在学习“as...as”结构时,有几点需要特别注意:

  1. 理解含义:“as...as”是一个同级比较结构,表示“和……一样”。例如,“He is as tall as me.”(他和我一样高。)
  2. 词性使用:在“as...as”结构中,第一个“as”是副词,用来修饰后面的形容词或副词原级;第二个“as”是连词,用来连接两个相同的成分进行比较。
  3. 否定形式:在否定句中,第一个“as”可以替换为“so”,构成“not as/so...as”结构。例如,“She is not as/so beautiful as her sister.”(她没有她姐姐那么漂亮。)
  4. 数量或程度的比较:当涉及到数量或程度的比较时,可以使用“as much 不可数名词 as”和“as many 可数名词复数 as”的结构。例如,“I have as many books as you.”(我有和你一样多的书。)
  5. 形容词的位置:当“as...as”结构中间接形容词时,有时该形容词还可以修饰另一名词,但这个名词应带有不定冠词,且要注意词序。例如,“I have as good a voice as you.”(我的声音和你一样好。)
  6. 修饰成分的位置:如果有修饰成分,如“twice”、“three times”、“half”、“a quarter”等,应置于第一个“as”之前。例如,“He is twice as old as she.”(他的年龄是她的两倍。)

另外,还需要注意在实际语境中正确运用“as...as”结构,避免与其他相似结构混淆,例如“more...than”等。通过大量的练习和实际运用,可以逐渐掌握并熟练运用这一结构。

最后,建议学习者在掌握基本用法的基础上,多阅读英语文章,注意“as...as”结构在实际语境中的运用,从而加深对这一结构的理解和掌握。
