答案详解

1.[C]【解析】名词近义词辨析。ingredients意为“（混合物中之）成分”，其他三个名词的意思是：elements“元素，要素”；components“（构成整体的）部件”；constituents“要素”。所以答案为C项。句意：做蛋糕的最主要的成分是面粉和糖。

2.[C]【解析】形近词词义辨析。这是四个都含有前缀trans-的名词的辨析。translation“翻译”；transition“转换”；transmission“传播”；transaction“交易”。因此只有C项符合题意要求。句意：文化传播表明人类把他们的语言从上一代传给下一代。

3.[B]【解析】名词词义辨析。illusion意为“幻想”，其他三个名词的意思是：justification“理由，辩护”；manifestation“展示，证明”；specification“评述，规范”。句意：我们必须摈弃幻想和假设来看问题，设法搞清丢失了什么。

4.[A]【解析】虚拟语气。would rather后接虚拟语气的从句，用一般过去时。句意：我宁愿你乘火车去，因为天气预报说明天有大雪。

5.[A]【解析】定语从句。关系副词when引导的定语从句修饰名词词组the rise of Nazism。句意：爱因斯坦于1921年获诺贝尔奖，在德国享有盛誉。后来随着纳粹主义的兴起，他被逐出德国，因为他是个犹太人。
