he has to deduce what he can中what做什么成分？

引导宾语从句

1.he has to deduce what he can from the few scanty clues available。 what 引导的宾语从句中，我知道省略了动词 deduce 实际是what he can deduce 主干是 he has to decuce (what he can ) from (the few scanty) clues... 2.when the writer went to the station master ,he complained about.... 这里的 go to sb意思是 去找某人？yes. 有这种用法吗？有 go to 有转向的意思 （turn to 的意思） go to a dictionary for a word 翻字典查一个词 3.when they come to record the history of our own times 还有come to exist 。 那come to do 还有开始 做某事的意思？ come to v. 达到, 继承, 复苏, 停止 想起,共计 4.ruin damage destory区别 主要讲ruin ，其他我明白. ruin v. (使)破产, (使)堕落, 毁灭 用ruin 很多时候有堕落的意思。。。damage 和destroy没有这种意思。。 ruin oneself 毁掉自己， 自甘堕落。。。 后面两个问题，你好好查查字典。。大相径庭了。。
