my mother ( )work on a farm has to,have to,has,have填哪个
应该是
has to
我妈妈不得不在农场工作.
主语三单,一般现在时,所以必须用has
如果用完成时,后面动词work为过去分词才行,所以只能是has to

has to 。（ mother是第三人称单数。排除 have to 和have 。 has：表现在完成时。后应该是worked）

has to。
have/has to表示必须，不得不的意思，后接动词原形。
have/has 加动词过去分词，表示一直在做某事。
根据题干后面动词原形work，推断has/have错误，而my mother是第三人称单数，所以用has to.
