三、定语从句的分隔现象
在英语学习中常常遇到定语从句不是直接位于先行词之后，而是被插入语、介词短语、副词或副词短语、谓语动词、非谓语动词等隔开，这种现象被称作定语从句的分隔现象。

1．Chan’s restaurant on Baker Street,____used to be poorly run, is now a successful business.(2007年浙江卷)
A．that B．which C．who D．where
解析：B 本题考查定语从句。从空前的逗号可知，本题考查的是非限制性定语从句，因此排除A。先行词是地点名词，但是引导在从句中作主语，因此选B。
2．—Is that the small town you often refer to?
—Right, just the one____you know I used to work for years.
A．that B．which C．where D．what
解析：C 了解答语中的插入语you know是解题的突破口。The one在宾语从句中作状语。
3．The film brought the hours back to me______I was taken good care of in that far—away village.
A．until B．that C．when D．where
解析：C when引导定语从句，先行词the hours与定语从句被back to me分隔。
四、as与which之争
as和which都可以引导非限制性定语从句，均可指代整个句子内容，as引导非限制性定语从句，可以用在主句前，又可用在主句后，有时还可插在句中。Which引导非限制定语从句，除了指代整个句子外，还可指单个词，不能放在句首。As引导定语从句，有“正如，就像”之意，常用在as is known to sb., as has been expected, as in mentioned above, as is often the case, as anybody can see, as has been said before等表达中。

1．By serving others, a person focuses on someone other than himself or herself,_____can be very eye-opening and rewarding.(2007年湖南卷)
A．who B．which C．what D．that
解析：B 考查定语从句。先行词为前面整句话所表达的内容，故用which引导一个非限制性定语从句。
2._____is often the case, we have worked out the production plan.
A．Which B．When C．When D．As
解析：D as引导非限制性定语从句，代替整个主句，放在句首。
3．The owner of the cinema needed to make a lot of improvements and employ more people to keep it running,____meant spending tens of thousands of pounds.
A．who B．that C．as D．which
解析：D从句中缺少主语，which指代前面的整个主句并在从句中作主语，that不能用在非限制性定语从句中。As意为“正如，就像”，不符题意。
4．______I explained on the phone, you request will be considered at the next meeting.
A．When B．After C．As D．Since
解析：C表示“依据，正如……”之意时，用as引导。Which不能用在句首。
五、对whose用法的考查
Whose引导定语从句，既可指人，又可代物，在从句中作定语。

A．the real name B．what his real name C．his real name D．whose real name

六、名词/代词/数词+关系词引导定语从句
真题再现
1．Last week, only two people came to look at the house,_____wanted to buy it.(2007安徽卷)
A．none of them B．both of them C．none of whom D．neither of whom
解析：D 分析该题，该句中含有两个句子，用逗号隔开，缺少连接词，所以不可用A、B项，用whom引导定语从句，从该句的信息词two people可知答案D，neither表示“两者都不”。
2．The factory produces half a million pairs of shoes every year, 80%______are sold abroad.
A．of which B．which of C．of them D．of that
解析：A 数词+关系词引导定语从句。介词后不用that。若选C，需在80%前加and。
七、准确判断代替先行词的关系词在定语从句中作任何成分，正确选择关系词。
关系代词（who,whom,whose,which,that）代替的先行词是表人或物的名词或代词，在从句中充当主、宾、定语等成分，作主语时，从句谓语动词的数要与先行永嘉保持一致。关系副词引导定语从句时，可在从句中作状语，分别表示时间、地点或原因。

1．—Where did you get to know her?
—It was on the farm_____we worked.(2007年山东卷)
A．that B．there C．which D．where
解析：D 考查定语从句。Where在定语从句中作状语。
2．We shouldn’t spend our money testing so many people, most of_____are healthy.(2007北京卷)
A．that B．which C．what D．whom
解析：D 分析该句，第二分句应该是定语从句，修饰先行词people，所以用whom。What只能引导名词性从句；that不可引导非限制性定语从句，也不可用在介词后面；which不可指人。
3．—Do you have anything to say for yourselves?
—Yes, there’s one point_____we must insist on.
A．why B．where C．how D．/
解析：D 引导词在句中作on的宾语，故只能用which, that或省略。
