Error analysis:

correction: am
error_type: Verb Choice Error
error_severity: 4
error_description: ① Auxiliary Error: According to English grammar rules, the original sentence 〈Today,I with my family go to shop.〉 intends to express a present state but lacks an auxiliary verb. In the present tense, with the first-person subject “I”, the auxiliary verb 『am』 needs to be added after 〈I〉 to form the “am with” structure, fully expressing the current state; ② Verb Choice Error: In the original sentence 〈I with my family go〉, “with my family” is an adverbial phrase of accompaniment, and the sentence lacks a suitable predicate verb to reflect the state of the subject “I”. Considering the context, 『am』 should be used to indicate the subject's current state, making the sentence structure complete and the meaning clear.

error_sentence: Today, I with my family go to shop.
correct_sentence: Today, I am with my family at the shop.
error: go to
correction: at the
error_type: Preposition Error
error_severity: 3
error_description: ① Preposition Error: According to English expression conventions and the picture's scene (at the mall), the original phrase 〈go to〉 indicates direction of movement, whereas the sentence needs to express location. It should be replaced with 〈at the〉; 〈at the shop〉 is the correct way to express the location; ② Determiner Error: In English, “shop” as a specific place requires the definite article 〈the〉 to specify the object. Therefore, 〈the〉 needs to be added before 〈shop〉 in the original sentence for accurate and standard expression.

error_sentence: A young lady ia looking at a dress.
correct_sentence: A young lady is looking at a dress.
error: ia
correction: is
error_type: Spelling Error
error_severity: 2
error_description: Spelling Error: According to English grammar rules, in the present continuous tense structure “be + present participle”, the linking verb 〈ia〉 in the original sentence is misspelled; the correct spelling should be 『is』. 〈ia〉 needs to be changed to 『is』 to form “is looking”, making the sentence conform to the present continuous tense rules and accurately express the meaning “A young lady is looking at a dress”.

error_sentence: My mother is trying the shoes.
correct_sentence: My mother is trying on the shoes.
correction: on
error_type: Preposition Error
error_severity: 3
error_description: Preposition Error: According to English fixed phrase rules, “try on” is the fixed phrase meaning “to try clothes/shoes on”. The original sentence “My mother is trying the shoes.” lacks the preposition 〈on〉 and cannot accurately express the action of “trying on”. 〈on〉 should be added after 〈trying〉, changing “trying the shoes” to “trying on the shoes”, making the expression conform to English semantics and grammar rules.
