163 Because Halley’s comet changes orbit slightly during the seventy-six-year interval between passing close to Earth, it may veer onto a collision course with a planet sometime in the distant future.
(A) between passing
(B) of passing
(C) between its passes
(D) of its passes(C)
(E) as it passes这题看以前的讨论连接只提到interval between 是固定的,发现是有interval between,但后面都有and的,eg:
the interval between a lightning flash and the following thunder
an interval of 50 metres between posts
the interval between greatness and meanness/master and servant,想请教下这里interval between 的用法,另外为何A不对,between是 prep,后面为何一定要补齐??
这题的interval between应该是固定用法, 从中文角度理解也是"间隔"的意思, 所以这个between应该是不可缺少的.
这题涉及一个主语清晰的问题, A只说了between passing, 但是谁去passing没有说, 忌讳!
