Error analysis:

error_type: Punctuation Error
error_severity: 1
error_description: ① Punctuation Error: According to English grammar rules, two independent complete sentences 〈It's been two years〉 and 〈two years ago...〉 cannot be connected only by a comma. The connecting comma 〈,〉 needs to be changed to a period 『.』 to achieve correct sentence separation, forming the standard expression 『It's been two years. Two years ago...』. ② Space Error: According to English punctuation rules, a space is needed between a comma and the following word, so a space is added between the comma and 〈two〉 in the original sentence to comply with the norm; ③ Case Error: According to English writing conventions, the first letter after a period must be capitalized. Therefore, the incorrect 〈,two〉 structure is adjusted to 『. Two』 to ensure the basic format requirement of a capitalized first letter after a period.

error_sentence: It happened a lot of things,but all of it are little things.
correct_sentence: A lot of things happened, but all of them were little things.
error: It happened a
correction: A
error_type: Sentence Structure Error
error_severity: 3
error_description: Sentence Structure Error: There is a semantic contradiction when the subject 〈It〉 is paired with the predicate 〈happened〉, as "It happened" is unclear in meaning. According to the intended meaning, the redundant structure 〈It happened 〉 should be deleted and replaced with the specific subject 『A lot of things happened』, which both conforms to the subject-verb structure and accurately conveys the meaning "A lot of things happened".

error_sentence: It happened a lot of things,but all of it are little things.
correct_sentence: A lot of things happened, but all of them were little things.
correction: happened
error_type: Sentence Structure Error
error_severity: 3
error_description: Sentence Structure Error: The original sentence 〈It happened a lot of things〉 has a grammatical error; when "it" acts as a formal subject, it needs to be paired with a specific structure. It is adjusted to the natural word order 『A lot of things happened』, so that the subject 〈things〉 and the predicate 〈happened〉 form a correct subject-verb relationship.

error_sentence: It happened a lot of things,but all of it are little things.
correct_sentence: A lot of things happened, but all of them were little things.
error: it are
correction: them were
error_type: Verb Tense Error
error_severity: 4
error_description: ① Pronoun Error: When a pronoun refers to the plural noun 〈things〉, the plural form should be used. Therefore, the singular pronoun 〈it〉 is changed to the plural pronoun 『them』 to maintain number agreement between the pronoun and its antecedent; ② Verb Tense Error: In the context of describing past events, the linking verb needs to be in the past tense. The present tense 〈are〉 is changed to the past tense 『were』, forming 『things were...』 to maintain tense consistency throughout the text (past time frame).

error_sentence: In 2013,We had PE lesson,In that PE,we had many sport to do,running,rope skiing,Jumping...I was so tired that I fell in a faint.

correction: 2013, we had a
error_type: Determiner Error
error_severity: 4
error_description: ① Space Error: According to English punctuation rules, a comma is used to separate the year from the main clause. The original sentence 〈In 2013,We〉 lacks a space after the comma; it should be corrected to 『In 2013, we』 to ensure a standard space is kept after the punctuation. ② Case Error: According to English writing rules, the first letter after a comma should not be capitalized (unless it is a proper noun). The incorrectly capitalized 〈We〉 is changed to lowercase 『we』, forming the standard format 『In 2013, we』; ③ Determiner Error: As a countable noun phrase, 〈PE lesson〉 requires an indefinite article when first mentioned. Therefore, 『a』 is added before 〈PE lesson〉, forming 『a PE lesson』 to comply with article usage rules.

error_sentence: In 2013,We had PE lesson,In that PE,we had many sport to do,running,rope skiing,Jumping...I was so tired that I fell in a faint.

error_type: Punctuation Error

error_type: Noun Error
error_severity: 2

correction: . Running
error_type: Punctuation Error
error_severity: 3
error_description: ① Punctuation Error: The independent main clause 〈we had many sports to do〉 and the present participle structure 〈running...〉 cannot be connected by a comma. It is changed to a period to separate the two complete structures, i.e., 『...to do. Running...』 to comply with syntactic rules. ② Space Error: According to English written expression norms, a word following a punctuation mark needs to have a space after the mark, so 〈,running〉 should be changed to 『. Running』 to comply with English written expression norms; ③ Case Error: According to English writing rules, the first letter after a sentence should be capitalized. The incorrectly lowercase 〈running〉 is changed to uppercase 『Running』, forming the standard format 『. Running』.

error_type: Noun Error
error_severity: 3
error_description: ① Noun Error: According to sports terminology norms, 〈rope skiing〉 is an incorrect expression; the correct term should be 『rope skipping』 to express the meaning of "jump rope," requiring the entire phrase to be replaced for accuracy. ② Space Error: According to English punctuation rules, a space needs to be kept after the comma between items in a list. The incorrect 〈skiing,Jumping〉 is changed to the standard format 『skipping, jumping』 to ensure a standard space after the punctuation; ③ Case Error: In a list of items, the first letter of a non-proper noun should not be capitalized. The incorrectly capitalized 〈Jumping〉 is changed to lowercase 『jumping』 to maintain format consistency in 『skipping, jumping』.

error_type: Verb Tense Error
error_severity: 3

The incorrect 〈put...to〉 is changed to 『put...on』, forming the standard collocation 『put them on their shoulders』; ② Noun Number Error: The subject 〈they〉 is plural, so the corresponding body part noun needs to be in the plural form. The singular 〈shoulder〉 is changed to the plural 『shoulders』 to ensure number agreement in 『their shoulders』.
