Question

There are many trees on_______ side of the street, and_______ of the trees is still growing.

A．both; the number	B．either; the number
C．both; a number	D．either; a number

Answer 1

B

試題分析：句意：街道兩邊有許多樹，并且樹的數量仍在增長。Both兩者都，后跟復數名詞；either兩者中的任何一者，后跟單數名詞。The number of…的是數量，作主語時謂語動詞用第三人稱單數式；a number of許多，修飾復數名詞。所以選B。
