句型1 Given the situation , I would recommend that he live on campus.
鑒於這種情況，我建議他住在校園裡。
given the situation 鑒於這種情況。像上面的句子那樣使用分詞的句法，會給人一種高級的語法能力。其實是If I were given the situation (如果我是這種情況)的省略用法。
recommend that sb do sth 推薦某人做…「做...不就好了嗎?」對未來提出建議時使用的動詞。在recommend(推薦)、suggest(建議)、propose(建議)等後面，不受時態和主語的影響，[人]的後面通常是動詞的原形。propose是在有堅定的信念或根據的時候使用，語氣比suggest更強烈。

句型2 If I were in his position, I would talk to the professor during his office hours.
如果我是他的話，我會在教授的辦公時間和他談話。
if I were 以前/曾經…。英語中有一種規則，表述「如果」這一假設的情況時，可能性低的時候，假設為過去時(假設法過去)。
實際的情況：I am not in his position, so l will not talk to the professor. 我不在他的位置，所以我不會跟教授談。
假設的狀況：假設為過去時→If Iwere in his position, I would talk to the professor. (如果我站在他的立場上，我會和教授談談。)
would do sth 會做…。在假設句中will成為would。助動詞would有各種各樣的意思，「一定是」的推測，「想做」的意志的用法，Would you help me out?(能幫我嗎?)像這樣用疑問文的形式表示委婉的請求和勸說。

句型3 I wish I could go back and visit the museum again.
我希望我能返回去再參觀一次博物館。
wish（可能性較低的）希望。希望可能性高的時候使用I hope，I wish通常用於希望性比較低，根本不可能發生的時候。這2個詞組使用時要注意區分。
could（在假設條件句I wish之後）如果能夠… 助動詞can的過去形式，用在I wish後面的句子中可以傳達「如果能做...該多好啊」的語氣。
