重点句子
1. Wu Yifan and his fa ( http: / / www.21cnjy.com )mily are going on a trip to the countryside. 吴一凡和他的家人打算到乡村去旅游。2·1·c·n·j·y
【点拨】◆family可以 ( http: / / www.21cnjy.com )看作一个整体，指“家庭”；也可以指“家人”，翻译时应灵活把握。如：I have a big family. 我有个大家庭。www-2-1-cnjy-com
My family ar ( http: / / www.21cnjy.com )e going to get together and have a big dinner. 我全家打算聚在一起大吃一顿。【来源：21cnj*y.co*m】
◆go on a trip表示“旅行； ( http: / / www.21cnjy.com )旅游”，相当于take a trip。需要注意的是，含有动词go的短语，如 go for a walk, go swimming, go for a picnic，要用现在进行时来表示将要发生的动作。又如：
We are going for a walk this evening. 今晚我们打算去散步。
2. It is getting lo ( http: / / www.21cnjy.com )wer and lower, but his shadow is getting longer and longer. 它（太阳）渐渐西下，但是你的影子变得越来越长。www.21-cn-jy.com
【点拨】◆这是一个由转折连词but ( http: / / www.21cnjy.com ) 连接的并列句，连接前后两个简单句的连词还有and（表示并列关系）, or（表示选择关系），so（表示因果关系）等。如：
He studies very hard ( http: / / www.21cnjy.com ), and he wants to work in a university. 他学习很努力，并且他想在大学里工作。【来源：21·世纪·教育·网】
Be careful, or you will hurt yourself. 小心点，否则你会伤到自己。
Bill is ill at home, so he can’t come to the party. 比尔生病在家，所以他不能参加聚会。
◆“比较级+and+比较级”表示“越来越……”，与这类结构搭配的常用动词有grow, get, become等。21*cnjy*com
词语辨析
善“变”的 get, grow, become
get, grow, become都含有“变得”意思，但在使用上还有些区别。
▲get多用于口语，表示一种变化过程，强调的是“渐渐变得”，后面经常接形容词的比较级形式。如：
It’s getting darker and darker outside. 户外天色越来越暗。
In winter the days get shorter. 冬季白天变得较短。
▲become常用来指人的情绪或天气状况的变化，后面跟形容词，这时可以与get互换；有时become也强调变化过程的完成，后面跟名词。如：21cnjy.com
The old man often becomes angry these days. 这些日子这个老人经常生气。
You’re becoming a big beautiful bird. 你在变成一只又大又美丽的鸟。
▲grow 也表示“逐渐变得”，多用来指人或物的外部状态的变化。如：
The girl is growing thinner and thinner. 这个女孩越来越瘦了。21·cn·jy·com
My younger brother is growing tall．我的弟弟渐渐长高了。
