这里的 steal 为什么是原型
为什么  thieves 前面没有the
原文在Someone 后面有 had 请问，Someone told the police that thieves would try to steal the diamonds.与 Someone had told the police that thieves would try to steal the diamonds.意思都一样吗。这两种说法在语法上是否都正确。

steal前面是to,所以用原型,即try to do something
thieves前面不加the是因为不是特指哪些thieves
两个句子语法上都正确,但意思不一样,told那句是陈述一个事实,有人告诉了警察,后面had told一句是强调有人曾经告诉过警察.

第一个问题是因为前面是try to, to后面跟动词原型
后面一个问题， 我想不加the是因为不是特指的贼吧， 这个应该是有上下文的， 承在上文之下的，

try to do sth 动词不定式 后加动词原形 所以用steal
thieves 泛指
只有特指的时候用the
这个得看前后文的情景，时态没问题
had+ved过去完成时

因为try to 后加动词原形 不定式中 所有的v+ to 都跟动词原形 eg. want to, decide to, etc.如果加了the的话就说明thieves 的身份已被得知，就是指那几个小偷会去……而这里是指有小偷会去……
