The owner of a restaurant must know how to make food. They also need to know how to make money. It's something they get from science learning. Red is a color that makes people hungry. Red also makes customers eat faster.
Therefore, many fast food restaurants have red furniture or walls. Warm colors like pink and light blue make people relax, so they spend more time eating. Warm lighting makes people look better, but it makes food look bad.
Loud music may be good at the beginning, but soon it will make people want to leave. Many restaurants, especially fast food restaurants, use this knowledge to make customers eat faster.
They only sit for about 20 minutes before the customer leaves. Because customers won't stay long, small restaurants can receive more customers every day.
在顾客离开之前他们只会坐大概20分钟。因为顾客不会待很久,小餐馆每天就可以接待更多的顾客。
这部分内容主要考察的一般现在时的知识点:
描述主语的状态、性质、特征、能力等,目的是为了“描述现阶段的动作或者状态。e.g. I don't want so much.我不想要太多。Wang An writes good English but doesn't speak well.王安英语写得很好但是说得不好,比较:Now I put the sugar in the cup.现在我把一些糖放进杯子里面。I am doing my homework now.现在我正在写我的作业。
第一句用一般现在时,用于操作演示或指导说明的示范性动作,表示言行的瞬间动作。再如:Now watch me,I switch on the current and stand back. 第二句中的now是进行时的标志,表示正在进行的动作的客观状况,所以后句用现在进行时。
