试题分析：考查非限制性定语从句：句意：众所周知，技能是可以通过努力工作获得的。分析句子成分，两句话没有连词，说明前面的句子是非限制性定语从句，所填的词是关系代词，指代后面的句子，翻译成“正如”，用as引导非限制性定语从句。选B。
点评：非限定性定语从句起补充说明作用，缺少也不会影响全句的理解，在非限定性定语从句的前面往往有逗号隔开，如若将非限定性定语从句放在句子中间，起前后都需要用逗号隔开。需要注意 which，as都可以引导非限定性定语从句是用来说明前面整个句子的情况或主句的某一部分。但which引导非限定性定语从句只能放在后面，意思是“这…，那…”,as引导非限定性定语从句可以放在句首，句中，和句末。意思是“正如”。 |
