外研社版高二必修5 Module 6 Animals in Danger同步教案6重点单词【词条1】endanger【课文原句】 But the Siberian tiger is not the only endangered species. (Page 51)【点拨】 endanger是及物动词，意为“使处于险境；危及”。如：The big fire endangered the animals living in the forest.该句中endanger用过去分词作定语，修饰species，相当于in danger 作后置定语。【拓展】 endanger = en + danger前缀en-常常用来构成动词，表示“使处于某种状态；使成为”。如：enrich“使变得富裕”；enable“使能够”；enlarge“使变大”。【词条2】 worth【课文原句】Often working at night, the poachers shoot whole herds of antelopes at a time, leaving only the babies, whose wool is not worth so much.

(Page 53) 【点拨】 skin作名词时，是“皮肤”的意思，而此处skin用作动词，表示“剥的皮”，属于名词活用。这句话的意思是“这些被猎杀的藏羚羊被就地剥皮，羊毛被运送到印度，在那里，藏羚羊毛被织成披肩。” 再如：You will need four ripe tomatoes，skinned and chopped.【拓展】 英语中，词的活用现象很普遍。如：He fetched some water and watered the flowers in the garden.They shipped some goods on their ship to the lonely island. 【词条4】 condition【课文原句】 The small group of officials who work in the reserve are helped by volunteers who come from all over the country, and who are ready for the difficult conditions of life at 5,000 meters.

He still remembers the days _ he spent with his grandparents in the distant village. b. He still remembers the days _ he worked with his grandparents in the distant village. A. which/that B. when 解析：上面a句中，定语从句中spent缺少宾语，因此应选择答案A；而b句中，定语从句中不缺主语或宾语成分，故选择B项，when 充当句中的时间状语。提示：决定定语从句由关系代词或关系副词引导的关键不在于先行词，而在于从句中缺少何种成分。 *介词前置的现象当定语从句中存在介词时，为了使定语从句与主句的联系更紧密，通常将介词提到引导词之前，即构成介词前置。介词前置应注意的问题有：a. 一旦介词前置，关系代词只能由whom或which中选择：指人用whom；指物用which。不能使用that, 且关系代词也不能省略。如： Do you know the person to whom our teacher was just speaking? This is the very room in which Karl Marx was born.b. 若定语从句中的介词属于结构紧凑的固定搭配，则一般不能前置，以免引起歧义。如： Is this baby the one who you were looking after the whole morning? 此句不可说成：Is this baby the one after whom you were looking the whole morning? c. “介词+关系代词”通常可与关系副词相互转化。如： This is the very room in which Karl Marx was born. = This is the very room where Karl Marx was born.提示：定语从句中介词的选择应取决于从句中的动词，或看介词与先行词的关系而定： *非限制性定语从句定语从句分为限制性定语从句和非限制性定语从句两种。非限制性定语从句与主句的关系较限制性定语从句更松散，常表示并列的意思。其区别于限制性定语从句的标志是主句和从句之间有逗号分隔开，而限制性定语从句则无此标志。另外，在所有的限制性定语从句的引导词中，只有that不能引导非限制性定语从句，其他的均可。在考查非限制性定语从句时，常常考查的是which和as 的区别。请看： as引导非限制性定语从句时，从句既可放在主句之前，又可放在主句之后，而which引导非限制性定语的从句只能放在主句之后。如：As is known to all, the 2008 Olympic Games will be held in Beijing.The sports meeting was put off because of the heavy rain, which made us very disappointed. 在非限制性定语从句中，关系代词as作主语时，其后面必须有动词be；否则只能用which 引导的宾语从句。如：He admires Mr Brown very much，which surprises me. 介绍一个非限制性定语从句的特殊结构：“名词/代词/形容词的最高级/数词+ of + which/whom +定语从句”。如：There are many islands in China, the biggest of which is Taiwan.Do you know the girl，the mother of whom is a famous doctor?4
