历年托福考试语法真题全面解析14
26. Industrial buyers are responsible for supplying the goods and services that an organization required for its operations.答案：D
测试点：时态一致。
分析：以不划线的are做线索，看出本句的基本时态是现在时，讲述的是一般性的事实。故此处不应用过去时，required应为require.
27. The most easiest process for mining gold is panning, which involves using a circular dish with a small pocket at the bottom.
答案：A
测试点：最高级。
分析：遇到含有形容词最高级的题时，既要注意the和-est或most是否缺失，也要注意-est和most是否重复使用。此处most多余。
28. Farm animals have been regardless by nearly all societies as a valuable economic resource.
答案：B
测试点：词性/被动语态。
分析：看到系动词be和by同时出现，应注意二者之间划线的词是否过去分词。此处regardless(形容词)应为regarded.
29. Although it is any longer the big business that it was in the forties, radio continues to be a medium of essential communication, especially at the local level.
答案：A
测试点：习语／no和any的用法。
分析：no longer是固定说法，用在肯定句中。any longer则用在否定句和疑问句中。(A)前是肯定的it is，故此处用no longer。
30. The field of dynamics in physics is concerned with a particle’s motion in relation to the forces acting it.
答案：D
测试点：缺词。
分析：act为及物动词时意为“扮演(角色)”，而此处意为“起作”，应为不及物动词，不能直接加宾语。应为acting on／upon it。
