A.whatB.whichC.thatD.it

答案B。which可代替句子，用于非限定性定语从句，而what不可。that不能用于非限定性定语从句，it不为连词，使用逗号连接的两个句子并在一起在英语语法上行不通。3）Itrainedhardyesterday,____preventedmefromgoingtothepark..
A.thatB.whichC.asD.it

答案B.as和which在引导非限制性定语从句时，这两个关系代词都指主句所表达的整个意思，且在定语从句中都可以作主语和宾语。但不同之处主要有两点：
（1）as引导的定语从句可置于句首，而which不可。
（2）as代表前面的整个主句并在从句中作主语时，从句中的谓语必须是系动词；若为行为动词，则从句中的关系代词只能用which.。在本题中，prevent由于是行为动词，所以正确选项应为B。关系代词as的用法what/whateverwho/whoever先行词和关系词二合一1.Cityp
