[00:52.92]Hey,Ginny.
[00:53.95]What's that big,furry animal in the pond?
[00:56.82]It's a polar bear,Victor.
[00:58.48]They're kind of aggressive.Are they?
[01:00.90]Looks like they really love water,
[01:02.61]Uh-huh.And what do you call those big,
[01:05.69]gray things in the water?
[01:07.03]They're called manatees.What?
[01:09.59]Manatees.They're very gentle and very shy.
[01:13.10]Oh.And how about the yellow
[01:15.21]and black spotted animals in that cage?
[01:17.98]They're cheetahs⁵.
[01:19.41]The cheetah⁴ is the fastest animal on earth.
[01:23.71]1c GROUPWORK
[01:27.52]Think of an animal that is the same as you
[01:30.25]in some ways.
[01:32.47]Write a statement about you and the animal.

[01:39.96]of the animal.
[01:41.94]Your classmates guess what kind of animal
[01:44.82]you are like.
[01:46.78]I am like this animal because I am strong and
[01:50.27]intelligent.
[01:51.71]I like water,and I like to eat vegetables.
[01:55.81]You're like an elephant.
[01:57.74]No.You're like a manatee¹.
[02:01.02]Yes!
[02:03.34]2a Listen and match the words with definitions.
[02:09.93]Can you tell us about the manatees,please?
[02:12.64]Sure.We're trying to save them.
[02:15.29]Why?Are they endangered?
[02:17.28]Yes.There used to be a lot of manatees,
[02:20.32]but now there aren't very many of them.

[02:38.97]Their favorite habitat is the water under the
[02:41.50]trees in mangrove⁶ swamps⁷.
[02:43.28]And why are they endangered?

[02:47.97]Also,there sometimes isn't enough food
[02:50.30]for all of them.
[02:52.15]As you can see,they're large.
[02:54.51]The average manatee is about ten feet long
[02:57.61]and weighs about 1,000 pounds.
[03:00.23]They need about 100 pounds of aquatic⁸ feed a day
[03:04.22]Aquatic feed?

[05:22.64]3a Read the letter to the editor and underline
[05:27.00]the reasons why the writer is against the zoos
[05:31.73]Dear Editor,
[05:34.10]I am writing to say that I am against building
[05:37.18]a new zoo in our town.
[05:39.57]Zoos are terrible places for animals to live.
[05:44.09]I've visited a lot of zoos in my life,
[05:46.67]and I have never seen one I liked or one
[05:49.36]that was suitable for animals to live in .
[05:52.89]Just last week,I visited a zoo and couldn't
[05:56.77]believe what I saw.
[05:59.07]The animals are kept in tiny cages
[06:01.82]and can hardly move at all.
[06:04.93]And they are only given food once a day.
[06:08.23]Is this a good way for animals to live?
[06:11.43]I don't think so.
[06:13.45]Sincerely,      Disgusted
[06:17.90]3b Now read this letter to the editor.
[06:22.46]Do you agree with "Disgusted"or "Animal Friend"?
[06:27.04]Write a letter to the editor
[06:28.78]and give your opinion.
[06:32.09]Dear Editor,
[06:34.08]I visited our zoo yesterday and I was very
[06:37.34]surprised to find hardly anyone there.
[06:40.70]Zoos are very important places.
[06:43.78]They are like living textbooks for young people.
[06:47.46]They provide homes for many endangered animals
[06:50.39]and help to educate the public about
[06:52.18]caring for them.
[06:54.16]If we don't support our zoos,
[06:55.97]they won't have enough money to take care of
[06:58.24]so many fine animals.
[07:00.60]I urge all of your readers to visit our
[07:02.90]wonderful zoo soon.
[07:04.84]Sincerely       Animal Friend
[07:08.34]4 DEBATE
[07:11.39]Make two debate teams.
[07:14.50]Team A,you think zoos are not good for animals.
[07:19.66]Team B,you disagree.
[07:22.75]Take turns giving your opinions.
[07:25.65]Use the expressions below.
[07:28.53]Useful expressions
[07:31.02]I think that...
