核心问题

A. increased B. increased by C. increased with D. increased to

《中学英语答疑析难》(高三)(p.91)解答说,此题答案只能是B,并且认为increase by n timesincrease n times意思不同。请问此题真的不能选A吗?

词典解答

英语里既可以说 increase by n times, 也可以说 increase n times。在一般情况下, 两者的含义是相同的, 都表示“增加到 n 倍”或“增加了 n - 1 倍”(参见 n times more than, as much as)

  1. Foreign investments there increased six times. 那里的外国投资增加了5倍。

  2. The steel output has increased by two times. 钢产量已增加了一倍。

  3. The strength of the attraction between two unlike charges increases by 2×2=42 \times 2 = 4 times if the distance between the original charges is halved. 如果两个不同的电荷之间的距离缩短一半, 则它们之间的吸引力的强度增加到原来的 2×2=42 \times 2 = 4 倍。
