十、动词不定式的被动式和其他形式
The new hospital ______ is near the factory.
A. build B. builds C. to build D. to be built (青海省)
Key： D
[简析]当不定式的逻辑主语是不定式所表示的动作的承受者(宾语)时，用动词不定式的被动式，即：to be +过去分词;如果不定式所表示的动作发生在谓语动词表示的动作之前，不定式用完成式，即：to have +过去分词;
如果不定式表示的动作和谓语动词表示的动作同时发生，用不定式的进行式，即：to be +现在分词
比较and和or
1) 并列结构中，or通常用于否定句，and用于肯定句。
2) 但有时and 也可用于否定句。cloth 指布，为不可数名词 clothing 服装的总称
指一件衣服用 a piece of, an article of
2. incident , accident
incident 指小事件, accident 指不幸的事故 He was killed in the accident.
3. amount, number 请注意其不同特点：
There is no air or water in the moon。
There is no air and no water on the moon。
在否定中并列结构用or 连接，但含有两个否定词的句子实际被看作是肯定结构，因此要用and。 典型例题
---I don't like chicken ___ fish. ---I don't like chicken, ___ I like fish very much。
A. and； and B. and； but C. or； but D. or；and 答案C。否定句中表并列用or, but 表转折。
判断改错：
(错) We will die without air and water。
(错) We can't live without air or water。
(对) We will die without air or water。
(对) We can't live without air and water。
