at the beginning of the 15th century, playing a positive role in the economic and cultural exchanges between China and foreign countries.Zheng He himself showed his diplomatic skills, military strategies and spiritual qualities in this historical event, and won the respect and commemoration of the world.
The shipping route opened by Vasco promoted the development of commercial relations between Europe and Asia, and indirectly created favorable conditions for European powers to colonize Asian countries.
Bartolomeu Dias became the first European mariner to round the southern tip of Africa, opening the way for a sea route from Europe to Asia, and increasing trade with India and other Asian powers. It also prompted Christopher Columbus to seek a new royal patron for a mission to establish his own sea route to the Far East.
Reading
1.To encourage them to explore the ocean.
2.The chance to let people respect and protect the ocean.
3.It is unique and has great scientific value.
4.She's a respectable scientist and her work is quite meaningful which can make a big difference to the Earth.

参考范文:
Kristaps went to the darkest part of the sea where most of the gold was at.He thought that they hadn't discovered the gold that existed here for many years.Kristaps was worried and he felt as if it were the last day on earth.But he knew that if he wanted to save his dear friend, he must become brave.Even if he lost everything, he should do all he could.Suddenly a plan occurred to him.He decided to try and fool Poseidon.
At last, Kristaps found the gold, but he wanted to keep it for himself.So Kristaps quickly grabbed gold paper and rubbed it into the ball like real gold to take it to Poseidon to save his friend.“Hopefully I can fool Poseidon for Joel,” thought Kristaps.However, the gold in Poseidon's hand accidentally cut Poseidon.As a result, Poseidon shouted at him angrily.Because of Kristaps and Joel, now humans have to live on land and cannot survive in the sea forever.
