吃过晚饭，我在书上看到了定滑轮构造，对此非常感兴趣，我就想到了用乐高搭一个起重机也许很不错。
After dinner, I read about the fixed pulley structure in a book and was very interested in it. So I thought of using LEGO to build a crane, which might be great.
说干就干！当我拿出我的乐高积木组合和带钩子的线时，信心满满的我一下子又失望了，因为我发现积木组合里面并没有定滑轮。怎么办呢？首先我在大脑里构思了一下起重机大概的样子。突然，我灵机一动，发现可以用积木红八洞来代替定滑轮，用带钩子的线一头穿过它中间的洞，另一头加上摇柄组合。这个摇柄组合可是我的新发明。我把白小棒从黄四洞中间的一个洞里穿过去，一头接上摇柄，另一头装上卡螺，再系上钩子线，就可以来控制钩子的升降了。
Just do it! When I took out my LEGO block set and the wire with hooks, I was full of confidence and suddenly disappointed because I found that there were no fixed pulleys in the block set. What shall I do? Firstly, I imagined the general appearance of a crane in my mind. Suddenly, I had an idea and realized that we could replace the fixed pulley with a red eight hole block. We could use a wire with a hook to thread one end through the middle hole and add a handle combination to the other end. This handle combination is my new invention. I threaded the white stick through one of the holes in the middle of the Yellow Four Holes, connected one end to the handle, installed a locking screw on the other end, and tied the hook line to control the lifting and lowering of the hook.
所有零件齐全后，我开始按照从下往上的顺序把起重机拼搭起来，从底座到机身，每一步都不容易，不是材料不够，就是钩子放不到底。这时，妈妈走了过来，安慰我说道：“这个太难了，也许这么点材料不够用，你还是去玩别的吧。”我摇摇头，继续拼搭起重机，因为我相信只要不放弃，坚持下去一定能成功。
After all the parts were complete, I started assembling the crane from bottom to top, from the base to the body, every step was not easy, either due to insufficient materials or the hook not being able to fit all the way. At this moment, my mother walked over and comforted me, saying, "This is too difficult. Maybe this little material is not enough. You should go play with something else." I shook my head and continued to build the crane, because I believed that as long as I didn't give up and persisted, I would definitely succeed.
功夫不负有心人，在我的坚持努力下，一个有模有样，可以升降，吊物的起重机模型终于拼搭成功了。我开心地把起重机展示给妈妈看，妈妈赞许地对我竖了个大拇指。
Hard work pays off. With my persistence and hard work, a model of a crane with a model and shape, capable of lifting and hoisting objects, has finally been successfully assembled. I happily showed the crane to my mother, and she gave me a thumbs up approvingly.
