4.On June 24,1947,a US pilot named Kenneth Arnold looked out the window of his plane and saw nine silver objects flying close together.
(66)C Kenneth guessed that their speed was more than 1,600kilometres an hour.He told journalists that the objects did not move like planes,but like saucers(碟状物) move when someone throws them across the surface of water.Later one of the journalists called the objects"flying saucers".
This was the first time the expression"flying saucer"was used,but people have seen UFOs (unidentified flying objects) in the sky centuries ago.For example,in the thirteenth century some English farmers saw a flat,(67)D This is surprising because in those days there were no planes,weather balloons,or space stations that could be mistaken for UFOs.
Today,many UFOs turn out to be something quite ordinary.(68)B eight colored lights appeared in the sky above Kuala Lumpur in Malaysia.The lights seemed to float in the air for ten minutes before moving off and disappearing.(69)E They turned out to be good luck lanterns(灯笼) that had been released from a temple.
Most UFOs can be explained like this.(70)A surveys show that at least half of us believe intelligent life exists on other planets.Is it possible,therefore,that someone from"out there"is visiting us?

根据材料内容,从下面五个选项中选出能填入文中空缺处的最佳选项,使短文意思通顺,内容完整,并将其称号填写在下面题号后的横线上.
A.There are many
B.One evening in February,2001,
C.They were moving very quickly.
D.silver object in the sky.
E.Many people thought they were UFOs.

分析 文章大意:这是一篇议论文,主要介绍不明飞行物.不明飞行物像盘子在水面上旋转一样飞行,因此最开始被称为飞碟.很多人看到过不明飞行物,有的其实是一些灯笼、气象气球等.但很多是不能解释的.很多人认为智能生命存在于其他行星上.也许会有外星人来拜访我们.

解答 66.答案:C.选句题.根据下句Kenneth guessed that their speed was more than 1,600kilometres an hour.肯尼斯猜想他们的速度是每小时超过1600公里.可知,上句应该是"它们移动得很快.",选C.
67.答案:D.选句题.根据下句This is surprising because in those days there were no planes,weather balloons,or space stations that could be mistaken for UFOs.这是令人惊讶的,因为在那些日子里没有飞机,气象气球,或空间站,可能被误认为不明飞行物.可知,上句应该是一些英国农民在"天空中看到一个扁平的银色物体".选D.
68.答案:B.选句题.根据下句eight colored lights appeared in the sky above Kuala Lumpur in Malaysia.八个彩灯出现在吉隆坡马来西亚的天空.可知,应该是在晚上的时候.上句填"2001年2月的一个晚上",选B.
69.答案:E.选句题.根据下句 They turned out to be good luck lanterns(灯笼) that had been released from a temple.他们原来是从寺庙释放幸运的灯笼.可知,应该是误以为是不明飞行物.上句填"许多人认为它们是不明飞行物.",选E.
70.答案:A.选句题.根据下句surveys show that at least half of us believe intelligent life exists on other planets.调查显示至少有一半的人相信其他星球上存在智慧生命.可知,surveys调查,复数.应该是"有许多"调查.选A.
