Mr Sherlock Holmes (0 – sit) __was sitting__ one morning at the breakfast table in his room in Baker Street. His friend Dr Watson (1 – stand) near the window examining a walking stick which a visitor (2 – leave) the day before. “To Dr Mortimer, from his friend,” (3 – write) upon it.
Sherlock Holmes suddenly (4 – turn) to Watson , “The owner of the stick (5 – have) a dog which (6 – be) larger than a terrier and smaller than a mastiff.” Watson was surprised. “How you (7 – know) ?”
“I (8 – examine) that stick carefully and (9 – notice) the marks of the dog’s teeth on it,” answered Holmes. “They (10 – be) too broad for a terrier and not broad enough for a mastiff. I suppose the dog often (11– carry) the stick behind its master.It is a spaniel.”
After breakfast Holmes came up to the window. Watson (12 – think) for a second and then asked how he (13 – can) be so sure of that.
“I (14 – be) sure of it because I (15 – see) the dog with its master at our door. I (16 – wonder) why the visitor (17 – want) to see Mr Sherlock Holmes. Well, we soon (18 –find out) !”
