1 Unit 1 The Changing World 知识点总结

Topic 1 Our country has developed rapidly.

序 短语/句型 翻译 例句/用法

1 be+adj.+to do sth 做某事很… Kangkang is happy to see his friends.

2 You have just come back from your

hometown. 你刚从你的家乡回来。 此句为“现在完成时”句型,即“have/has+动词过去分词”,此句中,just为现在完成时的标志词,意为“刚刚”。

3 Great changes have taken place in

our hometown. 在我家乡已经发生了巨大的变化。 take place:发生。注意:辨析:take place和happen

take place:指特定情况下的发生,有计划、有安排的发生,其后往往不跟宾语。

happen:指偶然间、碰巧的发生,其后须跟“to”再加宾语。

4 Where have you been? 你去了哪里? been为be的过去分词,have been指去过某地,但目前已经返回。

5 There were so many people that I

couldn’t find a good place to take photos. 那里人非常多以至于我找不到一个拍照的好地方。 ①此句为“so...that…”引导的结果状语从句。

②从句中,动词不定式“to take photos”做定语修饰“place”

6 by the way 顺便问一下

7 She has gone to Cuba to be a

volunteer. 她去了古巴去做一名志愿者。 gone为go的过去分词,have gone指去了某地,并且目前依旧在此地,没有回来。

8 There goes the bell. 铃响了。 此句为倒装句,即主语和谓语颠倒位置。此句中,主语是“the bell”,谓语是“goes”,但此句开头的词语为“there”,是方位副词,故引起主谓倒装。

9 I haven’t seen you for a long time. 我好久没有见到你了。 此句为现在完成时的否定句形式,句中“for+时间段”为现在完成时的标志。

10 You took part in some volunteer

activities during the summer

holidays, didn’t you? 你在假期期间参加了一些志愿者活动,对吗? ①take part in:参加。辨析:take part in和join:

take part in指参加某个具体的项目或者某个会议、聚会

join指加入一伙人或是某个组织、团体、社团。

②此句中“didn’t you”为反义疑问句,反义疑问句由两部分组成,前后两句,前句为肯定句,后句为否定句;反之交换。前后句动词一致,时态一致。

11 What a wonderful experience! 多棒的一次经历啊! 此句为“what”引导的感叹句。强调其后的名词“experience”。experience:①经历(可数)②经验(不可数)

12 learn sth from sth/sb 从某人/某物那里学到… I have learnt a lot from it.

13 Though I had no time to travel, I still

felt very happy. 尽管我没有时间旅行,但是我仍然感觉很开心。 though…still…:尽管….但是仍然….
