7、we took pictures of their fins.()Finally,we contacted other whale research groups around the world to share the information with them.(1)First,we followed a group of whales with the boat.()Later,we created a database of their fins and locations.67342853Listen to the conversation again and answer the
8、 questions.1.How many species of whales are there?2.What is the criterion to divide the main types of whales?3.What do whales use sounds for?4.Why do the campers take pictures of the whales fins?5.Why do they contact other research groups?Over 80.The criterion is whether they have teeth or not.They
9、use sounds to communicate and hunt.This can help them to tell the whales apart.They want to share information with them.4Some of the students could not make it to thecamp.Imagine you were there.Tell your partnerabout what happened,using the expressions inthe box below.Your partner can also ask quest

15、o?What other sea animals would you like to see?What would you like to know about these sea animals?Where are they?At Sea World in Queenland,AustraliaAt the Houston Aquarium in the United StatesIn the Galapagos Islands,EcuadorTalk with your partner and make a plan for a trip to see the animals.Your p

17、ition of saving sharks.Then we can go to see the seahorses whose number declined greatly for the past decade.However,most people do not know much about seahorses at all.I think we need to raise awareness about seahorses and marine conservation in China.The last spot will be The Chinese Pavilion,which displays the aquatic organisms and bio-system in the Yangtze River and some national endangered rare aquatic creatures,like Chinese alligator and Chinese Sturgeon.
