自行车— Part 1 评分报告

建议: Be concise and grammatically accurate. Start with a direct topic sentence, then give 1–2 specific supporting details using correct tense and word order. Avoid repetition and unfinished clauses. Use linking words (e.g. "because", "so") correctly and finish your thought.

示例: Yes, I had a bicycle when I was a child. My father bought it for me and I learned to ride it over about six months. However, when my younger sibling arrived, he often damaged the bike, so I stopped using it as much.

建议: Give a clear topic sentence, then support it with 1–2 specific reasons and examples. Use plural/singular agreement and complete sentences. Use linking words like "because", "for example" and finish explanations (e.g. explain what happens after scanning a code).

示例: Yes, bikes are very popular in China because they are inexpensive and convenient. For example, shared bike services are widespread: you can scan a QR code on a bike to unlock it and ride to your destination, which makes short trips fast and affordable.

× I really had a bike which bought by my father

✓ I really had a bike which was bought by my father

The phrase 'bought by my father' needs a passive construction with the past participle 'bought' and the auxiliary 'was' to form the past passive. Use 'was bought' because the bike is the object that received the action in the past. Suggestion: include the appropriate form of 'be' (was) before the past participle for passive voice.

× and I studied ride a bike for about half a year

✓ and I learned to ride a bike for about half a year

The verb phrase 'studied ride' is incorrect. English uses 'learned to ride' or 'practiced riding' to express acquiring the skill. Use 'learned to ride' for acquiring ability, or 'practiced riding' if emphasizing repeated action. Also 'for about half a year' correctly indicates duration.

× But when my sibling came my home and he was a very naughty boy and he.

✓ But when my sibling came to my home, he was a very naughty boy.

The sentence is ungrammatical and incomplete. 'Came my home' needs the preposition 'to': 'came to my home.' The trailing 'and he.' is a fragment and should be removed or completed. Combine clauses properly and end with a full clause. Suggestion: remove the extra 'and he' and add commas as needed.

× Yeah, because bike is cheap and a very convenient.

✓ Yeah, because bikes are cheap and very convenient.

The noun 'bike' should be plural ('bikes') when making a general statement about them. Also use the plural verb 'are' to agree with plural subject. The article 'a' before 'very convenient' is incorrect with a plural subject; remove it. Suggestion: use plural noun and matching verb for general statements.

× So I think bikes are very popular in China.

✓ So I think bikes are very popular in China.

This sentence is grammatically acceptable; no article change is needed. It is included here to indicate no correction required; keep as is.

× Of course, because you can and there are many, umm, shared bikes in the streets.

✓ Of course, because there are many shared bikes on the streets, you can easily use one.

The original sentence is disfluent and missing a main clause after 'because you can'. 'There are many shared bikes on the streets' is better phrased with the preposition 'on' for streets. Add a main result clause ('you can easily use one') to complete the thought. Suggestion: avoid leaving 'because you can' unfinished and use 'on the streets' for location.

× When you scan the code, you can.

✓ When you scan the code, you can unlock and ride a shared bike.

The clause 'you can' is incomplete and needs an object or verb phrase to indicate what is possible. Provide the action that follows scanning the code, e.g., 'unlock and ride a shared bike.' This completes the conditional clause. Suggestion: always complete 'can' with the verb phrase that follows.
