1.best known for "the" rolling hills
2.I "believe" the first feature I will describe" in...(suppose represents a kind of uncertainty,not suitable for this situation)
3.when I "stand" (wrong spelling here) "on the hill and overlook the city",I "am" (should have a verb here) always astonished "by" the view.
4.also,light trails (no the) "are" widly used in my hometown .不知道你用light trail是指的什麼,似乎没有这种交通工具,改用tram/train比较好.
5.i believe/think (not suppose) it is a very convenient (wrong spelling here) "transportation" and it can help people save (should use bare infinite here after "can") much time.
6.Another siginificant characteristic "of the city" is the delicious food which attracts (change the pattern of the sentence,but the original sentence has nothing wrong)...
7....I also believe the style (not color) of (not in) this kind of food may represents the local people of hot personality.
