3.when a pencil is put in a glass of water,it looks as if it________.
a.breaks b.has broken c.were broken d.had been broken
命題意圖：此題考查虛擬語氣用于以as if(as though)引導的表語從句或狀語從句。此題屬四星級題目。
知識依托：如果從句與現在事實相反，謂語動詞用一般過去時；表示與過去事實相反，謂語動詞用“had+過去分詞”；表示與將來事實相反，謂語動詞用“would (might,could)+動詞原形。”
li ming speaks english as if he were an englishman.(與現在事實相反）
it looks as if it might rain.(與將來事實相反）
it seems as if tom had travelled a lot in china before.(與過去事實相反）
錯解分析：本句意思是：當把鉛筆放在一杯水里的時候，它看起來就跟斷了似的。（其實沒斷）與現在事實相反。故選c項。
解題方法與技巧：看when a pencil is put in…中謂語時態。
答案:c
●錦囊妙計
做好虛擬語氣，除了掌握基本的結構外，還要注意句子所表達的意義與現在過去，還是將來事實相反，看清時間狀語，另外還要注意在其他結構中虛擬語氣的運用。
1.在主語從句中謂語動詞的虛擬語氣結構為：“should+動詞原形”表示驚奇，不相信，惋惜等。
例：it is advisable/important/natural/necessary that sb.(should)do
2.在it is time/high time that sb.should do sth.
或it is time that sb.did sth
3.would rather sb.+過去時，指現在或將來。
例：i’d rather father were here now.
i’d rather they came here tomorrow.
4.but for…without短語譯為“要不是……”，句子謂語也常用虛擬。
