OC上的语法题
27.In many large cities in the United States,the presence of a (A)culturally diverse population (B)has led to repeated calls (C)that curricula taught (D)wholly or partly in languages other than English.(E)No error
这题答案是把that改成for,为什么呢?能分析一下这个句子的各个语法成分吗?
28.(A)Of ancient origin,the game of checkers (B)was played in Egypt (C)during the time of the pharaohs and (D)is mentioned in the writings of Homer and Plato.(E)No error
这题答案是no error,可是我觉得D应该把is改成was啊,不应该是过去时吗?
PS：为毛总觉得OC的语法题怪怪的呢~

答案

1.that引导的是句子,call for 后面加名词,呼吁某物,根据句子,call后面跟的是名词curricula,因此用for
地点状语：In many large cities in the United States,
主语：the presence
主语补语：of a culturally diverse population 介词短语修饰主语
谓语：has led to
宾语：repeated calls for
介词for的宾语：curricula （taught wholly or partly in languages other than English过去分词修饰curricula）
翻译：在美国的许多大城市,由于文化差异较大的人群的出现,人们反复呼吁不再仅仅使用英语一种语言来进行课程的教学,而是应该完全或者部分使用多种语言来进行教学.
2.没有错误
因为后面的is是指著作中提到,指著作的内容通常用一般现在时
