核心问题
San Francisco is usually cool in the summer, but Los Angeles ____.
A. is rarely B. rarely is C. hardly is D. is scarcely(全国四级,91.6-57)
您在 always , never 条中说过, rarely 等副词应放在实义动词之前、助动词和连系动词之后。而上题的答案却是 B(rarely is)。我认为答案应为 A。
词典解答
在 always 和 never 各条中所讲的都是正确的。只是这里应当补充一句: 在省略句中, rarely 等频率副词则必须放在助动词(包括情态助动词)和连系动词 be 之前。上题中的 but Los Angeles rarely is 便是一个省略句。再如：
Kunming is usually cool in the summer, but Shanghai ____.
A. is rarely B. scarcely is C. hardly is D. rarely is(全国研考)
