    詳解：
　　83. B。once的意思是“一旦”，又如：Once you have taken this decision, there will be no going back, ie you will not be able to change your mind. 一旦作出這個(gè)決定，你就不能改變主意。Once you understand this rule, you’ll have no further difficulty. 一旦明白了這條規(guī)則，就再也沒(méi)有困難了。
　　84. C。將四個(gè)選項(xiàng)的意思分別套入句中，只有填unless時(shí)意思最通順。為便于理解，句子也可轉(zhuǎn)換成：Most birds find it safe to sleep in the trees, but they don’t use a nest unless they have eggs or young chicks.
　　85. B。it was some time before…是一個(gè)很有用的句型，其字面意思是“在……之前過(guò)了一段時(shí)間”，通�？赊D(zhuǎn)譯為“要過(guò)一段時(shí)間才會(huì)……”，如：It will be five years before we meet again. 五年以后再見(jiàn)。It may be a matter of months before it’s ready. 要準(zhǔn)備好可能得數(shù)月時(shí)間。
　　86. A。unless的意思是“除非”，又如：Don’t call me unless you need help. 除非你需要幫助否則別打電話找我。Unless you change your mind, I won’t be able to help you. 除非你改變你的想法，否則我不能幫助你。
　　87. A。if在此引出一個(gè)虛擬條件。又如：If he had asked me, I would have had to tell him the truth. 如果他問(wèn)我，我就不得不告訴他真相了。If I had not got married, I would still have been living abroad, 如果我沒(méi)結(jié)婚，我就會(huì)仍然住在國(guó)外。
　　88. D。while在此表示“盡管”“雖然”，又如：While the work was difficult, it was interesting. 盡管工作有難度，但很有趣。/ While I understand what you say, I can’t agree with you. 雖然我理解你的意思，但我還是不同意。
　　89. A。until的意思是“直到……時(shí)”“在……之前”，如：We always have to wait until the last customer has left. 我們總得等著最后一位顧客離去。
　　90. C。as if意為“好像”“似乎”，now that意為“既然”，even though意為“盡管”“雖然”，so that意為“為了”。比較四個(gè)選項(xiàng)，只有選C最合適。
　　91. C。in case意為“以防萬(wàn)一”，又如：I bought the car at once in case he changed his mind. 我馬上買(mǎi)下了那輛汽車，以免他變卦。I don’t let him climb trees in case he tears his trousers. 我不讓他爬樹(shù)，以免撕破褲子。
　　92. C。比較：now that意為“既然”；if only意為“只有”；so long as意為“只要”；every time意為“每次”。分別代入句中，只有填as long as時(shí)，意思最通順。
　　93. D。根據(jù)句意思，只有填because意思最通順。
　　94. A。根據(jù)句意，只有填before時(shí)意思最通順。It’ll be some time before…是英語(yǔ)中一個(gè)很有用的句式，其意為“要過(guò)一段時(shí)間才……”，如：It’ll be some time before we meet again. 要過(guò)一段時(shí)間我們才能見(jiàn)面。有時(shí)也可用其他時(shí)態(tài)，如：It was some time before we struck the track. 我們用了很長(zhǎng)時(shí)間才找到了路。
　　95. C。本題很容易讓考生受思維定勢(shì)的負(fù)面影響，見(jiàn)到so馬上選擇that，殊不知此題考查的是when引導(dǎo)的時(shí)間狀語(yǔ)從句，句意為：南希去年拜訪悉尼的朋友時(shí)過(guò)得非常開(kāi)心。如果選A，則句意為：南希玩得如此開(kāi)心以至于拜訪了悉尼的幾個(gè)朋友。顯然，意思不合邏輯。
