Question 21 is based on the passage you have just heard.

        Color is now spreading through our homes, up staircases, across wood frames and ceilings, filling in neutral spaces. According to one interior designer, (19) [when people return home, they want to see colors that cheer them up and give them a hug.] Pure white walls simply don’t do that. They don’t look after you. Another interior designer commented that certain combinations can key into something on a deeper level, transporting you to a different moment in time. That’s the power of color. If you’re thinking to try color on some of your neutral walls, the advice is refreshingly simple: choose a color you actually like. (20) [Don’t go for a color because it’s in fashion or you’ve seen it in a magazine.] If you’re wary of full color, test your tolerance with smaller spaces, such as the inside of a cupboard or a bright window frame. If it gives you joy every time you open the cupboard, you can start to take it further. (21) [One can also paint the wooden framework the same color as the walls, helping the rooms look bigger.] In the kitchen, painting the overhead cupboards and walls in the same color can make it feel more spacious, while painting the kitchen counters a bold color can make everything feel more open and lighter. Additionally, a painted ceiling is a magical thing without being too obvious, and can affect how the space feels as well.

21. What can one do to make a room look bigger? （怎样才能让房间看起来更大？）

解析：D。录音后半部分提到，可以将木质框架涂成与墙壁相同的颜色，来让房间看起来更大。D项是对录音中paint the wooden framework the same color as the walls的同义替换，故为正确答案。

错项排除：录音中没有说要把大部分橱柜装在墙上，故A项排除。B项中的landscape paintings在录音中无依据，故排除。录音中只说粉刷天花板会影响空间感，并没有提到要刷成和所有家具相匹配的颜色，故排除C项。
