Сообщение темы урока, мотивация учащихся Эвристическое введение темы Do you know this gentleman? Right, this is Sherlock Holmes, a perfect gentleman, a brilliant erudite and an ideal interlocutor. What’s he famous for? (He is famous for deductive methods of reasoning). He is the acknowledged master of observation, analysis and imagination. Would you like to adopt his deductive approach? Then you must meet our special guests. 2
Обзор пройденного материала по теме “Модальные глаголы” Фронтальная работа с классом в режиме “объяснение-вопрос-ответ” Our first honoured guest is the modal verb must.

When do we use the modal must? (when it is necessary to do something or when we think something is probably true because nothing else seems possible).

Today we’ll concentrate on the second meaning of must. We’ll use it to say that something is highly probable based on the information or evidence we have.

3
  We use the modal must when we are 90% sure that something is true. 4
If A is bigger than B and B is bigger than C, it follows that A must be bigger than C. 5-7
Let’s apply deductive reasoning to make a guess. Look at the best pupil in his class. Do you think he studies hard?

(He must study very hard).

8-9
Can we say that he is a clever boy? (He must be clever). 10
This restaurant is always full of people. Do you think it’s good? (It must be good). 11-12
There is a long queue at the cinema. What is the film like? (The film must be interesting). 13-14
Обзор пройденного материала по теме “Система инфинитивов английского языка”   What types of infinitives do we know?

Which infinitive do we use to describe regular habitual action or situation? (Simple infinitive)

15
Which infinitive is used to describe an action in progress? (Progressive)

Can you hear anything? What does it sound like? (It must be raining).

Which infinitive is used for an action that has already been completed? (Perfect Infinitive) 19
Suppose you come into your room and see a coffee stain on the table. Do you have any idea what happened? (Someone must have spilt coffee). 20-21
There was a long queue at the cinema yesterday. What do you think the film was like? (The film must have been interesting).  

22-23

And what is the opposite of the modal must in deductive reasoning? (the modal can’t)

We use can’t when we are sure that something is impossible. We don’t use mustn’t in such situations.

24-25
Look at this boy. He always gets bad marks. Does he study hard? (He can’t study hard). 26-27
He got a bad mark yesterday. Do you think he studied hard yesterday? (He can’t have studied hard yesterday). 28-29
Воспроизведение изученного и его применение в стандартных условиях. Рассказ об исторических событиях с последующим выполнением грамматического упражнения с элементами дедуктивного анализа Let’s listen to a short mini story. It happened a long time ago. As you know, in the 17 century England the official religion of the country was Protestantism. The life of Catholics was miserable. In 1605 a group of Roman Catholics rented the cellar under the Houses of Parliament. Later they involved Guy Fawkes into their plot. On the 4th of November Guy Fawkes was found in the cellar next to 36 barrels of gunpowder. The King’s men arrested and executed him.

Use your brainpower to guess what really happened. Insert must or can’t.

30-34
Roman Catholics can’t have been glad with the politics of the Protestant parliament.

The conspirators must have tried to get rid of the Protestant parliament.

Guy Fawkes must have shared the conspirators’ ideas.

Guy Fawkes must have tried to blow up the parliament.

Guy Fawkes can’t have been the leader of the plot.

35-39
Расширение сведений по теме “Модальные глаголы” Фронтальная работа с классом в режиме “объяснение-вопрос-ответ” What modal do we use when we are less sure of something? (Might or could)

We use might/could when we think that something is less probable.

For example, Kate is not at school today. What are the possible reasons? (She might be ill).

Neither was she at school yesterday. (She might have been ill).

This restaurant is always empty. Give any possible reason for that. (It might be expensive).

Задание на дом, подведение итогов урока.   Write down your ideas about the criminal’s interests and hobbies. Where can the criminal have recently been? Can you guess at the criminal’s age and sex? You will need the modals must, can’t, might. Don’t forget the three basic principles which made Sherlock Holmes so efficient: observation, analysis and imagination. Use all of them and create your own version of what happened at the art gallery last week.
