二、用括号内所给单词的适当形式填空。
1. Mum (make) me a new coat yesterday. I (try) it on already. It fits me well.
2. There (be) great changes in my hometown in the past twenty years.
3. Sam (learn) Chinese since he came to China. He speaks Chinese very well now.
4. This is the best TV play that I (watch) these years.
5. My family (be) to many interesting places in the last few years.

1. made; have tried 2. have been 3. has learned/has learnt 4. have watched 5. have been

本题考查一般过去时和现在完成时的用法：
1. 第一空时间状语yesterday表示过去的时间，要用一般过去时，make的过去式为made；第二空出现标志词already，强调过去动作对现在的影响，要用现在完成时，主语为I，对应的结构是have tried。
2. 时间状语in the past twenty years是现在完成时的标志，主语great changes为复数，there be句型的现在完成时结构为have been。
3. 句中since引导时间状语从句，是现在完成时的典型标志，主语Sam是第三人称单数，对应的结构为has learned/learnt。
4. 时间状语these years表示从过去到现在的时段，先行词被最高级the best修饰，语境强调到目前为止的经历，用现在完成时，主语为I，结构为have watched。
5. 时间状语in the last few years是现在完成时的标志，此处my family指代家庭成员，表复数概念，have been to表示“去过某地”，符合语境。

三、根据汉语提示完成句子。
1.经验丰富的志愿者们教我如何组织慈善活动。
The experienced volunteers me how charity events.
2.你在动物收容所当志愿者多久了？
have you a volunteer at the animal shelter?
3.自从去年年初开始，汤姆就一直把自己的一部分零花钱存下来。
Tom ______ ______ part of his pocket money ______ the beginning of last year.
4.自从这个项目启动以来，我们已经为那些需要帮助的人建造了二十座新房子。
the project started, we twenty new houses for those in need.
5.看到孩子们快乐的笑容，我们所有的辛勤付出都值得了。
Seeing the children's happy smiles all our hard work it.

1. teach/taught; to organize
2. How long; been
3. has been saving; since
4. Since; have built
5. makes; worth

本题考查八年级核心的动词搭配、疑问词+不定式结构、现在完成/现在完成进行时等知识点：
1. 第一空“教”可填teach（一般现在时）或taught（一般过去时）；“疑问词how+不定式”是固定结构，作宾语，“组织”对应动词organize，后两空用to organize符合结构和语义。
2. 对动作持续的时长提问用固定疑问词组How long；句子为现在完成时，结构是have+动词过去分词，“当志愿者”用be a volunteer，be的过去分词是been，第三空填been。
3. 由“自从去年年初、一直”可知动作从过去持续到现在仍在进行，用现在完成进行时结构has/have been doing，主语Tom是第三人称单数，前两空填has been saving；表示“自从（过去时间起点）”用since，第三空填since。
4. 引导时间状语从句、表示“自从”用Since，主句动作从项目启动持续到现在，用现在完成时，“建造”的过去分词是built，后两空填have built。
5. 动名词作主语时谓语动词用单数，“使、让”用makes；固定搭配worth it表示“值得”，符合“所有辛勤付出都值得”的语义。
