Thanks to his pension, Li Zhentian, _____ give each of his grandchildren RMB 5 as a Chinese New year gift for the first time.

The doctor recommended he ____ a few more days in hospital.

I think Tom, as the head of a big department, should either study regularly or______ his job.

Close the door of fear behind you, and you ____ the door of faith open before you.

Thank you very much !
