阅读下面材料，在空白处填入适当的内容(1个单词)或括号内单词的正确形式。
[2017·广东高考]Mary will never forget the first time she saw him. He suddenly appeared in class one day,
16
(wear) sunglasses. He walked in as if he
17
(buy) the school! And the word quickly got around that he was from New York City.
For some reason he sat beside Mary. Mary felt
18
(please), because there were many empty seats in the room. But she quickly realized that it wasn't her, it was probably the fact that she sat in
19
last row.
20
he thought he could escape attention by sitting at the back, he was wrong. It might have made it a little
21
(hard) for everybody because it meant they had to turn around, but that didn't stop the kids in the class. Of course whenever they turned to look at him, they had to look at Mary,
22
made her feel like a star.
“Do you need those glasses for medical reasons？” the teacher asked. The new boy shook his head. “Then I'd appreciate it if you didn't wear them in class. I like to look at your eyes when I'm speaking to you.” The new boy looked at the teacher
23
a few seconds and all the other students wondered
24
the boy would do. Then he took
25
off, gave a big smile and said, “That's cool.”
Step 1：通读全文，掌握主旨大意。
本文主要讲述的是Mary与新转来的学生在课堂上发生的一些趣事。
Step 2：逐题解答，确定答案。
16．wearing。 根据结构可知，此处考查非谓语动词，判断wear的逻辑主语。
17．had bought。 as if后面跟的虚拟语气，表示与过去事实相反的假设。
18．pleased。felt为系动词，其后跟形容词，注意please的形容词形式。
19．the。考查冠词用法。
20．If。根据句式结构可知，此处考查连词，根据语义来判断此处填表示条件的连词if。
21．harder。考查形容词的用法，a little用来修饰比较级，结合语境可知。
22．which。此处考查定语从句，根据句子可知此处考查非限制性定语从句。which引导定语从句并在从句中作主语。
23.for。根据空格位置可知此处应填介词，结合语义可知答案。
24．what。考查名词性从句用法，根据wonder后跟从句可知，该从句为宾语从句，因此按宾语从句选择连词的方法确定答案。
25．them。根据句子结构可判断考查代词用法，结合语义，判断代替的内容确定答案。
Step 3：代入验证。
需考虑语法结构正确且语义符合逻辑，语法结合语义才能确保万无一失。
