1．______ big fire broke out in my neighbor’s house last night，and it took the firefighters about an hour to put out ______ fire.
A．The；a B．A；the
C．The；the D．A；a
解析：考查冠词。第一个空泛指“一场火灾”；而第二个空是特指上文已提及的火灾，所以答案为B项。句意：昨夜我的邻居家里发生了一场火灾，消防员花了大概一个小时才将它扑灭。
答案：B
2．Ashley，______such cases，is sure instantly to come up with a brilliant idea.
A．experiencing B．having experienced
C．to experience D．experienced
解析：考查非谓语动词作状语的用法。由下文的“一定能想出一个出色的办法”可以看出，那个年轻人一定经历过类似的情况。所以要用分词的完成式，强调动作的结果。
答案：B
3．I wonder ______ of you is ______ such an accident.
A．who；to be blamed on B．whom；blaming to
C．which；to blame for D．who；to be blamed for
解析：表示给定范围内的人，问“谁”时用which；be to blame for“因……而受到责备”。

A．being admitted B．to being admitted
C．to be admitted D．to have been admitted
解析：考查sb.is said to do结构。动词admit发生在主句的谓语动词之前，因此D 项符合。
答案：D
5．—I’m sorry to have interrupted you.Please go on.

A．were saying B．had said
C．said D．had been saying
6．I think he must have a dictionary you need，______ he?
A．mustn’t B．doesn’t
C．don’t D．hasn’t
解析：考查反意疑问句的构成。情态动词表示推测时，其后的反义疑问句没有表示过去的时间状语时，由动词决定，动词have是行为动词，由主语he可知用doesn’t。
答案：B
7．One o f the requirements for a fire is that the material ______ to its burning temperature.
A．is heated B．will be heated
C．be heated D．could be heated
解析：考查虚拟语气。that引导的从句作requirements的表语从句，因此要用虚拟语气“(s hould)＋动词原形”，should可以省略。
答案：C
8．We’ll continue to learn by ourselves when we have graduated.We must ______ learn how to study in the university now.

答案：C

C．to seat D．seat
解析：考查非谓语动词。句意：Mary的尖叫声把坐在她周围的女孩们吓坏了。由句意可知“______around her”做girls的定语，动词seat常用的结构有be seated和seat oneself表示“就坐”，这里seated表示坐着的状态，相当于sitting，seat表示“坐着”时，如果用seating作补语、定语或状语，其后面需要跟宾语。
答案：A
