小學英語語法知識點：特殊的虛擬語氣詞should

　　1） It is demanded / necessary / a pity + that…結構中的主語從句的謂語動詞要用should 加動詞原形， should 可省略。

　　句型：

　　（1）It is+suggested+that…+ (should) do

　　（2）It is++important+that…+ (should) do

　　（3）It is+ a pity+that…+ (should) do

　　(1)suggested， ordered， proposed， required，　 demanded， requested， insisted； + (should) do

　　(2)important， necessary， natural， strange

　　a pity，　 a shame，　 no wonder

　　(3)It is suggested that we (should) hold a meeting next week.

　　It is necessary that he (should) come to our meeting tomorrow.

　　2）在賓語從句中的應用

　　在表示命令、建議、要求等一類動詞后面的從句中。

　　order， suggest， propose， require， demand， request， insist， command， insist + (should) do

　　I suggest that we (should) hold a meeting next week.

　　He insisted that he (should ) be sent there.

　　注意： 如suggest， insist不表示“建議” 或“堅持要某人做某事時”，即它們用于其本意“暗示、表明”、“堅持認為”時，賓語從句用陳述語氣。

　　The guard at gate insisted that everybody obey the rules.

　　判斷改錯：

　　(錯)     You pale face suggests that you (should) be ill.

　　(對)　 Your pale face suggests that you are ill.

　　(錯)　 I insisted that you ( should) be wrong.

　　(對)　 I insisted that you were wrong.

　　3）在表語從句，同位語從句中的應用

　　在suggestion， proposal， idea， plan， order， advice等名詞后面的表語從句、同位語從句中要用虛擬語氣，即（should）+動詞原形。

　　My idea is that we (should) get more people to attend the conference.

　　I make a proposal that we (should) hold a meeting next week.
