To do today's homework without teacher's help is difficult的主语为什么是to do today's homework?
【分析】
1、主语是说明动作的执行者是谁或是什么.
2、在英语中,主语通常由名词、代词、数词、动名词、动词不定式、主语从句等充当.
例如:
The teacher told us an interesting story.老师告诉我们一个有趣的故事.(the teacher,名词)
We love our motherland.我们热爱祖国.(we,主格,代词)
Four and five is nine.四加五等于九.(four,数词)
Walking is good exercise.走路是很好的运动.(walking,动名词)
To see is to believe.眼见为实.(to see,动词不定式)
What you need is more practice.你需要的是更多的练习.(what you need,主语从句)
3、在句子中,主语一般放在句首,但在倒装句中放在句尾.
例如:
So do I.(I,主语,句尾)
Neither has he.(he,主语,句尾)
4、当不定式(to do sth) 做主语时,一般可以用 it 做形式主语,句子意思仍然不变,即句型:
It is/was + 名词或形容词+to do sth.
例如:
你在上面提到的句子可以改为:It is difficult to do today's homework without teacher's help.
【结论】
你所提到的句子属于五种基本句子类型中的SVP(主+系+表)句型,因此,该句子的主语肯定是含有动词不定式的短语“to do today's homework”,without teacher's help 是状语,is是连系动词,difficult是表语,is 与difficult 共同构成谓语.
翻译:没有老师的帮助完成今天的作业是困难的.
