Answer 1

B

試題分析：句意：別把這花瓶拿得跟它好像是用鋼做的似的。as if“仿佛，好像”其后內容若與事實不符則用虛擬語氣，花瓶不是用鋼做的，因此選擇B。若其后發(fā)生的可能性較大則用陳述語氣。
點評：近幾年的高考多次出現(xiàn)了考查虛擬語氣的試題，需要考生要熟記一些虛擬語氣的各種用法。as if 從句用虛擬語氣的情況是當說話人認為句子所述的是不真實的或極少有可能發(fā)生或存在的情況時。從句虛擬語氣動詞時態(tài)的形式如下：
（1）如果從句表示與現(xiàn)在事實相反，謂語動詞用一般過去時
如： You look as if you didn’t care． 你看上去好像并不在乎。
He talks as if he knew where she was． 他說話的樣子，好像他知道她在哪里似的。
（2）從句表示與過去事實相反，謂語動詞用“had＋過去分詞”。
如： He talks about Rome as if he had been there before． 他說起羅馬來好像他以前去過羅馬似的。
The girl listened as if she had been turned to stone． 那女孩傾聽著，一動也不動，像已經(jīng)變成了石頭似的。
（3）從句表示與將來事實相反，謂語動詞用“would／could／might＋動詞原形”。
如： He opened his mouth as if he would say something． 他張開嘴好像要說什么。
It looks as if it might snow． 看來好像要下雪了。
即學即練：He felt as if he alone ___ what had happened.
A. be responsible to B. should be responsible to
C. be responsible for D. were responsible for
解析：D 句意：他感覺唯獨他一個要承擔事情的責任。
