Bike— Part 1 Report

Suggestion: 回答の主旨は伝わりますが、時制の誤り（"I'm/I was"、"can/could"）や言い直しが多く、文が長くつながりすぎています。まず結論を述べ、その後に年齢や上達した時期を2文程度で具体的に説明してください。また、"ride a bike by" は不完全なので、"ride a bike on my own" のように表現しましょう。

Example: Yes, I had a bike when I was a child. I started learning to ride it when I was seven, and by the age of ten, I could ride it on my own. I often rode it around my neighborhood after school.

Suggestion: 最初に意見を述べられていますが、理由の文が不完全で、"car" は複数形の "cars" にする必要があります。"because they are more convenient" のように理由を完成させ、さらに自転車が使われる場面を具体例として加えると、内容が明確になります。"But for the riding a bike?" は不要なので、代わりに対比を示す "However" を使ってください。

Example: No, I don’t think bikes are very popular in Japan. Most people prefer cars or public transportation because they are more convenient for long journeys. However, many people still ride bikes for short trips, such as going to a local shop or train station.

× Yes, I had a bike when I'm I was child and when I was seven years old I started to practice riding a bike and when I turned 10 years old I can I could ride a bike by.

✓ Yes, I had a bike when I was a child. When I was seven years old, I started practicing riding a bike, and when I turned ten, I could ride a bike by myself.

The question asks about your childhood, so you should use the past tense. Use was instead of am and could instead of can because these events happened in the past. When describing a past ability, could is the correct modal verb.

× I started to practice riding a bike.

✓ I started practicing riding a bike.

After start, both the to-infinitive and the -ing form are possible, but started practicing is the more natural expression here. Remember that the verb practice is followed by an -ing form when describing an activity.

× I could ride a bike by.

✓ I could ride a bike by myself.

The phrase by must be followed by a reflexive pronoun when you mean without help. Because the subject is I, use myself: by myself.

× Japanese people prefer car or subway or train or something.

✓ Japanese people prefer cars, subways, trains, or something like that.

The nouns car, subway, and train refer to types of transportation in general, so they should be plural. Use cars, subways, and trains rather than singular nouns.

× Japanese people prefer car or subway or train or something 'cause it is.

✓ Japanese people prefer cars, subways, trains, or something like that because they are more convenient.

The clause because it is is incomplete because it does not state what is convenient. Complete the clause with a subject, a verb, and a complement. Also, use they to refer to the plural transportation options.

× But for the riding a bike?

✓ As for riding bikes, they are not very popular.

Use as for when changing the topic to a particular subject. The phrase for the riding a bike is not natural English. Say riding bikes without the article the before the -ing form when talking about the activity in general.
