Analyze sentence 1

Using the Modal Verbs of Ability and Contrastive Past and Present knowledge points, we examine the modal verb "can't" in "My wife can't quit smoking." The modal verb "can't" (cannot) is the negative form of "can," which is used to express ability or inability in the present tense. Therefore, this sentence describes present ability.

Analyze sentence 2

Using the Modal Verbs of Ability and Contrastive Past and Present knowledge points, we examine the modal verb "couldn't" in "The old man couldn't breathe." The modal verb "couldn't" (could not) is the past tense negative form of "can," which is used to express ability or inability in the past. Therefore, this sentence describes past ability.

Analyze sentence 3

Using the Modal Verbs of Ability and Contrastive Past and Present knowledge points, we examine the verb in "My neighbor could play the guitar" (partially obscured by the cursor, but clearly "could"). The modal verb "could" is the past tense form of "can," used to express general ability in the past. Therefore, this sentence describes past ability.

Analyze sentence 4

Using the Modal Verbs of Ability and Contrastive Past and Present knowledge points, we examine the modal verb "can" in "I can read books in English." The modal verb "can" is used to express ability in the present tense. Therefore, this sentence describes present ability.
