as … as 同级比较：as big as、not as big as (A2)

两样东西一样的时候，说 as + 形容词 + as。

as big as：一样大

• This chair is as comfortable as the sofa.
• Lunch here is as good as dinner.
• Not "Lunch here is as good than dinner." — say "Lunch here is as good as dinner.". 两边都要说 as：as good as。
• 试一试: Wei: Is the red pan bigger than the blue one? Maya: No, it's ___ the blue one. They're the same size. 选出 Maya 会说的话。 (as big as / bigger than / not as big as) 答案: as big as — 两个锅一样大，所以红锅和蓝锅一样大：as big as。

not as big as：没有……那么大

not as … as 表示“不如”。This street isn't as busy as Market Street，也就是 Market Street 更热闹。

• This street isn't as busy as Market Street.
• The small room isn't as warm as the big one.
• 试一试: Maya: Is the new store cheaper than Mosh Market? Wei: No. It's ___ Mosh Market. Everything is a dollar more. 选出 Wei 会说的话。 (cheaper than / not as cheap as / as cheap as) 答案: not as cheap as — 新店里每样东西都贵一美元，所以它没有 Mosh Market 便宜：not as cheap as。
