试题分析:考查强调句型。强调句型的基本结构为It is/was被强调成分that/who其它成分;其最大的特点就是去掉it is/was…that/who…句子仍然成立。要注意强调句型能强调除谓语动词以为的所有的句子成分。本题中强调的是时间状语in 1990;句意:就是在1990年这种药物在人类的病人身上测试的。故B正确。 点评:能够准确把握句子结构是关键。随着高考考点的不断深入变化,该句型总是以新的面孔出现,或本身发生变化,或与其他句式结构相结合,然而万变不离其宗,总是脱不掉it,be,that/who这一框架结构。结合近几年有关高考题的特点,将其变化形式归纳如下:强调句型的一般疑问句形式。一. 句式特征:Is/ Was it +被强调部分+ that…;二、 结合特殊疑问词构成特殊疑问句形式。句式特征:特殊疑问词+is/was it that…?三、强调句型的反意疑问句形式。句式特征为:It is/was+被强调部分+that…,isn’t / wasn’t it?四、强调句型的感叹句形式。句式特征为:what/ how … it is (that) +主语+谓语! |
