1.the lady was taking a long time to order and _asking__ the man questions。she was dressed like a person who __has been living on street this month . maybe she was homeless and was having a hard time placing her order in a place with limited choices on the menu_because___this was already more choice than she had ever had in her life
请问语法填空为啥是asking而不是ask 。take sb some time to do and do 结构啊。 第二个空为什么不是had been living 叙述者是过去时态was dressed like 所以要had啊？第三个空为啥不是though?这位女士很穷（所以though)即便订单选项足够多了，她仍然觉得很难选择，太贵了，
承前省略了was
后面的this month本月，至今还没结束。
第三空该填though吧【尽管菜单上已有她有史以来最多的菜肴】
1所以第一个也可以用ask对吗take sb some time to do and do
2 但是现在完成时不是表示现在时描述吗。比如i love china.i have been linving in china since 1919。 假如i loved(过去表述） china.i had(改成过去式保持句式状态一致性） been linving in china since 1919
3.答案上只写了since,as,because三种，没有写though
