1．To understand the grammar of the sentence, you must break it ___ into parts.
A．down B．up C．off D．out
解析：
break off意为“断开；推断；停顿；中断”，break out意为“爆发”，它们不合题意。当作“拆开，拆散（divide sth. into parts）”讲时，break up同break down,如：Sentences can be broke up（= broken down）into clauses （句子可分成从句），但若表示“划分（以便分析或更容易得到）（divide sth. into parts in order to analyze it or make it easier to do）”之意时，只能用break down.
答案：A
2．Though ____ money, his parents managed to send him to university.
A．lacked B．lacking of
C．lacking D．lacked in
解析：
“缺少钱”和句子主语之间构成主动关系，排除A、D；lack用作动词搭配为lack sth.或be lacking in，因此B项搭配错误。
答案：C。
3．— You seem to show interest in cooking.
— What? ____, I’m getting tired of it.
A．On the contrary B．To the contrary
C．On the other hand D．To the other hand
解析：
On the contrary强调否定或反驳对方，而To the contrary意为“反对地，On the other hand意为“另一方面”，逻辑不对。
答案：A
4．The classroom is big enough _______, but we’ll have to move if we have more students.
A．for the moment B．on the moment
C．in a moment D．for a moment
解析：
for the moment意为“目前，现在”，全句意为“教室目前够大的，但是如果再有学生我们就要搬。”in a moment意为“马上，立刻”，for a moment意为“片刻，一会儿。”
答案：A
5．He hesitated for a moment before kicking the ball, otherwise he _____ a goal.
A．had scored B．scored
C．would score D．would have scored
解析：
考查虚拟语气的用法。根据otherwise可知要用虚拟语气。虚拟过去发生的事，主句谓语动词要用would＋have＋过去分词。句意为“踢球前，他犹豫了一会儿，否则他就会进球。”
答案：D
