Do you know why the teacher asks for me ? — He wants you to _____ your absence last night.

simply couldn’t understand how it _____ that you did so much work within such a short time．

With the speedup of the railway, now you can get to your destination by train.

This is the only way we can think of _____the problem. [ ]

have just had my watch repaired.—How much did they ______ you?
