We all have some keys in life，some visible and othersinvisible．In our daily life，it’s necessary and convenient for us to take thevisible ones．If we are careless to lose them，we’ll feel upset and our lifemay be troublesome．（有形的钥匙）
．In fact，some invisible keys are also important to us in ourlife．As students，we study at school every day．By listening to the teachers，we own a key to research and discussion，and to learning how to get knowledge．Through reading，we get a key to opening the door of mystery and sharing theideas of great people of the past and the present．From writing，we have a keyto tapping the potential of our own，finding another colorful world andrealizing a meaningful way of learning and living．【高分句型】（无形的钥匙）
In a word，the two kinds of keys are equallynecessary in our life．To us students，it’s perhaps more important to own a keyto opening the gate of wisdom．【高分句型】（总结概括） We all have some keys in life，some visible and othersinvisible．In our daily life，it’s necessary and convenient for us to take thevisible ones．If we are careless to lose them，we’ll feel upset and our lifemay be troublesome．（有形的钥匙）
