二、学海导航
【学法指要】
单元句型思路明晰
1. Even when + 从句
Even when you are asleep , you are using energy . 甚至在你睡觉时，你也在消耗能量。
〖明晰〗even 作为副词放在由when引起的时间状语从句的前面起加强语气的作用。
Even when it is in August , the weather there is very cold .
Even when he was taking a holiday he was worried about his work .
2 . 主语 + be considered + to be + 主语补足语
The Chinese diet is considered to be the healthiest in the world . 中国饮食被认为是世界上最健康的饮食。
〖明晰〗consider 做“认为”时可以带不定式的复合结构，即：主语 + consider + 宾语 + 不定式（主要是 to be 做宾语补足语）。如果将宾语变为主语，则 consider 用被动语态，原来作宾补的不定式便变成为主语补足语。注意：to be 常常被省略后成为：consider + 宾语 + 名词（或者形容词）。
He considered the task to be the most difficult one . → The task was considered to be the most difficult one by him .
We all consider his suggestion to be reasonable . → His suggestion is considered to be reasonable .
We consider this (to be) a useful book . → We consider this book useful .
单元难点疑点释疑
1 . When playing football or basketball , you might be using 400 calories an hour . 踢足球或者打篮球时，你每小时可能要消耗 400 卡能量。
〖释疑〗连词 when , while 引起的时间状语从句，如果从句中的主语与主句中的主语是同一人或物时，则可以省略主谓语，变成“When / while + ing”这中结构。
While he was doing the experiment , he noticed something strange . = While doing the experiment , he noticed something strange .
2 . In some parts of Britain , one person in ten , by the age of thirty , has no teeth left . 在英国有些地方，十分之一的人年方三十，牙齿就掉光了。
〖释疑〗 one person in ten 即 one person in ten persons 的省略，其意思为“十个中有一个人”。与 one person in ten 类似的结构有：one person out of ten , one out of ten persons 。但是，ten to one 是“十有八九，很可能”。
Two teachers in ten are against this plan .
Three out of four people (= Three fourths of the people ) went there to have a look .
It will rain tonight ten to one .
另外，left 为过去分词作定语修饰 teeth ，其意思是“剩余的”。
There is but one chance left . 只剩下一个机会。
3 . scores of people went there in the first few days after its opening . 开张的头几天，许许多多人到那家餐馆去就餐。
〖释疑〗after 为介词，其后的物主代词所有格 its 及名词 opening (开张，开幕；开放)构成介词短语作状语。in the first few days “在头几天里”，这里，the first 不是“第一”，当其后接复数名词时，意思是“头几个，第一批”。
I was one of the first people to visit the newly built factory .
【妙文赏析】
One day , in Philadelphia , three men walked into the （1）Street Station . One of them went to the Information Center to check the departure-arrival listings (一览表) . There he （2） out that the three （3）train to New York was going to leave an hour later that day .
