六个要紧的比较结构使用方法总结
1. as…as的使用方法特征
其间只能接形容词与副词的原级，不可以用比较级和最高级。有时该结构可受nearly, almost, just, nothing like, exactly, not quite, half, one-ten, twice, three times, 30 per cent等的修饰，注意这类修饰语需要置于第一个as之前，而不可以置于其后。如：
The dining-room is twice as big as the kitchen. 餐厅是厨房的两倍大。
At best we can do only half as much as last year. 大家最多能完成去年工作量的一半。
注：该结构中的形容词有时还可修饰另一名词，但这个名词应带有不定冠词。比较：
She is as good a cook as her mother.= She is a cook as good as her mother. 她和她母亲一样是位好厨师。
2. more and more的使用方法特征
其意为“愈加……”，其后可接修饰名词，也可修饰形容词、副词、动词、介词短语等。如：
More and more people are concerning themselves with environmental problems. 愈加多的人关心环境问题。
The little girl is growing to be more and more like her mother. 这个小女孩长得愈加像她母亲了。
As time went on, he found it more and more difficult to support his family. 他日渐发觉要养活一家人是愈加难了。
3. more or less 的使用方法特征
基本意思是“多少”、“在一定量上”、“大体上”、“大约”等。如：
The job is more or less finished. 工作大体上完成了。
His condition has more or less improved. 他的状况多少有的改进。
The repairs will cosplayt $50,more or less. 维修费大约要50USD。
注：在否定句中可表示“一点也不”。如：
I didn't understand it, more or less. 我一点也不懂。
4. more than 与less than 的使用方法比较
more than 的基本义是“多于”，但依据不同状况可以有较灵活的翻译，如表“多于”、“比……多”、“不仅仅是”、“不止是”、“很”等。如：
He’s lived here for more than 30 years. 他在这已住了30多年了。
Two eyes can see more than one. 两只双眼比一只双眼看得真。
He is more than a father to her. 他待她胜过爸爸。
They were more than glad to help. 他们很乐于帮忙。
less than 的基本意思是“少于”、“比……少”。如：
I won’t take less than $5000 for my car. 我的汽车低于5000USD不卖。
The actual cosplayt of repairs was a lot less than we had expected. 实质的维修成本比大家预期的要低得多。
5. more …than 与 less…than 的使用方法比较
从本义上看，前者表示“比……多”，后者表示“比……少”或“不如……”。
He has more money than me. 他的钱比我多。
He is said to pay less income tax than he should. 据了解他所得税交得不够。
另外，两者均可用于引申义，表示“与其……不如……”，但两个比较的对象的地方不同。如：
He is less a teacher than an expert.= He is more an expert than a teacher. 与其说他是老师，不如说他是专家。
6. 关于“no+比较级+than”结构
这种结构一般不是表示一般意义的否定，而是表示对待比较的两个对象同时进行否定，一般可理解为“与……一样不”。如：
You are no more careful than he is. 你和他一样不仔细。
A half truth is often no better than a lie. 半真半假的话常常跟谎话一样糟。
比较并领会以下结构：
no better than = as bad as 与…一样不好
no faster than = as slow as 与…一样不快
no earlier than= as late as 与……一样不早
注：同学们要擅长依据以上使用方法推知其他一些类似结构的意思，如 no more than的意思是“与……一样不多”，强调少，一般可译为“只有”；no less than 的意思是“与……一样不少”，强调多，一般可译为“多达”、“有……之多”。
