1 剑桥语法把引导状语从句的连词一律分析为介词。

2 剑桥语法的比较结构所涵盖的范围远大于一般传统语法书。比如 You are like Tom. 在该书属于比较结构。

3 如果A和B二者之间进行比较，B被称为the secondary term. 这个secondary term就是比较补足语comparative complement。比较补足语在形式上有二种，一种带有介词称为expanded comparative complement，一种没有介词，称为bare comparative complement。例如：You are taller than Tom. taller是比较管控项，它要求expanded comparative complement，即than Tom。You are like Tom. like是管控项，它要求bare comparative complement，即Tom。在下面二个句子中，管控项用黑体表示，比较补足语用斜体表示：

It wasn’t as expensive as she had expected. （expanded）

ii It was reasonably cheap, as she had expected. （bare）

4 关于scalar和non-scalar comparison，你可参读原文：

Scalar vs non-scalar

Scalar comparisons are concerned with relative position on some scale, such as that

denoted by old in [1]; old is a gradable adjective and scalar comparison is one type of

grading, potentially more complex than grading by means of such degree adverbs as

very, quite, rather, etc., but of the same general kind.

Non-scalar comparisons, by contrast, are concerned not with grading but with such

issues as identity and likeness. Bus, for example, is not gradable, and the non-scalar

comparisons in [1] compare the two buses (the one I took and the one I had taken last

time) for identity.

Scalar comparison can be regarded as the more central type: inflectionally marked

comparatives are scalar and, within the inequality category, comparative clauses are rare

in the non-scalar constructions.
