1. (2022八上·义乌月考) 阅读下面短文，从每题所给的A、B、C、D 四个选项中选出最佳选项。

There are many colours in the world. Do you know that a colour has weight*? I'm not joking. If you don't believe it, you may do a small experiment.

First, put two things with the same weight into two boxes. Then cover the boxes. 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 weights 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 weight in our mind. 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 wavelength*. It reaches our brain* through sense* organs*.

According to this, scientists say that people feel good with their favourite colours. Your body and mind will be healthy by using the colours you like. Or, being with the colour you dislike, you'll be anxious or even get ill. For example, if you don't like red but have to 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 which is your favourite colour, you'll feel you have been there for only an hour.
