【分析】
本题为汉译英默写题，解题思路如下：1. 先判断句子时态：描述过去的动作用一般过去时，描述现在的状态/动作用一般现在时，疑问句需注意语序；2. 匹配中文对应的英语固定短语，如“给家人和朋友写信”对应write letters to my family and friends，“花费时间在...”对应spend time on sth等；3. 注意动词过去式变形（如write→wrote、spend→spent等）；4. 时间状语（如In the past、Two weeks ago）通常放句首，疑问句以情态动词/助动词开头。
【解析】
1. 时间状语“In the past”提示用一般过去时，“给家人和朋友写信”是write letters to my family and friends，write的过去式为wrote，故译为In the past, I wrote letters to my family and friends.
2. 时间状语“then”提示用一般过去时，“花费大量时间在路上”是spend a lot of time on the road，spend的过去式为spent，故译为We spent a lot of time on the road then.
3. 时间状语“Two weeks ago”提示用一般过去时，“从商店买机器人”是buy a robot from a shop，buy的过去式为bought，故译为Two weeks ago, Bobby's parents bought a robot from a shop.
4. 时间状语“Twenty years ago”提示用一般过去时，“去商店并用现金付款”是go to shops and pay in cash，go的过去式为went，pay的过去式为paid，故译为Twenty years ago, I went to shops and paid in cash.
5. 时间状语“Now”提示用一般现在时，“高铁运行非常快”对应high-speed trains travel very fast，故译为Now high-speed trains travel very fast.
6. 为情态动词开头的一般疑问句，“你们能告诉我关于...吗”是Can you tell me about...，“生活中的变化”是the changes in your life，故译为Can you tell me about the changes in your life?
7. 时间状语“Now”提示用一般现在时，“和他们在网上聊天”对应chat with them on the internet，故译为Now I chat with them on the internet.
8. 时间状语“These days”提示用一般现在时，“居家办公”是work from home，“开线上会议”是have online meetings，故译为These days, I sometimes work from home and have online meetings.
