Question

years ago we didn't know this,but recent science ____that people who don't sleep well soon get ill.
a showed.b has showed.c will show.d is showing.
还有一点 soon不是副词吗 在句中是不是修饰 get ill?

Answer 1

选B,不应该是过去时,因为后面的从句是现在时,而且years ago只管到逗号那里就行了.
soon 是副词,修饰后面的get ill.前面的who don't sleep well 是定语从句,修饰前面的people.也就是说
recent science has showed that [ people (who don't sleep well ) soon get ill.]
[ ]中的是宾语从句,（）中的是修饰people的定语从句
