《Unit 15 We’re trying to save the manatees!-Manatee of theMonth》文章素材Flicker checks out a researcher doing manateephoto identification work. (Photo courtesy of FWCC)When you first see Flicker, you can't help but notice the many small propeller scars that run across her back. When she was identified in 1983 near Ft. Myers, Florida, a Florida Fish and Wildlife Conservation Commission (FWCC) researcher commented that h er scars looked like flickering flame s. That's how she got her name.Flicker has had more than one run-in with a boat. Her tail is missing a few chunks from contact with a propeller, and she's also had her share of entanglement woes (more on that later). But that hasn't stopped her from racking up manatee miles on her frequent trips around Tampa Bay.In the winter, Flicker hangs out at Tampa Electric Company's (TECO) power p lant in Apollo Beach, Florida. Manatees can't tol erate water temperatures below 21° C (70° F), and they gather near natural springs or warmw ater outflow of power plants when the weather turnscolder. Besides visiting the TECO plant, Flicker alsomakes trips across the bay to the Florida Progress plant in Bartow. After all, she doesn't want to play favorites!Her distinctive scars resemble "flickering flames" and earned Flicker her nameA few years ago, Flicker literally got caught up in some trouble that turned into a real adventure for her and her rescuers. One day, residents of Coffeepot Bayou in Tampa Bay reported a manatee with a crab trap line and a bouy wrapped around her tail. It was Flicker. But the extra additions didn't slow her down. She towed the line and bouy almost 10 nautical miles across the bay! Then she turned north to the Alafia River where she picked up more line and another bouy.And then she got caught in two mooring lines attached to a houseboat.By the time the FWCC rescue staff had arrived, Flicker -- who is a big manatee -- had stripped off one of the bouys and almost swamped a law enforcement boat. It took three attempts by the rescue staff (along with a couple of cleats and several planks from the houseboat) before she was free.Both Flicker and her rescuers escaped with no injuries. And she's still continuing to trek across Tampa Bay. In fact, last winter, she was a bay-wide traveler, visiting TECO, the Florida Progress' power plant, and Culbreath Key (across the bay from Florida Progress) all in one year. The winte r fluctuated between cold and warmweather, and Flicker may have decided to hightail it to Bartow when things warmed up a bit. The warm water disperses faster there on the unp rotected flats, but lush seagrass beds can be found, so there are always good eats!We're happy to report that last spring Flicker was spotted with six other adults in the Culbreath Isles area -- in an area newly protected by boat speed zones for manatees.Flicker keeps on truckin' across Tampa Bay.

and reviewed some grammar． Now who can make sentences using the grammar we reviewed yesterday．S1 : I’m answering a question．S2 : My mother goes shopping every week．S3 : She used to live in the countryside, but now she lives in the city．S4 : He was made to do so．S5 : She has learned a lot of new words．T: Very good．Step Ⅱ3aThis activity provides reading practice u-sing the target language． Show the key vocabulary words on the screen by a projector．Read the words and ask students to re-peat again and again until they can pronounce the words fluently and accurately． Go through the instructions with the whole class．Invite a student to read the letter to the class． Correct any pronunciation errors to make sure the student is providing a good model for the rest of the class．Get students to read the letter on their own again and underline the reasons why the writer is opposed to zoos．Check the answers with the class．AnswersZoos are terrible places for animals to live．The animals are kept in tiny cages and can hardly move at all．And they are only given food once a day．Notes1． tiny—very small2． Culture note: Many Westerners are extremely concerned about animal welfare and often support organization to protect them． Such protection includes the ethical treatment of farm animals and animals in zoos． Some people feel that we should not eat any food made from animals or wear any animal products, including leather shoes．Step Ⅲ 3bThis activity provides reading and writing practice using the target language．go through the instructions with the class．Invite a student to read the letter to the class． Correct any pronunciation errors to make sure the student is providing a good model for the rest of the class．Ask students to read the letter again． Then finish the work on their own or in pairs． When they work, walk around the classroom, checking the progress of the pairs and offering help as needed．Check the answers． Answers will vary but a good letter will take the points from the letter opposite to their point of view and argue with them．A sample answerDear Editor,After reading the two letters, I realize that I must say something about animals and zoos． I don’t agree with Disgusted． In fact, many animals only eat once a day or once every few days, so feeding them just once a day is not a problem at all． I think zoos are very important to animals． They can stop many endangered animals from being killed or hunted． They can provide man with places for research work． Also we can visit the animals in the zoos to learn some knowledge to protect the animals better．Sincerely,×××Write the letter on the blackboard as an example．Notes1． living—active: lively2． care for—look after; provide food, money, shelter, etc．3． urge—request earnestly; try to persuade; strongly recommendStep Ⅳ Part 4This activity provides oral practice using the target language．Go through the instructions with the class． There will be two different teams． One team will talk about why zoos are good places for animals and the other team will say why zoos are bad paces for animals．Look at the list of expressions． Invite a student to read the list aloud to the class． Then get some students to use each expression in a complete sentence．S1 : I think that elephants shouldn’t be kept in zoos．S2 : I believe that animals in zoos live longer than animals in the jungle．Put students in two teams． Let each team work together as they write down some statements showing their viewpoint, using the expressions in the box．Look at the sample language in the box． Invite a pair of students to read it to the class．S A : I think that animals should not live in zoos．S B: I disagree with you． I feel that zoos provide clean and safe places for endangered animals to live．Ask the two teams to debate in class．First, call on one team to give a statement． Then ask the other team to give a statement that is related to the first statement． Help the teams make several different statements about a single point before going on to another point．For example:Team 1: I think that zoos are not suitable for animals to live in．Team 2: Why do you think so?Team 1: Because animals there are only given food once a day． They’re hungry．Team 2: I disagree with you． I believe that many animals only eat once a day or once every few days． So, there is no need to worry about that．Step Ⅴ SummaryIn this class, we’ve learned some key vocabulary words such as against, be suitable for, tiny cages, care for, urge． We’ve also done a lot of reading, writing andspeaking practice using the target language．Step Ⅵ Homework1． Finish off the exercises on pages 61～62 of the workbook．2． Write the letter to the editor．Step Ⅶ Blackboard DesignUnit 15 We’re trying to save the

the instructions aloud to the class．Then ask, What’s the meaning of the phrase save the planet．（It means to keep planet Earth clean and not polluted．）Look at the five suggestions for ways to save the planet． Invite a student to read each one aloud to the class． Make sure students understand the meaning of each suggestion．stop riding in cars．recycle books and paper．turn off the lights when you leave a room．turn off the shower while you are washing your hair．don’t use paper towels or napkins．Get students to write a number 1 in front of the easiest thing to do, a number 2 in front of the second easiest thing to do, and so forth． Check the answers． Students will probably have different answers． Let one of the students to say why he or she thinks a certain thing is easy to do and another thing is difficult to do． For example: I think it is easy to turn off the lights when you leave room． Because everyone can do it without any effort． It is difficult to stop riding in cars． Many people go to work or go to school by car, because it is far away from their homes． Otherwise they will be late．Notes1． stop doing—discontinue doing2． recycle—treat so that further use is possibleStep Ⅲ 1bThis activity provides guided oral practice using the target language． Read the instructions to the class． You will compare the answers you wrote for Activity la．Look at the example

Topic ReadingPandas’ problem憨态可掬的熊猫是中国的国宝。
可它的食物——竹子正在一天天减少。
我们该怎么做呢？Suppose every person on Earth ate only one kind of food. And maybe that food couldn’t be found in one year. If that happened, man would soon die. Luckily, man doesn’t have to face that problem. But another animal may. It is the panda, one of the world’s most-loved animals.Dr Thomas Soderstrom, a scientist, has found for the first time that the (1) bamboo that pandas only eat is dying. As a result, many pand as are also dying of hunger. Scientists estimate (估计) that so far more than 140 pandas have died. This number may be almost one quarter of the world’s panda population. Between 400 and 1,000 pandas are thought to live in the mountains.Pandas were more common in many parts of Asia in the past. But now they are only in small parts of China. Can the (2) wild panda be kept?Scientists want to find out more about the animal’s food. They want to see whether pandas are able to change their food. Chinese scientists are trying to (3) raise more pandas in zoos. The firs t baby panda was born in the Beijing Zoo in the autumn of 1978.【Enrich your collection】die v. 死亡其现在分词形式是dying ，也作形容词(临死的；快要灭绝的)；过去式、过去分词是 died；death 是名词，意为“死亡”；dead 是形容词，意为“已死的”。

When they work, the rest of students also guess what animals they are talking about.Step Ⅱ2aThis activity provides guided listening practice using the target language.Look at the picture. Ask, What can you see in the picture? (A manatee is in the water.)Go through the instructions with the class. You will hear two people talking about manatees. Listen and draw a line between each word and its definition.Read the sample answer. Then say, The word endangered means there aren't very many of this animal left in the world. The manatee is endangered because there aren't very many of these animals.Play the recording for students the first time. This time students only listen to the recording carefully. Play the recording a second time. This time students draw lines between each word and its definition.Check the answers with the class.Answers1．b 2．d 3．a 4．cTapescriptBoy: Can you tell us about the manatees, please?Man: Sure. We're trying to save them.Boy: Why? Are they endangered?Man: Yes. There used to be a lot of manatees, but now there aren't very many of them.Boy: Do you know how many there are?Man: At this point, there are only about 2 500 in the U. S.
