Starter Unit 2 Keep Tidy! 拓展阅读专项 主题：自我管理 Colours have weight 读前预热 你觉得颜色有重量吗？你能猜到有多重吗？让我们看看文章是怎么说的吧。 语篇品读 There are many colours in nature. But do you know if a colour has weight? I think you’ll say “no”. But I am afraid you are wrong. If you don’t believe, you may do a small experiment. First, put two objects with the same weight into two boxes. Then cover the box. Third, wrap one box with a red piece of paper, the other with a white piece of paper. OK. Now hold the boxes with your hand one by one. It is certain that you will think the red one is a little heavier. Why do you think so? A scientist found that different colours have different weight in a man’s mind. So he did many tests and at last he got the result. That is to say, every colour has its own weight in our mind and their order is the same. The heaviest colour is red, then blue, green, orange, yellow and white. The scientist told us that colours also have smell. Can you smell the colour? Of course not. Then why did the scientist say so? That is because every colour stands for a kind of light with a certain wave length. It reaches our brain through sense organs (器官). According to this discovery, scientists say that people accept the colours they like, and refuse the colours they hate. So your body and mind will be healthy by using the colours you like. Or you’ll be nervous or even get ill. For example, if you stay in a room with red windows, wallpapers and furniture for two hours, you’ll feel you have been there for four hours. But if the room is blue, you’ll feel you have been there for only an hour. Another example, if a person walks out of a red room and into a blue room, his temperature will fall. That means our body temperature will change with different colours. 自然界有很多种颜色。但是你知道颜色是否有重量吗？我想你会说“不”的。但恐怕你错了。如果你不相信，你可以做一个小实验。 首先，将两个重量相同的物体放入两个盒子中。然后盖上盒子。第三，用一张红纸包一个盒子，另一个用一张白纸包起来。好的。现在用你的手一个接一个地拿着盒子。肯定你会觉得红色的有点重。 你为什么这么认为？一位科学家发现，不同的颜色在人的心目中有着不同的分量。所以他做了很多测试，最后他得到了结果。也就是说，每种颜色在我们心中都有自己的分量，它们的顺序是一样的。最重的颜色是红色，然后是蓝色、绿色、橙色、黄色和白色。科学家告诉我们，颜色也有气味。你能闻到颜色吗？当然不能。那这位科学家为什么这么说呢？那是因为每种颜色都代表一种具有一定波长的光。它通过感觉器官到达我们的大脑。 根据这一发现，科学家说人们接受他们喜欢的颜色，拒绝他们讨厌的颜色。因此，通过使用您喜欢的颜色，您的身心将变得健康。否则你会紧张甚至生病。例如，如果你在一个有红色窗户、墙纸和家具的房间里呆了两个小时，你会觉得你已经在那里呆了四个小时。但如果房间是蓝色的，你会觉得你只在那里呆了一个小时。再比如，如果一个人走出一个红色的房间，走进一个蓝色的房间，他的体温就会下降。这意味着我们的体温会随着不同的颜色而变化。 词汇积累 experiment [ɪkˈsperɪmənt] n.实验 object[ˈɒbdʒɪkt] n. 物体，实物 wrap[ræp] v. 包，裹 one by one一个接一个 certain [ˈsɜːt(ə)n ] adj.必然的，确定的 stand for 代表 a kind of一种，某种；有一点 discovery [dɪˈskʌv(ə)ri] n. 发现 wallpaper[ˈwɔːlpeɪpə(r)] n.壁纸，墙纸 temperature[ˈtemprətʃə(r)] n.温度；体温 典句分析 1. Third, wrap one box with a red piece of paper, the other with a white piece of paper. 本句是动词原形开头的祈使句，句中one…the other…“一个……另一个……”连接两个并列部分。 2. It is certain that you will think the red one is a little heavier. 本句中it为形式主语，真正的主语是that引导的从句。“It is certain that…”是固定句型，意为“可以确定地是……”。 3. A scientist found that different colours have different weight in a man’s mind. 本句中含有that引导的宾语从句。“in one’s mind”意为“在……的心目中，照……的看法”。 4. According to this discovery, scientists say that people accept the colours they like, and refuse the colours they hate. 本句中含有that引导的宾语从句。从句中“accept the colours they like, and refuse the colours they hate”是and连接的并列复合句，colours后省略了关系词that，“they like”和“they hate”是作定语修饰名词colours。 5. For example, if you stay in a room with red windows, wallpapers and furniture for two hours, you’ll feel you have been there for four hours. 本句中含有if引导的条件状语从句。条件状语从句遵循“主将从现”原则，从句一般使用“一般现在时”，主句使用“一般将来时”。主句“you’ll feel you have been there for four hours”中feel后是省略了引导词that的宾语从句。for后跟时间段,表示“持续多长时间”，常与完成时连用。 读后探究 I.Fill in the mind map according to the passage.
