^令x=1,则a(0)+a(1)+a(2)++a(2n-1)+a(2n)=(1+2)^(2n)=3^(2n),
令x=-1,则a(0)-a(1)+a(2)-a(3)++a(2n-2)-a(2n-1)+a(2n)=(-1+2)^(2n)=1,
a(1)+a(3)++a(2n-1)=(1/2){[a(0)+a(1)++a(2n)]-[a(0)-a(1)+a(2)-a(3)++a(2n)]}
=(1/2)[3^(2n)-1]

秋游是我从暑假就开始盼望的事，我相信大家也都这样吧，秋游可以大家一起出去玩，那是多么幸福呀！想着想着，我对秋游的欲望越来越多了。
星期二下午刚下课，我们正收拾着书包，准备放学，老师拿着一堆通知，一组一组的发，发到我这一组，我看见了通知，差一点大叫起来，是秋游！是秋游！我蹦了起来，和同学交头接耳，我们五到六年级去的是长鹿农庄，听说那里很刺激，连有个鬼屋都把我同学的妈妈的同事给吓哭了，我听见后都迫不及待想到那里了！
星期三下午，爸爸带我去买秋游要用的食物，我进到市场，心中流出一种兴奋感，还没秋游就兴奋了，我把要买的东西写下来，一个一个开始买，先是薯片，还是要美国乐事原味的！再是巧克力，然后再是糖果......我逛遍了整个市场，转来转去，推着手推车，到付钱台付钱。
出了市场门口，我拿着大包小包的，蹦蹦跳跳走去车上，刚要开车门，爸爸接到一个短信，他看见后，笑了笑，对我说："哈哈，刚买完东西，现在完咯！＂我问爸爸：＂怎么啦？？＂爸爸说：＂你自己看＂我接过手机，上面是杨老师发过来的短信，写着：因考虑到明天下雨的关系，明天的秋游改道下个星期二，请及时通知孩子。我看到短信后，崩溃了，我简直太生气了，怎么会这样！我的欲望就这样消失了。我可刚刚买完东西阿！
今天是本来是应该秋游的星期四，我到了三楼，就看到二班有一群男生再走廊上喊：＂还我秋游！还我秋游！＂我看见后，我没理他们，但我在心中也跟着他们一起呐喊着：还我秋游！

My View on The Advantage of Keeping Pets
When it comes to the topic of keeping pets, some may think it is a waste of both time and money; some people, may find it is a great joy. As for me, I hold that keeping pets can bring me happiness.
Firstly, keeping pets can keep us company when we feel lonely. As we know that it is impossible for us to stay with others all the time, and sometimes we have to stay all by ourselves. At this time we may feel lonely, if you have a pet, it will help to keep company with you. You can play with your pet and regard it as your friend.
Secondly, keeping pets makes our world more harmonious. Animals are good friends to us human beings; it will make our world more harmonious to build friendship with them.
Last but not least, keeping pets makes us more patience. Animal needs careful cares, and we need bath them, feed them and take them out every day, which is time consuming. If we have a pet and can do that every day, we will become more patient.
In a word, keeping pets can keep us company, make our world more harmonious and make us more patient, so I think it is a great for us to keep pets.
