英语中判断是否强调句的根本标准是:采用删除法。即:去掉It
is
/
was
及连接词部分,如果整个句子结构和意义不受影响,那么这个句子就是强调句。如:Was
it
during
the
Second
World
War
that
he
died?(98年高考题)分析:去掉被强调部分during
the
Second
World
War
后,句子结构和意思完整:he
died
这道题主要考查强调句句型和语序变换。如果想不明白可以先写成最简单句式,就是when could we complete the experiment?变成强调句就是When it was that we could complete the experiment.回答的这句话是宾语从句,这个句子在整句话中做宾语成分。宾语从句中,从句若是疑问句,用陈述语序,就是when it was that we could complete the experiment。
另外,题中回答的那句话末尾应用句号,不应是问号
