It happens that my new neighbor comes from my hometown.=my new neighbor happens to come from my hometown.
我们可以用句型it+be+被强调的名词或短语+that或who引导的从句来强调句子中的主语，宾语或状语。
如：It was last night (not any other time)that I read about the history of English.
如果不强调任何成分，句子可以是：
I read about the history of English last night.
第三单元
一 宾语不足语
1．宾语补足语为宾语提供更多的信息。
如：They called her the Loulan Beauty.
2．宾语补足语通常以下面形式出现：动词+宾语+宾语补足语，宾语补足语通常可以是名词短语或形容词。
如：They made Professor Zhang chairman of the society.
We found the ruins most interesting.
有时侯带to的动词不定式和不带to的动词不定式可以做宾语补足语。
如：They believed him to be honest.
Professor Zhang s speech made us all laugh.
宾语补足语可以时介词短语。
如：She found ourselves in the middle of a desert.
宾语不足语通常和宾语在数上是一致的。
如：She made Joe her assistant.
She made Joe and Sue her assistants.
二 Either… or… 和 Neither… nor…
1．我们用either…or…来表示选择性。
如：（连接主语）either Ann or Jane should have arrived by now.
(连接动词) people either tried to escape or stayed in their houses.
(连接宾语)we could choose to eat either noodles or rice.
(连接状语)they are going to the museum either today or tomorrow.
我们用neither…nor…来连接表示否定的观点。（both…and…的反义词）
如：neither the museum nor the site itself interested her.
They neither told me the location nor showed me the map.
I ate neither the noodles nor the rice.
They went there neither by train nor by air.
三 主谓一致
主谓一致是指在主语后选择正确的单复数形式。以下几点帮助我们决定动词是单数或是复数。
动词应是单数，如果主语是：单数的名词或不可数名词
如：the city was founded in the 8th century BC.
The food they offered on the plane was delicious.
