[误] I have nothing to do but to cry.??
[正] I have nothing to do but cry.??
[析] 在这一结构中but后面要用省to的不定式。??
number ??
[误] A number of news can be heard on TV today.??
[正] A lot of news can be heard on TV today.??
[析] a number of后接可数名词复数。??
[误] The number of students are ten thousand.??

[析] a number of 其意为"大量的",而the number of…是"某某的数量"。即the number of students意为"学生人数",所以要用单数形式的谓语动词。??
