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 .
- than cane( 甘 蔗 )sugar does B)does cane sugar C)cane sugar D)than cane sugar
-
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”。
-
rays more than infrared(红外线)
-
rays are more infrared than
-
more than infrared rays
-
more infrared rays than
-
- 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 ,
-
the domestic marketer has
-
the domestic marketer does
-
thoe of the domestic marketer
-
that which has the domestic marketer
- 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.
-
more accurate than sundials
-
more accurate sundials
-
sundials more accurately
-
more accurately than sundials
- 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。
