Dic: Rather than and would rather

자료: http://www.perfectyourenglish.com/usage/rather-than.htm

Rather than is normally used in parallel structures: for example with two adjectives, adverbs, nouns, infinitives or -ing forms. When the main clause has a to-infinitive, rather than is normally followed by an infinitive without to. An -ing form is also possible.

• I would prefer to leave now rather than wait.
• You ought to admit your crime rather than defend it.
• I would prefer to go in August rather than in July.
• I decided to write rather than phone/phoning. (NOT …than to phone)

Would rather

Would rather means 'would prefer to'. It is followed by an infinitive without to.

• Would you rather stay here or go home? (=Would you prefer to stay here or go home.)

Would rather + subject + past tense

We can use would rather to say that one person would prefer another or others to do something. We use a special structure with a past tense.

• Don’t come today, I would rather you came tomorrow. (=I would prefer you to come tomorrow.)
• I would rather you posted this letter. (= I would like you to post this letter.)

To talk about past actions, a past perfect tense is possible.

• I would rather you hadn't done that. (= I wish you hadn't done that.)
