[一点就通]英语中,我们可以在某些固定句式中使用形容词来提供关于某人或某的相关信息。这类固定句式主要有下面三种: 句式一:It is + adj. + that 从句
此句式用来说明我们对某事的感受。 其中it是形式主语,而放在句尾的that从句 才是真正的主语。例如:
It is dan gerous that you cross the road now现在你穿过马路是很危险的。 句式二:It is + adj. + to do sth
此句式也用来说明我们对某事的感受, 意思是做某事怎么样”。其中it是形式主 语,真正的主语是后面的动词不定式短语。例如:
It ' pleasant to meet old friends here在这儿遇见老朋友真让人高兴。
物
另外,此句式中的形容词也可以是名词 (短语 )。例如:
It ' asgood idea to organize a charity show举行慈善义演是一个好主意。
句式三: It is + adj. + for sb + to do sth 在此句式的意思是 “对某人来说做某事怎么样 ”。其中 for 引出动词不定式的逻辑 主语,指明我们说的是谁。例如: It is important for you to read English every day.对你来说,每天读英语是很重要的。 该句式有时可与句式一互换使用。例如:
It 'nsecessary for us to raise money for Project Hope. =It 'nsecessary that we raise m oney for Project Hope. 我们有必要为希望工程筹资。
Key:
1. It is polite that students often give seats to the elderly on the bus. 2. It is impossible to finish all the homework in an hour. 3. It is dangerous for her to go swimming alone.
4. It is tough to walk a 100-kilometre trail within 48 hours. 5. It is meaningful for Dr Ma to work for ORBIS.
6. It is sad that some children in poor areas cannot go to school.
