Unit 4  Learning efficiently

if they should play the match against us, we should get the team well organized and try our best to beat them.如果他們真的和我們打比賽，我們應該好好地組織并努力戰勝他們。
注意：⑴條件句引導詞if若被省略，該條件句則倒裝。⑵在實際使用中，虛擬語氣和陳述語氣會出現在同一主從復合句里。所以，我們要注意混合語氣、混合時態的使用。比如：
if i had known her earlier, i might have fallen in love with her. but what a pity, now she has been other’s bride.我如果早一些時候認識她，我也許會愛上她的。可是，可惜啊，她現在成了別人的新娘。
if i had been informed yesterday, i should know what to do now.昨天要是有人告訴我，我現在就知道做什么了。
真題：
i _____ pay tracy a visit, but i’m not sure whether i will have time this sunday. (浙江)
a. should              b. might               c. would              d. could 
解析：根據but引導的轉折分句看，visit如果要發生，也應該是周末的事。故選a。
2. 虛擬語氣在賓語從句中的使用
在英語里，wish/　advise/　suggest(建議)/　demand/insist(堅決主張)/　ask(要求)　/　order　/　require　/　desire　/　propose/　urge/　prefer等動詞后的賓語從句用虛擬語氣，除wish以外，其結構都是“should+原形動詞”，should可以被省略。在與這些動詞對應的名詞后的同謂語從句、表語從句里也要用這種結構的虛擬語氣。
i wish i would be manager of this company after i graduate from the college.我希望大學畢業后能做這個公司的經理。
i wish i had enough money on me now.我希望現在手頭有足夠的錢。
i wish i had met the beautiful young lady yesterday.我希望昨天見過那位年輕漂亮的女士了。
the head-teacher asked that the classroom (should) be cleaned right away.班主任要求學生們立即打掃教室。
真題：
1. how i wish every family ______ a large house with a beautiful garden! (02上海)
a. has           b. had           c. will have           d. had had
解析：就本句看，是描述一般情況，表達與現在的愿望之間的距離或者叫與現在事實不符的虛擬語氣。故選b。
2. you can’t imagine that a well-behaved gentleman _____ be so rude to a lady. (上海)
a. might               b. need          c. should              d. would
