    I'm Sarah. I have five new teachers. Miss Wang is our Chinese teacher. She is young. She has short hair and big eyes. Miss Li is our art teacher. She is young. She has long hair. And she is very kind. Mr Gao is our maths teacher. He is old and he is short. He is kind, too. Mr Liu is our music teacher. He is very strict. We are all afraid of him. Mr Zhang is our science teacher. He is young. He is kind, too. We all like him.

 What is time? 

 What is time? Nobody s____ it and nobody catches it. But everyone can feel it passing by. Time is always with us in life. W____ we are at table. Time passes by. When we talk, time slips away(溜走) in front of us. And when we p____ with friends, time goes by unnoticeably (不引人注意地). Time is fair to every one of us. I____ you make the best of it, time will give you a lot. Otherwise (否则)you will miss a lot. The most important(重要的) is that time will not be found again. Time is becoming more and more important to us today. You can always hear people say, "Time is m____, Time is life". It warns us not to waste (浪费)any time.
