Teacher: There is a nice saying on the blackboard today. Will you read and translate?

Pupil: We do not own the Earth we have borrowed it from the future generation.

Teacher: What does it mean? (На доске написаны опорные словосочетания: "take care of …", "think only about today", "keep … for your children").

Teacher: Will you tell us about the animals who are in danger today?

Сильные учащиеся готовили сообщения и вопросы для группы. Темы сообщений: "The Blue Whale", "Monk Seal", "Leopards", "Passenger pigeon". На одном уроке нет возможности выслушать всех, поэтому остальные темы прозвучали на последующих занятиях.

Teacher: What can you do to solve the problem? Make sentences using modal verbs.

5. Role-play.

Teacher: Are you a vegetarian, Alex? It is good or bad to be a vegetarian? Are you for or against? Let's have a role-play. I'll give you cards that divide you into two teams: "for" and "against". Let's listen to your discussion: "To be or not to be a veggie". Don't forget to use the phrases of spoken etiquette.

Учитель раздаёт карточки.

P.1: It's stupid to say everybody must be a vegetarian. In some places, it's very difficult to get enough to eat. People have to eat what they can get.

P.2: I don't really care if I eat meat or not, but my parents say I must. Maybe when I'm older.

P.3: The thought of eating a dead animal actually makes me sick.

P.4: Vegetarianism is silly. You can't live forever on cucumbers and apples, can you?

P.5: I'll never become a vegetarian. I love fast food so I eat lots of hot dogs and hamburgers.

P.6: Animals don't wish to be killed and would like to enjoy life to the full, just as any human would. Killing animals is a crime.

P.7: You never see a tiger or a lion feeling sorry for its victim, do you?

P.8: Why is killing an animal different from killing a human?

P.9: I don't think it's necessary to kill to eat. It's cruel to let animals suffer so much.

P.10: If you went to the slaughterhouse to see how animals are killed, you wouldn't eat meat.

Учитель направляет ход дискуссии. Учащиеся должны, выслушав мнение, согласиться или возразить, используя речевые клише: "I think you're mistaken", "I fully agree with you" и т.д.

Teacher: Have you ever thought of your future? Do you think the people of tomorrow will be happier that we are?

Звучит отрывок из песни Джона Леннона "Imagine".

Teacher: I shall read you a sentence. If it is optimistic raise your red card, if it is pessimistic - a blue one (перед уроком учащиеся получили карточки двух цветов).

1. In future people will live longer, many diseases will disappear.

2. People will cut down all the forests.

3. There will be no fish in the rivers.

4. We shall be able to control the weather.

5. We shall not be able to breathe without a gas mask on.

6. We shall exhaust all the resources.

7. There won't be any conflicts between people.

8. We shall find new sources of energy.

6. Заключительная часть урока. Подведение итогов.

Teacher: What can you do to keep the Earth clean and healthy? You should be a friend to her. Will you read a poem "Hug the Earth"?

Walking along feeling free,
Feeling the earth here with me,
And I love her, she loves me,
I hug the Earth, the Earth hugs me.
She's our friend,
We'd like to be together forever.
The earth is a garden,
It's a beautiful place
For all living creatures,
For all the human race.
Helping Mother Earth,
We can peacefully roam,
We all deserve a place,
We can call our home.
