17. Laura said that when she_________ to school, she saw an accident.
A. was walking B. has walked C. had been walking D. has been walking
A or C.
A and C both tell us she walked to school in the past. A implies she is no longer walking to school, while C implies she no longer walks to school (A is a past event, C is a habitual event).
B and D are wrong because "has walked "and "saw" don't match.
41. John asked me _______ in English.
A. what does this word mean B. what that word means
C. what did this word mean D. what that word meant
Which one is correct in each question and why?
B or D
B for the current meaning and D for the meaning in the past.
A and C only work if you are quoting what John asked, but there are no speech marks.
