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：
