Did you have a bike when you were a child?
Puntuación: 68.0Sugerencia: Answer directly and avoid repeating the time reference: “before” and “when I was a child” overlap. Add one specific detail, such as how you used the bike or what it looked like.
Ejemplo: Yes, I had a bike when I was a child. It was a small red one, and I used to ride it around my neighborhood with my friends.
Do you think bikes are popular in your country?
Puntuación: 52.0Sugerencia: The answer is relevant, but the second sentence has several grammar and word-choice problems. Use “bicycles are a popular form of transportation” and clarify your point about the past. Add a specific reason or example, and connect your ideas with a linking word such as “because.”
Ejemplo: Yes, bicycles are still popular in my country, especially for short trips. They were an important form of transportation before electric vehicles and cars became common, and many people still ride them to save money and avoid traffic.
× Yes, I had a bike before when I was a child.
✓ Yes, I had a bike when I was a child.
Before and when are both used to introduce time clauses, so using them together here is redundant and ungrammatical. Use when to say that you had a bike during your childhood.
× It is one of the transportation used by the people before the electrics and cars built.
✓ It is one of the means of transportation people used before electric vehicles and cars were built.
One of the must be followed by a plural countable noun. Transportation is uncountable, so use a countable expression such as means of transportation. Also, electric vehicles is the appropriate plural noun phrase here.
× It is one of the transportation used by the people before the electrics and cars built.
✓ It is one of the means of transportation people used before electric vehicles and cars were built.
In the original sentence, cars built is missing the auxiliary verb were. The passive past tense requires were + the past participle: cars were built. Use this form when describing cars as having been built.
