【知识点解析】
1. 定语从句关系词的选择:在定语从句中,当先行词是物且在从句中作主语或宾语时,可选用which或that。例如题干中的第1题,先行词为"object",在从句中作主语,因此使用"that"。
2. as引导非限制性定语从句,可以指代整个主句,意为"正如"。如第3题,"Tom is addicted to the computer games, as his parents are worried about." 表示"正如他父母所担心的,汤姆沉迷于电脑游戏。"
3. which引导非限制性定语从句,指代前面整个句子或句中的某一部分。例如第10题,"There will be a twenty-minute break during the performance, when people can go to the restroom or buy some snacks." 其中"which"指代"休息时间"。
4. whose在定语从句中作为关系代词,表示所属关系。如第4题,"Ancient Rome was a country whose culture influenced the western world for centuries." 其中"whose culture"指的是"罗马的文化"。
5. 地点状语从句与关系副词:where引导的定语从句用于修饰表示地点的先行词,在从句中作地点状语。例如第9题,"Last Sunday I climbed to the top of the hill near my home, where I could see half of the city." "where"在此表示"在山顶上"。
6. 关系代词which在非限制性定语从句中,可以指代整个主句或句中的某个名词,如第12题,"We have gathered nearly 100,000 quilts, of which up to half have gone to the flood-hit areas." 其中"of which"指代"quilts"。
7. "such...as..."结构常用来引导定语从句,其中"such"为代词,"as"为关系代词,"such...as..."表示"像...那样的..."。如第7题,"The restaurant provides such cheap food as all the college students can afford." 这里"such cheap food"指代"食物","as"引导定语从句,修饰"food"。
8. "of which"引导的非限制性定语从句,表示所属关系,"of"表示从属关系。例如第14题,"Raising children is said to be a job for which parents receive the least formal training." "for which"在这里表示"对于这项工作"。
9. "the causes of which"结构在定语从句中,"which"指代前面的"causes"。如第13题,"A huge amount of oil was spilt on the East Sea, the causes of which are still under investigation." 这里的"which"指的是"油泄漏的原因"。
这些题目主要考察了定语从句中关系词的正确使用,包括which、that、as、where、whose等,以及它们在不同语境下的功能和意义。掌握这些知识点对提高英语阅读理解能力和写作能力至关重要,尤其对于准备高考的学生来说,是必不可少的训练内容。通过此类练习,考生可以更好地理解和运用各种定语从句,提升语言表达的准确性和丰富性。
