请根据括号中的中文提示、英文释义或句意，写出句中所缺单词，使句子通顺。
【小题1】We students should do many after-school activities (活动).
【小题2】People in different countries speak different llanguages .
【小题3】It’s difficult (hard or not easy) for me to play basketball well because I can’t run fast.
【小题4】This boy doesn’t know the importance (重要性) of study.
【小题5】LLuckily , he wasn’t badly hurt yesterday.

解析：【小题1】考查固定短语。after-school activities“课外活动”。故填activities。【小题2】考查名词的复数。不同国家的人说不同的语言。故填languages。【小题3】考查形容词。difficult“困难的”。故填difficult。【小题4】考查词性转换。important的名词是importance。故填importance。【小题5】考查副词。副词修饰整个句子。句意“幸运的是，他昨天伤得不重。”故填Luckily。

我明天再问问老师，叫他解释下这个问题
