1. Jim started learning Chinese four years ago.
In this sentence, we are talking about an action that began in the past (four years ago) and is still relevant in the present (Jim is still learning Chinese). Therefore, we need to use the present perfect tense. The correct form of the verb "start" in the present perfect tense is "has started." So the correct sentence is "Jim has started learning Chinese four years ago."
2. My brother borrowed a camera from a friend last week.
In this sentence, we are talking about an action that happened and completed in the past (last week). There is no connection to the present, so we need to use the past simple tense. The correct form of the verb "borrow" in the past simple tense is "borrowed." So the correct sentence is "My brother borrowed a camera from a friend last week."
3. We made sandwiches for the journey.
In this sentence, we are talking about an action that happened and completed in the past. Again, there is no connection to the present, so we need to use the past simple tense. The correct form of the verb "make" in the past simple tense is "made." So the correct sentence is "We made sandwiches for the journey."
