如今,茜已经15岁了,茜的奶奶与他们住在一起。奶奶年事已高,活动渐渐不那么灵便了,却不知为何,奶奶闲来无事时竟喜好在小区街道附近拾一些易拉罐、矿泉水瓶等废品带回家,堆积在杂物室 Now, you are 15 years old and your grandmother lives with them. The grandmother is old and her activities gradually become less agile, but I do not know why. When my grandmother has nothing to do with her time, she likes to pick up some cans, mineral water bottles and other waste products near the streets of the community and take them home to accumulate in the debris room.
