Yes, because mostly of the children I hear are using bike. Sometimes they use it in the work.
Did you have a bike when you were a child?
分数: 55.0建议: Answer directly and use the past tense because you are talking about childhood: change “have” to “had.” Add one specific detail, such as where you rode the bike or who gave it to you.
示例: Yes, I had a bike when I was a child. It was a small red one, and I often rode it around my neighborhood with my friends.
Do you think bikes are popular in your country?
分数: 40.0建议: State clearly who uses bikes and give a relevant reason or example. Use “most children” rather than “mostly of the children,” and say “ride bikes” or “use bikes to get to work” instead of “use it in the work.”
示例: Yes, I think bikes are quite popular in my country, especially among children and people who live near their workplaces. For example, many children ride bikes to school, while some adults cycle to work because it is convenient and inexpensive.
× Yes, I have a bike when I was a child.
✓ Yes, I had a bike when I was a child.
The phrase when I was a child refers to a completed period in the past, so the verb should also be in the past tense. Use had, the past tense of have.
× Yes, because mostly of the children I hear are using bike.
✓ Yes, because most of the children I hear are using bikes.
Use most of, not mostly of, before a noun phrase to refer to the majority of a group. Mostly is an adverb and does not fit this structure.
× Yes, because mostly of the children I hear are using bike.
✓ Yes, because most of the children I hear are using bikes.
The sentence refers generally to bikes used by multiple children, so the plural form bikes is appropriate. Use a plural noun when speaking about bikes in general.
× Sometimes they use it in the work.
✓ Sometimes they use them for work.
For work is the natural prepositional phrase when describing the purpose of using something. In the work is not appropriate in this context. Them agrees with the plural noun bikes.
