ShanghaiisthebiggestcityinChina.=ShanghaiisbiggerthananyothercityinChina.=Shanghaiisbiggerthan(all)theothercitiesinChina.

上海包含在中国之内。作比较时，自己不能与自己作比较，应该把上海本身除外。Anyothercity是指除上海以外的任何一个城市。Theothercities是指把除上海以外的其他城市作为一方比较，都是合理的。记住anyother用名词单数,(all)theother后用名词复数。Heisthetalleststudentinourclass.anyotherstudentinourclass.(all)theotherstudentsinourclass.同义句：

比较级+thananyother+单数名词

=比较级+than（all）theother+复数名词

inJapan.上海不属于日本，可以和日本的任何城市比较，所以不要加other,记住无论是any,还是anyother都用名词单数。
