二、“形(副)比较级+than 表示一方比另一方“更加⋯”,连词 than 后可接名词(代名词)、名词短语、也可接句子。

例:

Colleges and universities across the nation have decided to do more than talk about the rise in student cheating.全国大学已决定,关于学生作弊的问题不只是停留在口头上。

Fructose (果糖) is a monosaccharide (单糖) sugar that is much sweeter .

  1. than cane( 甘 蔗 )sugar does B)does cane sugar C)cane sugar D)than cane sugar
  1. 为正确答案,本句为两种事物(糖)进行比较,前面一种比后面一种更甜(sweeter),故应使用“比较级+than”结构。A)不对,因为选项中的代词 does 无所指(与词前动词不一致),不过本句空白处可填入“than cane sugar is”。

    1. rays more than infrared(红外线)

    2. rays are more infrared than

    3. more than infrared rays

    4. more infrared rays than

  1. 为正确答案。本句中的比较级为形容词 more(much 的比较级),被比较的两个事物为“hot objects”和“cold objects”,在所释放(emit) 的红外线(infrared rays)的量上,前者多于后者。其中 more 修饰infrared rays,它们不能被分开,故只有 D)在词序上正确。空白后面为倒装语序,其中的 do 代替动词 emit,本句空白也可用正常语序,即“cold objects do”。

The activities of the international marketing researcher are frequently much broader than ,

  1. the domestic marketer has

  2. the domestic marketer does

  3. thoe of the domestic marketer

  4. that which has the domestic marketer

  1. 为正确答案。比较句中,连词 than 前后,即所比较的成分要一致,应该在同种事物间进行比较。一句所比较的是两种 activities,故 C)正确,代词 those 代替“the activities”。

例:

The development of mechanical timepieces(时计,指钟表)spurred the search for with which to regulate them.

  1. more accurate than sundials

  2. more accurate sundials

  3. sundials more accurately

  4. more accurately than sundials

  1. 为正确答案。本句空白处缺名词短语,作介词 for 的宾语,A)和 D)不符合条件,而且连词 than 前后比较的成分不一致;C)不符合逻辑,因为副词比较级 more accurately 从语义上无法修饰动词 spurred;只有 B) 符合条件,“more accurate sundials”意为“更为精确的日规”,此处无必要说出被比较事物。
