　　(1)______a mobile phone can you ring ______ you want to talk with anywhere.

　　A．Using; whoever

　　B．Only on; whomever

　　C．Only by; whatever

　　D．With; anyone

　　答案：B

　　解析：考查“only＋介词短语”置于句首时，主句要倒装，以及who(m)ever， whatever和anyone的区别。由主句can you...倒装，可排除A、D两项。“用手机”应用on a mobile phone或by mobile phone，故排除C。

　　(2)Only by following this method ______.

　　A．we can study English well

　　B．can we be able to study English well

　　C．can we study English well

　　D．study English well can we

　　答案：C

　　强调句型：It is/was＋被强调成分＋that/who＋其他部分

　　提示：

　　(1)只能强调句中的主语、宾语和状语，不能用该句式强调句子谓语。

　　(2)如果强调两个以上的并列主语，该句式仍用is/was，不用are/were。

　　(3)强调部分为表示“人”的名词时，可用who；其他情况则用that。

　　(4)强调not...until 句型时，要将主句中的not一起强调。即It is/was not until...that...

　　(5)Is/Was it＋被强调成分＋that...？为其一般疑问句形式。

　　(6)特殊疑问词＋is/was＋it＋被强调成分＋that...？为其特殊疑问句形式。

　　(7)强调句的特殊疑问句如果用于宾语从句中，该强调句式要用陈述语序。

　　①It is I that/who am going for a holiday with Mary.是我要跟玛丽一块儿去度假。

　　②When is it that we will have a meeting?我们什么时候开会？
