Look! People are hurrying along the street with collars and umbrellas
up. It must (be raining) hard. 2. Peggotty enclosed the half-guinea in the
letter; I was afraid she must (have had) a world of trouble to get it out
of Mr. Barkis's box. (CD.) 3. You must (follow) my advice. There is
no other way out for you. 4. I saw an old woman sleeping soundly in
Green Park. A shower was falling at the time, she must (have been) drenched
to the skin. (Ldn) 5. All time we were out the two gentlemen smoked
incessantly — which, I thought, if I might judge from the smell of their
rough coats, they must (have been doing) ever since the coats had first come home
from the tailor's. 6. "The hotels must (have done) a tremendous business,"
old Jolyon thought. "A few years ago there had been none of these big
hotels." Then he thought of his son. "... If Jo were only with him. The
boy must (be) forty by now." (Gls.) 7. She must (be) angry with
you. She does not even look in your direction. 8. She must (have got)
angry with me. She left without saying good-bye. 9. Mary must (have been)
ill, otherwise she would have come. 10. Mary must (have fallen) ill. She
looked so pale and tired last night.
