1.Rita,you have just come back from your hometown.丽塔，你刚从老家回来。

该句使用的是现在完成时的肯定式，由“主语+have/has+动词的过去分词+其他”构成。现在完成时表示过去发生的某一动作对现在造成的影响或结果。其结构是：“助动词have/has+动词的过去分词”。

动词过去分词的构成：规则变化跟动词的过去式一样，不规则变化见教材后面的附表。【拓展】（1）否定句：“主语+haven’t hasn't+动词的过去分词+其他”.如：

Tom hasn't seen this film.汤姆没看过这部电影。

（2）一般疑问句：“Have/Has+主语+动词的过去分词+其他？”。如：

Have you cleaned the classroom?你打扫教室了吗？

（3）特殊疑问句：“特殊疑问词+have/has+主语+动词的过去分词+其他？”。如：

Where has John gone?约翰去哪儿了？,

2.Great changes have taken place there and my hometown has become more and more beautiful.那里发生了巨大变化，我的家乡变得越来越美。

take place意为“（尤指根据安排或计划）发生，进行”。如：

The art festival will take place on October 1st.艺术节将于10月I日举行。

【链接】happen意为"（尤指偶然）发生，出现”。如：

You'll never guess what has happened.你根本猜不刻出了什么事。

【拓展】take the place of sb./sth.意为“代替，留换",相当于take sb.'s/sth.'s place。如：

I have to find someone to take Jenny's place. She's badly ill.我得找个人代替珍妮，她病得很重。

3.But there were so many people that I couldn't And a good place to take photos.但是人太多，我找不到一个拍照的地方。

so...that...意为“如此……以至于……”，引导结果状语从句。常用结构：so+adj./adv.+that..." 。如：

The man is so lazy that he does badly in almost everything.这个人是如此的懒，以至于他几乎什么事情都做不好。

【链接】such...that...意为“如此……以至于……”,引导结果状语从句。其结构为“such+（a/an）+（adj.）+n.+that..."。如：

Tom is so cute that everyone likes him.汤姆很可爱以至于每个人都喜欢他。

【拓展】但当名词前有many,much,few,little等词修饰时，只能用so...that...,如：

The man has so little money that he has to find a job as quickly as possible.这个人几乎没有钱了，以至于他必须尽快找个工作。

4.There goes the bell.铃响了。

本句为倒装句。通常情况下，在以here,now,there,then等副词开头的句子里，当谓语动词是be,come,go,follow等词，主语又是名词时，需要把谓语动词置于主语之前，构成完全倒装。如：

Now comes your turn,现在轮到你了。

【注意】若主语是代词则不用完全倒装。如

Here he comes.他来了。

【拓展】go表示发出某种声音，可指警告声或提示音。如：

The gun went "bang”.枪"砰”的一声响了。
