[背景资料]
某城市轻轨工程的建设单位自行办理招标事宜。由于该工程技术复杂,建设单位决定采用邀请招标,共邀请A、B、C三家国有特级施工企业参加投标。
投标邀请书规定:6月1日至6月3日9:00—17:00在该单位总经济师室出售招标文件。
招标文件中规定:6月30日为投标截止日;投标有效期到7月20日为止;投标保证金统一定为100万元,投标保证金有效期到8月20日为止;评标采用综合评价法,技术标和商务标各占50%。
在评标过程中,鉴于各投标人的技术方案大同小异,建设单位决定将评标方法改为经评审的最低投标价法。评标委员会根据修改后的评标方法,确定的评标结果排名顺序为A公司、C公司、B公司。建设单位于7月15日确定A公司中标,于7月16日向A公司发出中标通知书,并于7月18日与A公司签订了合同。在签订合同过程中,经审查,A公司所选择的设备安装分包单位不符合要求,建设单位遂指定国有一级安装企业D公司作为A公司的分包单位。建设单位于7月28日将中标结果通知了B、C两家公司,并将投标保证金退还给该两家公司。建设单位于7月31日向当地招标投标管理部门提交了该工程招标投标情况的书面报告。

解答题
完形填空
Africans see many advantages by uniting the continent into a single nation, or by uniting several small nations of a particular region into a nation. In unity there is strength. Africans often point to the United States, formed by the original 13 states, as an example of this principle. Africa now is divided into many weak nations. United, they would be much stronger. Africans could then more easily deal with foreign efforts to control them. Also it would be easier to plan and carry out big projects like the building of highways and dams.
The considerations for African unity go beyond the practical advantages it brings. As we have seen, one factor is that the feeling of belonging to a particular nation is not strong among Africans. If, for example, you were to ask a man from Paris " What are you?", he would certainly answer " A Frenchman". Ask the same question of a man from Ibadan in Nigeria and he might give one of three answers, or all three, depending on his education and outlook. He might say, " A Yoruba" (his people), or " A Nigerian," or just simply " An African."
Another factor that enters into the desire for unity is that African leaders throughout the continent feel that they all have many things in common. They all lived through the experience of colonial rule. Many of them went to school and university with men who now lead other African countries. They all feel very angry about the way in which they were treated in the past. Compared with these strong bonds (结合),which overshadow the borders of nations, the idea of building separate nations does not have so much meaning. Some leaders say they are ready, in fact, to give up their separate nations.
Many nations have written into their constitutions(宪法), and they may give up their powers to a Pan-African government that will come into being.
