Bike— Part 1 採点レポート

提案: 回答は短くて内容は伝わりますが、文法とつながり（cohesion）が改善できます。具体的には、断片的な文（"In my childhood."）を完全な文章に直し、主題文の後に理由や具体例を付け加えて会話を豊かにしましょう。接続詞（for example, so, because, and）を使って文をつなぎ、語彙を少し広げて自然な表現にしてください。発音や流暢さが問題でなければ、文の長さを2〜4文に収めると効果的です。

例: Yes, I had a bike when I was a child. I used to ride it to the park after school to play with my friends, and sometimes we would race each other on the paths. It was my main way to get around because my house was close to the park.

提案: 考えは伝わりますが、語彙の選択と文の流れを改善する必要があります。"I think so"は曖昧なので、はっきりとした主張文で始め、理由を2つ程度挙げて具体例や比較を加えると良いです。また "flat prices" は不自然な表現なので、正しい語彙（e.g. affordable, low cost）を使いましょう。接続詞（because, moreover, for example）で文をつなげ、より自然で説得力のある回答にしてください。

例: Yes, bikes are quite popular in my city. Many people use them because they are affordable and convenient for short trips, and the streets are relatively flat which makes cycling easy. For example, I see commuters riding to work every morning, especially during rush hour.

× Yes, I had a bike. In my childhood.

✓ Yes, I had a bike in my childhood.

The second fragment 'In my childhood.' is a sentence fragment lacking a clear connection; it should be combined with the previous sentence to form a complete sentence: 'Yes, I had a bike in my childhood.' This provides a single complete idea and correct sentence structure. Suggestion: combine fragments into one sentence or add a verb to make the fragment independent.

× There are a lot of people using bikes in my city.

✓ There are a lot of people who use bikes in my city.

The original uses a present-participial clause 'using bikes' which is grammatical but less natural in this context. Replacing it with a relative clause 'who use bikes' makes the meaning clearer and matches common usage. Suggestion: use 'who use' for habitual actions by people.

× It's convenient and flat prices.

✓ They are convenient and prices are low.

The phrase 'flat prices' is incorrect here: 'flat' is an adjective that does not collocate with 'prices' to mean inexpensive; additionally 'It' is singular while referring to two ideas (convenience and prices). The correction separates ideas and uses 'prices are low' to convey affordability. Suggestion: match subjects and adjectives properly and use common collocations like 'low prices'.
