A
Every year, a small number of travellers choose to spend part of their holiday doing something truly meaningful. In Tortuguero, a quiet coastal area(沿海地区) in Costa Rica, visitors can join a sea turtle protection project. When they first arrive, many are unsure of 21 during the programme—the schedule looks complex and the rules are strict. Luckily, experienced guides are always nearby to explain everything clearly.
The project 22 volunteers from over forty countries since it started, and its impact on local turtle populations(龟群数量) has been significant. Each night, volunteers walk along the beach in the dark, watching carefully for turtles that come ashore to lay their eggs. 23 rewarding it feels to protect a nest(巢穴) and know that dozens of baby turtles may one day hatch safely because of your effort! If you join the project next summer, you 24 come back with a completely new understanding of what travel can mean. Volunteers often say they spent their evenings 25 under the stars, thinking quietly about the natural world around them.
()21. A. where to go B. where going C. where they go
()22. A. attracts B. attracted C. has attracted
()23. A. What B. How C. What a
()24. A. will B. would C. should
()25. A. to sit B. sitting C. sit

21. A 22. C 23. B 24. A 25. B
点拨:21题,A. where to go,“wh-词+不定式”结构,意为“去哪里”,作介词of的宾语,是Unit 3本单元核心语法点。B. where going 缺少不定式符号to,不符合语法;C. where they go 为宾语从句,语法上可行但空前已有unsure of,后接宾语从句时应用疑问词引导从句(where they should go),而“wh-词+不定式”更简洁自然,而且是本单元重点考查结构,故选A。
27题,A. Although,让步状语从句,意为“尽管一些旅行者起初感到困惑……大多数人表示……”,前后分句形成让步关系,让步逻辑清晰。B. Because表原因,与后半句“most say the experience move them”逻辑矛盾;C. If表条件,句意不通。
30题,C. those of,those of引导比较结构,ways of life that are different from those of your own,those指代上文ways of life,避免重复,是比较句中的标准省略替代。此题为反考:学生可能直接选A. that(that of your own),但that只能替代单数名词,ways为复数,故必须用those;B. which为关系代词,不能在此处引导比较结构。

【分析】
本题为英语完形填空单项选择题，主要考查初中英语基础语法，包括疑问词+不定式结构、现在完成时、感叹句、条件状语从句时态、固定搭配等。解题时需结合语境和语法规则逐一分析选项，确定正确答案。
【解析】
21题：考查疑问词+不定式作宾语的结构。句中unsure of后需接宾语，"疑问词+不定式"（where to go）可作介词of的宾语，符合语法；B选项where going缺少不定式符号to，结构错误；C选项宾语从句需调整为where they should go才符合语境，且不如不定式简洁，故选A。
22题：考查现在完成时。句中since引导时间状语，主句需用现在完成时，结构为"has+过去分词"，主语the project为单数，故用has attracted，选C。
23题：考查感叹句。感叹句中，形容词rewarding前需用How，结构为"How+形容词+主语+谓语"，故选B。
24题：考查条件状语从句的时态。if引导的条件状语从句遵循"主将从现"原则，从句用一般现在时，主句需用一般将来时will，故选A。
25题：考查固定搭配。spend time (in) doing sth为固定搭配，意为"花费时间做某事"，故用sitting，选B。
