互動一：單詞記憶比賽
互動二：對話熟讀接力賽
互動三：分角色表演對話
互動四：知識點展示大比拼
知識點一：Have you ever been to the zoo?
【詞語辨析】have gone to、have been to、have been in 的區(qū)別和用法
?。?）? have gone to意為“到某地去”，說話時該人不在現(xiàn)場，一般不用第一人稱、第二人稱代詞作句子的主語。
如：-Where is Jim？---吉姆在哪里？
-He has gone to England.---他去英國了。（
4、尚未回來）
Mr Wang isn't here.He has gone to Qingdao.王先生不在這里。他去青島了。
（2） have been to意為“曾經(jīng)去過某地”，現(xiàn)在已不在那里了，后可接次數(shù)，如once，twice，three times等，表示“去過某地幾次”，也可和 just，never，ever等連用。如：
My father has been to Beijing twice.我父親去過北京兩次。
I have never been to the GREat Wall.我從未去過長城。
?。?） have been in表示“在某地呆了多少
5、時間”，常與時間段狀語連用。如：
I have been in Shanghai for three years.我到上海已有三年了。
He has been in London for half a month.他來倫敦已有半個月了。
知識點二：Then don't take photos of me.
Take photos 為固定詞組，意為“照相”，相當(dāng)于take pictures，也可表示為take a photo;
take photos/a photo of sb.意為“給某人照相”
Eg: He took many photos of his
6、mother.
知識點三：Maybe photos would surprise the animals.
【詞語辨析】maybe/may be
?。?） Maybe是副詞，表示“大概，或許”，用來表示猜測，在句中作狀語，常用于句首，相當(dāng)于perhaps
Eg:Maybe he doesn't know it's spring.
Maybe you put the letter in your pocket.
?。?） May be情態(tài)動詞may和系動詞be一起也可以表示“可能是…”
Eg:You may be right.
I can't find
7、 my watch. It may be in your pocket.
知識點四：It's nearly noon,and he's still sleeping.
nearly是副詞，意思是? 幾乎，差不多。
Eg:Hurry up--it's nearly time for school.
nearly和almost都表示? 幾乎，差不多。在多數(shù)情況下，兩者之間沒有什么差別。
一般來說almost所表達(dá)的程度比nearly更接近一些。
另外，nearly不能用于修飾否定詞，但可被not修飾，not nearly 意為“遠(yuǎn)不如”;
而almost可以和否定詞連用。
知識點五：That's where we go out.
where we go out.是表語從句，where是引導(dǎo)詞。這樣的詞還有：wh-,that,because等。如：That's what he said.
That's why I am so worried.
The question is whether our parents will agree.
The problem is which is heavier.
