简单的说,(1)主语从句即用that,whether,who,what,whatever等 引导的从句
(2)连词位于句首不能省略
(3)主语从句大多数情况下视为第三人称单数,但也有例外,如 例: What we need are good doctors
所以
这幅图片显示的是关于人口的问题可以翻译成:What the picture shows is that the problem about population.
希望对你有帮助~~
在句子中担当主语的从句就叫做主语从句,通常放在主句谓语动词之前或由形式主语it代替,而本身放在句子末尾。
This picture shows the problem of population,
What the picture shows is a problem about population.
