表语从句比较简单，通常就是将从句置于系动词，尤其是be动词（如is或was）后面。请看例句：

1 Most people get married believing a myth—that marriage is a beautiful box full of all the things they have longed for: companionship, sexual fulfillment, intimacy, and friendship. The truth is that marriage, at the start, is an empty box . You must put something in before you can take anything out. There is no love in marriage; love is in people, and people put it into marriage. There is no romance in marriage; people have to infuse it into their marriages. A couple must learn the art and form the habit of giving, loving, serving, praising—keeping the box full. If you take out more than you put in, the box will be empty.

妙语点睛 这里的that从句是放在is后面作表语，即构成表语从句。

精品译文 很多人结婚时都认为婚姻是一个美丽的宝盒，里边有他们一直渴望的一切：亲密的伙伴关系、性生活的满足、两人之间的卿卿我我以及友谊。但事实是，婚姻一开始是一个空盒子，你得先往里面放进一些东西，才能从里面取出东西。婚姻本身是没有爱的，爱在人的心里，因此人们必须往婚姻中注入爱。婚姻本身也没有浪漫，人们必须在自己的婚姻生活中制造浪漫。夫妻双方应该学会爱的艺术，养成这些良好的习惯：彼此付出、相爱、给予、赞美，让婚姻这个美丽的盒子总是满满的。如果我们的索取多于付出，婚姻这个盒子终究会变空。 很喜欢这段关于婚姻的文字，它告诉了我们一个简单的道理：美好的婚姻或爱情是需要我们用心呵护和经营的，这其中少不了理解、宽容、忍耐和付出，还有就是坚守，不要轻言放弃，因为历经磨难和考验的感情，才会格外的醇香、深厚，以至于无法割舍。这时的感情才臻至完美！ 上面的例句中含有that引导的表语从句，下面我们再来看疑问句用作表语从句的例子。比如下面这句：

2 Some women are much too preoccupied by family. Once the marriage begins to disintegrate, they're lost. That's where their unhappiness springs from and that's why most divorced mothers regard themselves as victims.

妙语点睛 这里的where从句和why从句放在is后面作表语，即构成表语从句。

精品译文 一些女性太专注于家庭了。一旦婚姻开始瓦解，她们就会迷失方向。这就是她们不快乐的原因，也是为什么大多数离婚的母亲认为她们是受害者。
