Question

– Who are playing football in the gym now?
– ________ the students from No. 1 Middle School.

A．They are

B．It is

C．There are

D．That is

Answer 1

B

试题分析：考查强调句型。本题第二句后面省略了who/that are playing football in the gym now.句意：—在体育馆里踢球的是谁啊？—是来自一中的学生在里面踢球。故B正确。
点评：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。在考查的时候，经常会把强调句型和定语从句结合在一起考查，要注意分析句子的成分。
