选择题
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
