题目内容
19.The Mekong River Commission has found no evidence ______ the dams on the upper reaches have an influence on the water flow downstream.( )A. | which | B. | that | C. | where | D. | what |
分析 湄公河委员会没有发现证据,上游的大坝对下游的水流有影响
解答 答案:B.根据the dams on the upper reaches have an influence on the water flow downstream可知整句是前面evidence 证据的内容,没有发现上游的大坝对下游的水流有影响的证据,是同位语从句,故选C.
点评 本题考查同位语从句,注意区分其与定语从句,定语从句前面的名词即先行词在后面定语从句中需充当成分,而同位语从句是对前面名词的补充说明.
