问题 Professor Johnson is said to have made some ______ advance in his research in the past year.

选项 A、extensive
B、significant
C、fundamental
D、dominant

答案B

解析 语义连贯题。所填词修饰advance,[B]significant“重要的,重大的”指某事特别有意义或优秀而显著,significant advance表示“重大的进步”,符合句意,所以[B]为答案。[A]extensive“广泛的,广大的”;[C] fundamental“基本的,基础的”;[D]dominant“有统治权的,占优势的”。
