I foten spend as much time as I can _____for my test

a.studying b.to study c.study d.have studied

这道题应该选哪个答案啊?为什么?请高人帮我详细讲一讲,谢谢

b as much time as i can 可以当成time，不影响句子成分

也就是 i often spend time to study for my test

选A：应用词组spend...(in) doing sth，as much time as I can是描述时间的短语。

spend to do sth 故B

应该选择答案a.
本句考查的知识点为spend sometime doing sth.“我经常花尽可能多的时间来为我的测验学习”。as much time as I can 整体作为spend的宾语
