请教新东方补充材料上几道题，非常感谢：）

1. Local residents claim that San Antonio, Texas, has more good Mexican American restaurants than any city does in the US.

A. other cities do    B. does any other city    C. other cities do   D. any city  E. other cities 正确答案是B， 可是不是应该用 do any other cities 的吗，为什么是用单数的？！我觉得C是不是比B好呢（ any是不是可以省略？）谢谢！！

2. Unlike other arachnids, which have their nerve cells evenly distributed along their bodies, the scorpion's nerve cells are clustered in its head like a mammal's.

正确答案是body, the scorpions has a cluster of nerve cells in its head, as a mammal does. 请教为什么是用单数BODY？

3. According to analysts, an alliance between three major personal computer companies and most of the nation's largest local telephone companies would enable customers to receive Internet data over regular telephone lines with speeds much higher than is currently possible.

A. with speeds much higher than is  B. with speeds that are much higher than are  C. at much higher speeds as are

D. at much higher speeds than that   E. at speeds much higher than are   正确答案是E， 请教D为什么不对，卫为什么要把that改成are?

4. TM, who was a jazz pianist and composer, produced a body of work both rooted in the stride-piano tradition of WS and DE, yet in many ways he stood apart from the mainstream jazz repertory.

D. Jazz pianist and composer TM produced a body of work that was rooted   E. Jazz pianist and composer TM produced a body of work rooted both

正确答案选D， 为什么不是E， 谢谢！

5. When drive-ins were at the height of their popularity in the late 1950's, some 4000 existed in the US, but today there are less than one-quarter that many.

A. there are less than one-quarter that many   B. there are fewer than one-quarter as many  C. there are fewer than one-quarter of that amount

D. the number is less than one-quarter the amount  E. it is less than one-quarter of that amount

正确答案选C,请教为什么不是E， few不是只能用来指人吗? 非常感谢！！！

1. B.

San Antonio has more Mexican restaurants than does any other city.

= San Antonio has more Mexican restaurants than any other city has Mexican restaurants.

any other city, singular form 

2. use "body" to refer to a common characteristic shared by arachnid.

4.E选项还原后应该是：at speeds (that are) much higher than (that) are currently possible.

5.如果要加both,应该是直接放在WS之前，直接修饰WS和DE，错误选项把both放得太远。

同问6。新东方老师说数量词之前表示少都用less.而正确选项选的是fewer.我觉得E不对是因为it没有指代对象。但是D为什么不对呢？因为少了of 吗？

数量词之前表示少都用less，不是数量词，是数字

谢谢大家的回答和帮忙：）但是还有一些疑问

1. 这道题如果有any other cities do的选项是不是也正确？想知道是不是复数也可以, 因为比如我们说 Shanghai is bigger than any other cities in China.”就是用复数的。谢谢

3.becky_bj:E选项还原后应该是：at speeds (that are) much higher than (that) are currently possible.

请教为什么不是 at speeds (that are) much higher than (that) is currently possible.为什么是用are, 这个that不是指代前面customers to receive Internet data over regular telephone lines这件事吗？为什么后面是用are不是用is呢？ 谢谢

5. D就是少了of, 但是还是不懂为什么是用few,谢谢！

是指代speeds，所以用are
