誘思：實例點撥
【例1】 (遼寧模擬) do you have any idea________ is actually going on in the classroom?
a.that b.what c.as d.which
提示:填上what之后，形成一個名詞性從句作idea的同位語。
答案:b
講評:從句子的意思上來判斷用詞。
【例2】(廣東模擬) years ago we didn’t know this,but recent science________ that people who don’t sleep well soon get ill.
a.showed b.will show
c.has shown d.is showing
提示:由于we didn’t know this與“現代科技已經證明睡不好覺的人會生病”相互對比，所以this即指后文的內容，用現在完成時表示對現在的影響。
答案:c
講評:注意recent science表示的是最新的研究成果表明的現實問題。
【例3】 (江蘇模擬) —don’t you think it necessary that he________ to miami but to new york?
—i agree,but the problem is________ he has refused to.
a.will not be sent;that b.not be sent;that
c.should not sent;what d.should not send;what
提示:在“it is necessary that＋從句”句型中，從句謂語動詞用should do的形式，should可以省略，由此可以排除a項；send與him之間構成邏輯上的動賓關系，所以send應該用被動語態的形式，由此可以排除d項；從句意看，“the problem is__________ be refused to”是一個表語從句，意為“問題時他已經拒絕了”，由此可排除c項。
答案:b
講評:本題考查點較多，既考查了虛擬語氣，又考查了表語從句，可以先從一點入手，逐一解決。
