Дорогие, помогите ответить на вопросы по - английскому.

1 Frequent mention is made in this chapter of British individualism. How many examples of this can you find? Can you think of any others?

2 It has been said that the British are suspicious of things in public life which are logical or systematic. Can you find examples in this chapter which could be used to support this opinion?

3 Imagine this situation: you are at home, just about to have lunch, when there is a knock at the door. It is a British friend of yours, not a very close friend, but closer than a mere acquaintance. He or she has come to pay you an unexpected visit. You suggest that your friend comes in and stays for lunch. But your friend is embarrassed to find that he or she has called at

a mealtime and refuses the invitation. You want to persuade your friend to change his or her mind. Here are two possible ways of doing this: A Please stay. We don’t have much, I’m afraid, but we’d be honoured. Whatever we have is yours.

B It’s no trouble at all. There’s plenty of food. Don’t think twice about it. We’re used to people popping in.

Which of these two do you think would be a more successful way to persuade a British person? A or B? Why?

4 Which (if any) of the British characteristics described in this chapter would you regard as also characteristic of people in your country? To what extent?.
