Editorial notes

  • Exercise 11, Question 6: shall expresses an order in the textbook’s traditional modal usage.
  • Exercise 12, Question 4: might is suggested for reported possibility, though the original sentence does not provide enough context to establish the intended modal conclusively.
  • Exercise 14, Question 7: can is the likely intended choice, but the more natural written form is “cannot.”
  • Exercise 15, Question 10: “I must do or die” is retained as printed; its intended meaning is compulsion or determination.
  • Exercise 16, Question 8: The printed cue says “necessity,” but need not expresses absence of necessity. The answer follows the likely intended construction of the sentence rather than the cue.
