　　答案解析：

　　1.C。从上下文语境来看，中国将帮助欧洲建立一个全球卫星导航系统，而且整段多使用将来时。

　　2.A。从上下文语境来看，中国将在__________ 方面提供2.3亿欧元(2.59亿美元)。四个选项分别代入，只有funding(基金，资金)符合语境，其他三个选项：providing(提供)，paying(付账)和charging(收费)在意思上均不符合。

　　3.A。从搭配来看，只有build the infrastructure(建设基础设施)是对的。

　　4.D。这里考查的是被动语态。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)$W the Chinese Ministry of Science and Technology，故应选择bv。

　　5.B。这里考查固定短语(not)long ago(不久之前)，long before(不久)。从上下文语境来看，not long ago符合语境，本句意为：不久之前，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。

　　6.D。这里考查的是习惯搭配，be located at/in(位于……)，从上下文语境来看，该中心将设在北京大学内。

　　7.A。这里考查的是习惯搭配，interfere with(妨碍，干扰)是固定搭配。

　　8.C。从上下文语境来看，美国对伽利略(人造卫星)持反对态度，是由于伽利略卫星系统对全球定位系统在商业上提出挑战。选项A、B和D的意思都是“导致”，所以不符合句意。bedueto的意思是“由于”或“由……造成”，符合文意。

　　9.B。从上下文语境来看，伽利略卫星系统由27个运作卫星和3个储备卫星构成。B项consist of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，存在于”的意思。consist of不能使用被动形式。

　　10.D。从上下文语境来看，整个工程预计花费(cost)约32亿欧元。8和C与句意不符。选项A中的spend为及物动词。cost作为动词的`用法为sth.cost(sb.)sth.，没有被动态形式。

　　1 1.B。wide-band signal called the Public Regulated Service(PRS)中的called在此是过去分一词做后置定语，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。此外，B项是单数名词，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，只有let sb.do sth.是正确的。
