In the phrase “the mouth of the river’’，the word “mouth”
is( ) motivated.
【正确答案】：SEMANTICALLY
【题目解析】：Semantic motivation refers to the mental associations suggested by the conceptual meaning of a word. When we say ,"the mouth of a river", we associate the opening part of the river with the mouth of a human being or an animal.语义理据是指由词的概念意义所暗示的联想意义。在说the mouth of a river时，我们是把河口与人或动物的口联系起来的；所以mouth在短语中属于语义理据。答案为semantically。
