試題分析：句意:--每個學生一天必須有一個小時的鍛煉身體的時間這是國家普遍的要求。--是的，到了我們應該注意鍛煉身體的時候了。Required后的主語從句用虛擬語氣，從句謂語動詞用should+do;這里是固定句式it is high time+that should+do 或did,故選B。
點評：本題難度適中。虛擬語氣是近幾年高考的熱點，虛擬語氣的情況復雜，形式多樣，需要考生牢記它們的不同的用法，再根據(jù)不同的語境分析句子應該用哪種情況的虛擬。
即學即練：—You _________ have set aside more time to play with our kids.
—I wish I _________, but you know how busy I was.
A. should; would          B. could; did
C. might; should      D. should; had
解析：D�？疾樘摂M語氣在wish從句中的用法。由句中“should have set aside”及“how busy I was”可知，該句表示與過去事實相反。故選D。
