Habits expressed by will and would

Habits in the present are normally expressed by the Present Simple. But, among other uses of the Future Simple, will + infinitive can be used instead when we wish to emphasize the characteristics of the performer rather than the action performed. It is chiefly used in general statements:

"An Englishman will usually show you the way in the street. "(It is normal for an Englishman to act in this way.)
"She will always greet you."

1.Past routines

This is not a very important use of will, but the past form, would, has a much wider use and can replace used to when we are describing a past routine:

On Sundays he used to/would get up early and go fishing. He used to/would spend the whole day by the river and in the evening used to/would come home with marvellous stories of the fish he had nearly caught.

Note, however, that when used to expresses a discontinued habit, it cannot be replaced by would. Both will and would can be contracted when used as above.

2. Will can also express obstinate insistence, usually habitual:

Example: "If you will keep your watch half an hour slow it is hardly surprising that you are late for your appointments."

Would is used in the past:
Example: "We all tried to stop him smoking in bed but he would do it."

3. Would can express a characteristic action, usually one which annoys the speaker:

Bill objects/objected. ~ He would object! (He always objects.)
