1990年08月语法题 1. Resin is a substance that ---in water. (A) does not dissolve (B) do not dissolve (C) not dissolving (D) not dissolved 答案：A测试点：谓语． 分析：that从句有主语而缺谓语．应在答案中选择可作谓语的动词形式，即(A)．(B)动词的数与主语不一致；(C)、(D)是分词，不可作谓语． ? 2. ---hardiness, daylilies can be cultivated particularly easily. (A) Their (B) Since their (C) It is their (D) Because of their 答案：D测试点：介词短语。 分析：逗号后是一完整的句子，逗号前常常是状语，由分词短语或介词短语充当．答案中无分词，只有(B)(D)是介词结构．since作介词时不表示原因，而是“自从…”的意思．(D)是正确答案。Because of是介词短语。 ? 3.A biologist does not merely describe organisms, but tries to learn ---act as they do. (A) what cause them to (B) causes them to what (C) what to cause them (D) what does to them 答案：A测试点：宾语从句． 分析：1earn后的宾语从句主谓语均缺，应选择主语+动词+…的形式．(B)缺主语；(C)to cause不能作谓语动词；(D)what为单数意义，动词应当用第三人称单数形式．(A)正确． ? 4.Vaporization in connection with general --- has a marked effect on long – term climate. (A) atmospheric conditions that (B) conditions are atmospheric (C) are atmospheric conditions (D) atmospheric conditions 答案：D测试点：介词宾语． 分析：介词with要求名词性的成份作宾语，而4个答案中只有(D)是名词词组．(A)后接从句；(B)(C)均含有动词． ? 5. The oldest city in the state, --- . (A) the Hudsons Bay Company founded Vancouver, Washington, in the early nineteenth century (B) the founding of Vancouver, Washington, by the Hudsons Bay Company in the early nineteenth century (C) Vancouver, Washington, was founded by the Hudsons Bay Company in the early nineteenth century (D) In the early nineteenth century with the founding of Vancouver, Washington, by the Hudsons Bay Company 答案：C测试点；主语一致。 分析：逗号前是名词性短语，为同位语，逗号后应是完整的句子。句首的同位语说明的是句子的主语，故主语应与city同义．答案中(C)是完整的句子，且以城市名为主语．(A)虽是句子，但主语是company，与同位语不一致；(B)(C)不是句子． 解题要点：这类含有同位语的考题，通常有冗长复杂的4个答案．简捷的方法是快速浏览各答案的第一个单词，寻找与同位语相同含义的词语，如此句中的Vancouver(温哥华)即是city． ? 6. --- raw materials into useful products is called manufacturing. (A) Transform (B) Transforming (C) Being transformed (D) When transforming 答案：B测试点；主语／动名词。 分析：由单数系动词is可以推知materials不是主语，主语缺，而into又提示了此主语应具有动作性，故选(B)动名词transforming．动名词短语作主语要求其谓语为单数形式． ? 7.
