（前后相比的应该是今年和去年注册参加的人数“the number of”故代替它的应该是单数指示代词“that”，而不能选择B，those是指代participants，不是同类对比，答案为D.

Young readers， more often than not， find the novels of dickens far more exciting than Thackeray's.

3）比较级与倍数词关系及其位置

原级结构中可插入表达倍数的词，表示为“为…。若干倍”，当与有表示倍数比较的词在一起时候等，他们的位置是，倍数词+as…as…，或倍数词+more…than…，但again一般放在原级词之后，即 “as+原级＋again+as”。如：

Smoking is so harmful to personal health that it kills people each year than automobile accidents.

[A] seven more times [B] seven times more

[C] over seven times [D] seven times

（答案为B）

“Do you regret paying five hundred dollars for the painting？”“No， I would gladly have paid for it.”

[A] twice so much [B] twice as much

[C] as much twice [D] so much twice

（答案为B）

4）下列词和短语不用比较级形式却表示比较概念：

[A] superior [B] advantageous [C] super [D] beneficial

（答案为A）

5）“比较级＋and +比较级”或“more and more/less and less +原级”以及“ever， steadily， daily等副词＋比较级”结构表示“越来越……”的意思，与这类结构搭配的常用动词有grow， get ，become等。前面两种情况更多地出现在进行时态中，注意的是这三种情况引导的比较级后面都不需要用than.如：

Things are getting worse and worse.

As I spoke to him he became less and less angry.

Her health was becoming daily worse

The road got ever worse until there was no road at all = the road got worse and worse.

6）比较级前面可以用even， still， yet ，all the （more）等修饰语用以加强语气，表示“更加”的意思。如

Today it is even colder than yesterday

I have yet more exciting news for you
