Trying to make some sentences, please correct my sentences! 1. Since I went hiking last weekend, my lower legs (my calves) still ache, because I didn't stretch my muscles after exercise. So I have to give up(have to skip) going to the gym tonight. 上周徒步后，小腿肌肉一直感到酸痛，因为运动后我没有拉伸肌肉, 所以今晚不得不放弃去健身房。 2. I don't often wear sandals even in summer. 即使在夏天，我也不常穿凉鞋。 3. Most foreigners find it incredible that no one steals packages left on the street side in China. Stealing is a shameful behavior. It's moral red line, and no one wants to cross it. Normally when we talk about a "line" like in this context, it's more natural to talk about crossing or not crossing it. 对于很多外国人来说，他们难以置信，路边放着这么多包裹，既然没人去偷。在中国偷盗是可耻的行为，是道德红线，没人想去做。
