语法——被动语态。
（1）英语动词有两种语态.，主动语态和被动语态。主动语态表示主语是动作的执行者，被动语态表示主语是动作的承受者。如：
They will build a new bridge over the river. (主动) A new bridge will be built over the river. (被动)
汉语中常用“被”、“给”、“由”、“受”等词用来表示被动，而英语用： 助动词be + 及物动词的过去分词构成。 （2）主动语态变为被动语态要加“to”的情况。
若宾语补足语是不带to 的不定式，变为被动语态时，该不定式前要加\。此类动词为感官动词，如：feel, hear, help, listen to, look at, make, observe, see, notice, watch等。例如： The teacher made me go out of the classroom. I was made to go out of the classroom (by the teacher). （3）主动形式表示被动意义。
如 wash, clean, look, cut, sell, read, wear, feel, draw, write, sell等动词虽然用做主动形式却表示被动的意义。例如：The food tastes good.
(4) 被动语态的时态、人称和数的变化
主要体现在be的变化上，其形式与系动词be的变化形式完全一样。列表如下：
一般现在时：am / is / are + done 一般过去时：was / were + done 一般将来时：shall / will + be done 一般过去将来时：should / would + be done 现在进行时：am / is / are + being + done 过去进行时：was / were + being + done 现在完成时：have / has + been + done 过去完成时：had + been + done 练习：

Unit 3 Traditional skills
一、要点概括
二、hang on 用作电话用语（其后可接a minute, a moment, a while之类的词），意为：等一下；别放下电话；别挂断。
1. reach 除了“到达”外，还有“伸手去够或拿”的意思。如： Some oranges are hard to reach.
The girl was short so she couldn’t reach the cup on the table. 【区别】get, reach和arrive
? get是不及物动词，常和to连用。但当“到达”的地点是home或副词（here, there）时，to需要省略。如：When did you get there last night? I get home at 7:00 pm every day.
? arrive为不及物动词，后须加上介词in/ at才能连接表示地点的名词。
表示到达大城市或国家时要用arrive in，而到达乡村、车站等小地方则用arrive at。如：We arrived in London last week.
The doctor arrived at the village at last.
D. will finish
