How much do you know about Easter?
复活节的由来
复活节是基督教纪念耶稣复活的一个宗教节日。每年，春分过去，第一次月圆后的第一个星期日就是复活节。日期年年不同，一般在3月22日至4月25日之间。
复活节有不少传统习惯，最典型的要数复活节彩蛋。古人常把蛋视为多子多孙和复活的象征。后来基督教徒又赋予蛋新的涵义，认为它是耶稣墓的象征，未来的生命就是从其中挣脱而出世的。

How Do You Use the Internet?PPT，第三部分内容：知识讲解
it is easy to carry它容易携带
“主语＋be＋形容词＋动词不定式．”中动词不定式与主语有时是主谓关系，有时是动宾关系。可与it作形式主语的句子转换。
eg：English is easy to learn .
＝It’s easy to learn English .
学英语是容易的。
The problem is difficult to solve .
＝It’s difficult to solve the problem .
解决这个问题很困难。
Volleyball is interesting to watch .
＝It’s interesting to watch volleyball .
看打排球很有意思。
She’s very nice to talk to .
＝It’s very nice to talk to her . 和她谈话是很愉快的。
It’s necessary for us ________ to our parents when we have problems. (长沙改编)
A．to talk B．talking
C．talk D．talks
【点拨】采用分析句子结构法。to talk是动词不定式形式；talking 谈话，动名词形式；talk谈话，动词原形。这句话中使用的句型是It is ＋形容词＋for sb . to do sth . 对于某人来说做某事是……的。由此可知，这里应用动词不定式形式。
invitation/ֽɪnvɪ'teɪʃn/ n．邀请；请帖
eg：Thank you for your invitation .
谢谢你的邀请。
We had three invitations to parties .
我们有三封聚会的请帖。
invite v.邀请，常用的结构：
invite sb . 邀请某人
I invited all my friends.
我邀请了我所有的朋友。
invite sb . to do sth .
