First, the Internet opens a window into a wider world, making it easy to visit the magnificent scenery, art-galleries, and even the libraries of top universities and broadening/widening people’s horizon. What’s more, the Virtual Revolution provides people with advanced technologies, improving our work efficiently and effectively.
On the contrary, there is a widespread concern over it. Some people are addicted to the virtual reality, refusing to contact friends in real life. On the other hand, the Virtual Revolution brings some technologies like AI, which make it possible to do harm to human beings if operated inappropriately.
Despite its weaknesses, the Virtual Revolution, full of power and vitality, greatly boosts the globalization of technology and economy. Without it, it is difficult to imagine our tomorrow’s world.
三．当堂检测
Nowadays many people are concerned about the problem of what to do with electronic waste such as old televisions，computers，radios，cellular telephones and other electronic equipment．
Electronic trash，or e-waste is piling up faster than ever in American homes and businesses．People do not know what to do with old televisions or computers so they throw them in the trash．
National Solid Waste Management Association （NSWMA）state programs director Chaz Miller says the large amount of electronic waste Americans product is not unexpected．
The US Environmental Protection Agency （EPA）estimates more than 400million consumer electronic items are dumped each year，and there is a push by more states to ban the waste from landfills （垃圾填埋场）and create recycling programs．They can be torn apart and sorted for useable parts．Mike Fannon who runs the plant in Baltimore says，"There are lots of valuable metals that can be recovered and reused instead of just putting them in the landfill，and in certain components there are some materials that should not really be in the landfill．"
Fannon says nearly 20percent of electronic waste is recycled nationwide．Thirteen years ago，it was only about 6percent．Recycling rates continue to rise as more communities have banned electronics from landfills in order to keep e-waste poisons like lead （铅）and mercury （汞）out of garbage dumps．
This year several states like Vermont imposed a ban on electronic waste in landfills．More than 25 other states have also adopted bans on e-waste in landfills．Chaz Miller says more can be done to boost electronic waste recycling．
"We can do much better，"noted Miller．"I think clearly our goal should be to do as well as we do recycling
newspapers．"
1.Read the passage and write a summary with about 30 words.
2.Write an essay about Electronic Waste
1)Analyze the present situation of the world about Electronic Waste
2)Put forward some approaches to solving Electronic trash.
High-Tech’s problem---Electronic Waste
People tend to throw their electronic waste without knowing what to do with e-waste. Facing the situation, NSWMA put forward an idea that recycling is the best way to avoid polluting environment.
Inspired by high-profit, some companies have been bent on producing and marketing new electronic products. Ironically, the high-speed of technological innovation turns last year’s must-have to this year’s junk. According to the report of the UN, approximately 50 million tons of e-waste is produced each year. Worse still, most of the trash ends up in the landfills, polluting environment, because of the heavy metals from e-waste like circuit boards.
It is high time that we should take immediate action to deal with it. On the one hand, developed countries should ban exporting electronic waste and process it themselves. On the other hand, great efforts should be focused on the recycling program to reuse most of the used e-products by educating people.

导学案NO.1 年级：高一科目：化学主备：审核： 课题：过滤与结晶课型：复习课时 : 1 【考纲解读】 过滤和结晶使用的仪器及其应用 【自学与归纳】 分离和提纯的区别： 分离：是通过适当的方法，把混合物中的几种物质分开，每一组分都要保留下来，如原来是固体，最后还是固体 提纯：指保留混合物中的某一主要组分，把其佘杂质通过一定方法都除去 初中阶段我们学习过的物质的分离方法有：、、。 1、 原理：利用物质的差异，将液体和分离开来。 实验用品：、、、、。 注意事项： 过滤操作实验小结：斗架烧杯玻璃棒，滤纸漏斗角一样。过滤之前要静置，三靠两低不要忘。
2、和结晶 原理：利用的方法，使溶液中不断挥发而析出（晶体）的过程。 实验用品：、、、。 操作注意事项： １）蒸发皿中的液体不能超过其容积 的。 ２）蒸发过程中必须用不断搅拌，防止局部温度过高而使。 ３）当出现时，应停止加热用蒸干。 ４）不能把热的蒸发皿直接放在实验台上，应垫上。 结晶：（冷却热饱和溶液法） 结晶（冷却热饱和溶液法）是分离和提纯混合物的一种方法。它适用于物质的混合物，且混合物中一种物质的溶解度受温度影响变化，而另一种物质溶解度受温度影响变化的混合物的分离和提纯。 【交流与展示】粗盐的提纯 1．粗盐中含有泥沙、氯化钙、氯化镁、硫酸盐等杂质，要通过________、________、________进行提纯。以上操作都要用到玻璃棒，它们的作用依次是： (1)________溶解。 (2)引流。 (3)________________________。 2．粗盐中可溶性杂质的去除方法 杂质加入的试剂发生反应的化学方程式硫酸盐如Na2SO4 MgCl2 CaCl2 多余的__________、 适量____________ ____________ 4 1．试剂：____________； 2．步骤
第一讲定语从句 一关键词 定语从句：在复合句中修饰某一名词或代词的从句叫定语从句。一般紧跟在它所修饰的先行词之后。 先行词：定语从句所修饰的词叫先行词。 关系词：关系词用来引导定语从句。关系词有关系代词和关系副词之分。关系代词有that, which, who，whom，whose，as等；关系副词有when，where，why等。 关系词可以1) 代替先行词；2) 引导定语从句；3)在定语从句中担当一个成分。 例如：The car which my uncle had just bought was destroyed in the earthquake.句中，the car 为先行词；which是关系词引导是定语从句which my uncle had just bought，同时代替先行词the car在定语从句中作主语。 1.关系代词引导的定语从句 who指人，在定语从句中作主语。 whom指人，在定语从句中作宾语，常可省略。 which指物，在定语从句中做主语或宾语，做宾语时可省略。 that指人时，相当于who或whom；指物时，相当于which。在定语从句中作主语或宾语，作宾语时可省略。 whose 通常指人，有时也可指物，在定语从句中做定语。 Note: whose指物时，常用of which结构来代替： 关系代词在定语从句中作主语时，谓语动词要和先行词的性、数保持一致。 注意：which和as引导非限制性定语从句时，有时并没有特定的先行词，而是代表前面说的整个情况。这时which和as 被看作单数，译作“这一点”，其后的谓语动形式用单数形式。如：He said he was a Frenchman，which／as was not true. 但须注意，as引导的这种定语从句可置于主句之前，which引导的这种定语从句只置于主句之后。如：As is known to all，China is a socialist country. China is a socialist country, as/which is known to all. 2.关系副词引导的定语从句 when指时间，在定语从句中作时间状语。 where指地点，在定语从句中作地点状语。 why指原因，在定语从句中作原因状语。 注意：关系副词引导的定语从句经常可以用“介词+关系代词”引导的定语从句来表示。 介词+关系代词 1)根据动词选择介词。I don't know the foreigner with whom my teacher shook hands.（或I don't know the foreigner whom my teacher shook hands with.) Note: who和that不能直接位于介词后作宾语；有的短语动词是不能拆开的，常见的这类短语有：look for，look after等。

A．CaO和CaS B．和 C．C60和C70D．HCNO和HOCN 【练一练】请同学们按照分类进行连线： Na2CO3钠盐 Na2SO4钾盐 K2SO4硫酸盐 K2CO3碳酸盐 （2）氧化物的分类：我们可以按照氧化物的组成将氧化物分为；也可以按照氧化物的性质将其分为。 【练一练】判断如下说法是否正确： （1）金属氧化物都是碱性氧化物（）（2）非金属氧化物都是酸性氧化物（）（3）碱性氧化物都是金属氧化物（）（4）酸性氧化物都是非金属氧化物（）2、分散系及其分类： （1）概念：一种（或多种）物质以形式到另一种（或多种）物质中形成的混合物叫做。分散系中的叫分散质，另一种物质叫。我们可以这样理解分散系：。 分散系的分类：根据将分散系分为 （2）胶体：胶体是的分散系。根据分散剂的状态可以将胶体分为三种：（例如：）、（例如：）、（例如：） 【实验】氢氧化铁胶体的制备： 取100mL烧杯，加入40mL蒸馏水，。 实验1 滴加至。 实验2取100mL烧杯，加入40mL硫酸铜溶液 【实验】用激光笔分别照射上述实验1和实验2分别得到的液体，观察实验现象。 操作现象 用激光笔照射实验1得到的氢氧化铁胶体 用激光笔照射实验2得到的硫酸铜溶液 丁达尔效应：。丁达尔效应是一种区别的有效方法。
必修一 Unit1 Anne’s Best Friend Do you want a friend whom you could tell everything to, like your deepest feelings and thoughts? Or are you afraid that your friend would laugh at you, or would not understand what you are goi ng through? Anne Frank wanted the first kind, so she made her diary her best friend. Anne lived in Amsterdam in the Netherlands during World War Ⅱ. Her family was Jewish so nearl y twenty-five months before they were discovered. During that time the only true friend was her diary. She said, ”I don’t want to set down a series of facts in a diary as most people do, but I want this diary itself to be my friend, and I shall call my friend Kitty.” Now read how she felt after being in the hiding place si nce July 1942. Thursday 15th June, 1944 Dear Kitty, I wonder if i t’s because I haven’t been able to be outdoors for so long that I’ve grown so crazy ab out everything to do with nature. I can well remember that there was a time when a deep blue sk y, the song of the birds, moonlight and flowers could never have kept me spellbound. That’s chan ged since I was here. … For example, one evening when it was so warm, I stayed awake on purpose until half past eleven in order to have a good look at the moon by my self. But as the moon gave far too much light, I di dn’t dare open a window. Another time five months ago, I happened to be upstairs at dusk when the window was open. I didn’t go downstairs until the window bad to be shut. The dark, rainy eve ning, the wind, the thundering clouds held me entirely in their power; it was the first time in a ye ar and a half that I’d seen the night face to face… … Sadly …I am only able to look at nature through dirty curtains hanging before very dusty windows . It’s no pleasure looking through these any longer because nature is one thing that really must be experienced. Yours, Anne 第一单元友谊Reading 安妮最好的朋友 你是不是想有一位无话不谈能推心置腹的朋友呢？或者你是不是担心你的朋友会嘲笑你，会不理解你目前的困境呢？安妮·弗兰克想要的是第一种类型的朋友，于是她就把日记当成了她最好的朋友。安妮在第二次世界大战期间住在荷兰的阿姆斯特丹。她一家人都是犹太人，所以他们不得不躲藏起来，否则他们就会被德国纳粹抓去。她和她的家人躲藏了两年之后才被发现。在这段时间里，她唯一的忠实朋友就是她的日记了。她说，“我不愿像大多数人那样在日记中记流水账。我要把这本日记当作我的朋友，我要把我这个朋友称作基蒂”。安妮自从1942年7月起就躲藏在那儿了，现在，来看看她的心情吧。亲爱的基蒂： 我不知道这是不是因为我长久无法出门的缘故，我变得对一切与大自然有关的事物都无比狂热。我记得非常清楚，以前，湛蓝的天空、鸟儿的歌唱、月光和鲜花，从未令我心迷神往过。自从我来到这里，这一切都变了。 ……比方说，有天晚上天气很暖和，我熬到11点半故意不睡觉，为的是独自好好看看月亮。但是因为月光太亮了，我不敢打开窗户。还有一次，就在五个月以前的一个晚上，我碰巧在
