Students who volunteer
学生志愿者
Mario Green and Mary Brown from Riverside High School give up several hours each week to help others.
马里奥和马丽是河边中学的学生，他们每周都会抽出几个小时的时间去帮助别人。
Mario loves animals and wants to be an animal doctor. He volunteers at an animal hospital every Saturday morning. Mario believes it can help him to get his future dream job. “It’s hard work,” he says, “but I want to learn more about how to care for animals. I get such a strong feeling of satisfaction when I see the animals get better and the look of joy on their owners’ faces.”
马里奥非常喜欢动物，他的愿望是长大成为一名兽医。他每周六上午都在一个动物医院做志愿者，他相信这会对他将来当上兽医有所帮助。他说过：“这很难，但是能学到很多照顾动物的知识，当动物们在我的照顾下越来越越好并展露笑颜时，我感到了极大的满足。”
Mary is a book lover. She could read by herself at the age of four. Last year, she decided to try out for a volunteer after-school reading program. She still works there once a week to help kids learn to read. “The kids are sitting in the library, but you can see in their eyes that they’re going on a different journey with each new book. Volunteering here is a dream come true for me. I can do what I love to do and help others at the same time.”
马丽热爱读书，她在四岁时就可以自己看书。去年，她决定在一个课后阅读组织里做志愿者。她每周去组织里一次帮助孩子们学习阅读。她说“孩子们坐在图书馆里，当读到每一本新书时，你都能从他们的眼睛里看到他们经历了一段不同的旅程，在这里帮忙是实现了我的一个愿望，我能做自己所爱的同时帮助别人。”

There
is something in the American character that is suspicious of
reading
as anything more than a tool for advancement. America is
also a nation that
prizes sociability and community, believes that
alone leads to loner, loner
to loser. Any sort of turning away
human contact is suspect.
美国人的个性使得他们怀疑阅读不仅仅是提升自己的工具。美国也是一个崇尚社交和社区意识的民族。他们相信闭锁导致孤独，孤独招致失败。任何自我闭锁的行文都是可疑的。
We
have
a get-out-and-going ethos at the heart of our national character.
The
images of American Presidents that stick are those that portray
them as men
of action: Theodore Roosevelt on safari, John Kennedy
throwing a football
around with his brothers. There may only be
Lincoln to give solace to
the
inveterate reader, a solitary figure sitting by the fire who
believed
that books held the knowledge he so eagerly sought. “My
best friend’s the man
who’ll get me one,” he once said.
在我们的民族性中，有一种“出门走起”的精神。美国总统的形象通常都是哪种行动型男人： 西奥多 罗斯福在非洲狩猎；约翰 肯尼迪与兄弟们玩儿橄榄球。对于那些埋头读书、独坐壁炉畔认为书籍才是他热切搜索的知识的源泉的人来说，只有林肯可能会给他们一点儿安慰，因为这位总统曾经说过：我最好的朋友就是那个给我一个朋友的家伙。

光学设备中，counts/(μW/cm2)代表什么含义？
辐照度：投射在单位面积上的辐通量，单位uW/cm2(微瓦特/平方厘米)光亮度nit：nit = cd/m2光通量：点光源或非点光源在单位时间内所发出的能量,其中可产生视觉者（人能感觉出来的辐射通量）即称为光通量。光通量的单位为流明（简写lm），1流明（lumen或lm）定义为一国际标准烛光的光源在单位立体弧角内所通过的光通量，由于整个球面面积为4πR2，所以一流明光通量等于一烛光所发出光通量的1/4π，或者说球面有4π,因此按照流明的定义可知一个cd的点光源会辐射4π流明，即φ（流明）=4πI（烛光），假定△Ω为很小的立体弧角，在△Ω立体角内光通量△φ，则有△φ=△ΩI

1, only plants the health, not in spite of one's illness insect pest's seed, the seedling or other reproduction material. must be perfect from the technology, the prestige fine Production unit purchases the seed seedling, and guarantees it not in spite of one's illness insect pest. 2, if possible as far as possible plants the disease-resistant variety. compares with other crops, the flowers and plants must fall behind some in the disease-resistant new variety selective breeding, no matter but how, when in the greenhouse has such as the ash mildew and so on chronic plant disease, the choice disease-resistant variety is specially important.
3Carries on the isolation cultivation to external and the newborn introduction's planter material. when plants when seedling from different place and Production unit, isolates the cultivation them with the original planter's crops is very important, isolates in the process. The isolation must carry on until may determine that the new seedling does not have plant disease.
4Maintains the good environmental sanitation frequently. in the greenhouse maintains cleanly, plant disease occurs with the spread opportunity is smaller. This means that around the greenhouse corridor and the greenhouse does not have the phenomenon which the weed multiplies. The plastic water pipe and the nozzle have not placed at will ground or soak in the basin. Withered leaf remnant as well as abandons the flowers take out promptly from the adult plant, trash has not thrown anywhere, but places in the trashcan. Among production in enormous quantities's one kind of flowers and plants crops area, other flowers and plants type cannot insert places, affects the global administration. In carries in specially the potted flower the trough field planting and transfers in trough's production region, before the operation, must carry on disinfection processing, reduces the germ dissemination the opportunity.
5Monitor insect mouth density and as far as possible its pressure to lowest. to cause the harvest cuting flower or the trough health does not have plant disease, the grower must as far as possible press to lowly harmful insect's insect mouth density, the harmful insect not only through takes the food to cause the damage to the adult plant, will disseminate each kind of plant virus. The insect which will cause the quite big losses in the economy will be the flowered thrips, the monitor thrips available yellow and the blue color oriental army worm board. The monitor insect mouth density may know the harmful insect type which and the insect mouth density in the greenhouse exists.
6Through greenhouse environmental condition control reduction plant disease's occurrence. in the greenhouse the humidity is higher, has plant disease's risk to be bigger. This is because under the high-moisture condition, the majority of mushroom poisoning thrive well spread, the greenhouse internal phase to the humidity upper limit is 85%. When the relative humidity is bigger than 85%, even if the use disinfectant, plant disease were still very rambunctious down. The excessively high humidity may through the heating, ventilate and so on methods to descend fall. Must avoid on the adult plant leaf blade the long time adhering to stick cohere the waterdrop. When the use spray irrigation or the nozzle water, should better carry on early morning, with the aim of causing on the adult plant the waterdrop approaches before the evening changes does. Wants pi to exempt waters excessively, will otherwise promote root rot's occurrence, must use the draining water good cultivation matrix. Only if knew that the natural soil does not contain the disease germ, otherwise do not in the soil-free cultivation the matrix and the soil mix use, because the majority of soils include cause the adult plant root-rot germ. If uses bed's form cultivation, must guarantee that underground does not have the insulating layer, cannot the water.
7Avoids the adult plant suffering each kind of bad condition the stimulation or the coercion. the adult plant suffers the coercion is bigger, the infection germ's possibility is also bigger, avoids the adult plant suffering the coercion to mean that the adult plant has the sufficient moisture content supply, in the soil salinity content is at the state of equilibrium, the illumination and the temperature meets the requirements which the adult plant grows, the nutrition balanced causes the adult plant to be at the best growth condition sufficiently. If in the soil the salinity is excessively high, adult plant's root system easy to receive the damage. But is injured the root system is easier to infect the germ to corrupt. Also the similar many questions also will occur.

产生不规则的表面。它们也可以用来钻，内孔，切齿轮，并产生插槽。在铣削中最常用的机器类型的商店随处可见学生是一个垂直的轴旋转头机一。虽然有一些其他类型铣床，该文件将只集中于立式铣床。
阿铣床删除由旋转多齿刀是将工件移动喂食金属。主轴可受够了上下同在头上羽毛饲料杠杆。
在X，Y和Z轴手动床还可以通过饲料。这个片段中的Z轴调整，再y轴，比十。
一旦一轴位于一个理想的位置，将不再是美联储，它应该被锁定在与吉布锁位置。
大部分机器都配备了铣削力的一个或多个轴的饲料。功率比人工饲料饲料是平滑的，因此，可以产生更好的表面光洁度。电力饲料也减少了对长期削减操作员的疲劳。在一些机器，电力饲料是控制向前反向杠杆和速度控制旋钮。
修剪头
建立垂直铣床头可以倾斜的形式从正面和侧面来支持。这使得对机器的多功能性，但这些调整可以漂移。有时，一应检查和调整，使主轴头将正常的表的飞机。安装拨号指标探头朝下。降低主轴，直到接触百分表表然后注册大约三分之一的革命一半。设置拨号指标是对你和边框设置为零。主轴旋转180度的手。如果拨号指标仍然读取零，主轴对齐从前到后。如果不是，调整读取头，直到拨了一半，原来阅读遍历整个过程，直到错误属于可接受的范围。重复与流离失所拨号过程左，右下车头部一侧到另一侧。
