句型梳理
1. That football is such a simple game to play is perhaps the basis of its popularity.足球是一项如此简单的运动，这或许就是它得以流行起来的原因。
考点提炼
that 引导的主语从句
（1）that在主语从句中不充当成分，也没有含义，但通常不能省略。
That our team had won first prize made us very happy.我们队获得了第一名，这使我们很高兴。
（2）that从句作主语时，为避免头重脚轻，保持句子平衡，常用it作形式主语，而将主语从句后置。常用it作形式主语代替that从句的句型有以下几种：
①It+be +形容词(obvious, true, wonderful, likely, possible, certain, ete.)+ that
从句.
②It +be+名词(词组)(no wonder, the case, a pity, a good thing, no surprise, a fact, etc.)+that 从句.
③It +be +过去分词(said, believed, reported, thought, expected, decided, etc.)+that 从句.
It is certain that she will do very well in the exam.她一定会考得很好。
It is no wonder that he failed the exam because he didn't study hard.他考试不及格并不奇怪，因为他学习不用功。
It is reported that no passengers were injured in the accident.据报道,这起事故中没有乘客受伤。
2. You do not have to be a fan to recognise the skill of professional players - how they use their bodies to pass, score and defend can be amazing to see - or to feel the excitement of a game ending with a surprising twist.你(即便)不是球迷，也会赞赏职业球员的球技——他们利用自己的身体传球、得分和防守的绝技让人叹为观止——或者对一场结局有意外转折的比赛感到激动不已。
考点提炼
连接副词引导的主语从句
连接副词when，where，how，why引导主语从句时，在句中既是连接词，又作状语。where在主语从句中作地点状语；when作时间状语；why作原因状语；how作方式状语。在含有连接副词引导的主语从句的复合句中，也常用it作形式主语，代替连接副词引导的主语从句。使用时的注意事项：
（1）从句的语序：在任何情况下，主语从句都用陈述语序；
（2）主谓一致：从句作主语时，主句的谓语动词一般用单数形式。
How life began on earth is one of the biggest mysteries to scientists.对科学家们来说,生命在地球上是如何开始的是最大的奥秘之一。
Where she comes has not been found yet.还没有查清楚她来自哪里。
