我低头朝水中看去，看到老汤姆正在船边游着，为我们引路。
swimming by the boat 在句中作宾语补足语，与宾语Old Tom 存在逻辑上的主谓头系。
I saw Jack crossing the street.
我看见杰克正在穿过街道。 7. A few minutes later, there was no Tom, so George started beating the water with his oar and there was Tom, circling back to the boat, leading us to the hunt again.

辨析：wound, injury, hurt,
wound 是战斗中刀枪的创伤、伤口
His brother was wounded in that battle .
injury 是平时的大小创伤和伤害
He got serious injuries to the legs at work .
hurt 是指精神上的伤害和肉体的伤痛。
The hurt to his feelings is more serious than the hurt in his body .
这是一个it作形式主语的句子，真正的主语是不定式to handle the boat。在以不定式、动名词从句作主语的句子里，通常以it作形式主语，而把真正的主语后置以避免头重脚轻。这样的句式通常有：10. … it was difficult to handle the boat. …… 划船很困难。 11. It took over half an hour to get the boat back to James.
用了半个多小时的时间才把船划回到詹姆斯身边。 这是一个It takes (sb.) some time/sth. to do sth. 的固定句式，take 意为“花费、需要”，take 前也可用具体名词作主语。

Unit 3 Under the Sea
Period 3 Grammar: Revision of Passive VoiceModule 7 Revision of the Passive Voice
1．被动语态的基本用法
被动语态由助动词be ＋ 过去分词 构成。 ⊙及物动词才有被动语态，不及物动词没有被动语态。
主动与被动的转换：
把主动句的宾语变成被动句的宾语然后把谓语动词变成be ＋ 谓语的过去分词
主动：Everyone likes delicious food.
被动：Delicious food is liked by everyone. 2．被动语态在各种时态中的应用，时态通过助动词be表现出来。3．被动的特殊情况：主动形式表被动含义
1）动词need, require, want等后面的宾语用动词ing表示被动意义，其含义相当于动词不定式的被动形式to be done. 即need doing = need to be done.
如，The car needs repairing. = The needs to be repaired.
2) 形容词worth + doing = worthy to be done, 注意，worth 后面不跟动词不定式。
如，The film is well worth seeing. = The film is very worthy to be seen.
3) 连系动词（Link-verbs）不用被动，如look, feel, taste, smell, remain, etc.
例如，Your dress looks beautiful.
The stone feels cold.
4) 形容词+ to do主动表被动：形容词nice，easy，fit，hard，difficult，important，impossible，pleasant，interesting等在句中做表语或宾补时，句子的主语/宾语又是不定式的逻辑宾语时。
如，This problem is difficult to solve. (solve this problem, 句子主语problem是不定式to solve的逻辑宾语，这时to solve主动表被动)
同样的情况，还会出现在too…to, enough to do的结构中
如，This mobile phone is too expensive (for me) to buy. (不定式前还可以加逻辑主语for me）
The room is not enough (for us) to live in.
5）break / wash / sell / read / translate 等动词也常用主动表示被动。
例如，The cup breaks easily. The novel sells well.
cost / take（花费）, last（持续）, have（有）这些动词表示括号内的意思时习惯上也不用被动。
例如，The sweater costs a lot. The rain lasted for three days.
4. 分清被动语态与系表结构：
被动语态中be+过去分词表示主语承受的动作；而系表结构（be+表语）表示主语的特点或所处的状态，be后面的过去分词是表语，相当于一个形容词。
例如，The window is broken．
（系表结构，说明window的状态/特点）
The window was broken by the naughty boy．
（被动语态，说明window是由the boy打烂的）练习
