If a tree has fallen or been cut down, you may be able to see rings. The circles look similar to the rings that appear when you throw a rock in a pond. <br>它们实际上是树树干内的自然标记。如果一棵树倒下或被砍倒，您可能可以看到环。圆圈看起来类似于在池塘中扔石头时出现的环。</div> These rings can tell us a lot about the tree they're found in and the tree's environment. The study of these rings is called dendrochronology [ˌdendrəʊkrə'nɒlədʒɪ].年轮学 Scientists use dendrochronology to learn about the age of a tree, the weather during its life, and any natural disasters or pests the tree endured/忍受/. It's pretty cool that a tree can tell us so much information without being able to talk! <br>这些圆环可以告诉我们很多关于它们所在的树以及树的环境的信息。这些轮的研究被称为年轮学。科学家们利用年轮学来了解一棵树的年龄，其一生中的天气以及树木遭受的任何自然灾害或害虫。一棵树可以告诉我们很多信息而又不能说话，这真是太酷了！ How tree rings are developed<br>Tree rings grow under the bark, and the bark is pushed out while the tree is growing. The inner part of a growth ring is formed early in the growing season, when growth is fast and is known as early wood. The outer portion is the late wood, and is denser/密度大/ than early wood. The outer portion is darker than the inner part.the darkest part of the ring shows the end of the growing season. This means you can count each dark ring as one year! Many trees in places with hot summers and cold winters make one growth ring a year.So, But trees in tropical locations that don't have cold winters may not have tree rings because they grow all year long. <br>树木在树皮下生长，树生长时将树皮推出。年轮的内部部分是在生长季节的早期形成的，这时生长迅速，被称为早期木材。外部是晚期木材，比早期木材更致密。外部比内部暗。环的最暗部分表示生长季节的结束。这意味着您可以将每个深色环计为一年！在夏季炎热和冬季寒冷的地方，许多树木每年都会生长一棵年轮。因此，在没有寒冷冬季的热带地区，树木可能不会长年，因为它们一年四季都在生长。 For the entire life of a tree, a year by year record or ring pattern is formed that reveals the climate conditions in which the tree grew. If a tree grows in a dry place, you can tell its age better than when it grows in a wet place. <br>对于一棵树的整个生命，都形成了逐年记录或环形图，这些图或环图揭示了树生长的气候条件。如果一棵树在干燥的地方生长，那么比起在潮湿的地方生长的树，您可以更好地判断其年龄。 Switching in between bad and good conditions can result in several rings forming in one year. Tree ring growth patterns are affected by the climate, weather, rain, temperature, soil pH, plant nutrition, CO2 concentration/浓度/, and sunspots/太阳黑子/.<br>在不良条件和良好条件之间切换可能会导致一年内形成多个环。年轮的生长方式受气候，天气，雨水，温度，土壤pH值，植物营养，CO2浓度和太阳黑子的影响。 Tree growth rings can tell us about the ancient climate and growth rings can be used to tell the age of a tree. Growth rings can also be used to date the wood in old buildings, ships and s for paintings. <br>Some perennial herb [pə'reniəl] [ɜrb] 多年生草本 species form annual growth rings in their roots that basically follow the same principles as growth rings in trees.<br>树木年轮可以告诉我们有关古代气候的信息，树木年轮可以用来告诉树木的年龄。年轮也可以用于在旧建筑物，轮船和画框中为木材定日期。<div>一些多年生草本植物在其根部形成年轮，基本上遵循与树木年轮相同的原理。</div> M:Here is a wood,and there are tree rings on it, can you count how many rings do you see ,and tell me how old is this tree.<br>S:13,it has 13 tree rings.it is 13 years old.<br>M:Can you guess how old is that tree ,that tree is thicker than this.<br>S:I think it is 35 years old.<br>M:Look at this ring ,can you tell me why is has thick part and thin part.How are they developed.<br>S:Maybe the thick part has more sunshine and more water.the thin part has less sunshine and less water.<br>M:Yes,We are live at northern hemisphere,so the thicker part is south facing.<br>M:Can you see there is a marker in the ring,Can you guess what h to this tree.<br>S:It looks like something digging in it.<br>M:What poked into the truck?Maybe a worm had eaten the bark and eaten inside the truck.Or maybe a bird cut bugs.The tree can tell us lots of information,That is very cool.<br>S:Yes it is so cool.<br> 后面还有一个关于画蚂蚁的内容，之前学过昆虫的构造，画起来特别快。<br>M:The ant has three parts. Do you remember?Head,throx,abdomen.Where are the legs?<br>S:Legs are grow on the throx.<br>M:How many legs does an ant have?<br>S:Ant has six legs.<br>M:And ther are somthing grow on the head.<br>S:There are two antennae an the head,finish.<br>M:You drow so fast. <p>最后逛集市，买了一个生态瓶。</p><p><br></p><p>关于森林同学会的介绍</p> 活动1:挑食的松鼠宝宝<div>（我们找到了这种果子，叫南酸枣，剥开外面绿色的果皮，看到里面的种子，找到一个六孔的，志愿者说可能有变异。尝了尝味道，一股清香，一点点酸，像酸的青枣。）<br></div> 活动2:画一只蚂蚁<br>蚂蚁蚂蚁 活动3:区别香樟树<br>香樟树有浓郁的香味 活动4:萤火虫找朋友<br>萤火虫在夏天晚上7-11点左右出现，根据腹部闪烁的频率找到配偶。 活动5:年轮大不同 活动6:看见声音 活动7:神奇的鸟蛋<br>画一只鸟 活动8:寒窗千秋 活动9:自然中的乘法 <br>看到一朵花看似一个颜色，其实有不同的深浅，大自然中的色彩搭配最自然，最好看 活动11:为翠鸟代言.<div>想一句口号<br>“保护翠鸟，因为美丽且稀少，protect birds,because they are rare.”——想起motorway里面的orchid的内容<br></div> 活动12:斗转星移的森林 活动13:字短情长<br>写一首三行诗。<br>“鸟儿拖着长长的尾巴嗖的一下飞过去，<br>阳光洒在树叶上，把树叶照亮了，<br>我很开心” 这样的公益活动真的很好玩，亲近自然，又能学到知识，还能把以前学过的内容实地考证。
