大家来分析这个英语句子的主谓宾等其他成分
The fact that programs in these languages,although made up largely of English words and some well-known mathematical symbols,are unintelligible to the lay reader indicates the gulf which still exists between the kind of verbal instructions which can be given to another human,and the coded instructions required by the computer.

答案

主语：The fact
谓语：indicates
宾语：the gulf
the fact that后是同位语从句,解释fact的具体内容,该从句到to the lay reader结束
gulf后的which引导定语从句,到the computer结束；其中又套了一个定语从句：which can be given to another human,是instructions的定语从句.
