That means a Noun Clause serves as Subject in the sentence. The words which are used in this Noun Clause are: that, whether, who, what, which, when, where, how, why, etc.Step 3 Learning the grammar What part does the underlined part serve as in each sentence? A tree has fallen across the road. You are a student. To find your way can be a problem. Smoking is bad for you. “How do you do?” is a greeting. What she said is not yet known. That we shall be late is certain. It is certain that we shall be late. We can see from these sentences that a sentence serves as subject, so we call it Subject Clause.Step 4 Practice主语从句（Noun Clauses as the Subject） 定义： 用作主语的从句叫主语从句，它是名词性从句之一。引导主语从句的连接词有：连词that, whether；连接代词who, what和which；连接副词when, where, how和why。 Step 5 ConsolidationTranslation: 1)What the teacher said today was quite right. 老师今天说的话是十分正确的。2)That they are badly in need of help is quite clear. 他们急需帮助，这是十分明显的。3) Whether they will sell the house is not yet decided. 他们是否卖掉这所房子还没有决定。 4) whatever, whoever也可引导主语从句。 Whatever was said here must be kept secret. 这里说的话都应当保密。 Whoever makes mistakes must correct them. 凡犯了错误的人都必须改正。 Step 6 Exceptions1) It is + adj. / n. +从句 It is a pity/shame that. 遗憾的是 It is possible that. 很可能 It is unlikely that. 不可能 2) It +不及物动词+从句 It seems/appears that. 似乎 It happened that. 碰巧 3) It + be +过去
