问题补充:
It’s believed 40% of stars, like the sun, may have planets that orbit them.
A. as many as
B. as much as
C. many more
D. much more
答案:
(答案→)A. as many as
B. as much as
C. many more
D. much more
解析:as much as与…差不多;多达…(表示“量”上的比较),修饰不可数名词,故排除 B;as many as多达…(表示“数目”上的比较),修饰可数名词;many more后接一个名词一定是个复数可数名词。much more后接一个名词,这个名词一定是个不可数名词。这两者可指“更多”,故排除C和D。
