本题主要考查八年级核心语法现在完成时的用法、词性转换以及固定搭配：
1. 现在完成时的基本结构为“have/has + 动词过去分词”，常搭配already、yet、just、so far等时间标志词；一般过去时常搭配明确的过去时间状语，如last week。
2. 第1题第一空出现have和already，符合现在完成时结构，watch的过去分词为watched；第二空时间状语last week是一般过去时标志，see的过去式为saw。
3. 第2题出现already，是现在完成时标志，主语为I，助动词用have，tell的过去分词为told。
4. 第3题出现have和already，是现在完成时结构，leave的过去分词为left。
5. 第4题是固定句型It's the + 序数词 + time that...，从句需使用现在完成时，主语为I，故填have met。
6. 第5题yet是现在完成时否定句的标志，主语为they，故现在完成时否定形式为haven't read。
7. 第6题just是现在完成时标志，主语my father是第三人称单数，助动词用has，come的过去分词为come。
8. 第7题so far是现在完成时标志，主语为I，故填have seen。
9. 第8题already是现在完成时标志，主语为I，故填have bought。
10. 第9空修饰名词treasure，需将名词culture变为形容词cultural，意为“文化的”。
11. 第10空，chopstick（筷子）为可数名词，日常使用的筷子是成双的，此处表泛指要用复数形式chopsticks。
12. 第11题是固定搭配have no difficulty (in) doing sth.，意为“做某事没有困难”，动词要变为动名词形式expressing。

二、根据中文完成句子。
1. 我已经吃过早饭了。
I had breakfast.
2. 他去过北京两次。
He to Beijing twice.
3. 汤姆去图书馆了(还没回来)。
Tom to the library.
4. 你曾经读过这本书吗？
you this book?
5. 我们还没有把信寄给他们。
We the letters to them .

1. have already
2. has been
3. has gone
4. Have; ever read
5. haven't sent; yet

本题考查现在完成时的相关用法，现在完成时基本结构为“have/has + 动词过去分词”，需区分have been to（去过某地，目前已返回）和have gone to（去了某地，目前尚未返回）的含义，同时掌握already（已经，常用于肯定句）、ever（曾经，常用于疑问句）、yet（还，常用于否定句句末）等标志词的使用：
1. 主语为I，现在完成时助动词用have，“已经”对应already，放在助动词之后，因此填have already。
2. 主语He是第三人称单数，助动词用has，“去过（已返回）”用been，因此填has been。
3. 主语Tom是第三人称单数，助动词用has，“去了未返回”用gone，因此填has gone。
4. 现在完成时的一般疑问句，主语是you，助动词用Have，“曾经”对应ever，“读”的过去分词仍为read，因此依次填Have、ever read。
5. 主语是We，现在完成时否定形式用haven't，“寄”的过去分词是sent，否定句句末的“还”对应yet，因此依次填haven't sent、yet。

三、口语应用。

A. Also, young people don't like them.
B. For showing Chinese brands to the world.
C. And they are really nice and of high quality.
D. I often buy some shoes of Chinese sports brand.
