重点全解
1. Kitty and her family have gone to Hong Kong.
family作可数名词,意为“家,家庭,家人”。其复数形式要变y为i,再加-es,即families。
family(单数) His family is big. 他的家庭是一个大家庭。
family(复数)His family all like reading. 他们全家人都喜欢读书。
注意
family是集合名词,作主语时,若指家庭这个集体,则谓语动词用单数形式;指家庭成员时,被视为复数,谓语动词要用复数形式。

at the moment为介词短语,相当于now,意为“此刻;现在”,用于一般现在时或现在进行时的句子中,作时间状语,其中moment为可数名词,意为“瞬间;片刻”。
例如:
I have nothing to do at the moment. 现在我无事可做。
We are watching a movie at the moment. 此刻我们正在看电影。
【拓展】at that moment意为“在那时候”,用于一般过去时或过去进行时。
The girl was washing her clothes at that moment. 在那时候,那个女孩正在洗衣服。

see sb. do sth.
