Grammar
PART. 02
Look at the sentences from the reading passage and answer the question.
1. What do “which” and “whom” refer to in each sentence
“which” refers to “the areas” in sentence (a).
“whom” refers to “the local people” in sentence (b).
Look at the sentences from the reading passage and answer the question.
2. Why do we use prepositions before “which” and “whom”
Because “which” and “whom” serve as the object of the action phrases that end with a preposition.
3. In sentence (a), can we replace “in which” with “where” without changing the meaning
Yes, because “in which” and “where” both mean “in the areas”.
Compare them with the following sentences and answer the questions.
4. What is the difference between the two groups of sentences
Sentences (a) and (b) both contain a clause defining a noun in the sentence. Sentences (c) and (d) are constructed with a pair of simple sentences, with one defining a noun in the other sentence in each pair.
Compare them with the following sentences and answer the questions.
5. Why does the author choose to use sentences (a) and (b) in the reading passage
Because there is a closer link and connection between the item and the clause defining it in sentences (a) and (b). It will also make the passage clearer, and create an emphatic effect on the objects being defined.
Attributive clauses (3) (定语从句)
一、“介词+关系代词”引导的定语从句
关系副词when, where, why引导定语从句时可被“介词+关系代词”代替。在“介词+关系代词”引导的定语从句中，关系代词只能用which或whom，不可用that或who。先行词指物时用which，先行词指人时用whom。
1. “介词 +which”可以替代关系副词 when, where, why
（1）替代when
I still remember the moment at which (= when) I received my diploma and felt a rush of pride. (at 依据 at the moment 确定)
The era during which (= when) the Industrial Revolution took place was full of dramatic changes. (during 依据 during the era 确定)
（2）替代why
I’m curious about the reason for which (= why) he decided to pursue a career in acting. (for 依据 for the reason 确定)
2. 依据与先行词的固定搭配确定使用什么介词
I’ll always cherish the vacation during which I explored the ancient ruins in Greece. (during 依据 during the vacation 确定)
3. 依据定语从句中动词或形容词的搭配来确定介词
He bought a new guitar, on which he spent nearly half of his monthly salary. (on 依据 spend...on 确定)
These are the scientific theories of which she is most skeptical. (of 依据 be skeptical of 确定)
4. 根据定语从句所表达的具体意思来确定介词
Can you see the mountain behind which lies a small village
除了“介词+which”以外，如果定语从句的先行词是“人”，那么也可以用“介词+whom”引导定语从句。
5. “介词 + 关系代词”的其他表达法
（1）如果在whom和which 之前用of 表示所属关系(即of whom, of which表示所属关系)，这时名词需要特指，应加定冠词该名词放在of whom, of which 之前或之后均可。
The book, the cover of which is very attractive, is a best-seller.
The book, of which the cover is very attractive, is a best-seller.
（2）在whom和which之前用of还可以表示部分与整体的关系。这时表示“部分”的数词或代词,放在of whom, of which之前或之后均可。
The class has 30 students, one of whom won the national math competition.
The class has 30 students, of whom one won the national math competition.
The team has ten players, all of whom are highly skilled.
The team has ten players, of whom all are highly skilled.
The club has five founders, the youngest of whom is just 25 years old.
The club has five founders, of whom the youngest is just 25 years old.
二、特殊结构的定语从句
除了限制性定语从句和非限制性定语从句外，还有一些其他形式的定语从句。这些定语从句在实际运用过程中具有较强的灵活性，因此其结构也较为复杂。
1. 嵌入式定语从句
“嵌入式”，相当于在定语从句前加了一个“主谓句”(位置在关系词之后)，让定语从句作其宾语。
She is the only student who we think will pass the difficult exam.
(“who will pass the difficult exam” 作 “we think” 的宾语从句)
They found a painting which they assumed was created by a famous artist.
(“which was created by a famous artist” 作 “they assumed” 的宾语从句)
2. 并列式定语从句
“并列式”，是两个或以上的定语从句相互并列，中间由and或or连接，共同修饰一个先行词，相互之间不包含、不修饰、不重叠。
New York is a vibrant city where dreams are pursued and which attracts countless tourists every year.
3. 多重式定语从句
“多重式”是两个定语从句按先后顺序和不同层次修饰先行词即两个定语从句的谓语表示的动作发生的时间有先有后，其中一个包含另一个。第二个定语从句的关系代词不可省略，中间不能用and连接。
Do you have any stories you want to share that you experienced during your travels
4. 省略式定语从句
在含将来意义的定语从句中，我们可以省略主语和谓语的一部分(主要是情态动词和助动词)，而代之以“介词+关系代词+不定式”。
I’ve collected some materials with which to make a model plane.
(完整形式：I’ve collected some materials with which I want to make a model plane.)
She is looking for a box in which to store her jewelry.
(完整形式：She is looking for a box in which she can store her jewelry.)
5. 分隔式定语从句
定语从句一般紧跟在被它所修饰的先行词之后：但有时候它和先行词之间插人其他成分，使得它与先行词分隔开来，这种定语从句叫作分隔式定语从句。
（1）先行词与定语从句被一个状语分隔。
There are many tourists in the city who are eager to visit the historic sites.
（2）先行词与定语从句被另一个定语分隔。
She has a book with a beautiful cover which was given to her by her best friend.
（3）先行词与定语从句被谓语分隔。
此时，先行词通常是句子的主语，因定语从句较长，主句谓语较短，为使句子结构平衡，常将定语从句移至谓语之后。
The athlete crossed the finish line who had been trailing for most of the race.
