I’m a senior 3 student. The college entrance exam is on the way .Everyone around us is trying their best to help us in different ways. At school, our teachers work very hard, encourage us to deal with problems .Whenever we meet with difficulties, they are ready to help us. Meanwhile, our school also provides good facilities for us, for example the library stays open in the evenings and even on the weekends. At home, our parents take good care of us and make sure we are well fed so that we can always be full of energy.
I’m very grateful for the efforts of our parents and teachers. I’m determined to try my best to prepare for the exam. I am sure I will be successful with their help.
面临高考，考生对此题材熟悉，有话可说；把握：老师，学校、家长、你自己四方面的内容；然后发表看法。重点放在后边，注意分段和过渡。
