2. The birds in their pictures are really beautiful.
3. People make space for farms and buildings by making wetlands smaller.

【分析】
做这类遣词造句题，需先明确句子的时态、固定短语和结构：1. 第一句使用现在完成时，“学习”对应learn，“different kinds of”修饰名词复数birds，要放在正确位置；2. 第二句中副词really需修饰形容词beautiful，要放在be动词与形容词之间；3. 第三句中by是介词，后接动名词，“腾地方”是固定短语make space for，“make wetlands smaller”是“使湿地变小”的正确表达。
【解析】
1. 现在完成时结构为have/has+过去分词，“学习”用learn的过去分词learned，“different kinds of”修饰birds，故句子为I have learned much about different kinds of birds.
2. 主系表结构中，副词really修饰形容词beautiful，“在他们的画中”译为in their pictures，故句子为The birds in their pictures are really beautiful.
3. 介词by后接动名词表方式，“腾地方”是make space for，“使湿地变得更小”是make wetlands smaller，故句子为People make space for farms and buildings by making wetlands smaller.
【答案】
1. I have learned much about different kinds of birds.
2. The birds in their pictures are really beautiful.
3. People make space for farms and buildings by making wetlands smaller.
