帮我看看这句话有没有语法错误，顺便翻译一下。

有语法错误哦。
（1）第一句This clock which can be heard on the B. B. C. 中是有which 来引导定语从句，所以这个只是短语（短语中有定语从句）。
（2） when it is striking 引导时间状语从句。
（3）because microphones are connected to the clock tower 引导原因状语从句
（4）把这三个练成一句话就是
This clock【 which can be heard on the B.B.C. 】is striking because microphones 【connected to the clock tower】 has rarely gone wrong.
（5）【 which can be heard on the B.B.C. 】是定语从句；【connected to the clock tower】是过去分词短语做后置定语。
（6）句子意思就是：这个在BBC（英国广播总台）能听到钟声的钟罢工了，因为接在钟楼上的麦克风坏了

应改为：This clock which can be heard on the B.B.C. is striking because microphones connected to the clock tower has rarely gone wrong.意思是：这个在BBC（英国广播总台）能听到钟声的钟罢工了，因为接在钟楼上的麦克风坏了。

这是一句话吗？好像是新概念课本上的新二 lesson71-A famous clock
On the B.B.C, you can hear the clock when it is actually striking because microphones are connected to the clock tower.Big Ben has rarely gone wrong.

你是把他们合成一句了吧。我觉得你最好把它写成两句话
Because microphones are connected to the clock tower， this clock can be heard on the B. B. C. when the clock is striking, it has rarely gone wrong
那个可以从BBC上听到的大钟，因为.钟塔上接了麦克风，所以种很少出差错。

有语法错误。。。
