篇1：how 引导名词性从句的用法探讨
what与how用法之比较似乎是很简单的一个问题，但宜昌市届第二次调研考试的一道完形填空题却引起了极大争议。现摘录如下：
You must have heard these words like how happy it is to be a child. But would you honestly change places with a child? Think of the years at school: the years spent living in frequent fear of examinations and school activities. Every thought you think is controlled by some adults. Think of the times you had to go to bed early, you had to eat hateful thing that was supposed to be good for you. Remember _______ “gentle” pressure was given to you with words like “If you don't do as I say, I will...” I'm sure you will never forget!
A. what B. why C. that D. how
参考答案为D。对于此空有着如下一些观点：
观点1：应选A。Remember后的宾语从句是一感叹句，而感叹词强调修饰的是名词pressure，故应选用what。
观点2： 应选D。也认为Remember后的宾语从句是一感叹句，而感叹词所强调修饰的名词pressure前有一形容词gentle，故应选用how。
观点3： 应选C。因为what与how引导的感叹句不可用作宾语从句，故A与D均不对。
观点4： 应选D。认为how “gentle”在句中作状语。
笔者认为此题单纯从语法结构上讲，四个选项均对。但在上述特定语境下应选D, how为佳。此时的how引导的并非感叹句，而是一句意思为“……的情形”、“……的情景”、“……的经历”或“怎样、怎么”的连词引导宾语从句，相当于the fact / situation / times / way that。A项what干扰性很大，但由于gentle用了引号且起否定作用，故而不宜构成What “gentle” pressure ... 的感叹句。需注意的是，how与名词连用构成感叹句一般只能是两种形式：how + many / much + 名词；how + 形容词 + a / an + 名词。
由此看来，对how引导名词性从句用法有待进一步探讨。在此谈谈己见。
how引导名词性从句有如下几种情况：
1. 表方式、方法，相当于the way in which。可译作“怎样、怎么”。例如：
I didn't know how he came here.
2. 表程度上的感叹，可译作“多么……、真……、这么……”等。例如：
He said how beautiful those flowers were.
He said how he regretted the hours wasted in the woods and fields.
He was surprised at how much water I had drunk.
3. 表对程度、数量、情况的疑问。例如：
She wondered how he loved her.
I don't know how many students there are in our school.
I have no idea how my mother is now.
I want to know how he is getting on with his studies.
4. 仅用作连词引导间接陈述句，本身无意义。例如：
He told me how (= that) he had read about it in the newspaper.
5. 用作连词，相当于the fact / situation / times... that, 可译作“……的样子”、“……的情形”、“……的情景” 、“……的经历”等。例如：
I still remember how they laughed.
I still remember how I left my hometown for the first time.
I won't forget how we lived together.
I won't forget how I lived in my childhood.

篇2：英语语法名词性从句用法
一、概说
名词性从句，即指性质相当于名词的从句，它包括主语从句、宾语从句、表语从句和同位语从句。从高考的考查的实际情况来看，名词性从句考得最多的是宾语从句，其次是主语从句，再次是表语从句，而同位语从句则很少考查。
二、名词性从句的一般引导词
1. 连接词 that 只起连接作用，没有任何意思，也不充当句子成分，在宾语从句中可省略，但引导其他名词性从句时通常不省略。如：
I hope (that) you enjoy your holiday. 希望你假期过得好。
That he likes you is very obvious. 很显然他喜欢你。
2. 连接词 whether 也不充当句子成分，但有自己的意思，表示“是否”;引导宾语从句时，可换成 if，但引导其他名词性从句时不能换成 if。
He asked whether [if] I would show him the way. 他问我是否可以给他带路。
Whether it will do us harm remains to be seen. 是否对我们有害还要看一看。(引导主语从句，不能用 if 代替 whether)
3. 连接代词 who(m), whose, which, what 等，均有各自的意义，在从句中作主语、宾语、定语等。如：
That’s why she wanted to leave. 这就是她想离开的原因。
When we arrive doesn't matter. 什么时候到没有关系。
Tell me which one you like best. 告诉我你最喜欢哪一个。
4. 连接副词 when, where, why, how 等，也各自有自己的意义，在从句中作状语。如：
The question is how we should carry out the plan. 问题是怎样执行这个计划。
When she’ll be back depends much on the weather. 她什么时候回来在很大程度上要看天气。
Why he did it will remain a puzzle forever. 他为什么这样做将永远是一个谜。
三、名词性从句的语序和时态问题
名词性从句的词序与陈述句语序相同，尤其注意那些由连接代词who(m), whose, which, what 和连接副词 when, where, why 等引导的名词性从句，不要受它们在特殊疑问句中用法的影响而误用疑问句词序。如：
Why was she crying? 她为什么在哭?
I don’t know why he was crying. 我不知道她为什么哭。
名词性从句的时态问题
1. 当主句的谓语动词是过去式时，宾语从句若不是一个客观事实或真理，其谓语动词也必须用某种过去时态。如：
She said that she didn't want to know. 她说她不想知道。
I asked her whether she would agree. 我问她是否会同意。
2. when, if 这两个词既可引导名词性从句，也可引导状语从句。当它们引导名词性从句且表示将来意义时，要直接使用将来时态;但当它们引导状语从句且表示将来意义时，则必须用一般现在时表示将来意义。如：
I don’t know when he will come, but when he comes, I’ll call you. 我不知道他什么时候，但当他来的时候，我会打电话给你。
句中第一个when 引导的是宾语从句，故用将来时态表示将来意义;第二个when 引导的是时间状语从句，故用一般现在时表示将来意义。
