201、The quality of teaching should be measured by the degree ________ the students' potentiality is developed.（财科所2015年）

1. of which
2. with which
3. in which
4. to which

答案：D

解析：定语从句，固定搭配考点。题干关键词“degree”后的定语从句是修饰成分，指达到何种程度，以何种程度为衡量标准，再由to the degree是固定搭配知此题答案选项为D。

202、Another food crop raised by Indians ________ strange to the European was called Indian corn.（财科所2015年）

1. who were
2. that were
3. that was
4. who was

答案：C

解析：定语从句考点。“raised by Indians”相当于“which was raised by Indians”，是第一个定语从句，修饰“Another food crop”；主语是一个抽象的不可数名词，根据题目后半部分的意思可知，横线所选词与“strange to the European”构成第二个修饰主语的定语从句，并且充当“was called Indian corn” 的主语，因此选择that指代“Another food crop”，故本题答案选项为C。

203、We moved to the new house in the suburbs so that the kids would have a garden_______.（财科所2015年）

1. in which to play
2. to play with
3. to play
4. where to play

答案：A

解析：定语从句考点。play in a garden是固定用法，表示“在花园里玩耍”，因此用一个which引导的定语从句修饰garden。D选项是where引导的地点状语从句，与garden重复。故本题答案选项为A。

204、There are many copper mines in the state of Arizona, ______ contributes significantly to the state's economy.（财科所2015年）

1. a fact
2. which fact
3. whose fact
4. That

答案：C

解析：非限制性定语从句考点。根据题目的意思，亚利桑那州有很多铜矿，“铜矿多”这一现状对于该州的经济发展贡献重大。若认为后半句话是同位语从句，则应该是“a fact that/which...”，故A选项错误；“which” 引导非限制性定语从句，后面不需要接名词，故B选项错误；“that”不可引导非限制性定语从句，故D选项错误；由此知本题答案选项为C。

205、Hydrogen is the fundamental element of the universe _______ it provides the building blocks from which the other elements are produced.（财科所2015年）

1. so that
2. but that
3. in that
4. provided that

答案：C

解析：状语从句考点。根据题目结构，填空处前后均为简单句，因此需要一个连词来连接。so that“因此”，引导目的状语从句，不符合题意；but that“要不是；若非”，引导条件状语从句，不符合题意；provided that“以…为条件，条件是…”，引导条件状语从句，不符合题意；in that“原因是”，相当于because，引导原因状语从句，根据句意，主句是结果，因此从句应该说明原因，故本题答案选项为C。
