　　在线作业参考答案：

　　1.B see和look这两个词词义相关， 因此首先重点关注。空格前面出现了动词saw， 因此 B是答案的可能性较大。Look是不及物动词，而 see 既可用作及物动词也可用作不及物动词。空格处的动词是及物动词，引导定语从句的连接词充当从句中谓语动词的宾语， 因此B是答案。

　　2.C 四个词都是介词。其中below、underneath和under是方位介词，这三个介词互为近义词， 因此彼此排除掉， 因此答案只能是with。With所在的句子结构说...以碟子飞速掠过水面的移动方式飞着。

　　3.D 选项D是文章主题词的家族词汇，因此D可能是答案。第三段的第一句话 investigations found no evidence of visitors from outer space.)说军事调查并没有发现证据，可以说明从外层空间来了客人了， 由此判断空格处用visited上下文意义呼应。

　　4.A 空格处需要出现不及物动词， 因此首先排除D。 该句说不久由于出现了这么多的目击事件， 以至于美国军方开始..., 根据该句句意判断A出现在空格中最恰当。也可根据第三段第一个句子中的 military investigations的线索选择investigate。

　　5.C name和call是近义词， 都可以表示命名， 因此在命名这个词义上彼此排除掉，name虽然还有任命， 提名这样的词义， 但这样的词义放入空格中意义不通怎样被...的)，因此A和B都不是答案。 剩下的选项中选项C放入空格中意义通顺， 因此答案为C。

　　6.A 空格所在的句子说但是那不能阻止真正的...由此可以看出，最合适的词是believers。

　　7.B 只有cover可以跟up搭配。因此选择covering。Cover up是固定搭配，其含义为掩盖。

　　8.D 备选项中A， B和C词义接近：都可以表示肯定地， 因此彼此排除掉， 答案只能为D。 其实空格所在句子的第一个词是or，表示两种情况都有可能，因此只有用maybe在语义上才是一致的。

　　9.C 根据空格所在的局部结构were explained in ...ways/以...的方式被解释判断B出现在空格中不合适。借助接下来的句子In a world where religion was less influential，判断合适的选项是religious。

　　10.A 本文的主题是讲不明飞行物，也就是讲来自外星球的人，因此合适的选择是planets。其实接下来的一句中就出现了sign的家族词汇signing。

　　11.D 正确地回答这道题需要有一点世界知识。第二次世界大战结束后冷战开始，因此选择cold是正确的。星球大战的提出是里根。核战争如果会发生的话，文明早就消失了。cold war是冷战。

　　12.B look above是从...往上看。 look to是依赖。Look to...for... 是指为了...而指望...。因此to是合适的选择。相关的句子说的是：跟先辈们一样，人们乞求老天来帮助他们。look at是看， Look up是往上看，查寻 。 look up是一个干扰项，look up在表示往上看， 好转时是不及物动词性的短语结构。

　　13.D 空格所在的局部结构说aliens with ...technology/有着...技术的外星人， 由此判断D是答案。

　　14.C 与空格所在的句子并列的句子说：宇宙是一个很大的地方。从这句话可以推出，我们有理由假设在那儿有生命的存在。因此，选reasonable是对的。

　　15.A 根据空格所在的局部结构experiments...on them/在他们身上...的实验判断A是答案。
