答案與解析：

1.D　　 在if only引導的句中常使用虛擬語氣。這種虛擬結構與虛擬條件句里謂語形式相同。題意為：要是我聽過那個講座或好。

2.A　　由句中的“Alice is ill today.”可知本小題的空白處應填入表示與現(xiàn)在情況相反的虛擬結構。題意為：瑪麗今天生病了，如果她沒生病的話，她不會缺課的。

3.D　　“Without your help”實際上相當于一個虛擬條件句，在此句中表示與過去相反的虛擬條件句。Without your help= If you hadn’t helped us.題意為：如果沒有你的幫忙的話，我們不會取得這么多的成就。

4.B　　wish后面的賓語從句中謂語動詞要使用虛擬語氣。“…what you did when we were at high school.”暗示在本小題的空白處應填入表示與過去情況相反的虛擬結構。題意為：我們多么愿在中學讀書時能夠做過你曾做過的事情呀。

5.D　　 在ask（要求）后面的賓語從句中，謂語動詞也常用虛擬語氣形式：（should）+ 動詞原形。題意為：他要求給他個機會來解釋他拒絕到那里去的理由。

6.A　　 當動詞insist 的意思是“堅持說”時，其后面的賓語從句中不使用虛擬語氣結構。題意為：彼得堅持說他沒偷過任何東西。

7.B　 本句為對現(xiàn)在情況虛擬，主句為would, should（第一人稱），could等加動詞原形。

8.B　suggest意為“建議”時，后面，的賓語從句要用should+動詞原形，但在本題中suggest意為“說明”，“暗示”，其賓語從句的動詞按正常情況處理，故不選C D; A項時態(tài)不符合題意。

9.C　　 在demand（要求）后面的賓語從句中，謂語動詞也常使用虛擬語氣形式：(should) +動詞原形。題意為：父親要求我們一放學就回家。

10.B　　表示與過去情況相反的虛擬結構。題意為：如果我曾知道他住在哪里的話，我會給他寄封信的。
