1.It's the Korean Peninsula that's getting a lot of attention right now because of something that happened in the Yellow Sea back in March.

it强调句型

在英语中，我们常用It is／was… who/that结构来突出强调句子的某一成分(一般是句子中主语，宾语或状语)。在这个句型中，it没有词汇意义，只是引出被强调的成分。如果被强调的成分是表示人的词，用who或that来连接都可以。如果是其它成分，则一律用that来连接。

E.g. It is my mother who／that cooks every day.

E.g. It was yesterday that Tom passed in the maths exam．

使用本句型的几个注意事项

1)被强调成分是主语，who／that之后的谓语动词应该在人称和数上与原句中的主语保持一致。

   e.g. It is I who am right．

e.g. It is he who is wrong．

e.g. It is the students who are lovely．

2)即使被强调成分是句子中的时间状语，地点状语，原因状语等，也不能用when，where, because，要用 that。

   E.g.  It was after the war was over that Einstein was able to come back to his research work again .

E.g. It was in front of the bank that the old lady was robbed．

E.g. It was because of the heavy rain that he came late．

3)如果被强调的成分有同位语，同位语也应提前。

It was from him，his chemistry teacher，that Paul learned to watch carefully in class．

4)被强调成分是作主语的代词，用主格，是作宾语的代词，用宾格

It was he that helped me yesterday. It was me that he helped yesterday.

5)被强调部分既包括人又包括物，用that不用who

lt was the things and people that they remembered that they were talking about．

2.The results point the finger at North Korea, that a North Korean submarine launched a torpedo that sank the South Korean ship.
