求英语大神帮忙看一下这句话里面存在的语法！！！过两天要讲给别人听的！！

最害怕的就是你这种情况，自己都搞不懂，又如何能讲给别人听呢？如果真要为人师，还是扎实点，会的教给别人，不会的直言自己也不很擅长，别误导学生。1. graduates shouldn't be deceived into thinking they can back off simply because things have become more difficult. Thinking 和后面的they can be back off simply 之间省略了that, “they can back off simply because things have become more difficult.” 整体是宾语从句，是thinking的宾语。 在这个宾语从句中又有副词引导的原因状语从句 because things have become more difficult. 即宾语从句中套有状语从句。2. A large number of people chasing relatively fewer opportunities can create strong competitive pressure. 这里是很典型的名词从句简化为动名词短语做主语。A large number of people chasing relatively fewer opportunities，实际上是 That a large number of people are chasing relatively fewer opportunities 的简写形式.
