1.Most adults who are learning a second language would disagree with this statement.
①本句主语为：Most adults who are learning a second language;谓语为：would disagree with；宾语为：this statement
②主语中包含有一个语法点，定语从句。这是英语中一个非常重要的语法点.顾名思义，定语从句应该在整个句中做定语，请对比如下两句: He bought an interesting book.(定语) / He bought a book which is interesting.（定语从句）。具体介绍该语法点：
通常引导定语从句的关系代词有：who, whom, (一般指人), which(一般指物)，whose, that(人、物均可).关系副词有：when(时间), where(地点), why(原因)。不管是关系代词还是副词引导定语从句时，要在定语从句中充?#26412;?#23376;成分。上句中的who are learning a second language修饰先行词most adults, who 是关系代词，在从句中作主语。下面我们一起来看另几个例句：仔细听我的分析！
a.The man who/that will give us a talk has come.
b.I know a lady whose husband is a Nobel prize winner.
c.She’s the girl who/whom/that I met at the party.
d.I live in the room whose window faces south.
e.Did you find the bike that/which you lost?
④需掌握的短语：disagree with sb about / on sth
e.g. He disagrees with his wife about the education of their son.
2.They need hundreds of hours of study and practice…
hundreds of:几百，当hundred, thousand, million用作不确定数目时，需用?#35789;?#24418;式，并加介词of;当它们用作确定的数目时，不用?#35789;?#24418;式。
