俩句子，各有一处错误，请改正……囧

It costs me lots of time to take photos.
物做主语应用cost
人才用spent

Do you know if Sally has arrived in Beijing?
北京是地区（大）
用IN
小地方如房间等用at

It (takes) me lots of time to take photos.

Do you know if Sally has arrived (in) Beijing?

it takes me lots of time to take photos.只有人做主语才能用spend这个动词

do you know if Sally has arrived in Beijing?小的地方用at,大的地点用in

spends改成costs

if 改成whether

It spend me lots of time on taking photos

Do you know whether sally has arrived at Beijing?

costs 替代spends
at 换成 in
