Language points
You took part in some volunteer activities during summer holidays, didn’t you
你在暑假参加了一些志愿者活动，是吗？
① 反意疑问句:由两部分构成，前一部分是对事物的陈述，后一部分是简略的问句。前者用肯定形式，后者一般用否定形式；反之亦然。
eg:
It’s a nice day, isn’t it
Ann didn’t use to live there, did she
② join, join in和 take part in，都可表示“参加”:
join多指参加某组织，成为其中的一个成员。
eg: You can join the English club to practice English.
你可以加入英语俱乐部练习英语。
join in 指参加某项比赛或活动，常用于口语。join sb. in (doing) sth.表示“与某人一起参加某种活动”
eg: I hope you'll all join in the discussion.我希望你们大家都参加讨论。
Would you join me in a walk 和我一起去散步好吗
take part in 指参加活动，有时可与join in互换。
eg: Students should take part in all kinds of activities after class.
学生们课后应该参加各种活动。
2. What a wonderful experience!
多么美妙的经历啊！
what引导的感叹句，what意为“多么；真；太”，用作定语修饰名词。
此处句式结构为：
what + a/an + 形容词 + 可数名词单数 + (主语+谓语)！ 口语中常可以省略主语和谓语。
eg: What a new watch (it is)! 多么新的一块手表啊!
3. I have learnt a lot from it.
我已经从中学到了很多。
learn from… 向/从……学习
eg: We should learn from Lei Feng.
我们应向雷锋学习。
learn sth. from sb. 向某人学习做某事或某方面的知识
eg: I’ve learned surfing from him.
我已经向他学习冲浪了。
4. Though I had no time to travel, I still felt happy.
虽然我没有时间去旅行，但我仍然感到很开心。
① though/although 和 even though/even if 意为“虽 然；尽管；即使”，引导让步状语从句，通常不 与but连用。
even though/even if带有强调的意味，语气较强；though和although语气较弱，而thought比although更口语化，不如although正式。
eg: Though/Although it rained, the boys still played outside.
= It rained, but the boys still played outside.
尽管天下雨了，但是那些男孩子仍在外面玩。
② have (no/a little/enough) time to do sth.

eg: He was so busy that he had no time to have lunch.

我总是没有足够的时间来完成作业。
