改错:（1）The highway was closed because the heavy snow that had nevew been seen for fifty years.
（2）The large number of people in China are learning English now.
每个句子一个错误.
为什么？
答
because-because of
The-A
第一题：because后接从句,而because of后接名词或名词短语,原句 the heavy snow 是名词短语,后面that had nevew been seen for fifty years是定语从句,作the heavy snow 的定语,所以应用because of.
第二题：A large number of 是固定词组,
A large number of +可数名词复数,表示大量的
没有The large number of.
