5._____ there are two different results,scientists now generally agree that some kinds of dinosaurs lived in big groups.( 。
A.ThoughB.IfC.As long asD.Unless

分析 盡管有兩種不同的結(jié)果,但是科學家現(xiàn)在普遍認為一些種類的恐龍是群居生活的.

解答 答案:A.
根據(jù)句意"盡管有兩種不同的結(jié)果,但是科學家現(xiàn)在普遍認為…",可知,前后存在著邏輯上的一種轉(zhuǎn)折關系,所以用though來引導;故選A.

點評 本題考查從屬連詞的用法.連詞的用法辨析,要注意分析主從句之間的邏輯關系,再確定相應的連詞,同時注意不同的連詞的語義及用法區(qū)別.
