不定式的时态有三种：
(1)不定式的一般式：to do。表示与谓语动词同一时间发生或动作发生在谓语动词之后。
(2)不定式的进行式：to be doing。表示与谓语动词同一时间发生，并且动作正在进行。
(3)不定式的完成式：to have done。表示发生在谓语动词之前。

11．To our surprise，the painting considered________should have won the prize.
A．being copied B．having been copied
C． to have copied D．to have been copied
解析：选D。considered是过去分词作定语修饰the painting。consider后面要求接不定式作宾(主)补，故可排除A和B。the painting和copy之间存在被动的关系，且copy动作发生在consider之前，故答案为D。此句意为“令我们吃惊的是，那幅被认为是抄袭的绘画作品竟获了奖。”
12.AIDS is said________the biggest health challenge to both men and women in that area over the past few years.
A．that it is B．to be
C．that it has been D．to have been

2【教材原句】 They say that the low-temperature lake is unlikely to be able to support such large living creatures.(P52)
他们说，水温这样低的湖泊不可能生存有体形如此巨大的动物。
【句法分析】 (1)本句可以转化为：They say that it is unlikely that the low-temperature lake is able to support such large living creatures.
(2) 本句使用了be unlikely to do sth.这一结构，它的用法等同于be likely to do sth.。主要有下述用法：
主语(具体人/物)＋be (un)likely to do sth.
?It(形式主语)＋be (un)likely to do sth.
It(形式主语)＋be (un)likely＋that-clause
【注意】 likely与unlikely不能用于It’s likely/unlikely for sb.to do sth.，而possible与probable是可以用于It’s possible/probable/impossible for sb.to do sth.。另外，(be)possible与(be)probable的主语不能是具体的某人或某物。
