英语疑难问题
用合适的关系词填空：
1.This is the first letter--------I've received from him since he left.
2.1969 is the year------my sister was born.
3.China is the country------he visited last year.
4.The actress --------hair is golden is my aunt.
5.The cause---------he failed in the experiment is not clear.

Answer 1

1.that或不填
关系词代替先行词letter,做received的宾语,可以省略不填；
关系词被序数词first所修饰,如果填的话,只能使用that
2.when 或 in which
when = in which = in the year,在定语从句my sister was born中充当时间状语.
3.which/that或不填
关系词代替先行词the country,做定语从句中visited的宾语,指物,可以用that或which,当然也可以省略不填
4.whose
whose = the actress',在定语从句中充当hair的定语.
即：whose hair is golden = the actress' hair is golden
5.why
why在定语从句he failed in the experiment中充当原因状语.
