It is good to see that today more people have realized the importance exercising and are playing sports regular. But the problem is that there are not enough sports facilities to meet the public growing demand. I love playing basketball and often play with my friends on weekends. Therefore, it is difficult to rent a basketball field and impossible to find a free one. It seems that all courts in the city were always full. Weather permitted, we can play in outdoors. But on rainy days or in winter we have to turn to indoor courts. There are not much in my city, and the charge is expensive. The government should build more public sports facilities, so easier accesses will encourage more people to participate in sports.importance后加of
网友回答
(答案→)importance后加of
解析：
【小题1】 the importance∧exercising 锻炼的重要性，所以应加 of
【小题2】are playing sports regular。 副词修饰动词。regular改为 regularly
【小题3】meet the public growing demand 应该用名词所有格修饰demand，公众增长的需要。public改为public’s
【小题4】I love playing basketball and often play with my friends on weekends. Therefore, it is difficult to rent a basketball field 根据上下文此处应为转折关系Therefore 改为However
【小题5】It seems that all courts in the city were always full 文章叙述现在事情所以应用一般现在时态。 were 改为 are。
【小题6】Weather permitted, we can play in outdoors 此处没有连词，所以应是独立主格做状语，permitted改为permitting。
【小题7】we can play in﹨outdoors. outdoors 是副词，前面不用介词，所以去掉介词 in。
【小题8】we have to turn to indoor courts. There are not much in my city, 此处指的是场地courts，所以应用修饰复数名词的many 代替much。
【小题9】the charge is expensive。价格费用等词，不用expensive修饰，而用high或者low.
【小题10】so easier accesses will encourage more people to participate in sports. access “通道，接近的权利，机会”不用复数形式，比如 have access to .
