英语改错 Are there seats for us third?知道的帮下,记得说明理由哈

1.Are there seats for us three?这儿能坐下我们三个吗?
基数词可以用作同位语,如这句的three作us的同位语,而序数词没有这种用法.
2.They are going to build a 150-metre-high hotel and the tallest one in the city.
像150-metre-high这样包含连词符“-”的,通常要放在名词前作定语修饰该名词,类似的用法还有a 12-year-old boy 一个12岁的男孩.

are there seats for us three?有我们三个的座位吗？应该用基数词，而third是序数词。
they are going to build a hotel 150-metre-high which is the tallest one in the city.
变成了一个定语从句，限定一下宾馆这个名词的数量，如果没有which is就会让人误解为你要造两座宾...
