Is _______ three hours _______ the poor boy to come to school on foot?

it; that it takes

there; that it takes

there; when

it; that

考查强调句。强调句的结构为It’s + 强调部分 + that从句。本题强调时间状语three hours。句意：可怜的男孩步行到学校花了3个小时吗？故A正确。

---My mother hardly watches any sports shows.

---_____.

So do mine

So does mine

Neither do mine

Neither does mine

“so＋助动词（情态动词或连系动词）＋另一主语”，此句型是主谓倒装结构，可以表示前面的情况也适用于后者，使用该句型需要注意以几个方面的问题： 1．该句型只能用于肯定句，不能用于否定句：如果前句是否定句，则要用“neither ／nor ＋助动词＋主语”。 2．句型中的主语与上文中的主语是不同的两个主语3．句型中助动词，包括连系动词和情态动词的时态要和上句中谓语动词的时态相一致。根据上文,我母亲几乎从来不看体育节目.——我的（母亲）也是。结合语境可知下文指的是另一个人的母亲，故用名词性物主代词做主语，上文hardly表示否定含义，故下文用否定形式，选D。

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．

It's really           to know that there're only seven bones in giraffes' long necks.

amazingly

amazed

amazing

amazement

考查形容词辨析。句意：知道长颈鹿的长脖子上只有7块骨头，真是令人惊讶。分析句子结构可知，is是系动词，空格处需填形容词作表语。主语是It,指物，表示“令人惊讶的”，应填amazing。故选C项。

--What is happening in that new area?

---New houses          over there.

are built

are building

have built

are being built

考查时态和语态。句意：在那个新区域里发生什么事情了？那儿建起来许多新的大楼。根据第一句时态is happening 可知，时态用现在进行时，故第二句也要用现在进行时，主语 houses与build 建立之间是被动关系，故用现在进行时的被动语态（am/is/are being done），此处为are being built，故选D项。
