【分析】
做这类连词成句题，首先根据标点符号判断句子类型（陈述句/疑问句）；其次，结合所给单词的时态（本题均为现在完成时，结构为have/has + 动词过去分词）确定主语、谓语动词；最后按照陈述句语序（主语+谓语+其他）或疑问句语序（一般疑问句将has/have提前，特殊疑问句将疑问词放句首后接一般疑问句语序）排列单词，确保句子语法正确、通顺。
【解析】
1. 标点为句号，是现在完成时陈述句。主语为Tom，谓语是has volunteered，地点状语in the community，时间状语for two years，组合得：Tom has volunteered in the community for two years。
2. 标点为句号，是现在完成时陈述句。主语为My brother，谓语是has worked，地点状语in Beijing，时间状语for three years，组合得：My brother has worked in Beijing for three years。
3. 标点为问号，是现在完成时一般疑问句。将助动词has提前，主语Jim，谓语taken part in，宾语the charity activity，组合得：Has Jim taken part in the charity activity。
4. 标点为句号，是现在完成时陈述句。主语为Our class，谓语是has set up，宾语a volunteer organization，时间状语since 2024，组合得：Our class has set up a volunteer organization since 2024。
5. 标点为问号，是现在完成时特殊疑问句。疑问词How long放句首，后接一般疑问句语序（助动词have提前，主语you，谓语helped，宾语the homeless children），组合得：How long have you helped the homeless children。
【答案】
1. Tom has volunteered in the community for two years
2. My brother has worked in Beijing for three years
3. Has Jim taken part in the charity activity
4. Our class has set up a volunteer organization since 2024

二、请仿照例句，根据图片内容及括号内的提示补充句子。

E.g. Zhao Yu likes working with kids, and she has taught them many interesting games since two
years ago.
6. Wang Min enjoys helping the animal and she
. (last July)
7. Chen Xiao is friendly to the old, and she
. (half a year)
8. Lin Tao's family love nature, and they
. (2023)
9. Zhang Na cares about the environment, and she
. (a few months)
10. Liu Yang wants to help those in need, and he
. (his summer holiday began)

6. has taken care of the animal since last July
7. has helped old people for half a year
8. have planted trees since 2023
9. has sorted waste for a few months
10. has donated books to help since his summer holiday began

【分析】本题考查现在完成时的运用，需结合图片内容确定对应动作，再根据括号内的时间状语（时间点/时间段）判断时态为现在完成时，明确现在完成时结构为“have/has + 动词过去分词”，区分since（接时间点）和for（接时间段）的用法，同时注意主谓一致（主语单数用has，复数用have），最终匹配动作短语完成句子。
【解析】6. 图片对应照顾动物的动作，时间状语last July是时间点，用since，主语Wang Min为第三人称单数，故填has taken care of the animal since last July；
7. 图片对应帮助老人的动作，时间状语half a year是时间段，用for，主语Chen Xiao为第三人称单数，故填has helped old people for half a year；
8. 图片对应种树的动作，时间状语2023是时间点，用since，主语Lin Tao's family为复数，故填have planted trees since 2023；
9. 图片对应垃圾分类的动作，时间状语a few months是时间段，用for，主语Zhang Na为第三人称单数，故填has sorted waste for a few months；
10. 图片对应捐书帮助他人的动作，时间状语his summer holiday began是时间点，用since，主语Liu Yang为第三人称单数，故填has donated books to help since his summer holiday began。
【答案】6. has taken care of the animal since last July
7. has helped old people for half a year
8. have planted trees since 2023
9. has sorted waste for a few months
10. has donated books to help since his summer holiday began
【知识点】现在完成时、动词短语搭配
【点评】本题结合图片情境考查现在完成时的实际运用，既需要准确识别图片表达的行为，又要掌握现在完成时中since和for的用法差异，以及主谓一致规则，是语法知识与识图能力的综合考查。
