Error analysis:
error_sentence: He learnt so hard that he could learn something by heart.
correct_sentence: He studied so hard that he could learn something by heart.
error: learnt
correction: studied
error_type: Verb Choice Error
error_severity: 3
error_description: Verb Choice Error: According to the context, the sentence here means 'to study', expressing the act of 'studying hard'. In the original sentence, 〈learnt〉 means 'to have acquired knowledge', which does not fit the meaning. Therefore, 〈learnt〉 needs to be changed to 『studied』 to fit the context.
error_sentence: He was so smart that he could solve who had difficult problems.
correct_sentence: He was so smart that he could solve difficult problems.
error: who had
error_type: Word Redundancy Error
error_severity: 5
error_description: ① Relative Word Error: According to the context, the meaning here is 'solve difficult problems'. The original phrase 〈who had difficult problems〉 has no clear referent semantically, so 〈who had〉 needs to be deleted to clarify the meaning; ② Word Redundancy Error: According to the context, 『solve difficult problems』 directly expresses 'solve difficult problems'. In the original sentence, 〈who had〉 is a redundant component, so it needs to be deleted to make the sentence more concise and semantically clear.
error_sentence: He spent three years studying in French.
correct_sentence: He spent three years studying French.
error: in
error_type: Preposition Error
error_severity: 2
error_description: Preposition Error: According to English expression habits, when expressing 'studying a certain language', the preposition 〈in〉 is not needed. In the original sentence 〈studying in French〉, 〈in〉 expresses location rather than language, so it needs to be changed to 『studying French』 to correctly express the semantics of studying a language.
error_sentence: And he often was invited to make a speech for people at the other universities.

correct_sentence: And he was often invited to make a speech at other universities.

error: often was
correction: was often
error_type: Word Order Error
error_severity: 4
error_description: Word Order Error: According to English word order rules, the adverb 〈often〉 should be placed after the auxiliary verb 〈was〉. Therefore, 〈often was〉 is adjusted to 『was often』 to comply with English word order rules.
error_sentence: And he often was invited to make a speech for people at the other universities.

correct_sentence: And he was often invited to make a speech at other universities.

error: for people at the
correction: at
error_type: Word Redundancy Error
error_severity: 5
error_description: ① Word Redundancy Error: According to the context, 『make a speech at other universities』 directly expresses 'to give a speech at universities'. In the original sentence, 〈for people〉 is a redundant component, so it needs to be deleted to make the sentence more concise and semantically clear; ② Determiner Error: According to English grammar rules, the definite article 〈the〉 indicates specificity, but it is not needed when referring to universities in a general sense. Therefore, the original phrase 〈at the〉 is modified to 『at』 to comply with grammar rules.
error_sentence: In my opinions,I help my classmates to look like him.
correct_sentence: In my opinion, I help my classmates to be like him.
error: opinions
correction: opinion
error_type: Noun Number Error
error_severity: 2
error_description: Noun Number Error: According to English grammar rules, the original word 〈opinions〉 should be in the singular form 『opinion』 to be consistent with expressing only one viewpoint in the context; therefore, 〈opinions〉 should be changed to 『opinion』 to comply with English grammar rules.
error_sentence: In my opinions,I help my classmates to look like him.
correct_sentence: In my opinion, I help my classmates to be like him.
error: look
correction: be
error_type: Verb Choice Error
error_severity: 3
error_description: Verb Choice Error: According to the context, the sentence here means 'to be a person like him'. In the original sentence, 〈look like〉 emphasizes physical resemblance, which does not fit the meaning. Therefore, 〈look like〉 needs to be changed to 『be like』 to fit the context.
error_sentence: I admire him learning attitude.
correct_sentence: I admire his learning attitude.
error: him
correction: his
error_type: Pronoun Error
error_severity: 2
error_description: Pronoun Error: According to the meaning of the sentence, the intention here is to express 'his' to modify the noun 〈learning attitude〉. In the original sentence, 〈him〉 cannot modify a noun phrase. Therefore, 〈him〉 is changed to 『his』 to indicate possession and fit the context.
error_sentence: Let's study hard to look like him,shall we?
correct_sentence: Let's study hard to be like him, shall we?
error: look
correction: be
error_type: Verb Choice Error
error_severity: 3
error_description: Verb Choice Error: According to the context, the sentence here means 'to be a person like him'. In the original sentence, 〈look like〉 emphasizes physical resemblance, which does not fit the meaning. Therefore, 〈look like〉 needs to be changed to 『be like』 to fit the context.
