tom seldom pays his bills on time，and his brother does too 这句话错在哪

呵呵，这跟过去时没关系，本来就是一般现在时。

Tom seldom pays his bill on time， 这一句其实是否定句 = Tom doesn't normally pay his bill on time.
理解了这一句，后一个并列句的问题就很明显了。
问题一：too，一般是附和肯定，而前一句是否定句，所以不适合用在这里。
问题二：假定第一句真是肯定句，则要附和或避免重复的话，第二句的句式应为倒装句，如so does his brother.
问题三：因为这是否定句附和或避免重复，保持倒装不假，还应该是neither打头，正确的后一句应该为neither does his brother.

付完钱应该是过去式，用paid 再看看别人怎么说的。
