1.with the help of the computer ,the day has come __we can workat home
A.in which B.when
【为什么答案是B,还原之后不是”we can work at home in the day 为什么不选A】
2.we'll put off the trip until next week____the weather will be fine.
A.at which B.when
【同样的,为什么答案是B?the weather will be fine at next week.这样说,不应该是A吗?】

1,B.when 是正确选项.
这是定语从句,先行词the day,从句不缺主语和宾语,故要用关系副词,且先行词是表示时间,要用when.把句子的顺序改一下,你可以看到很清楚：With the help of the computer ,the day when we can work at home has come.不能用in which,它=where,是属于地点类的关系副词；
2,B.when
本题与第一题如出一辙,先行词the week,是时间名词,关系副词要用when,不能用in which,更不能用which
定语从句中,凡是时间名词做先行词,而从句又不缺主语和宾语时,关系副词都要用when,而没有用in / at which代替when的说法.只有先行词是地点名词,才能根据实际情况用in / at which代替where.
