答案与题解：
1.C该段主要是说，中国将帮助欧洲建立一个全球卫星导航系统。因此，作者整段使用了将来时。
2.A fund的意思是：to furnish a fund for（为……提供资金）。该句说，中国将提供二亿三千万欧元（二亿五千九百万美元））的资金。C和D在意思上不符合段意。
3.C A是错误的选项，因为伽利略（人造卫星）本身就是the major world infrastructure for the growing market for location services.B和D与句意不符。
4.D was also announced是被动语态，其后是动作的执行者the European Commission，the European Space Agency（ESA）和the Chinese Ministry of Science and Technology，所以应选择D.
5.B这个句子的动词was also announced是过去时，句子的意思是说，前不久，欧洲贸易委员会、欧洲航天局和中国科技部宣布成立一个新的中心，来协调合作事宜。因此，B是正确选项。A是错误选项，因为，虽然before也有与ago相同的意思，但是在用法上不一样，before与过去完成时一起使用。
6.D整个句子的意思是说该中心将设在北京大学内。be located at（或in）是正确搭配。
7.A interfere with是固定搭配，在这里的意思是：妨碍，干扰。
8.C这个句子说，美国对伽利略（人造卫星）持反对态度，是由于伽利略（人造卫星）对全球定位系统在商业上具有挑战性。选项A、B和D的意思都是“导致”，所以不符合句意。be due to的意思是“由于”或“由……造成”。
9.B这个句子告诉我们伽利略人造卫星群由27个运作卫星和3个储备卫星构成。B是“由……构成”的意思。选项A的be made from是“由……材料制造”的意思。选项C的consist in是“在于”或“存在于”的意思。consist of不能使用被动形式，所以选项D也是错误的。
10.D这个句子告诉读者，整个工程预计花费（cost）约32亿欧元。B和C与句意不符。选项A中的spend的意思是：to pay out（money）（花钱），一般用作及物动词，如：He spent 5 yuan on the book.而cost作为动词的用法一般是：The book costs him 5 yuan.The book costs 5 yuan.动词cost也没有被动态形式。
11.B wide-band signal called the Public Regulated Ser，ice（PRS）叫做公共调控服务系统的宽带信号。called在此是过去分词作后置定语修饰wide-band signal.12.A句子的谓语动词have said决定了主语应该是人而不是物。B是单数名词，不能用在这里。
13.B Clocks on board the satellite：在这架卫星上的钟表。这里的satellite特指前一句中的The first Galileo satellite，所以使用了定冠词，the.选项A、C和D的内容文中都没有出现过，所以是错的。
14.D通篇文章谈的都是定位系统，所以，地面接收借助定位系统来定位，应选location.其他三个选项（speed、direction、distance）都不符合上下文所表达的意思。
15.B从语法结构来看，只能选择B，闲为be relayed前没有动词不定式的形态标记to.
