不勤奋的英文

Tom is clever but doesn't hard-working

most un-diligent...最不勤奋

Tom is smart but not hardworking.

inexertion

You are not diligent，neither is he.They are as diligent as you.In this accident,more than 20 children were injured.

Tom is smart but does not work hard. work hard 勤奋的是意思。 Tom 后加了is因为smart是形容词。 而work hard前面加does 因为work是动词， 而且Tom是第三人称单数， 所以用does. does后面加动词原形。
