People are puzzled ________ they read the book.

A.the first time

B.at the first time

C.for the first time

D.at first

答案

答案:A

the first time     第一次,名词词组用作连词,可引导句子;

for the first time 第一次,使用时作时间状语,类似副词性,不可引导句子。

举个两个例句:

This is the first time that I have been to America

I saw the sea for the first time in my life .

本题需要选连词连接两个句子,所以选择A
