请问英语句子：I lost my watch last week 怎么改成宾语从句?

he tells me that he lost his watch last week.
He told me that he had lost his watch last week.
第一句主句是一般现在时,用tells,而从句是last week ,应用一般过去式
第二句主句是一般过去时,用told,从句是过去的过去,用过去完成时.
还是不太懂的话可以再问我O(∩_∩)O~那例如"We weren't ready"这种有be动词的呢？weren't 是过去式，如果用在第一句中做从句的话还是一般过去时，用weren't在第二句的从句中用过去完成时，weren't 改为had not been
