It is natural that difficulties hide in every corner of our life,so we have to face them at times.Whatever we have undergone in our life, we shouldn't complain about it. We may get a lot or lose so much in our life journey, but keeping a positive attitude should always be together with us. Nothing can defeat us if we are confident and diligent. Just as saying goes, God is equal to everyone. As he closes the door, he will also open a window for us.

Many of us have seen a picture on the Internet of a man with a nice smile is struggling along with the aid of a stick because of losing one of his feet,and another man is sitting on the ground without shoes on his feet,looking anxious and depressed.How different the expressions flitting across their faces are!At the bottom of the drawing says”Because I have no shoes,I keep complaining until I find another man who has lost one of his feet.”

What an impressive drawing it is in revealing different attitudes toward life!A person's attitude towards life is very important, it determines your life, which path you are taking and how your life will become. if you are a person with very strong positive outlook, no matter what difficulties you encounter, you will always look at the bright side of life and never give up easily. Take Thomas Edison as an example.Before inventing the electric bulb,he had tried thousands of materials for lamp filament,but failed.Despite others’ laughing at him.he said,”I am not a failure,at least I have proved these materials are not fit for filament.”Before long he invented electric bulb.

The most frequent example you see are those patients or people that are handicapped or suffering from some type of illness like cancer. They do not give up any glimpse of hope and continue fighting till they their last breathe. Even those very determined handicapped,they do not blame the world for their disable. Instead, they are contented and blessed with all the rest the have, their family , friends and those who support them greatly. Those handicapped with negative attitude towards life will feel that the world is unfair and they life in misery and always feel that they are unless and unwanted.

All in all,it is our attitudes that have changed everything in our life and help us to pull through all hardships.So we should strive to develop a positive attitude toward life and the world.It is convinced that only when we are equipped with optimism and confidence can we achieve success in the future.

人教版英语教材是美式英语。

人教版英语教材一般是就教科书意义而言的，相对于其他出版社出版的教科书而言，指的是由人民教育出版社出版的教科书版本。而美式英语较英式英语来说更为口语化，读音开放，有特性。

过去的四百年间，美国、英联邦以及不列颠群岛使用的语言都在不断地发生变化，最终演变成了英式英语和美式英语。两种英语在音标、语法、词汇、拼写、标点、谚语、日期和数字的形式等等许多方面都有不同。

对于人教版的高中英语教材，单词拼写是按照英式英语标准来的，磁带录音用的却是美式英语。阅读材料里比较口语化的语言以美式英语居多。
