达标拓展:
…,the dog got out of the box and ran away ----.只狗冲出了箱子跑掉了。
Run away 意为“逃跑，跑开”，away 为副词，意为“离开，远离”。
He was jumping and running with another dog.正和另一只狗跑着跳着。
1 another 此处作形容词，意为“另一，再一，别的”通常作定语。
如：There is another seat。I can’t sit over there。还有一个座位，我可以坐那边。
2 another 还可作代词，意为“又一个，再一个”，表示三者或三者以上中的另一个。
如：I don’t like this pen .lease show me another.不喜欢这只钢笔，请再给我拿一只看看。
3 another 后常接单数名词或代词，常有“another+基数词+名词复数”的形式，意为“另外几个，再有几个”，与“基数词+more+名词复数“同义。
如：“我想再买两本书”。可表达为：I want to buy another two books. I want to buy two more books.
这双鞋子太大了，我还想要另外一双。The shoes are too big ，so I’d like to try a_______pair。
What happened while Linda was on the telephone？当琳达打电话时，发生什么事了？
1 happen为动词，意为“发生，偶然发生”，常指具体事件的发生，特别指那些偶然的或未能预见的事件的“发生”。 主语常为“事或物”。如：
A bad traffic accident happened yesterday.昨天发生了一起严重的交通事故。
2 如果表示“某人发生某事”，常用结构“某事+happened（s）+to +某人。”如：
What happened to her ？她怎么了？
3 sb happened to do sth“某人碰巧做某事”。如：
I happened to meet my English teacher on my way to school.在上学的路上我碰巧遇见了我的英语老师。
take place /happen
二者都表示“发生”，都是不及物动词，所以不用被动语态。而且两者都是短暂性动词，不能与“一段时间”的状语连用。
Take place表示按照预先计划、安排某事发生。
Happen 往往表示偶然性的、没有预料的事情“突然发生”。
如：The May 4th Movement took place in1919. 五四运动发生在1919年。
How did the accident happened？这次事故是怎样发生的？
