Habits are easy to make but hard to break . ( Habits是to make、to break的逻辑宾语 ) 。
The water is fit to drink .
The picture is pleasant to look at .
2 . 当不定式所修饰的名词或代词是动词的宾语，而句子的主语也是不定式的逻辑主语时。例如：
Mathilde only has a small cold room to live in . ( Mathilde是to live in的逻辑主语 )
He bought some magazines to read . ( He是to read的逻辑主语 )
3 . 当不定式所修饰的名词或代词，是及物动词的直接宾语，而间接宾语是不定式的逻辑主语时。例如：
Mother always gives her little daughter some picture books to read . ( Her little daughter是to read的逻辑主语 )
The teacher gave the students some paper to write on . ( The students是to write on的逻辑主语 )
4 . 当不定式所修饰的名词或代词，是“there be…. ”结构句中的主语时 ( 此处用主动或被动式，一般说来无意义上的不同 ) 。例如：
There are many problems to work out . ( to be worked out )
(二) 在动词want、need、require等后面常用动名词表示被动含义，等于不定式的被动形式。再如：
The bike needs ( wants ) repairing ( = to be repaired ) . 自行车需要修理了。
(三) worth后跟动名词主动形式表示被动，但是不跟不定式的被动。再如：
This novel is well worth reading。这本小说很值得阅读。
(四) 有些动词不及物动词，只有主动形式，常视为主动表被动。如：
1 . take place、happen、break out等。
A big fire happened / took place / broke out last night .
2 . 感官动词 ( taste ; feel ; smell ; sound ; look ) 用主动形式表示被意思。请看：
How sweet the music sounds !
Good medicine tastes bitter to the mouth .
3 . write、read、sell、keep、prove、weigh、number、drink、wear、pay、wash、open常用主动形式表被动意义。请看下面句子：
The book sells well . ( 这本书销路很好。 )
The door will not open . ( 这扇门就是打不开。 )
This dress washes better . ( 这衣服较好洗。 )
The sign reads as follows . ( 这牌子告示如下。 )
三、be made of及其他
1 . 制成品中能看出原料，用be made of ; 制成品的原料变化看不出来，用be made from。如：
The desk is made of wood .
Paper is made from wood .
2 . 用of时可用out of表示语气的加强。如：
This cup is made out of glass .
We make bread out of flour . (不要省去out。成品(bread)做宾语时，要说out of。)
3 . 原料前用with , 表示这种原料是这种制成品的主要原料，或能说明其特点的一种原料，或者强调用什么材料。如：
A fruit cake is made with fruit .
Can you make a boat with this piece of wood ?
4 . make…into…意为“将(什么原料)制成(什么成品)”。如：
Glass can be made into cups .
We can make glass into cups .
5 . be made up of，意为“由……组成，由……构成”，相当于consist of。如：
Our class is made up of sixty students .
This machine is made up of hundreds of different parts .
6 . be made in+地点，意为“由(某地)制造，在(某地)制造”。如：
This machine is made in China .
