求助

     1，surprising to many,England has one of the highest population (density) in the world .

不明白density 如何该？

      2，after the first celebration of Earth day in 1979,(considerable) (interesting) devoloped among young people ,who used the event to show outrage at the way we were treating it.

括号处的两词明显看着别扭，可我就是不知如何改？而且整句话的意思我好像也不是很明白？

      3 ，An electric car`s battery can allow a car to cover (distance) of 250 km before needing to recharge.

distance 应该改为 distances。

我想问的是：什么时候用“a distance of ---”呢？----我记得以前在那见过

还有，句尾“needing to recharge“为何不是被动时态？

1，surprising to many,England has one of the highest population (density) in the world .

改错吗？应该改为复数吧。densities. 因为句中说 one of the ... 所以后面的名词要复数。

2，after the first celebration of Earth day in 1979,(considerable) (interesting) devoloped among young people ,who used the event to show outrage at the way we were treating it.

红色部分为句子主干，可以看出来缺主语。觉得应该把interesting（形容词） 改为 interest

第三题，个人认为应该用 a distance of ， 再查查，或等待高人回答。
