Question

Nowadays,you'll notice a phenomenon _______ a lot of people are wearing jeans to concerts.
A.where B.that C.if D.weather

Answer 1

B
that引导同位语从句修饰phenomenon.
这题主要看 phenomenon = a lot of people are wearing jeans to concerts,所以是同位语,必须用that引导.况且从句里面不缺成分,所以引导词不占句子成分,不能用where.至于if/whether,带进去意思不对,前面是phenomenon,后面不应该是疑问语气.
