       If you are in a town in western country, you'll often see people walking with their dogs. It is still true that a

dog is the most useful animal in the world, but the reason why one keeps a dog has changed. Once upon a time, a man met a dog and wanted it to help him in the fight against other animals, and he found that the dog listened

to him and did what he told to. Later people used dogs for the hunting of other animals, and the dogs did not eat what they got until their master agreed. So dogs were used for driving sheep and guarding chickens.

       But now the people in the towns and cities do not need dogs to fight against other animals. Of course they

keep them to frighten thieves, but the most important reason is that people feel lonely in the city. For a child, a

dog is his best friend when he has no friends to play with. For a young wife, a dog is her child when she doesn't

have her own. For old people, a dog is also a child when their real children have grown up and left. Now people

do not have to use a dog, but they keep it as a friend, just like a member of the family.

问答题


甲公司委派业务员张某去乙公司采购大蒜,张某持盖章空白合同书以及采购大蒜授权委托书前往。
  甲、乙公司于2010年3月1日签订大蒜买卖合同,约定由乙公司代办托运,货交承运人丙公司后即视为完成交付。大蒜总价款为100万元,货交丙公司后甲公司付50万元货款,货到甲公司后再付清余款50万元。双方还约定,甲公司向乙公司交付的50万元货款中包含定金20万元,如任何一方违约,需向守约方赔付违约金30万元。
  张某发现乙公司尚有部分绿豆要出售,认为时值绿豆销售旺季,遂于2010年3月1日擅自决定与乙公司再签订一份绿豆买卖合同,总价款为100万元,仍由乙公司代办托运,货交丙公司后即视为完成交付。其他条款与大蒜买卖合同的约定相同。
  2010年4月1日,乙公司按照约定将大蒜和绿豆交给丙公司,甲公司将50万元大蒜货款和50万元绿豆货款汇付给乙公司。按照托运合同,丙公司应在十天内将大蒜和绿豆运至甲公司。
  2010年4月5日,甲、丁公司签订以120万元价格转卖大蒜的合同。4月7日因大蒜价格大涨,甲公司又以150万元价格将大蒜卖给戊公司,并指示丙公司将大蒜运交戊公司。4月8日,丙公司运送大蒜过程中,因山洪暴发大蒜全部毁损。戊公司因未收到货物拒不付款,甲公司因未收到戊公司货款拒绝支付乙公司大蒜尾款50万元。
  后绿豆行情暴涨,丙公司以自己名义按130万元价格将绿豆转卖给不知情的己公司,并迅即交付,但尚未收取货款。甲公司得知后,拒绝追认丙公司行为,要求己公司返还绿豆。
  

甲公司能否以未收到戊公司的大蒜货款为由,拒绝向乙公司支付尾款?为什么?
