二、学海导航
【 学法指要 】
单元句型思路明晰
1 . 表语从句的句型
That\'s what we did in China in the old days .那就是我们中国从前的作法。
［明晰］What we did China in the old days 是表语从句。表语从句在句中作表语，它位于主句的连系动词之后。又如：
That\'s why she is so happy .
This is what we want .
The question is whether can finish our work by tomorrow evening .
2 . make + 宾语 + 动词原形
It makes me feel thirsty . 它使我感到口渴。
［明晰］①make 在此句中是“使，迫使”之意。make sb . do sth . 是一种跟不带 to 的不定式的结构，feel thirsty 就是不带 to 的不定式，作句中宾语 me 的宾语补足语。
He made them fear him . 他使他们惧怕他。
②在被动语态中，make 后面的不定式带 to . 如：
He was made to do it . 别人使他做的。
在主动语态的句子中，在 feel , hear , see , listen to , notice , watch , make , have , let 等动词之后的宾补，不定式通常不带 to。但是在被动语态的句子中，这些动词后不定式要带 to。例如：
主动语态：We heard him sing in the next room .
被动语态：Hw was heard to sing in the next room .
单元难点疑点释疑
1 . What was it used for ? 它用来干什么的 ?
［释疑］这是一般过去时的被动语态，助动词 be 根据人称的变化，变为 was 或 were。
I was called Xiao Mao at that time . 那时人们叫我小毛。
They were sent here by Uncle Wang yesterday .
他们是王大叔昨天送到这里来的。
2 . Can you tell me the way to the museum , please ? 请问你能告诉我去博物馆的路吗 ?
［释疑］下面问路的方式很常见：
Where is the museum , please ? 请问博物馆在哪里 ?
How can I get to the museum ? 我怎么去博物馆呢 ?
Which is the way to the museum ? 哪条路是通向博物馆的 ?
3 . Turn right at the second crossing . 在第二个十字路口处向右拐。
［释疑］这句话也可说成 Take the second turning on the right .
4 . Go across the bridge . 穿过那座桥。
［释疑］ ( 1 ) across 为介词，“横过，穿过”。cross 为动词，“横过，穿过”。crossing 为名词，“十字路口；人行横道；交叉点”。例如：
He can swim across the river . 他能游过河去。
He swims very well . He can cross the river . 他游泳游得很好，他能游过河。
Our school is on the corner of the crossing . 我们学校在十字路口的拐角处。
( 2 ) 辨异：介词 across 强调的是“横穿”，而介词 through 则强调“从……中间穿过”。例如：
Go through the back door , and you\'ll find a beautiful garden there . 穿过后门，你就会看到那里有一个漂亮的花园。
5 . You can\'t miss it . 你不会看到它的。
［释疑］ ( 1 ) miss 为动词时意为：fail to hit , catch , find , meet , hear , see , etc . 即：没打着，没赶上，没发现，没遇见，没听见，没看见等。例如：
He missed the ball . 他没接着球。
Did you miss the early bus ? 你没赶上早班车吗 ?
I\'m sorry I missed you at the station . 很抱歉，我在车站没见到你。
He never missed a day\'s work . 他从来没停过一天工作。
( 2 ) miss 在口语中，还常常用作“惦记，想念”。例如：
We all miss you very much . 我们都想念你。
You don\'t know how I miss you . 你可不知道我是多么惦记你。
( 3 ) 表示没做成什么事情时，要用 miss doi
