牛津高一英語模塊1 Unit1學案1
例如：mr. robert, whom i’ll invite to my new house, is a famous lawyer of our city.
9.recently i have been reading a good book, it was about the relationship between man and nature.
分析 該句中前后兩句之間為逗號，且無連接詞，故后一句應是一個非限定性定語從句，修飾先行詞book,所以it應改為which。
定語從句是歷年高考試題的考查熱點之一，下面就定語從句應特別注意的幾個問題加以舉例分析：
ⅰ.關系代詞which
1.the greens will move into the new house next monday, ＿＿＿it will be completely finished.a.by the time b. by which time c.that d.which
2.water boils at 100℃, ＿＿＿＿＿it changes to gas.a. at which temperature b. at which c. by which temperature d.by which 析：which 引導定語從句時，在從句中除了作主語或賓語外，還可以作定語修飾名詞，常用于“介詞＋which＋名詞”結構中，相當于“and＋介詞＋this/that＋名詞”。所以例1選b；例2選a。
ⅱ.關系副詞when
例1. could you suggest a time ＿＿it would fit you to visit us and try out the machine﹖
例2. think of a time ＿＿＿you were happiest.(senior3,l93)
例3. there was a time ＿＿＿＿＿all scientists were willing to share their results.（senior3,l3） a. that b. when c. which d. where
析：當先行詞為a time(一段時間)時，引導定語從句的關系詞常用when，而不采用that，故以上例題均選b。在我們課本中類似的句子還有：①this was at a time when there was no radio, tv or cinema.(senior2,l70) ②it’s about a time when there were black slaves in north america.(senior1,l53)
ⅲ.關系代詞but
例：there is no one ＿＿＿＿＿wishes peace.a.who b.but c. that d. whom
析：本題句意為“沒有人不希望和平。”but作關系代詞，在定語從句中作主語。but相當于who / that don’t / doesn’t，but本身含有否定意義。故本題選b。
ⅳ.定語從句與強調句及其他從句的混合
例1. it was in the small house ＿＿＿＿was built with stones by his father ＿＿＿＿he spent his childhood.a.which that b.that where c.which which d.where that
析：分析句子結構可知，本句的主句為強調句型，第一空應由關系代詞引導定語從句修飾先行詞house。故本題選a。
例2. the meeting was put off, ＿＿＿＿was exactly ＿＿＿＿we wanted.
a. whichwhich b. as that c. whichwhat d. it that
析：由題意可知，第一空應由關系代詞which引導非限制性定語從句，第二空應由what引導表語從句。故本題選c。
