强调句式。
的有关信息介绍如下:嘿嘿 我就猜到是你问的...句型结构:It is/was+强调部分+that+其他部分其中:It is/was与that无实意,去掉后,句子仍然完整例如:It is from the sun that we get light and heat.=we get light and heat from the sun. It was I that /who met your sister in the park last night .(强调部分为主格人称 ,可用who代替that)=I met your sister in the park last night .
