e.g.
1.the paper cut into pieces;
2.the sunshine coming from the sun;
3.He stands there, listening to the music.

1．Some 20,000 tons of antibiotics are used in the European Union and the US each 2。year. More than half （指代antibiotics）are given to farm-animals to prevent 3。disease and promote growth. ___2___.
D：思路：空格前面句子中重复出现的词antibiotics，暗示空格处应该出现也涉及到antibiotics的内容，这样B，C，D都可能是答案。再从句子之间的逻辑衔接上看D合适：用观点性的转折自然结尾，而且D中的these farmyard drugs在空格前句中有呼应的内容half （指代antibiotics）are given to farm-animals。
考点：考察指示代词的呼应和特殊语意句子（转折句）。
