Now 70 years old, the British physicist, Pendry can’t remember a time when he was not asking a question as a kid, joking that he ________ his parents to death.

 My demand is that the information referred to in my report _____ to Mr. Brown without delay.

He is not native; if he were, we ______ this discussion over his identity.

It was very kind of you to do the washing up, but you _______ it.

As if he ______ my mind，he stood up and offered me his seat when I got on the crowded bus.
