英语纠错句子：Tim said he has finished the work last month.He said he will buy the computer.
我只是个初二的学生,求为什么
1.Tim said he has finished the work last month.
2.He said he will buy the computer.

答

Tim said he had finished the work last month.
He said he would buy the computer.
知识点如下：
1.在宾语从句中主句和从句之间的时态的一致关系,通常由主句谓语的时态决定从句谓语的时态.
A.若主句谓语动词是现在时或将来时,如：一般现在时,现在完成时,一般将来时,将来完成时等,从句可以根据需要使用任何时态.
B.若主句谓语动词是过去时态(一般过去时,过去进行时,过去完成时,过去将来时,过去将来完成时),从句谓语动词也必须是过去时态.
a.如果从句动作与主句动作同时发生,从句用一般过去时或过去进行时.
b.当从句动作发生在主句动作之前,从句要用过去完成时.
c.当从句动作发生在主句动作之后,从句要用过去将来时.
C.当从句表示客观事物或真理,或人们已经公认的道理时,其时态不受主句谓语动词的时态的影响.即使主句谓语动词使用了过去时的某种时态,从句的时态仍然是现在的某种时态.
D.当从句表示并未出现或尚未实现的愿望时,必须用过去时态.
E.有些形容词后面可跟有从句,这种从句一般可看作宾语从句,其谓语也应与主句谓语的时态保持一致.可跟这种宾语从句的形容词有：
afraid, glad, sure, confident, sorry,certain, conscious, aware等.一致的原则与宾语从句相同.
例如：I’m confident that I’ll pass the exam.我有信心通过考试.
He was lucky that he wasn’t killed.他很幸运没有被杀死.
