考查数词。句意：一年有24个节气。谷雨通常在一年中的四月开始。空格前有定冠词the,与可数名词单数month，要用序数词。根据

Grain Rain often starts in Apirl，可知四月份是一年之中的第四个月，要用序数词fourth。故选B项。

to be hosted

hosting

考查非谓语动词。句意：下星期举办的展览将展出当代艺术家的作品。根据句意及分析句子结构可知，此处表示将来发生的事情，应使用不定式作定语，host 与 exhibition 之间是逻辑动宾关系，应使用不定式的被动式。故选C项。

a; the

the; /

/; the

/; /

考查冠词。--你搬到新办公室了吗？--没有，大楼正在建设中。new office 谈话的双方都知道，所以是特指，需要用定冠词the,第二句under construction 指“正在建设中”，是固定搭配。故选B项。

Only then_______ how much damage had been caused.

she realized

she had realized

had she realized

did she realize

“only＋状语”位于句首，整个句子用不完全倒装．此外，由then可确定用过去时态．

I have no one        me. for I am a new comer here.

help

helping

to help

to have helped

考查非谓语动词的用法。句意：我没让人帮我，因为我是新来的。根据句意可知句子空格处非谓语动词作定语，用了have sb /sth to do的结构,意为“让某人做某事”。故选C项。

The question of           English will keeping on changing in the future is easy         .

if; to answer

whether; to be answered

if; to be answered

whether; to answer

考查宾语从句和非谓语动词。句意：英语将来是否会继续变化这个问题很容易回答。第一空为宾语从句，从句中不缺少成分，表示“是否”，应用whether，if 引导的宾语从句不能充当介词的宾语，故排除A和C；第二空，这是be +性质形容词+不定式结构，这种结构中形容词说明不定式的特性，句子的主语是不定式的逻辑宾语。故选D项。

---What is your first impression          our English teacher?

---He is patient but he is strict         us.

with; in 

to; with

of; with

of; at

考查固定短语。句意：---你对我们英语老师的第一印象是什么？---他很有耐心，但对我们很严厉。两句话中介词的宾语都是人，第一句要用impression of sb表示“对某人的印象”；第二句中则要“be strict with”表示对（某人）严格。故选C项。
