　　参考答案：

　　51　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。

　　52　A fund的意思是：to furnish a fund for。该句说，中国将提供二亿三千万欧元的资金。C和D在意思上不符合段意。

　　53　C A是错误的选项，因为伽利略本身就是the major world infrastructure for the growing market for location services。B和D与句意不符。

　　54　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和the Chinese Ministry of Science and Technology，所以应选择D。

　　55　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。

　　56　D整个句子的意思是说该中心将设在北京大学内。be located at是正确搭配。

　　57　A interfere with是固定搭配，在这里的意思是：妨碍，干扰。

　　58　C这个句子说，美国对伽利略持反对态度，是由于伽利略对全嘲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。

　　59　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。

　　60　D这个句子告诉读者，整个工程预计花费约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，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。

　　61　B wideband signal called the Public Regulated Service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wideband signal。

　　62　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。

　　63　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 Galile0，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。

　　64　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。其他三个选项都不符合上下文所表达的意思。

　　65　B从语法结构来看，只能选择B，因为be relayed前没有动词不定式的形态标记to。
