Question

A number of tourists ____ Yangzhou many times because it is such a beautiful city.

A． have been to

B． has been to

C． has gone to

D． have gone to

Answer 1

A

句中主語“a number of+名詞復數”表示大量的······ ，則謂語動詞要用復數。have been to表示去過某地（人已經回來了）；have gone to表示去了某地（人還沒有回來），根據句中many times“許多次了”可知要用have been to，所以選擇答案 A。
