这个英语题为什么选A不选D
It was about 600 years ago ( )the first clock with a face and an hour hand was made.
A that
B until
C before
D when
It was about 600 years ago ( )the first clock with a face and an hour hand was made.
A that
B until
C before
D when
看从句：the first clock with a face and an hour hand was made.
是一个不完整的被动句.
所以要用that（关系代词）来补充完整.
when是关系副词,如果从句时一个完整的句子（主谓宾/主系表/……皆全）才用
改
it + be动词 +that 构成强调句.
第一次我看错了.
