本题考查现在完成时中for与since的用法区别：for后面接表示时长的时间段，用来体现动作持续的总时间长度；since后面接过去的具体时间点（如具体年份、特定假期、过去的某一时刻），也可构成"since+时间段+ago"的结构，用来体现动作的起始时间点，二者转换后句子含义保持不变。
1. 空格后five years是时间段，需用for；
2. 空格后the summer vacation of 2025是具体时间点，需用since；
3. 空格后2022是具体年份时间点，需用since；
4. 空格后four weeks ago符合"时间段+ago"的时间点结构，需用since；
5. 空格后several months是时间段，需用for。
1. 空格后five years是时间段，需用for；
2. 空格后the summer vacation of 2025是具体时间点，需用since；
3. 空格后2022是具体年份时间点，需用since；
4. 空格后four weeks ago符合"时间段+ago"的时间点结构，需用since；

My Volunteer Experience
I am a 14-year-old student and I have been a volunteer in the local old people's home for one year. I first went there in last summer vacation, and I have never missed a weekend since then.
The old people there are very lonely, so I often go to talk with them and read newspapers for them. I have told them many interesting stories these months, and they have shared their life experiences with me since I met them. Some of them have not left the old people's home for a long time, so I also help them take a walk in the garden.
My best friend Lucy has joined me in the volunteer work since last September. She is good at singing and she has sung many old songs for the elderly for four months. The old people always clap their hands and smile when they listen to her songs. We have made many friends with the elderly since we started the volunteer work, and we feel very happy to help them.
Volunteering has changed me a lot this year. I have learned to care about others and be thankful for my life. I know I will keep doing volunteer work in the future, because giving is better than receiving.
