秋天，是一年四季中我最喜爱的季节。
秋天真是秋高气爽，大雁南飞! 你看大雁正排成人字向南方飞去，还有一大部分的叶子都变黄了，被风轻轻一吹就落下来，犹如蝴蝶在半空中翩翩起舞；地上的小草都睡着了，等待明年春天再换绿色的衣服，绚丽多彩的小花都变黄了，只有菊花还在那晒太阳。
秋天更是一个丰收的季节啊!
田野里一株株水稻挂满了金黄的稻谷，弯着腰，好像在给凉爽的秋风鞠躬行礼，远远望去像大地爷爷铺的黄金色的地毯。有位老爷爷正拿着一把镰刀，在辛辛苦苦地割着金灿灿的稻子，个个汗流浃背的。秋天果园的果子熟了，一棵棵橘树挂满盏盏黄金色的小灯笼，苹果树上的娃娃在树上偷偷地笑了；最引人注目的是那棵柿子树，橘黄色的柿子形状不大，挂在树枝上，使人最爱，恨不得马上咬上一口，有的柿子不熟就管吃。我一会儿去摘橘子，一会儿去摘苹果，会儿去摘柿子，摘了如几筐。
秋天真是美啊! 我最佳

甲型H1N1流感的一篇文章，急！

要应对“甲流感”必先了解“甲流感”
从4月以来，一场“甲流感”正在席卷全球，随着感染人数的不被刷新，该如何让应对这场疾病的传播，我想是每个地球人都要思考的问题。
回顾历史，当人类在面对一种新的病毒来袭时，总是或多或少的表现出些许恐慌。比如这场“甲流感”让多少人身陷惶惶不安中。其实，这也很正常，毕竟这个病毒是新一代的，人类对它知之甚少，无法预知它，更无从控制它。不过，我始终报以乐观的态度，我始终相信这“不可知，不可控”的局面一定是暂时的！很快，聪明的人类一定能找出它出没的规律，从而，遏制它的肆意蔓延！
这不，我们已经知道了，“甲流感”是一种急性呼吸道传染病，通过飞沫，接触等方式，可以人传染人，其症状和其它流感类似，一般是高热、咳嗽，浑身没力气，与普通流感不同的是，H1N1流感主要攻击群体是25岁-45岁的青壮年。介于这次H1N1病毒的传播途径，建议大家在地铁、车站等人群密集场所必要的时候可戴口罩，起到对病毒的拦截作用。
另外“甲流感”曾被叫做“猪流感”，这其实是是种误解，虽然，现在监测到的病毒是禽流感、人流感和猪流感病毒基因片段的混合体，不过，从所有的患者病史来看，都没有和生猪的接触史，而且在生猪当中也没有分离出这种新型的变异病毒。因此，憨态可掬的猪，这回彻底的背了次黑锅！
现在，“甲流感”的预防疫苗被研制出来，但据目前的一些情况来说，确诊的被感染者，发病最初72小时是最佳救治期，主要吃“达菲”和“瑞乐砂”两种药就能对病毒起到很好的抑制作用。
当然，所有的疾病传播都是可以防控，“甲流感”也不例外，我们可以通过勤洗手、勤通风、少扎堆、早发现、早隔离等方式来减少病毒的传播可能。比如，在乘坐封闭、拥挤的交通工具，最好将车窗打开，保持空气流通，降低病毒密度；再比如，在进餐前记得用肥皂等清洁剂把冲洗双手干净；还有，多关注媒体上对疫情的报道，关注自己曾搭乘过的航班，车次等；如有发热等病症时，要及时主动去医院，配合医生接受检查治疗……
尽管面对这场疾病的来势凶猛，我们所掌握的这些已知因素还是少之又少，但，不能否认，我们的初浅认识，就是一个良好的开始，就是一个征服疾病，征服病毒了

急...！ 请求数学大神们帮我讲讲好吗？

首先根据正方形的面积为12平，可以得到正方形的边长为2根号3，即圆的半径为2根号3，然后圆的面积为12π，空白处的面积为9π，正方形的面积减去四分之一的元的面积为正方形中空白的面积，为12-3π，所以最后用9π-（12-3π），得6π-12

　I love traveling. Traveling not only broadens my horizons but also opens my eyes to the world. What's more, it refreshes me. You can go to Disneyland and experience what it's like to be “a child again!” You can visit one of the “seven wonders of the world,” such as the Grand Canyon and feel the magnificence of nature! You can taste the “magicial” ice water on a glacier, which can help you bee more beautiful and make you live longer. Just fet all trifles and burdens that you have in your mind. Experience is a type of living knowledge. You'll be sure to experience many new things when traveling. You don't even need a tour guide if you long for more freedom. Just don't fet to bring your backpack!

Have you ever imagined a world without trees? Try it, and you will see the whole world dry up and look like a broken tortoise shell. At night, the temperature would drop sharply. Living creatures could not run away and it would be as if they lived in hell.
There are some effective steps we can take now to protect trees. First, strict laws must be enforced. Second, the government should offer subsidies to people who plant trees.
Most important of all, every citizen must develop an awareness of the importance of trees and remember: no trees means no living things.

关于快速提高体育的方法，十万火急

实心球是可以提高的，建议向满分的同学或者老师请教一下，只要掌握正确的方法满分很简单，这是经验之谈，我原本只能扔6.4米左右，找到了方法之后在7.1米左右。立定跳远要有有利的助跳，不要练得太过，反而会拉伤韧带，最后短绳，基本没有什么问题，注意体能训练，一分钟有体力坚持到底就行了
