二、学海导航
【学法指要】
单元难点疑点思路明晰
1. So far as I know , it’s free . 就我所知,那是免费的
〖明晰〗so far as = as far as 引导比较状语从句,在句中作插入语,常用逗号与主句隔开。
So far as I know , not all of them passed the quiz .
2.The + 比较级 ,the + 比较级
First , it must be very light , the lighter the better . 首先,它必须很轻,越轻越好。
〖明晰〗the lighter the better 省略了不少的成分,补充完整是:the lighter it is , the better it will be . 这种句型表示前者与后者在程度上同样增加或者同样减少,汉语是“越……,越……”,前面是从句,后面是主句。又如:
The more we get together , the happier we will be .
The more , the better . 多多益善。
另外注意本单元出现的“比较级 + and + 比较级”表示“越来越……”。如:
Satellites are used more and more to take photos of the earth and to produce maps .
3.First , …… Second , ……
First , it must be very light , …… Second , it usually contains very expensive cameras .
〖明晰〗叙述事物的先后顺序时常用:First…, second …, third …, lastly …。也可以用:First…, secondly…, thirdly …, lastly … 。另外,高一曾学习过“first … later / then …” 以及“For one thing … ; for another …”句型表达顺序。如:
First , I wish you good health ; second , I wish you success in your work ; and third , I wish you good luck in everything .
4. Once + 时间状语从句
Once the satellite goes into its orbit round the earth , the panels are unfolded in order to catch the sunshine . 一旦卫星进入地球轨道,帆板就打开来吸收阳光。
〖明晰〗由 once 引导的时间状语从句表示“刚……就……”,“一旦……就……”。用以说明主句动作紧跟在从句动作之后发生。从句中用现在时代表将来时。从句还可以使用省略结构。如:
Once you step into our village , you’ll see how greatly it has changed .
Once seen , the film will never be forgotten .
5. 介词 + 关系代词型定语从句
There is a rocket motor on the satellite by which the direction of the satellite can be changed if necessary . 卫星上有一个火箭马达,必要时可以用它来改变卫星的方向。
〖明晰〗定语从句的先行词是 a rocket motor , by which 引导一个定语从句。定语从句中介词的选择受上下文的制约,或者与前面的先行词有搭配关系,或者与后面的动词有搭配关系。这里的 by 表“通过、用”。又如:
There are many research stations on the earth in which outer space is studied . (in 与 先行词 research stations 的搭配)
Who is the comrade with whom you just shook hands ?(with 与动词词组shake hands 的搭配)
另外,在定语从句中还有一个省略式的状语的 if necessary ,if 后省略了 it is 。又如:Put in an article where necessary . 在有必要的地方填上一个冠词。
【妙文赏析】
How easy it all was for police and emergency (紧急) service . A si
