十六、形容词最高级省略结构 The crane is the tallest bird of the wading birds. 最高级后面的名词与范围名词重复,可以省略,句子变为The crane is the tallest of the wading birds.

例1:The crane is___of the wading birds.    (A) the tallest    (B) the tallest that is    (C) which is the tallest    (D) which the tallest is 分析:空格前是主语和谓语,空格后是of引导的介词短语,空格处明显缺作表语的名词或名词短语。四个选项中只有(A)使句子结构完整,语义清楚,故选(A)。

例2:. Cows are said to be the least intelligently of        A  B       C    domestic animals.     D 分析:改为形容词,intelligent,intelligently为副词,不能作表语。

十七、规则动词过去分词作定语结构这里的规则动词指的是过去式和过去分词一样,导致考生看不出句子结构,比如:  program, programmed, programmed 因此判断这个词是过去式还是过去分词就显得比较重要:  第一步:从逻辑上判断这个动作是主动还是被动  第二步:如果是被动的话,做谓语前面一定有系动词be

例1:___Wupatki National Monument in Arizona features structures built of red sandstone by ancestors of the Hopi people.    (A) That the    (B) In the    (C) Around the    (D) The 分析:空格后是结构完整的句子,空格处显然缺定冠词the 修饰主语,故选D。A中that引导主语从句,使整个句子变成从句而无主句,B、C构成介词短语,使句子缺主语,故排除。句子中的built是过去分词。

例2:Antibodies ___by small, round cells called lymphocytes and plasma cells.    (A) to be made    (B) making    (C) made    (D) are made 分析:空格前为名词作主语,空格后是介词by引导的动作执行者,called是过去分词作定语,所以句子缺谓语,故选D。A、B、C均为非谓语动词,故排除。

例3:Automatons programmed to perform a given task ___the flexibility and adaptability of human beings.    (A) without    (B) lack    (C) minus    (D) not having 分析:programmed在句中是过去分词作名词后置修饰语,空格处缺谓语动词。四个选择答案中只有(B)是可作谓语的动词,故选(B)。 B, programmed是一个定语,而不是谓语,机器人被编制程序,所以是过去分词,而不是谓语动词
