Monday: Here I am, in the middle of nowhere. This camping trip idea is not getting off to a very good start. It’s raining and the tent leaks. The hiking seemed to take forever, and I still can’t understand how it could all have been up hill! How did I ever let my brother talk me into this? When we get home—if we ever get home—he’s going to have to do something great to get back on my good side. Maybe he should sponsor a shopping spree（狂购）at the mall!

Tuesday: Things are looking up. The sun came out today, so we were able to leave the tents and dry out. We’re camped at the edge of a small lake that I couldn’t see before because of the rain and fog. The mountains are all around us, and the forest is absolutely beautiful. We spent most of the day dragging out everything out of our backpacks or tents and putting it where the sun could dry it out. Later in the afternoon we tried to catch the fish for dinner, but the fish were smarter than we were. At night we built a fire and sang songs happily.

Wednesday: We hiked to the far side of the lake and climbed to the top of a small peak. From there we could see how high the other mountains were and how far the forest spread around us. On the way up we passed through a snowfield!

Thursday: I caught my first fish! We followed the stream that fed the lake. After about two miles, we came to a section that Carol said looked “fishy”. She had a pack rod(竿), which can be carried in a backpack. I asked to cast it, and I caught a fish on my first try. Carol caught a few more. But they were just too pretty to eat for lunch so we put them back in the stream.

Friday: I can’t believe we are going home already. It will be nice to get a hot shower, sleep in a real bed, and eat junk food, but the trip has been wonderful. We’re already talking about another camping adventure next year where we canoe down a river. It’s hard to believe, but I think this city girl has a little country blood in her veins.

某企业员工薪酬构成主要包括：岗位工资、月奖金、年终奖金。月奖的标准是根据岗位等级而定的，职级越高，奖金越多。月奖与考核不挂钩，实际上是工资的补充。年底奖金：管理部门如财务部的年底奖金是年底双薪，业务部门的总奖金是按部门业绩提成的，但有时不能兑现。 业务部门员工的奖金是背靠背的，由部门经理发放，员工不知道发放的依据。由于原有的方案存在许多问题，需要重做。 结合案例，设计一个合理的薪酬分配方案。
