     We each have a memory. That's why we can still remember things after a long time. Some people

have very good memories and they can easily learn many things by heart, but some people can only

remember things when they say or do them again and again. Many of the great men of the world have

got surprising memories.

      A good memory is a great help in learning languages. Everybody learns his mother language when

he is a small child. He hears the sounds, remembers them and then he learns to speak. Some children are

living with their parents in foreign countries. They can learn two languages as easily as one because they

hear, remember and speak two languages every day. In school it is not so easy to learn a foreign language

because the pupils have so little time for it, and they are busy with other subjects, too.

     But your memory will become better and better when you do more and more exercises.

(三)

某大型给水工程项目由政府投资建设,业主委托某招标代理公司代理施工招标。招标代理公司确定该项目采用公开招标方式招标,招标公告在当地政府规定的招标信息网上发布。招标文件中规定:投标担保可采用投标保证金或投标保函方式担保。评标方法采用经评审的最低投标价法。投标有效期为60d。
业主对招标代理公司提出以下要求:为了避免潜在的投标人过多,项目招标公告只在本市日报上发布,且采用邀请招标方式招标。
项目施工招标信息发布以后,共有12家潜在的投标人报名参加投标。业主认为报名参加投标的人数太多,为减少评标工作量,要求招标代理公司仅对报告的潜在投标人的资质条件、业绩进行资格审查。
开标后发现:
(1)A投标人的投标报价为8000万元,为最低投标价,经评审后推荐其为中标候选人。
(2)B投标人在开标后又提交了一份补充说明,提出可以降价5%。
(3)C投标人提交的银行投标保函有效期为70d。
(4)D投标人投标文件的投标函盖有企业及企业法定代表人的印章,但没有加盖项目负责人的印章。
(5)E投标人与其他投标人组成了联合体投标,附有各方资质证书,但没有联合体共同投标协议书。
(6)F投标人的投标报价最高,故F投标人在开标后第二天撤回了其投标文件。
经过标书评审,A投标人被确定为中标候选人。发出中标通知书后,招标人和A投标人进行合同谈判,希望A投标人能再压缩工期、降低费用。经谈判后双方达成一致:不压缩工期,降价3%
问题

分析A、B、C、D、E投标人的投标文件是否有效说明理由。
