(16) ................. that is often the (17) ................. they are reported to be. The (18) ..................
"flying saucers" were seen in 1947 by an American pilot, but experts who studied his claim

Even people experienced at watching the sky, (19) ................. as pilots, report seeing UFOs. In
1978 a pilot reported a collection of UFOs off the coast of New Zealand. A television
(20) ................. went up with the pilot and filmed the UFOs. Scientists studying this
phenomenon later discovered that in this case they were simply lights on boats out fishing.
16 A because B therefore C although D so
17 A look B shape C size D type
18 A last B next C first D oldest
19 A like B that C so D such
20 A cameraman B director C actor D announcer

16、A （因为，因果关系，之所以称之为Flying saucer与之形状有关，由形状决定，而B表明这个称呼决定他的形状，不符逻辑）
17、B（形状 与前文flying saucers对应）

19、D(如飞行员一样）
20、A(摄影师，与下文film the UFOs对应）
