考試時(shí),當(dāng)出現(xiàn)類似形式的題目而確實(shí)又看不懂句子意思時(shí),應(yīng)傾向于選擇which + 單數(shù)動(dòng)詞的那個(gè)選項(xiàng)。
6)They have made another wonderful discovery, ______ of great importance to science.
A. which I think is
B. I think which is
C. which I think it is
D. I think of which is
解題思路:英語中的連接詞一般都是放在從句的最前面,據(jù)此,可以排除B、D選項(xiàng);A、C的區(qū)分點(diǎn)是"it", 想一下本節(jié)的第一題,就能正確選擇答案A了。此類題目中,I think應(yīng)理解為"插入語",要熟悉這種形式,
又如:
He is the man ______ I suppose is capable of finishing this task.
該題應(yīng)填who而不是whom
(在從句中)當(dāng)狀語時(shí):關(guān)系副詞where及whenwhere : 當(dāng)先行名詞在從句中當(dāng)"地點(diǎn)狀語"時(shí),用關(guān)系副詞where連接
例如:
The crime rate rises in cities where the unemployment rate increases. (失業(yè)率高的城市犯罪率也高。) 句中的where = in cities, 表示行為發(fā)生的地點(diǎn)。
這里的要點(diǎn)是能否區(qū)分是用that (which)還是用 where, 即:是做"主語、賓表語",還是做"地點(diǎn)狀語",例如:
I love the small town that we visited last week.
句中"town"做動(dòng)詞"visited"的賓語,即"參觀過的小鎮(zhèn)",故用that連接。
I love the small town where I lived during my childhood.
句中"town" 是動(dòng)詞"lived"的地點(diǎn),即"童年時(shí)住過的小鎮(zhèn)",故用where.
這也是定語從句的一個(gè)考點(diǎn)。
when : 當(dāng)先行名詞在從句中當(dāng)"時(shí)間狀語"時(shí),用關(guān)系副詞when連接, 例如:
July is the month when we have a lot of rain. (七月是多雨的月份。)
注意"when"定語從句后推的現(xiàn)象,例如:
I think (that) the day will finally come when air pollution can be put under control. (我認(rèn)為空氣污染得以控制的一天最終會(huì)來到。)
放在主句后面作非限制定語從句時(shí)(前面一般加","號(hào)),"when"一般譯為"此時(shí)","那時(shí)", 例如:
The meeting will be put off until next month, when we will have made all the preparations. (會(huì)議將推遲到下月,那時(shí)一切就準(zhǔn)備就緒了。)
另一個(gè)關(guān)系副詞是why,由于它固定與the reason搭配, 即: the reason why,不難理解,一般也不作為考試的重點(diǎn)。例如:
This is the reason why the electronic computer cannot entirely replace man. 這就是(為什么)電子計(jì)算機(jī)不能完全代替人的原因。
whose (= of which / whom):做醫(yī)學(xué)全.在線zxtf.net.cn先行詞(不管是人還是物)的定語,漢語為"…的",不要考慮是否是限制性或非限制性定語從句, 例如:
Pay attention to that boy whose temperature is very high. (理論上也可以寫成:Pay attention to that boy the temperature of whom is very high. 注意那個(gè)男孩,他的體溫很高。(非限制性) / 注意那個(gè)體溫很高的男孩。(限制性)
介詞 + which (whom)
先看兩個(gè)句子:
This is the house. He has lived in the house for over 30 years.
變?yōu)椤ㄕZ從句
This is the house in which he has lived for over 30 years.
上述句子中,先行詞在從句中充當(dāng)介詞賓語,形成"介詞 + which / whom"的形式,考試時(shí)要求作出1)要不要介詞;2)若要,使用什么介詞的判斷。由于英語中介詞搭配多為習(xí)慣用法,沒有多少規(guī)律可循,因此這是定語從句考試的一個(gè)難點(diǎn)。
