关于as...as前后一致问题

1. Mary has as many books as Jerry (has).

2. Mary's books are as many as Jerry's.

3. Mary gave us the same book as Tom did.

请教老师1，2，3话都正确吗？

如果把第2句改成Mary's books are as many as Jerry 是否正确？

如果把第3句改成Mary gave us the same book as Tom 是否正确？

请问什么情况下可以省略第二个as后面的动词？

1. Mary has as many books as Jerry (has). （正确）

2. Mary's books are as many as Jerry's.（错误：many一般不作表语，改为上句。）

3. Mary gave us the same book as Tom did.（语法正确，但语义模糊：两个人分别给了我们同一本书？）

请教老师1，2，3话都正确吗？

如果把第2句改成Mary's books are as many as Jerry 是否正确？

（错误：many 一般不作表语，此外，即便可以作表语，但比较的两者必须是同等的人或事物。books能和Jerry比较吗？）

如果把第3句改成Mary gave us the same book as Tom 是否正确？（前面分析过，语义模糊。）

请问什么情况下可以省略第二个as后面的动词？

（前提是不引起歧义。）

夸克《英语语法大全》关于比较分句省略/替代的举例：

James enjoys the theatre more than Susan enjoys the theatre.

James enjoys the theatre more than Susan enjoys it.

James enjoys the theatre more than Susan does.

James enjoys the theatre more than Susan.

James enjoys the theatre more.

省略有个前提：不能导致误解或语义不清。

只有二种情况可以省略从句从句主语而保留谓语。1 than占据了主语位置。2 从句的主语是形式主语it，连同that从句一起省略。详细情况可参考http://ask.yygrammar.com/q-25146.html
